Perinatal outcome of teenage pregnancies in a selected group of patients.

Study Objective: To explore the effect of young age on the outcome of teenage pregnancies by studying teenage deliveries in our unique population.

Design, Setting, And Participants: Retrospective chart review of teenage gravidas (age 19 and younger), who had delivered in our hospital.

Outcome Measures: Mode of delivery, gestational age at delivery, newborn's weight and Apgar scores and maternal and neonatal complications.

Results: We recruited 565 teenage delivery cases from the hospital's computerized database. Mean maternal age was 18 (14-19). Most (96%) were married. Fifty-one percent were Jewish and 44% were Muslim. Most of the girls were nulligravidas. Mean gestational age at delivery was 39 weeks (33-44 weeks). A normal vaginal delivery ensued in 72.7%, while 9% had a cesarean section and 17.4% instrumental deliveries (compared to 85.75%, 10% and 4.25% in our adult population, respectively) and 1% underwent vaginal breech delivery. Mean birth weight was 3108 g (1450-4980 g). Apgar score of 9 at 5 minutes was recorded in 97.8% of the newborns. Prenatal care included a mean of 6 prenatal visits with a range of 1-18. The main complication was anemia; 41% had hemoglobin levels of less than 11 g/dL. The rate of other complications was low.

Conclusions: In our homogenous group of teenagers, there was a similar complication rate as in the adult population. The only significant complication was anemia (less than 11 g/dL). There was a higher rate of instrumental deliveries and the cesarean delivery rate was slightly lower than in our adult population. Teenage pregnancy should not be considered as a high-risk situation as long as it is planned and followed with the normal routines of prenatal care.
