Insights
Higher physical activity correlates with better sleep in children. However, this link is less clear for autistic children, particularly those with severe autism or females in younger age groups.
Area of Science:
- Pediatric Health
- Neurodevelopmental Disorders
- Sleep Science
Background:
- Establishing the link between physical activity and sleep duration in children is crucial.
- Understanding this relationship in autistic children is an under-researched area.
- Existing research suggests physical activity benefits sleep, but specific populations require further investigation.
Purpose of the Study:
- To investigate the association between physical activity levels and sufficient sleep duration in children aged 6-17.
- To examine how this association differs in autistic children compared to neurotypical children.
- To identify specific subgroups of autistic children where the physical activity-sleep association may be weaker or absent.
Main Methods:
- Utilized existing data from the 2018 National Survey of Children's Health.
- Included caregivers of children aged 6-17, with a focus on autistic children.
- Assessed physical activity (days active) and sleep duration, determining 'sufficient sleep' based on age-recommended hours.
Main Results:
- Higher physical activity levels were associated with sufficient sleep duration in the general child population.
- This association was weaker in autistic children.
- The association was not observed in autistic children with severe autism spectrum disorder, female autistic children, and autistic children aged 6-12.
Conclusions:
- Physical activity is a potential strategy for improving sleep duration in children.
- Personalized sleep interventions may be necessary for specific subgroups of autistic children.
- Further research is needed to understand and address sleep challenges in autistic populations.
Lay Abstract:
Higher levels of physical activity may be associated with improved sleep in children, but this relationship is still being determined, especially in autistic children. In this study, we used existing data from the 2018 National Survey of Children's Health. Caregivers of children 6-17 years old, including caregivers of autistic children, completed a questionnaire that included questions about physical activity (days active in the past week) and sleep duration. We then determined if children were obtaining the recommended hours of sleep for their age (i.e. sufficient sleep). We found that higher physical activity levels were associated with sufficient sleep duration, but this finding was weaker in autistic children. In particular, this association was not observed in autistic children with more severe autism spectrum disorder, female autistic children, and autistic children 6-12 years old. In conclusion, physical activity is a promising approach to help children obtain sufficient sleep duration. However, more personalized approaches to improving sleep may be needed for certain groups of autistic children.

Autism Spectrum Disorder
These core symptoms manifest differently among individuals, ranging from mild to severe. The disorder's complexity extends beyond its clinical presentation, encompassing a diverse range of biological, cognitive, and sociocultural influences.
