Being obese might up the chance of developing Type 2 diabetes, but the true risk factors may lie in how much overweight someone is and how long they've been that way. Much like figuring how numbers of cigarettes smoked and years of smoking relate to lung cancer risk, researchers set out to see how degree and length of obesity factored into the risk of getting Type 2 diabetes. They looked at data on 8,157 teens and young adults who were 14 to 21 years old at the start of a national study.

Weight may be a risk factor for a higher risk of death soon after major surgery, but it may not be obesity that's the problem. A study finds that people with a normal body mass index or who are underweight may be more likely to die after an operation. The study, released online Monday in the journal Archives of Surgery , examined data on 189,533 surgeries of people whose likelihood of death was known. Among those patients, 3,245 (1.7%) died in the month following surgery. Researchers divided the patients into five groups based on their body mass index for comparison.

Sometime later this year, the Centers for Disease Control and Prevention will release its latest accounting of the nation's weight problem, as measured by the body mass index, or BMI. This much we know already: It won't be a pretty picture. The last census reckoned that a third of American adults were overweight, meaning their BMIs (calculated by dividing a person's weight by his height, squared) lay between 25 and 30. About another third weighed in with BMIs over 30 -- the demarcation line that brands them as obese.

It's no surprise that someone who has never smoked, who eats a Mediterranean diet and keeps a normal weight and who exercises regularly is healthy. How healthy? Chances of death from all causes is reduced by 80% over eight years. Pretty healthy. Those four healthy behaviors also protected against heart disease and the buildup of calcium deposits in the arteries, the researchers said. Those are the results of a multiyear study of more than 6,000 people led by Johns Hopkins University researchers and published online Monday in the American Journal of Epidemiology.

Packing on even a few extra pounds in midlife can increase the risk of developing dementia, such as Alzheimer's disease, by 70% or more, Swedish researchers reported Monday. Earlier studies had shown an increased risk from being obese, but the new research reported in the journal Neurology is the first to show that simply being overweight is enough to increase the risk. "Our results contribute to the growing evidence that controlling body weight or losing weight in middle age could reduce your risk of dementia," co-author Dr. Weili Xu of the Karolinska Institutet in Stockholm said in a statement.

Heads up, those of you looking for the American Dietetic Assn. The organization, made up of food and nutrition professionals, has a new name: The Academy of Nutrition and Dietetics. The name change officially happened on Jan. 1, and the decision wasn't made lightly. In a news release academy President Sylvia Escott-Stump explained the thoughts behind changing the original name, which has been in place since the group was founded in 1917. "Protecting the public's health is the highest priority of the Academy and our members, and our new name complements our focus: the nutritional well-being of the American public.

The body mass index (BMI) isn't a perfect measure for obesity. Convenience and routine are on its side -- so health experts aren't likely to stop using it any time soon -- but its limitations have got some doctors thinking ÃÂÃÂ
. In a study published online Monday in the journal Pediatrics, researchers at the University of Michigan's Mott Children's Hospital found measurements of neck circumference to be a reliable technique...

The death of rapper Heavy D on Tuesday still has fans in shock as they wonder what felled the 44-year-old star. Though the cause of death may not be known for weeks, L.A. Now reports that an L.A. County coroner's office spokesman said a doctor had prescribed the rapper a drug due to a cough. Heavy D was also having breathing problems at his home before collapsing, and there is speculation that the rapper was experiencing flu-like symptoms or pneumonia. Some studies have shown a link between obesity and a higher risk of pneumonia.

To combat a growing problem with anorexia and bulimia, a new law in Israel bans fashion models who are considered unhealthily thin and requires the labeling of photos that are digitally altered to make the models look thinner. Unhealthily thin is defined as a body-mass index lower than 18.5. An example being tossed around is that a woman 5 feet 8 inches tall who weighs 120 pounds would be considered, well, not quite kosher for the cameras. That's a long way from zaftig, but certainly an improvement over the bony waifs that have too long been held up as icons of beauty.

Hey, what is your BMI? If that's a number you'd rather not share -- if, in fact, you can't help thinking there must be something wrong with the BMI calculator -- I feel your pain. And although I can't fix the calculator, I can tell you there's a growing debate over how good the body-mass index is as a predictor of an individual patient's health prospects. You can read about that whole debate: " BMI may not be telling the whole truth . " There's an inside joke often told at conferences convened to discuss the nation's epidemic of obesity: If the 72 million American adults with a body-mass index above 30 -- the demarcation line for obesity -- want to improve their health and avert a plague of weight-related diseases, they have two options: They can lose weight.
