| Summary: | 碩士 === 長庚大學 === 護理學系 === 101 === The purpose of this study was to investigate the quality of sleep and its influences on quality of life and objective health indicators for senior residents in a retirement community. This study used cross-sectional descriptive correlational approach. The participants aged 65 or older, and were cognitive intact without disability. Instruments used in this study included demographic information, self-care abilities scale (Activities of Daily Living, ADL; Instrumental Activities daily Living IADL), Geriatric Depression Scale (GDS), Pittsburgh Sleep Quality Index (PSQI) and quality of life scale (WHOQOL-BREF Taiwan version), and the objective indicators included physical body composition and peripheral circulation.
A total of 76 participants were recruited. However, 3 of them were excluded due to missing out two questions on the “Quality of Life- Social Domains.” Therefore, a total of 73 participants were analyzed in this study. The results found that the average score of sleep quality was 6.52 (SD = 3.52), and 52.06% of them had poor sleep quality. Higher sleep quality score was related with lower IADL, more depression symptoms, lower overall quality of life and lower physical and psychological QOL, and higher venous efficacy (left). Stepwise regression analysis found that predictors of better quality of life were older age, female, better ADL, less depressive symptoms and better sleep quality. These predictors can explain the variance in overall and all aspects of quality of life (ranged from 19% to 40%). The depressive symptoms and sleep quality could explain 31% of the variances in overall quality of life that more depressive symptoms and poorer sleep quality predicted poorer overall quality of life. At the same time, more depressive symptoms, poorer ADL, and poor sleep quality predicted lower score for physiological aspect of quality of life and these predictors were able to explained 40% of the variance in physiological quality of life.
The results of this study suggest that the sleep quality is important to be assessed for elderly persons in the community. Related intervention, management and health education which aim to enhance sleep quality can be provided to promote the quality of life and decrease depressive symptoms for this population.
