Insights
Children with Autism Spectrum Problems (ASP) experience chronic insomnia at ten times the rate of their peers. These sleep issues are more persistent and develop more frequently over time in children with ASP.
Area of Science:
- Pediatric Sleep Medicine
- Neurodevelopmental Disorders
- Child Psychology
Background:
- Sleep problems are common in children.
- Autism Spectrum Disorders (ASD) are associated with various challenges, including sleep disturbances.
- Longitudinal data on sleep problems in children with Autism Spectrum Problems (ASP) is crucial for understanding chronicity and impact.
Purpose of the Study:
- To investigate the prevalence and chronicity of sleep problems in children with Autism Spectrum Problems (ASP).
- To assess the incidence and remission rates of sleep problems in children with ASP over time.
- To identify predictors of sleep problems in this population.
Main Methods:
- Longitudinal population-based study assessing children at ages 7-9 and 11-13.
- Autism Spectrum Screening Questionnaire (ASSQ) used to identify children with ASP.
- Sleep problems, including insomnia, were assessed, along with emotional and behavioral factors.
Main Results:
- Children with ASP had a >10x higher prevalence of chronic insomnia compared to controls.
- Incidence of new sleep problems was 37.5% in children with ASP vs. 8.6% in controls.
- Sleep problems in ASP were more persistent, with a remission rate of 8.3% vs. 52.4% in controls. ASP predicted sleep problems (OR=12.44), with a significant independent effect on insomnia (OR=3.25) after accounting for behavioral issues.
Conclusions:
- Children with Autism Spectrum Problems exhibit a significantly higher prevalence and chronicity of sleep problems, particularly insomnia.
- Sleep problems represent a persistent challenge for children with ASP, requiring targeted interventions.
- Increased clinical awareness and screening for sleep disturbances in children with ASP are warranted.
Abstract:
This study examined the prevalence and chronicity of sleep problems in children who manifest problems believed to be typical of Autism Spectrum Disorders (ASD). Using data from a longitudinal total population study, symptoms of ASD, insomnia and potential explanatory factors were assessed at ages 7-9 and 11-13. Children were included in a group defined as having Autism Spectrum Problems (ASP) if they scored above a strict threshold on the Autism Spectrum Screening Questionnaire (ASSQ). Twenty-eight (0.8%) of 3700 children fulfilled the selected criteria for ASP at both waves, and the prevalence of chronic insomnia was more than ten times higher in these children compared to the controls. Children with ASP developed more sleep problems over time, with an incidence rate at wave 2 of 37.5% compared to 8.6% in the controls. The sleep problems were more persistent over time, with a remission rate of 8.3% compared to 52.4% in the controls. ASP was a strong predictor of sleep problems at wave 2 (OR = 12.44), and while emotional and behavioural problems explained a large proportion of this association, the effect of ASP on insomnia remained significant in the fully adjusted model (OR = 3.25). These findings call for increased awareness of sleep problems in children with ASP.

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.
