Objective: to identify the rate of reactive treponemal and non-treponemal tests in pregnant women during childbirth and to analyze the factors associated with this seroreactivity. Method: this is a cross-sectional, quantitative study with secondary sources of sociodemographic and clinical data on 2,626 pregnant women treated at a public maternity hospital in the interior of São Paulo, in 2020. For statistical analysis, Fisher’s exact test, Mann-Whitney test and the logistic regression model were used. A difference of p < 0.05 was considered statistically significant. Results: the rate of seropositivity for syphilis among pregnant women in this series was 2.74%. Among the groups with positive and non-reactive tests, marital status, occupation, place of residence and use of licit drugs indicated significant differences, but, in the final model, only unmarried marital status was associated with reactive tests (Odds Ratio: 0.169; Confidence Interval: 0.04–0.72; and p: 0.016). Conclusion: in this study, unmarried marital status was the only independent factor associated with seroreactivity for syphilis. Therefore, it is necessary to create strategies aimed at women in this condition, potentially reducing the rate of congenital syphilis.

RESUMO Objetivo: identificar a taxa de testes treponêmicos e não treponêmicos reagentes em gestantes no período do parto e analisar os fatores associados a essa sororreatividade. Método: estudo transversal, quantitativo, com fontes secundárias de dados sociodemográficos e clínicos de 2.626 gestantes atendidas em uma maternidade pública do interior paulista, em 2020. Para a análise estatística, foram utilizados os Testes Exato de Fisher, de Mann-Whitney e o modelo de regressão logística. Considerou-se diferença com significância estatística valores de p < 0,05. Resultados: a taxa de soropositividade para sífilis entre gestantes nesta casuística foi de 2,74%. Entre os grupos com testes reagentes e não reagentes à situação maritária, ocupação, local da residência e uso de drogas lícitas indicaram diferenças significantes, mas, no modelo final, apenas a situação marital não casada apresentou associação com os testes reagentes (Odds Ratio: 0,169; Intervalo de Confiança: 0,04–0,72; e p: 0,016). Conclusão neste estudo, a situação maritária não casada foi o único fator independente associado à sororreatividade para a sífilis. Por isso, faz-se necessária a criação de estratégias voltadas para mulheres nessa condição, potencialmente reduzindo a taxa de sífilis congênita.

Objective To evaluate the seroprevalence of toxoplasmosis among puerperal women cared for at a tertiary university hospital and the level of understanding of these puerperal women about toxoplasmosis, vertical transmission, and its prophylaxis. Methods For this cross-sectional study, we evaluated 225 patients using presential interviews, prenatal documentation, and electronic medical records. Data were stored using Research Electronic Data Capture (REDCap) software. Prevalence rates were estimated by the presence of reactive IgG antibodies against Toxoplasma gondii. Data analysis was performed using the chi-square test and calculation of the odds ratio (OR). Seroreactivity to T. gondii and exposure variables (age, educational level, and parity) were analyzed using a confidence interval (95%CI) and a significance level of 5% (p < 0.05). Results The seropositivity rate for T. gondii was 40%. There was no association between seroprevalence and age. Primiparity was a protective factor against seropositivity and low education was a risk factor. Conclusion Knowledge of T. gondii infection and its transmission forms was significantly limited, presenting a risk for acute maternal toxoplasmosis and vertical transmission of this protozoan. Increasing the education level regarding the risk of toxoplasmosis during pregnancy could reduce the rates of infection and vertical transmission of this parasite.
