Sleep patterns in children with and without autism spectrum disorders: developmental comparisons

Area of Science:

• Neurodevelopmental Disorders
• Pediatric Sleep Medicine
• Child Psychology

Background:

• Autism spectrum disorder (ASD) is a neurodevelopmental condition often associated with sleep disturbances.
• Sleep problems in children can significantly impact daily functioning and overall well-being.
• Understanding age-related sleep patterns in ASD is crucial for targeted interventions.

Purpose of the Study:

• To compare age-related sleep changes in children with ASD versus typically developing (TD) children.
• To investigate specific sleep domains affected in children with ASD.
• To determine if sleep problems in ASD diminish with age.

Main Methods:

• Mothers of 108 children with ASD and 108 TD children completed a comprehensive sleep questionnaire.
• The questionnaire assessed overall sleep quality and specific domains: bedtime resistance, sleep onset delay, sleep duration, sleep anxiety, night wakings, parasomnias, disordered breathing, and daytime sleepiness.
• Statistical analyses examined age-related differences and interactions between diagnostic group and age.

Main Results:

• Children with ASD exhibited significantly poorer sleep quantity and quality compared to TD children.
• Sleep problems were particularly evident in children with ASD aged 6-9 years.
• Unlike TD children, sleep difficulties in children with ASD were not likely to decrease with age, showing significant age-related interactions.

Conclusions:

• Sleep disturbances are a persistent issue for children with ASD, with limited improvement over time.
• It is essential to assess specific sleep domains rather than just overall sleep patterns in children with ASD.
• Combining children of wide age ranges can obscure important developmental differences in sleep within the ASD population.
