BMI denotes body mass index defined by body weight in kilograms divided by height in meters squared. NHANES denotes National Health and Nutrition Examination Survey. Prevalence is weighed using NHANES sampling weights to be representative of the U.S. adult population in 2011-2012. Age is adjusted by direct standardization to the year 2000 Census population using the age groups 20–30 years old, 40–59 years old, and 60 years and older. 95% confidence interval is in parenthesis.
