This study determined the prevalence and factors associated with syphilis in people living with HIV\/AIDS in the city of Bel\u00e9m, northern Brazil. A cross-sectional study was conducted from June to November 2018. A total of 500 people living with HIV\/AIDS attended at a specialized unit of the public health network of the State of Par\u00e1 were studied. Questionnaires were used to collect socio-demographic data and potential risk factors for syphilis. Blood samples were collected from all subjects and screened for syphilis using VDRL, and the seropositive were confirmed using FTA-abs. Logistic regressions were used to identify the factors associated with syphilis. Most subjects were male (56.8%), had more than 40 years (54.0%), single (63.0%), had finished high school (54.2%), had monthly income \u22641 minimum wage (72.4%), and had been born to the city of Bel\u00e9m (59.8%). Prevalence of syphilis was 6.4%. Eight characteristics\/behaviors associated with syphilis: male, young adults, single, studied at least high school, monthly income &amp;gt;1 minimum wage, homosexual\/bisexual, does not use or sporadically use condoms during sexual intercourse, and have had more than one sexual partner in the last three months. The prevalence of syphilis in people living with HIV\/AIDS in Bel\u00e9m is low when compared to other Brazilian states. However, there is a need for public policies and actions to monitor, control and prevent these two sexually transmitted infections.<\/jats:p>","DOI":"10.3389\/fpubh.2021.646663","type":"journal-article","created":{"date-parts":[[2021,8,9]],"date-time":"2021-08-09T06:08:01Z","timestamp":1628489281000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":16,"title":["Prevalence and Factors Associated With Syphilis in People Living With HIV\/AIDS in the State of Par\u00e1, Northern Brazil"],"prefix":"10.3389","volume":"9","author":[{"given":"Pedro Le\u00e3o Fontes","family":"Neto","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ricardo Roberto de Souza","family":"Fonseca","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maria Eduarda de Sousa","family":"Avelino","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Elizandro Monteiro","family":"Vilhena","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maria dos Anjos de Abreu Pina","family":"Barbosa","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Carmen Andrea Freitas","family":"Lopes","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Samara Tatielle Monteiro","family":"Gomes","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bianca Jorge","family":"Sequeira","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rog\u00e9rio Valois","family":"Laurentino","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Felipe Bonfim","family":"Freitas","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Aldemir Branco","family":"Oliveira-Filho","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Luiz Fernando Almeida","family":"Machado","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2021,8,9]]},"reference":[{"key":"B1","unstructured":""},{"key":"B2","unstructured":"Boletim Epidemiol\u00f3gico de HIV e Aids, 2020."},{"key":"B3","doi-asserted-by":"publisher","first-page":"821","DOI":"10.1089\/aid.2018.0036","article-title":"High Seroprevalence of Syphilis Among HIV-Infected Patients and Associated Predictors","volume":"34","author":"da Silva","year":"2018","journal-title":"AIDS Res Hum Retroviruses."},{"key":"B4","doi-asserted-by":"publisher","first-page":"e0170773","DOI":"10.1371\/journal.pone.0170773","article-title":"Costing of National STI Program implementation for the global STI control strategy for the health sector, 2016-2021","volume":"12","author":"Korenromp","year":"2017","journal-title":"PLoS ONE."},{"key":"B5","doi-asserted-by":"publisher","first-page":"24","DOI":"10.1007\/s40471-018-0138-z","article-title":"An update on the global epidemiology of syphilis","volume":"5","author":"Kojima","year":"2018","journal-title":"Curr Epidemiol Rep."},{"key":"B6","unstructured":"Boletim Epidemiol\u00f3gico de S\u00edfilis 2020"},{"key":"B7","doi-asserted-by":"publisher","first-page":"1750","DOI":"10.1093\/cid\/ciy348","article-title":"HIV Outpatient Study Investigators.
