<![CDATA[Background: Diabetes mellitus is a chronic metabolic disease characterized by elevated blood glucose levels due to impaired insulin secretion or action. Diabetes management can be achieved through dietary adherence and physical activity. Objective: This study aimed to determine the relationship between dietary adherence and physical activity with random blood glucose levels (RBG) in patients with diabetes mellitus. Methods: This research employed an analytical design with a cross-sectional approach. A total of 50 respondents were selected using purposive sampling. Data were collected using a dietary adherence questionnaire, a physical activity questionnaire, and random blood glucose level measurements. Results: The findings showed that 58% of respondents were non-adherent to diet, 62% had moderate physical activity, and 74% had high random blood glucose levels. Chi-Square test results indicated a significant relationship between dietary adherence and random blood glucose levels (p = 0.003), while physical activity showed no significant relationship (p = 0.144). Conclusion: Dietary adherence plays an important role in controlling blood glucose levels in patients with diabetes mellitus, whereas physical activity does not have a direct relationship with blood glucose levels. It is recommended that healthcare providers strengthen education on healthy diet, patients become more disciplined in adhering to dietary recommendations, and future research includes additional variables to obtain more comprehensive results.]]>
