Excessive Daytime Sleepiness and Associated Factors in Military Search and Rescue Personnel.

Abnormal excessive daytime sleepiness (EDS) has been reported worldwide, but too little is known about EDS and its determinants in Search and Rescue (SAR) populations. We aimed to determine the prevalence of abnormal EDS and contributing factors among Royal Norwegian Air Force (RNoAF) SAR helicopter personnel. In this cross-sectional study, a total of = 175 RNoAF SAR personnel completed an electronic survey including socio-demographic and lifestyle questions.
