Twin pregnancy in adolescents.

We compared the outcome of twin pregnancies born to adolescent versus adult gravidas. Five hundred forty-seven sets of twins were delivered during a 6-year period, 50 to adolescents and 395 to adults between 20-34. There were no significant differences in mean length of gestation, birth weight, or perinatal mortality. Maternal age was not a predictor of birth weight in twins. These findings suggest that twins born to adolescent gravidas do not experience significantly more unfavorable pregnancy events.
