Base model includes covariates (adolescent weight status, race/ethnicity, socioeconomic status, and cohort) and baseline level of the dependent variable. Maternal report model is base model with the addition of mother report variables (see text for description of models). Adolescent report model is base model with the addition of adolescent report variables. Full model is base model with the addition of all maternal and adolescent report variables.
aMaternal report and adolescent report blocks are mutually adjusted.
