Our objective is to evaluate the prevalence of syphilis and determine the risk factors of syphilis among HIV-positive MSM.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>A cross-sectional study with convenience sampling was performed among HIV-positive MSM in six cities of Guangdong Province from June 2020 to August 2021. Participants completed a survey including social-demographic characteristics, sexual behaviors and self-reported syphilis, chlamydia, gonorrhea, herpes, human papillomavirus statuses after HIV diagnosis. Multivariate logistic regression was used to determine the factors associated with syphilis and sexually transmitted diseases (STD).<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Among 944 HIV-positive MSM, 141 (14.9, 95% CI: 12.7\u201317.2%) men had syphilis and 220 (23.3, 95% CI: 20.6\u201326.0%) men had STD. Multivariate analysis indicated that MSM who met male sexual partners mainly through traditional meeting places (spa or bath house, sauna, foot or body massage parlor) in the last 6 months [adjusted Odds Ratio (a<jats:italic>OR<\/jats:italic>) = 2.91, 95% CI: 1.09\u20137.79], and who were diagnosed with herps after the HIV diagnosis (a<jats:italic>OR<\/jats:italic> = 3.79, 95% CI: 1.16\u201312.39) were more likely to have syphilis. In addition, MSM who met male sexual partners mainly through traditional meeting places in the last 6 month (a<jats:italic>OR<\/jats:italic> = 2.55, 95% CI: 1.01\u20136.42), and who had more than one male sexual partner in the last 6 months (a<jats:italic>OR<\/jats:italic> = 1.88, 95% CI: 1.17\u20133.02) were more likely to have STD.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>The prevalence of syphilis and other STDs is relatively high among HIV-positive MSM in southern China. Routine syphilis screening as a part of HIV monitoring among HIV-positive MSM will have important epidemiological significance for the management of infected patients, and can help reduce the spread of syphilis.<\/jats:p><\/jats:sec>","DOI":"10.3389\/fpubh.2022.1025221","type":"journal-article","created":{"date-parts":[[2022,11,9]],"date-time":"2022-11-09T06:06:32Z","timestamp":1667973992000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":5,"title":["Prevalence of syphilis and risk factors among HIV-positive men who have sex with men in Guangdong province"],"prefix":"10.3389","volume":"10","author":[{"given":"Peizhen","family":"Zhao","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ziying","family":"Yang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ye","family":"Zhang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jinmei","family":"Chen","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xuezhen","family":"Fu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Weiming","family":"Tang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jiyuan","family":"Zhou","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1965","published-online":{"date-parts":[[2022,11,9]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"1000","DOI":"10.1186\/s12879-019-4559-1","article-title":"The prevalence of HIV among MSM in China: a large-scale systematic analysis","volume":"19","author":"Dong","year":"2019","journal-title":"BMC Infect Dis"},{"key":"B2","doi-asserted-by":"publisher","first-page":"1507","DOI":"10.3390\/ijerph16091507","article-title":"Prevalence of active syphilis infection and risk factors among HIV-positive MSM in Zhejiang, China in 2015: a cross-sectional study","volume":"16","author":"Chen","year":"2019","journal-title":"Int J Environ Res Public Health"},{"key":"B3","first-page":"501","article-title":"Latest AIDS epidemic in global and China","volume":"33","author":"Zhengran","year":"2020","journal-title":"Infect Dis Info"},{"key":"B4","doi-asserted-by":"publisher","first-page":"266","DOI":"10.1016\/j.ram.2020.01.002","article-title":"Syphilis seroprevalence among HIV-infected males in Istanbul, Turkey","volume":"52","author":"K\u00f6ksal","year":"2020","journal-title":"Revista Argentina de Microbiolog"},{"key":"B5","doi-asserted-by":"publisher","first-page":"410","DOI":"10.1177\/0956462413512804","article-title":"Prevalence of syphilis infection and associations with sexual risk behaviours among HIV-positive men who have sex with men in Shanghai, China","volume":"25","author":"He","year":"2014","journal-title":"Int J Std AIDS"},{"key":"B6","doi-asserted-by":"publisher","DOI":"10.1258\/ijsa.2012.011411","article-title":"Seroprevalence of hepatitis C, hepatitis B virus and syphilis in HIV-1 infected patients in Shandong, China","author":"Zhao","year":"2012","journal-title":"Int J Std AIDS."},{"key":"B7","doi-asserted-by":"publisher","first-page":"1157","DOI":"10.1080\/09540121.2019.1612006","article-title":"Risk factors of syphilis co-infection among HIV-infected men who have sex with men in Tel-Aviv, Israel","volume":"31","author":"Polansky","year":"2019","journal-title":"AIDS Care"},{"key":"B8","doi-asserted-by":"publisher","first-page":"321","DOI":"10.1080\/14787210.2018.1446828","article-title":"Syphilis incidence in men who have sex with men with human immunodeficiency virus comorbidity and the importance of integrating sexually transmitted infection prevention into HIV care","volume":"16","author":"Refugio","year":"2018","journal-title":"Expert Rev Anti Infect Ther"},{"key":"B9","unstructured":"HIV Prevention Through Early Detection and Treatment of Other Sexually Transmitted Diseases -
