[Cervical intraepithelial lesions in adolescents: cytological findings from 1999 to 2005 in Rio de Janeiro, Brazil].

The prevalence of cervical intraepithelial neoplasias has increased in adolescents, probably due to the decrease in age at first intercourse and increase in the number of sexual partners. Our objective was to analyze the trends in cervical intraepithelial lesions in adolescents in the city of Rio de Janeiro, Brazil. We thus conducted a retrospective analysis of 1,516,407 Pap smears performed at public health units from 1999 to 2005.
