ABSTRACT The objective of this study was to describe the prevalence and correlates of regular napping among older adults.
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 55-84 years of age).
Overall, 15% of respondents reported regular napping, ranging in prevalence from 10% among those 55-64 years of age to 25% among those 75-84 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.
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.

    ABSTRACT: The objective of this study was to evaluate ethnic differences in the associations of nighttime sleep and daytime napping durations with prevalent type 2 diabetes. Samples of White (n = 908), Filipina (n = 330), and Black (n = 371) community-dwelling, postmenopausal women aged 50-86 years were evaluated with cross-sectional data obtained during 1992-1999 including self-reported duration of nighttime sleep and daytime napping, behaviors, medical history, and medication use. The prevalence of type 2 diabetes was evaluated with a 2-h 75-g oral glucose tolerance test. Overall, 10.9% of White, 37.8% of Filipina, and 17.8% of Black women had type 2 diabetes. Average sleep durations were 7.3, 6.3, and 6.6 h and napping durations were 16.8, 31.7, and 25.9 min for White, Filipina, and Black women, respectively. Sleep duration showed a significant (p < 0.01) nonlinear association with type 2 diabetes in Filipina women, with increased odds of diabetes at both low and high sleep durations independent of age, body mass index (BMI), triglyceride to high-density lipoprotein (HDL) ratio, hypertension, and daytime napping duration. Daytime napping duration was associated with type 2 diabetes only among White women; those napping ≥ 30 min/day had 74% (95% confidence interval (CI) = 10%, 175%) higher odds of diabetes compared to non-nappers independent of covariates including nighttime sleep duration. Results suggest ethnic-specific associations of nighttime sleep and daytime napping durations with type 2 diabetes. Copyright © 2014. Published by Elsevier B.V.

    ABSTRACT: Sleep/wake disturbance is a feature of almost all common age-related neurodegenerative diseases. Although the reason for this is unknown, it is likely that this inability to maintain sleep and wake states is in large part due to declines in the number and function of wake-active neurons, populations of cells that fire only during waking and are silent during sleep. Consistent with this, many of the brain regions that are most susceptible to neurodegeneration are those that are necessary for wake maintenance and alertness. In the present review, these wake-active populations are systematically assessed in terms of their observed pathology across aging and several neurodegenerative diseases, with implications for future research relating sleep and wake disturbances to aging and age-related neurodegeneration.
