  1. Continuous data are expressed as mean ± standard deviation.
  2. Increased arterial stiffness = pulse wave velocity (PWV) ≥ 12m/s and, this was used as dependent variable in the logistic model.
  3. Analysis of PWV variable is adjusted for age, gender, mean blood pressure (MBP), ethnicity, body mass index (BMI), and smoking.
  4. * Model 1: adjusted for age, gender, and MBP.
  5. ** Model 2: adjusted for age, gender, MBP, ethnicity, BMI, smoking, and dyslipidemia.
  6. ¥Adjusted by model 1 plus hypertension or by model 2 plus hypertension.
  7. Hypertension = mean systolic blood pressure ≥ 140 mmHg and/or diastolic blood pressure ≥ 90 mmHg or use of anti-hypertension drugs.
  8. Diabetes = fasting glucose ≥ 126 mg/dL and/or use of hypoglycemic drugs.
