Internet-based cohort study of HIV testing over 1 year among men who have sex with men living in England and exposed to a social marketing intervention promoting testing

An application of social marketing for promoting HIV testing in Iran

BACKGROUND

It has been estimated that 60,000 Iranians have been infected with HIV/AIDS and only 36% of them are aware of their status. This study aimed to design, implement and evaluate a social marketing campaign to promote HIV testing in Boyer-Ahmad County, Kohgiluyeh, and Boyer-Ahmad Province, southwest of Iran.

MATERIALS AND METHODS

This study was a quasi-experimental pretest-posttest without a control group, developed based on a social marketing assessment and response tool. To design the intervention formative research was conducted, comprised of four focus group discussion sessions with 42 participants of the target community along with seven in-depth semi-structured personal interviews with health care providers involved in the HIV/AIDS Program. Data analysis was done manually using content analysis and the main content was formulated for the campaign. Afterward, the slogan and messages of the campaign were developed. The campaign's materials including banners, posters, pamphlets, referral forms, and short messages were designed, pretested, and revised. Ultimately, the campaign was conducted for one month in October 2019. To determine the effectiveness of the campaign, the rate of referrals to the Center for Behavioral Health Counseling Services (CBHCS), for three months before and after the campaign, was compared.

RESULTS

Qualitative findings identified that the majority of the interviewees mentioned that the main reasons for the low rate of referrals to get tested for HIV were lack of awareness and information about HIV/AIDS and its diagnosis as well as the free and confidential tests available from the CBHCS. Moreover, the stigma associated with HIV/AIDS was another important reason for low referrals for testing. The rate of referrals for HIV testing in the three months leading up to the campaign was 18, 32, and 23 people, and three months after the campaign was 64, 81, and 44 individuals; respectively. The results of the multivariate analysis demonstrated that the campaign had increased the rates of referrals for HIV testing through its significant influence on females, and individuals with academic degrees.

CONCLUSION

It can be concluded that the social marketing campaign was successful in persuading people to get tested for HIV.

Strategies to increase HIV testing among men who have sex with men and transgender women: an integrative review

BACKGROUND

Men who have sex with men (MSM) and transgender women (TGW) are disproportionately affected by HIV, with much higher incidence and prevalence rates than in the general population in different countries. There are several barriers to testing among MSM and TGW, such as low risk perception, anticipation of HIV-related stigma, discrimination of sexual orientation, in addition to difficulties related to care and access to health services. Therefore, analyzing the available evidence of the effectiveness of strategies for scaling up HIV testing among key populations is essential to point out potential knowledge gaps which may need to be addressed and develop public health policies to promote testing and early diagnosis of HIV infection.

METHODS

An integrative review was carried out to evaluate strategies for scaling up HIV testing in these populations. Search strategy was performed on eight electronic databases, without language restriction. We included clinical trials, quasi-experimental studies, and non-randomized studies. Study selection and data extraction were both performed independently by pairs and disagreements were solved by a third revisor. The screening of the studies was carried out through the selection of titles/abstracts and the reading of the full texts of the pre-selected studies based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). Data extraction was performed using a structured form.

RESULTS

Thirty-seven publications referring to 35 studies were included, mostly being carried out in the United States of America and Australia. No studies were found evaluating disaggregated data on TGW. The studies were grouped into four types of intervention strategies: self-test distribution system (n = 10), organization of health services (n = 9), peer education (n = 6), and social marketing campaign (n = 10). Strategies that focused on the first three groups, combined or not, were more effective in increasing HIV testing among MSM.

CONCLUSIONS

Considering the diversity of interventions and the methodological heterogeneity of the included studies, strategies especially involving self-test distribution systems, associated with new information and communication technologies, should be evaluated in different communities and social contexts. Research evaluating specific studies on TGW population is still needed.

Impact of Social Media Use on HIV Testing and Related Mediator among Men Who Have Sex with Men in Shandong Province, China

In China, HIV testing is the important first step of HIV prevention and treatment cascades but is not widely adopted by men who have sex with men (MSM). However, social media has been increasingly used to promote and improve HIV testing. This study aimed to assess the impact of social media use on HIV testing and explore the mediator in the relationship between social media and HIV testing. The authors conducted a cross-sectional study among 935 MSM participants in 11 cities in Shandong Province from 14 September to 6 December 2020. Multivariable regression was conducted to assess the relationship between social media use and HIV testing uptake, and mediation analysis was used to assess the mediation effect of HIV testing self-efficacy in the relationship between social media use and HIV testing. The present study findings showed that social media use was related to HIV testing (aOR = 3.024, 95% CI: 1.869, 4.892) and HIV self-testing uptake (aOR = 1.894, 95% CI: 1.228, 2.922), but was not related to HIV facility-based testing (aOR = 1.709, 95% CI: 0.806, 3.625, p = 0.162). A mediation effect of HIV testing self-efficacy was found between social media use and HIV testing (indirect effect: 0.13, 95% CI: 0.01, 0.29), facility-based testing (indirect effect: 0.05, 95% CI: 0.003, 0.16), and self-testing uptake (indirect effect: 0.07, 95% CI: 0.01, 0.16). Social media could be an effective tool to improve HIV testing, and healthcare providers should pay more attention to HIV testing self-efficacy in HIV testing promotion.

Digital Epidemiologic Research on Multilevel Risks for HIV Acquisition and Other Health Outcomes Among Transgender Women in Eastern and Southern United States: Protocol for an Online Cohort

BACKGROUND

The HIV epidemic disproportionately impacts transgender women in the United States. Cohort studies identify unique risks for affected populations, but use of facility-based methods may bias findings towards individuals living in research catchment areas, more engaged in health services, or, in the case of transgender populations, those who are open about their transgender identity. Digital clinical trials and other online research methods are increasingly common, providing opportunity to reach those not commonly engaged in research. Simultaneously, there is a need to understand potential biases associated with digital research, how these methods perform, and whether they are accepted across populations.

OBJECTIVE

This study aims to assess the feasibility of developing and implementing an online cohort of transgender women to assess risks for HIV acquisition and other health experiences. Further, this study aims to evaluate how an online cohort compares to a site-based, technology-enhanced cohort for epidemiologic research. The overarching goal is to estimate incidence of HIV and other health outcomes among transgender women in eastern and southern United States.

METHODS

This substudy is part of a larger multisite prospective cohort (LITE) conducted among transgender women, which also includes a site-based, technology-enhanced cohort in 6 eastern and southern US cities. The online cohort was launched to enroll and follow participants across 72 cities in the same region and with similar demographic characteristics as the site-based cohort. Participants are followed for 24 months. Adult transgender women are recruited via convenience sampling (eg, peer referrals, social media, and dating apps). Participants reporting negative or unknown HIV status are enrolled in a baseline study visit, complete a sociobehavioral survey, and provide oral fluid specimens to test for HIV. Participants not living with HIV (lab-confirmed) at baseline are offered enrollment into the cohort; follow-up assessments occur every 6 months.

RESULTS

Enrollment into the online cohort launched in January 2019. Active recruitment stopped in May 2019, and enrollment officially closed in August 2020. A total of 580 participants enrolled into and are followed in the cohort. A recruitment-enrollment cascade was observed across screening, consent, and completion of study activities. Implementation experiences with HIV test kits highlight the need for heavy staff engagement to support participant engagement, visit completion, and retention, even with automated digital procedures.

CONCLUSIONS

This study is responsive to increasing research interest in digital observational and intervention research, particularly for populations who are most affected by the HIV epidemic and for those who may otherwise not participate in person. The progression across stages of the recruitment-enrollment cascade provides useful insight for implementation of cohort studies in the online environment.

A qualitative examination of affect and ideology within mass media interventions to increase HIV testing with gay men garnered from a systematic review

OBJECTIVES

Increasing appropriate HIV testing among men who have sex with men (MSM) is crucial to HIV prevention. Mass media interventions are effective in promoting testing, but to date, there has been little examination of their active content.

DESIGN

We conducted a qualitative analysis of intervention materials (n = 69) derived from a systematic review of mass media interventions designed to improve testing with MSM.

METHODS

Visual data were analysed for their affective and ideological content using a novel method drawing on concepts from semiotics (i.e., broadly speaking, the analysis of signs).

RESULTS

Whilst affect was not explicitly theorized or examined in any of the studies, there are clearly identifiable affective elements implicitly at play in these interventions. Four thematic categories of affect/ideology were identified including (1) sexual desire and the 'pornographication' of the gay/bisexual male subject; (2) narratives of romance and love; (3) fear, threat, and regret; and (4) 'flattened' affect.

CONCLUSIONS

This is the first study to examine and detail the affective and ideological aspects of intervention content in this field. Using analytic techniques such as those reported here, in addition to approaches that focus on the manner in which intervention content address more proximal determinants of behaviour, can provide a rich and potentially more useful evidence base to assist with future interventions.

Mass media and communication interventions to increase HIV testing among gay and other men who have sex with men: Social marketing and visual design component analysis

Mass media and communication interventions can play a role in increasing HIV testing among gay, bisexual and other men who have sex with men (GBMSM). Despite the key role of social marketing principles and visual design within intervention development of this type, evidence is limited regarding interventions’ social marketing mix or visual design. As part of a systematic review, intervention content was assessed using social marketing theory and social semiotics. Data were extracted on the nature of the intervention, mode of delivery, use of imagery, content and tone and the eight key characteristics of social marketing. Data were synthesised narratively. Across the 19 included studies, reference to social marketing principles was often superficial. Common design features were identified across the interventions, regardless of effectiveness, including: the use of actors inferred to be GBMSM; use of ‘naked’ and sexually explicit imagery; and the use of text framed as statements or instructions. Our results suggest that effective interventions tended to use multiple modes of delivery, indicating high social marketing complexity. However, this is only part of intervention development, and social marketing principles are key to driving the development process. We identified consistent aspects of intervention design, but were unable to determine whether this is based on evidence of effectiveness or a lack of originality in intervention design. An openness to novel ideas in design and delivery is key to ensuring that evidence-informed interventions are effective for target populations.

The Effectiveness of Social Marketing Interventions to Improve HIV Testing Among Gay, Bisexual and Other Men Who Have Sex with Men: A Systematic Review

HIV testing is central to biomedical HIV prevention, but testing among men who have sex with men remains suboptimal. We evaluated effectiveness of mass media and communication interventions to increase HIV testing and explored patterns between study type, internal validity and intervention effectiveness for the first time. Five databases were searched for articles published between 2009 and 2016 using standard MeSH terms. Eligible studies were quality appraised using standard checklists for risk of bias. Data were extracted and synthesised narratively. Nineteen studies met inclusion criteria; 11 were cross-sectional/non-comparative studies, four were pre/post or interrupted time series, three were randomised controlled trials (RCTs) and one was a case study. Risk of bias was high. Five cross-sectional (two graded as high internal validity, one medium and two low) and one RCT (medium validity) reported increased HIV testing. Further work is required to develop and evaluate interventions to increase frequency and maintenance of HIV testing.

What are mass media interventions made of? Exploring the active content of interventions designed to increase HIV testing in gay men within a systematic review

PURPOSE

Mass media HIV testing interventions are effective in increasing testing, but there has been no examination of their theory or behaviour change technique (BCT) content. Within a heterogeneous body of studies with weak evaluative designs and differing outcomes, we attempted to gain useful knowledge to shape future interventions.

METHODS

Within a systematic review, following repeated requests to the authors of included studies for intervention materials, the Theory Coding Scheme, the Theoretical Domains Framework (TDF), and Behaviour Change Technique Taxonomy (BCTT) were used to extract data relating to active intervention content.

RESULTS

Of 19 studies, five reported an explicit theoretical basis to their intervention. TDF analysis highlighted the key domains employed within the majority of interventions: 'knowledge', 'social roles and identities', and 'beliefs about consequences'. BCT analysis showed three BCT groupings commonly reported within interventions: 'Comparison of outcomes', 'Natural consequences', and 'Shaping knowledge'. Three individual BCTs formed the backbone of most interventions and can be considered 'standard' content: 'Instructions on how to perform behaviour'; 'Credible source'; and 'Information about health consequences'.

CONCLUSIONS

This is the first study to examine and detail active intervention content in this field. It suggests future interventions should improve knowledge about testing, and use well-branded and trusted sources that endorse testing. Future interventions should also provide clear information about the health benefits of testing. Our analysis also suggests that to improve levels of effectiveness characterizing the current field, it may be useful to elicit commitment, and action plans, relating to how to implement testing intentions.

STATEMENT OF CONTRIBUTION

What is already known on this subject? Interventions are urgently needed to increase HIV testing among men who have sex with men (MSM) and enable increased access to effective treatment for HIV infection. There is some evidence of the effectiveness of mass media interventions in increasing HIV testing among MSM. Nothing is known about the active components of existing mass media interventions targeting HIV testing. What does this study add? It describes the available literature concerning evaluated mass media interventions to increase HIV testing. It shows few interventions report any explicit theoretical basis although many interventions share common components, including coherently connected causal mechanisms and behaviour change techniques to moderate them. As a minimum, future interventions should improve knowledge about testing; use well-branded and trusted sources that endorse testing; and provide clear information about the health benefits of testing. Our analysis also tentatively suggests it may be useful to elicit commitment and planning of how to implement testing intentions.

HIV testing intervention development among men who have sex with men in the developed world

HIV testing is a 'gateway' technology, enabling access to treatment and HIV prevention. Biomedical approaches to prevention, such as pre-exposure prophylaxis and treatment as prevention, require accurate and regular HIV test results. HIV testing also represents a powerful 'teachable moment' for behavioural prevention. An increasing range of HIV tests and the emergence of self-managed diagnostic technologies (e.g. self-testing) means there is now considerable diversification of when, where and how results are available to those who test. These changes have profound implications for intervention development and, indeed, health service redesign. This paper highlights the need for better ways of conceptualising testing in order to capitalise on the health benefits that diverse HIV testing interventions will bring. A multidimensional framework is proposed to capture ongoing developments in HIV testing among men who have sex with men and focus on the intersection of: (1) the growing variety of HIV testing technologies and the associated diversification of their pathways into care; (2) psychosocial insights into the behavioural domain of HIV testing; and (3) better appreciation of population factors associated with heterogeneity and concomitant inequities. By considering these three aspects of HIV testing in parallel, it is possible to identify gaps, limitations and opportunities in future HIV testing-related interventions. Moreover, it is possible to explore and map how diverse interventions may work together having additive effects. Only a holistic and dynamic framework that captures the increasing complexity of HIV testing is fit for purpose to deliver the maximum public health benefit of HIV testing.

Mixed-methods study in England and Northern Ireland to understand young men who have sex with men's knowledge and attitudes towards human papillomavirus vaccination

OBJECTIVES

Men who have sex with men (MSM) are at greater risk for human papillomavirus (HPV)-associated cancers. Since 2016, MSM have been offered the HPV vaccination, which is most effective when received prior to sexual debut, at genitourinary medicine clinics in the UK. In September 2019, the national HPV vaccination programme will be extended to boys. This study aimed to understand young MSM's (YMSM) knowledge and attitudes towards HPV vaccination.

DESIGN

Questionnaires assessed YMSM demographics, sexual behaviour, culture, knowledge and attitudes towards HPV vaccination and stage of vaccine decision-making using the precaution adoption process model. Focus groups explored sexual health information sources, attitudes, barriers and facilitators to vaccination and strategies to support vaccination uptake. Questionnaire data were analysed using descriptive statistics and focus group data were analysed thematically.

SETTING

Questionnaires were completed online or on paper. Focus groups were conducted within Lesbian Gay Bisexual Transgender Queer organisational settings and a university student's union in England and Northern Ireland.

PARTICIPANTS

Seventeen YMSM (M=20.5 years) participated in four focus groups and 51 (M=21.1 years) completed questionnaires.

RESULTS

Over half of YMSM were aware of HPV (54.9%), yet few (21.6%) had previously discussed vaccination with a healthcare professional (HCP). Thematic analyses found YMSM were willing to receive the HPV vaccine. Vaccination programmes requiring YMSM to request the vaccine, particularly prior to sexual orientation disclosure to family and friends, were viewed as unfeasible. Educational campaigns explaining vaccine benefits were indicated as a way to encourage uptake.

CONCLUSIONS

This study suggests that to effectively implement HPV vaccination for YMSM, this population requires clearer information and greater discussion with their HCP. In support of the decision made by the Joint Committee on Vaccination and Immunisation, universal vaccination is the most feasible and equitable option. However, the absence of a catch-up programme will leave a significant number of YMSM at risk of HPV infection.

Computer-Mediated Communication to Facilitate Synchronous Online Focus Group Discussions: Feasibility Study for Qualitative HIV Research Among Transgender Women Across the United States

Background

Novel, technology-based methods are rapidly increasing in popularity across multiple facets of quantitative research. Qualitative research, however, has been slower to integrate technology into research methodology. One method, computer-mediated communication (CMC), has been utilized to a limited extent for focus group discussions.

Objective

This study aimed to assess feasibility of an online video conferencing system to further adapt CMC to facilitate synchronous focus group discussions among transgender women living in six cities in eastern and southern United States.

Methods

Between August 2017 and January 2018, focus group discussions with adult transgender women were conducted in English and Spanish by research teams based in Boston, MA, and Baltimore, MD. Participants were sampled from six cities: Baltimore, MD; Boston, MA; New York, NY; Washington, DC; Atlanta, GA; and Miami, FL. This was formative research to inform a technology-enhanced cohort study to assess HIV acquisition among transgender women. This analysis focused on the methodologic use of CMC focus groups conducted synchronously using online software that enabled video or phone discussion. Findings were based on qualitative observations of attendance and study team debriefing on topics of individual, social, technical, and logistical challenges encountered.

Results

A total of 41 transgender women from all six cities participated in seven online focus group discussions—five English and two Spanish. There was equal racial distribution of black/African American (14/41, 34%) and white (14/41, 34%) attendees, with 29% (12/41) identifying as Hispanic/Latina ethnicity. Overall, 29 of 70 (41%) eligible and scheduled transgender women failed to attend the focus group discussions. The most common reason for nonattendance was forgetting or having a scheduling conflict (16/29, 55%). A total of 14% (4/29) reported technical challenges associated with accessing the CMC focus group discussion. CMC focus group discussions were found to facilitate geographic diversity; allow participants to control anonymity and privacy (eg, use of pseudonyms and option to use video); ease scheduling by eliminating challenges related to travel to a data collection site; and offer flexibility to join via a variety of devices. Challenges encountered were related to overlapping conversations; variable audio quality in cases where Internet or cellular connection was poor; and distribution of incentives (eg, cash versus gift cards). As with all focus group discussions, establishment of ground rules and employing both a skilled facilitator and a notetaker who could troubleshoot technology issues were critical to the success of CMC focus group discussions.

Conclusions

Synchronous CMC focus group discussions provide a secure opportunity to convene participants across geographic space with minimal time burden and without losing the standardized approach that is expected of focus group discussions. This method may provide an optimal alternative to engaging hard-to-reach participants in focus group discussions. Participants with limited technological literacy or inconsistent access to a phone and/or cellular data or service, as well as circumstances necessitating immediate cash incentives may, however, require additional support and accommodation when participating in CMC focus group discussions.

The use of social marketing campaigns to increase HIV testing uptake: a systematic review

Social marketing campaigns have been increasingly used in HIV prevention efforts to address barriers to HIV testing. The purpose of this review is to evaluate the social marketing campaigns in the past ten years (2008-2017) that have targeted HIV testing or intent to test as an outcome, and synthesize the results to determine which campaigns work or do not work. The search was conducted using PubMed, Scopus, PsycINFO, EMBASE, and ABI/Inform. The quality assessment tool for quantitative studies developed by the Effective Public Health Practice Project was used to assess study quality. The search generated 373 articles, of which 13 articles met the inclusion criteria. These articles were from 13 distinct campaigns carried out in 9 countries, twelve of which were in high income countries. Sixty-nine percent (n = 9) of the campaigns targeted MSM, gay men, or MSMW, 23% (n = 3) targeted the general population, while 8% (n = 1) focused on African-American women. The study designs for evaluating the campaigns were predominantly cross-sectional, with 4 of the articles combining two or three study designs to evaluate their campaign. Overall, 38% (n = 5) of the campaigns had an increase in HIV testing outcomes, 23% (n = 3) reported no change in HIV testing outcomes, and the remaining 38% (n = 5) of the studies reported mixed outcomes. The results of the quality rating showed that 69% (n = 9) of the papers had weak global ratings, while 31% (n = 4) had moderate rating. None of the articles had a strong rating. This review displayed that social marketing campaigns intended to increase HIV testing uptake were effective in some context. Social marketing practitioners will need to come up with a standardized way of communicating the results of campaign exposure and impact so as to enhance comparison among the multitude of campaigns.

Strategies to Increase HIV Testing Among MSM: A Synthesis of the Literature

More than 30 years into the HIV epidemic, men who have sex with men (MSM) continue to be disproportionately impacted. It is estimated that worldwide nearly half of MSM infected with HIV are unaware of their status, making HIV testing along with early linkage to care crucial to HIV prevention efforts. However, there remain significant barriers to HIV testing among MSM, due largely to complex issues of layered stigma that deter MSM from accessing traditional, clinic-based testing. We conducted a review and synthesis of the literature on strategies to increase uptake of HIV testing among MSM. We found that social network-based strategies, community-based testing, HIV self-testing, and modifications to the traditional clinic-based model can effectively reach a subset of MSM, but success was often context-specific and there are significant gaps in evidence. We provide recommendations for increasing HIV testing rates and status awareness among MSM.

National Trends in Sexual Behavior, Substance Use and HIV Testing Among United States Men Who have Sex with Men Recruited Online, 2013 Through 2017

The American Men's Internet Survey (AMIS) is conducted annually with 10,000 men age 15 + who have sex with men (MSM). Modeling was used with 39,863 AMIS surveys from 4 cycles between December 2013 to February 2017 to identify temporal trends in sexual behavior, substance use, and testing behavior (within 12 months preceding interview) stratified by participants' self-reported HIV status. HIV-negative/unknown status MSM had significant increases in condomless anal intercourse (CAI), marijuana use, use of other illicit substances, sexually transmitted infection (STI) diagnoses, and HIV or STI testing (testing only increased among MSM age 25 +). HIV-negative/unknown status MSM had significant decrease in CAI with an HIV-positive or unknown status partner. HIV-positive MSM had significant increases in CAI, methamphetamine use, and STI diagnoses/testing. Although encouraging, the few indicators of improvement in HIV/STI sexual health practices are not consistently seen across sub-groups of MSM and may be counteracted by growing proportions of MSM engaging in CAI and acquiring STIs.

You Wouldn't Sober, You Shouldn't Drunk: A Behavioural Change Approach to Changing Attitudes and Responses to Unwanted Sexual Attention in Pubs and Clubs

Aims

The objective was to evaluate a campaign designed to influence social norms and re-establish boundaries around the issue of unwanted sexual attention in pubs and clubs. In particular, the campaign aimed to raise awareness, and reduce the acceptability, of unwanted sexual attention when drunk.

Methods

A before-after-with-control group study design was used to evaluate campaign effectiveness. The data was further segmented to explore gender differences and between individuals who reported enjoying going out to get drunk and those who did not.

Results

The experimental group with campaign recall demonstrated a significant change in their attitudes to harmful drinking behaviours and unwanted sexual attention compared to the control group. A number of gender differences as well as drink-enjoyment-related differences pre- and post-campaign were observed. Female respondents who were able to recall the campaign demonstrated a significantly lower tolerance of unwanted sexual attention than those who were unable to recall it in either the experimental or control regions. The campaign had limited impact on people who enjoy drunken night outs (DNOs). However, those who do not enjoy DNOs demonstrated significantly higher negative attitudes towards harmful drinking post-campaign recall.

Conclusion

The campaign was effective in shifting attitudes towards unwanted sexual attention and harmful drinking behaviour. This was particularly observed among female respondents and those who do not enjoy DNOs.

Short summary

Drinkaware's 'You Wouldn't Sober, You Shouldn't Drunk' behavioural change campaign targets young adults living in North-West England participating in 'drunken nights out'. The experimental group with campaign recall demonstrated a significant change in their attitudes to harmful drinking behaviours and unwanted sexual attention compared to the control group.

Online interventions to address HIV and other sexually transmitted and blood-borne infections among young gay, bisexual and other men who have sex with men: a systematic review

Introduction

Globally, young gay, bisexual and other men who have sex with men (gbMSM) continue to experience disproportionately high rates of HIV and other sexually transmitted and blood‐borne infections (STBBIs). As such, there are strong public health imperatives to evaluate innovative prevention, treatment and care interventions, including online interventions. This study reviewed and assessed the status of published research (e.g. effectiveness; acceptability; differential effects across subgroups) involving online interventions that address HIV/STBBIs among young gbMSM.

Methods

We searched Medline, Embase, PsycINFO, CINAHL, and Google Scholar to identify relevant English‐language publications from inception to November 2016. Studies that assessed an online intervention regarding the prevention, care, or treatment of HIV/STBBIs were included. Studies with <50% gbMSM or with a mean age ≥30 years were excluded.

Results

Of the 3465 articles screened, 17 studies met inclusion criteria. Sixteen studies assessed interventions at the “proof‐of‐concept” phase, while one study assessed an intervention in the dissemination phase. All of the studies focused on behavioural or knowledge outcomes at the individual level (e.g. condom use, testing behaviour), and all but one reported a statistically significant effect on ≥1 primary outcomes. Twelve studies described theory‐based interventions. Twelve were conducted in the United States, with study samples focusing mainly on White, African‐American and/or Latino populations; the remaining were conducted in Hong Kong, Peru, China, and Thailand. Thirteen studies included gay and bisexual men; four studies did not assess sexual identity. Two studies reported including both HIV+ and HIV− participants, and all but one study included one or more measure of socio‐economic status. Few studies reported on the differential intervention effects by socio‐economic status, sexual identity, race or serostatus.

Conclusion

While online interventions show promise at addressing HIV/STBBI among young gbMSM, to date, little emphasis has been placed on assessing: (i) potential differential effects of interventions across subgroups of young gbMSM; (ii) effectiveness studies of interventions in the dissemination phase; and (iii) on some “key” populations of young gbMSM (e.g. those who are: transgender, from low‐income settings and/or HIV positive). Future research that unpacks the potentially distinctive experiences of particular subgroups with “real world” interventions is needed.

Cross-country Association of Press Freedom and LGBT freedom with prevalence of persons living with HIV: implication for global strategy against HIV/AIDS

BACKGROUND

Human behaviors are affected by attitudes and beliefs, which in turn are shaped by higher-level values to which we have ascribed. In this study, we explore the relationship between two higher-level values, press freedom and LGBT freedom, and HIV infection with national data at the population level.

METHODS

Data were the number of persons living with HIV (PLWH, n = 35,468,911) for 148 countries during 2011-15, press freedom index (PFI) determined by the Reporters Without Borders, and LGBT freedom index (LGBT-FI) based on laws regulating same-sex relationships and expression. PLWH prevalence (1/1000), PFI and LGBT-FI were mapped first. Multiple regression was thus used to associate the logarithm of PLWH prevalence with PFI, LGBT-FI and PFI × LGBT-FI interaction, controlling for per capita GDP and weighted by population size.

RESULTS

Global prevalence of PLWH during 2011-15 was 0.51 per 1000 population. The prevalence showed a geographic pattern moving from high at the south and west ends of the world map to low at the north and east. Both PFI and LGBT-FI were positively associated with PLWH prevalence with a negative interaction between the two.

CONCLUSIONS

More people are infected with HIV in countries with higher press freedom and higher LGBT freedom. Furthermore, press freedom can attenuate the positive association between levels of LGBT freedom and risk of HIV infection. This study demonstrated the urgency for and provided data supporting further research to investigate potential cultural and socioecological mechanisms underpinning the complex relationship among press freedom, LGBT freedom and HIV infection, with data collected at the individual level.

Patterns of HIV testing practices among young gay and bisexual men living in Scotland: a qualitative study

Background

Increasing overall rates, and frequency, of HIV testing in populations at risk is a key public health objective and a critical dimension of HIV prevention efforts. In the UK, men who have sex with men (MSM) remain one of the communities most at risk of HIV and, within this, young gay men are a key risk group. Understanding HIV testing practices is important in the development of interventions to promote testing among young gay and bisexual men.

Methods

Qualitative interviews were conducted with thirty young gay and bisexual men (aged 18–29) in Scotland. Thematic analysis of men’s accounts of their approach to HIV testing identified three overarching patterns of testing: ‘habitual’, ‘reactive’ and ‘ad hoc’.

Results

This qualitative study, the first to explore patterns of HIV testing practices among young gay and bisexual men in the UK, contributes novel findings around the role of social support and ‘community’ in shaping young men’s approaches to HIV testing. The findings suggest that social support can play an important role in encouraging and facilitating HIV testing among young gay men, however, social norms of non-testing also have the potential to act as a barrier to development of a regular routine. Men with habitual testing practices framed HIV testing as both a personal and ‘community’ responsibility, and more effective than testing in response to risk events or emergent symptoms. Men who reported reactive testing practices described testing for HIV primarily in response to perceived exposure to sexual risk, along with ‘transitional moments’ such as starting, ending or changes to a relationship. Among young men who reported testing on an ad hoc basis, inconvenience and disruptions to HIV testing practices, particularly where men lacked social support, acted as a barrier to developing a routine of regular testing.

Conclusions

Our findings suggest that interventions which seek to increase rates of HIV testing and testing frequency among young gay and bisexual men should include a specific focus on promoting and supporting positive testing practices within young men’s friendship groups and wider gay communities.

HIV Testing Behavior and Social Network Characteristics and Functions Among Young Men Who have Sex with Men (YMSM) in Metropolitan Detroit

HIV testing promotion is a critical HIV prevention strategy, especially among at-risk groups such as young men who have sex with men (YMSM). Based on a web survey of 194 YMSM (18-24), we examine the association of social network characteristics and functions, and of individual-level characteristics, with three HIV testing behaviors (ever, repeat, and recent testing). Network homophily was associated with recent testing in multivariable models. The network function of information acquisition was associated with ever testing and repeat testing. Perceived stigma regarding HIV-related help-seeking was negatively related to recent testing. Individual characteristics were associated with testing outcomes in all models; age, perceived behavioral control, and positive attitudes had the greatest influence. Individual characteristics had a stronger association with ever testing and repeat testing than network characteristics and functions; however, this relationship was reversed for recent testing. Findings support the value of multi-level and network-focused interventions for promoting HIV testing among YMSM.

Concordance of Demographic Characteristics, Sexual Behaviors, and Relationship Attributes Among Sex Dyads of Black and White Men Who Have Sex with Men

Differences in individual behaviors have failed to explain racial disparities between Black and White men who have sex with men (MSM). However, reporting of behaviors and partner characteristics are assumed to be non-differentially reported by race. From 314 participants, this study used the two-sided data-where sexual partners provide information on each other and their relationship-of 127 dyads of Black and White MSM from Atlanta, GA, to assess the reliability of partner-reported demographic characteristics and the concordance of sexual behaviors and partnership attributes by race. We compared proportions of concordance by race using a modified kappa (K m) to assess chance-corrected agreement. The median difference in age between self- and partner-reports was 0 (0-1) years. Compared to self-reports, 97 % of the partners of Black participants and 96 % of the partners of White participants correctly classified their race. We observed poor agreement on pre-sexual discussion (K m = 0.18) and being in an ongoing relationship (K m = 0.13), with no differences by race (p = 0.11). Although not statistically significant, Black MSM dyads had lower levels of concordance for unprotected anal intercourse in the previous 12 months (68 %) compared to White dyads (90 %), with fair agreement among Black dyads (K m = 0.26). Measures of partner-reported age and race are likely accurate; however, certain self-reported sexual behaviors and partnership attributes may be unreliable and differentially reported by race. Our findings highlight the need to assess the validity of measures used to estimate HIV transmission and inform racial disparities research.

Findings from within-subjects comparisons of drug use and sexual risk behaviour in men who have sex with men in England

Epidemiological evidence for the encounter-level association between sexualised drug use and unprotected anal intercourse in men who have sex with men is unclear and has not examined men who have sex with men in England. To estimate this association, we compared dyadic sexual encounters within respondents. We used encounter-level data from a longitudinal online survey of men who have sex with men living in England and multilevel models to test univariate and multivariate associations between any respondent or partner drug use, specific respondent drug use, additional situational characteristics and unprotected anal intercourse. Based on 6742 encounters from 2142 men who have sex with men, respondent drug use and respondent use of certain specific drugs were associated with increased unprotected anal intercourse odds. In univariate models, partner drug use was associated with increased unprotected anal intercourse odds, but in multivariate models, only non-specific knowledge of partner drug use was associated with the same. Encounters with non-regular-and-steady partners or that were not HIV-seroconcordant were associated with decreased unprotected anal intercourse odds. This is the first within-subjects comparison of drug use and unprotected anal intercourse conducted on a sample from England, and the largest of its kind. Findings are consistent with other studies, though associations between drug use and unprotected anal intercourse are shaped by social contexts that may change over time.

Social media interventions to prevent HIV: A review of interventions and methodological considerations

Persistent new HIV infections and risky behaviors underscore the need for enhanced HIV prevention. Social media interventions may promote safe sexual behaviors, increase HIV testing uptake, and promote safe injection behaviors. This review discusses how social media interventions tap into the wisdom of crowds through crowdsourcing, build peer-mentored communities, and deliver interventions through social networks. Social media HIV prevention interventions are constrained by ethical issues, low social media usage among some key populations, and implementation issues. Comprehensive measurement of social media interventions to prevent HIV is necessary, but requires further development of metrics.

Nested Event-Level Case-Control Study of Drug Use and Sexual Outcomes in Multipartner Encounters Reported by Men Who Have Sex with Men

Previous event-level analyses have often, but not always, found significant associations between drug use and sexual risk behaviour in men who have sex with men (MSM), but these analyses have rarely considered either multipartner encounters specifically, or other sexual outcomes such as pleasure and control. Using data from an internet-based longitudinal survey of MSM, we tested the association between drug use by respondent and by partners and unprotected anal intercourse (UAI), pleasure and control over sexual activity. Overall respondent substance use was significantly associated with increased odds of UAI, though not with pleasure or control. Respondent use of crystal methamphetamine was significantly associated with both increased odds of UAI and decreased odds of control over sexual activity. This analysis agrees with previous studies of dyadic encounters, and specifically suggests that the association between crystal methamphetamine and sexual risk behaviour may be mediated by loss of control.

Drug use moderates associations between location of sex and unprotected anal intercourse in men who have sex with men: nested cross-sectional study of dyadic encounters with new partners

OBJECTIVES

This nested cross-sectional study of dyadic sexual encounters with new male partners reported by men living in England who have sex with men tested moderation between drug use and location of sex in associations with unprotected anal intercourse (UAI).

METHODS

Data were drawn from two waves of a longitudinal monthly internet survey of men living in England who have sex with men conducted in 2011. Using generalised estimating equations and logit link, we tested the relationship with UAI of any respondent drug use before sex, specific respondent drug use before sex, location of sex (distinguishing private, sex-on-premises venue and cruising locations) and location-drug use interactions.

RESULTS

Any respondent drug use (OR 1.57, 95% CI 1.31 to 1.88) was associated with increased odds of UAI. Relative to encounters in private locations, encounters in sex-on-premises venues (0.69, 95% CI 0.52 to 0.91), but not cruising locations, were associated with decreased odds of UAI. Any respondent drug use, respondent use of poppers and respondent use of alcohol were each associated with increased UAI in sex-on-premises venues.

DISCUSSION

This analysis presents evidence of moderation between drug use and location of sex in associations with UAI. Though this analysis used a large sample, it relied on community-recruited respondents. Our findings may reflect either 'totalising' effects of drug use across venues or site-specific use of drugs as a mechanism for cognitive escape. Additional qualitative research is necessary to understand these findings in context.
