Aim: To compare obstetric and perinatal outcomes of early and late teenage pregnancies of Omani nulliparous women with singleton pregnancies cared for and delivered at a tertiary teaching hospital. Method: In this retrospective study, we reviewed obstetric and perinatal outcomes of early teenage pregnancies (14–16 years), (n = 20) delivered at Sultan Qaboos University Hospital, Muscat, Oman, between 1 July 2006 and 30 June 2013 and compared their outcomes with outcomes of late teenage pregnancies (17–19 years), (n = 287) delivered at the same hospital during same period. Results: When compared with late teenage pregnant women, early teenagers were found to have no significant differences in prevalence of very preterm delivery <32 weeks (P = 0.62), preterm rupture of membranes (P = > 0.99), and anemia (P = 0.34). When compared to late teenagers, early teenagers had similar cesarean sections rates (P = >0.99), instrumental delivery rates (P = 0.56) and spontaneous vaginal delivery rates (P > 0.99). Both groups had similar birth weights (P = 0.87), low birth weights, (P = 0.55), and very low birth weights babies (P = 0.56 %). Perinatal mortality rate was similar in both groups. Conclusion: We may conclude that early teenage pregnant Omani women are not at increased risk of obstetric and perinatal complication compared to older teenagers.
