Overweight/obese (OWOB) defined as ≥85%ile of age and sex according to the CDC 2000 growth reference for children 2–19 years. Metabolic risk (MetRisk) defined as being in the 4th quartile of an externally standardized metabolic syndrome risk z-score comprised of waist circumference, systolic blood pressure, reversed HDL, triglycerides, and HOMA-IR.
