This study aimed to identify health problems and high-risk populations via an understanding of the practice of health behaviors, health literacy, and quality of life. This was an online, cross-sectional study conducted in September 2023. In total, 1520 (Chofu: n = 1170; Komae: n = 350) participants were enrolled. Participants' demographic characteristics, health literacy, health behaviors, and quality of life scores were obtained. Sleep quality was poor compared with national data. Younger participants had higher poor health literacy, did not practice health behaviors, and had a lower quality of life. In addition, parenting and informal nursing care for family members were associated with unhealthy eating, smoking, drinking, and poor quality of life. This study found that health problems and concerns before planning were significant in increasing the salience of interventions for community residents. Based on the findings of this study, an action plan for community-wide nursing practice was created.
