Objectives

To determine the association between objectively measured sleep and subsequent placement in a nursing home or a personal care home.

Design

Prospective cohort.

Setting

Participants' homes and sites of the Study of Osteoporotic Fractures.

Participants

One thousand six hundred sixty-four community-dwelling women with a mean age of 83 ± 4.

Measurements

At baseline, participants completed an average of 4 nights of wrist actigraphy; they provided data on place of residence at baseline and at follow-up, 5 years later.

Results

At baseline, participants had a mean total sleep time of 408 ± 72 minutes, mean wake after sleep onset of 71 ± 43 minutes, and mean sleep efficiency of 79 ± 11%. At follow-up, 71 (4%) were residing in a nursing home, and 127 (8%) were in a personal care home. Women with the most wake after sleep onset (by quartile) had more than twice the odds as those with the least of placement in a nursing home (adjusted odds ratio (AOR) = 2.94, 95% confidence interval (CI) = 1.34–6.44) or a personal care home (AOR = 2.33, 95% CI = 1.26–4.30). Similarly, women with the lowest sleep efficiency had more than three times the odds as those with the highest of nursing home placement (AOR = 3.25, 95% CI = 1.35, 7.82) and more than twice the odds of placement in a personal care home (AOR = 2.38, 95% CI = 1.33, 4.24). There was no association between sleep duration and placement.

Conclusion

In very old community-dwelling women, greater wake after sleep onset and lower sleep efficiency are risk factors for placement in a nursing home or personal care home. Sleep duration alone does not appear to increase the risk of placement in these long-term care settings.
