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.

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

If obesity rates continue to climb in the U.S. as they've done in the past, about half of all men and women could be obese in 20 years, adding an extra 65 million obese adults to the country's population. The figures are from a study released Thursday in the journal the Lancet (part of a four-part obesity series) that used past trends to predict what the future might look like in the U.S. and the U.K. if people keep gaining weight at that rate. It's not a pretty picture--along with expanding waistlines may come higher disease rates and, in turn, greater healthcare costs.

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.

Pregnant women might now have one more good reason to watch their diet and exercise: A new study links autism and developmental delays in young children to metabolic conditions, like obesity and diabetes, in their mothers. The findings, published in Monday's edition of the journal Pediatrics, found that women who had diabetes or hypertension or were obese were 1.61 times as likely as healthy women to have children with autism spectrum disorders. They also were 2.35 times as likely to have children with developmental delays.

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.
