Overweight adults are significantly more likely to sustain injuries that require medical treatment than their normal-weight peers, according to a study in the May/June issue of the American Journal of Health Promotion (2007; 21 , 460). The risk is nearly twice as high for the extremely obese.
Researchers analyzed data from a survey of medical expenditures administered by the federal Agency for Healthcare Research and Quality. The 42,304 adults who participated noted all their medical conditions, injuries and healthcare costs from 1999 to 2002. As BMI increased, so did the risk of sustaining an injury requiring medical treatment. Overweight adults (BMI between 26 and 29) had a 15% higher risk of injury than normal-weight adults. Morbidly obese adults (BMI of 40 or over) had the greatest risk of injury—48% higher than normal-weight adults.
