  • Obesity During Pregnancy Associated With Increased Risk of Birth Defects:

    For women who are obese during pregnancy there is an associated increased risk of certain birth defects, such as spina bifida and neural tube defects, although the absolute increase in risk is likely to be small, according to an analysis of previous studies, reported in the February 11 issue of JAMA. (American Medical Association, 2/10/09)

  • Researchers Uncover ‘Obesity Gene’ Involved in Response to High-Fat Diet

    Scientists have determined that a specific gene plays a role in the weight-gain response to a high-fat diet. The finding in an animal study suggests that blocking this gene could one day be a therapeutic strategy to reduce diet-related obesity and associated disorders, such as diabetes and liver damage, in humans. (Ohio State University, 2/24/09)

  • Love Handles Put the Squeeze on Lungs

    A new study has found that a high waist circumference is strongly associated with decreased lung function—independent of smoking history, sex, body mass index (BMI) and other complicating factors.(American Journal of Respiratory and Critical Care Medicine, 3/6/09)

  • Infant Weight Gain Linked to Childhood Obesity

    An ongoing study of pregnant women and their babies has found that rapid weight gain during the first six months of life may place a child at risk for obesity by age 3. Researchers studied 559 children, measuring both weight and body length at birth, 6 months, and 3 years. They found that sudden gains […]

  • Big Belly and Obesity Linked to Increased Risk of Restless Legs Syndrome

    A new study shows both obesity and a large belly appear to increase the risk of developing restless legs syndrome (RLS), a common sleep disorder characterized by an irresistible urge to move your legs.

  • Obesity Rates Differ Among Racial/Ethnic Groups in Kids as Young as 4

    Obesity is twice as common in young American Indian/Native Alaskan children as it is in white and Asian children, according to new research offering the first nationally representative analysis of obesity prevalence among preschool-aged kids in five major racial/ethnic groups. (Ohio State University, 4/6/09)

  • Ignoring an Epidemic: Examining Weight Loss Tactics, Doctor’s Role in Helping African-Americans Lose Weight

    The conversation on weight management isn’t taking place between patient and physician. And when it does. many patients don’t like what they’re hearing.

And when they […]

  • New Data Analysis Shows Possible Link between Childhood Obesity and Allergies

    A new study indicates there may be yet another reason to reduce childhood obesity — it may help prevent allergies. The study published in the May issue of the Journal of Allergy and Clinical Immunology showed that obese children and adolescents are at increased risk of having some kind of allergy, especially to a food. (National […]

  • Obese Moms, Asthmatic Kids

    Babies born to obese mothers may have an increased risk of asthma, according to data from a new study to be presented on May 19 at the 105th International Conference of the American Thoracic Society in San Diego. (American Thoracic Society, 5/20/09)

  • “Eating for Two” Has Consequences for Mom and Baby

    There is more medical evidence that pregnant women should steer clear of advice to “eat for two.” Alison Stuebe, M.D., at the UNC Chapel Hill School of Medicine, found that women who consumed extra calories, as well as fried foods and dairy, had excessive gestational weight gain. The good news: there are concrete messages care […]

  • Exercise Keeps Dangerous Visceral Fat Away a Year After Weight Loss

    A study conducted by exercise physiologists in the University of Alabama at Birmingham (UAB) Department of Human Studies finds that as little as 80 minutes a week of aerobic or resistance training helps not only to prevent weight gain, but also to inhibit a regain of harmful visceral fat one year after weight loss. (University of […]

  • Diet-Exercise Combo Best for Obese Seniors

    For obese seniors, dieting and exercise together are more effective at improving physical performance and reducing frailty than either alone. Although weight loss alone and exercise alone improve physical function, neither is as effective as diet and exercise together, which improved physical performance in seniors by 21 percent. (Washington University in St. Louis, 3/30/11)

  • Too Much Weight May Delay Infants’ Ability to Crawl, Walk

    Those cute little rolls of fat some infants have may actually slow their ability to crawl and walk, according to a new study by the University of North Carolina at Chapel Hill.
