  • * Restricted to subjects whose BMI in adulthood was ≥30 mg/dL and had at least 2 examinations during childhood (at ≤8 y and at 12–17 y).

  • The mean adult BMI level differed significantly across all 3 groups.

  • Adult risk factor levels have been adjusted for differences in race, sex, age, examination year, and adult BMI level in the 3 categories. Mean levels of triglycerides and insulin are based on log transformed values.
