ObjectiveThis study aimed to determine the magnitude and associated factors of women’s awareness of obstetric fistula (OF).MethodsThis community based crossectional study was conducted among 15,683 reproductive-aged women. A multi-level multivariable logistic regression analysis employed. A 95% CI and p-value < 0.05 were used to declare statistical significance.ResultThe magnitude of women’s awareness of OF was 38% [95%CI: 0.37, 0.39]. Individual level variables such as being in the age group 20-25 [AOR=1.17; 95%CI:1.02, 1.35], 26-30 [AOR=1.50; 95%CI: 1.27, 1.76] and >30 [AOR=1.76; 95%CI: 1.50, 2.07], being Muslim religion follower [AOR = 0.83; 95%CI: 0.73, 0.94], attending primary education [AOR=1.70; 95%CI: 1.53, 1.89], attending secondary education [AOR=3.43; 95%CI: 2.95, 3.99] and attending higher education [AOR=5.88; 95%CI: 4.66, 7.42], history of pregnancy termination [AOR=1.31; 95%CI: 1.13, 1.51], media exposure at least once a week [AOR= 1.33; 95%CI: 1.2, 1.49], internet use [AOR= 2.25; 95%CI: 1.84, 2.75], medium house hold wealth [AOR=1.17; 95%CI: 1.02, 1.34], rich house hold wealth [AOR=1.50; 95%CI:1.31, 1.72] and community level factors including high community media exposure [AOR = 1.30; 95%CI: 1.05, 1.61], high community ANC rate [AOR=1.66; 95%CI: 1.37, 2.02] and low health facility distance problem [AOR=1.49; 95%CI: 1.23, 1.81] were significantly associated with awareness of OF.ConclusionThe magnitude of women’s awareness of OF was very low in Ethiopia. Maternal age, religion, being educated, media exposure, being from a wealthier household, low health facility distance problem, and high community ANC rate were significantly and positively associated factors with awareness of OF.
