In total, 246 participants were included in the analyses (median age: 18.8; IQR: 18.2\u201319.4 years). The overall oropharyngeal, anal, and urethral prevalence rates of NG were 17.9%, 9.4%, 7.6%, and 1.9%, respectively. For CT, the overall, oropharyngeal, anal, and urethral prevalence rates were 5.9%, 1.2%, 2.4%, and 1.9%, respectively. A low level of education, clinical suspicion of STI (and coinfection with <jats:italic>Mycoplasma hominis<\/jats:italic> were associated with NG infection. The prevalence of NG and CT, especially extragenital infections, was high in AMSM and ATGW. These findings highlight the need for testing samples from multiple anatomical sites among adolescents at a higher risk of STI acquisition, implementation of school-based strategies, provision of sexual health education, and reduction in barriers to care.<\/jats:p>","DOI":"10.1017\/s095026882300170x","type":"journal-article","created":{"date-parts":[[2023,10,23]],"date-time":"2023-10-23T09:30:02Z","timestamp":1698053402000},"update-policy":"https:\/\/doi.org\/10.1017\/policypage","source":"Crossref","is-referenced-by-count":5,"title":["Prevalence of <i>Neisseria gonorrhoeae<\/i> and <i>Chlamydia trachomatis<\/i> infections among adolescent men who have sex with men and transgender women in Salvador, Northeast Brazil"],"prefix":"10.1017","volume":"151","author":[{"given":"Caio Marcellus","family":"Oliveira","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8276-8149","authenticated-orcid":false,"given":"Lucas Miranda","family":"Marques","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Danielle Souto de","family":"Medeiros","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Valdiele de Jesus","family":"Salgado","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fabiane","family":"Soares","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Laio","family":"Magno","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"In\u00eas","family":"Dourado","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"\u00c1ghata Morgana Bertoti","family":"da Silva","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Henrique In\u00e1cio Lima de","family":"Brito","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tiana Baqueiro","family":"Figueiredo","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Guilherme Barreto","family":"Campos","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"56","published-online":{"date-parts":[[2023,10,23]]},"reference":[{"key":"S095026882300170X_r28","first-page":"1","article-title":"Recommendations for the laboratory-based detection of Chlamydia trachomatis and Neisseria gonorrhoeae--2014","volume":"63","author":"Papp","year":"2014","journal-title":"Morbidity and Mortality Weekly Report.
