Social Media Interventions to Promote HIV Testing, Linkage, Adherence, and Retention: Systematic Review and Meta-Analysis

Background Social media is increasingly used to deliver HIV interventions for key populations worldwide. However, little is known about the specific uses and effects of social media on human immunodeficiency virus (HIV) interventions. Objective This systematic review examines the effectiveness of social media interventions to promote HIV testing, linkage, adherence, and retention among key populations. Methods We used the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) checklist and Cochrane guidelines for this review and registered it on the International Prospective Register of Systematic Reviews, PROSPERO. We systematically searched six databases and three conference websites using search terms related to HIV, social media, and key populations. We included studies where (1) the intervention was created or implemented on social media platforms, (2) study population included men who have sex with men (MSM), transgender individuals, people who inject drugs (PWID), and/or sex workers, and (3) outcomes included promoting HIV testing, linkage, adherence, and/or retention. Meta-analyses were conducted by Review Manager, version 5.3. Pooled relative risk (RR) and 95% confidence intervals were calculated by random-effects models. Results Among 981 manuscripts identified, 26 studies met the inclusion criteria. We found 18 studies from high-income countries, 8 in middle-income countries, and 0 in low-income countries. Eight were randomized controlled trials, and 18 were observational studies. All studies (n=26) included MSM; five studies also included transgender individuals. The focus of 21 studies was HIV testing, four on HIV testing and linkage to care, and one on antiretroviral therapy adherence. Social media interventions were used to do the following: build online interactive communities to encourage HIV testing/adherence (10 studies), provide HIV testing services (9 studies), disseminate HIV information (9 studies), and develop intervention materials (1 study). Of the studies providing HIV self-testing, 16% of participants requested HIV testing kits from social media platforms. Existing social media platforms such as Facebook (n=15) and the gay dating app Grindr (n=10) were used most frequently. Data from four studies show that HIV testing uptake increased after social media interventions (n=1283, RR 1.50, 95% CI 1.28-1.76). In the studies where social media interventions were participatory, HIV testing uptake was higher in the intervention arm than the comparison arm (n=1023, RR 1.64, 95% CI 1.19-2.26). Conclusions Social media interventions are effective in promoting HIV testing among MSM in many settings. Social media interventions to improve HIV services beyond HIV testing in low- and middle-income countries and among other key populations need to be considered.

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.

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).

Faster and Riskier? Online Context of Sex Seeking Among Men Who Have Sex With Men in China

Background Many men who have sex with men (MSM) seek sex partners online, creating barriers and opportunities for human immunodeficiency virus prevention. The purpose of this study was to examine the characteristics of MSM and the risks associated with seeking sex through websites, gay apps, and both platforms in China. Methods Data were collected through a cross-sectional online survey from September through October 2014 from 3 large gay Web portals. Sociodemographic information, sexual behaviors, and online sex seeking behaviors were measured. Multinomial logistic regression was performed to compare sexual risk behaviors among website users, gay app users, and men who used both platforms. Results Of the 1201 participants, 377 (31.4%) were website-only users, 487 (40.5%) were gay app-only users, and 337 (28.0%) were men who used both platforms. These 3 MSM subgroups have distinct sociodemographic characteristics. Overall, 57.6% of participants reported having engaged in condomless anal sex with their last male partner in the past 6 months, but there was no significant difference in condomless sex between the 3 groups. Men who used both platforms viewed more sexually transmitted disease-related messages than website-only users (adjusted odds ratio, 2.19; 95% confidence interval, 1.57–3.05). Conclusions Condom usage behaviors were unaffected by the medium through which sexual partners were found. However, the high frequency of condomless sex suggests that websites and gay apps are both risk environments. This study suggests using multiple platforms for human immunodeficiency virus/sexually transmitted disease social media interventions may be useful.

Crowdsourcing to expand HIV testing among men who have sex with men in China: A closed cohort stepped wedge cluster randomized controlled trial

Background HIV testing rates are suboptimal among at-risk men. Crowdsourcing may be a useful tool for designing innovative, community-based HIV testing strategies to increase HIV testing. The purpose of this study was to use a stepped wedge cluster randomized controlled trial (RCT) to evaluate the effect of a crowdsourced HIV intervention on HIV testing uptake among men who have sex with men (MSM) in eight Chinese cities. Methods and findings An HIV testing intervention was developed through a national image contest, a regional strategy designathon, and local message contests. The final intervention included a multimedia HIV testing campaign, an online HIV testing service, and local testing promotion campaigns tailored for MSM. This intervention was evaluated using a closed cohort stepped wedge cluster RCT in eight Chinese cities (Guangzhou, Shenzhen, Zhuhai, and Jiangmen in Guangdong province; Jinan, Qingdao, Yantai, and Jining in Shandong province) from August 2016 to August 2017. MSM were recruited through Blued, a social networking mobile application for MSM, from July 29 to August 21 of 2016. The primary outcome was self-reported HIV testing in the past 3 months. Secondary outcomes included HIV self-testing, facility-based HIV testing, condom use, and syphilis testing. Generalized linear mixed models (GLMMs) were used to analyze primary and secondary outcomes. We enrolled a total of 1,381 MSM. Most were ≤30 years old (82%), unmarried (86%), and had a college degree or higher (65%). The proportion of individuals receiving an HIV test during the intervention periods within a city was 8.9% (95% confidence interval [CI] 2.2–15.5) greater than during the control periods. In addition, the intention-to-treat analysis showed a higher probability of receiving an HIV test during the intervention periods as compared to the control periods (estimated risk ratio [RR] = 1.43, 95% CI 1.19–1.73). The intervention also increased HIV self-testing (RR = 1.89, 95% CI 1.50–2.38). There was no effect on facility-based HIV testing (RR = 1.00, 95% CI 0.79–1.26), condom use (RR = 1.00, 95% CI 0.86–1.17), or syphilis testing (RR = 0.92, 95% CI 0.70–1.21). A total of 48.6% (593/1,219) of participants reported that they received HIV self-testing. Among men who received two HIV tests, 32 individuals seroconverted during the 1-year study period. Study limitations include the use of self-reported HIV testing data among a subset of men and non-completion of the final survey by 23% of participants. Our study population was a young online group in urban China and the relevance of our findings to other populations will require further investigation. Conclusions In this setting, crowdsourcing was effective for developing and strengthening community-based HIV testing services for MSM. Crowdsourced interventions may be an important tool for the scale-up of HIV testing services among MSM in low- and middle-income countries (LMIC). Trial registration ClinicalTrials.gov NCT02796963

Transplantation or rurality? Migration and HIV risk among Chinese men who have sex with men in the urban areas

Migration of men who have sex with men (MSM) from rural to urban areas is common across low‐ and middle‐income countries and is widely believed to contribute to elevated HIV risk among migrant MSM in urban areas. Little consensus exists on whether their risk is due to their transplantation or their being from resource‐constrained rural areas. This study seeks to clarify the relationship between migration and HIV risks by comparing differences in HIV‐related risky sexual behaviours and healthcare utilization across competing conceptualizations of migratory statuses.

Leading by example: online sexual health influencers among men who have sex with men have higher HIV and syphilis testing rates in China (Preprint)

Background The spread of healthy behaviors through social networks may be accelerated by influential individuals. Previous studies have used lay health influencers to prevent sexually transmitted infections (STIs) among internet-using men who have sex with men (MSM). However, there is a lack of understanding of the characteristics of this key subset of MSM. Objective This study aimed to examine sociodemographic characteristics, HIV and syphilis testing, and sexual behaviors of Web-based MSM sexual health influencers (SHIs) in China, defined as individuals with relatively stronger influence on spreading HIV and STI information online. Methods A Web-based survey of MSM was conducted in August 2017 as a final follow-up of a randomized controlled trial promoting HIV testing in 8 Chinese cities. Men were recruited through a gay social networking mobile phone app and were included if they were born biologically male, aged 16 years and above, ever had sex with another man, and HIV negative or with unknown HIV status. Information regarding sociodemographic characteristics, sexual behaviors, and HIV and syphilis testing was obtained. We assessed men’s Web-based sexual health influence using a standardized 6-item opinion leadership scale focused on HIV and STI information. Influencers were defined as those whose mean score ranked within the top 13% (a higher score means greater influence). We used multivariable linear and logistic regression models to measure Web-based sexual health influence’s association with HIV and syphilis testing, controlling for intervention trial effects, age, education, income, and marital status. Results Overall, 1031 men completed the survey. Most men were younger than 30 years (819/1031, 79.43%) and had at least college education (667/1031, 64.69%). Influencers were more likely to get tested for HIV (73/132, 55.3% vs 337/899, 37.5%; P<.001) and syphilis (35/132, 26.5% vs 137/899, 15.2%; P=.001) in the last 3 months compared with noninfluencers. There were no significant differences in condomless sex with male partners (26/132, 19.7% vs 203/899, 22.6%; P=.46), mean number of male sex partners (1.32 vs 1.11; P=.16) in the last 3 months, and mainly meeting male sex partners online in the last 12 months (97/132, 73.5% vs 669/899, 74.4%; P=.82) between influencers and noninfluencers. Regression analyses showed that influencers had higher odds of HIV testing (adjusted odds ratio, AOR 2.16, 95% CI 1.48-3.17) and syphilis testing (AOR 1.99, 95% CI 1.28-3.10) in the last 3 months. Conclusions We identified Web-based SHIs who might be more likely to help promote healthy HIV and syphilis testing behaviors through MSM populations. Leveraging existing influencers may help improve HIV and syphilis testing among their networks.

The Online Physician is Ready to See You: A Nationwide Cross-sectional Survey of Physicians Using A Mobile App to Evaluate Sexually Transmitted Disease (STD) Patients in China (Preprint)

Background Web-based medical service provision is increasingly becoming common. However, it remains unclear how physicians are responding to this trend and how Web-based and offline medical services are linked. Objective The objectives of this study were to examine physicians’ use of mobile medical apps for sexually transmitted disease (STD) consultations and identify the physicians who frequently use mobile medical apps to evaluate patients with STD. Methods In August 2017, we conducted a nationwide cross-sectional survey among physicians registered on a mobile medical app in China. We collected data on physicians’ demographic information, institutional information, and Web-based medical practices. We compared physicians who used mobile medical apps to evaluate patients with STD frequently (at least once a week) with infrequent users. Bivariate and multivariate logistic regressions were used to identify physicians who frequently evaluated patients with STD on mobile medical apps. Results A total of 501 physicians participated in the survey. Among them, three-quarters were men and the average age was 37.6 (SD 8.2) years. Nearly all physicians (492/501, 98.2%) recommended their last Web-based patient with STD to subsequently see a physician in the clinic. More than half (275/501, 54.9%) of physicians recommended STD testing to Web-based patients, and 43.9% (220/501) provided treatment advice to patients with STD. Of all physicians, 21.6% (108/501) used mobile medical apps to evaluate patients with STD through Web more than once a week. Overall, 85.2% (427/501) physicians conducted follow-up consultation for patients with STD using mobile medical apps. Physicians working at institutions with STD prevention materials were associated with frequent evaluation of patients with STD on mobile medical apps (adjusted odds ratio=2.10, 95% CI 1.18-3.74). Conclusions Physicians use mobile medical apps to provide a range of services, including Web-based pre- and posttreatment consultations and linkage to offline clinical services. The high rates of referral to clinics suggest that mobile medical apps are used to promote clinic-seeking, and not replace it. Physicians’ use of mobile medical apps could benefit sexual minorities and others who avoid formal clinic-based services.

Linking young men who have sex with men (YMSM) to STI physicians: a nationwide cross-sectional survey in China

BackgroundMany young men who have sex with men (YMSM) are reluctant to seek health services and trust local physicians. Online information seeking may encourage YMSM to identify and see trustworthy physicians, obtain sexual health services, and obtain testing for sexually transmitted infections (STIs). This study examined online STI information seeking behaviors among Chinese YMSM and its association with offline physician visits.MethodsWe conducted a nationwide online survey among YMSM through WeChat, the largest social media platform in China. We collected information on individual demographics, sexual behaviors, online STI information seeking, offline STI testing, and STI physician visits. We examined the most commonly used platforms (search engines, governmental websites, counseling websites, generic social media, gay mobile apps, and mobile medical apps) and their trustworthiness. We assessed interest and willingness to use an MSM-friendly physician finder function embedded within a gay mobile app. Logistic regression models were used to examine the correlation between online STI information searching and offline physician visits.ResultsA total of 503 men completed the survey. Most men (425/503, 84.5%) searched for STI information online. The most commonly used platform to obtain STI information were search engines (402/425, 94.5%), followed by gay mobile apps (201/425, 47.3%). Men reported high trustworthiness of information received from gay mobile apps. Men also reported high interest (465/503, 92.4%) and willingness (463/503, 92.0%) to use a MSM-friendly physician finder function within such apps. Both using general social media (aOR =1.14, 95%CI: 1.04–1.26) and mobile medical apps (aOR =1.16, 95%CI: 1.01–1.34) for online information seeking were associated with visiting a physician.ConclusionOnline STI information seeking is common and correlated with visiting a physician among YMSM. Cultivating partnerships with the emerging mobile medical apps may be useful for disseminating STI information and providing better physician services to YMSM.

The interaction between social norm and self-efficacy on HIV testing among Chinese men who have sex with men: results from an online cross-sectional study

Abstract Background Increased HIV testing is an effective strategy for HIV control among key populations, including men who have sex with men (MSM). We aimed to examine the interaction between social norms related to HIV testing and self-efficacy of HIV testing among Chinese MSM. Methods A cross-sectional online survey was conducted in eight Chinese cities in Shandong and Guangdong provinces in July 28–31, 2016. The inclusion criteria included: born as a male, age at least 16 years old, ever engaged in anal sex with men, and currently living in one of the designated cities. Information regarding sociodemographics, risk behaviours, and testing history for HIV and other sexually transmitted infections were collected. Social norm was operationalised by six items asking participants about the social norms of HIV testing. HIV testing self-efficacy was measured with a six-item scale. Higher mean scores indicated higher self-reported strength of social norms and self-efficacy for HIV testing. Univariate and multivariate logistic regressions were used to evaluate the interaction between self-efficacy and social norm on HIV testing. Findings 2105 men completed the survey. The mean age of the participants was 25·97 years (SD 6·42). More than four-fifths (1809 [86%]) of participants were unmarried, 477 (23%) were students, and 1359 (65%) had at least a college degree. Overall, 1315 (62%) participants had been ever tested for HIV, and 687 (33%) had been tested in the past 3 months. 685 (33%) had ever HIV self-tested in their lifetime. The main effect estimate on HIV testing in the past 3 months was 1·01 (95% CI 0·96–1·06) for social norm and 1·09 (95% CI 1·05–1·14) for self-efficacy, with an interaction effect of 1·02 (95% CI 1·01–1·03). Interpretation Our survey demonstrated the interaction between self-efficacy and social norm on HIV testing among Chinese MSM. Further research and interventions to increase self-efficacy and social norm on HIV testing are needed.
