Introduction: Diabetic foot disease is a growing major public health problem and the leading cause of prolonged hospital admission, health-related costs, and reduced quality of life for diabetes patients. This study aimed to determine the prevalence of diabetic foot ulcers (DFU) and its associated factors among type 2 diabetes patients in Harari Region, East Ethiopia. Methods: An institution-based retrospective study was conducted from 28 March to 30 April 2018, among type 2 diabetes patients diagnosed between 1 January 2013 and 31 December 2017, at three government hospitals of Harari Region. Data were collected using a standard checklist format. Data were entered into Epi Info Version 7 and analyzed using SPSS 24. Binary and multiple logistic regression models were used to determine the associated factors. Odds ratio with 95% confidence intervals was used to determine level of association. Result: A document of 502 type 2 diabetes patients was reviewed and included in the final analysis in this study. The prevalence of DFU among type 2 diabetes patients was 21.1%. Being currently married decreased the odds of DFU by 60% (adjusted odds ratio = 0.40; 95% confidence interval: 0.17–0.96). Factors associated with increased diabetes ulcers chance were physical inactivity 2.29 (adjusted odds ratio = 2.29; 95% confidence interval: 1.17–4.48), starting treatment with insulin 4.43 times (adjusted odds ratio = 4.43; 95% confidence interval: 1.84–10.67), obesity 27.76 (adjusted odds ratio = 27.76; 95% confidence interval: 13.96–55.23), delay to start follow-up 2.22 (adjusted odds ratio = 2.22; 95% confidence interval: 1.03–4.82), history of infection 3.50 (adjusted odds ratio= 3.50; 95% confidence interval: 1.83–6.69), and hypertension 3.99 (adjusted odds ratio = 3.99; 95% confidence interval: 2.08–7.65). Conclusion: The prevalence of DFU among type 2 diabetes is substantially high as more than one in five patients have this complication. Moreover, marital status, physical activity, baseline medication, obesity, delay for follow-up, infection history, and hypertension were significantly associated with the development of DFU.
