Background: research on the association between habitual sleep duration and quality in older adults is scarce and has shown conflicting results. Moreover, no previous study has assessed the influence of health status on this association. Objectives: to examine the association between habitual duration and quality of sleep in older adults, and to test if this association varies with health status, as approximated by self-rated health, quality-of-life and functional limitation. Design: cross-sectional study with data collected by telephone interview. Setting: community-based study. Subjects: a total of 1,567 community-dwelling individuals aged ≥68 years in Spain. Methods: poor sleep quality was ascertained through nighttime complaints (sleeping-pill consumption, difficulty falling asleep, awakening during the night and early awakening), and daytime complaints (feeling unrested in the morning and daytime sleepiness). The analyses were adjusted for the main confounders, and were stratified by health status (self-rated health, health-related quality-of-life and functional limitation). Results: when compared with those sleeping 7-8 h, those who slept ≤6 h were more likely to report difficulty falling asleep [odds ratio (OR) 3.51; 95% confidence interval (CI) 2.37-5.20], frequent awakening during the night (OR 1.97; 95% CI 1.42-2.75), early awakening in the morning (OR 2.78; 95% CI 2.02-3.82) and feeling unrested in the morning (OR 1.73; 95% CI 1.18-2.54). Moreover, those who slept ≥9 h were more likely to report daytime sleepiness (OR 1.68; 95% CI 1.17-2.42). In stratified analyses, these associations generally did not vary with health status. Conclusions: in older adults, short sleep is associated with nighttime sleep complaints and feeling unrested in the morning, while long sleep is associated with daytime sleepiness.
Burden of disease due to sleep duration and sleep problems in the elderly
Sleep Health, 2018
Health-related quality of life (HRQOL) Objectives: The Centers for Disease Control and Prevention emphasizes conceptualizing sleep as a healthy behavior. Although a large literature exists documenting the morbidity or mortality of suboptimal sleep, fewer investigations have examined the burden of disease in a single number combining morbidity and mortality. This study examined the morbidity, as measured by health-related quality of life (HRQOL), mortality, and quality-adjusted life years (QALY) due to suboptimal (inadequate or excessive) sleep. Design and participants: We ascertained respondents' HRQOL scores and mortality status from the 2005 to 2008 National Health and Nutrition Examination Survey (NHANES) with mortality follow-up data through December 31, 2011 for respondents aged 65 and older (n = 2380). We estimated mean QALY according to duration of sleep, minutes to fall asleep, number of sleeping problems, and daytime impact. Results: More than one third of participants reported a suboptimal sleep duration. Short sleep duration had a greater adverse impact on morbidity, with reductions in HRQOL, while long sleep duration had a greater adverse impact on mortality. Compared to participants who reported between 7 and 9 hours of sleep per night, mean QALYs were significantly lower among participants who slept 10 or more hours a night (7.8 QALY; decrease of 9.8 QALY). Conclusions: This study confirmed the association between suboptimal sleep and greater burden of disease among the elderly US population. Our findings provide support for treating sleep as a healthy (health risk) behavior, thereby having implications for primary care providers and public health surveillance.
Sleep duration and health among older adults: associations vary by how sleep is measured
Journal of epidemiology and community health, 2015
Cohort studies have found that short and long sleep are both associated with worse outcomes, compared with intermediate sleep times. While demonstrated biological mechanisms could explain health effects for short sleep, long-sleep risk is puzzling. Most studies reporting the U shape use a single question about sleep duration, a measurement method that does not correlate highly with objectively measured sleep. We hypothesised that the U shape, especially the poor outcomes for long sleepers, may be an artefact of how sleep is measured. We examined the cross-sectional prevalence of fair/poor health by sleep hour categories (≤6, ≤7, ≤8, ≤9, >9 h) in a national US sample of adults aged 62-90 that included several types of sleep measures (n=727). Survey measures were: a single question; usual bedtimes and waking times; and a 3-day sleep log. Actigraphy measures were the sleep interval and total sleep time. Fair/poor health was regressed on sleep hour categories adjusted for demographic...

The aim of this study was to assess the relationship of sleep duration and all-cause mortality among 2,449 Polish community-dwelling older citizens of Krakow observed during 22 years of follow-up. In particular, the role of some demographic, psychosocial and health-related conditions were investigated in terms of modification effect. In the prospective study, background information was gathered by face-to-face interview. Vital data were obtained from the population registry. Cox regression models were used to assess the role of sleep duration in mortality, in the analyses of potential effect modifiers and the shape of the relationship. Sleep duration was observed to be a significant predictor of all-cause mortality. Lifeweariness, functional activity, total number of chronic diseases and age (65-79, 80?) were found to be effect modifiers for the relationship between sleep duration and mortality. Further investigation showed a U-shaped mortality risk associated with the duration of sleep among individuals with a high level of life-weariness, high functional activity and in individuals aged 80 and over. On the other hand, a linear relationship between longer sleep duration and mortality was observed among older people with no experience of life-weariness, without chronic diseases, with medium functional activity and aged 65-79, but also among those who reported three and more chronic conditions. Results of our study support available evidence showing the relationship between sleep duration and mortality among older adults and suggest that any public health intervention in this area should consider also other coexisting modifiable psychosocial and functional determinants.
Self-reported long sleep in older adults is closely related to objective time in bed
Sleep and Biological Rhythms, 2010
Although self-reported long sleep is associated with increased morbidity and mortality, little is known about the objective sleep patterns and daytime functioning of long sleepers, particularly those aged Ն50 years. Our primary aim was to compare the objective and subjective sleep patterns of a sample (n = 35) of middle-to older-aged adults who reported sleeping Ն8.5 h per night. A secondary aim was to characterize the mood and functioning of the sample. Over a 2-week period, sleep was recorded via actigraphy and a daily diary. Sleepiness was assessed daily. At the conclusion of the 2-week period, daytime sleepiness, mood, and quality of life were assessed. Measures of sleep and functioning were compared with available representative data. In the sample, actigraphic total sleep time (TST; 7.35 Ϯ 0.97 h) was approximately 60 min greater than age-related representative values but substantially less than diary-assessed TST (8.59 Ϯ 0.74 h) and survey-assessed TST (8.92 Ϯ 0.78 h). Survey and diary-based subjective TST assessments agreed more closely with actigraphic time in bed (TIB; 9.11 Ϯ 0.72 h) than TST, and correlations between subjective TST and actigraphic TIB were similar to those between subjective and actigraphic TST. Measures of mood, sleepiness, and daytime functioning were similar to population-representative values. These results suggest that, among middle-to older-aged adults, self-reported long sleep is primarily indicative of long TIB, but it also represents long objective sleep duration, particularly in comparison to age-matched data. Findings of little functional impairment corroborated previous descriptions of older long sleepers.
Sleep duration, health status, and subjective well-being
Revista de Saúde Pública, 2018
OBJECTIVE: To evaluate, in a population-based approach, the association of extreme sleep duration with sociodemographic factors, health, and well-being. METHODS: We analyzed the data from the 2014/2015 Health Survey in the city of Campinas, State of São Paulo, Brazil (ISACamp), performed with 1,969 individuals (≥ 20 years old). Associations between the independent variable and short (≤ 6 hours) and long (≥ 9 hours) sleep were determined using the Rao-Scott chi-square test. The analyses were adjusted with multinomial logistic regression models. RESULTS: Men, individuals aged 40 to 59, those with higher schooling, those who have one (OR = 1.47, 95%CI 1.02–2.12), two (OR = 1.73, 95%CI 1.07–2.80), or three or more (OR = 1.62, 95%CI 1.16–2.28) chronic diseases, and those with three or more health problems (OR = 1.96, 95%CI 1.22–3.17) were more likely to have a short sleep. The chance of long sleep was higher in widowers and lower in those who have more years of schooling, with higher inc...

Sleep duration and sleep quality are often linked to increased risk of mortality and morbidity. However, national representative data on both sleep duration and sleep quality and their relationship with chronic health problems are rarely available from the same source. This current study aimed to examine the independent and combined associations of sleep duration and sleep quality with physical and mental disorders, using data from the Singapore Mental Health Study 2016. 6,126 residents aged �18years participated in this epidemiological, cross-sectional survey. Sleep measures were assessed using the Pittsburg Sleep Quality Index while lifetime or 12-month medical and psychiatric diagnoses were established using the Composite International Diagnostic Interview 3.0. Both short sleep (<6hrs compared to 7-8hrs) and poor sleep were found to be independently associated with chronic pain, obsessive compulsive disorder and any mental disorder while poor sleep was additionally associated with major depressive disorder, bipolar disorder, generalized anxiety disorder and any physical disorder, when adjusted for confounders. Poor sleep combined with short sleep (�6hrs/day vs 7-8hrs/day) was associated with the highest number of comorbidities among other sleep combinations. Sleep duration and sleep quality, when adjusted for each other, remained independently associated with both physical and mental disorders. Affective disorders may be more closely related to poor sleep quality compared to abnormal sleep duration. Our findings suggest sleep quality to be a more important indicator for psychological and overall health compared to sleep duration.
The Association between Sleep Duration and Self-Rated Health in the Korean General Population
Journal of Clinical Sleep Medicine, 2013
Study Objectives: Sleep duration is recognized as one of the most common issues in modern society. Self-rated health is a commonly used subjective health measure based on a single question asking individuals to rate their general health on a four-or fi ve-point scale. However, few studies have examined the relationship between sleep duration and self-rated health. Here, we examined the association between sleep duration and poor self-rated health, using a large representative sample of the general Korean adult population. Design: We conducted a cross-sectional study of 15,252 participants in the Korea National Health and Nutrition Examination Survey IV (2007-2009) who were aged 19 years and older. Sleep duration was categorized as ≤ 5, 6, 7, 8, or ≥ 9 hours. The main outcome of interest was poor self-rated health (n = 3,705, 19.7%). Multiple logistic regression analysis was performed to examine the association between sleep duration and self-rated health. Results: We found both short (≤ 5 h) and long (≥ 9 h) sleep duration to be associated with poor self-rated health independent of sociodemographic, health risk, and health status variables. Compared with 7-h sleep duration, the multivariate odds of poor self-rated health were 1.358 times higher (95% CI 1.167-1.580) with short sleep duration and 1.322 times higher (95% CI 1.091-1.601) with long sleep duration. This association persisted in subgroup analyses of gender, body mass index, and age by gender. Conclusions: In a large representative sample of the Korean general adult population, compared with sleep duration of 7 hours, we found a positive association between short and long sleep duration and poor self-rated health in Korean adults. Furthermore, the association between sleep duration and poor self-rated health was consistently present in subgroups divided by gender, age, and BMI.
Sleep: a marker of physical and mental health in the elderly
The American journal of geriatric psychiatry : official journal of the American Association for Geriatric Psychiatry, 2006
The objective of this study was to determine the occurrence and recognition of common sleep-related problems and their relationship to health-related quality-of-life measures in the elderly. A total of 1,503 participants with a mean age of 75.5 (+/- 6.8, range: 62-100) years from 11 primary care sites serving primarily elderly patients were interviewed. Subjects completed a five-item sleep questionnaire and the SF-12. A Physical Component Summary (PCS-12) and Mental Component Summary (MCS-12) score was calculated. A systematic medical chart review was conducted to determine whether sleep problems were identified by the healthcare providers. A total of 68.9% of patients reported at least one sleep complaint and 40% had two or more. Participants most commonly endorsed (45%) that they had "difficulty falling asleep, staying asleep, or being able to sleep." The number and type of sleep problems endorsed was associated with both physical and mental health quality-of-life status...
Sleep
To report the distribution of various sleep parameters in a population-based study. Population-based cross-sectional study with self-administered questionnaires. Conducted as part of the Hordaland Health Study '97-'99 in collaboration with the Norwegian National Health Screening Service. 8860 subjects, aged 40 to 45 years, answered the sleep questionnaire part of the study. N/A. Reports on habitual bedtimes, rise times, subjective sleep need, and various sleep characteristics were used in this study. Mean (+/- SD) nocturnal sleep duration during weekdays in men was 6 hours 52 minutes (+/- 55 minutes); in women 7 hours 11 minutes (+/- 57 minutes). Mean subjective sleep need was 7 hours 16 minutes (+/- 52 minutes) in men; 7 hours 45 minutes (+/- 52 minutes) in women. Sleep duration was shorter in shift workers and longer in married subjects and in those living in rural areas. Subjective sleep need was higher in subjects reporting poor subjective health and in subjects living i...
