Objective: The objective of this study was to describe the prevalence and correlates of regular napping among older adults.
Methods: The National Sleep Foundation's "2003 Sleep in America Poll," a 20-minute telephone interview that focused on the topic of "sleep and aging" (N = 1,506 adults 5584 years of age).
Results: Overall, 15% of respondents reported regular napping, ranging in prevalence from 10% among those 5564 years of age to 25% among those 7584 years of age. In addition to older age and a strong association with excessive daytime sleepiness, other factors that independently increased prevalence included a diagnosis of depression, bodily pain, and nocturia.
Conclusions: Regular napping is common among older adults. Longitudinal studies of napping behavior and health status are needed to establish risk factors other than excessive daytime sleepiness.
Key Words: Aging naps sleepiness comorbidity depression nocturia
