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.

    • "Optogenetic stimulation of these neurons increases the probability of a transition from sleep to wake (Adamantidis et al. 2007), and their silencing induces sleep (Tsunematsu et al. 2011). Consistent with a loss of wake consolidation with aging (Foley et al. 2007), substantially decreased numbers of orexin neurons have been observed in aged rats (Kessler et al. 2011) and mice (Brownell and Conti 2010), and the remaining neurons have decreased signs of activation following sleep deprivation (Naidoo et al. 2011). Moreover, orexin signaling in downstream wakeactive regions is diminished in several animal models. "

    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.

    • "To our knowledge, no study has included a sample of Filipinos, a group with a disproportionately high diabetes prevalence compared to both Whites and Blacks [15]. Although less studied, daytime napping, which is common among older adults, has also been linked to poor health outcomes including diabetes [16] [17] [18] [19]. However, the majority of these studies have been conducted in Chinese populations, and it is currently unknown whether the relationship between daytime napping and diabetes may differ by ethnicity. "

    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.

    • "Meanwhile, there is limited evidence from the British population. Although daytime napping has not been a tradition among British adults, the prevalence of napping is likely to increase with the rapidly aging population (17, 18), and it is therefore important to understand the health associations of daytime napping among the British.

    ABSTRACT: Epidemiologic studies have reported conflicting results on the relationship between daytime napping and mortality risk, and there are few data on the potential association in the British population. We investigated the associations between daytime napping and all-cause or cause-specific mortality in the European Prospective Investigation Into Cancer-Norfolk study, a British population-based cohort study. Among the 16,374 men and women who answered questions on napping habits between 1998 and 2000, a total of 3,251 died during the 13-year follow-up. Daytime napping was associated with an increased risk of all-cause mortality (for napping less than 1 hour per day on average, hazard ratio = 1.14, 95% confidence interval: 1.02, 1.27; for napping 1 hour or longer per day on average, hazard ratio = 1.32, 95% confidence interval: 1.04, 1.68), independent of age, sex, social class, educational level, marital status, employment status, body mass index, physical activity level, smoking status, alcohol intake, depression, self-reported general health, use of hypnotic drugs or other medications, time spent in bed at night, and presence of preexisting health conditions. This association was more pronounced for death from respiratory diseases (for napping less than 1 hour, hazard ratio = 1.40, 95% confidence interval: 0.95, 2.05; for napping 1 hour or more, hazard ratio = 2.56, 95% confidence interval: 1.34, 4.86) and in individuals 65 years of age or younger. Excessive daytime napping might be a useful marker of underlying health risk, particularly of respiratory problems, especially among those 65 years of age or younger. Further research is required to clarify the nature of the observed association.
