Introduction: Teenage pregnancy is a serious problem all over the world and more so in developing countries like India, as early marriages and early pregnancy are the accepted cultural norms of our society. The present study aims to look at the incidence and maternal and foetal outcomes in teenage pregnant women in hospital visiting patients in Sion, Mumbai. Aim of the Study: To study incidence of teenage pregnancy and to study maternal and foetal outcome in this age group. Materials and Methods: This was a prospective study done over a period of two years. For all the antenatal cases complete history was taken. Antenatal course and labour management was observed and findings were noted. Intrapartum and post-partum course in the wards was studied. Various parameters were noted and analysed like incidence of pregnancy in teenagers, the marital status, age, parity, medical disorders, pregnancy related complications, incidence of malpresentations, mode of delivery, birth weight of babies and duration of hospital stay. Results: The incidence of teenage pregnancy was 6.45%. Most of the teenagers (85.1%) in the study were primigravida. The incidenceof preterm delivery among teenagers was higher (37.76%) than in the nonteenage patients (22.07%).The incidence of malpresentations was found to be higher in the teenage patients (4.3%) as compared to nonteenage patients (6.9%). Lower birth  weight babies and still births were more common in teenage pregnancies than in nonteenage pregnancies. Conclusion: The overall incidence of teenage pregnancy in the study was 6.45%. Most of teenagers were married and desirous of child bearing.Teenagers were predisposed to PIH, preterm labour and anaemia. Teenage mothers tolerated pregnancies well and there was no increase in operational intervention when compared to adult group.
