À propos de cet audio
In this episode, researchers Arch G. Mainous III, PhD, and Frank A. Orlando, MD, discuss their recently published study, “Body Mass Index vs Body Fat Percentage as a Predictor of Mortality in Adults Aged 20-49 Years." The study found that body fat percentage is a stronger predictor of 15-year mortality risk among U.S. adults than body mass index (BMI). Although BMI is widely used in clinics as the standard measure of body composition, it can potentially misclassify muscular individuals as overweight and miss cases of "normal-weight obesity," masking serious metabolic and heart disease risks. The study findings support reexamining how body composition is measured in clinical settings.
