Sleep in high-functioning children with autism: longitudinal developmental change and associations with behavior...

Area of Science:

• Neurodevelopmental disorders
• Pediatric sleep medicine
• Autism spectrum disorder research

Background:

• Sleep disturbance is a prevalent issue in children with autism spectrum disorder (ASD).
• Longitudinal patterns and changes in sleep disturbance over time within ASD populations are not well understood.
• Understanding these changes is crucial for identifying effective interventions and support.

Purpose of the Study:

• To investigate the longitudinal changes in sleep disturbance in children with ASD compared to typically developing (TYP) children.
• To examine the relationship between changes in sleep disturbance and problem behaviors, including social ability and anxiety.
• To define the trajectory of sleep disturbance in ASD over a one-year period.

Main Methods:

• A cohort of 84 gender-matched children (aged 7-12 at baseline), including 46 with ASD and 38 TYP children, was studied.
• Parental reports using standardized scales were collected at baseline and after one year to assess sleep disturbance and associated behaviors.
• Statistical analyses were performed to compare groups and examine changes over time and correlations.

Main Results:

• Children with ASD exhibited significantly higher levels of sleep disturbance compared to TYP children at baseline.
• Sleep disturbance notably decreased over the one-year study period in the ASD group, whereas it remained stable in the TYP group.
• A reduction in sleep disturbance was associated with improvements in social abilities among children with ASD.
• Baseline sleep disturbance emerged as a significant predictor of later anxiety symptoms in the ASD cohort.

Conclusions:

• Sleep disturbance follows distinct longitudinal trajectories in children with autism spectrum disorder.
• Interventions aimed at reducing sleep disturbance in ASD may positively impact social functioning and anxiety levels.
• Further research is warranted to explore the mechanisms underlying these sleep changes and their long-term implications for individuals with ASD.
