Summary
Syphilis prevalence in Brazilian parturient women was 0.89%, linked to fewer prenatal visits and social inequalities. Despite reductions, the disease persists, particularly in certain regions and among specific racial/educational groups.
Area of Science:
- Public Health
- Epidemiology
- Infectious Diseases
Background:
- Syphilis remains a significant public health concern globally, particularly among pregnant populations.
- Understanding the prevalence and associated factors of syphilis in parturient women is crucial for targeted interventions.
Purpose of the Study:
- To estimate the prevalence of syphilis among parturient women in Brazil.
- To investigate sociodemographic and healthcare-related factors associated with syphilis in this population.
Main Methods:
- A nationwide, cross-sectional, population-based study involving 36,713 parturient women aged 15-49 years.
- Syphilis screening using rapid treponemal tests, confirmed by Venereal Disease Research Laboratory (VDRL) and treponemal tests.
- Data collection via questionnaires and review of prenatal records; logistic regression analysis for associations.
Main Results:
- The overall prevalence of syphilis was 0.89%, with regional variations (e.g., 1.20% in Mid-West, 0.48% in South).
- Syphilis was associated with absence, fewer, or late initiation of prenatal consultations.
- Higher risk observed in women of yellow, black, and brown race/skin color and those with less schooling.
Conclusions:
- A reduction in syphilis prevalence in Brazil was noted, but the disease is still linked to social and regional disparities.
- Persistent syphilis highlights the need for improved access to and engagement with prenatal care, especially for vulnerable populations.
