  1. BMI – body mass index, SD – standard deviation, WC – waist circumference, SBP – systolic blood pressure, DBP – diastolic blood pressure.
  2. Values are presented as mean ± SD or median (25th–75th percentiles).
  3. aSignificantly different (p < 0.05) from normal weight participants.
  4. bSignificantly different (p < 0.05) from overweight participants.
  5. *Differences between three groups.
