  2. 1Estimates shown as mean and standard error or %.
  3. 2Defined using 2007 Korea growth chart, Normal weight (5th percentile ≤ BMI < 85th percentile); overweight (85th percentile ≤ BMI < 95th percentile); obesity (BMI ≥ 95th percentile).
  4. 3P-trend <0.05 across weight status.
  5. 4Letters with different superscripts by weight status are significantly different at P<0.05 by Tukey’s multiple range test.
  6. 5P < 0.05 for between group comparisons.
  7. 6P < 0.05 for between group comparisons using χ2 tests.
  8. 7Atherogenic index = log (triglyceride/HDL-cholesterol).
  9. 8Definitions of metabolic co-morbidities are provided in Methods.
  10. 9Among elevated waist circumference, elevated triglycerides, reduced HDL cholesterol, elevated blood pressure, elevated fasting plasma glucose based on the 2007 pediatric IDF definition.
