Note: Boldface indicates statistical significance (p<0.05).
National Longitudinal Study for Adolescent and Adult Health. Associations estimated from gender-stratified latent growth curve models. Adjusted for race/ethnicity, parental education, parental income at Wave I; and time-varying smoking, participant income, and participant education. All estimates except individual association model obtained from mediation model. CIs for indirect and total effects were not calculated due to the numerical integration used in the model.
Individual association model includes maltreatment class predicting BMI intercept and slope (without depression trajectory), adjusting for covariates listed in (a).
