Note. FUP1 or 2 = follow-up 1 or 2; MVPA = moderate to vigorous physical activity. P values for cross-sectional analyses and change between 2 time points result from independent t test and regression analyses; P values for the intention-to-treat analysis are from unadjusted growth models (which include all participants) testing for intervention effect and refer to the significance of the interaction term of group and time. P values for MVPA are based on log-transformed values.

^a1 = never or rarely; 2 = occasionally; 3 = often; 4 = very often.
