0967 Clinical Characteristics of Children With Sleep Problems and Comorbid Psychiatric Disorders

Abstract

Abstract Introduction Anxiety and Attention Deficit Hyperactive Disorder (ADHD) are common psychiatric comorbidities in children with sleep disorders. It is known that comorbid psychiatric disorders increase the risk of sleep problems. However, no study has compared the clinical characteristics of children presenting with sleep problems and various common psychiatric disorders. Methods Retrospective chart review of all children presenting to the sleep clinic for sleep problems between March 2016 to June 2017 was performed. Demographics, sleep intake patient questionnaires, polysomnograms and ICD-9/10 codes for comorbidities and sleep diagnoses were collected. In children with diagnoses of anxiety (ICD-9 300/ICD-10 F41) and ADHD (ICD-9 314/ICD-10 F90), demographics, presenting symptoms, Epworth sleepiness scores and prevalence of sleep comorbidities were compared. T-test (continuous) and Chi Square (categorical) were used. Unadjusted odds ratio was calculated for presenting symptoms and sleep comorbidities. P value of <0.05 was considered significant. Results 250 (F=145, 58%) children were evaluated. 71.2% children were diagnosed with anxiety and 28.8% diagnosed with ADHD. Mean age at presentation was 8.53 ± 4.2 years. Age, gender and race of children presenting with sleep problems and comorbid anxiety/ADHD were statistically similar. Children with anxiety spent less time in stage N3 sleep (25.2% ± 9.1 versus 28.6% ± 9.2) and had lower arousal indices (7.19 ± 3.8 versus 8.86 ± 5.5) compared to children with ADHD. Children with anxiety were more likely to present with chief complaint of “feeling tired or sleepy during the day” (OR:2.38, 1.32-4.37) and were more likely to have a diagnosis of hypersomnia (OR: 11.67, 3.19-42.75) versus children with ADHD. Conclusion Children with psychiatric comorbidities have distinct polysomnographic characteristics. Children with anxiety are more likely to present with daytime sleepiness and have a significantly higher prevalence of hypersomnia compared to children with ADHD. Support None
