Marriage may have an effect on weight -- so can divorce, a study finds. Researchers examined weight loss and gain in men and women in the two years following a marital transition, getting married or getting divorced. They found that there was a difference for the sexes: Men were at higher risk for gaining weight after divorce, while women were at higher risk of packing on the pounds following marriage. These weight gains were more likely to happen after age 30 -- before then, weight gains between just marrieds and unmarrieds weren't that dissimilar.

> > The day's best photos Disappears gets Saturday off to a rousing start with thundering bass lines and trancy beats from “fill-in” drummer Steve Shelley, who is taking a break from Sonic Youth to help out the Chicago quartet. With its reverbing vocals and guitars, and rhythms riding down the Autobahn first paved by German art-rockers Neu, Disappears plays under a thick blanket of gray. “Check it out, we brought the clouds,” the band says, and then makes a sound big enough to sound like the voice of doom descending.

As little as one hour of low-intensity exercise a week could reduce the risk of colon polyps among people of various racial and ethnic groups, a study finds. The study, presented recently at the Digestive Disease Week meeting in Chicago, analyzed data on 982 patients who underwent colonoscopies. Polyps were found in 29.5% of the study subjects. Patients who hadn't exercised at least one hour a week had a polyp prevalence of 33.2%, while the prevalence rate among those who did exercise one hour or more was 25.3%.

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.

For people with coronary artery disease, including those with a "normal, healthy" body-mass index (or BMI), having even a little flubber around the middle is a bad omen, increasing the risk of death as much as smoking a pack of cigarettes a day or having very high cholesterol. But having a BMI in the "overweight" or "obese" category does not, by itself, imply a grim prognosis, says a new study . The new research, published Monday in the Journal of the American College of Cardiology , makes clear that when it comes to body composition, it is better to be pear-shaped--carrying fat deposits in the hips, buttocks and thighs--than to be shaped like an apple, carrying excess fat around the middle.

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.

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.

When the National School Lunch Program began in 1946, the idea was to get nutritious food into the stomachs of malnourished children from low-income families. Ironic, then, that these days the school lunch program is being scrutinized for its role in contributing to the growing problem of childhood obesity in America. The latest report was published online this week by the Archives of Pediatric and Adolescent Medicine. It concludes that girls who participate in the National School Lunch Program gain weight at a faster clip than other girls from low-income families who do not get the subsidized lunches (and sometimes breakfasts)

Survivors of breast cancer may want to watch their post-diagnosis weight -- a study finds that women who gain a large amount of weight may be at greater risk of cancer recurrence and death. The study, being presented at the American Assn. for Cancer Research's meeting this week in Orlando, Fla., followed breast-cancer survivors in three groups from the United States and one from China. Women who gained 10% or more than their pre-diagnosis weight were 14% more likely to have the disease return compared with women whose weight stayed fairly steady, within 5% of their pre-diagnosis weight.

The body-mass index is a common measure of obesity. It's the ratio of weight in kilograms to height in meters squared. Here's how to calculate yours: (Your weight in kilograms) = (0.4535) x (your weight in pounds) (Your height in meters) = (0.0254) x (your height in inches) (Your BMI) = (your weight in kilograms) / (your height in meters, squared) For adults 20 years old or older, the National Institutes of Health have established these four categories based on BMI levels: Below 18.5underweight 18.5 to 24.9healthy 25.0 to 29.9overweight 30.0 or higherobese ?
