Background: The present study examines the effects of the COVID-19 confinement on health-related behaviors (physical activity, sedentary behaviors) of young French children.
Methods: Parents of 348 French children under 6 years of age completed an online survey launched during the first days of the initial COVID-19-related confinement. They were asked to indicate whether their kids increased, decreased or maintained their physical activity level, time spent in sedentary behaviors, and sleep time.
