Note. N = 315 for boys, 764 for girls. All models are adjusted for cohort, race/ethnicity, and weight status from Time 1 to Time 2. R² = percent variance explained by separate and combined predictor models. Each of 12 single predictor models includes predictor, change in predictor, and covariates. Combined models include all personal, all socio-environmental, or all predictors as well as change in predictor and covariates. Statistically significant odds ratios (p < .05) are shown in bold type.
