  1. MVPA: Moderate- to vigorous-intensity physical activity. T3: 18-months (Nov-Dec 2011). T4: 30-months (Nov-Dec 2012). Analyses adjusted for school SEP, average accelerometry wear time, baseline values of the outcome variables and intervention group. In the models where sedentary breaks were included as the outcome variable, analyses were also adjusted for average sedentary time
