Abbreviations: SM skeletal muscle mass, BMC bone mineral content, HDL high-density lipoprotein, HOMA-IR homeostasis model assessment of insulin resistance. Values are standardized ß-coefficients. Model 1 includes age. Model 2 includes Model 1 plus body composition parameters and waist/height ratio. Model 3 includes the Model 2 variables plus albumin and testosterone. Model 4 includes the Model 3 variables plus metabolic variables. ^a0.05 > P ≥ 0.01. ^b0.01 > P ≥ 0.001. ^cP < 0.001. “−” indicates not included in model. Adiponectin, HOMA-IR, HDL and triglycerides were log-transformed for analyses.
