Model 1: not adjusted.

Model 2: model 1 adjusted for age (continuous, years), gender (male and female), education (illiterate, primary or above) and marital status (married/cohabitation, single/divorced).

Model 3: model 2 adjusted for waist circumference (continuous, cm), body mass index (continuous, kg/m²), diastolic blood pressure (continuous, mm Hg), systolic blood pressure (continuous, mm Hg), C reactive protein (mg/L), plasma glucose (mg/dL), cigarette smoking (never smoke, used to smoke or still have) and alcohol drinking (never drink, used to drinking or still have).

BMI, body mass index; CHARLS, China Health and Retirement Longitudinal Study; HDL-C, high density lipoprotein cholesterol; LDL-C, low density lipoprotein cholesterol; TC, total cholesterol; TG, triglyceride.
