Methods: An observational, cross-sectional study was carried out in a subnormal agglomerate from the Brazilian Amazon. Data collection was conducted from August 2021 to February 2022, using a structured questionnaire. Whole blood samples were collected to perform a rapid test for HIV and syphilis. People aged 50 and over were included in the study, and the sample consisted of 213 participants. The odds ratio was calculated by multiple logistic regression. Results: A total of 203 participants with a mean age of 63.5 years were considered (95% CI: 62.4; 64.6; standard deviation: 8.1; minimum age: 50 years and maximum age: 94 years). The prevalence of either HIV or syphilis was 16.4% (35\/213; 95% CI: 0.11; 0.21); syphilis was 15.5% (33\/213) and HIV was 1.40% (3\/213). One coinfection (0.46%; 1\/213) was registered. In the final multiple logistic regression, the elderly with an education level of illiterate\/elementary were two times more likely to have a positive rapid test result for HIV or syphilis. Conclusions: Testing for HIV and syphilis identified that STI represented a burden on populations affected by socioeconomic inequality.<\/jats:p>","DOI":"10.3390\/tropicalmed7110332","type":"journal-article","created":{"date-parts":[[2022,10,30]],"date-time":"2022-10-30T10:47:57Z","timestamp":1667126877000},"page":"332","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Prevalence and Vulnerability Factors Associated with HIV and Syphilis in Older People from Subnormal Agglomerate, Brazilian Amazon"],"prefix":"10.3390","volume":"7","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6125-3261","authenticated-orcid":false,"given":"Wanderson Santiago de","family":"Azevedo Junior","sequence":"first","affiliation":[{"name":"Program of Post-Graduation in Nursing, Federal University of Par\u00e1, Bel\u00e9m 66075-110, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eduarda Pastana dos","family":"Santos","sequence":"additional","affiliation":[{"name":"Nursing School, Federal University of Par\u00e1, Bel\u00e9m 66075-110, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"N\u00e1bia Pereira","family":"Pedreira","sequence":"additional","affiliation":[{"name":"Nursing School, Federal University of Par\u00e1, Bel\u00e9m 66075-110, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lucas Bittencourt","family":"Dantas","sequence":"additional","affiliation":[{"name":"Nursing School, Federal University of Par\u00e1, Bel\u00e9m 66075-110, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Val\u00e9ria Gabrielle Caldas","family":"Nascimento","sequence":"additional","affiliation":[{"name":"Program of Post-Graduation in Nursing, Federal University of Par\u00e1, Bel\u00e9m 66075-110, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Geyse Aline Rodrigues","family":"Dias","sequence":"additional","affiliation":[{"name":"Nursing School, Federal University of Par\u00e1, Bel\u00e9m 66075-110, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fabiane de Jesus Dias","family":"Sousa","sequence":"additional","affiliation":[{"name":"Program of Post-Graduation in Nursing, Federal University of Par\u00e1, Bel\u00e9m 66075-110, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"N\u00e1dile Juliane Costa de","family":"Castro","sequence":"additional","affiliation":[{"name":"Program of Post-Graduation in Nursing, Federal University of Par\u00e1, Bel\u00e9m 66075-110, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eli\u00e3 Pinheiro","family":"Botelho","sequence":"additional","affiliation":[{"name":"Program of Post-Graduation in Nursing, Federal University of Par\u00e1, Bel\u00e9m 66075-110, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8206-4950","authenticated-orcid":false,"given":"Glenda Roberta Oliveira Naiff","family":"Ferreira","sequence":"additional","affiliation":[{"name":"Program of Post-Graduation in Nursing, Federal University of Par\u00e1, Bel\u00e9m 66075-110, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,10,28]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"The Lancet Healthy Longevity (2022).
