Notes: Model 1: unadjusted. Model 2: adjusted for age, gender, race/ethnicity, and season. Model 3: adjusted for model 2 + (shiftwork, vitamin D supplement intake, HDL cholesterol). Adj R²: adjusted R² values.

Abbreviations: 25(OH)D, 25-Hydroxyvitamin D; Abht, abdominal height; BMI, body mass index; FMI, fat mass index; HDL, high-density lipoprotein; PBF, percent body fat; WC, waist circumference; WCHtR, WC-to-height ratio.

^aStandardized β coefficient. The coefficient represents change in 25(OH)D for 1 SD increase in adiposity.
