Lagged models1of FM gain by baseline MVPA category or time engaged in MVPA
ΔFM (kg) N = 196 (Boys = 84, Girls = 112)
β 95%CI
Model 1. Baseline MVPA category (medium/low MVPA as reference)
Girls 2 −0.92 −1.34, -0.49*
Boys −0.05 −0.86, 0.75
Model 2. Time engaged in baseline MVPA (10 min/d)
Girls 3 −0.12 −0.21, -0.04*
Boys 0.03 −0.01, 0.01

Abbreviations: MVPA = moderate-vigorous physical activity, ΔFM = fat mass gain, β = regression coefficient, CI = confidence interval.

1 Adjusted by initial fat mass, energy intake and height, age, gender, socioeconomic status and changes in energy intake and height. Grouping variable: School affiliation during the first survey. R2 for model = 0.19.

2 P value of baseline MVPA category x gender interaction: 0.046.

3 P value of the time engaged in baseline MVPA x gender interaction: 0.09.

*P value < 0.05
