In this cross-sectional study, we evaluated the impact of STI\/HIV testing campaigns on university campuses from 2013 to 2017. The participants took part in rapid testing for HIV, syphilis, hepatitis B and C, and counseling sessions. A total of 2691 people participated in the campaigns. Of these, 79.4% were single, and 50.3% were women. The median age was 24\u00a0years old, and 77.9% of participants had \u226512\u00a0years of formal education. Most reported having unprotected sex in the last year (87.4%). The positivity rates for HIV, syphilis, hepatitis B virus, and hepatitis C virus were 0.56%, 1.20%, 0.19%, and 0.11%, respectively. The characteristics associated with HIV infection were being men who have sex with men (MSM) (aOR = 12.06; 95% CI = 3.83\u201337.99) and having &lt;12\u00a0years of schooling (aOR = 3.28; 95% CI = 1.03\u201310.38). Factors associated with syphilis seropositivity were older age (aOR = 1.06; 95% CI = 1.03\u20131.09), multiple partners (aOR = 2.44; 95% CI = 1.08\u20135.50), and being MSM (aOR = 5.40; 95% CI = 2.49\u201311.72). Positivity for hepatitis B tended to decrease with the years of testing ( p = 0.023) and for hepatitis C to increase with age ( p = 0.035). Our study observed a high vulnerability to HIV and syphilis infection in a university community, which needs an early prevention strategy, including regular testing, continuing sexual education, easy access to condoms, and pre- and postexposure HIV prophylaxis.<\/jats:p>","DOI":"10.1177\/0956462421997251","type":"journal-article","created":{"date-parts":[[2021,3,26]],"date-time":"2021-03-26T13:39:04Z","timestamp":1616765944000},"page":"821-829","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":4,"title":["Factors associated with sexually transmitted infection\/HIV diagnosis among a predominantly university population in Brazil"],"prefix":"10.1177","volume":"32","author":[{"given":"Isabella GO","family":"Bomfim","sequence":"first","affiliation":[{"name":"Nursing Department, Universidade Federal de S\u00e3o Carlos Center of Biological Sciences and Health, S\u00e3o Carlos, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0366-0250","authenticated-orcid":false,"given":"Sigrid DS","family":"dos Santos","sequence":"additional","affiliation":[{"name":"Department of Medicine, Universidade Federal de S\u00e3o Carlos Center of Biological Sciences and Health, S\u00e3o Carlos, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"C\u00edntia M","family":"Ruggiero","sequence":"additional","affiliation":[{"name":"S\u00e3o Carlos Chronic Infection Care Center, S\u00e3o Carlos, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Anamaria A","family":"Napole\u00e3o","sequence":"additional","affiliation":[{"name":"Nursing Department, Universidade Federal de S\u00e3o Carlos Center of Biological Sciences and Health, S\u00e3o Carlos, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"name":"SANCAHIV","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2021,3,26]]},"reference":[{"key":"bibr1-0956462421997251","doi-asserted-by":"publisher","DOI":"10.1016\/j.epidem.2019.02.002"},{"key":"bibr2-0956462421997251","doi-asserted-by":"publisher","DOI":"10.1590\/1980-549720190001.supl.1"},{"key":"bibr3-0956462421997251","doi-asserted-by":"publisher","DOI":"10.1097\/MD.0000000000010573"},{"key":"bibr4-0956462421997251","unstructured":"UNAIDS.
