<![CDATA[Diabetes Mellitus (DM) is a chronic disease with an increasing prevalence and a high risk of serious complications. Efforts to prevent complications are strongly influenced by patient behavior, which is partly determined by the level of knowledge. This study aimed to analyze the relationship between knowledge level and complication prevention behavior among patients with DM at Daruba Primary Health Center. This study employed a quantitative design with a cross-sectional approach. A total of 43 respondents were selected using purposive sampling. Data were collected using questionnaires measuring knowledge level and complication prevention behavior, and were analyzed using the chi-square test with a significance level of 0.05. The results showed that most respondents had moderate to good knowledge and moderate levels of complication prevention behavior. Bivariate analysis revealed a significant relationship between knowledge level and complication prevention behavior among DM patients (p < 0.05), indicating that respondents with better knowledge tended to have better preventive behavior. In conclusion, there is a significant relationship between knowledge level and complication prevention behavior among patients with Diabetes Mellitus. Adequate knowledge plays an important role in promoting optimal self-care behavior. Therefore, healthcare providers at primary health centers are expected to enhance structured and continuous education programs to improve patient knowledge and prevent complications. Improving knowledge is essential to promote complication prevention behavior in DM patients. Structured education is needed to improve knowledge and preventive behavior among DM patients.]]>
