Parents
In model 1, which included the total log-in duration, total number of sessions completed, and covariates, there was a positive effect of total log-in duration such that parents who spent more time logged in during the 8-week program had greater MVPA (In summary, parents who logged into the PA session had lower MVPA, but MVPA increased with greater log-in duration for the PA and sedentary behavior sessions. These associations remained even after accounting for engagement with other content sessions. In addition, logging in to the fast food session was associated with greater MVPA, but the log-in duration for this session was not significantly associated with MVPA. Although model 1 indicated that total log-in duration was positively associated with greater MVPA, this effect was no longer significant when engagement for the different content sessions was included in the model.
