[Adolescent primipara]

263 cases of adolescent primipara at Hospital de Ginecoobstetricia, at Garza García. N.L. from January to December, 1995, were reviewed. two groups were formed, one of 12 to 15 years with 79 (30.1%); and the other one of 16 to 18 years, with 184 (69.9%), (p < 0.05). There were significant differences in both groups, with a greater proportion in the first group (p < 0.05), as to free union and preterm pregnancy; less prenatal control in the young ones with 31.6% against 23.3% in complications during pregnancy, more frequent the first group 36.7% and 28.8%; being more frequent, in both groups premature rupture of membranes, followed by anemia, toxemia and prolonged pregnancy. In pregnancy resolution, cesarean section showed a significant difference in both groups, being more frequent in the first group with 55.7% against 34.4% (p < 0.01) and the main indication was cephalopelvic disproportion with 32.9% and 16.8%. As to weight of products only 5% and 6.5% were subnormal; in the Apgar at one minute. it was slightly low in the first group with two deaths prepartum in the group two. Maternal morbidity was greater in the youth with 5% against 1%; There were no maternal deaths. Perinatal morbidity/mortality was 8.8% and 11.4%, predominating in both groups. Retardation of intrauterine growth, and in group two, congenital malformations and two deaths, fetal, prepartum. The contraceptive method used was Intrauterine device postpartum with a frequency of 81% against 72.2%. It is concluded that the adolescent primipara should be considered as high risk, as there is an increase in maternofetal morbidity, being more intense in the younger ones, and that a prenatal control, adequate, is of a great benefit.
