HIV incidence among gay men and other men who have sex with men in 2020: where is the epidemic heading?

Disease burden of AIDS in last 30-year period and its predicted level in next 25-years based on the global burden disease 2019

BACKGROUND

This study examines global trends in acquired immune deficiency syndrome (AIDS) incidence, mortality, and disability-adjusted life years (DALYs) from 1990 to 2019, focusing on regional disparities in AIDS incidence, mortality, and DALYs across various levels of socio-demographic index (SDI). It also investigates variations in AIDS incidence, mortality, and DALYs across different age groups, and projects specific trends for the next 25 years.

METHODS

Comprehensive data on AIDS from 1990 to 2019 in 204 countries and territories was obtained from a GBD study. This included information on AIDS incidence, mortality, DALYs, and age-standardized rates (ASRs). Projections for AIDS incidence and mortality over the next 25 years were generated using the Bayesian age-period-cohort model.

RESULTS

From 1990 to 2019, the global incidence of HIV cases increased from 1,989,282 to 2,057,710, while the age-standardized incidence rate (ASIR) decreased from 37.59 to 25.24 with an estimated annual percentage change (EAPC) of -2.38. The ASIR exhibited an upward trend in high SDI and high-middle SDI regions, a stable trend in middle SDI regions, and a downward trend in low-middle SDI and low SDI regions. In regions with higher SDI, the ASIR was higher in males than in females, while the opposite was observed in lower SDI regions. Throughout 1990 to 2019, the age-standardized death rate (ASDR) and age-standardized DALY rate remained stable, with EAPCs of 0.24 and 0.08 respectively. Countries with the highest HIV burden affecting women and children under five years of age are primarily situated in lower SDI regions, particularly in sub-Saharan Africa. Projections indicate a significant continued decline in the age-standardized incidence and mortality rates of AIDS over the next 25 years, for both overall and by gender.

CONCLUSIONS

The global ASIR decreased from 1990 to 2019. Higher incidence and death rates were observed in the lower SDI region, indicating a greater susceptibility to AIDS among women and < 15 years old. This underscores the urgent need for increased resources to combat AIDS in this region, with focused attention on protecting women and < 15 years old as priority groups. The AIDS epidemic remained severe in sub-Saharan Africa. Projections for the next 25 years indicate a substantial and ongoing decline in both age-standardized incidence and mortality rates.

Characterizing Socioecological Markers of Differentiated HIV Risk Among Men Who Have Sex with Men in Indonesia

HIV prevention programs typically focus on changing individuals' risk behaviors, often without considering the socioecological factors that can moderate this risk. We characterized HIV risk among men who have sex with men (MSM) in Indonesia (n = 1314) using latent class analysis and used multinomial logistic regression to identify latent class relationships with demographics, social/sexual networks, and community-level socioecological indicators of HIV risk. Three HIV risk latent classes were identified-"Sexually Moderate" (n = 333), "Sexual Explorative" (n = 575), and "Navigating Complexities" (n = 406). Using "Sexually Moderate" (lowest risk) as the reference group, MSM in the "Sexual Explorative" class had additional social/sexual network-level risks (meeting partner(s) using both online and offline methods [RR = 3.8; 95%CI 1.7-8.6] or general social media and gay-specific online platforms [RR = 2.6; 95%CI 1.9-3.6] to meet partners, group sex [RR = 10.9; 95%CI 4.5-25.4], transactional sex [RR = 1.6; 95%CI 1.2-2.2]), and community-level risks (experiencing homosexual-related assaults [RR = 1.4; 95%CI 1.1-1.9]). MSM in the "Navigating Complexities" class had additional social/sexual network-level risks (low social support [RR = 1.6; 95%CI 1.1-2.5], less disclosure of their sexuality [RR = 1.4; 95%CI 1.0-1.9]) and community-level risks (higher internalized homonegativity scores [RR = 1.2; 95%CI 1.1-1.4], ever experiencing homosexual-related assaults [RR = 1.4:95%CI 1.1-1.9], less exposure to HIV/STI health promotion [RR = 0.7; 95%CI 0.5-0.9], attending STI-related services in the past 6 months [RR = 0.6; 95%CI 0.4-0.8]). Co-occurring individual and socioecological risk recommend holistic HIV prevention strategies tailored to consider the social and structural conditions of MSM in Indonesia are needed.

Perspectives on unhealthy alcohol use among men who have sex with men prescribed HIV pre-exposure prophylaxis: A qualitative study

Unhealthy alcohol use is a common, often unaddressed behavior associated with increased risk for acquisition of HIV and may also be associated with decreased adherence to oral pre-exposure prophylaxis (PrEP) among gay, bisexual, and other men who have sex with men (MSM) living in the United States. To inform future alcohol-reduction interventions among individuals engaging in PrEP care, we sought to explore perspectives on alcohol use, PrEP adherence, and the acceptability of alcohol use treatment options for MSM prescribed oral formulations of PrEP in the Northeastern United States. Between February 2019 and July 2020, we conducted semi-structured interviews with 15 MSM without HIV who were prescribed PrEP and screened positive for unhealthy alcohol use with AUDIT-C ≥ 4 and were receiving care in Providence, Rhode Island or New Haven, Connecticut. Interviews were coded and analyzed using thematic analysis. Three themes emerged: 1) Consequences of fluctuations in drinking 2) Alcohol use negatively impacts health and relationships; and 3) Desire for a multimodal approach to treatment of unhealthy alcohol use. Our findings support the need to raise awareness of potential alcohol-related harms, address the spectrum of unhealthy alcohol use among MSM prescribed PrEP, and the acceptability and preferences for alcohol reduction interventions within PrEP programs.

HIV-1 protective epitope-specific CD8+ T cells in HIV-1-exposed seronegative individuals

Although previous studies have reported HIV-1-specific T cell responses in HIV-1-exposed seronegative (HESN) individuals, there has been no detailed analysis of these T cells against HIV-1 infection. We investigated HIV-1-specific CD8+ T cell responses in 200 Japanese HESN men who have sex with men (MSM). T cell responses to 143 well-characterized HIV-1 epitope peptides were analyzed by intracellular cytokine staining assay consisting of 3-week cultures of PBMCs stimulated with peptides. HLA-B∗51:01-restricted Pol TI8-specific and HLA-A∗02:06-restricted Pol SV9-specific CD8+ T cells were identified in two and one individuals, respectively, whereas CD8+ T cells specific for other HLA-A∗02:06-restricted or HLA-B∗51:01 epitopes were not present in these individuals. These epitope-specific T cells recognized HIV-1-infected cells. Because these two epitopes were previously reported to be protective in HIV-1-infected individuals, these protective epitope-specific T cells might suppress HIV-1 replication in HESN-MSM individuals. The present study suggests the contribution of protective epitope-specific T cells to protection against HIV-1 infection.

Barriers to and enablers of the HIV services continuum among gay and bisexual men worldwide: Findings from the Global Men's Health and Rights Study

OBJECTIVES

To assess ecological, structural, community and individual level correlates of health services utilization along a continuum of HIV care, and sexual health and support services among gay and bisexual men worldwide.

METHODS

Using a nonprobability internet sample of 6,135 gay and bisexual men, we assessed correlates of utilization of health services. Chi-Square Tests of Independence were performed to assess drop off along a continuum of HIV care. Multivariable logistic regression analyses using generalized estimating equation models were conducted adjusting for geographic region and clustering by country. In multivariable analyses, we determined the association between utilization outcomes, and ecologic, structural, community and individual correlates by fitting separate generalized estimating equation (GEE) logistic regression models for each of the outcomes, fitted with robust SEs, and accounting for clustering by country. Stratified by sexual identity, analyses adjusted for variables that could influence HIV-related health outcomes including racial/ethnic minority status, participant age, insurance, ability to make ends meet, as well as country-level income (income of country of residence defined by the World Bank).

RESULTS

Among men living with HIV (n = 1001), being in HIV care (n = 867) was associated with being on ART (X2 = 191.17, p < .001), and viral load suppression (X2 = 14.03, p < .001); and using ART (n = 840) was associated viral load suppression (X2 = 21.66, p < .001). Overall, the pattern of utilization outcomes were similar for both gay and bisexual men. For example, utilization of PrEP, being in HIV care and utilization of most of the sexual health and support services were negatively associated with sexual stigma. Whereas, utilization of most HIV prevention, and sexual health and support services were positively associated with provider discrimination. Utilization of all HIV prevention and all sexual health services were positively associated with greater community engagement, and receiving services from LGBT-led organizations. Bisexual men had higher odds of reporting provider discrimination when utilizing condom services (gay: AOR = 1.14, [0.95-1.36]; bisexual: 1.58, [1.10-2.28]), PrEP (gay: AOR = 1.06, [0.77-1.45]; bisexual: AOR = 2.14, [1.18-3.89], mental health services (gay: AOR = 1.03, [0.86-1.23]; bisexual: AOR = 1.32, [1.07-1.64]), and community-based support (gay: AOR = 1.23, [1.05-1.45]; bisexual: AOR = 1.49, [1.14-1.93]) than gay men. Bisexual men also reported higher odds of accessing services from LGBT-led organizations when utilizing PrEP (gay: AOR = 5.26, [2.50-11.05]; bisexual: AOR = 7.12, [3.16-16.04]), and community-based support/self-help groups/individual counseling (gay: AOR = 2.63, [1.72-4.01]; bisexual: AOR = 3.35, [2.30-4.88].

CONCLUSIONS

It is essential that barriers to health services utilization be addressed at structural and community levels. Structural interventions should be designed to reduce sexual stigma, as well as train and sensitize healthcare providers; and strengthen community level interventions that bring gay and bisexual men together to lead comprehensive health services.

Creating an Inclusive Urology Practice

Purpose of Review

Patients seeking urologic care come from diverse backgrounds. Therefore, clinics should strive for inclusivity to make all patients feel comfortable seeing a urologist. This review aims to outline and analyze literature relevant to the care of LGTBQIA+ (lesbian, gay, transgender/transexual, queer/questioning, intersex, asexual/allies, nonbinary/genderqueer +), racial and ethnic minorities, those who have disabilities, and those with a high body mass index (BMI). Although this review article presents the care of diverse communities separately, there is an overlap of the various social axes influencing healthcare outcomes. Healthcare workers should be open-minded to learning about evolving community needs.

Recent Findings

Creating a safe space for LGTBQIA+ requires understanding terminology, awareness of community-specific challenges and health risks, and changing heteronormative behaviors built into medicine. Specific clinical care delivery structural processes and patient-physician-centered practices can make a clinic welcoming for patients from underrepresented backgrounds and with disabilities. BMI surgical requirements may pose barriers to care, and if implemented, there should be assistance to reach specified weight goals.

Summary

Creating an inclusive urology clinical practice takes time, but it can be achieved by building a collaborative team. Treating patients with consideration of their personal identities and social determinants of health will lead to better patient-center care and health outcomes.

Deep learning and social network analysis elucidate drivers of HIV transmission in a high-incidence cohort of people who inject drugs

Globally, people who inject drugs (PWID) experience some of the fastest-growing HIV epidemics. Network-based approaches represent a powerful tool for understanding and combating these epidemics; however, detailed social network studies are limited and pose analytical challenges. We collected longitudinal social (injection partners) and spatial (injection venues) network information from 2512 PWID in New Delhi, India. We leveraged network analysis and graph neural networks (GNNs) to uncover factors associated with HIV transmission and identify optimal intervention delivery points. Longitudinal HIV incidence was 21.3 per 100 person-years. Overlapping community detection using GNNs revealed seven communities, with HIV incidence concentrated within one community. The injection venue most strongly associated with incidence was found to overlap six of the seven communities, suggesting that an intervention deployed at this one location could reach the majority of the sample. These findings highlight the utility of network analysis and deep learning in HIV program design.

Modeling the potential impact of pre-exposure prophylaxis for HIV among men who have sex with men in Cameroon

Background

Men who have sex with men (MSM) are consistently burdened by HIV at higher levels than other adults. While HIV prevention programs for MSM are growing in coverage and quality, HIV incidence remains high. In response, pre-exposure prophylaxis (PrEP) was introduced in 2019 to support HIV risk reduction among MSM in Cameroon. Understanding how PrEP initiation programs will change the HIV prevalence among MSM in Cameroon is important to developing effective programs.

Methods

This study uses a mathematical model to simulate population-level HIV transmission among MSM in the cities of Yaoundé and Douala, Cameroon. PrEP is incorporated into the model at rates that equal 25%, 50%, or 75% coverage after twenty years to assess the potential effects on HIV prevalence among MSM, requiring annual initiation rates of 2.5%, 6.8%, and 17.2% for Yaoundé and 2.2%, 5.6%, and 13.4% for Douala, respectively. The data utilized for this model are from a cross sectional study which recruited MSM through respondent-driven sampling of MSM in two major cities in Cameroon: Yaoundé and Douala.

Results

The model estimated an HIV prevalence of 43.2% among MSM, annual HIV diagnoses of 300 per 10,000 MSM and antiretroviral therapy (ART) coverage of 53.9% in Yaoundé. In Douala, estimated prevalence is 26.5% among MSM, 167 per 10,000 MSM annual diagnoses and ART coverage of 72.0%. Standalone PrEP interventions aimed at 50% coverage at the end of a 20-year program would reduce the prevalence from 43.2% to 35.4% in Yaoundé and from 26.5 to 20.1% in Douala. Combining PrEP with a 10% increase in HIV testing would decrease the number of MSM living with HIV and unaware of their status from 9.8 to 6.0% in Yaoundé and from 8.7 to 4.6% in Douala.

Conclusions

PrEP would be beneficial in reducing prevalence even at varying initiation and coverage levels. Combination of PrEP and increased HIV testing further decreased the number of undiagnosed MSM. This study supports the utility of implementing PrEP as part of comprehensive HIV prevention programming among MSM in Cameroon.

HIV incidence among men who have sex with men (MSM) in Metro Manila, the Philippines: A prospective cohort study 2014-2018

The human immunodeficiency virus (HIV) epidemic in the Philippines has been driven by sexual transmission among men who have sex with men (MSM) over the past 2 decades. As the incidence of HIV infection among MSM has not been extensively evaluated, this study aimed to determine the incidence of HIV infections and the associated risk factors among MSM in Metro Manila, Philippines. This prospective cohort study was conducted in 2 community centers in Metro Manila, the Philippines, between March 2014 and December 2018. MSM who had anal or oral sex in the past 12 months, aged ≥18 years, and confirmed HIV-negative status were enrolled. Participants were followed up every 3 months with repeat HIV testing and assessment of HIV-related practices. Of the 708 MSM included in this study, a total of 59 HIV seroconversions occurred during the follow-up, resulting in an incidence of 2.7 (95% confidence interval: 2.1-3.5) per 100 patient-years. Multivariate risk regression analysis indicated that age (P = .002) and anal sex with a consensual male partner in the past 3 months (P = .039) were significantly associated with HIV infection. Our study has shown high rates of incident HIV infection among Filipino MSM. This demonstrates the need for effective HIV prevention, surveillance, treatment, and intervention strategies targeting this population.

The associations of incarceration and depression with healthcare experiences and utilization among Black men who have sex with men in HPTN 061

Associations of incarceration with healthcare access and utilization among Black sexual minority men (BSMM) and differences in association among those with and without pre-incarceration symptoms of depression were measured. Secondary analysis using survey data from the longitudinal cohort HIV Prevention Trials Network 061 study was conducted among 1553 BSMM from six major U.S. cities from 2009 to 2011. We used modified log-binomial regression with robust standard errors to estimate associations of incarceration (reported at 6 month follow-up) on next six-month healthcare utilization and access (reported at the 12 month follow-up). We tested the significance of baseline depressive symptoms by incarceration interaction and reported differences in associations when observed. Participants with a history of incarceration were more likely to have depressive symptoms at baseline compared to those without. Recent incarceration was associated with almost twice the risk of mistrust in healthcare providers and emergency room utilization. Among men reporting depressive symptoms, a history of incarceration was associated with almost tripled risk of reporting providers do not communicate understandably. Among those with depression, one in five reported a missed visit regardless of incarceration status.

Interest In and Uptake of HIV Pre-Exposure Prophylaxis (PrEP): A Cross-Sectional Study of High-Risk Patients in Western Canada

Rationale

Pre-exposure prophylaxis (PrEP) is a highly effective, evidence-based HIV prevention strategy. However, its use in the city of Saskatoon, Saskatchewan province of western Canada, is relatively new. Therefore, this study aimed to examine the interest and uptake of PrEP and investigate factors associated with HIV PrEP by high-risk patients.

Methods 

A cross-sectional, self-administered survey of patients attending Saskatoon’s Public Health Services Sexual Health Clinic was conducted from October until December 2018. The primary outcome was the interest in taking PrEP to reduce the risk of HIV infection. This outcome was evaluated for its association with potential correlates, which included: sociodemographic characteristics, HIV risk perception, prior PrEP awareness, and sexual behaviors/lifestyles. Descriptive, univariate, and multivariate analyses were used to pursue our research objectives.

Results

One hundred forty-one participants were recruited from a sexual health clinic in Saskatoon. The median age (interquartile range) was 26 (22-31) years. The median number of partners (interquartile range) was 3 (2-4) partners. A total of 66.0% of participants were unaware of PrEP, and almost half ( 49.6%) indicated an interest in taking PrEP. Among those disinterested in PrEP, 49.3% perceived minimal HIV risk, 35.2% expressed concern regarding side effects, 28.1% cited the added need for condom use, 23.9% indicated incomplete effectiveness, and 22.5% did not wish to undergo regular bloodwork. Multivariate analysis showed that interested patients were more likely to have been previously aware of PrEP (OR: 2.6, p-value = 0.03), perceived themselves to be vulnerable to HIV (OR: 15.7, p = <0.0001), or were unsure about their risk (OR: 3.9, p = 0.001).

Conclusion

This study suggests that a lack of knowledge regarding personal HIV risk and PrEP as a preventive option may influence PrEP interest. There lies a need for more health promotion campaigns around the health benefits of PrEP, including literacy efforts on HIV risk, concerns around side effects, and associated blood work with PrEP use.

Social Media-Based Secondary Distribution of Human Immunodeficiency Virus/Syphilis Self-testing Among Chinese Men Who Have Sex with Men

BACKGROUND

Social media and secondary distribution (distributing self-testing kits by indexes through their networks) both show strong promise to improve human immunodeficiency virus (HIV) self-testing uptake. We assessed an implementation program in Zhuhai, China, which focused on the secondary distribution of HIV/syphilis self-test kits among men who have sex with men (MSM) via social media.

METHODS

Men aged ≥16 years, born biologically male, and ever had sex with another man were recruited as indexes. Banner ads on a social media platform invited the participants to apply for up to 5 self-test kits every 3 months. Index men paid a deposit of US$15/kit refundable upon submitting a photograph of a completed test result via an online submission system. They were informed that they could distribute the kits to others (referred to as "alters").

RESULTS

A total of 371 unique index men applied for 1150 kits (mean age, 28.7 [standard deviation, 6.9] years), of which 1141 test results were returned (99%). Among them, 1099 were valid test results; 810 (74%) were from 331 unique index men, and 289 tests (26%) were from 281 unique alters. Compared to index men, a higher proportion of alters were naive HIV testers (40% vs 21%; P < .001). The total HIV self-test reactivity rate was 3%, with alters having a significantly higher rate than indexes (5% vs 2%; P = .008). A total of 21 people (3%) had a reactive syphilis test result.

CONCLUSIONS

Integrating social media with the secondary distribution of self-test kits may hold promise to increase HIV/syphilis testing coverage and case identification among MSM.

Perceived Interruptions to HIV Prevention and Treatment Services Associated With COVID-19 for Gay, Bisexual, and Other Men Who Have Sex With Men in 20 Countries

BACKGROUND

The coronavirus pandemic has necessitated a range of population-based measures to stem the spread of infection. These measures may be associated with disruptions to other health services including for gay, bisexual, and other men who have sex with men (MSM) at risk for or living with HIV. Here, we assess the relationship between stringency of COVID-19 control measures and interruptions to HIV prevention and treatment services for MSM.

SETTING

Data for this study were collected between April 16, 2020, and May 24, 2020, as part of a COVID-19 Disparities Survey implemented by the gay social networking app, Hornet. Pandemic control measures were quantified using the Oxford Government Response Tracker Stringency Index: each country received a score (0-100) based on the number and strictness of 9 indicators related to restrictions, closures, and travel bans.

METHODS

We used a multilevel mixed-effects generalized linear model with Poisson distribution to assess the association between stringency of pandemic control measures and access to HIV services.

RESULTS

A total of 10,654 MSM across 20 countries were included. Thirty-eight percent (3992/10,396) reported perceived interruptions to in-person testing, 55% (5178/9335) interruptions to HIV self-testing, 56% (5171/9173) interruptions to pre-exposure prophylaxis, and 10% (990/9542) interruptions to condom access. For every 10-point increase in stringency, there was a 3% reduction in the prevalence of perceived access to in-person testing (aPR: 0·97, 95% CI: [0·96 to 0·98]), a 6% reduction in access to self-testing (aPR: 0·94, 95% CI: [0·93 to 0·95]), and a 5% reduction in access to pre-exposure prophylaxis (aPR: 0·95, 95% CI: [0·95 to 0·97]). Among those living with HIV, 20% (218/1105) were unable to access their provider; 65% (820/1254) reported being unable to refill their treatment prescription remotely.

CONCLUSIONS

More stringent responses were associated with decreased perceived access to services. These results support the need for increasing emphasis on innovative strategies in HIV-related diagnostic, prevention, and treatment services to minimize service interruptions during this and potential future waves of COVID-19 for gay men and other MSM at risk for HIV acquisition and transmission.

Prevalence of condomless anal intercourse and associated risk factors among men who have sex with men in Bamako, Mali

BACKGROUND

Men who have sex with men (MSM) are disparately impacted by HIV in sub-Saharan Africa and condomless anal intercourse (CAI) is a major driver of HIV transmission. The objective of the current study was to identify factors associated with CAI among MSM in Bamako, Mali, among whom HIV prevalence was 13.7%.

METHODS

A bio-behavioral survey was conducted between October 2014 and February 2015 using respondent-driven sampling to recruit 552 adult MSM. Weighted statistical analyses were conducted to determine the prevalence of CAI with one's most recent male partner and survey logistic procedures were used to identify associated factors.

RESULTS

The prevalence of CAI with one's most recent male partner was 40.7%. Associated factors included: inability to get a condom when needed (aOR = 5.8, 95%CI: 2.7-12.3) and believing CAI is acceptable under some circumstances (aOR = 8.4, 95%CI: 4.4-16.2).

CONCLUSIONS

Programs addressing HIV among MSM in Mali should aim to increase access to condoms and education about HIV prevention through consistent condom use during anal intercourse.

HIV incidence and factors associated with testing positive for HIV among men who have sex with men and transgender women in Myanmar: data from community-based HIV testing services

Introduction

In Myanmar, men who have sex with men (MSM) and transgender women (TW) are disproportionately affected by HIV, despite national HIV program scale‐up. However, limited HIV surveillance capacity prevents monitoring of epidemic trends and program impact. This study aimed to estimate HIV prevalence and incidence and explore associated sexual risk behaviours among MSM and TW clients attending HIV testing clinics in Myanmar.

Methods

An electronic data management system was implemented in two community‐based, MSM and TW ‐tailored HIV testing clinics in Myanmar in August 2016. Unique client identifiers enabled prospective monitoring of service engagement, testing frequency and outcomes. We estimated HIV incidence and rate of HIV diagnosis at baseline testing visit among clients over a 15 month period. Correlates of HIV diagnoses were identified using multivariable logistic regression.

Results

2794 MSM and TW were tested for HIV. At their baseline test, 38% of clients reported any previous testing and 93% reported being sexually active over the previous three months, with 74% reporting sex with casual male partners and 28% reporting consistent condom use with casual partners. 291 clients tested positive for HIV for the first time at baseline (10.4%; 95% CI: 9.3 to 11.6). Twelve incident cases were detected among 279 clients receiving ≥2 tests (incidence = 10.1 per 100 person‐years; 95% CI: 5.73 to 17.8). HIV diagnosis at baseline was significantly associated with being a transgender woman or a non‐openly disclosing man who has sex with men, age 26 to 39 years, and reporting no testing history.

Conclusions

High HIV incidence and new diagnoses being associated with reporting no testing history points to undiagnosed HIV driving transmissions in Myanmar. Repeat testing was uncommon. HIV programs in Myanmar must focus on promoting frequent HIV testing alongside adequate coverage of education and primary prevention interventions among MSM and TW.

The feasibility of recruiting and retaining men who have sex with men and transgender women in a multinational prospective HIV prevention research cohort study in sub-Saharan Africa (HPTN 075)

INTRODUCTION

Men who have sex with men (MSM) and transgender women (TGW) in sub-Saharan Africa (SSA) are profoundly affected by HIV with high HIV prevalence and incidence. This population also faces strong social stigma and legal barriers, potentially impeding participation in research. To date, few multi-country longitudinal HIV research studies with MSM/TGW have been conducted in SSA. Primary objective of the HIV Prevention Trials Network (HPTN) 075 study was to assess feasibility of recruiting and retaining a multinational prospective cohort of MSM/TGW in SSA for HIV prevention research.

METHODS

HPTN 075, conducted from 2015 to 2017, was designed to enroll 400 MSM/TGW at four sites in SSA (100 per site: Kisumu, Kenya; Blantyre, Malawi; Cape Town, South Africa; and Soweto, South Africa). The number of HIV-positive persons was capped at 20 per site; HIV-positive persons already in care were excluded from participation. The one-year study included five biobehavioural assessments. Community-based input and risk mitigation protocols were included in study design and conduct.

RESULTS

Of 624 persons screened, 401 were enrolled. One in five participants was classified as transgender. Main reasons for ineligibility included: (a) being HIV positive after the cap was reached (29.6%); (b) not reporting anal intercourse with a man in the preceding three months (20.6%); and (c) being HIV positive and already in care (17.5%). Five (1.2%) participants died during the study (unrelated to study participation). 92.9% of the eligible participants (368/396) completed the final study visit and 86.1% participated in all visits. The main, overlapping reasons for early termination included being (a) unable to adhere to the visit schedule, predominantly because of relocation (46.4%), and (b) unable to contact the participant (32.1%). Participants reported strong motivation to participate and few participation barriers. Four participants reported social harms (loss of confidentiality and sexual harassment by study staff) that were successfully addressed.

CONCLUSIONS

HPTN 075 successfully enrolled a multinational sample of MSM/TGW in SSA in a prospective HIV prevention research study with a high retention rate and few documented social harms. This supports the feasibility of conducting large-scale research trials in this population to address its urgent, unmet HIV prevention needs.

Early Anal Sex Experience Among Men Who Have Sex with Men in Dar Es Salaam Tanzania: Implications for HIV Prevention and Care

Early age at first sex experience has been attributed to medical and psychological consequences, including practice of risk behaviors and HIV infection later in life. Studies have examined early heterosexual experience, but little is known about early anal sexual experience among men who have sex with men (MSM) in Africa. We conducted a time to event analysis to examine the extent and role of early anal sexual experience and HIV risk and infection in the largest MSM survey in Africa. A total of 753 MSM with a mean age of 26.5 years and that at first anal sexual experience of 18.3 years participated. Of those who participated, 29.0% (219/753) had their first anal sexual experience at age below 15. MSM reporting early anal sexual experience were young, had men as first sexual partner (adjusted hazard ratio-AHR, 4.75; 95%CI: 3.51-6.43), assumed receptive position during last anal sex (AHR, 3.25; 95%CI: 2.42-4.35), had anal sex as first penetrative sexual experience (AHR, 5.05, 95%CI; 3.68-6.97), had unprotected first anal sex (AHR, 1.55, 95%CI: 1.03-2.33), not preferring women for sex (AHR, 2.78; 95%CI: 2.11-3.67), had non-consensual first sex (AHR, 1.53, 95%CI: 1.10-9.41), and HIV positive (AHR, 1.75; 95%CI: 1.21-2.50). A third of MSM engaged in anal sex at an early age and were more likely to report sexual abuse, practice HIV risk behaviors, and been HIV seropositive. Roll-out of the existing Comprehensive Guideline for HIV Treatment and Care for key population in Tanzania should be implemented alongside measures addressing sexual abuse among young people.

Using Digital Communication Technology to Increase HIV Testing Among Men Who Have Sex With Men and Transgender Women: Systematic Review and Meta-Analysis

BACKGROUND

HIV continues to disproportionately affect men who have sex with men (MSM) and transgender women (TW). Undiagnosed HIV is a major driver of HIV transmission rates, and increasing the uptake of regular HIV testing and facilitating timely initiation of HIV treatment is a global HIV prevention priority. However, MSM and TW experience a range of barriers that limit their access to testing and other prevention services. Given their growing ubiquity, digital communication technologies are increasingly being used to support HIV prevention efforts, and a growing number of studies have trialed the use of digital technology to promote HIV testing among MSM and TW.

OBJECTIVE

We undertook a systematic review and meta-analysis to assess the impact of digital communication technology on HIV testing uptake among MSM and TW. Subanalyses aimed to identify the features and characteristics of digital interventions associated with greater impact.

METHODS

A systematic literature review was undertaken using select databases and conference repositories. Studies describing the use of a digital technology-internet-enabled devices, including phones, tablets, and computers-to increase HIV testing uptake among MSM or TW using either randomized or observational cohort design with measurement of HIV testing rates measured pre- and postintervention, and published in English between 2010 and 2018 were included. Pooled effect estimates were calculated using a random effects meta-analysis. Subanalyses calculated effect estimates grouped by selected features of digital interventions.

RESULTS

A total of 13 randomized or observational studies were included in the final review. Digital interventions most commonly used mainstream, existing social media platforms (n=7) or promotion through online peer educators (n=5). Most interventions (n=8) were categorized as interactive and allowed user engagement and most directly facilitated testing (n=7) either by providing self-testing kits or referral to testing services. A total of 1930 participants were included across the 13 studies. HIV testing uptake among MSM and TW exposed to digital interventions was 1.5 times higher than that of unexposed MSM and TW (risk ratio [RR] 1.5; 95% CI 1.3-1.7). Subanalyses suggested an increased impact on HIV testing uptake among interventions that were delivered through mainstream social media-based platforms (RR 1.7; 95% CI 1.3-2.1), included direct facilitation of HIV testing (RR 1.6; 95% CI 1.4-1.9), were interactive (RR 1.6; 95% CI 1.4-1.8), and involved end users in the design process (RR 1.6; 95% CI 1.3-2.0).

CONCLUSIONS

These findings provide broad support for the integration of technology with existing approaches to promote and facilitate HIV testing among MSM and TW. Our findings identified key features that may be associated with greater impact on HIV testing uptake and can be used to inform future development efforts given the growing interest and application of digital technologies in HIV prevention.

A Mobile Sexual Health App on Empowerment, Education, and Prevention for Young Adult Men (MyPEEPS Mobile): Acceptability and Usability Evaluation

BACKGROUND

HIV incidence among young adult men who have sex with men (MSM), particularly among black and Latino men, continues to rise. As such, continued HIV prevention interventions for young MSM of color are of utmost importance. Male Youth Pursuing Empowerment, Education and Prevention around Sexuality (MyPEEPS) Mobile is a comprehensive HIV prevention and sexual health education smartphone app initially created to promote sexual health and HIV prevention among adolescent sexual minority young men aged 13 to 18 years.

OBJECTIVE

The objective of this study was to critically appraise the acceptability and usability of MyPEEPS Mobile for young adult MSM aged 19 to 25 years.

METHODS

Study participants used the mobile app, completed usability questionnaires and in-depth interviews, and reported their experience using the app. Analysis of interview data was guided by the Unified Theory of Acceptance and Use of Technology (UTAUT) to better understand the usability and acceptability of this intervention for young adults. Interview data were coded using the following constructs from the UTAUT model: performance expectancy, effort expectancy, and social influence.

RESULTS

A total of 20 young adult MSM (n=10 in Chicago, Illinois, and n=10 in New York, New York) were enrolled in the study. Participants reported that MyPEEPS Mobile was free of functional problems (Health Information Technology Usability Evaluation Scale scores and Post-Study System Usability Questionnaire scores consistent with high usability), easy to use, and useful, with an engaging approach that increased acceptability, including the use of avatars and animation, and inclusive representation of the diverse identities by race and ethnicity, gender identity, and sexual orientation. Recommended areas for improving MyPEEPS Mobile for the target demographic included more adult-oriented graphics, advanced educational content, scenarios for youth with more sexual experience, and search function to increase accessibility of key content.

CONCLUSIONS

Overall, young adult MSM aged 19 to 25 years described the MyPEEPS Mobile as educational, informative, and usable for their sexual health education and HIV prevention needs, and they provided actionable recommendations to optimize its use and applicability for this age group.

Understanding HIV risk and vulnerability among cisgender men with transgender partners

In the HIV pandemic, cisgender (ie, non-transgender) men with transgender partners are an underserved population. Complexities of sexuality and gender affect HIV vulnerability for this group, including not identifying with conventional sexual orientation categories (eg, bisexual, heterosexual, or gay) and having attractions based on gender role or expression rather than genital anatomy. Only one HIV prevention interventional study in this population was identified, and one study that assessed the perceived acceptability of an intervention. We found no data for interventions using pre-exposure prophylaxis, interventions for cisgender men with transgender men partners, or cisgender men with casual or transactional sexual partnerships with transgender people. Cisgender men with transgender partners are not easily categorised using traditional HIV risk categories. Additional research is needed to understand stigma and other structural drivers of HIV vulnerability, sexual networks and practices, substance use patterns, and biomedical prevention interest and uptake for this group. Studies that use an intersectional lens and syndemic framework could offer key insights.

Gender Identity and Sexual Orientation in Chinese Men Who Have Sex with Men: A Latent Class Analysis

Men who have sex with men (MSM) are a diverse population yet are often treated as a monolithic risk group. In China, MSM have long been characterized as a "bridge population" of closeted men who are married to (or will marry) women due to sociocultural expectations. Latent class models can inform a more nuanced yet empirical characterization of this population. In total, 1424 eligible respondents recruited online provided self-reported behavioral data. Nine items related to constructs including sexual behaviors, sexual orientation, and gender identity informed the latent class model. Logistic regression was used to measure associations between latent class membership and HIV-related sexual and health-seeking behaviors. Model fit indicated a population structure made up of four classes that we characterized as "Gender nonconforming" (4.3%), "Closeted-unmarried" (29.9%), "Closeted-married" (24.6%), and "Out" (41.2%). Members of the "gender nonconforming" class were more likely to report HIV-related risk behaviors, and "Closeted-unmarried" class members were less likely to report health-seeking behaviors, both relative to "Out" members. The largest latent class was made up of members of the "Out" class, an enlightening revision of a population traditionally viewed as largely closeted men. Two types of "closeted" classes emerged, distinguished by divergent tendencies regarding marriage and health seeking. Findings suggest that current understandings of Chinese MSM are simplistic (regarding closeted behaviors) and too narrow (in its definition of MSM as cisgender men). A more nuanced understanding of MSM subgroups and their heterogeneous risk behaviors will be critical for provision of more meaningful prevention services.

Telemedicine: a solution to disparities in human immunodeficiency virus prevention and pre-exposure prophylaxis uptake, and a framework to scalability and equity

As the group with the highest risk and the lowest pre-exposure prophylaxis (PrEP) utilization, black and Hispanic young men who have sex with men (MSM) face the brunt of the current human immunodeficiency virus (HIV) epidemic within the United States. In this narrative review, we summarized recent interventions that utilize technology (telemedicine) to improve HIV PrEP uptake. We examined the general model of those telemedicine programs and evaluated their success and limitations in addressing PrEP accessibility for at-risk individuals. We also identified the current bottlenecks in the scalability of telemedicine programs, offered suggestions to overcome these barriers, and advocated for a centralized source of funding to increase the accessibility of telemedicine programs for PrEP.

Sexual risk-taking and subcortical brain volume in adolescence

Background

The developmental period of adolescence marks the initiation of new socioemotional and physical behaviors, including sexual intercourse. However, little is known about neurodevelopmental influences on adolescent sexual decision-making.

Purpose

We sought to determine how subcortical brain volume correlated with condom use, and whether those associations differed by gender and pubertal development.

Methods

We used FreeSurfer to extract subcortical volume among N = 169 sexually experienced youth (mean age 16.07 years; 31.95% female). We conducted multiple linear regressions to examine the relationship between frequency of condom use and subcortical volume, and whether these associations would be moderated by gender and pubertal development.

Results

We found that the relationship between brain volume and condom use was better accounted for by pubertal development than by gender, and moderated the association between limbic brain volume and condom use. No significant relationships were observed in reward areas (e.g., nucleus accumbens) or prefrontal cortical control areas.

Conclusions

These data highlight the potential relevance of subcortical socioemotional processing structures in adolescents' sexual decision-making.

We are delighted to share with you the views of some international opinion leaders on what the future may hold and what challenges lie ahead. In this issue of the Journal, authors describe current HIV and STI incidence among GBM and predict the future.

The relationship between stigma, family acceptance, peer support and stress level among HIV-positive men who have sex with men (MSM) in Medan, North Sumatera, Indonesia

OBJECTIVE

This present study investigates the level of stress and its relationship with stigma, family acceptance, and peer support among 176 HIV-positive MSM in Medan, Indonesia.

METHOD

This cross-sectional study with chi-square analysis was conducted April 2018 through May 2018 in Medan. The sample of this study were general HIV patients who identified themselves as MSM, were >18 years old, and were able to read and write in Indonesian. Data collection was conducted at Dr. H. Adam Malik Medan Hospital, Pirngadi General Hospital, Padang Bulan, and Teladan Kota Medan Health Center.

RESULTS

Findings show that 55.1% of the participants had severe stress. The results of this statistic showed that only stigma was positively associated with stress (p=0.049).

CONCLUSIONS

The results suggested that there is a need to reduce HIV stigma in reducing stress levels among HIV-positive MSM. Specific intervention should be designed for this population and integrated into programs to reduce stress levels.

Acceptability and feasibility of using digital vending machines to deliver HIV self-tests to men who have sex with men

OBJECTIVE

Technology-based approaches to distribute HIV self-tests (HIVST) have the potential to increase access to HIV testing in key populations. We evaluate the acceptability and feasibility of using vending machines (VMs) in a community setting to distribute HIVST to men who have sex with men at high-risk of HIV.

METHODS

First, a predevelopment survey of targeted potential users explored attitudes towards HIVST and the use of a VM to deliver HIVST. Second, participatory design workshops between designers and community volunteers informed the production of a bespoke VMs dispensing free BioSureHIVST. Uptake of HIVST and user experiences were evaluated using information supplied directly from the machines interface (number of tests dispensed, user demographics), an online questionnaire and semistructured interviews.

RESULTS

The predevelopment survey found that 32% of 232 sauna users had never tested for HIV, despite high-risk behaviours. A total of 265 testing kits were dispensed: mean age 31 range (18-70); 4%(n = 7) had never tested for HIV before and 11% (n = 22) had tested within the last 1-5 years. Uptake of tests was significantly higher via the VMs compared with outreach testing by community workers in the same venue during a comparable period (34 vs 6 tests per month). Qualitative interviews and online questionnaires demonstrated high acceptability for this intervention, which was considered accessible and appropriately targeted.

CONCLUSIONS

VMs to distribute HIVST was feasible and acceptable. This intervention could be used in different settings to improve access to HIV testing for key populations.

HIV continues to spread among men who have sex with men in Georgia; time for action

INTRODUCTION

In order to determine the impact of HIV prevention and care programs, it is essential to look at both HIV incidence and prevalence estimates and trends over time. We estimated the HIV incidence and prevalence and assessed the trend using data from three cross-sectional surveys of men who have sex with men (MSM) in two cities in Georgia.

METHODS

Using respondent-driven sampling strategy, a total of 796 eligible MSM (18 years or older men with self-reported oral or anal sex with another man in past 12 months) were recruited in Tbilisi in 2010, 2012 and 2015 and 115 in Batumi 2015 into behavioral surveys and HIV testing. To estimate the HIV incidence, we divided the number MSM tested positive for HIV to the time at risk. We calculated the time at risk as years since age at first anal intercourse to the age at last HIV-negative test or the age at first HIV-positive test, accounted for the interval censorship. We calculated the respondent-driven sampling adjusted estimates for HIV prevalence and assessed the trend in Tbilisi by Chi2 test for trend. For HIV incidence rate, we used Kaplan Meier method to estimate the rates and assessed the subgroup differences by log-rank test.

RESULTS

The HIV prevalence was 14.9% in Batumi in 2015; it significantly increased in Tbilisi from 6.2% in 2010 to 14.1% in 2012, and to 19.6% in 2015 (p-value for trend < 0.001). Likewise, the HIV incidence rate in Tbilisi significantly increased form 0.45 per 100 person-years (PY) in 2010 to 0.98 per 100 PY in 2012 (p-value 0.01), and to 1.63 per 100 PY in 2015 (p-value < 0.001). HIV incidence rate was 1.37 per 100 PY in Batumi in 2015. In 2015, young MSM (Tbilisi: 3.71, Batumi: 3.92 per 100 PY, p-value< 0.008), single MSM (Tbilisi: 1.99, per 100 PY, p-value 0.03) and less educated MSM (Batumi: 1.86 per 100 PY, p-value 0.03) had higher HIV incidence than other MSM.

CONCLUSION

Our findings suggest the continuous transmission of HIV among MSM in Tbilisi and a high prevalence of HIV among MSM in Batumi and the critical need for scaling up the coverage and accessibility of combination prevention packages including rapid HIV diagnosis and treatment.

Missed opportunities of HIV pre-exposure prophylaxis in France: a retrospective analysis in the French DAT'AIDS cohort

BACKGROUND

HIV pre-exposure prophylaxis (PrEP) was implemented in France in November 2015 based on individual-level risk factors for HIV infection. We evaluated the proportion of missed opportunities for PrEP among newly HIV-diagnosed people entering the Dat'AIDS cohort in 2016.

METHODS

Multicenter retrospective analysis in 15 French HIV clinical centers of patients with a new diagnosis of HIV infection. Among them we differentiated patients according to the estimated date of infection: those occurring in the PrEP area (a previous negative HIV test in the last 12 months or those with an incomplete HIV-1 western blot (WB) with no HIV-1 anti-Pol-antibody at time of HIV diagnosis) and those in the pre-PrEP area (older infections). Epidemiological, biological and clinical data at HIV diagnosis were collected. Clinicians retrospectively identified potential eligibility for PrEP based on individual-level risk factors for HIV infection among those infected in the PrEP area.

RESULTS

Among 966 patients with a new HIV diagnosis, 225 (23.3%) were infected in the PrEP area and 121 (53.8%) had complete data allowing evaluation of PrEP eligibility. Among them, 110 (91%) would have been eligible for PrEP, median age 31 years, with 68 (75.6%) born in France and 10 (11.1%) in Central/West Africa, with more than one previous STI in 19 (15.7%). The main eligibility criteria for PrEP were being a man who had sex with men or transgender 91 (82.7%) with at least one of the following criteria: unprotected anal sex with ≥2 partners in the last 6 months: 67 (60.9%); bacterial sexually transmitted infection in the last 12 months: 33 (30%); Use of psychoactive substances in a sexual context (chemsex): 16 (14.5%). PrEP was indicated for other HIV risk factors in 25 (22.7%).

CONCLUSION

With 91% (110/121) of patients infected in the PrEP area eligible for PrEP, this study highlights the high potential of PrEP in avoiding new infection in France but also shows a persistent delay in HIV testing. Thus, an important limit on PrEP implementation in France could be insufficient screening and care access.

Bayesian Estimation of MSM Population Size in Côte d'Ivoire

Côte d'Ivoire has among the most generalized HIV epidemics in West Africa with an estimated half million people living with HIV. Across West Africa, key populations, including gay men and other men who have sex with men (MSM), are often disproportionately burdened with HIV due to specific acquisition and transmission risks. Quantifying population sizes of MSM at the subnational level is critical to ensuring evidence-based decisions regarding the scale and content of HIV prevention interventions. While survey-based direct estimates of MSM numbers are available in a few urban centers across Côte d'Ivoire, no data on MSM population size exists in other areas without any community group infrastructure to facilitate sufficient access to communities of MSM. The data are used in a Bayesian regression setup to produce estimates of the numbers of MSM in areas of Côte d'Ivoire prioritized in the HIV response. Our hierarchical model imputes missing covariates using geo-spatial information and allows for proper uncertainty quantification leading to confidence bounds for predicted MSM population size estimates. This process provided population size estimates where there are no empirical data, to guide the prioritization of further collection of empirical data on MSM and inform evidence-based scaling of HIV prevention and treatment programs for MSM across Côte d'Ivoire.

Awareness of, interest in, and willingness to pay for HIV pre-exposure prophylaxis among Canadian gay, bisexual, and other men who have sex with men

OBJECTIVES

Pre-exposure prophylaxis (PrEP) is a highly effective, HIV prevention strategy increasingly being accessed by gay, bisexual, and other men who have sex with men (GBMSM). GBMSM face structural and individual-level barriers accessing PrEP, including awareness and cost. This paper assesses socio-demographic factors associated with awareness, interest, and willingness to pay for PrEP in a sample of Canadian GBMSM.

METHODS

Data were derived from the 2015 Sex Now survey, a cross-sectional, online survey of GBMSM. Respondents were recruited through social media, sex-seeking "apps," and by word of mouth. We used univariable and multivariable logistic regression models to estimate associations between socio-demographic factors and three primary outcomes.

RESULTS

Our sample consisted of 7176 HIV-negative Canadian GBMSM. Of respondents, 54.7% were aware of PrEP, 47.4% were interested in PrEP, and 27.9% of PrEP-interested respondents reported they would pay for PrEP out-of-pocket. Awareness and interest varied between provinces, while GBMSM outside urban areas were less likely to be PrEP aware. Bisexual-identified men, and men over 50, were less likely to be aware and interested in PrEP in multivariable models. Only annual income and educational attainment were associated with willingness to pay for PrEP.

CONCLUSION

This study identifies important disparities in awareness, interest, and willingness to pay for PrEP. Future interventions and educational efforts should target non-gay-identified and older GBMSM, as well as GBMSM outside urban areas. PrEP implementation may risk further perpetuating existing health inequities based on socio-economic status if PrEP continues to be accessed primarily through private insurance or paid for out-of-pocket.

A Qualitative Study of Young Men Who Have Sex With Men and Multilevel Factors Related to HIV Risks in Malaysia

Young men who have sex with men (YMSM) are a group at high risk for HIV infection, yet no research has been conducted to understand this population in Malaysia. Semistructured interviews from a combination of YMSM aged 18-25 (n = 20) and local service providers of sexual health services (n = 4) were conducted from May to June 2015. Thematic analysis was used to identify common themes in participant responses from transcripts. Participants reported societal and internalized homophobia, an absence of sex education and difficulty accessing confidential HIV testing. This study provides insights into how homophobia in Malaysian society influences individual risk behavior for HIV in Malaysian YMSM, and makes practical suggestions for more effective HIV prevention in this population.

Recent mobile health interventions to support medication adherence among HIV-positive MSM

PURPOSE OF REVIEW

We describe recent mobile health (mHealth) interventions supporting antiretroviral therapy (ART) medication adherence among HIV-positive MSM.

RECENT FINDINGS

Keyword searches (1 January 2016-13 May 2017) identified 721 citations. Seven publications reporting on six studies met inclusion criteria. Five studies focused on MSM. Interventions primarily employed text messaging (n = 4), whereas two focused on smartphone apps and one on social media. Three studies measured intervention impact on adherence and found increased ART use intentions (n = 1), self-reported adherence (n = 1), and viral suppression (n = 1, no control group). Other mHealth interventions for HIV-positive MSM focused on status disclosure and reducing sexual risk.

SUMMARY

mHealth interventions to support ART adherence among MSM show acceptability, feasibility, and preliminary efficacy. No recent mHealth interventions for MSM measured impact on viral suppression compared with a control condition despite earlier (pre-2015) evidence for efficacy. Studies are underway that include multiple features designed to improve adherence within complex smartphone or internet-based platforms. Areas for future growth include overcoming measurement and engagement challenges, developing tools for coordinating patient and provider adherence data, testing combination interventions, and adapting efficacious interventions for new languages and geographic settings.

Using technology to support HIV self-testing among MSM

PURPOSE OF REVIEW

Technology-based HIV self-testing (HST) interventions have the potential to improve access to HIV testing among gay, bisexual, and other MSM, as well as address concerns about HST use, including challenges with linkage to appropriate follow-up services. This review examines studies that use technology-based platforms to increase or improve the experience of HST among MSM.

RECENT FINDINGS

Seven published studies and eight funded studies were included in this review. Comprehensive prevention interventions with free HST kit distribution and interventions that provide free HST kits and support the HST process address a greater number of barriers (e.g., access, correct use of testing kits, and correct interpretation of results) than studies that only distribute free HST kits through technology-based platforms.

SUMMARY

By addressing HIV-testing barriers and specific HST concerns, these interventions address a critical need to improve first time and repeat testing rates among MSM. Additional research is needed to determine the efficacy of recent formative HST interventions. If proven efficacious, scale-up of these strategies have the potential to increase HIV testing among MSM via expanded HST uptake.

Potential Impact of Integrated Stigma Mitigation Interventions in Improving HIV/AIDS Service Delivery and Uptake for Key Populations in Senegal

BACKGROUND

Men who have sex with men (MSM) and female sex workers (FSW) are consistently shown to have a higher burden of HIV compared with other adults in Senegal. This study, HIV Prevention 2.0, evaluates the impact of the 3-tiered integrated stigma mitigation interventions (ISMIs) approach to optimizing HIV service delivery for key populations in Senegal.

METHODS

Baseline assessment includes a questionnaire and biological testing for HIV. A proportion of participants enrolled into a 24-month longitudinal cohort with questionnaires and biological testing every 3 months. In these preliminary analyses, ISMIs are evaluated from participants in the cohort through uptake of HIV services and implementation outcomes.

RESULTS

Overall, 724 MSM and 758 FSW participated in the baseline assessment. HIV prevalence is 30.2% (n = 219/724) among MSM and 5.3% (n = 40/758) among FSW. Fear of seeking health services among MSM is 17.7% (n = 128/724) at baseline, 10.5% (n = 18/172) at month 3, and 9.8% (n = 10/102) at month 6 (P < 0.004); and among FSW is 21.9% (n = 166/758) at baseline, 8.1% (n = 15/185) at month 3, and 10.7% (n = 18/168) at month 6 (P < 0.001). Overall, 63.9% (n = 62/97) of MSM and 82.5% (n = 118/143) of FSW agreed that the intervention is effective in addressing stigma; however, loss to follow-up was 41.1% among MSM and 10% among FSW.

CONCLUSION

Baseline data reinforce the need for stigma mitigation interventions, combined with enhanced linkage and retention to optimize HIV treatment. Preliminary results show high levels of HIV-related risk determinants and suggest the potential utility of the ISMI to decrease perceived stigma relating to engagement in HIV prevention, treatment, and care services among key populations in Senegal.
