Behavior of cervical intraepithelial neoplasia in pregnant adolescents and its persistence after an obstetric event

Objective: To observe the behavior of cervical intraepithelial neoplasia in pregnant adolescents and the persistence before the delivery. Materials and Methods: A cross-sectional study including 47 pregnant adolescents with NIC-positive results diagnosed by colposcopy during pregnancy with subsequent evaluation before the delivery. Non-random sampling of consecutive cases. Descriptive statistics with central and dispersal measures. Results: In total, 156 pregnant adolescents were studied, of which 30% (n = 47) had positive results to NIC with subsequent evaluation. Ages 18 +/- 1.5 years, primiparous 77%, sexual activity initiation 15.6 +/- 1.6 years old, sexual partners 1 (1-6), smoking and alcoholism 21%. At the beginning of pregnancy, 98% had NIC I results and 2% had NIC II by colposcopy. After delivery, 13% had normal results and 87% remained in NIC I. Conclusion: The findings suggest that in pregnant adolescents there exists a natural dysplasia history as in pregnant women. Most of the lesions are NIC I and don't modify the evolution, with some regressing after the delivery.
