Model A adjusted for age, sex, and ethnicity. ORs are estimated by logistic regression analysis and refer to one standard deviation change in the natural log of the variable. Each row is an individual model with adjustments as indicated.

*AROC P < 0.05 compared with Table's most predictive model. % BF, percent fat from BIA.
