Insights
Higher physical activity in preschoolers is linked to better executive function and fewer sleep problems. Sleep issues partially explain how exercise benefits cognitive skills in young children.
Area of Science:
- Child Development
- Behavioral Science
- Sports Medicine
Background:
- Executive function is crucial for preschooler development.
- Physical activity is recognized for its cognitive benefits.
- The role of sleep problems as a mediator is under-explored.
Purpose of the Study:
- To investigate the relationship between physical activity and executive function in preschoolers.
- To examine the mediating effect of sleep problems in this association.
Main Methods:
- 159 preschoolers participated.
- Objective measurement of physical activity (ActiGraph GT3X-BT).
- Validated questionnaires for sleep problems and executive function.
- Correlation and mediation analyses were performed.
Main Results:
- All physical activity measures (LPA, MVPA, TPA) negatively correlated with executive function.
- Physical activity levels were negatively correlated with sleep problems.
- Sleep problems positively correlated with executive function.
- Sleep problems mediated 24.65-28.20% of the physical activity-executive function link.
Conclusions:
- Increased physical activity is associated with enhanced executive function and better sleep in preschoolers.
- Sleep problems partially mediate the positive impact of physical activity on executive function.
- Interventions promoting physical activity can improve sleep and foster executive function development.
Objective:
This study aimed to examine the relationship between physical activity and executive function in preschool children, with a particular focus on the mediating role of sleep problem.
Methods:
A total of 159 preschool children participated in this study. Physical activity levels were objectively measured using the ActiGraph GT3X-BT. Sleep problems and executive function were assessed using the Chinese versions of the Children's Sleep Habits Questionnaire and the Behavior Rating Inventory of Executive Function-Preschool Version. Statistical analyses including correlation and mediation analyses were conducted using SPSS 29.0 and Mplus 8.0.
Results:
(1) Light physical activity (LPA) (r = -0.53, p < 0.01), moderate-to-vigorous physical activity (MVPA) (r = -0.61, p < 0.01), and total physical activity (TPA) (r = -0.64, p < 0.01) showed significantly negatively correlated with executive function scores. (2) LPA (r = -0.27, p < 0.01), MVPA (r = -0.29, p < 0.01), and TPA (r = -0.31, p < 0.01) were significantly negatively correlated with sleep problems. (3) Sleep problems were significantly positively correlated with executive function scores (r = 0.47, p < 0.01). (4) Sleep problems mediated 24.65-28.20% of the effects of LPA, MVPA, and TPA on executive function.
Conclusion:
Higher levels of LPA, MVPA, and TPA were significantly associated with better executive function and fewer sleep problems in preschool children. Sleep problems play a partial mediating role in the relationship between physical activity and executive function. These findings suggest that preschool educators and parents should implement appropriate physical activity interventions to improve sleep health, ultimately fostering optimal executive function development in young children.
