  2. 1Each logistic regression model adjusted for age, gender, income, and urban-rural residence; among girls, further controlled for menarche status.
  3. 2Normal weight (5th percentile ≤ BMI < 85th percentile) group was the reference group in each model.
  4. 3Systolic blood pressure/diastolic blood pressure ≥ 90th percentiles of 2007 Korean CDC growth chart.
  5. 4Fasting blood glucose ≥ 100 mg/dL.
  6. 5Triglyceride > 150 mg/dL or Total cholesterol > 200 mg/dL or LDL-cholesterol: > 130 mg/dL or HDL-cholesterol: < 35 mg/dL.
  7. 6Among elevated waist circumference, elevated triglycerides, reduced HDL cholesterol, elevated blood pressure, elevated fasting plasma glucose based on the 2007 pediatric IDF definition.
  8. 7By BMI percentile of 2007 Korea growth chart, overweight (85th percentile ≤ BMI < 95th percentile); obesity (BMI ≥ 95th percentile).
