Sex With Men

HIV prevalence is still rapidly increasing among Chinese men who have sex with men (MSM). The Internet also makes it easier for MSM to have casual partners. This study aims to evaluate the trend of Internet-based sex-seeking behavior of MSM and its impact on HIV prevalence, the distribution of HIV subtype strains, and transmitted drug resistance rates. A serial cross-sectional study was conducted from 2009 to 2014. Of the 1,981 MSM, 50.5% (1,000/1,981) mainly sought homosexual partners through the Internet (Internet-based MSM, IBM). The proportion of IBM among total MSM subjects increased from 43.3% to 61.5% (p<0.001). HIV prevalence of IBM increased from 5.7% to 20.7%, while that of non-Internet-based MSM (NIBM) increased from 7.0% to 14.7%. A relative higher proportion of NIBM were infected with HIV CRF01_AE subtype than IBM (79.5% versus 72.2%, p=0.52). Multivariable analysis found IBM had a significantly higher HIV prevalence than NIBM (13.2% versus 10.5%, aOR = 1.4, 95% CI [1.0–1.9]). Being a migrant non-Shenyang resident MSM (aOR = 1.9, 95% CI [1.3–2.9]) and occasionally/never using condoms with casual homosexual partners (aOR = 1.7, 95% CI [1.1–2.6]) were two distinct risk factors for HIV infection in IBM. More efforts should be targeted towards developing interventions aimed at IBM, particularly migrant MSM and who engage in UAI with casual homosexual partners.

Sex With Men

BACKGROUND Extensive use of geosocial networking (GSN) apps has substantially changed the behaviors and HIV risk among men who have sex with men (MSM). OBJECTIVE We aim to examine the HIV prevalence and risky behaviors among GSN app-using MSM. METHODS We conducted a cross-sectional study among MSM users of Blued (a GSN app) from July 2017 to December 2018. Sociodemographic and behavioural data in the preceding six months were collected through an app-assistant questionnaire, and blood samples were also obtained to test for HIV. HIV prevalence was calculated, and multivariable logistic regression models were constructed to explore the correlates of HIV infection RESULTS A total of 7252 app-using MSM in Beijing were included. The HIV prevalence was 4.7% (95%CI 4.2%-5.2%). In the last six months, nearly half (49.0%) had multiple sexual partners, 3.3% reported having HIV-positive partners, 50.9% were not sure about their current partners’ HIV status. The majority (62.3%) of participants reported consistent condom use, 6.1% had engaged in group sex, and 19.1% had used recreational drug in the past six months. Having college or undergraduate (AOR=0.35, 95%CI 0.16-0.75), or postgraduate (AOR=0.22, 95%CI 0.06-0.78) education, being exclusively insertive in anal intercourse (AOR=0.18, 95%CI 0.07-0.48) were correlated with decreased odds of HIV infection. However, having anal sex (AOR=4.74, 95%CI 1.17-19.19), having 2 to 5 (ORa=1.47 95%CI 1.17-1.86) or six and more (AOR=2.18, 95%CI 1.34-3.55) male sex partners, not consistently using condoms during anal sex (AOR=1.93, 95%CI 1.06-3.52), and being diagnosed with STIs (AOR=3.02, 95%CI 0.95-9.56) in the preceding six months were associated with greater odds of HIV infection. CONCLUSIONS HIV risky behaviors were prevalent among app-using MSM, suggesting more targeted interventions are needed among this population.

ObjectivesTo investigate the relationship between gay app use and HIV testing among men who have sex with men (MSM).DesignSerial cross-sectional study.SettingA newly well-developed city in China.Participants4935 MSM were recruited through offline sampling methods from 2015 to 2017.Primary and secondary outcomesThe primary outcome is the difference in HIV testing between app and non-app users.Results2872 (58.2%) and 2159 (43.7%) participated MSM had been tested for HIV within lifetime and the past year, respectively. Compared with non-app-using MSM, app-using MSM had a significantly higher prevalence of HIV testing within lifetime (adjusted OR (AOR): 1.48, 95% CI 1.27 to 1.72) and the past year (AOR: 1.36, 95% CI 1.18 to 1.57). App-using MSM were more likely to take an HIV test at the Centers for Disease Control and Prevention (AOR: 1.48, 95% CI 1.24 to 1.76) and community-based organisations (AOR: 1.71, 95% CI 1.44 to 2.03), but less often at gay venues (AOR: 0.49, 95% CI 0.37 to 0.63). Meanwhile, app-using MSM were more likely to take self-testing (AOR: 1.61, 95% CI 1.21 to 2.14). Predictors of HIV testing in the past year were: having an education level of college or higher (AOR: 1.29, 95% CI 1.01 to 1.65), being self-identified as a homosexual (AOR: 1.23, 95% CI 1.02 to 1.46), being recruited through clinic-based sampling (AOR: 1.30, 95% CI 1.06 to 1.60), using gay app (AOR: 1.49, 95% CI 1.21 to 1.83), engaging in group sex (AOR: 1.64, 95% CI 1.23 to 2.19), having received HIV-related service (AOR: 5.49, 95% CI 4.57 to 6.60), having a high level of HIV-related knowledge (AOR: 1.33, 95% CI 1.10 to 1.61) and high-risk perception (AOR: 2.95, 95% CI 1.40 to 6.23).ConclusionsGay app use was significantly associated with increased HIV testing among MSM hard to reach by traditional outreach. Therefore, it is imperative to expand HIV testing among non-app-using MSM. Continued efforts, innovative strategies and increased resource are highly needed to realise the first ‘90’ target.
