BMI, body mass index; SBP, systolic blood pressure; DBP, diastolic blood pressure; FBG, fasting blood glucose; TC, total cholesterol; HDL-C, high-density lipoprotein cholesterol; LDL-C, low-density lipoprotein cholesterol; TG, triglycerides; HbA1c, glycosylated hemoglobin. The following variables were included in the multiple stepwise regression analysis: age, sex, BMI, SBP, DBP, FBG, TC, HDL-C, LDL-C, TG, and HbA1c.
