[Non adherence to cancer screening guidelines for cervical cancer among women who attended prenatal care].

PURPOSE
To estimate the prevalence and identify the factors associated with delayed pap smear test of the cervix (carried out more than three years ago) among mothers with sons under two years of age, who attended the prenatal care.


METHODS
Cross-sectional, population-based household survey. Women with sons under two years old, living in the northern area of the city of Juiz de Fora (MG), Brazil, were interviewed. Stratification and clustering were used in a complex sampling procedure. We applied a survey questionnaire to capture women's demographic and socioeconomic characteristics of women and information about prenatal and practices for preventing cancer of the cervix. For statistical analysis of the possible bivariate association of factors, we used χ² test and a logistic regression model with the explanatory variables that had a significance less than or equal to 0.05 in the bivariate analysis.


RESULTS
We found a delayed test prevalence of 26.6% (95%CI 21.3 - 32.6), including women who were never submitted to the exam. The variables associated with the non-adherence to the examination within the stipulated time were: to be married (OR 0.5; 95%CI 0.2 - 0.9), and divorced/widowed (OR 0.1; 95%CI 0.02 - 0,8), having performed gynecological examination in prenatal care (OR 0.3; 95%CI 0.1 - 0.6) and number of prenatal visits (OR 0.09; 95%CI 0.03 - 0.25 for more than 11 visits), being all protection factors.


CONCLUSIONS
The prevalence of adherence to Pap smear guidelines is slightly lower than the percentage recommended by the World Health Organization. Apart from that, the fact that the woman was submitted to the prenatal care did not guarantee the adherence to Pap smear frequency guidelines.
