CI, confidence interval; HR, hazard ratio; N, number of cases./Model 1: Only WC and BMI were included as independent variables./Model 2: Adjusted for age, TC, HDL-C, LDL-C, FPG, TG, smoke and alcohol status, family history of hypertension, SBP and DBP./No multicollinearity was found among triglycerides, HDL-C, total cholesterol and LDL-C, because tolerance values were >0.5, VIF<10./*Significantly greater odds, P < 0.05./**Significantly greater odds, P < 0.01.
