Aims & Objective: To determine the effect of age in women going through pregnancy and the obstetric outcome. To observe the gravity of antenatal care needed. Method: A retrospective study between two extremes of maternal age conducted from Jan 2015- June 2017. The obstetric outcome between teenage pregnancy (age <20yrs) and elderly pregnancy (>35yrs) were analysed. Results: The study showed a total of 3139 of. Deliveries out of which 219 were elderly pregnancies and 45 were teenage pregnancies. It showed a increased risk in caesarean section, eclampsia , diabetes in elderly gravidas and an increased risk of preterm labour, premature rupture of membranes, intrauterine fetal growth restriction, anaemia in teenage pregnancies with effective role of antenatal care in both the extremes. Conclusion: Pregnancy in both the extremes of age is a high risk so for good maternal and fetal outcome vigorous antenatal surveillance is a must for best results.
