Abstract

Epidemiological data indicate that sleep complaints increase with age. In this study, sleep-wake patterns of the frail elderly were clarified and the factors related to them were analyzed. The subjects were 76 elderly people in a long-term care hospital. Fifty-nine day's sleep-wake patterns were examined through a sleep log recorded by nurses and care workers. The relationship between sleep parameters and sleep-related factors was analyzed. Factors of age, Barthel Index, HDS-R, and frequency of participation in activity care programs were related to the sleep parameters. Results of multiple linear regression analysis revealed that most sleep parameters were influenced by the factor of frequency of participation in activity care. Following this investigation, the effects of activity care on sleep-wake patterns of the frail elderly were examined. The participants were 9 elderly people without dementia and 8 elderly females with dementia. Thirty day's sleep-wake patterns of the participants were examined, and then activity care programs were planned and implemented. Afterwards, 36 or 30-day sleep-wake patterns of the participants were recorded. There was a significant increase of total sleeping hours after the intervention. These findings indicated that there were positive effects of activity care intervention on the sleep-wake patterns of the frail elderly.
