Association between sleep quality and living environment among Chinese older persons: a cross-sectional study
摘要
Sleep quality significantly affects the quality of life of older persons. Therefore, this study explored the relationship between sleep quality and living environment of older persons in China to provide a theoretical basis for therapies to alleviate sleep disorders in older persons. A total of 6211 subjects > 60 years of age in Anhui Province, China, were evaluated using the Pittsburgh Sleep Quality Index and a self-reported questionnaire. Multivariate logistic regression analysis revealed that living alone (OR = 1.26, 95% CI 1.09–1.46) and living in a rural area (OR = 1.19, 95% CI 1.06–1.34) were significantly associated with a high incidence of sleep disorders in older persons. Living near a park or foot paths suitable for exercise or walking was significantly associated with a lower incidence of sleep disorders in older persons (OR = 0.87, 95% CI 0.77–0.96). Individual factors such as female sex (OR = 1.30, 95% CI 1.14–1.48) and depression (OR = 2.80, 95% CI 2.47–3.19) were also associated with sleep quality in older persons. These data indicate a correlation exists between living environment and sleep quality.
