Model 1: no covariates were adjusted. Model 2: age, gender, and BMI were adjusted. Model 3: age, gender, race, educational level, BMI,family income-to-poverty ratio, moderate activities, smoking status, alcohol use status, take prescription for cholesterol, prevalence of diabetes, prevalence of arthritis, ALT, AST, ALP, total calcium, globulin, female postmenopausal status, and serum phosphorus were adjusted
