  1. Continuous data are expressed as mean ± standard deviation.
  2. HDL-C: high density lipoprotein; LDL-C: low density lipoprotein.
  3. Biochemical data and blood pressures were adjusted for age, gender, and ethnicity.
  4. Analysis of PWV variable is adjusted for age, gender, mean blood pressure (MBP), ethnicity, body mass index, and smoking.
  5. Ethnicity is categorized as Amerindian, White, Mulatto (Brown or “pardo” in Portuguese, person with admixture between White and Black) and Black.
  6. Hypertension = mean systolic blood pressure ≥ 140 mmHg and/or diastolic blood pressure ≥ 90 mmHg or use of anti-hypertension drugs.
  7. Increased arterial stiffness frequency = pulse wave velocity (PWV) ≥ 12m/s.
  8. Diabetes = fasting glucose ≥ 126 mg/dL and/or use of hypoglycemic drugs.
  9. Dyslipidemia = total cholesterol ≥ 240 mg/dL, LDL-C ≥ 160 mg/dL, and/or use of hypolipidemic drugs.
  10. Individuals who had ever smoked more than five cigarettes per day for the last year were classified as smokers.
