Body Mass Index (BMI)
Obesity is a very prevalent problem in the US that impacts on health and mortality and is associated with billions of dollars in health care costs. The BMI, a measure of weight adjusted for height, is used widely throughout the world to identify obese individuals as well as the relationship between body mass and mortality. Obese BMI is generally considered a risk factor for mortality and this has been documented in studies of the general population as well as NFL players.
