Sound Sleep Patterns Keeps Seniors Out of Institutions

Sound Sleep Patterns Keeps Seniors Out of InstitutionsResearchers say fragmented or interrupted sleep is a predictor for placement of an elder into an assisted living or long-term care facility.

In the new study, investigators at the Johns Hopkins Bloomberg School of Public Health outline the association between objectively measured sleep and subsequent institutionalization among older women.

“Sleep disturbances are common in older people,” said Adam Spira, Ph.D, lead author of the study.

“Our results show that in community-dwelling older women, more fragmented sleep is associated with a greater risk of being placed in a nursing home or in a personal care home. We found that, compared to women with the least fragmented sleep, those who spent the most time awake after first falling asleep had about 3 times the odds of placement in a nursing home.

“Individuals with the lowest sleep efficiency—those who spent the smallest proportion of their time in bed actually sleeping—also had about 3 times the odds of nursing home placement.”

The authors found similar patterns of associations between disturbed sleep and placement in personal care homes, such as assisted-living facilities.

Interestingly, how long an individual sleeps, that is the sleep duration, did not predict placement in either of these settings.

According to the Centers for Disease Control and Prevention, insufficient sleep is associated with a number of chronic diseases and conditions—such as diabetes, cardiovascular disease, obesity and depression.

In addition, insufficient sleep is associated with the onset of many diseases and is responsible for motor vehicle and machinery-related crashes. Previous studies have also linked disturbed sleep with disability in older adults and impairment in activities of daily living and mobility.

Researchers used a prospective cohort study methodology to measure the sleep of women with a mean age of 83 years old from the Study of Osteoporotic Fractures.

Participants were asked to wear actigraphs, a device that records movements, for at least three days. Information garnered from the device can be used to characterize patterns of sleep and wake cycles.

Demographic information as well as place of residence at initial interview and at 5-year follow-up was also provided.

Although several prior studies had investigated the link between sleep disturbance and nursing home placement, those studies asked participants questions about sleep rather than collecting objective sleep data.

“Despite the growing literature on sleep disturbance and disability, prior to our research very little was known about the association between sleep disturbance in older adults and risk of placement in long-term care facilities.

“Greater sleep fragmentation is associated with greater risk of placement in a nursing home or personal care home 5 years later after accounting for a number of potential confounders,” said Kristine Yaffe, M.D., senior author of the study.

Spira adds, “It’s important to remember that this is an observational study, so our findings cannot demonstrate a conclusive causal link between sleep disturbance and placement in long-term care facilities.

“We need more research to explain how sleep disturbance might lead to this outcome, and whether interventions to improve sleep might prevent it.”

Their report is found in the Journal of the American Geriatrics Society.
