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.

ObjectivesTo estimate HIV prevalence and associated risk factors among men who have sex with men (MSM) in Dar es Salaam, Tanzania following the implementation of the national comprehensive package of HIV interventions for key population (CHIP).DesignA cross-sectional survey using respondent-driven sampling.SettingDar es Salaam, Tanzania’s largest city.ParticipantsMen who occasionally or regularly have sex with another man, aged 18 years and above and living in Dar es Salaam city at least 6 months preceding the study.Primary outcome measureHIV prevalence was the primary outcome. Independent risk factors for HIV infection were examined using weighted logistics regression modelling.ResultsA total of 777 MSM with a mean age of 26 years took part in the study. The weighted HIV prevalence was 8.3% (95% CI: 6.3%–10.9%) as compared with 22.3% (95% CI: 18.7%–26.4%) observed in a similar survey in 2014. Half of the participants had had sex with more than two partners in the month preceding the survey. Among those who had engaged in transactional sex, 80% had used a condom during last anal sex with a paying partner. Participants aged 25 and above had four times higher odds of being infected than those aged 15–19 years. HIV infection was associated with multiple sexual partnerships (adjusted OR/AOR, 3.0; 95% CI: 1.8–12.0), not having used condom during last sex with non-paying partner (AOR, 4.1; 95% CI: 1.4–7.8) and ever having engaged in group sex (AOR, 3.4; 95% CI: 1.7–3.6).ConclusionHIV prevalence among MSM in Dar es Salaam has decreased by more than a half over the past 5 years, coinciding with implementation of the CHIP. It is nonetheless two times as high as that of men in the general population. To achieve the 2030 goal, behavioural change interventions and roll out of new intervention measures such as pre-exposure prophylaxis are urgently needed.

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.

BACKGROUND Finding casual sex partners on the Internet has been considered as a new challenge for HIV transmission among men who have sex with men (MSM). OBJECTIVE To identify the characteristics and risk factors of men who have sex with men (MSM) finding casual sex partners on the Internet for a new challenge regarding HIV transmission. METHODS This was a cross-sectional study. Participants were enrolled by four community-based organizations (CBOs) through bathroom, bar and gay applications. Online survey was conducted to collected information on finding casual sex partners, HIV knowledge, HIV-risk behaviors. RESULTS Among 767 participants, 310(40.4%) reported ever finding causal sex partners on the Internet. Factors associated with finding casual sex partners online in multivariate logistic regression analysis included watching pornographic videos on the Internet more than once per week (adjusted odds ratio (aOR) = 1.881, 95% CI: 1.201–2.948), discussing “hooking-up online” with friends (aOR = 4.018, 95%CI: 2.910–5.548), and perceiving that the likelihood of HIV infection in online casual sex partners was “very high” (aOR = 2.034, 95%CI: 1.441–2.873) or “high/medium/low” (aOR = 2.548, 95% CI: 1.524–4.259). Among the 310 participants who reported finding casual sex partners online, 30.2% reported having unprotected sex with casual sex partners met online in the past 6 months. In multivariate logistic regression analysis, knowing the HIV infection status of online casual sex partners was significantly associated with a decreased risk of inconsistent condom use (aOR = 0.327, 95% CI: 0.167–0.642). CONCLUSIONS Internet-based casual sexual behavior is becoming more prevalent, and the rate of unprotected sex among MSM in Zhejiang Province is high. Future HIV prevention approaches should emphasize the importance for MSM of proactively determining the HIV infection status of potential online casual sex partners.

Background: This paper presents the prevalence of human immuno deficiency virus (HIV) infection among men who have sex with men (MSM) attending integrated counselling and testing Centres (ICTC) in selected districts of Karnataka.Methods: A cross sectional study was done at ICTCs. Men and transgenders coming with referral slips from targeted intervention (TI), non-government organizations (NGOs) were considered as MSMs. The basic demographic data, HIV test result and details of post- test counselling were collected in specific format. Data from 13 districts was obtained from April 2009 to March 2010 and comparing the prevalence of HIV among MSM in HIV sentinel surveillance (HSS).Results: Out of 8,276 MSMs in 13 districts, 2808 (33.9%) visited ICTCs with TI NGOs referral slips and were tested for HIV once in a year. The overall prevalence of HIV was 8.6%. Prevalence was highest (17.3%) among men in the age group of 41 to 45 years, illiterates (11.5%), unemployed (11.2%) and divorced and separated (13.3%) and widowed (13.6%) MSMs. Among those tested, 97.7% of MSM underwent post-test counselling and collected their report. The highest HIV prevalence was among MSMs from Mysore district (20.1%), followed by Udupi (19.9%) and Bagalkot (10.6%). Rest of all the other districts had less than 10% of HIV prevalence.Conclusions: The uptake of HIV testing among the MSM with referral slips was low in Karnataka. The prevalence level differs in various districts. There is need for more focused and effective counselling by peer educators for correct and consistent condom usage among illiterate, widowed and unemployed MSMs.

Sex With Men

In Taiwan, men who have sex with men (MSM) are at disproportionate risk of HIV infection. We examined awareness and acceptability of future HIV vaccines. From July to August 2014, we conducted a cross-sectional survey with MSM recruited through community-based organizations (CBOs) in 2 cities. Among 200 participants (mean age, 27.6 years), half reported multiple partners and one-third condomless anal sex (past 3 months); 12% were HIV-positive. Traditional Chinese medicine (TCM) use was reported by 42.7%. Over two-thirds (69.0%) were aware of HIV vaccine research, but less than half (43.8%) would accept an HIV vaccine if available. In multivariable analysis, higher educational attainment, >5 sex partners, and TCM use were positively associated with HIV vaccine awareness. Culturally informed HIV vaccine preparedness in Taiwan may be supported by a complementary approach to TCM and HIV prevention technologies, tailoring information for MSM with lower education and targeting those at high risk through gay-identified CBOs.

Objective. To analyze sociodemographic and behavioral factors associated with vulnerability to HIV according to sexual orientation. Method. This is a cross-sectional study conducted using data on 3,818 people in the city of Imperatriz, Brazil, during 2015 and 2016. The survey’s questionnaires addressed sociodemographic and behavioral variables. For the data analysis, association (chi-square test) and strength of association (odds ratio) were observed. A significance level of p<0.05 and adjustment for age and gender were taken into consideration. Results. A substantial portion of the sample stated they were heterosexual (88.8%). These individuals demonstrated a lower chance of HIV infection (p<0.001), sexually transmitted infections (p<0.001), alcohol use (p<0.001) and condom use (p<0.001), compared to men who have sex with men and/or bisexuals. In this group, after adjusting for confounding variables, the factors associated with HIV infection were being male (p<0.001), unmarried (p<0.001), having completed higher education (p<0.001) and boasting multiple sexual partners (p<0.001). Conclusion. Behavioral and sociodemographic factors of vulnerability to HIV are predominant among men who have sex with men and/or are bisexual.

Gay dating applications (apps) are popular among men who have sex with men (MSM) in China. This study examined the relationship between gay dating app use frequency and condomless anal intercourse (CAI) in a sample of MSM in Beijing. In October 2017, a web-based, cross-sectional survey was conducted among MSM from Beijing, China. Demographics, frequency of app use, and sexual behaviors were collected and analyzed. Multivariable logistic regression and restricted cubic splines were used to evaluate the association between app use frequency and CAI. Of the 9280 participants, the proportion of CAI within one month prior to the survey was 43.3%, and 43.7% logged onto the app ≥11 times per week. In adjusted logistic regression analysis, logging onto the app 6–10 times per week and ≥11 times per week were inversely associated with CAI (adjusted odds ratio [AOR] =0.88 [95%CI, 0.78–0.99]; AOR = 0.88 [95%CI, 0.82–0.97], respectively). Among those 40 years of age or older, logging onto the app ≥11 times per week was associated with lower rates of CAI (AOR = 0.57 [95%CI, 0.40–0.81]). Results indicate that frequent app use was associated with lower odds of CAI among MSM in Beijing, China. Innovative interventions, which take advantage of this popular media platform, should be developed as such apps have been found to reduce the odds of CAI in Beijing.
