This article delves into the issue of inequity in global healthcare access and emphasizes the importance of interdisciplinary collaboration in healthcare delivery models. It highlights the Healthy Cities model, focusing on the "Healthy Communities" approach by the Centers for Disease Control (CDC). Successful initiatives in public health should prioritize the community as the central unit of analysis. However, many existing studies fail to consider the unique community factors that affect the success of public health endeavors. This article addresses this crucial but often overlooked issue by examining the sustainable development of community health initiatives based on the Healthy Cities model. It specifically investigates the factors that contribute to the successful and sustainable development of such initiatives in various urban environments. The case study of Miami-Dade County serves as an illustrative example. By analyzing secondary sources, observational data, and conducting semi-structured interviews with programmatic leaders and stakeholders, this study reveals a paradigm that can be applied to different settings, aiding in the formulation of successful and sustainable community health initiatives.
