  • Model 1: Adjusted for age, sex, district, educational level, smoking consumption, drinking status and physical activity level.

  • Model 2: Included variables in model 1 and further adjusted for body mass index, systolic blood pressure and diastolic blood pressure.

  • Model 3: Adjusted for factors in model 2 plus total cholesterol and low-density lipoprotein cholesterol.

  • Model 4: Model 3 plus fasting plasma glucose.

  • HDL-C, high-density lipoprotein cholesterol; TG, triglyceride.
