This study determined the prevalence of syphilis among pregnant women undergoing prenatal care in a neighborhood on the outskirts of the city of Bel\u00e9m, Brazilian Amazon. Methods: This cross-sectional study used data from clinical records of 611 pregnant women who underwent prenatal care at a public health unit in 2019 and 2020. The reagent result for VDRL was used as an indicator of syphilis. Odds Ratio and chi-square tests were used to evaluate the association of information from pregnant women with syphilis. Results: The overall prevalence of syphilis was 5.2 % (32\/611; 95 % CI: 3.5\u20137.0 %). Age under 23 years was identified as a risk factor for syphilis. Conclusions: The prevalence of syphilis among pregnant women in the outskirts of Bel\u00e9m is high, especially among younger women. There is an urgent need to intensify innovative sexual and reproductive health education initiatives and emphasize the importance of consistent practice of preventive measures against syphilis and other STIs in the Amazon region, especially in the young population.<\/jats:p>","DOI":"10.3390\/pathogens13080686","type":"journal-article","created":{"date-parts":[[2024,8,14]],"date-time":"2024-08-14T05:23:27Z","timestamp":1723613007000},"page":"686","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["High
