A mother's love usually makes for healthy and happy children, but in some cases it may be contributing to childhood obesity, a new study suggests.
In the study, researchers presented 281 mothers with cartoon drawings of toddlers ranging in size from scrawny to plump, and asked them to select the drawing that most closely resembled their child.
Nearly 70% of the women misjudged their toddler's body size, but the rate was much higher among the mothers of overweight children. Ninety-four percent of those mothers identified their child's size as being in the normal range, the study found.
Previous studies in older children have produced similar results. The new research, published this week in the Archives of Pediatric and Adolescent Medicine, is the first to show widespread misperceptions of body size among the parents of toddlers.

Older people with heart disease who undergo non-emergency procedures to restore blood flow to their heart generally have better long-term survival odds with bypass surgery than with angioplasty, according to new research published online in the New England Journal of Medicine.
The study included about 190,000 men and women over age 65 who had bypass surgery or angioplasty - a far less invasive procedure - between 2004 and 2008. One year after the procedures, the survival rates for both groups hovered just under 94%. At the four-year mark, however, 84% of the bypass patients and 79% of the angioplasty patients were still alive.
The difference in survival rates was consistent across several key subgroups of patients, including men and women, high- and low-risk patients, and those with and without diabetes, the study found. FULL POST

Popcorn isn't just low in calories and high in fiber. Turns out the popular snack is chock full of antioxidants, too.
Per serving, plain popcorn contains nearly twice as many polyphenols as the average fruit, according to the preliminary results of a laboratory analysis presented today at the annual meeting of the American Chemical Society.
Polyphenols, a type of plant-based chemical found in foods ranging from vegetables to chocolate, help neutralize the harmful substances known as free radicals and are thought to protect against heart disease and other health problems.

Each year, nearly 20 million men, women and children in the United States fail to see a family physician or similar health care professional, but they do pay at least one visit to the dentist, according to a new study in the American Journal of Public Health.
For this segment of the population, dentists may be the only doctors in a position to spot the warning signs of chronic illnesses, such as diabetes, and provide referrals or advice to prevent serious complications, says Shiela M. Strauss, Ph.D., the lead author of the study and an associate professor at New York University's Colleges of Dentistry and Nursing.
Oral or dental abnormalities can signal a broad range of body-wide health problems, including HIV, sexually transmitted diseases, eating disorders, and substance abuse, in addition to diabetes. In a previous study, for instance, Strauss and her colleagues found that 93% of patients with gum disease (such as gingivitis) also met the criteria that should trigger blood-sugar screening under American Diabetes Association guidelines.

People with celiac disease are accustomed to being on the lookout for gluten in their food, but they should also be aware of the gluten lurking in their cosmetics and toiletries, researchers warned Monday at a national meeting of gastroenterologists in Washington, D.C.
Food labels almost always say whether a product contains gluten, a type of protein found in wheat, barley, and other grains. But the packaging of body lotions and other beauty products rarely provides that information, even though many such products contain substances derived from grain, says Pia Prakash, M.D., a resident in internal medicine at George Washington University.

Mental health problems such as depression account for nearly half of all disability among young people between the ages of 10 and 24, according to a new study from the World Health Organization (WHO).
Researchers looked at data from 191 countries and estimated the number of years of good health lost to disability resulting from disease and injury (known as disability-adjusted life years). Among adolescents and young adults, 45 percent of disability was related to depression, bipolar illness, schizophrenia, and other mental disorders, including alcohol abuse.
