Incidence of cervical intraepithelial lesions in a population of adolescents treated in public health services in Rio de Janeiro, Brazil
This study aimed to estimate the incidence and types of cervical cytopathological findings in adolescents who were treated in public health services between 1993 and 2006. This is a cohort study, with the following inclusion criteria: < 20 years of age, sexually-active, without cervical lesions u...

| Resumo: | This study aimed to estimate the incidence and types of cervical cytopathological findings in adolescents who were treated in public health services between 1993 and 2006. This is a cohort study, with the following inclusion criteria: < 20 years of age, sexually-active, without cervical lesions upon entry into the study or sexually active < 1 year. The data were collected from 403 adolescents' medical records. Incidence density of cytopathological alterations was estimated and the actuarial method was used to calculate the 5-year incidence during follow-up after sexual initiation. In the first year of sexual activity, the incidence of cervical lesions was 24.1%. The incidence decreased to 3-8% over the following 4 years. The incidence density was 4.7 cases per 100 persons per year. The first abnormal cytological diagnosis showed atypical squamous cells of undetermined significance (ASCUS) in 5.5% (22) of patients, low-grade squamous intra-epithelial lesions (LSIL) in 28% (113), and high-grade squamous intraepithelial lesions (HSIL) in 3% (12). Eight (67%) cases of HSIL occurred during the first year of sexual activity. The incidence of cytopathological findings at beginning of sexual life is high, suggesting the importance of including sexually-active adolescents in cervical cancer prevention programs. |
