Abstract Background Condomless anal intercourse (CAI) appears to be increasing among men who have sex with men (MSM) globally, and is reported to be as high as 70% in recent studies in Peru. To improve understanding of the evolving context of CAI among MSM in Peru, we studied associations between partner type, substance use, and condomless anal intercourse (CAI) in locations where MSM commonly report having sexual encounters. Methods In a 2017 cross-sectional study of rectal STI screening and HIV prevention, a convenience sample of MSM recruited from community venues in Lima completed a survey of demographic characteristics and sexual risk behavior with their three most recent partners. Generalized estimating equations estimated correlations of CAI with location of last sexual contact, participant substance use prior to sex, and negotiation of condom use before or during sex. The network data integration application, Cytoscape, mapped intersections of partner type, sexual orientation, substance use, and CAI by four types of locations where sex occurred: 1) Home, 2) Hotel, 3) Sauna or Internet Cabin, and 4) Public Spaces. Results Of 447 MSM (median age 27 years), 76.9% reported CAI with ≥1 of their last three partners. Participants reported sex with casual partners most commonly in homes (64.6%) and hotels (60.4%), and with anonymous partners most often in saunas/Internet cabins (57.5%) and public spaces (52.6%). CAI was less commonly reported in hotels (aPR, 95% CI: 0.85, 0.75–0.97) compared to homes. Participants who used marijuana before sex at home were more likely to report CAI than MSM who did not use marijuana (1.36, 1.01–1.92). Partner alcohol use before sex was associated with CAI in saunas/Internet cabins (3.17, 1.45–6.91) and public spaces (2.65, 1.41–4.98). In the sexual network maps, almost all MSM who used drugs prior to their sexual encounters used drugs with more than one of their last three partners. Conclusions CAI was common and associated with different risk factors, like partner type and substance use, based on location where sex occurred. Novel combination HIV, STI, and substance use prevention interventions must consider how the social environments of MSM influence condom use and other sexual risk behaviors.

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.

Abstract Background Rectal douching (RD) is widely practiced by men who have sex with men (MSM), and is associated with increased risk of HIV infection. However, the mechanism of how RD increases the risk of HIV infection is not well understood, and there is limited data on RD behavior in MSM practicing anal sex in China. We examine the purpose of RD, its timing in relation to anal sex, the types of RD products used, and risky sexual behaviors among MSM reporting anal sex. Methods Between August 2017 and December 2018, a cross-sectional study was conducted among adult MSM in Shenyang, China. Data were collected on demographics, sexual behaviors, and RD for the most recent sexual intercourse by means of interviewer-administered face-to-face questionnaires. Blood samples were collected to test for antibodies to HIV and syphilis. Multivariable logistic regression models were used to assess the risk factors associated with HIV infection. Results A total of 515 eligible MSM participated in this survey (median age: 31 years). During the most recent anal intercourse, 28.3% (146/515) had condomless receptive anal intercourse (CRAI), 21.4% (110/515) practiced serosorting, and more than half (61.6%, 317/515) reported RD before or after anal sex. Of those practicing RD, 96.8% (307/317) conducted RD before sex, while 62.5% (198/317) conducted RD after sex. The douching devices used were primarily shower hoses (85.3%, 262/307), and relatively few MSM used commercial RD products (8.1%, 25/307) before sex. The prevalence of HIV-1 and syphilis was 11.7% and 13.2%, respectively. HIV infection was positively associated with RD, practicing RD before sex, the interaction between RD and CRAI using a shower hose for RD and other risk factors, practicing RD after sex, CRAI, using nitrite inhalants, main sexual role with males as bottom and syphilis infection. Conclusions RD is popular among Chinese MSM. Improper noncommercial RD tools use (such as shower hose), the interaction effect between RD and CRAI associated with HIV infection. Public health workers and the MSM community should publicize scientific knowledge and prevention approaches relating to RD and HIV transmission to MSM. We recommend that further studies should be conducted to understand the detailed mechanism between RD and increased HIV prevalence.

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.
