  1. Data are mean (SD).
  2. SD – standard deviation; SDS-BMI – standard deviation of body mass index; SDS-waist circumference – standard deviation of waist circumference; BIS – Bio-electrical impedance spectroscopy; HDL – high-density lipoprotein; LDL – low-density lipoprotein; HS-CRP - high sensitive C-reactive protein; HbA1C – hemoglobin type A1C; HOMA-IR – homeostasis model assessment for insulin resistance; EQ-5D – EQ-5D descriptive system; R – correlation.
  3. Median is 3.46.
  4. † P value = 0.05.
  5. * P value <0.05.
  6. ** P value < 0.01.
  7. 1 Three stages based on Tanner stages: ‘prepubertal’ equals G/M1&P1; ‘postpubertal’ equals G/M5&P5; ‘pubertal’ equals all other Tanner stages.
  8. NA Not applicable.
