Purpose: This study aims to analyze the effect of the operation of community health centers that has been operated for the purpose of the sub-regional unit (dong unit) health promotion project to improve the low health indicators of Busan Metropolitan City, and to identify the difference in health behavior and health indicators according to the operation of community health centers in Area B, which currently shows a relatively low level of health in Busan Metropolitan City. This will not only allow us to examine whether community health centers has actually had a health effect on local residents but also to derive improvements in the operation of the centers. Methods: Using the secondary data from the Community Health Survey conducted by the Korea Disease Control and Prevention Agency, we examined whether the rate of walking practice, healthy lifestyle practice rate, smoking rate, high-risk drinking rate, stress complaint rate, depressive symptom hypertension diagnosis experience rate, diabetes diagnosis rate, and subjective health status differ depending on whether community health centers are operated or not. This will be used to check the changes in health indicators between 2015 (before the operation of community health centers) and 2020 (after the operation of community health centers). Result: Overall, when examining the changes between 2015 (before the operation of community health centers) and 2020 (after the operation of community health centers), the health indicators of the indicators of operating the community health centers in 5 out of a total of 9 indicators brought positive changes, and in 4 indicators, all of them were negative changes regardless of whether they were operating or not, but the extent of the negative change in the regions where community health centers were operating was very small compared to those that did not operate community health centers. Conclusion: Regions without community health centers still tended to show negative health status or worsening health levels. It is judged that the benefits to the residents can be greater if the operation of community health centers are expanded, so it can be said that various efforts are needed to expand the policy.
