Diabetes mellitus is a group of metabolic disorders characterized by hyperglycemia. Intakes of vitamin C, Magnesium, Chromium, fiber and physical activity can help normalizing blood glucose level so as to prevent hyperglycemia. The aim of this study is to find out particular relations between vitamin C, Magnesium, Chromium, fiber, as well as physical activity and blood glucose levels in patients with diabetes mellitus at Dr. M. Yunus Hospital Bengkulu. This study was cross sectional approach. Sample population is Diabetes Mellitus Type II. Sampling is performed using purposive sampling with 50 samples. Intake data were obtained through 2 x 24 hours food recall form and PAL form. Data were analyzed using correlation regression and multiple linear regression. There were significant correlations between intakes of vitamin C (p = 0.001), Magnesium (p = 0.027), fiber (p = 0.028), physical activity (p = 0.001) and random blood glucose levels in patients with Diabetes Mellitus Type II. Conversely, there was no significant correlation between Chromium intake (p=0421) and blood glucose levels in patients with Diabetes Mellitus Type II. The most dominant factors associated with blood glucose level in this study were vitamin C intake and physical activity.
