<![CDATA[The development of non-communicable diseases, especially diabetes mellitus, shows a significant increase in urban areas due to changes in lifestyle and social determinants of health. Purpose: This study aims to analyze the relationship between knowledge, attitude, lifestyle, and education level with diabetes mellitus prevention behavior and to formulate an effective community-based health promotion model in urban areas. Method: This study used a quantitative approach with a cross-sectional design on 300 respondents selected through a simple random sampling technique. Data were collected using a structured questionnaire that had been tested for validity and reliability, then analyzed using the chi-square test and odds ratio (OR). Result: The results showed that all independent variables had a significant relationship with diabetes mellitus prevention behavior (p < 0.05). Lifestyle was the most dominant factor (OR = 3.75), followed by knowledge (OR = 2.75), attitude (OR = 2.35), and education level (p = 0.010). However, a gap was found between the level of knowledge and the implementation of preventive behavior in the community. Implications: These findings underscore the need for health promotion interventions that focus not only on increasing knowledge but also on lifestyle changes through a participatory and contextual community-based approach. Conclusion: An integrative and adaptive community-based health promotion model that adapts to the characteristics of urban communities has the potential to increase the effectiveness of diabetes mellitus prevention in a sustainable manner.]]>
