Data are expressed as number (per cent) for categorical variables, as mean (SD) for continuous variables in case of normal distributions and medians (IQRs) otherwise.
The educational level was divided into low (primary school), medium-low (junior high school), medium-high (high school) and high (college or university or higher). The medical insurance level was divided into low (reimbursement rate<30%), medium (reimbursement rate 30–79%) and high (reimbursement rate ≥80%). Obesity was defined as a BMI ≥28 kg/m2. Central obesity was defined as WC ≥90 cm in men and ≥80 cm in women. High triglycerides was defined as triglyceride level ≥1.7 mmol/L.
BMI, body mass index; DBP, diastolic blood pressure; HDL-C, high-density lipoprotein cholesterol; LDL-C, low-density lipoprotein cholesterol; SBP, systolic blood pressure; WC, waist circumference.
