1003 SLEEP DISORDERED BREATHING AND SLEEP RELATED MOVEMENTS IN CHILDREN CLINICALLY REFERRED FOR EVALUATION AND TREATMENT OF INSOMNIA Article Swipe

Pediatric Insomnia may co-occur with primary sleep disorders including obstructive sleep apnea (OSA) and/or periodic limb movement disorder (PLMD). Limited research examining comorbidity of pediatric insomnia with other primary sleep disorders has focused on quantifying prevalence of insomnia symptoms in children referred for sleep disordered breathing evaluation and/or with polysomnography (PSG) confirmed OSA. Because PSG has limited utility for evaluation of primary insomnia there are few pediatric studies reporting PSG parameters for children with clinically diagnosed insomnia. The current study examined sleep and sleep disorders symptoms in children referred for insomnia evaluation who presented with insomnia symptoms in the absence of reported symptoms suggestive of other primary sleep disorders (e.g., snoring). Insomnia evaluation included clinical interview and completion of age-specific standardized sleep screening surveys (Child Sleep Habits Questionnaire, Sleep Disorders Inventory for Students, Adolescent Sleep Wake Scale, and Adolescent Sleep Hygiene Scale). Children 7.15 +/- 4.76 years old (N=499, 43.7% female, 81.4% Caucasian) were seen for insomnia evaluation and met ICSD criteria for insomnia. A subset of the insomnia patients (n=94) deemed at risk for OSA, restless legs syndrome (RLS), and/or PLMD were referred for medical sleep evaluation. Available PSG parameters were reported for insomnia patients undergoing medical sleep evaluation. Nearly 20% (n=94) of the insomnia sample were referred for medical sleep evaluation; 18% (n=17) of the subsample completed polysomnography within 4.06 ± 2.05 months of baseline insomnia evaluation. Five patients met pediatric PSG criteria for OSA (OI≥1) and one patient had a clinically elevated PLMI (≥5). Overall, less than 1% of the insomnia sample met pediatric PSG criteria for OSA and/or PLMD. Current findings suggest low prevalence of OSA and PLMD in clinically referred children identified before formal evaluation as having significant insomnia symptoms and minimal to no symptoms of other primary sleep disorders.
