Abstract Purpose The objective of the present study was to investigate the prevalence of insomnia and excessive sleepiness in relation to the presence and severity of obstructive sleep apnea (OSA). Methods The sample consisted of patients referred to a university hospital on suspicion of OSA. In total, 1115 patients with mean age of 48 years were studied. Insomnia (Bergen Insomnia Scale) and excessive sleepiness (Epworth Sleepiness Scale) were diagnosed using validated questionnaires. The insomnia scale permits diagnosing insomnia using both old and new (from 2014) criteria. OSA was diagnosed and B. Bjorvatn : S. Lehmann : S. Gulati : S. Pallesen : I. W.

categorized based on a standard respiratory polygraphic sleep study using a type 3 portable monitor. Results OSA was diagnosed in 59.4 % of the referred patients. The prevalence of excessive sleepiness was higher with greater severity of OSA: 40.5 % in the patients without OSA (apnea-hypopnea index (AHI)
