Differential Impact of Education Level, Occupation and Marital Status on Performance of the Papanicolaou Test among Women from Various Regions in Brazil

Background: In Brazil, little is known regarding the underlying causes of differences among populations regarding socio-economic variables that affect women’s cervical cancer screening behavior. The present study focused on socio-economic variables that affect women’s performance of the Papanicolaou test, comparing two distinct Brazilian populations. Methods: We collected data regarding performance of the Papanicolaou test and socio-economic variables from 559 women in Mato Grosso do Sul (MS), in the Central East region, and 338 women in Paraíba (PB), in the Northeast region of Brazil. Nominal logistic regression modeling was performed to identify independent variables for both groups of data. Results: Of the women interviewed from MS and PB, 116 out of 599 (19.37%) and 94 out of 338 (27.81%), respectively, had not performed the Papanicolaou test within the last three years (p = 0.025). Low educational level characterized 570 (95.16%) and 203 (60.06%) of women from MS and PB, respectively (p = 0.000). Women in PB who had a low educational level and were unemployed had a 2.96-fold (OR = 0.338; 95% CI: 0.121 - 0.939) and 2.40-fold (OR = 0.416; 95% CI: 0.199 - 0.869) lower chance, respectively, to have performed the Papanicolaou test ≥ three times, or once within the last three years (p = 0.029; p = 0.014). The chance of women in MS who did not live in a stable relationship to have performed the test ≥ three times was 1.79-fold (OR = 0.560; 95% CI: 0.348 – 0.901) lower compared to women who reported a stable relationship (p = 0.039). Conclusions: High educational level, employment, and having a stable interpersonal relationship positively associated with performance of the Papanicolaou test among women in PB and MS. Despite having predominantly a low educational level, women in MS performed the Papanicolaou test more frequently than those in PB.
