  1. Marginal means estimated from fully adjusted LMM (n = 537) which included group*time*sex interaction and lower order terms, child age, mother’s education, mother’s work status, having a yard big enough for running, dwelling type, length of follow-up, accelerometer data collection season, accelerometer data collected during COVID-19, and accelerometer wear time. Group*time interaction derived separately for boys and girls from the fully interacted model. Energetic play is the sum of walking, running, and moderate-to-vigorous activities and games. Total physical activity is the sum of light activities and games and energetic play
