To compare the obstetric outcome of teenage pregnancies with that of older women.
Retrospective chart review of singleton births > or =24 weeks' gestational age at the American University of Beirut from 1994 to 2003. Adolescents (<20 years) were compared to subsequently delivered women aged 25-30 years (controls), n=486 each.
Only 131 (27.0%) adolescents were <18 years. More adolescents were nulliparous (79.8 versus 17.9%; p<0.0001). Preterm delivery <37 but not <34 weeks occurred more frequently in cases (11.1 versus 5.8%, p=0.004). Pre-eclampsia was more commonly encountered (2.9 versus 0.6%; p=0.012) and mean predelivery haematocrit was lower in cases (30.6+/-3.3 versus 33.8+/-4.3%, p<0.001), but the incidence of gestational diabetes, placenta previa, abruptio placentae, breech presentation, or meconium-stained amniotic fluid were similar. Caesarean delivery was performed less frequently in cases (9.2 versus 14.0%; p=0.028), but primary caesarean and operative vaginal delivery rates were similar though vacuum was used more frequently in multiparous controls (0.2 versus 2.7%, p=0.011). Nulliparous cases had shorter first and second stages of labour (384+/-304 versus 524+/-339 min, p<0.0001 and 47+/-36 versus 63+/-50 min, p=0.002), respectively. Mean birth weight was higher in controls (3177+/-567 versus 3284+/-511 g, p<0.001), but intrauterine growth restriction, birth weight <2500 g, low Apgar scores, intrauterine fetal death, and stillbirths were similar in both groups.
Adolescents are more likely to deliver preterm than older women, and are more likely to suffer from anaemia and pre-eclampsia. Nulliparous adolescents have a quicker progress of labour while m
