  1. Values are presented as arithmetic means ± standard deviations. Means across weight status categories were compared by Scheffe’s tests, and P trend was assessed by linear contrast
  2. Information on fasting plasma glucose and insulin was missing for 1 participant, on HOMA2-IR for 3 participants and on TG, HDL-C and TG/HDL-C ratio for 91 participants
  3. CDC Centers for Disease Control and Prevention; DBP diastolic blood pressure; HDL-C high-density lipoprotein cholesterol; HOMA2-IR homeostatic model assessment 2 of insulin resistance; IOTF International Obesity Task Force; SBP systolic blood pressure; TG triglycerides; WC waist circumference; WHO World Health Organization
  4. 1, 2, 3,Values with different superscript numbers are statistically different (P < 0.05)
