MGB study indicates dramatic increase in U.S. adults who meet new definition of obesity
""We already thought we had an obesity epidemic, but this is astounding,""
""With potentially 70% of the adult population now considered to have excess fat, we need to better understand what treatment approaches to prioritize.""
""We have always recognized the limitations of BMI as a single marker for obesity because it doesn't take into account body fat distribution,""
The Lancet Diabetes and Endocrinology Commission expanded the obesity definition to include body fat distribution measures in addition to BMI. Under the new criteria, obesity prevalence increased from 42.9% to about 68.6% among more than 300,000 U.S. adults. Obesity prevalence varies by sex, race, and age, reaching nearly 80% among adults over 70. The new criteria use waist circumference, waist-to-height ratio, and waist-to-hip ratio to distinguish fat from muscle mass. Obesity is defined as high BMI plus at least one elevated anthropometric measure, or normal BMI plus at least two elevated measures. Individuals with anthropometric-only obesity show higher risks of diabetes, cardiovascular disease, and mortality than people without obesity.
