Objectives: To assess the prevalence of diabetic foot ulcer (DFU) in Wad Medani, Gezira state, Sudan, and the duration of diabetes associated with it. Methods: The study was comprehensively based on primary data obtained via a longitudinal cross-section random sample of 400 patients with diabetic mellitus presenting with Aldarga. The data collection tool was a structured questionnaire. Core questions were on main dimensions: Sociodemographic variables and duration, type of diabetes. Data were analyzed with SPSS program version 20, using descriptive and inferential statistics, namely, frequency tables and graphs, Fisher Chi-square, exact test of association, and logistic regression. Results: The static profile of the participants indicated that genetic background is an important factor in contracting diabetic mellitus. The calculated prevalence rate was 16.6% (17.1% for males and 16.1% for females) with overall probability limits. The analyses of associations indicated that the number of variables in all three dimensions have significant association with the development of DFU. The logistic regression pinpointed two factors with significant odds to develop DFU, namely, the duration of diabetic last fasting blood glucose value and that the duration of the illness is notable. Conclusion: The result suggests extensive awareness programs to control the negative effect of prolonged duration of diabetic’s are necessary especially crucial aspect of monitoring the blood sugar level under strict medical supervision
