Abstract

Aims: The purpose of the study was to increase the body of knowledge related to sleep in children with autism. The specific aims were to (i) identify the subgroup of children with autism, ages 3-17 years, referred for polysomnography and (ii) describe types and frequency of clinical encounters for sleep problems in a sample of children ages 3-17 with and without the diagnosis of autism.

Methods: The authors performed a secondary data analysis of the de-identified Nationwide Children's Hospital Sleep DataBank, a collection of encounters with children referred for polysomnography. The data were filtered for ages 3-17 years at the time of the participant's first sleep study, and further filtered for the presence of an autism diagnosis.

Results: In the sample, there were 2838 unique participants (M = 10.5 years) with a total of 172 167 encounters between 2017 and 2019. Of these, 198 (7%) were diagnosed with Autism Spectrum Disorder, Asperger's Syndrome, or Pervasive Developmental Disorder. Among all participants, the most common sleep problems were apnea, snoring, non-specified sleep disorders (including restless sleeper), circadian rhythm disorder (CRD), and insomnia. The subgroup of patients diagnosed with autism was noted to have higher frequency of several types of sleep problems, especially restless sleep, CRD and insomnia, compared to those without an autism diagnosis.

Conclusions: Findings elucidate the increased presence of sleep problems in paediatric patients with autism, and the need for purposeful sleep evaluation and research given the potential impact on daytime function for these individuals and their families.
