Treatment and Follow-up of Human Papillomavirus Infected Women in a Municipality in Southern Brazil

Prevalence and factors associated to cervical changes in units from the Single Health System

OBJECTIVE

To estimate the prevalence and risk factors associated with cytopathological changes in the uterine cervix of women treated by the Unified Health System.

METHOD

This is a cross-sectional study carried out with 350 women, between 14 and 79 years old who underwent pap smear tests in heath units in Francisco Beltrão, Paraná. Cervical cytopathological analyses and a questionnaire were applied to obtain socioeconomic information, as well as data on sexual behavior, gynecological aspects, and life habits. Chi-square test and logistic regression with p <0.05 were applied for statistical analysis.

RESULTS

The prevalence of cervical changes was 3.4% and the main categories found were low-grade cervical intraepithelial lesion, high-grade cervical intraepithelial lesion, and atypical cells of undetermined significance. From these, the first were present in 16.6% of women under 25 years old. The multivariate analysis pointed at associations between previous results of the cytopathology test (OR = 25.693), smoking (OR = 7.576), and oral contraceptives (OR = 5.265) and the outcome.

CONCLUSION

Women with a history of previous cervical cytopathological abnormality, use of oral contraceptives, and smokers were more likely to have an abnormal result in the pap smear test.
