Notes: Crude model: we did not adjust other covariates. Minimally adjusted model: we adjusted age and BMI. Fully adjusted model: we adjusted Age; BMI; FBG, mmol/l; 25(OH)D, nmol/l; ALT, U/L; AST, U/L; Calcium intake, g/week; Outdoor time, h/day; Walking time, h/day; Smoking; Drinking; Chronic Kidney disease (CKD); Chronic obstructive pulmonary disease (COPD); Diabetes; Hyperthyroidism; Hyperlipemia and Chronic diarrhea.
