Abnormal cervical cytology in pregnant adolescents.

A retrospective, cohort study of pregnant adolescents with abnormal cervical cytology including: atypical squamous cells of undetermined significance (ASCUS), low-grade squamous intraepithelial lesions (LSIL) and high-grade squamous intraepithelial lesions (HSIL) was done to determine the regression, persistence and progression of abnormal cervical cytology in adolescent pregnancies. Follow-up cervical cytology within 1 year was assessed. Results suggest that pregnant adolescents have a high regression rate of abnormal cervical cytology. The likelihood of regression, persistence, or progression, is independent of the initial cytological diagnosis.
