Purpose: This study aimed to identify the relationships among life satisfaction, activities of daily living, depression and health behavior in low income elderly living at home. Methods: Study participants were 455 elderly who were receiving home visit services from the Daegu Regional Office of Patriots and Veteran Affairs. Data were collected through personal interviews using questionnaires from July to August, 2010. Results: Average scores of ADL and IADL were 7.82 out of 21 and 12.67 out of 33 respectively, which indicate relatively independent to everyday life. Mean scores of depression, health behavior and life satisfaction were 8.61 out of 15, 88.14 out of 132 and 48.57 out of 60. There were significant relationships among the variables of life satisfaction, activities of daily living (ADL, IADL), depression and health behavior. A significant factor influencing life satisfaction was health behavior ($eta$=.134, p=.020).
