Health-promoting behaviors improve health, prevent disease, and decrease healthcare costs. This study describes the health-promotion behaviors and identifies influencing factors of health-promoting behaviors in low-income patients at a community health center. This cross-sectional study used participants from a center serving a low-income population. Spiritual growth and interpersonal relations were the two most practiced health-promoting behaviors. Age and education influenced participation in health-promoting behaviors. Promoting spiritual growth and interpersonal relations is a critical part of supporting health-promoting behaviors. Findings provide guidance for nurses to contribute to increasing healthy behaviors and develop interventions to improve participation in health-promoting behaviors.
