Lifestyle interventions improve 24-hour movement behaviors in preschool children

Lifestyle interventions were associated with increases in moderate-to-vigorous physical activity (MD 5.77 min/day) and sleep duration (MD 0.18 h/day), and reductions in sedentary behavior (MD -7.62 min/day) and screen time (MD -0.33 h/day) in preschool children aged 2-6 years. However, heterogeneity was substantial and the certainty of evidence was low.
