Prevalence of excessive daytime sleepiness in a sample of the Australian adult population

The prevalence of EDS increased with age, affecting approximately one-third of those aged ⩾80 years. Because EDS has been associated with poorer health outcomes in the older age strata, these findings suggest that routine screening may be beneficial in ongoing health assessments for these individuals. Overall, more than one-tenth of the Australian adult population has EDS, which is indicative of possible underlying sleep pathology.
