Objectives: This study was performed to investigate the level of quality of life (QOL) and to identify its related factors among the elderly using a hall for the aged. Methods: The study subjects were 350 elderly people living in Nam Gu, Gwangju City. They were interviewed by questionnaire to collect information on social-demographic characteristics, health behaviors, health-related characteristics and QOL. We used statistical analysis methods such as T-test, ANOVA and multiple regression analysis to find which factors affected QOL. Results: The characteristics relating to physical functions were as follows: presence of spouse, education, alcohol drinking, teeth condition, arthritis, frequency of visiting the hall for the aged, and depression. Age, arthritis and depression were significantly related to role limitation due to physical problems. General health was related to gender, age, and depression, and vitality was related to education, frequency of visiting the hall, and depression. Role limitation due to emotional problems was related to age and depression, and mental health was related to age, hypertension, arthritis and depression. Conclusions: This study showed QOL of the elderly was significantly influenced by socio-demographic factors, and physical or emotional conditions. To improve QOL of the elderly, we need to develop programs to promote health and to manage chronic diseases of the elderly.
