The weighted syphilis seroprevalence in the study population was 29.2% (95% CI 23.9, 35.1). A bivariate probit multiple regression model was used to estimate the outcomes. Characteristics that were positively associated with syphilis seropositivity included being age 19\u201320, 21\u201324, and at least age 25 compared to the reference group (age 16\u201318 years old) (0.72 [95% CI 0.18, 1.25], 1.40 [95% CI 0.68, 2.13], and 1.34 [95% CI 0.75,1.94], respectively), using social media to meet sexual partners (0.33 [95% CI 0.05, 0.61]), using condoms more often (0.39 [95% CI 0.02, 0.76]), and a history of criminal justice involvement (0.25 [95% CI 0.06, 0.44]). Our study results suggest that among YBMSM in Chicago, interventions promoting condom use may be less effective for syphilis prevention compared to HIV prevention in this population. The contribution of nonpenetrative sex to syphilis prevalence requires additional research as does how best to implement routine syphilis screening and treatment for YBMSM in the context of ongoing syphilis transmission.<\/jats:p>","DOI":"10.1177\/0956462418816449","type":"journal-article","created":{"date-parts":[[2019,1,9]],"date-time":"2019-01-09T08:18:05Z","timestamp":1547021885000},"page":"396-403","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":2,"title":["Behavioral characteristics and their association with syphilis seroprevalence among a cohort of young Black men who have sex with men"],"prefix":"10.1177","volume":"30","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6260-2478","authenticated-orcid":false,"given":"Dovie L","family":"Watson","sequence":"first","affiliation":[{"name":"Department of Medicine, University of Pennsylvania, Philadelphia, PA, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chuanhong","family":"Liao","sequence":"additional","affiliation":[{"name":"Department of Public Health Sciences, University of Chicago, Chicago, IL, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jessica","family":"Ridgway","sequence":"additional","affiliation":[{"name":"Department of Medicine, University of Chicago, Chicago, IL, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7870-5639","authenticated-orcid":false,"given":"John A","family":"Schneider","sequence":"additional","affiliation":[{"name":"Department of Public Health Sciences, University of Chicago, Chicago, IL, USA"},{"name":"Department of Medicine, University of Chicago, Chicago, IL, USA"},{"name":"Chicago Center for HIV Elimination, University of Chicago, Chicago, IL, USA"},{"name":"NORC, Chicago, IL, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2019,1,8]]},"reference":[{"key":"bibr1-0956462418816449","unstructured":"Centers for Disease Control and Prevention (CDC). 2016 sexually transmitted diseases surveillance, https:\/\/www.cdc.gov\/std\/stats16\/ (2017, accessed 19 November 2017)."},{"key":"bibr2-0956462418816449","doi-asserted-by":"publisher","DOI":"10.7326\/0003-4819-155-3-201108020-00004"},{"key":"bibr3-0956462418816449","doi-asserted-by":"publisher","DOI":"10.1097\/QAI.0b013e318230e1ca"},{"key":"bibr4-0956462418816449","doi-asserted-by":"publisher","DOI":"10.1097\/OLQ.0000000000000056"},{"key":"bibr5-0956462418816449","doi-asserted-by":"publisher","DOI":"10.1097\/QAD.0000000000001185"},{"key":"bibr6-0956462418816449","doi-asserted-by":"publisher","DOI":"10.1016\/S1473-3099(14)70847-3"},{"key":"bibr7-0956462418816449","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1017\/nws.2016.28","volume":"5","author":"Schneider JA","year":"2017","journal-title":"Network Sci"},{"key":"bibr8-0956462418816449","doi-asserted-by":"publisher","DOI":"10.1097\/QAI.0000000000001379"},{"key":"bibr9-0956462418816449","unstructured":"Chang M, Dragavon J, Hart S, Selle A, Murphy S, Michaels S, et al.
