In recent years, policies have been proposed to alleviate lifestyle-related diseases and to extend the human lifespan by improving urban environments. This research specifically analyzes the causal relation between the community environment and residents' physical and mental health. Therefore, this study applied a questionnaire about self-health awareness and physical health, community environment, daily routine, etc. Additionally, the research uses health indexes such as body mass index (BMI) and health-related quality of life (HRQOL) as evaluation standards. Results suggest the following. 1) An improved community environment, such as satisfactory public transportation system or public garden, tends to be non-obesity and foster a healthy mental state. 2) Health-awareness directly affects residents' physical and mental health.
