Pregnancy outcomes in urban teenagers.

Objectives: To compare pregnancy outcomes for teenagers with those for older gravidas. Methods: A retrospective case control study was undertaken to compare teenagers who delivered between January 1996 and October 1999 at a public urban hospital with a group of older gravidas. Results: Young pregnant teenagers were more likely to be nulliparous. They weighed less and gained less in pregnancy. More teen pregnancies occurred among Hispanics than other ethnic groups. The younger the teenager, the more likely for her infant to be of low or very low birth weight or growth restricted. There were fewer postmature deliveries, macrosomic fetuses and cesarean deliveries in young gravidas. Perinatal mortality was unaffected by maternal age. Conclusions: This investigation demonstrates that, while pregnancy outcomes in teenagers have improved in recent years relative to historical patterns, teenagers face continuing problems requiring special attention by care givers.
