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.

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.

This is a cross-sectional study based on an open web survey with the primary objective to assess associations between the use of apps for seeking sex partners and vulnerabilities related to human immunodeficiency virus (HIV) acquisition among men who have sex with men (MSM) in Brazil. Participants were recruited to the study through ads posted in social media such as Twitter, Facebook, and WhatsApp. Consenting respondents completed a questionnaire on demographics, history of sexually transmitted infections (STIs), and risk behaviors and perceptions, including calculation of the Risk Behavior Score for HIV infection proposed by Rocha et al. Among the 859 participants, 714 (83.1%) reported they used apps for seeking sex partners. Use of apps for seeking sex partners was associated with high-risk behavior for HIV infection, self-reported syphilis, self-perception of HIV risk, and use of marijuana. The use of apps for seeking sex partners has rapidly become the norm for MSM in Brazil. The associations with STIs and risk behaviors should be seen as an opening to improve public health, presenting opportunities to promote knowledge, safer sex practices, and referral to HIV/STI screening and prevention interventions.

Men who have sex with men (MSM) are disproportionally affected by the HIV epidemic globally. In Chile, HIV prevalence among MSM is estimated at 20%, and condomless anal intercourse is the predominant mode of HIV transmission. This cross-sectional study aimed to estimate a broad array of characteristics in a sample of Chilean MSM including condomless anal intercourse (CLAI), as well as to explore possible associations between these characteristics and CLAI. MSM were recruited through respondent-driven sampling between June and October of 2016. A final sample size of 246 MSM was analyzed using CLAI as the outcome and sociodemographic, clinical and sexual risk behavior characteristics as exposure variables. Results show that close to half of the participants reported CLAI with casual sex partners during the last six months, and this outcome had an increased risk associated with use of drugs prior to sex and having had >5 sexual partners

In recent years, there has been a significant increase in the use of gay mobile phone applications (gay apps) and HIV prevalence among men who have sex with men (MSM) in China. The aim of this study was to investigate whether there was a relationship between the use of gay apps and HIV infection and provide a targeted intervention to MSM. A cross-sectional study was conducted. Chinese MSM who were over 18 years old and had self-reported homosexual intercourse in the past six months were interviewed in 2016. Proportions were used for categorical variables and determinants of HIV infection were assessed using univariate and multivariate regression. Of the 403 participants, nearly 66.0% reported having used gay apps to seek sexual partners in the past six months. A higher proportion of the gay app users were younger than 19 years old, single, had high school education, were earning less than 115 GBP income per month, and identified themselves as homosexual. Compared to app non-users, a greater proportion of app users reported a higher frequency of male–male sexual contact (≥1 time/week: 57.5% versus 39.4%, p < 0.01), multiple male sex partners (34.2% versus 11.7%, p < 0.001), and unprotected sex with men (51.5% versus 36.5%, p < 0.01) in the past six months. The prevalence of HIV among app users was 7.9%. HIV infection was significantly associated with being an app user (adjusted odds ratio = 5.2, 95% CI = 1.1–24.3). It is suggested that the use of gay apps, especially Blued, is popular among Chinese MSM and is associated with high-risk sexual behaviors and HIV infection. Therefore, there is an urgent need to promote HIV testing and HIV prevention through gay apps to decrease the risk of HIV infection among Chinese MSM.

Introduction: Men who have sex with men (MSM) are one of the key populations driving HIV/AIDS epidemic globally. To date, MSM is the only population in Ukraine where the prevalence and incidence of HIV is increasing. As HIV-positive MSM might feel uncomfortable to report homosexual intercourses as a possible mode of transmission (MoT) of HIV, they prefer being registered as patients with heterosexual or non-defined MoT. This study aimed to calculate the proportion of misclassified MoT among HIV-positive MSM registered in Lviv oblast, Ukraine, during 2014-2018. Methodology: Cross-sectional study with 127 HIV-positive MSM patients from Lviv region for the period of 2014-2018. Results: Out of 127 HIV-positive MSM included in the study, 110 (86.6%) were from urban areas. In addition, 52 patients (40.9%) were diagnosed with stage 1 HIV, 16 (12.6%) – stage 2, 19 (15%) – stage 3, and 36 (28.3%) – stage 4. CD4 count < 200 cells/μL was found in 35 (27.6%) patients. Mean time from registration to antiretroviral therapy initiation was 80 days. During the first visit to medical doctor out of those 48 patients who had previously reported “other modes” of HIV transmission, 33 patients (68.7%) disclosed homosexual MoT of HIV. The remaining 15 (31.3%) patients disclosed their homosexual MoT of HIV later – during their regular follow-up visits to the doctor. Conclusion: Special measures are needed to improve the reporting of homosexual MoT which can potentially strengthen the HIV care among MSM.

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.

Hiv Aids

A high prevalence of HIV infection is present among men who have sex with men (MSM) in China, but many people living with HIV or AIDS (PLWHs) are unaware of their HIV infection status. Provider-initiated HIV testing and counseling (PITC) is a streamlined model that can significantly enhance HIV detection and detect infections earlier. However, PITC has not yet been widely applied, and no studies have been conducted on MSM’s attitudes towards PITC in China. In this study, a total of 438 MSM were recruited in Shenyang city. A multivariate logistic regression model showed that certain conditions made MSM more accepting of PITC: those who had attended VCT (voluntary counseling and testing) more than three times (odds ratio [OR]: 2.95, 95% CI: 1.36–6.37), those who considered PITC beneficial for family and friends (OR: 1.91, 95% CI: 1.25–2.92), those who obtained HIV/AIDS knowledge from brochures (OR: 2.52, 95% CI: 1.64–3.87), those who obtained HIV/AIDS knowledge from the Internet (OR: 1.66, 95% CI: 1.07–2.58), and those who were highly aware of their own risk of being infected with HIV (OR: 2.84, 95% CI: 1.37–5.91). To improve acceptance of PITC among MSM in China, stronger efforts are needed to lower the psychosocial barriers to receiving PITC, to promote HIV/AIDS awareness, and to encourage the extension of HIV testing.
