ABSTRACT To examine the association between sleep-related factors and measured and self-reported mobility in a representative sample of older adults.
This study included 2,825 men and women aged 55 years and older participating in a cross-sectional representative population-based Health 2000 Survey in Finland. Sleep duration, insomnia-related symptoms, and fatigue were inquired. Maximal walking speed was measured, and mobility limitation was defined as self-reported difficulties in walking 500 m or stair climbing.
Insomnia-related symptoms and fatigue were prevalent among persons aged 65 years and older in particular. After adjusting for lifestyle factors and diseases, longer sleep (>/=9 hours) was associated with a decreased walking speed in women aged 65 or more years (p = .04) and shorter sleep (</=6 hours) with a higher odds for mobility limitation in women aged 65 or more years (odds ratio [OR] = 1.68, 95% confidence interval [CI] = 1.02-2.75) and in men aged 55-64 years (OR = 3.62, 95% CI = 1.40-9.37) compared with those having a mid-range sleep duration. Sleeping disorders or insomnia was independently associated with both decreased walking speed and mobility limitation in men aged 55 or more years but only with mobility limitation in women aged 65 or more years. Of the sleep-related daytime consequences, "weakness or tiredness" was associated with a decreased walking speed and a higher odds for mobility limitation both in men and in women aged 55 or more years.
Several sleep-related factors, such as sleep duration, insomnia-related symptoms, and fatigue, are associated with measured and self-reported mobility outcomes.

    ABSTRACT: More than 50% of community-dwelling adults have sleep complaints. Because aging is associated with decline in physical function, coexistent sleep difficulties may exacerbate functional decline. This pilot study explored the relationships between sleep, age, chronic disease burden, and physical function among 50 community-dwelling older adults. Findings revealed significant relationships between total sleep time and preclinical disability (r = -0.33, P ≤ .05) and mobility difficulty (r = -0.36, P ≤ .05). A regression analysis showed that total sleep time was significantly associated with mobility difficulty and preclinical disability, even after controlling for chronic disease burden. These findings suggest that total sleep time may be a catalyst for functional decline.

    ABSTRACT: Objectives To determine how poor sleep affects the health of older ethnic minorities. DesignCross‐sectional study involving a population‐based survey. SettingHispanic Established Population for the Epidemiologic Study of the Elderly (H‐EPESE) survey conducted in the southwestern United States. ParticipantsTwo thousand two hundred fifty‐six Mexican‐American men and women aged 65 and older. MeasurementsThe association between self‐reported sleep problems and mortality over a 15‐year period in a population based sample of older Mexican Americans was examined. Using five waves of data (1993–2008) from the H‐EPESE, Cox proportional hazard models stratified according to sex were used to model the risk of death as a function of chronic sleep problems. ResultsHaving any sleeping problems during the last month was associated with greater risk of mortality (hazard ratio = 1.14, 95% confidence interval = 1.00–1.29) in unadjusted models, although the association was attenuated after accounting for covariates. Conclusions Similar factors explained the association between sleep and mortality in men and women: health behaviors, depressive symptoms, and health conditions. These factors are related to stress, and both may lead to poor sleep quality. Research is needed to better understand the factors moderating the relationship between sleep, mortality, and sex.

    ABSTRACT: Background Sleep disturbances and depression are costly and potentially disabling conditions that affect a considerable proportion of older adults. Purpose To test the effectiveness of six-months of elastic band exercises on sleep quality and depression of nursing home older adults in wheelchairs. Method 127 older adults from 10 nursing homes participated in this cluster randomized control trial, and 114 completed the study. Participants were randomly assigned to two groups: experimental group (five nursing homes, n = 59) and control group (five nursing homes, n = 55). A 40-minute Wheelchair-bound Senior Elastic Band (WSEB) exercise program was implemented three times per week for six months. Sleep quality and depression of the participants were examined at baseline, after three-month, and at the end of the six-month study. Discussion Participants in the experimental group had longer sleep durations, better habitual sleep efficiencies, and less depression than the control group at three months of the study and maintained them throughout the rest of the six-month study. Conclusions Nursing home directors could recruit volunteers to learn the program and lead the elderly residents in wheelchairs in practicing the WSEB exercises regularly in the facilities.
