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.

ObjectivesTraditionally, subjects' migration status has usually been defined on the basis of their registered residency status. We attempted to redefine migration based on the duration of residency in their cities of migration and to explore more precisely the impact of migration on HIV infection risk in men who have sex with men (MSM).MethodsA multisite cross-sectional study was conducted during 2012–2013 in seven Chinese cities. Questionnaire surveys were conducted and blood was drawn to test for antibodies to HIV, syphilis and herpes simplex virus-2 (HSV-2). MSM who were unregistered local residents and had resided in their cities of migration for ≤1 or >1 year were defined as migrant MSM, or transitional MSM, respectively.ResultsCompared with transitional MSM and local MSM, migrant MSM had poorer HIV knowledge and higher rates of high-risk behaviour, including earlier sexual debut, multiple sexual partners, participation in commercial sex and recreational drug use. Multivariate logistic regression analysis showed that HIV prevalence among migrant MSM was higher than local MSM (p<0.05). This relationship, however, did not hold for transitional MSM and local MSM (p>0.05). Male sex work, recreational drug use, syphilis infection and HSV-2 infection were independently associated with HIV infection among migrant MSM.ConclusionsNon-local MSM with shorter residence were at greater risk of HIV acquisition. More focus should be placed on HIV behavioural interventions targeting non-local MSM with temporary residence.

HIV infection was positively associated with RD (adjusted odds ratio (AOR), 2.8; 95% confidence interval (CI), 1.4-5.5), practicing RD before sex (AOR, 2.3; 95% CI, 1.2–4.3), practicing RD after sex (AOR, 1.8; 95% CI, 1.0–3.1), using a shower hose for RD (AOR, 3.5; 95% CI, 1.1–13.0), CRAI (AOR, 2.9; 95% CI, 1.6–5.5), and an interaction effect of RD and CRAI (AOR = 4.2; 95 % CI, 2.2- 8.1) in the most recent anal intercourse.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 cohort studies should be conducted to confirm the causal relationship between RD and acquiring HIV.
