Meeting 24-hour movement behavior guidelines in young children: Improved quantity estimation and self-regulation

Research Findings: The present study examined the associations among meeting 24-hour movement behavior recommendations set by the World Health Organization (2019) and young children's self-regulation and quantity estimation skills in a sample of 123 children (n = 65 female; 4.9 +/- 0.7 years) in mid-Michigan. Meeting screen time recommendations alone, meeting physical activity recommendations in combination with either sleep or screen time recommendations, meeting more recommendations overall, and being active more days weekly were associated with superior quantity estimation. Meeting more guidelines and accruing more moderate-to-vigorous physical activity daily related to better self-regulation. Improvements in self-regulation partially mediated the relation between physical activity and quantity estimation. Practice or Policy: Our findings identify benefits for adopting specific physical activity guidelines for children (e.g., physical activity, screen time, and sleep duration) and integrating these into early learning standards so both families and schools can support children's capacity to meet 24-hr movement guidelines and thus support cognitive health. An active lifestyle in early childhood may support young children's self-regulation and early educational outcomes, with physical activity promotion efforts during early childhood serving as a viable means to address growing expulsion rates in preschool-aged children.
