The obstetric implications of teenage pregnancy.

A retrospective review was performed on the obstetric outcome of teenage pregnancies delivered in 1 year in a tertiary centre. The results were compared with the rest of the obstetric population in the same hospital in the same year. The teenage mothers (n = 194) had increased incidence of sexually transmitted diseases (5.2 versus 1.0%, P < 0.05), and preterm labour (13.0 versus 7.0%, P < 0.01), but decreased incidence of gestational glucose intolerance (3.1 versus 11.4%, P < 0.001), when compared with the non-teenage mothers (n = 4914). There was no difference in the types of labour, while the incidence of Caesarean section was lower (4.1 versus 12.6%, P < 0.001) in the teenage mothers. Although the incidence of low birthweight was higher in the teenage mothers (13.5 versus 6.5%, P < 0.001), there was no significant difference in the mean birthweight, gestation at delivery, incidence of total preterm delivery, or perinatal mortality or morbidity. The results indicate that the major risk associated with teenage pregnancies is preterm labour, but the perinatal outcome is favourable. The good results accomplished in our centre could be attributed to the free and readily available prenatal care and the quality of support from the family or welfare agencies that are involved with the care of teenage mothers.
