Summary of the analytic model for objective 2 using weight concerns as an example

Note; With the exception of baseline weight concerns and breast development (assessed at age 9), all covariates were time-varying and assessed concurrently with encouragement of PA for weight loss. Baseline weight concerns was included in the model as a time invariant covariate to control for pre-existing levels of concern about weight. Similar models predicting BMI and MVPA were run with the exception that the model predicting BMI also included caloric intake as a time-varying covariate and the model for MVPA predicted MVPA at ages 13 and 15 only with baseline PA measured at age 11.
