The Mpumalanga Men's Study (MPMS): results of a baseline biological and behavioral HIV surveillance survey in two MSM communities in South Africa

Sexual behaviours and risk with women in MSM in sub-Saharan Africa

In sub-Saharan Africa (SSA), MSM - a high HIV prevalence group - experience strong social stigma and pressure to have female partners. Accordingly, they could constitute a bridging group for HIV transmission to cisgender women. We developed a multilevel summary of MSM sexual behaviors and risk with women in various SSA regions. Following PRISMA guidelines, we conducted a mixed-method systematic review of data of sex with women in MSM in SSA. We performed meta-analyses on quantitative data (i.e. percent of recent sex and condomless sex with women) for each SSA region (when proportions reported in ≥4 studies). Pooled proportions were calculated using random-effects models. Qualitative data were analyzed using the three-step thematic synthesis methodology. The pooled proportion of MSM who had sex with women was 58% (33-83%) in East Africa (in the previous 3 months), and 27% (13-48%) in Southern Africa and 50% (95% CI 39-62%) in West Africa (in the previous 6 months); 23% (16-32%) of MSM in West Africa had condomless sex with a woman (during the most recent encounter). Approximately one quarter of MSM had recent multiple female partners. MSM reported having sex with women because of heteronormative pressure, erotic/romantic attraction, or financial needs leading to transactional sex. MSM may act as a bridging population to women in SSA, as they commonly practice sex with women and risky sexual behaviors with them. HIV programmes and community-based support for MSM should be adapted to this population to reduce this risk.

Factors Associated with Having both Male and Female Recent Sexual Partnerships Among Men Who Have Sex with Men in Harare and Bulawayo, Zimbabwe

To better understand male and female sexual partnerships among men who have sex with men (MSM), we used data from a 2019 biobehavioral survey among MSM in Harare and Bulawayo, Zimbabwe to conduct bivariate analyses and multivariable logistic regression to determine whether sociodemographic characteristics and HIV-related factors were associated with having both male and female sexual partnerships within the last 6 months. Of included MSM (N = 1143), 31% reported both male and female partnerships in the last 6 months. Being married/cohabiting (adjusted odds ratio (aOR) = 8.58, 95% confidence interval (CI) = 4.92-14.95) or separated/divorced/widowed (aOR = 1.96, 95% CI = 1.24-3.08) vs. being single, and hazardous alcohol consumption (aOR = 1.58, 95% CI 1.19-2.09) were associated with higher odds of having both male and female recent partnerships. Being aged 35 + vs. 18-24 (aOR = 0.50, 95% CI = 0.31-0.81), condomless receptive anal intercourse at last sex with the main male partner (aOR = 0.43, 95% CI = 0.26-0.74), and positive HIV status (aOR = 0.46, 95% CI = 0.31-0.67) were associated with lower odds of recent male and female partnerships. MSM in Harare who reported harassment/abuse (aOR = 3.16, 95% CI = 1.72-5.79) had higher odds of both male and female partnerships than MSM in Bulawayo reporting harassment/abuse. The prevalence of both male and female recent partnerships (31%) was lower among MSM in this survey than in other biobehavioral surveys of MSM in sub-Saharan Africa. Findings suggest that MSM with recent male and female partnerships compared to MSM with only male recent partners have lower odds of positive HIV status and participate in behaviors that lower HIV risk; however, the direction of these relationships cannot be determined due to the cross-sectional nature of the data. The findings also suggest a possible connection between experiences of stigma of MSM behavior and not having both male and female partnerships that warrants further exploration. Accessible, stigma-free HIV testing and education programming that considers the potential overlap between the MSM and general populations via both male and female partnerships and the associated behaviors could be a key component of HIV elimination in Zimbabwe.

Developing the Speaking Out and Allying Relationships Intervention on Videoconference for HIV-Positive GBMSM in Eastern Cape, South Africa

In South Africa, HIV prevalence for gay, bisexual, and men who have sex with men (GBMSM) is as high as 49.5%, yet only 25.7% are taking treatment, resulting in transmission risk between partners and the need for dyadic interventions for men in relationships. Through our preliminary research, we identified the evidence-based intervention Healthy Relationships (HR)-an HIV risk assessment and status disclosure intervention for those in relationships-to be tailored into videoconference format for partnered HIV-positive GBMSM in South Africa. The HR adaptation, called SOAR (Speaking Out & Allying Relationships), applied a human-centered design approach. In-depth interviews were conducted with HIV-positive GBMSM (N = 15) to refine intervention preferences with results used to establish a beta SOAR. A trained interventionist conducted SOAR functionality (n = 6) and usability (n = 7) tests with separate invited groups composed of the original participants interviewed. Field logs, focus group discussions, and a study-specific preference survey were administered. Thematic analysis and descriptive statistics were completed with a convergent analytical approach used to understand usability. Overall experience of GBMSM in SOAR was good (69%) or excellent (31%). More than half of the participants (61%) rated using videoconferencing for SOAR as good, with 38% rating it as fair. All participants stated that SOAR was understandable and satisfactory with willingness to recommend it to other GBMSM. This adaptation approach was effective, and the resultant SOAR intervention has the potential to improve individual coping and HIV communication skills with partners to engage with biomedical prevention and in turn support GBMSM couples.

HIV prevalence among men who have sex with men, transgender women and cisgender male sex workers in sub-Saharan Africa: a systematic review and meta-analysis

INTRODUCTION

Developing effective targets, policies and services for key populations requires estimations of population sizes and HIV prevalence across countries and regions. We estimated the relative and absolute HIV prevalence among men who have sex with men (MSM), transgender women and men, and male and transgender sex workers (MSW and TGSW) in sub-Saharan African countries using peer-reviewed literature.

METHODS

We performed a systematic review of peer-reviewed studies assessing HIV prevalence in MSM, transgender women and men, MSW and TGSW in sub-Saharan Africa between 2010 and 2021, following PRISMA guidelines. We searched Embase, Medline Epub, Africa Index Medicus, Africa Journal Online, Web of Science and Google Scholar. We calculated HIV prevalence ratios (PRs) between the study prevalence, and the geospatial-, sex, time and age-matched general population prevalence. We extrapolated results for MSM and transgender women to estimate HIV prevalence and the number living with HIV for each country in sub-Saharan Africa using pooled review results, and regression approximations for countries with no peer-reviewed data.

RESULTS AND DISCUSSION

We found 44 articles assessing HIV prevalence in MSM, 10 in transgender women, five in MSW and zero in transgender men and TGSW. Prevalence among MSM and transgender women was significantly higher compared to the general population: PRs of 11.3 [CI: 9.9-12.9] for MSM and 8.1 [CI: 6.9-9.6] for transgender women in Western and Central Africa, and, respectively, 1.9 [CI: 1.7-2.0] and 2.1 [CI: 1.9-2.4] in Eastern and Southern Africa. Prevalence among MSW was significantly higher in both Nigeria (PR: 12.4 [CI: 7.3-21.0]) and Kenya (PR: 8.6 [CI: 4.6-15.6]). Extrapolating our findings for MSM and transgender women resulted in an estimated HIV prevalence of 15% or higher for about 60% of all sub-Saharan African countries for MSM, and for all but two countries for transgender women.

CONCLUSIONS

HIV prevalence among MSM and transgender women throughout sub-Saharan Africa is alarmingly high. This high prevalence, coupled with the specific risks and vulnerabilities faced by these populations, highlights the urgent need for risk-group-tailored prevention and treatment interventions across the sub-continent. There is a clear gap in knowledge on HIV prevalence among transgender men, MSW and TGSW in sub-Saharan Africa.

The social and sexual lives of Black sexual minority men 30 years of age and older in South Africa

Background

Black sexual minority men (SMM) ages 30 and older are under-represented in HIV studies in sub-Saharan Africa, despite being at increased risk of HIV infection and contributing to potential onward HIV transmission. To better understand the social and sexual lives of older Black South African SMM, we conducted in-depth interviews with SMM who were > 30 years old.

Methods

From March–September 2016, we recruited a convenience sample of 37 SMM ages 30 and older by partnering with an LGBTQ+ organization in Tshwane, Pretoria. Men were interviewed about various aspects of their lives, including their sexual orientation, social connectedness, experiences with stigma and perspectives on participating in research.

Results

Participants described their experiences with their sexual identities, cultural and social implications of disclosure, and their perspective on South Africa’s political perspectives on the LGBTQ+ community. Men described how these experiences influence their trust in research and comfort participating in studies.

Conclusions

Inferences drawn from these findings provide direction on how to improve middle-aged SMM’s representation in research, such as recruiting a higher proportion of older and middle-aged SMM to serve as seed participants and building stronger community partnerships to disseminate study findings to settings where data collection is conducted.

Impact of genetic polymorphisms related to innate immune response on respiratory syncytial virus infection in children

Respiratory syncytial virus (RSV) causes lower respiratory tract infections and bronchiolitis, mainly affecting children under 2 years of age and immunocompromised patients. Currently, there are no available vaccines or efficient pharmacological treatments against RSV. In recent years, tremendous efforts have been directed to understand the pathological mechanisms of the disease and generate a vaccine against RSV. Although RSV is highly infectious, not all the patients who get infected develop bronchiolitis and severe disease. Through various sequencing studies, single nucleotide polymorphisms (SNPs) have been discovered in diverse receptors, cytokines, and transcriptional regulators with crucial role in the activation of the innate immune response, which is implicated in the susceptibility to develop or protect from severe forms of the infection. In this review, we highlighted how variations in the key genes affect the development of innate immune response against RSV. This data would provide crucial information about the mechanisms of viral infection, and in the future, could help in generation of new strategies for vaccine development or generation of the pharmacological treatments.

Correlates of Substance Misuse, Transactional Sex, and Depressive Symptomatology Among Partnered Gay, Bisexual and Other Men Who Have Sex with Men in South Africa and Namibia

Despite having some of the world's highest rates of HIV, there is a lack of knowledge on correlates of transmission risk among gay, bisexual and other men who have sex with men in Southern Africa. There is even less known about the factors that shape HIV risk in male-male couples. Using data from Together Tomorrow, a study of partnered GBMSM in South Africa and Namibia, this study assessed the individual and dyadic correlates of three major HIV risk factors in this population: substance misuse, transactional sex, and depressive symptomatology. Data were collected during November 2016-March 2017 via a quantitative survey conducted with 140 partnered MSM (70 couples) in Windohoek, Keetmanshoop, Walvis Bay, and Swakopmund, Namibia and 300 partnered MSM (150 couples) in Pietermaritzburg and Durban, KwaZulu-Natal, South Africa for a total sample size of 440 partnered MSM (220 couples). Results of multilevel modeling analyses show several significant factors present in partnered GBMSM that differ from studies of single GBMSM, with intimate partner violence being a significant correlate across all three risk factors. Future interventions should consider dyadic approaches and integrate IPV prevention and mitigation efforts to reduce HIV in this population as part of a multisectoral approach. To reduce rates of HIV in partnered GBMSM in Namibia and South Africa multilevel, multisectoral work is needed in policy, social norms change, and relationship-focused dyadic interventions to reduce the social and structural stigma facing male couples.

Men missing from the HIV care continuum in sub-Saharan Africa: a meta-analysis and meta-synthesis

Introduction

Men are missing along the HIV care continuum. However, the estimated proportions of men in sub‐Saharan Africa meeting the UNAIDS 95‐95‐95 goals vary substantially between studies. We sought to estimate proportions of men meeting each of the 95‐95‐95 goals across studies in sub‐Saharan Africa, describe heterogeneity, and summarize qualitative evidence on factors influencing care engagement.

Methods

We systematically searched PubMed and Embase for peer‐reviewed articles published between 1 January 2014 and 16 October 2020. We included studies involving men ≥15 years old, with data from 2009 onward, reporting on at least one 95‐95‐95 goal in sub‐Saharan Africa. We estimated pooled proportions of men meeting these goals using DerSimonion‐Laird random effects models, stratifying by study population (e.g. studies focusing exclusively on men who have sex with men vs. studies that did not), facility setting (healthcare vs. community site), region (eastern/southern Africa vs. western/central Africa), outcome measurement (e.g. threshold for viral load suppression), median year of data collection (before vs. during or after 2017) and quality criteria. Data from qualitative studies exploring barriers to men's HIV care engagement were summarized using meta‐synthesis.

Results and discussion

We screened 14,896 studies and included 129 studies in the meta‐analysis, compiling data over the data collection period. Forty‐seven studies reported data on knowledge of serostatus, 43 studies reported on antiretroviral therapy use and 74 studies reported on viral suppression. Approximately half of men with HIV reported not knowing their status (0.49 [95% CI, 0.41–0.58; range, 0.09–0.97]) or not being on treatment (0.58 [95% CI, 0.51–0.65; range, 0.07–0.97]), while over three‐quarters of men achieved viral suppression on treatment (0.79 [95% CI, 0.77–0.81; range, 0.39–0.97]. Heterogeneity was high, with variation in estimates across study populations, settings and outcomes. The meta‐synthesis of 40 studies identified three primary domains in which men described risks associated with engagement in HIV care: perceived social norms, health system challenges and poverty.

Conclusions

Psychosocial and systems‐level interventions that change men's perceptions of social norms, improve trust in and accessibility of the health system, and address costs of accessing care are needed to better engage men, especially in HIV testing and treatment.

A skills-based sero-status HIV disclosure intervention for sexual minority men in South Africa: A protocol for intervention adaptation and pilot randomized controlled trial (Preprint)

Background

Gay, bisexual, and other men who have sex with men (GBMSM) living with HIV have low antiretroviral treatment adherence in South Africa due to limited skills in managing disclosure and prevention behaviors with sexual and romantic partners. As a result, there is a high HIV transmission risk within HIV-discordant partnerships, but an existing intervention may address these outcomes, if adapted effectively. Healthy Relationships (HR) is a behavioral intervention that was originally delivered in groups and in person over 5 sessions to develop coping skills for managing HIV-related stress and sexually risky situations, enhance decision-making skills for HIV disclosure to partners, and establish and maintain safer sex practices with partners. HR effectively improves prevention behaviors but has yet to be tailored to a non-US context.

Objective

We aim to adapt HR into a new culturally grounded intervention entitled Speaking Out & Allying Relationships for GBMSM and then assess its feasibility in Eastern Cape, South Africa.

Methods

The study will have 2 aims. For aim 1—adaptation—we will use a human-centered design approach. Initial intervention tailoring will involve integrating Undetectable=Untransmittable and pre-exposure prophylaxis education, developing intervention content for a videoconference format, and designing role-plays and movies for skill building based on preliminary data. Afterward, interviews and surveys will be administered to GBMSM to assess intervention preferences, and a focus group will be conducted with health care providers and information technology experts to assess the intervention’s design. Finally, a usability test will be performed to determine functionality and content understanding. Participants will be GBMSM living with HIV (n=15) who are in a relationship and health care providers and information technology (n=7) experts working in HIV care and programming with this population. For aim 2, we will examine the feasibility of the adapted intervention by using a pilot randomized control design. There will be 60 individuals per arm. Feasibility surveys and interviews will be conducted with the intervention arm, and behavioral and biomedical assessments for relationship and treatment adherence outcomes will be collected for both arms. All participants will be GBMSM living with HIV who are in a relationship with an HIV-negative or unknown status partner.

Results

Intervention adaptation began in August 2021. Initial tailoring and the refining of GBMSM intervention preferences were completed in December 2021. Usability and feasibility assessments are due to be completed by March 2022 and February 2024, respectively.

Conclusions

GBMSM need efficacious interventions that tackle partnership dynamics, HIV prevention, and treatment outcomes for antiretroviral treatment adherence and viral suppression in South Africa. Harnessing everyday technology use for social networking (eg, videoconferences), Undetectable=Untransmittable education, and pre-exposure prophylaxis to update an existing intervention for South African GBMSM has the potential to strengthen relationship communication about HIV treatment and prevention and, in turn, improve outcomes.

Factors influencing HIV-risk perception among MSM students at a university in Durban, South Africa

Risk perception is embedded in attitudes and beliefs that determine how one ultimately behaves. In relation to HIV-risk behaviours, risk perception is a key dimension in most health behaviour models used to construct health promotion campaigns. This study aimed to understand HIV-risk perception and associated factors among men who have sex with men (MSM). The qualitative data used in this study came from 15 in-depth interviews with MSM studying at the University of KwaZulu-Natal in Durban, South Africa. The findings show that MSM perceive themselves to be at risk for HIV due to their awareness of the main routes of infection. This perception exists because HIV has affected them through the loss of close family members. With each sexual encounter, risk perception changed based on factors such as the sexual role being assumed (insertive versus receptive), the socio-economic status of the partner, perceived level of discriminatory dating patterns, and the use of preventive measures. High levels of risk perception among the men did not translate into positive attitudes towards condoms as many of them preferred to have unprotected sex with trusted partners. Despite perceiving their risk of HIV infection to be high, MSM continue to engage in multiple sexual partnerships and high partner turnover. However, the men in this study were keen to protect their health; with time, they have developed more positive attitudes towards HIV and they understand that it is possible to protect oneself before and after infection.

Psychosocial characteristics and HIV-related sexual behaviors among cisgender, transgender, and gender non-conforming MSM in China

BACKGROUND

While a growing number of studies focus on men who have sex with men (MSM), they typically ignore the heterogeneity of gender minorities within the MSM population. The recognition of new sub-groups among gender minorities (i.e., transgender and gender non-conforming), who also identify as MSM, play a considerable role in new HIV infections in China. Information on the psychosocial factors and HIV-related sexual behaviors require further consideration to understand the prevalence of HIV infection among MSM within these gender minority sub-groups.

METHODS

From September 2017 to January 2018, MSM without HIV were recruited in Wuhan, Nanchang, and Changsha cities in China. Participants were asked to fill out a structured self-administered questionnaire to assess depression, perceived social support, resilience, identity concealment, and HIV-related risky sexual behaviors.

RESULTS

A total of 715 MSM completed the structured questionnaire, the number of MSM identifying as gender minorities were 63 and accounted for 8.8% of the population. Compared to the cisgender MSM population, transgender MSM were more likely to have a one-night stand/occasional partner (AOR = 3.49, 95% CI =1.02-11.98), to have sex after drug use in the past 6 months (AOR = 2.57, 95%CI =1.05-6.29), and to have reported a significantly lower likelihood of identity concealment (mean difference = - 3.30, 95%CI = -5.86, - 0.74, P = 0.01).

CONCLUSIONS

The findings highlight the significance of providing targeted interventions for different gender minorities within the MSM population. Research is required to further understand the relationship between gender identity, mental health, and HIV-related sexual behaviors.

Reaching a Different Population of MSM in West Africa With the Integration of PrEP Into a Comprehensive Prevention Package (CohMSM-PrEP ANRS 12369-Expertise France)

BACKGROUND

In West Africa, few HIV services target men who have sex with men (MSM). In 2015, the interventional cohort CohMSM started offering a community-based prevention package for MSM. Participants expressed interest in pre-exposure prophylaxis (PrEP) and their eligibility was demonstrated. In 2017, PrEP was added to services already offered as part of a new program, CohMSM-PrEP, which recruited CohMSM participants and new participants. We aimed to determine whether the introduction of PrEP as an additional prevention tool influenced the type of participant signing up for CohMSM-PrEP.

METHODS

CohMSM-PrEP recruited HIV-negative MSM in community-based clinics in Mali, Cote d'Ivoire, Burkina Faso, and Togo. Quarterly follow-up included free clinical examinations, PrEP, HIV/sexually transmitted infection screening, peer education, condoms, and lubricants. Sociobehavioral data were collected every 3 months using face-to-face questionnaires. Our outcome was participant type: new participants vs CohMSM participants. Logistic regression was performed to identify the factors associated with being a new participant.

RESULTS

Of the 524 MSM included in CohMSM-PrEP, 41% were new participants. After adjustment, multivariate analysis showed they were more socioeconomically disadvantaged with financial insecurity, social isolation-including isolation within the MSM community-and riskier sexual practices.

CONCLUSION

The introduction of PrEP as an additional prevention tool and the use of peer-based outreach services over time influenced the type of participant signing up for a community-based HIV prevention cohort in West Africa. Adding these elements to existing interventions in Sub-Saharan Africa could be the key to reaching MSM marginalized from HIV prevention and care programs.

Estimating the contribution of key populations towards HIV transmission in South Africa

INTRODUCTION

In generalized epidemic settings, there is insufficient understanding of how the unmet HIV prevention and treatment needs of key populations (KPs), such as female sex workers (FSWs) and men who have sex with men (MSM), contribute to HIV transmission. In such settings, it is typically assumed that HIV transmission is driven by the general population. We estimated the contribution of commercial sex, sex between men, and other heterosexual partnerships to HIV transmission in South Africa (SA).

METHODS

We developed the "Key-Pop Model"; a dynamic transmission model of HIV among FSWs, their clients, MSM, and the broader population in SA. The model was parameterized and calibrated using demographic, behavioural and epidemiological data from national household surveys and KP surveys. We estimated the contribution of commercial sex, sex between men and sex among heterosexual partnerships of different sub-groups to HIV transmission over 2010 to 2019. We also estimated the efficiency (HIV infections averted per person-year of intervention) and prevented fraction (% IA) over 10-years from scaling-up ART (to 81% coverage) in different sub-populations from 2020.

RESULTS

Sex between FSWs and their paying clients, and between clients with their non-paying partners contributed 6.9% (95% credibility interval 4.5% to 9.3%) and 41.9% (35.1% to 53.2%) of new HIV infections in SA over 2010 to 2019 respectively. Sex between low-risk groups contributed 59.7% (47.6% to 68.5%), sex between men contributed 5.3% (2.3% to 14.1%) and sex between MSM and their female partners contributed 3.7% (1.6% to 9.8%). Going forward, the largest population-level impact on HIV transmission can be achieved from scaling up ART to clients of FSWs (% IA = 18.2% (14.0% to 24.4%) or low-risk individuals (% IA = 20.6% (14.7 to 27.5) over 2020 to 2030), with ART scale-up among KPs being most efficient.

CONCLUSIONS

Clients of FSWs play a fundamental role in HIV transmission in SA. Addressing the HIV prevention and treatment needs of KPs in generalized HIV epidemics is central to a comprehensive HIV response.

Building self-advocacy in HIV care: the use of role-play to examine healthcare access for HIV-positive MSM in rural South Africa

There is high HIV prevalence and low rates of viral suppression for men who have sex with men (MSM) in South Africa, with few MSM-centered interventions to address these outcomes along the HIV treatment cascade. Participatory interventions may support community building among HIV-positive MSM through which they can share approaches of self-advocacy that are contextually grounded. We conducted a pilot study to assess the use of role-plays in influencing social isolation while also updating our understanding of MSM healthcare experiences in Mpumalanga, South Africa. The study was conducted with 21 MSM leaders who were HIV-positive. There were three groups of seven participants each who created and performed role-plays based on their healthcare experiences, with a focus group discussion (FGD) conducted afterward. Audio-recordings were transcribed, translated, and analyzed using a constant comparison approach. We found that MSM described role-play as cathartic and a future HIV care educational tool for other MSM, and that they outlined points of self-advocacy during HIV care in clinics. Our study suggests that future research should utilize role-play so to integrate contextual factors influencing HIV treatment, especially in high HIV prevalence settings.

Increases in HIV status disclosure and sexual communication between South African men who have sex with men and their partners following use of HIV self-testing kits

Availability of HIV self-testing may increase HIV testing frequency among men who have sex with men (MSM). It is unclear, however, if self-testing may impact HIV-related sexual behaviors among MSM, including HIV status disclosure and condom use. We conducted a mixed methods analysis of changes in HIV-related behaviors after HIV self-testing introduction, using data from 110 MSM participating in a feasibility and acceptability study of HIV self-testing in Mpumalanga Province, South Africa. We found increased HIV status disclosure from study participants to sexual partners after HIV self-testing introduction, from 61.8% at baseline to 75.5% at 6-month follow-up (p = 0.04), but decreased condom use with female partners (p = 0.03). Qualitative interviews reveal that some participants used test results to inform condom use. Distribution of self-testing kits can improve mutual disclosure, but should be accompanied by information stressing that the tests may not detect early HIV infections or other sexually transmitted infections.

Power relations in sexual agreements among male couples in Southern Africa

Sexual agreements between same-sex practising men facilitate communication about health promotion activities, including HIV prevention. In African contexts, male couples negotiate their sexual agreements in relation to rigid cultural prescriptions about male power and privilege, intense hostility towards same-sex sexualities and persistent heterogendered socio-cultural norms. Yet the impact of such norms on relationship practices and HIV risk among male couples remains inadequately explored. This qualitative study examined the role of gendered power disparities in establishing sexual agreements among male couples in two Southern African contexts. Eighteen male couples completed in-depth interviews focused on relationship practices, including sexual agreements. The research employed critical social theory to analyse power relations and socio-cultural norms shaping male couples' explicit and implicit sexual agreements, with a focus on implications for HIV risk. The findings outline different types of and motivations for sexual agreements among male couples, including qualified non-monogamy with female partners only. The study illustrates how Southern African male-male sexual practices remain embedded in a cultural context favouring the replication of heteronormative sexual behaviours and relationship practices. These heterogendered norms impact negatively on the process of establishing explicit, mutually agreed-upon sexual agreements, and thus place male couples at increased risk for HIV.

Intimate Partner Violence in Transgender Populations: Systematic Review and Meta-analysis of Prevalence and Correlates

Background: Transgender individuals experience unique vulnerabilities to intimate partner violence (IPV) and may experience a disproportionate IPV burden compared with cisgender (nontransgender) individuals.Objectives: To systematically review the quantitative literature on prevalence and correlates of IPV in transgender populations.Search Methods: Authors searched research databases (PubMed, CINAHL), gray literature (Google), journal tables of contents, and conference abstracts, and consulted experts in the field. Authors were contacted with data requests in cases in which transgender participants were enrolled in a study, but no disaggregated statistics were provided for this population.Selection Criteria: We included all quantitative literature published before July 2019 on prevalence and correlates of IPV victimization, perpetration, or service utilization in transgender populations. There were no restrictions by sample size, year, or location.Data Collection and Analysis: Two independent reviewers conducted screening. One reviewer conducted extraction by using a structured database, and a second reviewer checked for mistakes or omissions. We used random-effects meta-analyses to calculate relative risks (RRs) comparing the prevalence of IPV in transgender individuals and cisgender individuals in studies in which both transgender and cisgender individuals were enrolled. We also used meta-analysis to compare IPV prevalence in assigned-female-sex-at-birth and assigned-male-sex-at-birth transgender individuals and to compare physical IPV prevalence between nonbinary and binary transgender individuals in studies that enrolled both groups.Main Results: We identified 85 articles from 74 unique data sets (n_total = 49 966 transgender participants). Across studies reporting it, the median lifetime prevalence of physical IPV was 37.5%, lifetime sexual IPV was 25.0%, past-year physical IPV was 16.7%, and past-year sexual IPV was 10.8% among transgender individuals. Compared with cisgender individuals, transgender individuals were 1.7 times more likely to experience any IPV (RR = 1.66; 95% confidence interval [CI] = 1.36, 2.03), 2.2 times more likely to experience physical IPV (RR = 2.19; 95% CI = 1.66, 2.88), and 2.5 times more likely to experience sexual IPV (RR = 2.46; 95% CI = 1.64, 3.69). Disparities persisted when comparing to cisgender women specifically. There was no significant difference in any IPV, physical IPV, or sexual IPV prevalence between assigned-female-sex-at-birth and assigned-male-sex-at-birth individuals, nor in physical IPV prevalence between binary- and nonbinary-identified transgender individuals. IPV victimization was associated with sexual risk, substance use, and mental health burden in transgender populations.Authors' Conclusions: Transgender individuals experience a dramatically higher prevalence of IPV victimization compared with cisgender individuals, regardless of sex assigned at birth. IPV prevalence estimates are comparably high for assigned-male-sex-at-birth and assigned-female-sex-at-birth transgender individuals, and for binary and nonbinary transgender individuals, though more research is needed.Public Health Implications: Evidence-based interventions are urgently needed to prevent and address IPV in this high-risk population with unique needs. Lack of legal protections against discrimination in employment, housing, and social services likely foster vulnerability to IPV. Transgender individuals should be explicitly included in US Preventive Services Task Force recommendations promoting IPV screening in primary care settings. Interventions at the policy level as well as the interpersonal and individual level are urgently needed to address epidemic levels of IPV in this marginalized, high-risk population.

HIV testing, care and viral suppression among men who have sex with men and transgender individuals in Johannesburg, South Africa

INTRODUCTION

Men who have sex with men and transgender individuals (MSM/TG) carry a disproportionately high burden of HIV, including in South Africa. However, there are few empirical population-representative estimates of viral suppression and the HIV care cascade including HIV testing among this population, nor of factors associated with these outcomes.

METHODS

We conducted a respondent driven sampling (RDS) survey among 301 MSM/TG in Johannesburg in 2017. Participants gave blood samples for HIV testing and viral load. Participants self-completed a survey including sociodemographics, HIV testing history, and engagement in care. We calculated RDS-II weighted estimates of the percentage of HIV-negative MSM/TG reporting HIV testing in the previous 6 months, their testing experience and preferences. Among those HIV-positive, we estimated the percentage status-aware, on ART, and virally suppressed (<50 viral copies/ml plasma). We conducted RDS-weighted robust Poisson regression to obtain weighted prevalence ratios of factors associated with 1) HIV testing among those HIV-negative; and 2) viral suppression among those HIV-positive.

RESULTS

There were 118/300 HIV-positive MSM/TG, (37.5%). Of the HIV-negative MSM/TG, 61.5% reported that they had tested for HIV in the previous 6 months, which was associated with selling sex to men (Prevalence Ratio = 1.67, 95% CI 1.36-2.05). There were 76/118 HIV-positive MSM/TG (56.5%) who reported having previously tested positive for HIV and 39/118 (30.0%) who reported current ART. There were 58/118 HIV-positive MSM/TG with viral loads <50 copies/ml plasma (46.9%). Viral suppression was associated with older age (adjusted PR = 1.03, 95% CI 1.00-1.06 for each year), neighbourhood, and having bought sex from men (adjusted PR = 1.53, 95% CI 1.12-2.08).

CONCLUSIONS

HIV prevalence was very high. Viral suppression among those HIV-positive was similar to the general male population in South Africa, but remains far short of national and international targets. A majority of HIV-negative MSM/TG had HIV tested in the previous 6 months, though there is room for improvement.

HIV Prevention Interventions for Adolescents

PURPOSE OF REVIEW

The goal of this paper is to review recent data on biomedical, behavioral, and structural HIV prevention interventions for adolescents and young adults.

RECENT FINDINGS

While it is accepted that HIV prevention interventions must take an integrated approach to achieve maximum effectiveness, to date, there have been limited, rigorously evaluated combination prevention interventions for adolescents. There are currently a range of effective biomedical, behavioral, and structural approaches that can be integrated into prevention packages to address the prevention needs of adolescents, including oral PrEP, male circumcision, rapid HIV testing, numerous behavioral interventions, and structural interventions such as cash transfers and community mobilization to address gender-based violence. There is still a need for rigorously evaluated, innovative combination prevention packages for adolescents. Prevention approaches must take into account the context of young people's lives and address the multiple levels of influence on their lives including parents, partners, and communities.

Combined Sexual Behavioral Profiles in HIV-Seronegative Men Who have Sex with Men in West Africa (CohMSM ANRS 12324-Expertise France)

Understanding the dynamics of HIV infection in men who have sex with men (MSM) can help improve efficiency in existing prevention strategies. We aimed to identify and describe the sexual behaviors of MSM most at risk of HIV infection in West Africa. HIV-negative MSM were provided a quarterly preventive follow-up package in the community-based cohort CohMSM. They completed face-to-face sociobehavioral questionnaires every 6 months. This sub-study on 520 participants used a baseline, 6-, 12- and 18-month data cluster analysis to categorize two profiles (high risk [HRE] and moderate risk [MRE] of exposure to HIV) based on three risky sexual practices over the previous 6 months. HRE-MSM (61%) were more engaged in receptive practices, had a higher proportion of inconsistent condom use during anal sex, and reported more sexual partners than MRE-MSM (39%). The proportion of HIV seroconversions observed during the first 18 months of follow-up using sexual behavioral profiles (92% are HRE-MSM) was higher than using the three risky sexual practices separately. Factors associated with the HRE-MSM profile were being younger (18-21 years), reporting stigma, and having had no female partner while being attracted only to men. Our findings suggest that in order to identify MSM most at risk of HIV infection, several risky sexual practices need to be evaluated in a combined approach. Prevention programs should pay particular attention to younger MSM, and implement activities addressing questions of MSM identity and stigma in order to reduce the dynamic of HIV infection in Western African MSM.

HIV testing and engagement with the HIV treatment cascade among men who have sex with men in Africa: a systematic review and meta-analysis

BACKGROUND

HIV disproportionately affects gay, bisexual, and other men who have sex with men (MSM) in Africa, where many countries criminalise same-sex behaviour. We assessed changes in the engagement of African MSM with HIV testing and treatment cascade stages over time, and the effect of anti-LGBT legislation and stigma.

METHODS

We systematically searched Embase, Global Health, MEDLINE, Scopus, and Web of Science for peer-reviewed cross-sectional or longitudinal studies recruiting at least ten MSM, published from Jan 1, 1980, to Oct 10, 2018. We extracted or derived estimates of HIV testing, engagement with the HIV treatment cascade, or both among African MSM from published reports. We derived pooled estimates using inverse-variance random-effects models. We used subgroup and meta-regression analysis to assess associations between testing and status awareness outcomes and study and participant characteristics, including the severity of country-level anti-LGBT legislation.

FINDINGS

Our searches identified 75 independent eligible studies that provided estimates for 44 993 MSM across one or more of five testing and treatment cascade outcomes. HIV testing increased significantly over time overall, with pooled proportions of MSM ever tested for HIV of 67·3% (95% CI 62·1-72·3; 44 estimates) and tested in the past 12 months of 50·1% (42·4-57·8, 31 estimates) after 2011, which were 14·8 percentage points and 17·9 percentage points higher than before 2011, respectively. After 2011, ever testing was highest in southern Africa (80·0%), and lowest in northern Africa (34·4%), with the greatest increase in western Africa (from 42·4% to 70·9%). Levels of testing ever, in the past 12 months, and status awareness were statistically significantly lower in countries with the most severe anti-LGBT legislation compared with countries with the least severe legislation (57·4% vs 71·6%, p=0·0056; 35·5% vs 49·3%, p=0·010; 6·7% vs 22·0%, p=0·0050). Few estimates were available for later stages of the treatment cascade. Available data after 2011 suggest that the pooled proportion of MSM HIV-positive aware has remained low (18·5%, 12·5-25·3; 28 estimates), whereas proportions of current antiretroviral therapy (ART) use were 23·7% (15·5-33·0; 13 estimates) among all MSM living with HIV and 60·1% (48·6-71·1; five estimates) among MSM HIV-positive aware of their status. Pooled levels of viral suppression among MSM currently on ART were 75·6% (64·4-85·5; four estimates), but only 24·7% (18·8-31·2; four estimates) among all MSM living with HIV.

INTERPRETATION

Despite improvements in HIV testing among MSM in Africa, HIV status awareness, ART coverage, and viral suppression remain much lower than required to achieve UNAIDS 90-90-90 targets. Further studies are urgently needed to provide more accurate estimates of levels of status awareness, engagement in care, ART coverage, and viral suppression among MSM to inform prevention efforts aimed at improving access to HIV services for MSM. Severe anti-LGBT legislation might be associated with lower HIV testing and status awareness; therefore, further research is needed to assess the effect of such legislation on HIV testing and engagement with the HIV treatment cascade among MSM.

'My Tablets are on Top of the Fridge': The Roles of Relationship Desire and Medical Mistrust in ART Adherence for HIV-Positive MSM and Transgender Women Living in Rural South Africa

Given the high HIV prevalence for men who have sex with men (MSM) and transgender women in South Africa, there is limited understanding of social determinants that influence antiretroviral treatment (ART) adherence. Although universal testing and treatment (UTT) is available, ART adherence remains suboptimal. We conducted focus groups with MSM and transgender women in order to understand factors influencing their ART adherence in Mpumalanga, South Africa. All focus groups were audio-recorded, transcribed and translated for analysis using a constant comparison approach, guided by the concept of Therapeutic Citizenship. We found there is medical mistrust of ART based on differing interpretations of HIV cure that may influence treatment adherence behaviors within social networks, and relationship desire had a significant influence on optimal ART adherence. Our findings suggest that clinics must provide interventions that integrate HIV disclosure and relationship skill-building to support optimal ART adherence for MSM and transgender women under UTT.

Optimal HIV testing strategies for South Africa: a model-based evaluation of population-level impact and cost-effectiveness

Although many African countries have achieved high levels of HIV diagnosis, funding constraints have necessitated greater focus on more efficient testing approaches. We compared the impact and cost-effectiveness of several potential new testing strategies in South Africa, and assessed the prospects of achieving the UNAIDS target of 95% of HIV-positive adults diagnosed by 2030. We developed a mathematical model to evaluate the potential impact of home-based testing, mobile testing, assisted partner notification, testing in schools and workplaces, and testing of female sex workers (FSWs), men who have sex with men (MSM), family planning clinic attenders and partners of pregnant women. In the absence of new testing strategies, the diagnosed fraction is expected to increase from 90.6% in 2020 to 93.8% by 2030. Home-based testing combined with self-testing would have the greatest impact, increasing the fraction diagnosed to 96.5% by 2030, and would be highly cost-effective compared to currently funded HIV interventions, with a cost per life year saved (LYS) of $394. Testing in FSWs and assisted partner notification would be cost-saving; the cost per LYS would also be low in the case of testing MSM ($20/LYS) and self-testing by partners of pregnant women ($130/LYS).

Sexual violence experiences among black gay, bisexual, and other men who have sex with men and transgender women in South African townships: contributing factors and implications for health

This study examined experiences with sexual violence among Black African gay, bisexual, and other men who have sex with men (GBMSM) and transgender women (TGW) in townships surrounding Pretoria, South Africa. Of 81 GBMSM and TGWs interviewed, 17 reported to have experienced sexual violence perpetrated by other men. Qualitative analysis of interviews revealed the social and relational context of these experiences as well as their psychological and health consequences. The described context included single- and multiple-perpetrator attacks in private and public spaces, bias-motivated attacks, and violence from known partners. Several participants reported refusing propositions for sex as a reason for being victimized. HIV-positive individuals were overrepresented among survivors compared to the sample as a whole. Following victimization, participants described feelings of pain, fear, anger and self-blame. The results demonstrate the need for interventions designed to (a) prevent sexual violence against GBMSM and TGW in this population, and (b) reduce the negative psychological and health outcomes of sexual victimization. The discussion also highlights the need to examine more closely the link between experiences of sexual violence and risk for HIV infection.

HIV self-screening distribution preferences and experiences among men who have sex with men in Mpumalanga Province: Informing policy for South Africa

Current research suggests that HIV self-screening (HIVSS) is a feasible and acceptable approach to increase HIV testing among men who have sex with men (MSM). However, few data are available to shape policy around dissemination and implementation. Gaps in knowledge include preferences for distribution of HIVSS kits, potential social harms and benefits of their use, and how much test users would be willing to pay for the kits. The aim was to inform policy recommendations to optimise distribution of HIVSS kits to MSM in South Africa (SA), where there is a high HIV incidence and unmet testing needs. MSM in the high-HIV-prevalence Gert Sibande and Ehlanzeni districts of Mpumalanga Province, SA, were enrolled between October 2015 and May 2017. Participants were provided with their choice of blood or oral fluid HIVSS test kits, receiving 5 kits at enrolment and 4 additional kits at the 3-month follow-up visit. Questionnaires were administered at enrolment, 3 months and 6 months. We analysed participants' reported social benefits and harms, and their preferences for kit distribution and pricing. Among 127 MSM screened and enrolled, 114 responded to follow-up questionnaires regarding distribution preferences, 49.3% preferred to acquire HIVSS kits at a community-based organisation (CBO) and 42.7% at a clinic, with 8% preferring a pharmacy. Participants with higher education preferred CBO sites for distribution; in other respects preferences were similar by demographic characteristics. Reported social benefits were common, including knowing one's status, prevention knowledge gained and improved communication with partners. Despite ubiquitous interest in using the kits, the majority of MSM could not afford to purchase test kits. SA guidelines have integrated HIVSS into HIV and testing policy, but little has been published regarding distribution channels of the kits for MSM and other key populations. There is a partnership between the National Department of Health and CBOs that specialise in key population programming to ensure MSM and other populations with unmet testing needs can access affordable test kits. We observed no social harms, and there were multiple social benefits. Consequently, we recommend immediate free or low-cost distribution of HIVSS kits to MSM through community-based initiatives. Future research should continue to assess optimised linkage to care.

HIV Prevalence and Associated Risk Factors Among Men Who Have Sex With Men in Dar es Salaam, Tanzania

INTRODUCTION

Limited studies and differential risk behaviors among men who have sex with men (MSM) in Africa calls for population-specific studies. We present results from the largest integrated biobehavioral survey among MSM in Africa to inform programming.

METHODS

This was a cross-sectional study using respondent-driven sampling to recruit MSM aged 18 and above. Data on sociodemographic characteristics and HIV-related risks were collected and all participants were tested for HIV, herpes simplex virus type-2 (HSV-2), hepatitis-B virus (HBV), and syphilis RESULTS:: A total of 753 MSM with a mean age of 26.5 years participated in the study and 646 (85.7%) provided blood for biological testing. The prevalence of HIV was 22.3%, HSV-2 40.9%, syphilis 1.1%, and HBV 3.25%. Significant risk factors for HIV were age above 25, having no children [adjusted odds ratio (aOR), 2.4, 95% confidence interval (CI): 1.4 to 4.2], low HIV-risk perception (aOR, 2.6, 95% CI: 1.2 to 5.3), receptive position (aOR, 8.7, 95% CI: 1.2 to 5.3), and not using water-based lubricants (aOR, 2.6, 95% CI: 1.0 to 4.5) during the last anal sex. Also associated with HIV infection was, having sexual relationships with women (aOR, 8.0, 95% CI: 4.1 to 15.6), engaging in group sex (aOR, 3.8, 95% CI: 1.6 to 8.4), HSV-2 seropositivity (aOR, 4.1, 95% CI: 2.6 to 6.5), and history of genital ulcers (aOR, 4.1, 95% CI: 1.1 to 7.2).

CONCLUSIONS

HIV infection and HSV-2 were highly prevalent among MSM. Low perceived HIV risk, practice of risk behaviors, and infection with HSV-2 were significant predictors of HIV infection. Behavioral interventions, HSV-2 suppressive therapies, and pre-exposure prophylaxis are highly needed.

Accuracy of Self-Reported HIV Status Among African Men and Transgender Women Who Have Sex with Men Who were Screened for Participation in a Research Study: HPTN 075

Some HIV-infected individuals in research studies may choose not to disclose knowledge of their HIV status to study staff. We evaluated the accuracy of self-reported HIV status among African men and transgender women who have sex with men and who were screened for a research study. Sixty-seven of 183 HIV-infected participants reported a prior HIV diagnosis. Samples from the remaining 116 participants were tested for antiretroviral (ARV) drugs. Thirty-six of the 116 participants had ARV drugs detected, indicating that they were on antiretroviral treatment; these participants were classified as previously diagnosed based on ARV drug testing. Among participants classified as previously diagnosed, disclosure of a prior HIV diagnosis varied among study sites (p = 0.006) and was more common among those who reported having sex with men only (p = 0.002). ARV drug testing in addition to self-report improves the accuracy for identifying individuals with a prior HIV diagnosis.

Ability to use oral fluid and fingerstick HIV self-testing (HIVST) among South African MSM

BACKGROUND

HIV self-testing (HIVST) may increase HIV testing uptake, facilitating earlier treatment for key populations like MSM who experience barriers accessing clinic-based HIV testing. HIVST usability among African MSM has not been explored.

METHODS

We assessed usability of oral fluid (OF) and fingerstick (FS; blood) HIVST kits during three phases among MSM with differing degrees of HIVST familiarity in Mpumalanga, South Africa. In 2015, 24 HIVST-naïve MSM conducted counselor-observed OF and FS HIVST after brief demonstration. In 2016 and 2017, 45 and 64 MSM with experience using HIVST in a pilot study chose one HIVST to conduct with a counselor-observer present. In addition to written, the latter group had access to video instructions. We assessed frequency of user errors and reported test use ease, changes in error frequency by phase, and covariates associated with correct usage using log-Poisson and Gaussian generalized estimating equations.

RESULTS

Among OF users (n = 57), 15-30% committed errors in each phase; however, observers consistently rated participants as able to test alone. Among FS users (n = 100), observers noted frequent errors, most commonly related to blood collection and delivery. We found suggestive evidence (not reaching statistical significance) that user errors decreased, with 37.5%, to 28.1%, and 18.2% committing errors in phases I, II, and III, respectively (p-value:0.08), however observer concerns remained constant. Ease and confidence using HIVST increased with HIV testing experience. Participants using three HIVST were more likely (RR:1.92, 95% CI:1.32, 2.80) to report ease compared to those without prior HIVST experience. Never testers (RR:0.66, 95% CI:0.44-0.99) reported less ease performing HIVST compared to participants testing in the past six months.

CONCLUSIONS

MSM were able to perform the OF test. Fingerstick test performance was less consistent; however preference for fingerstick was strong and performance may improve with exposure and instructional resources. Continued efforts to provide accessible instructions are paramount.

Biometrics and public health surveillance in criminalised and key populations: policy, ethics, and human rights considerations

Widespread public health surveillance efforts focused on key populations (men who have sex with men, sex workers, people who inject drugs, and others) gather data on population sizes, HIV prevalence, and other information for planning and resource allocation. Biometric identification might improve this data gathering. However, in the context of extensive criminalisation of these populations, the use of biometrics such as fingerprints raises concerns that are insufficiently addressed in current policies. These concerns include infringing privacy, exposing participants to risks of legal action or violence, biasing surveillance results, and undermining trust in the health system. We set out key ethics and human rights considerations regarding the use of biometrics in HIV surveillance among these populations, and outline a typology of jurisdictions wherein such methods might be considered, based on data about legal, political, and social environments. In this Review, we suggest that the biometrics approach is not currently likely to be appropriate in many jurisdictions.

Sex Trade and Health Care Utilization Among People Living with HIV/AIDS

People living with HIV/AIDS (PLWH) are more likely to have a history of trading sex, but little research has examined whether trading sex is associated with lower health care utilization amongst PLWH. This study assesses this association with PLWH (N = 583) recruited and surveyed from seven community sites in six US cities participating in a multi-site community-based HIV test and treat initiative. Participants were 90.6% Black or Latino, 30.4% homeless, and 9.0% (1 in 11) sold sex (past 90 days). Most reported receiving HIV clinical care (63.9%, past 6 months) and HIV case management (68.9%, past year), but 35.7% reported a missed health care appointment (past 3 months). In adjusted regression models, trading sex was associated with a missed health care appointment (OR = 2.44) and receiving psychological assistance (OR = 2.31), past 90 days, but not receipt of HIV care or supportive HIV services. Trading sex may compromise consistent health care utilization among PLWH.

HIV Prevalence and Related Risk Factors in Men Who Have Sex with Men in Bamako, Mali: Findings from a Bio-behavioral Survey Using Respondent-Driven Sampling

Using respondent driven sampling, we conducted a cross-sectional bio-behavioral survey among men who have sex with men (MSM) in Bamako, Mali. Eligibility criteria included age ≥18 years and having had sex with another man in the last 6 months. We enrolled 552 MSM, 99.6% were tested for HIV. MSM in Bamako were young (69.6% ≤24 years) and educated (63.7% ≥secondary). HIV prevalence among MSM in Bamako was 13.7; 90.1% of HIV-infected men were unaware of their HIV status. Almost one-third had never been tested for HIV. Factors associated with higher odds of HIV included younger age, being receptive with last partner, condom breaking during anal sex in last 6 months, talking to peer educator about HIV, and having sexually transmitted infection symptoms in past year. The results suggest the need for enhanced HIV prevention and treatment services targeted at MSM in Bamako, with emphasis on repeated HIV testing.

"Booze is the main factor that got me where I am today": alcohol use and HIV risk for MSM in rural South Africa

Excessive alcohol consumption has been shown to increase HIV risk for men who have sex with men (MSM) and compromise HIV prevention behaviors. However, there is limited contextual understanding of alcohol use for MSM in rural sub-Saharan African settings, which can inform and direct HIV interventions. Applying an adaptation of PhotoVoice, we worked with 35 HIV-positive MSM who created photo-essays about alcohol and HIV in Mpumalanga. A semi-structured protocol was used in focus group discussions that were audio-recorded, translated and transcribed. Transcript data and visual data of 24 photo-essays were analyzed using a constant comparison approach. We found that participants used alcohol to build and sustain social networks, meet sexual partners, and enhance sexual experience. Excessive alcohol use was common, which was associated with increased HIV risk behaviors within a community of MSM who maintained multiple partnerships. Our study suggests that HIV interventions need to address excessive alcohol use to mitigate the associated HIV risk at both the individual and community levels.

Age bias in survey sampling and implications for estimating HIV prevalence in men who have sex with men: insights from mathematical modelling

Respondent-driven sampling (RDS) is widely used to estimate HIV prevalence in men who have sex with men (MSM). Mathematical models that are calibrated to these data may be compromised if they fail to account for selection biases in RDS surveys. To quantify the potential extent of this bias, an agent-based model of HIV in South Africa was calibrated to HIV prevalence and sexual behaviour data from South African studies of MSM, first reweighting the modelled MSM population to match the younger age profile of the RDS surveys (age-adjusted analysis) and then without reweighting (unadjusted analysis). The model estimated a median HIV prevalence in South African MSM in 2015 of 34.6% (inter-quartile range (IQR): 31.4-37.2%) in the age-adjusted analysis, compared with 26.1% (IQR: 24.1-28.4%) in the unadjusted analysis. The median lifetime risk of acquiring HIV in exclusively homosexual men was 88% (IQR: 82-92%) in the age-adjusted analysis, compared with 76% (IQR: 64-85%) in the unadjusted analysis. These results suggest that RDS studies may under-estimate the exceptionally high HIV prevalence rates in South African MSM because of over-sampling of younger MSM. Mathematical models that are calibrated to these data need to control for likely over-sampling of younger MSM.

Gender identity and HIV risk among men who have sex with men in Cape Town, South Africa

Gender identity plays a potentially important role contributing to HIV risk among MSM in South Africa. Where studies have included a focus on gender identity, MSM reporting gender non-conformity have been found to have a higher risk of being HIV positive than other MSM. This article examines HIV risk among gender non-conforming MSM in a sample of 316 MSM in Cape Town, South Africa. Reporting gender non-conformity was associated with higher HIV prevalence and increased HIV risk behaviour. Gender non-conformity was also associated with a higher likelihood of being unemployed and reporting low household incomes. These findings highlight the importance of gender-identity as a factor affecting access to HIV treatment, care, and prevention in South Africa and this is an issue that needs to be addressed in interventions targeting MSM populations.

Modelling the UNAIDS 90-90-90 treatment cascade for gay, bisexual and other men who have sex with men in South Africa: using the findings of a data triangulation process to map a way forward

A data triangulation exercise was carried out between 2013 and 2015 to assess the HIV epidemic and response among gay, bisexual and other men who have sex with men (GBMSM) in South Africa. We used the findings to assess progress in achieving the UNAIDS 90-90-90 goals for GBMSM in the country. Three scenarios were developed using different GBMSM population factors (2.0, 3.5 and 5.0% of males aged ≥15) to estimate the population size, HIV prevalence of 13.2-49.5%, and 68% of GBMSM knowing their status. Due to data gaps, general population data were used as estimates of GBMSM on antiretroviral therapy (ART) and virologically suppressed (25.7 and 84.0%, respectively). The biggest gap is access to ART. To address the data gap we recommend developing data collection tools, indicators, and further quantification of HIV cascades. Targeted testing, linkage to services and scaled-up prevention interventions (including pre-exposure prophylaxis) are also required.

High Acceptability and Increased HIV-Testing Frequency After Introduction of HIV Self-Testing and Network Distribution Among South African MSM

BACKGROUND

South African men who have sex with men (MSM) have a high burden of undiagnosed HIV infection and HIV-testing rates incommensurate with their risk. HIV self-testing (HIVST) may increase testing uptake, frequency, and earlier HIV detection and treatment.

SETTING

Gert Sibande and Ehlanzeni districts, Mpumalanga Province, South Africa.

METHODS

We conducted a longitudinal HIVST study among MSM between June 2015 and May 2017. Overall 127 HIV-negative MSM were provided with up to 9 test kits of their choice-oral fluid or blood fingerstick-to use themselves and distribute to their networks. Surveys conducted 3- and 6-month post-enrollment elicited information on HIVST experiences, preferences, acceptability, utilization, and distribution. We used generalized estimating equations to assess changes in testing frequency.

RESULTS

Ninety-one percent of participants self-tested. All participants who self-tested reported being likely to self-test again, with over 80% preferring HIVST to clinic-based testing. Fingerstick was preferred to oral fluid tests by approximately 2:1. Returning participants distributed 728 tests to sexual partners (18.5% of kits), friends (51.6%), and family (29.8%). Six participants seroconverted during the study, and 40 new diagnoses were reported among test recipients. Frequent (semi-annual) testing increased from 37.8% before the study to 84.5% at follow-up (P < 0.001), and participants reported anticipated frequent testing of 100% if HIVST were available compared with 84% if only clinic-testing were available in the coming year (P < 0.01).

CONCLUSIONS

HIVST use and network distribution is acceptable and feasible for MSM in South Africa and can increase testing uptake and frequency, potentially improving early detection among MSM and their networks.

"There is not a safe space where they can find themselves to be free": (Un)safe spaces and the promotion of queer visibilities among township males who have sex with males (MSM) in Cape Town, South Africa

Males who have sex with males (MSM) are prioritised in the global fight against HIV/AIDS, as a key affected population to receive HIV prevention, treatment, and HIV-related care and support (WHO, 2016). There is, however, limited empirical research conducted on how to engage communities of South African MSM in clinical HIV prevention research programs. The development of LGBTIQ safe spaces may potentially be a viable option to promote community-based engagement by bridging the divides between HIV-prevention researchers, marginalised queer populations, and other HIV-prevention stakeholders located in heteronormative spaces (Molyneux et al., 2016). We conducted ten in-depth, qualitative interviews with MSM safe space members who have been involved in HIV prevention research programs. Data were analysed using a thematic analytic strategy (Braun and Clarke, 2006). Our results indicate that the "safe spaces" currently operational in Cape Town are not stable spaces nor are they always safe, but they form part of a broader and much more long-term political and geographical strategy of inclusion and emancipation.

How social stigma sustains the HIV treatment gap for MSM in Mpumalanga, South Africa

There are gaps in HIV care for men who have sex with men (MSM) in African settings, and HIV social stigma plays a significant role in sustaining these gaps. We conducted a three-year research project with 49 HIV-positive MSM in two districts in Mpumalanga Province, South Africa, to understand the factors that inform HIV care seeking behaviors. Semi-structured focus group discussions and interviews were conducted in IsiZulu, SiSwati, and some code-switching into English, and these were audio-recorded, transcribed, and translated into English. We used a constant comparison approach to analyze these data. HIV social stigma centered around gossip that sustained self-diagnosis and delayed clinical care with decisions to use traditional healers to mitigate the impact of gossip on their lives. More collaboration models are needed between traditional healers and health professionals to support the global goals for HIV testing and treatment.

Comparing Provider and Client Preferences for HIV Prevention Services in South Africa among Men Who Have Sex with Men

Combination prevention efforts are now recommended toward reducing HIV incidence among men who have sex with men (MSM). Understanding the perceptions of both MSM and service providers is critical to informing the development of prevention packages and ultimately improving intervention effectiveness. This study assessed the preferences of MSM and health service providers in the administration of HIV-prevention efforts. Qualitative data were gathered from a series of separate MSM and health care provider focus groups in 2 South African cities. Participants discussed HIV-prevention services and MSM client experiences within South Africa and identified the 3 most important clinic characteristics and 3 most important HIV-prevention services for MSM clients. Priorities indicated by both MSM and health care providers were confidentiality of visit, friendly staff, and condoms, while discrepancies existed between MSM and providers regarding provider consistency and the provision of pre-exposure prophylaxis/post-exposure prophylaxis (PrEP/PEP) and lubricant as prevention methods. Effective interventions must address these discrepancies through the design of intervention and provider training to optimally accommodate MSM.

Substance Use and HIV Risk Among Men Who Have Sex With Men in Africa: A Systematic Review

BACKGROUND

Substance use and its relation to HIV risk among men who have sex in Africa, a population at high risk for HIV, has received little attention.

METHODS

This systematic review summarizes and discusses findings from 68 empirical studies, published between 1980 and 2016 that included data about substance use in men who have sex with men (MSM) in Africa.

RESULTS

Substance use has rarely been the primary focus of studies in African MSM. In general, measurement of substance use was suboptimal. Whereas prevalence of alcohol use varied across studies, partly resulting from variety in assessment strategies, it seemed higher than in the general male population across countries. Alcohol use was associated with sexual risk practices, but not with HIV infection. The most frequently reported drug used by African MSM was cannabis. The use of other drugs, such as cocaine and heroin seemed relatively rare, although injection drug use was exceptionally high in a few studies. As alcohol, drugs were regularly used in conjunction with sex. Both alcohol and drug use were often associated with other risk factors for HIV infection, including violence and transactional sex. No interventions were found addressing substance use among African MSM.

CONCLUSIONS

Given high HIV risk and prevalence in this population, substance use should be studied more in-depth, taking into account the specific social and cultural context. Assessment of substance use practices in this population has to be improved. The available information suggests, though, that there is an urgent need for interventions addressing substance use tailored to the needs of this critical population.

Assessing the Feasibility of Smartphone Apps for HIV-Care Research with MSM and Transgender Individuals in Mpumalanga, South Africa

There is an urgent need to develop the HIV treatment cascade for men who have sex with men (MSM) and transgender individuals in rural Mpumalanga, South Africa. Mhealth tools such as smartphone applications have the potential to support HIV self-care behaviors. We conducted an exploratory study with HIV-positive community leaders to understand their current uses of cell phones and smartphones and to assess their interest in an HIV research study that utilized a smartphone application for HIV care support. A total of 18 community leaders were recruited to complete a questionnaire and focus group. We found that a large proportion of participants had smartphone access and were interested in a research study that utilized a smartphone application with secure access measures. We conclude that smartphone applications for HIV care research are feasible based on access and interest by MSM and transgender individuals in this rural setting.

High acceptability of rapid HIV self-testing among a diverse sample of MSM from Buenos Aires, Argentina

INTRODUCTION

The objective of this study was to explore the acceptability of rapid HIV self-testing (RHST) among men who have sex with men (MSM).

METHODS

During 2006-2009, a sample of 500 MSM was recruited through Respondent Driven Sampling for an HIV prevalence/incidence study. Attitude toward RHST was explored among HIV negative MSM. Data were weighted prior to analyses.

RESULTS

Participants reported they were likely to buy RHST (74%), test themselves more frequently than they currently do (77%), and that the procedure would simplify testing (70%). Furthermore, 71% reported they would probably use it alone, 66% would use it with a steady partner, and 56% with a friend/partner. While a majority acknowledged that RHST use would deprive them of receiving counseling (61%), 74% declared they would go for help if they tested positive; 57% would use an RHST in order to avoid condoms. Probability of use surpassed 70% among gay and non-gay identified MSM as well as those with and without a previous HIV test. Those likely to buy RHST were older (p = 0.025) and more likely to identify as gay (p = 0.036). A total of 17% said they would think about killing themselves and 9% would attempt suicide if they tested positive. These MSM were more likely to be younger (p<0.001), with lower mood level (p<0.001) and greater feelings of loneliness (p = 0.026).

CONCLUSIONS

The high acceptability of RHST found among MSM should encourage the authorities to consider the possibility of offering it for self-testing, as it can improve early diagnosis and prevention of future transmissions. However, further research is needed to understand how to best disseminate RHST among MSM who wish to use it and to offer support and linkage to care for those who test HIV-positive.

The accuracy of HIV rapid testing in integrated bio-behavioral surveys of men who have sex with men across 5 Provinces in South Africa

We describe the accuracy of serial rapid HIV testing among men who have sex with men (MSM) in South Africa and discuss the implications for HIV testing and prevention.This was a cross-sectional survey conducted at five stand-alone facilities from five provinces.Demographic, behavioral, and clinical data were collected. Dried blood spots were obtained for HIV-related testing. Participants were offered rapid HIV testing using 2 rapid diagnostic tests (RDTs) in series. In the laboratory, reference HIV testing was conducted using a third-generation enzyme immunoassay (EIA) and a fourth-generation EIA as confirmatory. Accuracy, sensitivity, specificity, positive predictive value, negative predictive value, false-positive, and false-negative rates were determined.Between August 2015 and July 2016, 2503 participants were enrolled. Of these, 2343 were tested by RDT on site with a further 2137 (91.2%) having definitive results on both RDT and EIA. Sensitivity, specificity, positive predictive value, negative predictive value, false-positive rates, and false-negative rates were 92.6% [95% confidence interval (95% CI) 89.6-94.8], 99.4% (95% CI 98.9-99.7), 97.4% (95% CI 95.2-98.6), 98.3% (95% CI 97.6-98.8), 0.6% (95% CI 0.3-1.1), and 7.4% (95% CI 5.2-10.4), respectively. False negatives were similar to true positives with respect to virological profiles.Overall accuracy of the RDT algorithm was high, but sensitivity was lower than expected. Post-HIV test counseling should include discussions of possible false-negative results and the need for retesting among HIV negatives.

Brief Report: High HIV Incidence in a South African Community of Men Who Have Sex With Men: Results From the Mpumalanga Men's Study, 2012-2015

Cross-sectional studies among African men who have sex with men (MSM) populations demonstrate high HIV prevalence, but few incidence estimates exist. The Mpumalanga Men's Study in Gert Sibande, Mpumalanga province, South Africa, involved 3 serial cross-sectional surveys of MSM recruited through respondent-driven sampling between 2012 and 2015. Successive surveys recaptured a nested cohort of 179, contributing 144.3 person-years (PY) of observation. We observed 18 seroconversions, or incidence of 12.5/100 (PY) (95% confidence interval CI: 8.1 to 19.2/100 PY). Presumptions of high incidence among MSM were confirmed and demonstrate an urgent need for biomedical prevention and treatment programming for MSM in South Africa.

Community engagement in sexual health and uptake of HIV testing and syphilis testing among MSM in China: a cross-sectional online survey

INTRODUCTION

HIV and syphilis testing rates remain low among men who have sex with men (MSM) in low- and middle-income countries (LMICs). Community engagement has been increasingly used to promote HIV testing among key populations in high-income countries, often in settings with stronger civil society. This study aimed to assess socio-demographic, behavioural, and community engagement factors associated with HIV and syphilis testing among MSM in China.

METHODS

MSM ≥16 years old who had condomless sex in the past three months were recruited nationwide to complete a cross-sectional online survey in November 2015. Data were collected on socio-demographics, sexual behaviours, HIV testing, syphilis testing, and community engagement in sexual health. We defined community engagement in sexual health using six items assessing awareness and advocacy of sexual health programmes. The underlying factor structure of a 6-item community engagement scale was determined through exploratory factor analysis. Univariate and multivariable logistic regressions identified correlates of HIV and syphilis testing.

RESULTS

1189 MSM were recruited. 54% (647/1189) of men had ever tested for HIV and 30% (354/1189) had ever tested for syphilis. Factor analysis suggested three levels of community engagement (minimal, moderate, and substantial) and this model explained 79.5% of observed variance. A quarter (26%, 312/1189) reported none to minimal engagement, over one half (54%, 644/1189) reported moderate engagement, and a fifth (20%, 233/1189) reported substantial engagement. Multivariable logistic regression showed that MSM with greater community engagement in sexual health were more likely to have ever tested for HIV (substantial vs. no engagement: aOR 7.91, 95% CI 4.98-12.57) and for syphilis (substantial vs. no engagement: aOR 5.35, 95% CI 3.16-9.04).

CONCLUSION

HIV and syphilis testing are suboptimal among MSM in China. Community engagement may be useful for promoting testing in China and should be considered in intervention development and delivery. Further research is needed to better understand the role of LMIC community engagement in HIV interventions.

HIV risk and prevention among men who have sex with men in rural South Africa

Rural South African men who have sex with men (MSM) are likely to be underserved in terms of access to relevant healthcare and HIV prevention services. While research in urban and peri-urban MSM populations has identified a range of factors affecting HIV risk in South African MSM, very little research is available that examines HIV risk and prevention in rural MSM populations. This exploratory study begins to address this lack by assessing perceptions of HIV risk among MSM in rural Limpopo province. Using thematic analysis of interview and discussion data, two overarching global themes that encapsulated participants' understandings of HIV risk and the HIV risk environment in their communities were developed. In the first theme, "community experience and the rural social environment", factors affecting HIV risk within the broad risk environment were discussed. These included perceptions of traditional value systems and communities as homophobic; jealousy and competition between MSM; and the role of social media as a means of meeting other MSM. The second global theme, "HIV/AIDS knowledge, risk and experience", focused on factors more immediately affecting HIV transmission risk. These included: high levels of knowledge of heterosexual HIV risk, but limited knowledge of MSM-specific risk; inconsistent condom and lubricant use; difficulties in negotiating condom and lubricant use due to uneven power dynamics in relationships; competition for sexual partners; multiple concurrent sexual partnerships; and transactional sex. These exploratory results suggest that rural South African MSM, like their urban and peri-urban counterparts, are at high risk of contracting HIV, and that there is a need for more in-depth research into the interactions between the rural context and the specific HIV risk knowledge and behaviours that affect HIV risk in this population.

Learning to Live With HIV in the Rural Townships: A Photovoice Study of Men Who Have Sex With Men Living With HIV in Mpumalanga, South Africa

There is limited understanding about the health and well-being of men who have sex with men (MSM) with HIV infection living in rural African areas. We present the results of an adapted photovoice project with 35 MSM with HIV infection who live in townships in Mpumalanga, South Africa. The project was designed to explore the social factors that influenced HIV care. Twenty-four photo essays were developed by participants in focus group discussions that were audio-recorded and transcribed for analysis. Transcripts and photo essays were coded using a constant comparison approach combining researcher observation notes and reflection on participant-identified themes. Participants identified (a) a shared experience of illness and coming to terms with having HIV infection and (b) family and taverns as necessary support systems. The findings suggested that family- and tavern-based interventions might improve health outcomes for MSM newly diagnosed with HIV infection living in rural and semi-rural African communities.

Preventing HIV among adolescents with oral PrEP: observations and challenges in the United States and South Africa

INTRODUCTION

Adolescents and young adults aged <25 are a key population in the HIV epidemic, with very high HIV incidence rates in many geographic settings and a large number who have limited access to prevention services. Thus, any biomedical HIV prevention approach should prepare licensure and implementation strategies for young populations. Oral pre-exposure prophylaxis (PrEP) is the first antiretroviral-based prevention intervention with proven efficacy across many settings and populations, and regulatory and policy approvals at global and national levels are occurring rapidly. We discuss available data from studies in the United States and South Africa on the use of oral PrEP for HIV prevention in adolescent minors, along with some of the implementation challenges.

DISCUSSION

Ongoing studies in the United States and South Africa among youth under the age of 18 should provide the safety data needed by the end of 2016 to contribute to licensure of Truvada as daily PrEP in adolescents. The challenges of completing these studies as well as foreseeable broader challenges highlighted by this work are presented. Adherence to daily PrEP is a greater challenge for younger populations, and poor adherence was associated with decreased efficacy in all PrEP trials. Individual-level barriers include limited familiarity with antiretroviral-based prevention, stigma, product storage, and social support. Structural challenges include healthcare financing for PrEP, clinician acceptability and comfort with PrEP delivery, and the limited youth-friendly health services available. These challenges are discussed in the context of the work done to date in the United States and South Africa, but will likely be magnified in the setting of limited resources in many other countries that are heavily impacted by HIV.

CONCLUSIONS

Adolescent populations are particularly vulnerable to HIV, and oral PrEP in these populations is likely to have an impact on population-level HIV incidence. The challenges of disseminating an HIV biomedical prevention tool requiring daily usage in adolescents are formidable, but addressing these issues and starting dialogues will lay the groundwork for the many other HIV prevention tools now being developed and tested.
