Model 1 was not adjusted. Model 2 was adjusted for age and gender. Model 3 was adjusted for all covariables in model 2 plus race education, moderate recreational activities, diabetes, uric acid, total calcium, serum phosphorus, waist circumference, low-density lipoprotein cholesterol, smoke status, 25-hydroxyvitamin D(25OHD). Model 4 was adjusted for all covariables in model 3 plus antihyperlipidemic agents
