Body Roundness Index is better predictor than BMI for clinical problems
A recent study found that the Body Roundness Index (BRI) is a better predictor of adverse clinical effects than Body Mass Index (BMI), our usual surrogate marker for obesity-related adverse outcomes (see obesity body roundness index JAMA2024 in dropbox, or doi:10.1001/jamanetworkopen.2024.15051) Details: --32,995 US adults >20yo selected from the National Health and Nutrition Examination Survey (NHANES) were evaluated for the relationship between Body Roundness Index (BRI) and all-cause mortality, with mortality data derived from the CDC website and linked to the NHANES database -- since 1999, NHANES conducted surveys every 2 years based on in-home interviews and study visits; 10 cycles from 1999-2018 were included. Nonpregnant individuals were selected to be representative of the noninstitutionalized civilian population -- BRI was calculated as: 364.2 − 365.5 × √ 1 − [waist circumference in cen...
