BackgroundrnDiabetesmellitus is one of the endocrine disorders worldwide. It is estimated that, at the time ofrndiagnosis of type 2 diabetes mellitus, more than 10 % of patients have one or two risk factors for footrndisease, such as peripheral neuropathy or peripheral vascular disease. The burden of diabetic footrndisease is expected to increase given the increasing global prevalence of diabetic foot ulcer Worldwide,rn3 %–10 % of people with diabetes have a foot ulcer; the lifetime risk for developing is 15 %. Rates ofrnfoot ulceration in Africa vary between regions and have been estimated to be between 4 % andrn19 %.Associated factors apart from as peripheral neuropathy or peripheral vascular disease , barefootrnwalking, inappropriate footwear, poor foot hygiene and delay in seeking medical care .rnObjective: To assess prevalence of diabetic foot ulcer and associated factors at TikurAnbessarnSpecialized Hospital, Addis Ababa, Ethiopia, 2017.rnMethods and Analyses: - An institution based cross sectional quantitative study design was conductedrnfrom April 1st to May 1st 2017. TikurAnbessa Specialized Hospitalwas selected purposively. Sample sizernwas calculated by using single population proportion sample formula and the final sample size was 203.rnStudy subject were selected using simple random sampling method. Data was checked for completeness,rncleaned, coded and entered into EPI data version 3.1and analyzed using SPSS version 22.0. Descriptivernstatistics, frequency, proportion, mean and SD was used to describe variables. Binary logistic regressionrnand multivariate regression including odds ratio with 95%CI was used to identify association betweenrndependent and independent variables. P-value less than 0.05 were considered as significance level forrnassociations.rnResult: The prevalence ofdiabetic foot ulcer cases among diabetic patient was 26%. Of the 198rnrespondents, 106 (53%) were males with the remaining females. Occupation {(AOR=8.16; CI (1.2,rn9.5)} and place of place residence {(AOR=5.97; CI(1.47, 24.3)} was significantly associated withrndiabetic foot ulcer.rnConclusion and Recommendation: The study revealed that the prevalence of diabetic foot ulcer amongrndiabetic patients in TikurAnbesa specialized Hospital was twenty six percent. Place of residence andrnoccupation was associated with diabetic foot ulcer. There is a need to design and iintervention to reducernthe incidence of diabetic foot ulcer.rnKeyword: diabetic foot ulcer, prevalence
