*The analysis was adjusted for age, sex (not for adjusted in stratified analysis), season of blood collection, geographical location, smoking, drinking, physical activity, dietary vitamin D intake, body mass index (BMI), fat mass percentage (FMP), and muscle mass index (MMI).
†The diagnostic criteria are as follows: Abdominal obesity was defined as waist to height ratio ≥0.515; Hypertension was classified by the 95th sex, age and height-specific blood pressure cut-points of Chinese standard16; Abnormal blood lipids levels were classified by the age and sex-specific lipoprotein cut-points of Chinese children17; Hyperglycemia was defined as fasting blood glucose ≥5.6 mmol/L18; Insulin Rresistance was defined by the World Health OrganizationWHO as values in the highest quartile of the homeostasis model assessment of insulin resistance (HOMA-IR).19
‡Vitamin D status was classified by the Institute of Medicine (IOM) recommendation: deficiency, <30 nmol/L; inadequacy, 30 to <50 nmol/L; adequacy, ≥50 nmol/L.20
§Significantly different from the referent category, vitamin D adequacy group.
HDL-C, high-density lipoprotein-cholesterol; LDL-C, low-density lipoprotein-cholesterol; TC, total cholesterol; TG, triglyceride.
