Japan’s aging population rate is increasing and healthy life expectancy has decreases by 10 years shorter than average life expectancy. The aim of this study is to determine the relationship among chronic disease, sleep quality, health-related quality of life (HRQOL), and activities of daily living in people over 55 years old who live in the community. Subjects were 161 persons aged 57 to 90 years who were treated with chronic disease in the outpatient department of the A hospital. Exclusion criteria included patients with dementia, cancer and severe heart disease. The survey evaluation questionnaires included the Pittsburgh Sleep Quality Index (PSQI), HRQOL by Short-Form 8 Health Survey (SF-8), and activities of daily living. Variables associated with quality of sleep, HRQOL in univariate analysis with p < 0.05 were entered into multivariate analysis using logistic regression with a stepwise forward selection procedure to determine independent variables and their association with major causes. The logistic regression analysis was done using SPSS software and the post-hoc power of the study was estimated using G*power. The level of significance was set at p < 0.05. The risk factor of poor sleep quality was because of history of cancer [odds ratio (OR): 3.53, 95% confidence interval (CI): 1.06 - 11.77], and insomnia (OR: 3.25, 95% CI: 1.55 - 6.79). The risk factors of poor physical HRQOL were motor disease (OR: 2.62, 95% CI: 1.36 - 5.07), respiratory disease (OR: 3.24, 95% CI: 1.27 - 8.26) and having pain (OR: 11.71, 95% CI: 5.35 - 25.66). In addition, anemia was found to be a risk factor of poor mental HRQOL (OR: 4.87, 95% CI: 1.11 - 21.33). The feeling-for-their-body-age (OR: 0.30, 95% CI: 0.15-0.59) was as “younger than actual age” and advanced the risk factor of poor sleep quality. In addition, feeling-for-their-age (OR: 0.44, 95% CI: 0.21 - 0.92) resulted in reduced risk factor of poor physical HRQOL. The risk factor of poor sleep quality was due to a patient with history of cancer. The factor for good sleep quality and the good factor for physical HRQOL were indications of feeling younger than the actual age.
