ABSTRACT
PURPOSE: The purpose of this study was to investigate the relationship of sleep quality, lifestyle and successful aging in the elderly. METHODS: The subjects of this study were 125 elderly people, aged 65 years and older, who attended a senior welfare center in Cheongju city, Korea. They completed a structured self-reported questionnaire comprising measures of quality of sleep, lifestyle, and successful aging. Data were analyzed using t-test, ANOVA, Scheffé's test, Pearson's correlation coefficient, and hierarchical linear multiple regression analysis with SPSS/WIN 20.0. RESULTS: Lifestyle showed a positive correlation with the quality of sleep, and successful aging showed a significant positive correlation with quality of sleep and lifestyle. Pin money (β=.32), quality of sleep (β=.20) and lifestyle (β=.55) were strong influential factors in successful aging. Hierarchical multiple regression analysis showed the determinant variables account for 35.9% of the variation in successful aging (F=35.11, p < .001). CONCLUSION: Successful aging depends on controllable factors such as the willingness to change the lifestyle of choosing one's life and how one copes with applying appropriate sleep hygiene. These results suggest that improvement of the quality of sleep and lifestyle will be helpful to the successful aging process.
