Randomly selected participants ( N = 1,502; 50.7% men, 49.3% women), ages 40 to 70 yr. ( M = 53.6, SD = 8.5) were interviewed over the telephone. Insomnia and excessive sleepiness (hypersomnia) were assessed with the Bergen Insomnia Scale and the Epworth Sleepiness Scale, respectively. OSA symptoms were identified by self- or spouse reports on snoring, breathing cessa- tions during sleep, and being tired or sleepy. The prevalence of OSA was 6.2%. Among these participants with OSA, 57.6% reported insomnia and 30.1% reported excessive sleepiness. Furthermore, OSA symptoms were associated with self- reported obesity, hypertension, diabetes, and depression, but only in participants with comorbid insomnia or excessive sleepiness. Obstructive sleep apnea (OSA) is a common sleep disorder, charac- terized by repetitive episodes of complete or partial upper-airway ob- struction occurring during sleep. OSA is associated with several neg- ative health effects. Hypertension (Peppard, Young, Palta, & Skatrud, 2000; Calhoun, 2010), diabetes (Rasche, Keller, Tautz, Hader, Hergenc, Antosiewicz, et al., 2010), increased mortality and cardiovascular disease © Perceptual & Motor Skills 2014 2014, 118, 2, 571-586. 1 Address correspondence to Bjørn Bjorvatn, M.D., Ph.D., Department of Global Public Health and Primary Care, University of Bergen, Kalfarveien 31, N-5018 Bergen, Norway or e-mail (bjorn.bjorvatn@isf.uib.no).
