a High externalizing behavior defined as Child Behavior Checklist T score ≥ 65 at 24 months.
b Obesity defined as BMI-for-age at or above the 95th percentile of the sex-specific CDC BMI-for-age growth charts.
c Odds ratio (95% Confidence Interval) from logistic regression models, predicting odds of obesity at 24 months with high externalizing behavior (≥ 65) at 24 months relative to lower levels of externalizing behavior (< 65).
d Restricted to children who are not missing information on behavior problems at 24 months and who had 1 or more BMI measurements between 24 months and 6th grade (n = 1189); 199 of these children were missing BMI at 24 months.
e Maternal education at child's birth.
f Unable to estimate within this strata due to data sparseness.
g Seventeen with missing information excluded.
h Maternal depression defined as CES-D score > 16; Seventy-six with missing information excluded.
