Screening for Comorbidity of Sleep Disorders in Career Firefighters.

Background: The purpose of this study was to assess the prevalence and sequelae of insomnia, obstructive sleep apnea (OSA), and comorbid OSA and insomnia (COMISA).

Method: In the morning, after a shift end, Midwest career firefighters ( N = 89) in a midsized city completed an electronic battery of questionnaire to screen for OSA, daytime sleepiness, insomnia, presleep arousal, nightmares, mental and physical health symptoms, and a one-night sleep diary.

Results: Prevalence of firefighters exceeding screening thresholds: OSA: 54%; insomnia: 30%; COMISA: 17%; four or more nightmares per month: 15%.
