Role of physical activity and sleep duration in growth and body composition of preschool-aged children

摘要

ObjectiveThe impact of physical activity patterns and sleep duration on growth and body composition of preschool-aged children remains unresolved. Aims were 1) to delineate cross-sectional associations between physical activity components, sleep, total energy expenditure (TEE) and body size and composition; and 2) to determine whether physical activity components, sleep and TEE predict 1-y changes in body size and composition in healthy preschool-aged children.
