Background: Globally obstructed labor accounted for 8% of all maternal deaths. In Ethiopia, obstructed labor is associated with adverse maternal and fetal outcomes. Ethiopia is a multicultural country and there is significant variation in socio-demographic characteristics, delay in receiving quality care at health facilities, availability if supplies for emergency obstetric care. Although the particular challenges and complication of obstructed labor varies by settings. Objective: To assess prevalence of obstructed labor and associated factors among women who gave birth at public hospitals of South Gondar zone, North West Ethiopia. Methods: An institution-based cross-sectional study was conducted from February 10 tomarch 10, 2022 among women who gave birth at public hospitals of South Gondar zone.Systematic random sampling technique was used to select 381 study participants. Data were collected by using interviewer administered questionnaire and checklists. Data was entered in to Epi data version 3.14 and exported to SPSS version 25 for analysis. Bivariate and multivariable regressions were performed and adjusted odds ratio with its 95% confidence intervals was estimated to identify factors associated with obstructed labour. A p-value below 0.05 was used as a cut-off point for the significant association. Results:The prevalence of obstructed labour was 13.6% [95% CI: 10.1-16.8]. Mothers who had no ANC follow up [AOR =3.18, 95% CI: (1.54-6.56)], distance from the health facility greater than 50 km [AOR =3.97, 95 % CI (1.87-8.43)] and mothers can not able to read and write [AOR=4.85, 95 % CI (1.54-15.27)] were factors associated with obstructed labour. Conclusions and recommendation:This study revealed that there was still high prevalence of obstructed labor although the government has been making possible effort to prevent the problem. Factors like antenatal care follow up, Educational status and Distance to the Health facility were significantly associated with obstructed labour. Interventions should give emphasis on maternal education, utilization of antenatal care service and avail of maternal waiting home for those mothers come from distance more than fifty kilometers.
