Kidney Transplant, Sleep Disorder May Add Up to Trouble

November 19, 2009
Heart disease, stroke more likely for organ recipients with sleep apnea, study finds. Kidney transplant patients with sleep apnea are at increased risk for high blood pressure, heart disease and stroke, Hungarian researchers say.

The study of 100 kidney transplant recipients found that 25 percent had moderate to severe sleep apnea, a rate similar to that seen in kidney disease patients on dialysis awaiting a transplant. This means that both types of patients who have the breathing-related sleep disorder should be considered at high risk for serious heart-related complications, the study authors noted.

Appalachia, Southeast Hit Hardest by Obesity and Diabetes

November 19, 2009
CDC county-by-county analysis finds some areas with 1 in 10 adults already diabetic. While rates of obesity are climbing across America, they are especially high in sections of Appalachia and the Southeast, the U.S. Centers for Disease Control and Prevention reports in its first county-by-county survey.

Obesity Rolling Back Gains in Heart Health

November 17, 2009
Studies show risk factors rising among children and adults, with many denying they have a problem. Surging obesity rates, especially among children, may be putting the brakes on progress made in the past few decades against heart disease, researchers report.

And it doesn't help that many obese or overweight Americans still consider their weight "normal," as one study found.

One of several studies on the subject of obesity presented Tuesday at the American Heart Association (AHA) annual meeting in Orlando, Fla.

Folic Acid Fortification Might Boost Cancer Risk

November 17, 2009
Norwegian study found supplementation raised chances of disease by 21%. Although folic acid fortification of foods can prevent many birth defects, it may also increase the risk for developing cancer, Norwegian researchers report.

Since 1998, many countries have mandated folic acid (vitamin B9) fortification of foods to decrease the incidence of neural-tube defects in newborns. By October 2009, the flour produced in these countries, plus the flour that is fortified voluntarily, represented 30 percent of the world's wheat flour produced in large mills.

Incidence of High Cholesterol Drops in U.S.

November 17, 2009
Down by 30 percent, but those with high levels often don't know it, study finds. The good news is that a new report shows the percentage of American adults with high LDL cholesterol, the "bad" kind that clogs arteries, decreased by about one-third between 1999 and 2006.

The bad news is that too many of those who have dangerously high levels of LDL cholesterol don't know it, said study author Dr. Elena V.

Baby Boomers May Prove More Disabled Than Their Elders

November 13, 2009
Wave of disabilities could overburden health-care system, researchers fear. Baby boomers in the United States may enter their 60s with far more physical disabilities than previous generations, which could spell trouble for an already overburdened health-care system.

That's the finding of University of California, Los Angeles researchers who analyzed data from the 1988 and 1999 National Health and Nutrition Examination Surveys to identify changes in disability trends among older adults.

The study authors looked at four areas of disability: basic daily living activities, such as walking from room to room and getting in and out of bed; instrumental activities, such as doing household chores or preparing meals; mobility, including walking one-quarter mile or climbing 10 steps without stopping for rest; and functional limitations, such as stooping, crouching or kneeling.

Study Links Yo-Yo Dieting to Addiction

November 12, 2009
Rats fed sugary chow suffered withdrawal when regular meals returned. Not a big fan of dieting? Join the club. But new research in rats hints at why weight loss is so tough .

Gut Bacteria Might Be Making People Fat

November 11, 2009
Study in mice suggests link between intestinal microbes, diet and obesity. Eating a Westernized diet with lots of sugar and carbohydrates caused almost instantaneous changes in the gut flora of mice .

Fasting on Alternate Days May Make Dieting Easier

November 11, 2009
Heart health could also benefit from this plan, researchers find. To get down to a healthy weight, obese and overweight people often struggle to cut their daily caloric intake by a necessary 15 percent to 40 percent.

But new research suggests that a twist on alternate-day fasting may make dieting easier to tolerate and boost heart health to boot.

"This diet has been around about 20 years, but its effect on weight loss hadn't really been studied," Krista Varady, an assistant professor of kinesiology and nutrition who led a research team at the University of Illinois at Chicago, said in a news release.

Teen Obesity Ups MS Risk in Women

November 10, 2009
Researchers suspect lower vitamin D levels may be to blame. While there are plenty of good reasons to avoid obesity in your teens, a new study now suggests that extra weight in adolescence may increase your risk of multiple sclerosis (MS) later.

Reporting in the Nov. 10 issue of Neurology, Harvard researchers found that being obese at age 18 more than doubles a woman's risk of developing MS later in life compared to her slimmer peers.

Obesity Seems to Alter Heart Structure

November 09, 2009
Result may be left atrial enlargement, study finds. Obesity is a major risk factor for left atrial enlargement, which increases the risk of atrial fibrillation, stroke and death, a new study shows.

Atrial fibrillation is the most common type of arrhythmia (an irregular heart rhythm or heartbeat).

Researchers analyzed data on 1,212 men and women, aged 25 to 74, in Germany who were followed for 10 years.

To Feel Better, Low-Fat Diet May Be Best

November 09, 2009
Comparison of plans finds differences in mood despite similar weight loss. Both a high-fat, low-carbohydrate diet such as the popular Atkins program and a low-fat, high-carb diet appear to help people lose pounds over the course of a year.

But as for mood? Only the low-fat diets will result in long-term improvement in mood, according to a study in the Nov. 9 issue of Archives of Internal Medicine.

Genes Linked to 'Pot' Belly

November 05, 2009
And excess consumption of saturated fats raises obesity risk, researchers find. New research sheds light on the possible link between the genes you inherit and the size of your belly.

Participants in a French study doubled their risk of having fat around the abdomen if they had a certain genetic trait, and the more of these traits one had, the greater the risk for a pot belly.

The study was looking at metabolic syndrome, a condition in which abdominal obesity, high cholesterol and high blood pressure combine to raise the risk of several diseases such as stroke, heart disease and type 2 diabetes.

Green Tea May Help Prevent Oral Cancer

November 05, 2009
Small study reports evidence of cancer-fighting properties. A new study appears to add to growing evidence that green tea might help protect against cancer.

Fast Eating Limits Gut Hormones That Induce Fullness

November 04, 2009
The result is overeating, research shows. Eating too fast can lead to overeating because gulping down food limits the release of hormones in the gut that trigger the feeling of being full, Greek researchers have found.

For the study, volunteers ate 300 milliliters of ice cream at different rates. Blood levels of glucose, insulin, lipids and gut hormones were measured before and after consumption of the ice cream.

Folate Levels in Pregnancy Tied to ADHD in Offspring

November 03, 2009
Prenatal nutrition seems to affect child's nervous system, brain growth, researchers say. Low folate levels during pregnancy are associated with higher odds for attention-deficit/hyperactivity disorder in offspring aged 7 to 9, new research has found.

The findings seem to support the long-held belief that folate (folic acid) levels in expectant mothers influence their children's nervous system development.

The researchers also found that children of mothers with low folate levels had notably smaller head circumference at birth, which may indicate a slower rate of prenatal brain growth.

Living With Less TV, More Sweat Boosts Weight Loss

November 05, 2009
Home environment plays role in effort to drop pounds, experts say. If you want to lose weight, exercise and diet are crucial. But a new study says other factors appear to play a role, too .

Diet, Exercise Thwart Diabetes

Study

October 29, 2009
Lifestyle changes really do work to prevent type 2, experts say. Diet and exercise can keep diabetes at bay for a decade, cutting the risk for the disease by more than a third in the most susceptible people, a new study finds.

Let Kids Sleep Late on Weekends to Fight Fat

Study

October 28, 2009
Too little shuteye contributes to obesity, researchers say. Letting children sleep late on weekends and holidays might help them avoid becoming overweight or obese, a new study suggests.

Researchers in Hong Kong found that children who got less sleep tended to be heavier (as measured by body mass index, or BMI) than children who slept more. But among children who slept less than eight hours a night, those who compensated for their weekday sleep deficit by sleeping late on weekends or holidays were significantly less likely to be overweight or obese.

Antipsychotic Drugs Spur Dramatic Weight Gain in Kids

October 27, 2009
Researchers urge other alternatives, close monitoring of patients. Children and teens who take medicines for conditions such as schizophrenia, bipolar disorder and autism tend to put on a substantial amount of weight, a new study finds.

The worry is that excessive weight gain and other metabolic changes in childhood can place kids at risk for chronic health problems as adults. Some of these medicines, collectively known as "atypical antipsychotics," have been linked to increased blood-fat levels.

Fitness Fades Fast After 45

October 26, 2009
But healthy habits can stave off the inevitable declines, research finds. The declines in fitness that accompany growing old typically speed up after the age of 45, new research shows.

But people can slow the inevitable by staying lean, exercising and refraining from smoking.

The findings, appearing in the Oct.

Where You Put on Pounds May Influence Clot Risk

October 26, 2009
Big hips in women, wide waists in men spell trouble, study finds. The location of excess body fat appears to affect the risk of dangerous blood clots in veins, although that location differs in men and women, a new Danish study indicates.

The 10-year study found that bigger hips are associated with an increased risk of venous thromboembolism (VTE) in women but not men, while a wider waistline was associated with increased risk in men, according to a report published online Oct. 26 in the journal Circulation.

Exposure to Holocaust May Have Raised Cancer Risks

October 26, 2009
Survivors offer clues to the impact of severe physical, psychosocial suffering, researchers say. Among Jewish survivors of World War II, those who were potentially exposed to the Holocaust have an increased risk of cancer, likely due to physical and mental stress, an Israeli study has found.

University of Haifa researchers compared cancer rates in more than 300,000 Israeli Jews who were born in Europe and immigrated to Israel either before World War II (non-exposed) or after the war (potentially exposed).

Compared to the non-exposed group, those in the potentially exposed group had a statistically significantly increased risk for cancer, especially breast and colorectal cancer, the researchers found.

Liposuctioned Fat Can Be Used for Breast Augmentation

October 26, 2009
Method may be safe alternative to implants, researchers say. Using liposuctioned fat for breast augmentation may be a viable alternative to implants for some women, according to a new study.

The use of fat injections for breast augmentation has been the subject of ongoing debate because of a lack of research and worries that the fat may calcify and obscure mammograms, be mistaken for cancer or be re-absorbed by the body.

The study included 50 women, aged 17 to 63, who had 55 fat-grafting procedures (five women were grafted twice) to their breasts with fat taken from their upper thighs and other areas.

Big, Beefy Football Players May Face Heart Problems Later

October 26, 2009
Physical activity may not protect heart from complications of extra weight, study finds. Crushing the notion that you can be both fat and fit, new research has found that current professional football linemen already have some risk factors for heart disease.

In a study comparing professional football players to minor and major league baseball players, researchers found that football linemen were more likely to have higher fasting blood sugar levels, larger waist circumferences and a greater waist-to-height ratio.

Although the idea that a football player could be at risk for heart disease might seem paradoxical because football players have to be in top physical condition, the lineman position also requires players to bulk up, with many tipping the scales at more than 300 pounds.

Heavy Patients Get Little Respect From Doctors

October 23, 2009
Study finding shows doctors have to realize obesity is a disease, expert says. Mirroring a societal stigma against the obese, Johns Hopkins researchers report that doctors appear to have less respect for their heavy patients.

"Society, in general, has negative attitudes towards patients with obesity and physicians may be mimicking what is found in society," said lead researcher Dr. Mary Margaret Huizinga, an assistant professor of general internal medicine at Hopkins.

Diabetes Drug May Boost Weight Loss in Obese Patients

October 23, 2009
Combo of diet, exercise and injections helped non-diabetics shed pounds, study finds. The diabetes drug liraglutide helps obese people without diabetes lose weight, researchers have found.

The study authors also reported that high doses of liraglutide were more effective at helping people shed pounds than the weight-loss drug orlistat.

In the study, which included 564 diabetes-free obese patients aged 18 to 65 at 19 sites in Europe, participants were randomly selected to receive one of four injected doses of liraglutide (1.

Red-Grape Compound May Improve Diabetes

October 22, 2009
But so far resveratrol works only as an injection into the brain of mice, study finds New research provides further insight into how a health-boosting compound found in red grapes may help the body fend off type 2 diabetes.

But scientists have only seen the effect in mice who received injections in the brain, and no evidence has emerged that consuming red wine or other products made with grapes will alleviate the blood sugar disease.

The findings do tell scientists about how the compound known as resveratrol works on the brain, said senior study author Roberto Coppari.

For Obese, Weight Gained in Pregnancy May Not Leave

October 21, 2009
Overweight women have tougher time shedding those excess pounds, study finds. Obese women who gain more than 15 pounds during pregnancy tend to retain much of it long after delivery, a new U.S. study finds.

Super Obesity Ups Risk of Dying After Weight-Loss Surgery

October 21, 2009
Deaths also more common among those with chronic diseases, study finds. People who are super obese and those with the most chronic health problems face an increased risk for dying within a year after weight-loss surgery, a new U.S. study has found.

Fish Oil Supplements Don't Help Depressed Heart Patients

October 20, 2009
Those who took them with antidepressant fared same as those who didn't. In a surprise and not very welcome finding, researchers report that fish oil supplements do not ease depression in individuals who suffer from both depression and coronary heart disease.

Participants in the study, which is published in the Oct. 21 issue of the Journal of the American Medical Association, were also taking the antidepressant sertraline (Zoloft).

Glucosamine Fails Osteoarthritis Test

October 20, 2009
Popular supplement doesn't prevent loss of cartilage in knee, study finds. Glucosamine takes a hit in a new study that finds it doesn't prevent cartilage loss in people with osteoarthritis of the knee, University of Pittsburgh researchers report.

Many arthritis sufferers take glucosamine supplements in an attempt to reduce pain or to slow the disease's progression, but previous studies have questioned its effectiveness.

In this new study, Dr.

School Meals Need to Get Healthier

Soda Taxes Not Making a Dent in U.S. Waistlines

October 16, 2009
Small increases in cost for sugary drinks haven't slowed obesity epidemic, study finds. Current state taxes and levies on soft drinks are slowing consumption, but not enough to curb the obesity epidemic in the United States, researchers say.

In an analysis of 16 years of data (1990 to 2006) on how various forms of soft drink taxation affected body mass index, researchers found that taxation has only a minor effect on BMI, which is a measurement based on weight and height. For example, a 1 percent tax increase causes a BMI decrease of 0.

Smog Tougher on the Obese

October 15, 2009
Study finds sharp hikes in blood pressure when overweight, air pollution combine. Air pollution appears to hit the obese hardest, causing significant increases in blood pressure, a new study finds.

Air pollution has been linked to a variety of health problems including asthma, heart disease and diabetes, but this is the first time obesity has been taken into account, researchers say.

"For those who are obese, exposure to air pollution further exacerbated systolic blood pressure and pulse pressure," said lead researcher Srimathi Kannan, an assistant professor at the School of Public Health and Health Sciences of the University of Massachusetts at Amherst.

Want Leaner Kids? Parents May Need to Toe the Line

October 11, 2009

Ex-NFL Players Hold Their Own Health-Wise

October 09, 2009
Former pros have lower risk of heart disease, suggesting early fitness pays off, researcher says. A recent report linking professional football to an increased risk of Alzheimer's disease set off alarms in locker rooms across the nation, but the news for aging athletes isn't all bad. Retired pro football players have fewer heart disease risk factors than other men in the same age group, a U.S.

Troubled Minds Can Mean Wider Waistlines

October 07, 2009
Repeat episodes of anxiety, depression tied to weight gain, study finds. Common mental health disorders, such as anxiety and depression, may increase a person's risk of obesity, and people with repeated episodes of these disorders are particularly at risk, British researchers say.

In the study, published in the Oct. 7 online edition of the BMJ, researchers analyzed data from four medical screenings of 4,363 British civil servants aged 35 to 55 conducted over 19 years (1985 to 2004).

Nutrition Still Not 'A' Grade in U.S. Schools

Studies

October 07, 2009
Guidelines are helping, but more is needed to stem teen obesity, researchers say. Schools in the United States are becoming healthier places thanks to more nutritious food and an increased focus on exercise, but still more is needed to combat teen obesity, a series of studies concludes.

Among the findings of the studies, which appear in a September supplement to the Journal of Adolescent Health:

Students in California schools have a choice of healthier foods and beverages. More than 85 percent of 56 schools studied complied with state beverage standards that went into effect two years ago, and nearly 64 percent meet standards regarding healthy food in their cafeterias and other venues.

Exercise in Adolescence May Cut Risk of Deadly Brain Tumor

October 06, 2009
Physical activity later in life didn't seem to matter, study finds. Exercising during adolescence may help guard against a deadly form of brain tumor in adulthood, new research suggests.

The study also found that avoiding obesity during the teen years was associated with a lower risk of developing the cancerous brain tumors called gliomas, while being tall increased the chances of such malignancies.

The study appears in the Nov.

Schools Provide Less Junk Food Today

CDC

October 05, 2009
Teens less likely to get soda, unhealthy snacks, but some states still lag behind, report finds. The amount of unhealthy foods and drinks available in American secondary schools has declined, especially in states with strong school nutrition standards and policies, says a federal government study released Monday.

Among 34 states that collected 2006-08 data, the median percentage of secondary schools that didn't sell soda, or fruit drinks that aren't 100 percent fruit juice, increased from 38 percent in 2006 to 63 percent in 2008. The median percentage of secondary schools that didn't sell candy, or salty snacks not low in fat, also rose from 46 percent to 64 percent, according to the U.

Mediterranean Diet May Help Prevent Depression

October 05, 2009
Lower incidence seen in Spanish study. People who followed the Mediterranean diet, an eating regimen that is rich in fruits, vegetables, whole grains, fish and nuts, were less likely to develop depression in a Spanish study.

"We are speaking of a relative reduction in risk of 42 percent to 51 percent," said study co-author Dr. Miguel A.

Delaying Weight-Loss Surgery May Leave Teens at Risk

October 02, 2009

Workplace Wellness Seems to Really Work

September 30, 2009
Investing in employee health reduces medical costs and increases productivity, heart experts say Workplace wellness programs are an effective way to reduce major risk factors for heart disease, such as smoking, obesity, high blood pressure and diabetes, says a new American Heart Association policy statement.

Each year, heart disease costs the United States about $304.6 billion, the association says.

Obese Middle-Aged Women Face Unhealthy Future

September 30, 2009
Extra weight cuts chances for long, healthy life by nearly 80%, study finds. If excess weight doesn't kill you by old age, it could make your life miserable in the form of chronic health problems and impaired mental fitness.

According to a new study, women who are obese in middle age are almost 80 percent more likely to have multiple health problems by the time they reach age 70.

"Those who gained weight [in adulthood] actually suffered reduced odds of healthy survival," said study author Dr.

No Osteoarthritis Seen in Obese Mice Without Leptin

September 29, 2009
Hormone linked to appetite may also influence arthritis risk, researchers find. The appetite-regulating hormone leptin may contribute to osteoarthritis in obese people, according to a new study that suggests that skeletal wear and tear caused by excess weight isn't the only cause of the painful and debilitating condition.

Duke University researchers found that extremely obese mice didn't develop osteoarthritis if their bodies didn't have leptin. In fact, joints in obese mice without leptin appeared healthier than those in normal mice.

When Pounds Go, Sleep Apnea May Improve

September 28, 2009
10 percent weight loss increases remission odds, but any amount helps, experts say. People with sleep apnea who are also obese may triple the chances of eliminating their sleep problems by losing weight, a new study suggests.

Losing about 10 percent of their body weight was enough to bring on total or near-total remission, said Gary Foster, head of the Center for Obesity Research and Education at Temple University in Philadelphia, and lead author of the study.

"It's been clear that obesity increases the risk of sleep apnea but less clear that if obese people or people with type 2 diabetes lost weight, it would result in significant improvements in their sleep apnea .

Vitamin D May Improve Melanoma Survival

September 27, 2009
But levels are too low in many Americans, researchers say. Higher levels of vitamin D are linked to less severe, less deadly melanoma lesions in people with skin cancer, new research suggests.

The findings provide more support for the idea that vitamin D is crucial to skin health. Many Americans, however, don't get enough of it, perhaps because they limit sun exposure and drink less milk than in the past.

With Fancy Coffees, Calories Can Add Up

September 23, 2009
Popular blended beverages may be 'weighing you down,' health official says. Love your afternoon pick-me-up? A blended coffee beverage might hit the spot but pack on the pounds, a new study suggests.

A survey of about 3,000 purchases from 115 restaurant chains in New York City found that servings of brewed coffee or tea average about 63 calories, even when some include milk and sugar. But get a blended beverage and you're looking at 239 calories on average .

Cost Savings Adds to Value of Preventing Chronic Disease

September 23, 2009
Avoiding diabetes, high blood pressure can add years to life, researchers say. Prevention of chronic diseases such as diabetes, obesity and high blood pressure improves the lives of older Americans and also reduces medical costs, study findings show.

Researchers looked at a group of 51- and 52-year-olds from across the nation and projected their future state of health and medical costs if they could avoid developing certain chronic diseases. In a 51-year-old, prevention of obesity would extend life by 0.

Successful Dieters Show Unique Brain Patterns

September 23, 2009
Scans found regions related to inhibition, self-control were more active. New research suggests that people who have successfully lost weight will activate certain parts of their brains when confronted with images of food.

While preliminary, the findings indicate that those who shed pounds .

Leukemia Cells May Hide in Fat Tissue

September 22, 2009
Finding explains why obese children have higher relapse rates, researchers say. Leukemia cells can hide in fat tissue to evade chemotherapy, which may explain why obese children with leukemia are more likely to develop chemotherapy resistance and have higher relapse rates, researchers say.

A previous study found that obese children with leukemia are 50 percent more likely to relapse than lean children.

In this new study, researchers observed that obese mice with leukemia had higher relapse rates than lean mice after they were treated with the first-line chemotherapy drug vincristine.

Diet, Exercise May Slow Kidney Disease Progression

September 18, 2009
Obese patients can also benefit from weight-loss surgery, review finds. Shedding pounds may be good for most people, but especially for those with kidney disease, a new study has found.

A review of previously published studies on weight loss through diet, exercise or surgical intervention found that the weight loss had a positive effect on kidney function in obese kidney disease patients, according to the article appearing online Sept. 17 in the Clinical Journal of the American Society of Nephrology.

Middle-Age Heart Risk Factors Shorten Men's Lives

September 18, 2009
Smoking, hypertension, high cholesterol cut 10 years of life, study finds. Middle-aged men with risk factors for heart disease such as smoking, high blood pressure and high cholesterol are taking 10 to 15 years off their lives compared to men without these troubles, British researchers say.

Although death from heart disease has been declining, in part due to better control of cardiovascular risk factors and better care, this is the first study that looks at death from heart disease in terms of life expectancy, the researchers said.

"The good news is that all of us can make changes to live a healthy life," said lead researcher Dr.

Drinking, Weight, Depression Linked in Young Women

Study

September 17, 2009
Treatment for one of these issues should take into account the others, report says In women under age 30, drinking to excess, overeating and depression may all be tied together, according to new research.

A study in the September/October issue of General Hospital Psychiatry found that women with alcohol abuse issues at age 24 had three times the risk of obesity by age 27. And women who were obese at 27, the researchers found, were twice as likely to be depressed by the time they turned 30.

More Whole Grains May Mean Less Fat

September 17, 2009
In older eaters, fiber content of cereals has biggest effect, study finds. Eating more whole-grain foods may help reduce body fat in older adults, says a new U.S. study.

Insulin-Linked Genes Tied to Body's Internal Clock

September 17, 2009
Discovery could shed light on conditions related to sleep-wake cycle. Genes that regulate insulin in the body also play a role in the timing of the body's sleep-wake cycle, researchers say, and this finding that could potentially lead to treatments for disorders that arise when circadian rhythms are disrupted.

The insulin-control system, which governs how the body processes sugar, may also reset our internal clock, according to the study published online Sept. 17 in Cell.

'Soda Tax' Wins Health Experts' Support

September 16, 2009
Researchers cite a win-win for health care and obesity, but beverage industry balks at proposal. A national tax of 1 cent per ounce of soda and other sugary drinks could stem the United States' obesity epidemic, while generating $14.9 billion the first year alone, health experts say.

That windfall could help finance proposed health care reform, while also funding programs to prevent obesity, say a group of prominent researchers in an article in the Sept.

Anxious Kids at Risk for Obesity in Adulthood

September 15, 2009
Treating emotional problems early could improve long-term health, researchers say. Children with emotional difficulties have a greater risk of becoming obese in adulthood, new research has found.

In the study, published online Sept. 11 in the journal BMC Medicine, researchers from the MRC Social, Genetic and Developmental Psychiatry Center at the Institute of Psychiatry at King's College London, examined data from about 6,500 members of the 1970 British Birth Cohort Study.

Most Adult Americans at Some Risk for Heart Disease

September 14, 2009
Surging obesity rates have reversed gains, and now less than 8% have no heart disease risk factor, study finds. Decades of steady progress against heart disease may be on the wane, experts say, with a new study showing that only 7.5 percent of Americans are now in the clear when it comes to heart disease risk factors.

Curbing Obesity Epidemic Key to Health Care Reform

Experts

September 11, 2009
Overweight is major contributing factor for chronic disease, U.S. health groups say. A diverse alliance of payer, provider and consumer organizations, girded by two former U.S. Surgeons General, on Wednesday urged policymakers to address the nation's obesity epidemic as part of federal health care reform legislation.

Metabolic Syndrome May Raise Risk of Peripheral Artery Disease

September 09, 2009
Women much more likely to develop PAD if they had constellation of other symptoms, researchers found. Women with metabolic syndrome are at high risk of developing peripheral artery disease, a condition that dramatically raises the risk of heart disease and stroke.

Using data on more than 27,000 women taking part in the Women's Health Study, researchers identified participants with metabolic syndrome, a collection of symptoms including abdominal obesity, high blood pressure, low HDL ("good") cholesterol, high triglyceride levels and insulin resistance.

Women were considered to have metabolic syndrome if they had three or more of those symptoms.

Acupuncture May Help Relieve Polycystic Ovary Syndrome

September 04, 2009
Exercise also improves symptoms and related risk factors, study finds. Acupuncture and exercise may help women better handle the symptoms and risks that come with hormone imbalances caused by certain ovarian cysts, Swedish researchers report.

About one in 10 women of reproductive age have polycystic ovarian syndrome, a condition that can start in the teen years and cause irregular menstrual cycles and infertility. Small immature cysts on the ovaries disrupt hormone production, causing excessive secretion of testosterone, the male sex hormone.

Waist-Hip Ratio Good Gauge of Obesity in Elderly, Study Shows

September 04, 2009
After age 70, body mass index is less effective in identifying unhealthy weight levels, researchers say. Among the elderly, the ratio of waist size to hip size may be a better determinant of obesity than body mass index, say researchers from the University of California, Los Angeles.

For women between ages 70 and 80, every 0.1 increase in the waist-hip ratio was associated with a 28 percent increase in mortality rate, the research team reported.

Exercise May Help Maintain Weight Loss

September 04, 2009
If they continue working out, dieters can keep off pounds, study finds. For dieters, the benefits of exercise may go beyond calories burned, a new study suggests.

Exercise may ward off weight gain after dieting by reducing appetite, preventing fat cells from accumulating and by prompting the body to burn calories from fat before burning calories from carbohydrates, reducing feelings of hunger, research finds.

The study was published recently in the American Journal of Physiology .

Blueberry Drink Protects Mice From Obesity, Diabetes

September 04, 2009
Lab results indicate that juice/bacteria combination could help people, too. Blueberry juice with a little added bacteria may one day help people fight obesity and diabetes.

Canadian researchers found that juice "biotransformed" with bacteria from the fruit's skin decreased hyperglycemia in diabetic mice and protected young pre-diabetic mice from developing obesity and diabetes, according to a study appearing online in August in the International Journal of Obesity.

Study suggests officials might need to rethink strategies. Researchers are recommending that officials in the United States, United Kingdom and Australia rethink their efforts to combat obesity in children because the current strategies .

Thin Thighs Might Be Harbinger of Heart Disease

September 04, 2009
Increased risk seen in Danish study, but authors say more research is needed. Thin thighs might look good in jeans, but a new Danish study indicates they might also raise the risk of premature death and heart disease in both men and women.

That's not to say fat thighs confer any survival benefit, the researchers stressed. Rather, the study of nearly 3,000 men and women who were followed for more than 12 years found the ideal thigh measurement was in the neighborhood of 60 centimeters, about 24 inches.

Nightly Snacking May Speed Weight Gain

September 03, 2009
Mice fed high-fat diets got fatter if fed during their normal 'sleep time'
. Late-night forays to the fridge might have you packing on the pounds even faster than munching during the day does, a new mouse study suggests.

That's because the body's internal clock, or circadian rhythm, may play a role in metabolism, researchers say.

"We have found causal evidence that eating during the 'wrong' circadian time leads to weight gain in mice," said lead researcher Deanna Arble, a doctoral candidate in Northwestern University's Center for Sleep and Circadian Biology.

Scientists Turn Off 'Obesity Switch' in Mice

September 03, 2009
Deleted gene allows rodents to eat high-fat diet and stay thin, research shows. Researchers have found a gene that, when switched off, enables mice to stay slender .

Pancreatic Cancer Deaths Higher for Blacks

September 02, 2009
Accounting for risk factors made no difference in disparity, researchers find. Blacks have a significantly higher risk of dying from pancreatic cancer than whites, a new U.S. study has found.

Weight-Loss Surgery Breaks Families' 'Obesity Cycle'

September 02, 2009
Moms operated on before pregnancy had thinner children, study found. Obese mothers have children who are likely to be obese, but a new study concludes that weight-loss surgery can break the cycle.

Researchers found that women who had weight-loss surgery before becoming pregnant had children who were less likely to be heavy when compared with siblings who were born before the weight-loss surgery.

The study findings show the importance of the intrauterine environment, which seems to trump even genes and the environment in which the child is raised.

Adult Weight Gain Tied to Prostate Cancer Risk

September 01, 2009
White men risk more aggressive tumors if pounds mount up in 20s, 30s, study finds. Men who pack on excess pounds as young adults are at heightened risk of developing prostate cancer, although the risk varies by ethnic group, researchers from the University of Hawaii report.

Obesity is a risk factor for many common cancers, including colorectal cancer and breast cancer in postmenopausal women. However, whether obesity plays a role in prostate cancer risk has been unclear, researchers say.

Key Protein May Link Obesity, Diabetes, Heart Woes

September 01, 2009
Molecule in fat tissues spurs chronic inflammation that gives rise to disease, researchers say. Researchers say they know why obesity leads to diabetes and cardiovascular disease, a finding that may help experts target therapies to limit the health impact of being very overweight.

A Japanese team discovered a protein that causes ongoing, low-grade inflammation within fat tissues, which contributes to the health consequences that come with obesity, said Yuichi Oike of Kumamoto University in Japan.

The report appears in the Sept.

Mediterranean Diet May Be Best for Type 2 Diabetes

August 31, 2009
Reduced need for meds, helped some lose weight compared to low-fat diet. The Mediterranean diet, long touted as a healthy eating plan, may help people with type 2 diabetes stay off blood sugar-lowering medications, as well as help them lose weight and lower cardiovascular risk factors.

Those are the major findings from Italian researchers who found that while 70 percent of people with type 2 diabetes following a low-fat diet eventually needed diabetes medications, just 44 percent of those following the Mediterranean diet needed such drugs.

"Eating Mediterranean prevented anti-hyperglycemic drug therapy in about one-third of patients," said study author Dr.

Fat-Fighting Chemical Holds Promise

August 27, 2009
But research on 'fatostatin' is still in early stages. Researchers report that a manmade chemical appears to have the power to turn off fat production, potentially turning it into a weapon against obesity.

Fat mice injected with the chemical, known as fatostatin, didn't get fatter and developed lower cholesterol and blood sugar levels, the research team said.

But don't run out and ask your doctor for a fatostatin shot quite yet.

Regular Yoga May Improve Eating Habits

August 27, 2009
Body awareness plays a key role in weight maintenance, researchers say. Practicing yoga regularly may help your eating habits so you can maintain a healthier weight, a new study says.

Researchers at the Seattle-based Fred Hutchinson Cancer Research Center reported a link between yoga practitioners and "mindful eaters," people who were better aware of their feelings of hunger and fullness and why they ate. These mindful eaters, as opposed to those who ate regardless of hunger or to soothe anxiety or depression, tended to be less likely to be obese, the study found.

As Waistlines Widen, Brains Shrink

August 26, 2009
The obese and overweight have less neurological tissue, study finds. For every excess pound piled on the body, the brain gets a little bit smaller.

That's the message from new research that found that elderly individuals who were obese or overweight had significantly less brain tissue than individuals of normal weight.

"The brains of obese people looked 16 years older than their healthy counterparts while [those of] overweight people looked 8 years older," said UCLA neuroscientist Paul Thompson, senior author of a study published online in Human Brain Mapping.

FDA Investigating Weight-Loss Drug Over Reports of Liver Damage

August 25, 2009
32 cases have been reported since orlistat came on market in 1999 As U.S. health officials announced Monday that they are investigating the weight-loss drug orlistat for possible incidents of liver damage, experts noted the drug might not even work well enough to warrant such potential risks.

Wider Waist Boosts Asthma Risk

August 25, 2009
Even if women were of normal weight, extra fat around abdomen raised the odds, study found. Women with extra fat around their waists are more likely to develop asthma, even if they aren't overweight, a new study finds.

The California Teachers Study of more than 88,000 women found the same association between obesity and increased incidence of asthma that has been seen in other research, according to the Aug. 25 online report in the journal Thorax.

Americans Are Urged to Cut Sugar Intake

August 24, 2009
Experts recommend far fewer teaspoons a day than average person now consumes. Most American women should not consume more than 100 calories of added sugar a day, while men should limit their intake to no more than 150 calories, according to a new recommendation from the American Heart Association.

"Added sugar" refers to sugars added to foods during processing, during cooking or when a food is consumed.

The recommendation works out to about six teaspoons of added sugar a day for women and about nine teaspoons for men.

Obesity Tied to Prostate Cancer Recurrence

August 21, 2009
Leads to poor prognosis in both blacks and whites after surgery, study finds. Obesity increases the risk of prostate cancer recurrence in both black and white men, says a U.S. study that challenges previous research suggesting obesity may be more significant for black men.

Antioxidants Abound in Cereals, Popcorn, Whole-Grain Snacks

August 18, 2009
Study finds these foods contain high levels of polyphenols. Eating a bowl of your favorite cereal every day is a great source of natural antioxidants, new research shows.

Joe Vinson, a professor of chemistry at the University of Scranton, in Pennsylvania, and his team have found that nearly all whole-grain breakfast cereals and many common, grain-based snacks contain substantial amounts of polyphenols, a form of antioxidants that is thought to have major health benefits. Vinson was scheduled to present his findings Tuesday at the American Chemical Society annual meeting, held in Washington, D.

Restrictive Diet for Kids May Backfire

August 14, 2009
Children need to learn self-control to avoid becoming overweight, researchers say. Parents who try to battle the childhood obesity epidemic by forbidding their kids to eat certain foods are not going to keep them from gaining weight and may actually be making the situation worse, researchers say.

Parents play a critical role in helping children make food choices that will allow them to maintain a healthy weight, according to doctors and experts. But success depends on using the right approach.

Mediterranean Diet Plus Exercise Lowers Alzheimer's Risk

August 11, 2009
Older adults who ate healthy and remained active were protected, study finds. Eating a Mediterranean diet, which emphasizes fruits, vegetables, legumes and healthy fats, and increasing physical activity levels can reduce the risk of developing Alzheimer's disease, a new study shows.

The latest research, published in the Aug. 12 issue of the Journal of the American Medical Association, is more evidence that healthy living can help ward off cognitive decline.

How Weight Loss Helps the Heart

August 11, 2009
Study found it reversed structural abnormalities seen among the obese. Losing a lot of weight rejuvenates the physical structure of the heart, and it makes no difference whether the weight is lost by surgery or by dieting, a new British study shows.

Slide Into Debt Could Bring Wider Waistline

August 07, 2009
Less activity, 'comfort eating' might spur obesity, German study finds. Obesity rates may increase along with rising financial debt, German researchers suggest.

In their study, Eva Munster and her colleagues at the University of Mainz tracked the weight of more than 9,000 people.

They found that while 11 percent of those who were not in debt were classified as obese, a full quarter of those who were in debt met the medical criteria for obesity.

Fish Oils May Prevent and Treat Heart Disease

August 05, 2009
Review of studies involving 40,000 people points up benefits. A new review shows that the omega-3 fatty acids found in certain fish not only prevent cardiovascular disease, but may even help treat it.

"A lot of people know that omega-3 fatty acids are a good thing, but have thought of them in the area of nutritional or health foods," said study author Dr. Carl J.

Periodic Dieting May Cut Breast Cancer Risk

August 04, 2009
In lab studies, intermittent calorie restriction led to dramatic decrease in tumors. Periodically cutting calories may lower the risk of developing breast cancer better than full-time dieting, according to a new study published in Cancer Prevention Research.

Three sets of mice predisposed to developing breast tumors were put on different diets: unlimited eating, intermittently cutting calories by 25 percent, or permanently reducing caloric intake 25 percent. Those on the intermittent diet fared best, with only 9 percent developing mammary tumors compared to 35 percent of those chronically restricted and 71 percent of those that ate all they wanted.

More Kids Becoming Severely Obese

July 31, 2009
Expert urges additional programs, and coverage, for health effects. In the last 25 years, rates of severe childhood obesity in the United States have tripled, putting increasing numbers of children at risk for diabetes and heart disease, says a new study.

Researchers looked at National Health and Nutrition Survey data on 12,384 youths, ages 2 to 19 years, and found that the prevalence of severe obesity increased from 0.8 percent in the period from 1976 to 1980 to 3.

Infants Cared for in Another Home Become Heavier Toddlers

July 30, 2009
Being in own home, day-care centers didn't increase weight, study found. When infants attend day care in someone else's home, they're more likely to be heavier than average by the time they're toddlers, new research suggests.

Harvard researchers report in the August issue of Pediatrics that babies aged 6 months and younger who were cared for in someone else's home, rather than in their own home or at a day-care center, were more likely to weigh more in relation to their height at the ages of 1 and 3.

"An infant who was in child care in someone else's home in the first six months of life was 5 or so percentage points higher [on growth charts] at 1 or 3 years old than an infant who started at the same point but was cared for at home by another provider or at a center," said study author Sara Benjamin, a postdoctoral research fellow in the department of population medicine at Harvard Medical School in Boston.

Study Finds Weight-Loss Surgery Safer Than Thought

July 29, 2009
Death risk only 0.3 percent, chances of serious complications 4.3 percent. For those considering bariatric surgery to combat significant obesity, a new study suggests the risk of complications may be much lower than what has previously been reported.

The study, which looked at both gastric bypass surgery and laparoscopic adjustable gastric banding (lap-band surgery), found that the risk of death for these surgeries was 0.3 percent and the risk of a major adverse outcome was 4.

'Organic' May Not Mean Healthier

July 29, 2009
British study finds no better nutrient value than in conventionally produced foods . Food that beckons from the organic aisles of grocery stores may not be any better for you than what lines the rest of supermarket shelves.

According to a British review of studies done over the past 50 years, organic and conventionally produced foods have about the same nutrient content, suggesting that neither is better in terms of health benefits.

"We did not find any important differences in nutrient content between organically and conventionally produced foods," said study author Alan Dangour, a registered public health nutritionist with the London School of Hygiene and Tropical Medicine.

Scientists Find Way to Make 'Good' Brown Fat

July 29, 2009
Discovery could lead to ways to increase energy-burning in body, fight obesity. Boston scientists have succeeded in making brown fat out of mouse and human cells, a feat that takes scientists a step closer to victory in the fight against obesity and type 2 diabetes.

Brown fat is "good" fat because it burns energy, acting as a furnace, to help regulate body temperature by generating heat. The more of this fat you have, the leaner you tend to be.

More Can Be Done to Slow Obesity's Toll on Health

Experts

July 28, 2009
HHS Secretary Sebelius says real change begins with America's kids. Obesity in the United States now carries the hefty price tag of $147 billion per year in direct medical costs, just over 9 percent of all medical spending, experts reported at a national conference Tuesday in Washington, DC.

"To put that figure in perspective, the American Cancer Society estimates that all cancers combined cost our health care system $93 billion a year. So ending obesity would save our health care system 50 percent more dollars than curing cancer," Health and Human Services Secretary Kathleen Sebelius said Tuesday morning in prepared remarks for the "Weight of the Nation" conference, sponsored by the U.

Almost 10 Percent of U.S. Medical Costs Tied to Obesity

July 27, 2009
Only a return to healthy behaviors will bring expenditures down, experts say. Obesity in the United States now carries the hefty price tag of $147 billion per year in direct medical costs, just over 9 percent of all medical spending, experts report.

In fact, people who are obese spend almost $1,500 more each year on health care .

Unhooking the Obesity-Diabetes Connection

July 27, 2009
Understanding the link may someday lead to a cure, studies suggest. Scientists may be closer to solving a medical mystery with huge implications for personal and public health: Why obese people are prone to developing type 2 diabetes.

A series of studies appearing online July 26 in Nature Medicine suggest that inflammation within the fat tissues of heavy individuals could trigger the blood sugar disease.

What's more, each of the four completely independent studies, from two continents and three countries, showed that interfering with these immune-cell processes actually reversed diabetes in mice.

Giving Statins to Kids Provokes Debate

July 26, 2009
Cholesterol-lowering drugs may help young hearts, but long-term use raises concerns. Whether cholesterol-lowering drugs called statins should be given to children apparently depends on who you ask.

Major health associations in the United States have recommended that obese children as young as 8 years old be treated with statins if diet and lifestyle changes don't improve their health.

But the guidelines, issued by the American Academy of Pediatrics and the American Heart Association, have sparked debate in the medical community.

Snoozing May Help Women Shed Baby Weight

July 24, 2009
But avoiding postpartum sleep deprivation can be tough, experts admit. New moms who can't zip up their pre-pregnancy jeans might not be catching enough zzzs.

Getting a good night's sleep, in fact, may be just as important as diet and exercise for shedding baby weight.

One study of new mothers found that those who slept five or fewer hours a day six months after giving birth were three times as likely to hold onto those extra pounds as were women who got seven or more hours of sleep.

1 in 7 Low-Income Preschoolers Is Obese

July 23, 2009
CDC stats do show the epidemic might be slowing down among poor families. One in seven preschoolers from low-income families in the United States are considered obese, a new government report shows.

However, the same report finds that the news is not all bad: The childhood obesity epidemic does seem to be leveling off among children in this group.

Among 2- to 4-year-olds from low-income families, the prevalence of obesity increased from 12.

Eating Habits in the Obese May Echo Drug Addicts' Patterns

July 22, 2009
Sensitization could be at play, nutrition expert says. When it comes to weight control, it might not be the kind of snack that matters, but who eats it.

When researchers gave similarly "sinful" snacks to obese and non-obese women, the healthy-weight women wanted less of the treat over time, but obese women kept wanting more.

"Obese and non-obese women respond to high-energy, high-density snacks in different ways," said Jennifer Temple, lead author of the study, which appears in the August issue of the American Journal of Clinical Nutrition.

Weight-Loss Enzyme Identified

July 21, 2009
Researchers may have found a way to curb hunger, rev up energy. Reducing levels of a brain enzyme may curb appetite and boost energy, thereby helping people to control their weight, says a new study.

Prolylcarboxypeptidase (PRCP) regulates the alpha-melanocyte stimulating hormone (alpha-MSH), a body chemical that reduces hunger while revving up the body's energy levels. If PRCP enzyme is blocked, alpha-MSH levels stay high and keep appetite in check.

Studies Affirm Value of Healthy Lifestyle

July 21, 2009
Those who ate right, exercised lowered chances of cardiovascular trouble. All that heart-healthy advice about eating the right foods, exercising and losing weight pay off in real life for both men and women, two new studies show.

The reports, both originating at Brigham and Women's Hospital in Boston and published in the July 22/29 issue of the Journal of the American Medical Association, focused on different aspects of cardiovascular risk in two large groups: the 83,882 women in the second Nurses' Health Study, and the 20,900 men in the Physicians' Health Study I. Both arrived at the same conclusion: Do the right things, and you get measurable benefits.

Probiotics Supplement May Help After Gastric Bypass Surgery

July 17, 2009
In study, patients lost weight faster and avoided vitamin B deficiency Taking a probiotics supplement after gastric bypass surgery helps patients lose weight faster and avoid vitamin B deficiency, a new study finds.

Probiotics are the "good" bacteria found in yogurt and in dietary supplements that aid digestion.

The Stanford University School of Medicine study included 44 patients who had Roux-en-Y gastric bypass surgery and were randomly assigned to either a probiotics group or a control group.

Blacks Have Highest Obesity Rates in U.S.

Hispanics also show higher prevalence than whites, CDC researchers find. The obesity epidemic in the United States is hitting minorities the hardest, U.S. health officials report.

Dietary Oils May Help Some Fight Fat

July 16, 2009
Two common supplements lower body fat, build muscle in obese older women with diabetes, researchers find. For certain people, dietary oil supplements could help ward off unwanted fat, according to a new study.

Obese older women with type 2 diabetes who added safflower oil or conjugated linoleic acid (CLA) supplements to their diet either decreased their body mass index or boosted their muscle mass, researchers found.

"I don't think it's a magic bullet, but I think it could have enhancing effects," said the study's lead author, Martha A.

Number of Underweight Kids in U.S. Continues to Fall

July 15, 2009
Recent survey finds 3.3 percent of children aged 2 to 19 are below normal weight. The number of underweight children aged 2 to 19 in the United States decreased from 5.1 percent in 1971-1974 to 3.3 percent in 2003-2006, says a U.

Healthy Diet, Exercise Keeps Mind Sharp As You Age

July 14, 2009
New research finds eating healthy, moderate activity are protective. Eat right, exercise and hope that your genes don't predispose you to dementia.

That's the recipe for preserving cognitive function as you age, according to four new studies that were presented this week at the Alzheimer's Association annual meeting, in Vienna.

The findings echo other research suggesting that clean living can safeguard mental sharpness.

Walking, Biking to Work Pays Off

Excess Weight Speeds Up Osteoarthritis

July 14, 2009
Rapid loss of knee cartilage directly linked to being overweight in study. If fear of heart disease and diabetes isn't enough reason to slim down, here's another: Being overweight or obese can cause rapid deterioration of the cartilage in the knee, leading to osteoarthritis, researchers report.

Osteoarthritis usually progresses slowly, but some patients experience a more rapid progression. This is the first study to connect obesity with fast progression of the disease and cartilage loss.

Omega-3 Fatty Acid Falls Short in Alzheimer's Trials

July 13, 2009
No significant benefits seen with DHA, either in terms of prevention or treatment. Two trials that looked at whether the omega-3 fatty acid DHA might treat or prevent Alzheimer's disease have produced mixed results.

The studies were done because of "a long history of epidemiological studies that related fish consumption to cognitive function," explained Bill Thies, chief medical and scientific officer of the Alzheimer's Association. Fish is rich in DHA, but the research scheduled to be presented Sunday at the association's annual meeting in Vienna, Austria, used DHA derived from algae.

Job Stress, Economy Weighing on Americans

July 10, 2009
Worries lead to extra pounds and tip the scales toward more health risks, researcher says. Stress can keep you up at night, make you snap at your spouse and children, and make your job seem overwhelming.

If that's not bad enough, stress can also make you gain weight .

Lighter Meals May Bring Longer Life

July 09, 2009
Monkey study is best evidence yet that fewer daily calories boost lifespan. A new study that found that a lower-calorie diet slowed the aging process in monkeys could be the best proof yet that restricted diets might do the same for humans.

"The big question in aging research is, 'Will caloric restriction in species closely related to humans slow aging?'" said Richard Weindruch, senior author of a paper appearing in the July 10 issue of Science. "This is the first clear demonstration that, in a primate species, we're inducing a slowdown of the aging process .

Vegetable Amino Acid Lowers Blood Pressure

July 08, 2009
Get plenty of it in your diet, researchers say. Researchers say they have discovered that one of the most common amino acids in vegetable protein seems to lower blood pressure.

Analysis of data from an international diet study shows that a 4.72 percent higher intake of glutamic acid as a portion of total dietary protein correlates with a 1.

Fat-Cell Protein May Reduce Diabetes Risk

July 07, 2009
Higher levels of adiponectin linked in studies to lower incidence of type 2 diabetes. Higher levels of a protein created by fat cells are associated with a lessened risk of type 2 diabetes.

The protein, adiponectin, appears to have anti-inflammatory and insulin-sensitizing capabilities, according to a study published in the July 8 issue of the Journal of the American Medical Association.

"Our finding was that adiponectin is associated with a low risk of type 2 diabetes, and the effect is quite pronounced," said the study's senior author, Rob M.

Kids With Type 1 Diabetes Often Overweight

July 02, 2009
Study explores weight problems faced by youngsters with the disease. Children with type 1 diabetes are more likely to be overweight than those without the disease, increasing their risk of serious health complications, researchers say.

The finding is from a major study that explored the weight problems faced by U.S.

Obesity Rates Continue to Climb in U.S.

July 01, 2009
Eight of 10 states with highest number of obese adults are in the South, report says. The rates of adult obesity in the United States increased in 23 states during the past year and did not decrease in any state.

And the number of obese and overweight children has now climbed to 30 percent in 30 states, a troubling trend that could signal decades of weight-related health problems such as cancer, diabetes and heart disease as these children become adults.

Those are just some of the worrisome findings in an annual report on obesity in America, released Wednesday by the Trust for America's Health and the Robert Wood Johnson Foundation.

Obese Get Higher Doses of Radiation for X-Rays

June 30, 2009
Cumulative effect of that needs study, experts say. People who are overweight and obese are usually given higher-than-normal doses of radiation in order to obtain usable X-ray images, even though the long-term effects are unknown, new research contends.

"You need to get a certain amount of X-rays to go through the body in order to get an informative image, and excess weight impedes that," explained the study's lead author, Jacquelyn C. Yanch, a professor at the Massachusetts Institute of Technology in Boston.

Eating Animal Fat May Lead to Pancreatic Cancer

Added risk is tied to red meat and dairy products, study finds. Fat from red meat and dairy products can increase your risk for pancreatic cancer, researchers from the U.S. National Cancer Institute report.

Teens With Eating Disorders Benefit From Parents' Help

June 26, 2009
Research shows that recovery improves with family involvement. When a teenager has an eating disorder, it's not just the teen's problem. It's a family problem.

So, parents should join in on the treatment, a growing number of experts believe.

Obese Poor Shut Out From Weight-Loss Surgeries

June 25, 2009
Too often, they lack insurance or face roadblocks in getting the procedures, study finds. Despite having one of the highest rates of obesity in America, the poor are less likely to undergo weight loss surgery than obese people who are better off financially, new research shows.

White women with higher incomes and private health insurance were the most likely to have the surgery, according to a study to be presented Wednesday at the American Society for Metabolic & Bariatric Surgery (ASMBS) annual meeting, in Dallas.

Using data from the 2006 Nationwide Inpatient Sample, sponsored by the U.

Weight-Loss Surgery Safe, Effective Type 2 Diabetes Treatment

June 24, 2009
Research shows procedure is no more dangerous than other routine surgeries. Not only does one of the largest studies on bariatric surgery find the procedure to be as safe as other routine surgeries, two other studies confirm that it also appears to stave off diabetes for the long term.

Researchers from Duke University Medical Center analyzed data from nearly 58,000 patients included in the Bariatric Outcomes Longitudinal Database (BOLD), the largest repository of medical information on people who've undergone the weight-loss surgery.

Only about 10 percent had complications, according to the study, which was to be presented Wednesday at the annual meeting of the American Society for Metabolic and Bariatric Surgery, in Grapevine, Texas.

Bariatric Surgery Cuts Cancer Risk for Women

June 24, 2009
Finding adds to the link between obesity and cancer, experts say. Obese women who have weight-loss surgery may reduce their risk of developing cancer, but there appears to be no such benefit for men, Swedish researchers report.

Obesity is associated with an increased risk of developing many different cancers. In the United States, obesity is linked with 14 percent of cancer deaths in men and 20 percent of such deaths in women, according to background information in the study.

A Few Extra Pounds Might Bring Extra Years

Obesity While Young Boosts Pancreatic Cancer Risk

June 23, 2009
Study points to yet another reason to maintain a healthy weight. Being overweight or obese as a young adult increases the risk for pancreatic cancer, and obesity in middle age is linked with poorer survival from the disease, a new study finds.

Pancreatic cancer is the fourth leading cause of cancer-related death for men and women in the United States. As the number of people who are overweight and obese has increased in the past two decades, evidence has grown that excess body weight is a risk factor for pancreatic cancer.

Eat Well, Live Longer

June 23, 2009
Age-old advice to eat healthy pays off in longevity, study finds. If you eat a healthy diet, you're likely to live longer.

It might be trite advice, but a new study offers proof that it can make a difference in your longevity.

Those with the best diets reduced their risk of death by up to 25 percent over a 10-year follow-up, said study author Ashima Kant, a professor of nutrition at Queens College of the City University of New York.

Vinegar Might Help Keep Off Pounds

June 22, 2009
Researchers find fat-fighting properties in the lab and in mice. Not only is vinegar low in calories, but it might actually help avoid weight gain, a new study suggests.

In a study in mice, Japanese researchers fed one group a high-fat diet along with acetic acid, a main component of vinegar, for six weeks. The others were fed a high-fat diet and given water.

Obesity Greatly Raises Endometrial Cancer Risk

June 22, 2009
Odds are 22 times higher for very overweight women, study finds. Obesity is already linked to heart disease, diabetes and high blood pressure, but new research finds those extra pounds can also significantly increase a woman's risk of developing endometrial cancer, especially if she experiences early menopause.

Published in the July issue of Obstetrics & Gynecology, the study found that women with a body-mass index (BMI) greater than 35 who were under 45 at the time of their last menstrual period had a 22 times higher risk of developing endometrial cancers than their normal-weight peers.

"In this young population, the risk of endometrial cancer increased dramatically if they had a BMI greater than 25," said study author Cheryll C.

Common Weight-Loss Surgery May Double Risk of Kidney Stones

June 22, 2009
Roux-en-Y gastric bypass linked to small increased chances of trouble, research shows. A popular weight-loss surgery may double the risk of kidney stones, though the actual odds are still relatively slight, a new study suggests.

Having Roux-en-Y, the most common type of gastric bypass surgery, may result in a person having an 8 percent chance of developing the urinary tract disorder usually caused by oxalate in food combining with calcium or other chemicals to form clusters of crystals. These stones can be very painful to pass through normal urination and sometimes require surgery or other medical intervention to treat.

Does Location Affect Kids' Weight?

June 19, 2009
Study refutes belief that living near fast-food joints makes children fat. Living near a fast-food outlet doesn't make children fat, nor does living near a supermarket stocked with fresh fruits and vegetables make them thin, new research shows.

The study by Indiana University-Purdue University Indianapolis researchers examined a decade of data on more than 60,000 children aged 3 to 18. They compared the children's weights before and after fast-food outlets or supermarkets opened near their homes.

Green Tea Component May Slow Prostate Cancer

Heart Association Warns of Surgery Risks in Obese

June 15, 2009
Complications may include wound infections, heart problems, new advisory says. Severely obese people undergoing surgery are at greater risk of heart problems, wound infections, prolonged hospital stays and other complications, according to a Scientific Advisory from the American Heart Association.

Yet many cardiologists, surgeons, anesthesiologists and other health-care providers underestimate the seriousness of the risks, particularly to the heart, the association warns.

About 3 to 4 percent of Americans are considered severely obese, defined as having a body mass index of 40 or higher, according to information in a news release from the association.

Diabetes Drug Byetta May Aid Weight Loss in Obese Patients

The study participants included 641 people in the United States, Canada and the United Kingdom, aged 65 to 91, who were overweight and were long-term (five years or more) survivors of breast, prostate and colorectal cancer. Some were assigned to a control group, while others were assigned to a 12-month intervention program that included telephone counseling, mailed materials promoting exercise, improved diet, and modest weight loss.

Frequent Feedings May Be Making Babies Fat

May 12, 2009
Moms might not notice signs that infants are full, study concludes. Mothers who fail to notice signs that their babies are full tend to overfeed them, resulting in excess weight gain when the infants are between 6 months and a year old, a new study has found.

The finding comes from a study by Rutgers University researchers of 96 low-income black and Hispanic mothers who formula-fed their babies. The mothers recorded information about their babies' feedings, and researchers visited the mothers when the babies were 3, 6 and 12 months old to observe feedings and to weigh the babies.

Supportive Weigh-In Program Keeps Pounds Off

May 11, 2009
Women maintained losses with biweekly checks and counseling, study finds. The struggle to keep the pounds off that one has just lost can be aided effectively and inexpensively with a simple five-minute weigh-in with a nurse every couple of weeks.

New Zealand researchers, writing in the medical journal CMAJ, found that the biweekly weigh-in, along with a call from the same nurse during the intervening weeks, helped women maintain their weight loss as well as a more expensive and intensive program using dietitians and exercise specialists.

The study, which followed most of 200 women for two years, randomly divided the participants into one group that had the weigh-ins and supportive phones calls with a nurse and another that followed a more comprehensive diabetes prevention program that included regular exercise programs.

DASH Diet Has Extra Benefits for Women's Health

May 11, 2009
Diet to lower blood pressure may also cut risk of heart failure, research shows. A diet that prevents and lowers high blood pressure has been linked to a reduced risk of heart failure in women, a new study finds.

"The Dietary Approaches to Stop Hypertension [DASH] diet may contribute to prevention of heart failure in some cases because it effectively reduced blood pressure and low-density lipoprotein (LDL, or "bad") cholesterol levels in clinical trials," wrote Emily B. Levitan, of Beth Israel Deaconess Medical Center in Boston, and colleagues.

Folic Acid Might Offer Allergy Relief

April 30, 2009
But use of supplements should await further study, expert says. Folic acid, also known an vitamin B9, might help treat allergies and asthma, suggests a new study.

Researchers from the Johns Hopkins Children's Center reviewed the medical records of more than 8,000 people, ages 2 to 85, to track the effect of folic acid levels on respiratory and allergic symptoms and on levels of IgE antibodies, the immune system markers that increase in response to an allergen.

They found that people with higher blood levels of folic acid had fewer IgE antibodies, fewer reported allergies and less wheezing and were less likely to develop asthma.

Obesity Surgery Complications on the Decline

No Verdict Yet on Grape Seed Extract vs. Breast Cancer

April 23, 2009
Researchers plan more controlled study at different dosages. More research is needed to determine whether grape seed extract lowers hormone levels in postmenopausal women and provides protection against breast cancer, say researchers at the City of Hope cancer center in Duarte, Calif.

Because studies have suggested that grape seed extract inhibits aromatase, an enzyme that helps in estrogen production, the researchers looked at whether grape seed extract supplements could lower hormone levels in postmenopausal women.

What they found was a dramatic and sustained decrease in one patient with high baseline estrogen levels.

Soy May Not Lead to Denser Breasts

April 22, 2009
Study finds no link to condition that can increase cancer risk. Soy isoflavones don't increase breast density, a new study finds.

That's good news because it's believed that increased breast density is associated with a higher risk of breast cancer. A number of studies have suggested that dietary factors, including isoflavones (estrogen-like plant compounds) might increase breast density.

Staying Slim Is Good for the Environment

April 22, 2009
Sustaining heavier people produces more greenhouse gases, researchers say. Watching your weight does more than protect your health. It also may help fight climate change.

Researchers at the London School of Hygiene & Tropical Medicine say that because food production is a major contributor to greenhouse gases, a lean population, such as in Vietnam, consumes about 20 percent less food and produces fewer greenhouse gases than a population in which 40 percent of people are obese, a rate close to that of the United States.

Obesity May Hide Fetal Abnormalities on Ultrasounds

April 22, 2009
As a woman's weight rises, so does risk of inaccurate reading, study shows. Overweight and obese women are less likely to receive an accurate reading from ultrasound screenings aimed at identifying fetal abnormalities, new research reveals.

Such screenings also seem to be less effective among women who are diabetic prior to their pregnancy.

"We were asking the question, 'Are birth defects less likely to be detectable with prenatal ultrasound in women who are overweight or obese, compared with women of normal body-mass index,'" explained study author Dr.

Fructose-Sweetened Drinks Up Metabolic Syndrome Risk

April 20, 2009
But glucose-based beverages may not have same impact, study finds. Fructose-sweetened soft drinks and other beverages can have a negative effect on the body's sensitivity to insulin and its ability to handle fats, increasing the risk of heart attack and stroke, a new study suggests.

But glucose-sweetened beverages don't have that kind of impact, the study found.

The research included overweight and obese volunteers who for 10 weeks drank either fructose- or glucose-sweetened beverages that supplied 25 percent of their energy needs.

Study Rates Breast Cancer Risks Among Races

April 20, 2009
Researchers find white and black women share certain risks; other factors are more distinctive. White women and black women in the United States share certain breast cancer risk factors but appear to have distinctive risk factors as well, a new study shows.

Researchers conducting on ongoing study have so far enrolled 1,826 white and 360 black women with breast cancer, and 1,766 healthy white and 240 healthy black women. The initial data shows that lack of physical activity and being overweight or obese are associated with a 20 percent increased risk of breast cancer in both groups of women.

Review Confirms Links Between Diet, Heart Health

April 13, 2009
Vegetables, nuts, and 'Mediterranean' fare most beneficial, researchers find. Vegetables, nuts and the so-called "Mediterranean" diet are heart-friendly, while trans fats and foods with a high glycemic index can harm your heart, say researchers who reviewed 189 studies published between 1950 and 2007.

The studies included 146 prospective cohort studies (which examined past habits of participants) and 43 randomized controlled trials (volunteers were randomly assigned to consume a certain kind of diet).

"The relationship between dietary factors and coronary heart disease has been a major focus of health research for almost half a century," wrote Andrew Mente, of the Population Health Research Institute, and colleagues.

More U.S. Kids Taking Diabetes, Blood Pressure Drugs

April 06, 2009
Prescriptions rose by more than 15 percent in 3 years, researchers say The number of American children and teens taking drugs to lower blood pressure and control diabetes has risen significantly since 2004, according to a new study.

The study is one of several reports on childhood obesity in the April issue of Archives of Pediatrics & Adolescent Medicine.

In the first report, researchers at CVS Caremark, a large supplier of medications to people with health insurance, used the company's drug database to track prescriptions filled on behalf of children and adolescents.

Pot Belly Boosts Risk for Restless Legs Syndrome

April 06, 2009
Obesity may alter nervous system, triggering the movement disorder, researchers say. Having a big belly or being obese appears to increase the risk for restless legs syndrome (RLS), a new study finds.

Some 5 percent to 10 percent of adults in the United States have RLS, a disorder that causes people to feel a compelling need to move their legs, especially when they're lying down. The condition can have a substantial impact on sleep, daily activities and quality of life, researchers say.

Obesity Boosts Gum Disease Risk

April 05, 2009
Experts say common denominator may be inflammation, suggest heart-healthy diet. Obese adults are at higher risk of gum disease than are normal-weight people, a new study finds.

For many years, researchers have been trying to determine the link between gum disease and cardiovascular risk, said study author Monik Jimenez, a doctoral candidate at the Harvard School of Public Health.

To explore the possible connection between excess weight and periodontal problems, Jimenez and her colleagues analyzed data from nearly 37,000 men who participated in the Health Professionals Follow-Up Study.

TV Time May Not Be Benign

April 03, 2009
Behavioral problems, obesity more likely in kids who watch 2 hours-plus a day. Parking the kids in front of the TV might seem like an easy way to grab a couple of minutes to relax after work or make dinner, but too much TV time is definitely not a good thing.

Researchers have found that, along with significantly increasing the risk of childhood obesity, the likelihood of behavioral problems also goes up when kids watch more than two hours a day of TV.

"Sustained TV watching has a negative effect on behavior and social skills," said Carla Weidman, a psychologist in the child development unit at Children's Hospital of Pittsburgh.

Fewer Sugary Drinks Key to Weight Loss

April 02, 2009
Cutting down on sodas, other sweet beverages may work better than eating less, study finds. When it comes to losing weight, cutting back on the calories in sugar-sweetened drinks, rather than food, may be most important.

Antioxidant-Rich Foods Lose Nutritional Luster Over Time

April 02, 2009
Studies found levels of good compounds dropped after 6 months. For those who swear by antioxidant-rich food and drink, two new studies show those health benefits can wane if the products are stored for too long a time.

The findings focus specifically on how well antioxidant activity holds up in commercially available green tea bags and olive oil when stored unopened and unexposed to light or moisture. And, in each case, the research revealed that steep drops in antioxidant activity take place within the first six months.

The Dark Side of Vegetarianism

April 01, 2009
For some teens and young adults, otherwise healthy diet may be concealing eating disorders. Despite its proven health benefits, a vegetarian diet might in fact be masking an underlying eating disorder, new research suggests.

The study, in the April issue of the Journal of the American Dietetic Association, found that twice as many teens and nearly double the number of young adults who had been vegetarians reported having used unhealthy means to control their weight, compared with those who had never been vegetarians. Those means included using diet pills, laxatives and diuretics and inducing vomiting to control weight.

School PE Programs Don't Lower Child Obesity

March 30, 2009
But they do boost fitness and are still valuable, study finds. Physical fitness programs in schools improve many aspects of children's health, but they don't appear to combat obesity, a new study in the Canadian medical publication CMAJ shows.

Improvements in blood pressure, muscle mass, bone mineral density, lung capacity and flexibility were some of the benefits experienced by the more than 18,000 students participating in "physical activity interventions" at their schools; however, the program's did not noticeably lower the children's body-mass index (BMI) .

Omega-3 Fatty Acids Guard Against Advanced Prostate Cancer

March 24, 2009
Even men genetically predisposed to disease benefit from eating fish, study finds. Omega-3 fatty acids could help protect men against advanced prostate cancer, researchers report.

Eating fish at least once a week may reduce the risk of developing advanced prostate cancer even if one is genetically predisposed to developing the disease, but more work is needed to see if the association is real, the researchers said.

"Eating a healthy diet that includes dark fish and other sources of long-chain omega-3 fatty acids may decrease risk of more advanced prostate cancer even if one has a cox-2 genetic predisposition to the disease," said lead researcher John S.

Many Americans Fear Being Diagnosed With Diabetes

March 24, 2009
But most do little to reduce risks of getting blood sugar disease, survey finds. More than half of Americans fear developing diabetes, but many continue the unhealthy behaviors that boost their odds of getting the blood sugar disease, a new survey shows.

"I think people continue the risky behaviors because they think, 'It's not going to happen to me,'" said Dr. Richard M.

High Blood Fat Levels Common in Americans

March 23, 2009
And those fats, called triglycerides, may contribute to heart risk, study says. Many Americans have higher-than-recommended levels of the blood fats called triglycerides, and most aren't making the lifestyle changes necessary to bring those levels down, a study finds.

"Clearly, the focus in this country has been on cholesterol levels," said Dr. Earl S.

Protein From Yellow Peas May Lower Blood Pressure

Most New EMS Recruits Overweight or Obese

March 20, 2009
Massachusetts finding has troubling implications for public safety, experts say. More than 75 percent of candidates for fire and ambulance services in Massachusetts are either overweight or obese, a situation that has major consequences for public health and safety, researchers say.

"First, cardiovascular disease and musculoskeletal injury are important causes of [disability and death] in emergency responders, and excess body fat is associated with higher risk for both. Second, because of the nature of emergency response work, any health condition suddenly incapacitating an emergency responder also potentially compromises the safety of his or her co-workers and the community," lead author Antonios Tsismenakis, a second-year medical student at Boston University School of Medicine, said in a news release.

It's similar to smoking when it comes to effect on longevity, researchers note. Being obese can shorten your life, a new study shows.

"Moderate obesity typically shortens life span by about three years," said researcher Gary Whitlock, from the Clinical Trial Service Unit at the University of Oxford in the United Kingdom. "By moderate obesity, I mean weighing about a third more than is ideal, which for most people would mean being about 50 or 60 pounds overweight.

Weight Loss Might Not Curb Knee Arthritis

March 13, 2009
Obesity boosts risk, but weight has no overall effect on progression, study says. Losing weight may not help prevent the progression of knee osteoarthritis, a new study suggests.

Researchers looked at more than 2,600 people with the knee ailment who were at high risk for the condition because they were overweight or obese or had other risk factors such as knee pain or previous knee injuries. Participants were given a physical examination and hip bone mineral test and had X-rays taken of both legs at the start of the study and of their knees again after 30 months.

Aging Baby Boomers May Swamp Cardiac Care

March 13, 2009
'Diabesity' renders them more prone to heart attacks than their predecessors, researchers say. Baby boomers are not in good shape, even when compared with their counterparts 10 or 20 years ago, researchers warn.

According to a new study, more aging boomers are being hospitalized for heart attacks now than people their age were a generation ago, and the increase in cases could place a big burden on cardiac care wards nationwide.

But on the upside, improvements in medical care may allow more people from this generation to recover and leave the hospital after a heart attack, the researchers say.

Kids Who Live Near Green Spaces Seem to Walk More

March 12, 2009
Experts urge urban planners to heed study's finding and help fight obesity. Living close to parks and other play areas may keep children more active and help combat the continued increase in childhood obesity, Canadian researchers report.

For every park found within a half-mile of home, a girl's likelihood of walking to school doubled and a boy's odds of taking part in leisure walking increased by 60 percent, according to the findings, scheduled to be presented at an American Heart Association conference in Palm Harbor, Fla.

"There was a strong association between walking and the number of nearby public open recreational spaces, including neighborhood parks, playgrounds and sports fields," the study's lead author, Tracie A.

Folic Acid Supplements Raise Prostate Cancer Risk

March 10, 2009
But 10-year study also showed having enough folate in diet might offer protection. A 10-year study has found that men who took folic acid supplements faced more than twice the risk of prostate cancer as those who didn't take the supplements.

But the incidence of prostate cancer in the study was slightly lower in men who simply got adequate amounts of folate in their diet, according to a report in the March 10 online issue of the Journal of the National Cancer Institute.

"What we think is that perhaps too much folate is not necessarily beneficial, whereas adequate levels may be," said study leader Jan Figueiredo, an assistant professor of preventive medicine at the University of Southern California.

Church-Based Weight Plan Peels Off Pounds for Blacks

March 10, 2009
Members dropped 5% of body weight and sustained it for 6 months, study finds. A 12-week church-based weight loss program helped many overweight/obese blacks lose 5 percent or more of their body weight, and most of them maintained their weight loss for at least six months.

Bias Against Obesity Is Found Among Future Dietitians

March 05, 2009
Attitude could affect care patients might get, experts warn. Just 2 percent of those training to be dietitians have positive or neutral attitudes toward people who are obese, and the rest are moderately biased against their prospective patients, a new study has found.

"Essentially, this shows that future dieticians are not immune to weight bias, and there are negative attitudes toward obese patients that may have a negative impact on the quality of care," said Rebecca Puhl, the study's lead author and the director of research and stigma initiatives at Yale University's Rudd Center for Food Policy and Obesity.

Most of the almost 200 dietetic students who participated in the study had pejorative views about the attractiveness, self-control, overeating, insecurity and self-esteem of people who are obese.

Insulin resistance, the progression of liver disease, and living a less-than-active life were all found to be associated with the common breathing disorder, regardless of people's weight, according to reports published in the February issue of the American Journal of Respiratory and Critical Care Medicine.

A John Hopkins University study found a strong tie between insulin resistance .

Heavy Smoking as Teenager Might Add Pounds Later

January 22, 2009
Study finds an association, but some experts are skeptical. A surprising Finnish study casts doubts on the common assumption smokers have that their unhealthy habit helps keep them thin.

Specifically, the researchers found that teens who smoke heavily were more likely to grow up to be fat.

There's still no evidence that cigarettes directly cause obesity, but "this is one more thing people should take into account when they consider their smoking habits," said study author Dr.

Supplement Hampers Thyroid Cancer Treatment

January 21, 2009
Iodine from kelp in dietary aid compromised therapy, researchers say. People taking dietary supplements need to be careful that those don't interfere with any medical treatments they might be getting, a new report emphasizes.

The case in point was a 55-year-old man being treated for thyroid cancer who was supposed to be on a low-iodine diet as part of his treatment, but his levels of iodine continued to increase. The researchers found that a selenium supplement he was taking contained kelp, which is a rich source of iodine and significantly increased his iodine levels.

Why Saying No to Foods May Be Harder for Women

January 20, 2009
Gender differences might be explained by hormones and evolution, study finds.Why Women Have a Tougher Time Shunning Favorite Foods New research on the brain suggests that women unconsciously have a tougher time resisting their favorite foods than men do.

"This gives us another piece to put into this puzzle," said Dr. Gene-Jack Wang, the study's author, who speculated that women may have more trouble saying no to food because they sometimes have to eat for two.

Low-Cost Strategies to Maintain Health in Hard Times

January 19, 2009
Staying fit doesn't have to break the bank, experts say. Everyone needs to make sacrifices during hard economic times, but you don't have to shortchange your health.

Experts with the Dana-Farber Cancer Institute in Boston say people can live healthy and cut their risk of cancer without breaking the bank by following several free and low-cost strategies.



Get moving.

Preschool Lunch Doesn't Always Pack Nutritious Punch

January 19, 2009
Study finds meals from home often lack fruits, veggies, whole grains. When parents pack their preschoolers' lunches, they may be sacrificing nutrition by giving the children food they like.

That's one of the conclusions of a new study in the January issue of the Journal of the American Dietetic Association. The study also found that 71 percent of packed lunches didn't have enough fruits and vegetables, and that one in four preschool tots didn't get enough milk with lunch.

Diet, Exercise Cuts Kids' Risk for Metabolic Syndrome

January 13, 2009
Preventing obesity boosts blood vessel function even without weight loss, study says. Components of metabolic syndrome that appear in children should be treated by doctors who also must encourage them to improve their diet and exercise routines, a new report says.

Metabolic syndrome in adults occurs when they have at least three risk factors from among abdominal obesity (waist circumference more than 35 inches for women; 40 inches for men); low HDL ("good") cholesterol; high triglycerides; high fasting glucose; and high blood pressure.

Although sometimes difficult to diagnosis in children, similar clustering can appear in childhood.

Sodium, Potassium Intake Tied to Heart Disease

January 12, 2009
Study finds 24% greater risk per unit increase in salt-to-mineral ratio. Too much sodium and too little potassium in one's diet may increase one's risk of cardiovascular disease, a new study suggests.

The findings, based on a long-term analysis by the U.S.

Americans Consuming More Sugary Beverages

January 09, 2009
Adults gulping an average of 300 calories every day, study finds. If you're like many Americans, soda and coffee drinks have become a staple of your daily diet.

But the findings from a new study may make you drop that super-sized, sweetened beverage.

Published in the January issue of The American Journal of Clinical Nutrition, the research found that people are now drinking almost 50 additional calories of sweetened beverages daily compared to two decades ago, for an average of about 300 calories daily coming from such drinks.

Parents Not Best Barometer of Kid's Eating, Exercise Habits

January 09, 2009
Survey found mismatch between perception, reality. Parents may not always be the best barometer of their child's eating and exercise habits, a new study shows.

Researchers reported in the January/February issue of Journal of Nutrition Education and Behavior that mothers of preschool-aged children thought their kids ate and exercised well, while those with older children did not. But when the children and their actual habits were examined more closely, there was little difference between the two age groups.

Doctors Urged to Screen Diabetics for Sleep Apnea

January 08, 2009
Treatment may reduce risk of cardiovascular disease. Here's a wake-up call to the millions of American men and women with type 2 diabetes: Snoring at night or nodding off during the day may be symptoms of obstructive sleep apnea, a potentially life-threatening problem affecting one out of three diabetics.

Based on strong preliminary evidence linking the two disorders, global health experts are encouraging physicians to assess their diabetic patients for sleep apnea symptoms and to screen sleep apnea sufferers for metabolic disease. The recommendation comes from the International Diabetes Federation (IDF) Task Force on Epidemiology and Prevention.

Brains of Bulimia Patients Wired Differently

January 06, 2009
Study found regions related to impulse control were less active. Brain circuitry involved in regulating impulsive behavior seems to be less active in women suffering from the eating disorder known as bulimia nervosa.

The frontostriatal regulatory circuits implicated in this study are mediated by both the neurotransmitter dopamine and the neurotransmitter serotonin.

So far, serotonin has been widely implicated in bulimia, which is often treated with antidepressants known as selective serotonin reuptake inhibitors (SSRIs).

It Pays to Eat Less as You Age

January 06, 2009
Cutting calories can cut down on pounds in middle age, study says. Eat less, weigh less.

While it may sound painfully obvious, nutrition experts have been divided over whether cutting calories leads to long-term weight loss, because the practice can sometimes boomerang, triggering binge eating and weight gain.

But, new research suggests that eating less can pay big dividends, particularly as you age.

Researchers Report Progress in Fight Against Fat

January 06, 2009
Two drugs and a genetic variation are focus of promising studies. Researchers are reporting in two new studies that they seem to be moving closer to the holy grail of new treatments for obesity.

In one study, scientists managed to coax the brains of obese mice to process a hormone called leptin that helps control appetite.

"It's very exciting, because leptin was being talked about as a dead end, that it will never work," said study co-author Dr.

Obesity Linked to Ovarian Cancer

January 05, 2009
Excess estrogen may contribute to malignancy, study suggests. Obese postmenopausal women who have never used hormone replacement therapy may face an increased risk of ovarian cancer, compared to normal-weight women, a new study suggests.

Interestingly, obese women who have used hormone replacement therapy (HRT) for symptoms of menopause may not face increased risk for this type of malignancy.

The study findings are published in the Feb.

Prenatal Nutrition, Postnatal Allergy Protection

January 04, 2009
Certain foods consumed during pregnancy might protect against asthma and eczema. An apple a day while you're pregnant may indeed keep the doctor away. But the real beneficiary could be your unborn child.

Recent research suggests that when moms-to-be eat apples during pregnancy, their offspring have lower rates of asthma.

High Insulin May Boost Odds of Breast Cancer

December 30, 2008
Finding may clarify the disease's connection to obesity. Women with high levels of insulin in their blood appear to be more likely to develop breast cancer than those with lower insulin levels.

And that might be the link between obesity and breast cancer, say researchers from the Albert Einstein College of Medicine in New York City. High insulin levels have already been associated with obesity.

America Losing the Fight With Type 2 Diabetes

December 30, 2008
Yet simple lifestyle changes can make all the difference. The type 2 diabetes epidemic that continues to sweep across the United States has left an estimated 24 million Americans struggling with the disease, up more than 3 million people since 2005.

And, of course, with the epidemic comes the wave of illnesses and disabilities brought on by diabetes .

Gastric Bypass Halts Diabetes in Obese Teens

January 05, 2009
Surgery could help them avoid long-term complications of blood sugar disease, scientists say. Obese teenagers who have gastric bypass surgery not only lose weight but see their type 2 diabetes disappear, a new study finds.

Also called bariatric surgery, the procedure works by limiting the size of the stomach and thereby reducing the amount of food one can eat. In this study, researchers used the Lapband method, which involves placing an adjustable band to block off most of the stomach.

Fish Oil's Benefits Remain Elusive

December 24, 2008
Review finds it may cut cardiac mortality but not help those with heart rhythm problems. Consuming fish oil appears to reduce the chance of death from heart problems, but it may not help those with heart rhythm problems, a new analysis shows.

The conclusions are based on a Canadian review of dozens of fish oil studies involving more than 30,000 people. The study, by a team at the University of Alberta, in Edmonton, was published in the online edition of BMJ.

FDA Warns About Weight Loss Products

December 23, 2008
Agency says more than 2 dozen contain dangerous ingredients not listed on label. The U.S. Food and Drug Administration warned consumers Monday to avoid more than two dozen products marketed for weight loss because they contain undeclared ingredients that could pose serious health risks.

Even a Little Overweight, Inactivity Hurts the Heart

December 22, 2008
Large study finds increased risk of heart failure Even a few extra pounds and just a little inactivity increased the risk of heart failure in a major study of American doctors.

"What this study shows is that even overweight men who are not obese have an increase in heart failure risk," said Dr. Satish Kenchaiah, lead author of a report on the finding in the Dec.

Eating Strategies for Healthier Holiday Parties

December 21, 2008
Easy-to-follow tips can take the guilt, and the calories, out of the equation. Rather than worry about gaining or losing weight during the holidays, focus on simply keeping steady on the scales by following some simple healthy eating strategies, one dietitian says.

"Trying to diet during the holidays is setting yourself up for failure and personal torture," Jennifer Ventrelle, clinical nutritionist and registered dietitian at Rush University Medical Center, said in a news release issued by the Chicago facility. "Set an achievable goal: to maintain your weight through the holiday season.

For the Obese, Holiday Tables Serve Platefuls of Doubt

December 20, 2008
But fear of social pressures can be overcome with honest approach to food, expert says. The holiday season can be especially difficult for overweight or obese people as they struggle to control their eating habits and cope with widely held misconceptions, according to a Duke University expert.

"Social situations make people feel self-conscious about what they wear and what they eat to the point where they feel they're being judged for every morsel that touches their lips," Martin Binks, director of behavioral health at the Duke Diet and Fitness Center, said in a university news release.

"Some of the popular misconceptions about obesity are that people bring it on themselves, and that they look forward to the holidays so they can eat more," he said.

Quitting Smoking Tougher on Women

December 19, 2008
If pounds add up, some get nervous and start puffing again, study says. Women who quit smoking tend to suffer more intense withdrawal symptoms, such as depression, anxiety, poor concentration and weight gain, a new report says.

Whether men or women tend to be more successful at ending their cigarette habit was not determined by the report, published in the December issue of Mayo Clinic Women's HealthSource. But the study noted that after gaining an average of 5 to 10 pounds during withdrawal, some women start smoking again.

Limiting School Snacks Boosts Fruit, Veggie Consumption

December 19, 2008
The increase, while modest, was significant, study finds. Restricting the availability of unhealthy snacks in elementary schools led to a small increase in fruit and vegetable consumption among fifth-graders, a new study found.

The roughly 3 percent increase in fruit and vegetable intake among those children in schools that restricted the availability of snacks was still significant, said study co-author Edward A. Frongillo, chairman of the University of South Carolina's department of health promotion, education and behavior.

Childhood Obesity May Cause Thyroid Problems

December 18, 2008
Finding suggests low-grade inflammation changes gland's structure. Childhood obesity may alter the structure and function of the thyroid gland, an organ in the neck that releases hormones crucial to metabolism.

Studies have found that thyroid disorders can lead to obesity, but a new Italian study suggests that obesity may cause thyroid dysfunction in some cases.

"Our study shows that alterations in thyroid function and structure are common in obese children, and we may have uncovered the link," study author Dr.

Study Finds Molecular Link Between Obesity, Hypertension

December 17, 2008
Signaling through the melanocortin-4 receptor controls blood pressure, study shows. Most people know that obese individuals tend to have high blood pressure, but now British researchers have identified the molecular pathway that could explain that link.

In findings published in the Dec. 17 online issue of the New England Journal of Medicine, Sadaf Farooqi, of the University of Cambridge, and her colleagues demonstrated that signaling through the melanocortin-4 receptor (MC4R) helps to regulate blood pressure in humans.

Strict Blood Sugar Lowering Won't Ease Diabetes Heart Risk

December 17, 2008
Blood pressure, cholesterol control may be type 2 diabetics' best bet, researchers say. Intensive lowering of blood sugar in people with poorly controlled type 2 diabetes does not have a significant effect on reducing cardiovascular events, such as heart attack and stroke, a new study finds.

"You can decrease cardiovascular events in patients with type 2 diabetes by good treatment of lipids [cholesterol], blood pressure and other cardiovascular risk factors," noted lead researcher Dr. William Duckworth, from the Phoenix Veterans Affairs Health Care Center in Arizona.

'Mediterranean'-Style Diet Best for Blood Sugar Control

December 17, 2008
Another study finds type 2 diabetes increases cancer death risk. Chowing down on lentil soup and pasta seems to be the way to go if you have type 2 diabetes.

A new study found that a diet of "low-glycemic foods" .

Snorers Burn More Calories During the Day

December 16, 2008
But study shows it doesn't offset extra weight that often accompanies the condition. People who snore burn more calories when they're resting during the day than people who sleep quietly through the night, new research shows.

However, the calorie expenditure doesn't seem to be enough to balance the extra weight that often accompanies the condition, also known as sleep apnea.

"There are a lot of other factors that are going on that lead to a net increase in body weight," said Dr.

Deaths From Heart Disease, Stroke Down 30%

December 15, 2008
Medical advances, not lifestyle changes, are source of the improvement, AHA says. U.S. death rates for heart disease and stroke have dropped by about 30 percent since 1999, according to the latest American Heart Association statistics.

Obesity-Related Hormone Tied to Psoriasis

December 15, 2008
Higher leptin levels play role in immune, inflammatory processes, study says. People with psoriasis have higher levels of the obesity-related hormone leptin than those without psoriasis, new research shows.

The Taiwanese study included 77 psoriasis patients and a control group of 81 people without the skin condition.

The researchers gathered health information about the participants and analyzed blood samples for levels of leptin, which helps control food intake, body weight and fat stores.

Genetic Variants Tied to Obesity

December 15, 2008
Findings add to knowledge about appetite regulation among people. Certain people just may be destined to be obese, based on the discovery of six additional genetic variants tied to people with higher body mass index, a new study says.

The study by an international consortium, published online Dec. 14 in Nature Genetics, adds to previous research that linked two other genetic variants to obesity.

Gastric Bypass Success Sparks Debate

December 14, 2008
Should older people and those with diabetes have the weight-loss surgery? Recent studies showing that gastric bypass surgery extends the lives of obese patients is forcing surgeons to make tough decisions about who should go under the knife and who shouldn't.

Internists, cardiologists and endocrinologists, more than ever, are referring patients who traditionally haven't been candidates for the weight-loss surgery, also called bariatric surgery.

"I am being asked to operate on 78-year-olds with co-morbidities of heart disease and diabetes," said Dr.

Experimental Weight-Loss Pill Passes Early Test

December 13, 2008
People lost significant weight; no side effects on heart seen, study says. Researchers are hoping that an experimental new weight-loss drug will prove to be a valuable new weapon in the crusade against obesity.

In recently released phase 2 trials, the drug, known as lorcaserin, resulted in substantial weight loss in obese men and women.

"Lorcaserin is a completely novel mechanism and we think it can bring very robust weight loss.

Fruits and Veggies May Strengthen Bones

December 12, 2008
Could join calcium and vitamin D in fight against osteoporosis, study finds. Eating lots of protein and cereal grains causes excess acid production in the body, experts say, which could increase calcium excretion and result in weakened bones.

However, a new study finds that boosting alkali levels with a pill or by consuming plenty of fruits and vegetables can strengthen bones.

The study included 171 men and women aged 50 and older who were randomly assigned to receive a placebo or doses of either potassium bicarbonate, sodium bicarbonate, or potassium chloride for three months.

2 Markers Predict Survival Odds in Colon Cancer Patients

December 11, 2008
One protein was protective, the other not, researchers found. Blood levels of two insulin-related proteins are able to predict which patients with colon cancer are most likely to die of their disease, new research suggests.

Insulin ushers blood sugar out of the bloodstream and into cells. The hormone tends to work less efficiently in people who are obese, eat heavily and don't exercise, a condition which can lead to diabetes, heart disease and other conditions.

Fast Heart Rate Warns of Obesity, Diabetes

December 11, 2008
And those conditions take toll on the heart, study says. A too-fast heartbeat in early adulthood is a warning sign for increased risk of cardiovascular problems decades later on, a Japanese study suggests.

The study of 614 residents of a rural farming community in southwestern Japan found that a heart rate greater than 80 beats a minute during a first examination in 1979 predicted the development of obesity and diabetes, which contribute to heart problems.

The findings, from Kurume University School of Medicine, were published online Dec.

Gene May Make Kids Crave Junk Food

December 10, 2008
Some are genetically driven to eat more calories, study suggests. Some people may be genetically driven to seek out more calorie-dense foods, a new study suggests.

In the Dec. 11 issue of the New England Journal of Medicine, British researchers report that children with a particular gene variant tend to eat more energy-dense foods, which means food with more calories per weight.

Obese Kids More Prone to Limb Injuries in Car Crashes

December 10, 2008
Weaker bones from poor diet, less exercise may be to blame, experts say. During a car crash, American children who are overweight or obese face twice the risk of injury to their arms, legs and feet that normal-weight children do, a new study reveals.

The findings come from a national sample of boys and girls between the ages of 9 and 15.

"Ultimately, motor vehicle crashes are the leading cause of death for all kids in the age range of the study," noted study author Keshia M.

Study Suggests Sugar May Be Addictive

December 10, 2008
Finding might yield new insights into eating disorders, experts say. Science is verifying what many overeaters have suspected for a long time: sugar can be addictive.

In fact, the sweetener seems to prompt the same chemical changes in the brain seen in people who abuse drugs such as cocaine and heroin.

The findings were to be presented Wednesday at the American College of Neuropsychopharmacology's annual meeting, in Nashville.

Obesity is a Family Affair

December 10, 2008
Skipped meals, too much TV time end up harming kids, study finds. Although genetics likely play a role in whether or not someone becomes overweight or obese, a family's lifestyle also has a major impact on the chances of a teenager winding up overweight, a new study shows.

Adolescents tended to be heavier in families that frequently missed meals or spent several hours a day in front of the TV or video games, researchers report in a special issue of the American Journal of Sociology.

"My study finds that weight runs in families, but it's not just because of genetics.

Money May Lure People to Lose Weight

December 09, 2008
But study found some pounds return after incentives end. Putting money in people's pockets can help persuade them to shed fat, suggest American researchers who created two incentive-based approaches for losing weight.

Anemia Rates Down for U.S. Women and Children

December 08, 2008
But they remain disproportionately high for minority women, study finds. Fewer American women and children are developing anemia, according to a new U.S. Centers for Disease Control and Prevention report.

11 New Cholesterol Genes Identified

December 08, 2008
Could be targets for drug treatment, researchers note. An international research team that screened the genes of more than 40,000 people has identified 11 more regions that govern levels of blood fats such as LDL cholesterol and triglycerides.

"These locations point us to previously unsuspected players in the metabolism of cholesterol in humans," said Dr. Sekar Kathiresan, director of preventive cardiology at Massachusetts General Hospital, and lead author of a report in the Dec.

Holidays Don't Have to Make You Heavier

December 07, 2008
Maintaining weight, instead of dieting, is a good way to keep pounds off, experts say. The holiday season is always extra challenging for those watching their weight, but there are ways to participate in the fun without packing on the pounds.

Julie Redfern, manager of the Nutrition Consult Services at Brigham and Women's Hospital in Boston, recommends trying to simply maintain your weight rather than shedding pounds as a good strategy. In a news release issued by the hospital, she also offered these tips:

Before going to a holiday party, eat a light snack.

Portion Distortion

December 07, 2008
In the fight against obesity, Americans need to re-learn proper serving sizes for meals. All-you-can-eat buffets, super-sized meals and cavernous drinks may help keep your wallet full, but they're also helping to expand your waistline.

Nutrition experts say portion control is one of the biggest factors in successfully losing weight. But Americans aren't very good at recognizing reasonable portion sizes anymore.

Vitamin K Slows Insulin Resistance in Older Men

December 05, 2008
But effect for women not same, as study cites obesity as possible cause. Vitamin K slows the development of insulin resistance in older men, but not women, a new study found.

Insulin resistance, a precursor to diabetes, occurs when the body cannot use insulin properly. As a result, glucose builds up in the blood.

Intestinal 'Sleeve' Mimics Effects of Gastric Bypass

December 04, 2008
Tests in rats show treatment device could be used to treat obesity in humans. Lining the upper small intestine with an impermeable sleeve may be as effective as invasive gastric bypass surgery to help people lose weight and avoid diabetes, a new report says.

The procedure, tested on rats by the Massachusetts General Hospital Weight Center and Gastrointestinal Unit, led to reduced appetite, weight loss and a return to a normal glucose levels.

Depression Linked to Increase in Abdominal Fat

December 03, 2008
Dutch researchers made the connection after studying adults ages 70 to 79. There may be a link between depression and abdominal obesity in older people, according to researchers in Holland who studied almost 2,100 adults in their seventies.

The participants were screened for depression at the start of the study (four percent had depression) and their levels of abdominal and overall body fat were recorded and then checked again five years later.

Exercise Eases Obesity and Anger in Kids

December 03, 2008
After-school aerobics helped youngsters feel better mentally, physically, researchers say. Overweight kids may be able to work out their anger with exercise, a new report finds.

Antibiotics Largest Cause of Drug-Induced Liver Damage

December 01, 2008
Prescription meds, supplements can also trigger acute organ failure, study says. Antibiotics are the single largest class of drugs that cause idiosyncratic drug-induced liver injury (DILI), researchers say.

The condition accounts for about 13 percent of cases of acute liver failure in the United States and is the most common cause of death from acute liver failure.

School Soda Ban Has Limited Effect

November 27, 2008
Eliminating sugary beverages did not affect overall consumption, study finds. A new study suggests that cutting sodas and other sugar-sweetened drinks from school cafeteria menus will have little effect on teens' overall consumption of the beverages.

Because these drinks are believed to be a major contributor to increasing rates of childhood obesity in the United States, many schools across the nation are banning them or curbing their availability to students.

Fat-Sensing Hormones Might Fight Obesity

November 26, 2008
Study with rodents shows the molecules help regulate appetite. As you push your chair back from the Thanksgiving table this year, a molecule produced in the small intestine will be swarming through your bloodstream, ready to register on your brain the impact of the fat you've just consumed.

"Thanksgiving isn't usually a calorie-conscious holiday, but by swapping out a few ingredients with healthier alternatives, you can really help reduce calorie and fat intake while keeping great flavor," Dr.

Weight Boosts Older Women's Breast Cancer Risk

November 25, 2008
It's the added pounds, not impaired detection, that's to blame, study concludes. Being overweight boosts the risk of getting advanced breast cancer for older women, according to a new study that looked at more than 287,000 women and took into account their mammogram habits.

The weight itself is to blame for the added risk, the researchers concluded.

Substitutions Make Holiday Fare Healthier
