Objective: Determining the frequency of predisposing factors for obstetric anal sphincter injury in Pakistani women in Shalamar Hospital, Lahore.Material and Methods: A Cross Sectional study carried out in Obstetrics and Gynaecology department, Shalamar Hospital, Lahore from 2nd December 2020 to 30th June 2021. 136 women underwent spontaneous vaginal delivery were included in the study. Patients were evaluated and factors leading to obstetric anal sphincter injury were recorded on especially designed proforma.Results: 18 to 40 years patients with mean age of 27.801±2.41 years and mean weight was 64.544±5.24 Kg. Factors predisposing to obstetric anal sphincter injury were primiparity 51.5%, gestational diabetes 5.1%, induction of labour 22.8%, episiotomy 71.3% and macrosomia in 16.2% of the cases.Conclusion: we concluded that primiparity, episiotomy, birthweight of the neonate and head circumference of the neonate lead to the increased incidence of obstetric anal sphincter injury among Pakistani women.
