Background: - Postterm pregnancy is defined as a pregnancy that persists beyond 294 days orrn42 weeks of gestation [1, 2]. The incidence of postterm pregnancy is approximately 7% [3]. Post-rnterm pregnancy is associated with significant risks to the pregnant woman, including laborrndystocia (9-12% versus 2-7% at term), severe perinatal injury related to macrosomia (3.3%rnversus 2.6% at term), doubling in cesarean delivery rate with associated endometritis, PPH andrnthrombophlebitis [5]. Because of the accompanying maternal and fetal complications differentrncenters adopt different strategies to avert these complications.rnHence, identification of postterm pregnancy before delivery by assessing risk factors, accuraterndating and proper management plays crucial role in preventing perinatal complications andrnresults in better obstetric outcome.rnObjective: - to assess perinatal mortality and feto-maternal morbidities related to post-termrnpregnancy.rnMethods: - this was a hospital based unmatched case control study. The cases were posttermrndeliveries in the three AAU teaching hospitals that fulfill inclusion criteria, and controls werernterm deliveries one before and one after the cases (1:2 proportions) and fulfill inclusion criteria.rnData was collected by interns and residents who were assigned in each hospitalâ€™s labor wardrnduring the working and duty hours in the study period. The principal investigator supervised therndata collection for the utmost quality. All postterm mothers who gave birth and those mothersrnwho gave birth at term and registered just above and below the selected cases in the specifiedrntime period that fulfill the inclusion criteria were included. All the necessary information for thernstudy were filled to a prepared structured format from the patients chart and interview. Datarnentered and cleaned using SPSS version 21.0 software. Analysis was done using chi-square testrntaking P
