  1. Abbreviations: WC, waist circumference; HC, hip circumference; WHR, waist-to-hip ratio; BMI, body mass index; TBF, total body fat.
  2. a) Multiple regression analyses using the log-transformed 25-hydroxyvitamin D3 as the dependent variable and the respective anthropometric and body composition parameters as the predictor variables. The results of the regression analyses are expressed in terms of B (the unstandardised coefficient), ß (standardised coefficient), and the adjusted coefficient of determination (R2) for the final model 3. Model 1: association adjusted for age (y). Model 2: model 1 with additional adjustments for physical activity level, sun exposure (min/d), vitamin D intake (μg/d), calcium intake (g/d), alcohol consumption (g/d), smoking (never-smokers vs. current or ex-smokers) and use of vitamin D supplements (no/yes). Model 3: model 2 controlled for intact parathyroid hormone (pmol/L).
  3. b) Adjusted coefficient of determination (R2) for the respective model 3 (including the respective anthropometric and body composition variable and all covariates) for women (WC = 0.243; HC = 0.238; WHR = 0.235; BMI = 0.252; and % TBF = 0.274) and for men (WC = 0.275; HC = 0.270; WHR = 0.276; BMI = 0.271; and % TBF = 0.270).
