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%.

About 18% of youths 12 to 19 are obese, as well as 20% of children 6 to 11 and 10% of those 2 to 5 years old. These Centers for Disease Control and Prevention figures date to 2008, but all indications are that those numbers are on the rise. How do you know whether your child is obese? You can't tell just by looking. One of the tools a doctor will use is a BMI growth chart that compares your child's body mass index, or BMI, calculated from his or her weight and height, with others of the same sex and age. Children who fall in the 85th to 95th BMI percentiles (meaning 85% to 95% of children have a lower BMI)

When a nearly 600-pound man who boldly promoted food at a restaurant called the Heart Attack Grill dies, one of the first reactions is likely to be ... , well, not one of surprise. But then comes the news that Blair River might have died of pneumonia. Hold on. Don't order up that 8,000-calorie burger just yet. Note that there is a potential link between obesity and pneumonia. "After accounting for factors such as lifestyle and education, moderately obese men -- those with a body mass index between 30 and 34.9 -- had a 40% greater risk of pneumonia compared with those of normal weight (BMI of less than 24.9)

People whose body mass index is considered normal and healthy may want to think twice about that designation if their waist-to-hip ratio is more suggestive of an apple than a pear, a new study from the Mayo Clinic finds. Normal-weight Americans with an accumulation of fat around the middle were more likely to die of heart disease, and of any other cause, during a 14-year study period than were people whose BMI categorized them as obese but who were more pear-shaped. In fact, they had the highest risk of cardiovascular death of all the categories, including people whose BMIs identified them as overweight or obese.

Don't add another half-hour to your Stairmaster time just yet. As health-conscious Southern Californians sweated out trying to calculate their "body mass index" Wednesday after a report was released the day before claiming to show that overweight Americans are now in the majority, the National Center for Health Statistics sheepishly backed away from the data that jolted so many Americans out of their recliners.

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.

When roasted at 475 degrees, coffee beans are sometimes described as rich and full-bodied. But for the full-bodied person who is not so rich, unroasted coffee beans - green as the day they were picked - may hold the key to cheap and effective weight loss, new research suggests. In a study presented Tuesday at the American Chemical Society's spring national meeting in San Diego, 16 overweight young adults took, by turns, a low dose of green coffee bean extract, a high dose of the supplement, and a placebo.

Americans have increased their life expectancy by cutting back on cigarettes, but the pounds they're packing on mean that, ultimately, they could lose ground. A New England Journal of Medicine study published Wednesday looked at previous national health surveys to forecast life expectancy and quality of life for a typical 18-year-old from 2005 through 2020. Declines in smoking over the last 15 years would give that 18-year-old an increased life expectancy of 0.31 years. However, growing body mass index rates would also mean that that teen would have a reduced life expectancy of 1.02 years, giving a net life expectancy reduction of 0.71 years.

Physical education class has long suffered from an image problem. Children often deem jumping jacks and chin-ups boring or goofy; parents wonder if the time would be better spent on reading skills. But a new study makes a strong case that physical education may be the single best strategy for curbing the nation's growing child obesity problem -- at least among girls. In the first study to evaluate the effect of P.E.

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 … . 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...
