Note: results expressed as standard β coefficients. A/G FMR: android/gynoid fat mass ratio; WBLM: whole-body lean mass; WBFM: whole-body fat mass; WB BMD: whole-body bone mineral density; LS BMD: lumbar spine bone mineral density; FN BMD: femoral neck bone mineral density; TH BMD: total hip bone mineral density.
