  1. Hypertension is defined as normal (SBP < 120 and DBP < 80 mmHg), Elevated (SBP 120–129 and DBP < 80 mmHg); hypertension stage 1 (SBP 130–139 or DBP 80–89 mmHg); hypertension stage 2 (SBP ≥ 140 or DBP ≥ 90 mmHg)
  2. BMI defined as underweight (< 18.5), normal (18.5–24.9), overweight (25.0–29.9) and obese (≥ 30)
  3. Waist circumference is defined as normal, overweight and obese for men (< 94, 94–102 and ≥ 103 cm) and women (≤ 80, 80–88, and ≥ 89 cm), respectively
  4. Waist-to-hip ratio is defined as normal, overweight and obese for men (≤ 0.95, 0.96–1.0 and ≥ 1.1) and women (≤ 0.80, 0.81–0.85, and ≥ 0.86), respectively
  5. n, number; *p < 0.05 and **p < 0.05 significant by Univariate ANOVA (F-test) for gender difference in subgroup and group, respectively
