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