Associations between 24-Hour Movement Behaviours and Global Cognition in a Cross-Sectional Sample of American Children

Background: Childhood is a critical period for brain development, and the behaviours that comprise a typical 24-hour day contribute to cognitive performance in children. This study investigated the relationship between cognition and meeting the 24-hour movement behaviour guidelines of ≥60 minutes of physical activity, ≤2 hours of recreational screen time, and 9-11 hours of sleep per day in 9-10 year olds.
