Recreational drug use among Chinese MSM and transgender individuals: Results from a national online cross-sectional study

Background Recreational drug use has increased considerably among Chinese men who have sex with men (MSM). The phenomenon has the potentially to increase HIV transmission among Chinese MSM. The aims of this study were: 1) to investigate the prevalence of recreational drug use among Chinese MSM, and 2) to explore the correlation between gay smartphone based sex-seeking applications (gay apps), HIV/STIs testing, group sex, commercial sex, sexual roles and poppers use among Chinese MSM. Methods MSM who were born biologically male, were at least 16 years of age and had engaged in anal sex with a man at least once were recruited through a nation-wide online survey in 2014. Information regarding socio-demographics, risk behaviors, recreational drug use, HIV and other STIs testing history and gay app use were collected. Univariate and multivariate analysis were used to determine factors associated with recreational drug use among Chinese MSM. Results Among 1424 participating MSM, 1100 (77.3%) reported ever using recreational drugs in their lifetime. In the last 12 months, 303 (21.3%) used poppers, 34 (2.4%) used crystal meth and 15 (1.0%) used ecstasy. The mean age of respondents was 25.6±6.8 years, 72.9% identified as gay, 41.3% were students, and 83.8% had never been married. Multiple logistic regression models revealed that compared with non-popper users, popper users were more likely to have been tested for HIV (adjusted OR (aOR) = 1.50, 95% CI: 1.15–1.96) and other STIs (aOR = 1.65, 95% CI: 1.26–2.17). In addition, popper users were more likely to engage in group sex (aOR = 2.63, 95% CI:1.80–3.86), commercial sex (aOR = 1.86, 95% CI:1.13–3.06) and used gay mobile apps to seek sexual partners (aOR = 2.10, 95% CI:1.58–2.80). Conclusion Chinese MSM has a high rate of recreational drug use, including poppers. Public health programs serving MSM may consider integrating intervention programs to decrease recreational drug use related harms.

Comparing the effectiveness of a crowdsourced video and a social marketing video in promoting condom use among Chinese men who have sex with men: a study protocol.

Introduction Crowdsourcing has been used to spur innovation and increase community engagement in public health programmes. Crowdsourcing is the process of giving individual tasks to a large group, often involving open contests and enabled through multisectoral partnerships. Here we describe one crowdsourced video intervention in which a video promoting condom use is produced through an open contest. The aim of this study is to determine whether a crowdsourced intervention is as effective as a social marketing intervention in promoting condom use among high-risk men who have sex with men (MSM) and transgender male-to-female (TG) in China. Method We evaluate videos developed by crowdsourcing and social marketing. The crowdsourcing contest involved an open call for videos. Entries were judged on capacity to promote condom use, to be shareable or ‘go viral’ and to give value to the individual. 1170 participants will be recruited for the randomised controlled trial. Participants need to be MSM age 16 and over who have had condomless anal sex in the last 3 months. Recruitment will be through an online banner ad on a popular MSM web page and other social media platforms. After completing an initial survey, participants will be randomly assigned to view either the social marketing video or the crowdsourcing video. Follow-up surveys will be completed at 3 weeks and 3 months after initial intervention to evaluate condomless sex and related secondary outcomes. Secondary outcomes include condom social norms, condom negotiation, condom self-efficacy, HIV/syphilis testing, frequency of sex acts and incremental cost. Ethics and dissemination Approval was obtained from the ethical review boards of the Guangdong Provincial Center for Skin Diseases and STI Control, UNC and UCSF. The results of this trial will be made available through publication in peer-reviewed journals. Trial registration number NCT02516930.

Disclosure of sexual orientation to health professionals in China: results from an online cross-sectional study

Background: Many men who have sex with men (MSM) in China are “in the closet.” The low rate of disclosure may impact sexual behaviours, testing for HIV and other sexually transmitted infections (STIs), and diseases transmission. This study examines factors associated with overall sexual orientation disclosure and disclosure to healthcare professionals.

Innovation contests to promote sexual health in china: a qualitative evaluation

BackgroundInnovation contests call on non-experts to help solve problems. While these contests have been used extensively in the private sector to increase engagement between organizations and clients, there is little data on the role of innovation contests to promote health campaigns. We implemented an innovation contest in China to increase sexual health awareness among youth and evaluated community engagement in the contest.MethodsThe sexual health image contest consisted of an open call for sexual health images, contest promotion activities, judging of entries, and celebrating contributions. Contest promotion activities included in-person and social media feedback, classroom didactics, and community-driven activities. We conducted 19 semi-structured interviews with a purposive sample to ensure a range of participant scores, experts and non-expert participants, submitters and non-submitters. Transcripts of each interview were coded with Atlas.ti and evaluated by three reviewers.ResultsWe identified stages of community engagement in the contest which contributed to public health impact. Community engagement progressed across a continuum from passive, moderate, active, and finally strong engagement. Engagement was a dynamic process that appeared to have little relationship with formally submitting an image to the contest. Among non-expert participants, contest engagement increased knowledge, healthy attitudes, and empowered participants to share ideas about safe sex with others outside of the contest. Among experts who helped organize the contest, the process of implementing the contest fostered multi-sectoral collaboration and re-oriented public health leadership towards more patient-centered public health campaigns.ConclusionThe results of this study suggest that innovation contests may be a useful tool for public health promotion by enhancing community engagement and re-orienting health campaigns to make them more patient-centered.

HIV self-testing among high-risk men who have sex with men in China: a cross-sectional study

BACKGROUND HIV self-testing holds great promise for reaching high-risk key populations who do not access facility-based services, but it has rarely been evaluated outside of structured research settings. HIV self-testing is a process by which a person takes and interprets a test. We aimed to characterise implementation of unsupervised HIV self-testing among men who have sex with men (MSM) in China. METHODS We undertook a nationwide online survey of MSM in November, 2015, in China. Men were invited to participate by clicking through banner adverts on social network sites. Eligible men were at least 16 years of age, had ever had anal sex with a man, and had had sex without use of a condom in the past 3 months. Among MSM who ever self-tested for HIV, we assessed benefits (eg, first-time HIV test, increased testing frequency, confirmatory testing) and adverse outcomes, (eg, coercion, violence, suicidality). First-time HIV test was defined by what an individual reported was their first ever test for HIV (a self-test or a facility test). Among MSM who reported ever testing for HIV, we identified correlates of HIV self-testing as first-time HIV test with use of multivariable logistic regression. The institutional review boards of the Guangdong Provincial Center for Skin Diseases and STI Control, the University of North Carolina at Chapel Hill, and the University of California San Francisco approved this study. FINDINGS Of 1610 eligible men, 1189 (73·9%) completed the survey. 28·7% (341/1189) reported ever self-testing for HIV. The HIV prevalence among self-testers was 7·0% (24/341) and among non-self-testers was 4·9% (15/306). Among self-testers, 58·7% (200/341) reported HIV self-testing as a first-time HIV test and 22·6% (77/341) had increased testing frequency. 77·5% (31/40) of those with a positive HIV self-test received confirmatory facility-based testing. Minimal adverse outcomes were noted. Multivariable analysis showed that self-testing as first-time HIV test was associated with younger age (odds ratio 0·95, 95% CI 0·91-0·99), not telling health-care providers about having sex with men (2·22, 1·56-3·17), not using the internet to meet sex partners (2·53, 1·45-4·43), and having group sex (1·76, 1·03-2·98). INTERPRETATION HIV self-testing increases first-time HIV testing and testing frequency among those with previous testing. This tool could be useful to scale up HIV testing among high-risk men in China and other settings.

Will Gay Sex–Seeking Mobile Phone Applications Facilitate Group Sex? A Cross-Sectional Online Survey among Men Who Have Sex with Men in China

Introduction China is amidst a sexual revolution, with changing sexual practices and behaviors. Sex–seeking mobile phone applications (gay apps) that allow multiple people to meet up quickly may facilitate group sex. This study was therefore undertaken to evaluate group sex among Chinese MSM and to better understand factors associated with group sex. Methods An online survey was conducted from September-October 2014, collecting data on socio-demographics, sexual behaviors, use of gay apps and occurrence of group sex among Chinese MSM. Univariate and multivariable logistic regressions were used to compare group sex and non-group sex participants. Results Of the 1,424 MSM, the majority were under 30 years old (77.5%), unmarried (83.9%), and were gay apps users (57.9%). Overall, 141 (9.9%) participants engaged in group sex in the last 12 months. Multivariate analyses showed that men living with HIV, engaged in condomless anal intercourse with men, and used gay apps were more likely to engage in group sex, with adjusted ORs of 3.74 (95% CI 1.92–7.28), 2.88 (95% CI 2.00–4.16) and 1.46 (95% CI: 1.00–2.13), respectively. Among gay app users, the likelihood of group sex increases with the number of sex partners and the number of sex acts with partners met through a gay app. Conclusions Chinese MSM who engage in group sex are also more likely to engage in other risky sexual behaviors, and gay app use may facilitate group sex. Further research is needed among MSM who engage in group sex in order to target interventions and surveillance.

Crowdsourcing designathon: a new model for multisectoral collaboration

Public health programmes are frequently developed by experts with limited feedback from communities.1 Crowdsourcing, allowing a group to solve a problem and then sharing the solution with the public, may help to improve public health programmes. Crowdsourcing can often take the form of participatory contests.2 Previous crowdsourcing contests have focused on producing individual components of communication programmes, such as videos,3 4 images5 6 or logos.7 However, crowdsourcing contests have not focused on designing the final programme and plan for implementation. The purpose of this project was to crowdsource the development of an HIV testing programme using a designathon. The concept of a crowdsourcing designathon is related to, but distinct from, a hackathon. Hackathons are intensive, approximately 72-hour contests that bring together young people to complete a task.8 9 For example, hackathons organised by a university have brought together students and others interested in technology to create a mobile application.10 Medical hackathons have challenged participants to create devices that help people with dementia, disability and other illnesses.9 11 12 We propose the concept of a crowdsourcing designathon, drawing on the principles of crowdsourcing in order to design a public health programme with strong community input. The purpose of this article is to describe a crowdsourcing designathon, summarise designathon outputs and discuss designathon implications for public health. The purpose of our crowdsourcing designathon was to develop a community-based HIV testing programme to be implemented in eight Chinese cities. This concept was influenced by theories of crowdsourcing13 and community-based participatory research.14 Our designathon was implemented in the following steps: forming a local steering committee; open call for participants; prepare for the event; 72-hour implementation; sustaining engagement and evaluation (table 1).

Crowdsourcing health communication about condom use in men who have sex with men in China: a randomised controlled trial.

BACKGROUND The Chinese government now encourages innovation, and more specifically, crowdsourcing. Crowdsourcing, the process of shifting individual tasks to a large group, might reimagine health communication, making it more people-centred. We aimed to compare the effectiveness of a crowdsourced versus social marketing condom promotion video to promote condom use. METHODS A non-inferiority randomised controlled trial was conducted in November 2015 in China. Men who have sex with men (MSM) aged 16 years or older who reported having had sexual contact without use of a condom in the preceding 3 months were recruited through a nationwide MSM website. Men were randomly allocated to one of the two arms in a 1:1 ratio using a computer algorithm and then watched one of two videos. The crowdsourced video was developed through an open contest and the social marketing video was designed by a company. Participants completed a baseline survey and follow-up surveys at 3 weeks and 3 months post-intervention. The primary outcome was incidence of sexual contact without a condom. Intention-to-treat analysis was used, with a non-inferiority margin of 10%. The trial is registered with ClinicalTrials.gov, number NCT02516930. All participants gave informed consent and the protocol was approved by Chinese (Guangdong Provincial Centre for Skin Diseases and STI Control) and American (University of North Carolina at Chapel Hill and the University of California San Francisco) institutional review boards. FINDINGS 1173 participants were recruited to the study; 907 (77%) completed the 3-week follow up and 791 (67%) the three-month follow up. At three weeks, 146/434 (33·6%) participants in the crowdsourced group and 153/473 (32·3%) in the social marketing group reported having sexual contact without a condom. The crowdsourced intervention achieved our pre-specified non-inferiority criterion (estimated difference: +1·3% [95%CI: 4·8-7·4]). At 3 months, 196/376 (52·1%) men in the crowdsourced group and 206/415 (49·6%) in the social-marketing group reported having sexual contact without a condom (estimated difference: +2·5% [95%CI -4·5-9·5%]). The two groups reported similar HIV testing rates and other condom-related secondary outcomes. The cost of the crowdsourcing intervention was substantially lower than the social marketing intervention (16 686 vs 26 845 USD). No adverse outcomes were reported. INTERPRETATION Crowdsourcing could be a useful tool in China, which has a large population and government support. Crowdsourcing provides a structured system for multi-sectoral input into health policy in China.

Disclosure of sexual orientation in men who have sex with men in China: a cross-sectional survey

BACKGROUND Most men who have sex with men (MSM) in China do not publicly disclose their sexual orientation. This low rate of disclosure may affect sexual behaviours, testing for HIV or other sexually transmitted infections (STIs), and disease transmission. This study examined factors associated with overall sexual orientation disclosure and disclosure to a healthcare professional. METHODS We did a cross-sectional online survey of MSM in China from September 23, 2014, to October 8, 2014, through three national websites. Participants completed questions covering sociodemographic information, sexual behaviors, HIV and syphilis test history, and self-reported HIV status. We defined overall disclosure as having ever disclosed sexual orientation to anyone other than a sexual partner, and healthcare professional disclosure as disclosing to a doctor or other medical provider. Eligible participants gave informed consent electronically before beginning the survey. FINDINGS A total of 1819 men started the survey and 1424 (78%) completed it. Of 1424 participants, 62% (886/1424) reported overall disclosure, and 16% (232/1424) had disclosed to healthcare providers. In multivariate analyses, the odds of overall sexual orientation disclosure were 56% higher among MSM who used smartphone-based sex-seeking applications (adjusted OR 1·56 [95% CI 1·25-2·95]), but were lower among MSM reporting high-risk sexual risk behaviors such as sex while drunk (0·55 [0·37-0·81]) and sex while using drugs (0·66 [0·50-0·87]). The odds of disclosure to a healthcare professional were greater among MSM who had ever been tested for HIV (3·36 [2·50-4·51]) or STIs 4·92 [3·47-6·96]) or self-reported as HIV positive (1·59 [0·93-2·72]). INTERPRETATION More than 80% of MSM surveyed had not disclosed their sexual orientation to health professionals. This low level of disclosure probably represents a major obstacle to serving the unique needs of MSM in clinical settings. Further research and action to facilitate disclosure of sexual orientation by MSM, especially to healthcare professionals, is urgently needed.

Condomless Vaginal Intercourse and Its Associates among Men Who Have Sex with Men in China.

Background HIV prevalence has increased rapidly among men who have sex with men (MSM) in China reaching alarmingly high levels in some cities. Bisexual MSM have potential to transmit HIV and syphilis to their female partners through condomless vaginal intercourse (CVI). Thus, estimation of the burden of CVI and identification of its associates seemed necessary to control this cross-gender transmission. Method In a cross-sectional study, using respondent-driven-sampling and snowball sampling, 2958 MSM were recruited from seven Chinese cities, interviewed and tested for HIV and syphilis. Descriptive analysis of the socio-demographic and behaviors followed by simple and multiple logistic regressions [adjusted for income, city, race and social network size to determine adjusted odds ratio (aOR)] were performed using SAS-9.1. Results Among participating MSM, 19.03% were engaged in CVI. Prevalence of HIV and syphilis among participants involved in CVI were 5.86% and 14.74% respectively. MSM who were older [aOR for aged 40–49 = 2.60 (95% CI: 1.54–4.37)], married [aOR = 6.13 (4.95–7.58)], attended primary school or below [aOR = 3.86 (2.26–6.69)], met male partners at spa/bathhouse/sauna/massage parlor [aOR = 3.52 (2.62–4.72)] and had heterosexual orientation [aOR = 13.81 (7.14–26.70)] were more likely to have CVI. Furthermore, correct knowledge regarding HIV [aOR = 0.70 (0.55, 0.88)] and exposure to HIV prevention interventions [aOR = 0.67 (0.54, 0.82)] were negatively associated with CVI. Conclusions CVI was found to be common among MSM in China. To minimize the transmission of HIV and syphilis from bisexual MSM to their relatively female partners, targeted interventions should specifically focus on bisexual MSM especially the older and married subgroups.
