  1. WC: waist circumference; HDL: high-density lipoprotein; LDL: low-density lipoprotein; SBP: systolic blood pressure; DBP: diastolic blood pressure;
  2. BMI: body mass index.
  3. † At significant level α = 0.05, p-value < 0.05 was used for ANOVA for differences in means and chi-square test for proportions among four different ethnic groups; p-value < 0.05** was used for two-sample t-test were used for comparing means and proportions between urban and rural Taiwanese.
  4. ‡ LDL is calculated from measured values of total cholesterol, triglycerides, and HDL according to the Friedewald calculation for US NHANES 2001-2002: [LDL] = [total cholesterol] - [HDL] - [triglycerides/5] where all values are expressed in mg/dL. The calculation is valid for triglycerides less than or equal to 400 mg/dL.
  5. ¥ Current smokers were considered to subjects who have a life-time smoking experience of ≥ 100 cigarettes and currently smoke.
