Note. MVPA = moderate-to-vigorous physical activity (minutes); EMA = ecological momentary assessment; z-BMI = body mass index z-score; between=grand-mean centered variable; within = person-mean centered variable. Gender was coded such that boys were the reference category. Bolded values indicate significant effects at p < .05.
