LB: lower body; Tt.BMD: total bone mineral density; Ct.BMD: cortical bone mineral density; Ct.Th: cortical thickness; aBMD: areal bone mineral density. Stepwise regression model controlling for age, object length, and muscle area (for pQCT variables) and age, height, and subtotal lean (for DXA variables) as possible confounders.
