Comparison of the prevalence rates of HIV infection between men who have sex with men (MSM) and men in the general population in sub-Saharan Africa: a systematic review and meta-analysis

Interest in I-PrEP and Willingness to Participate in Clinical Trials Among Men and Transfeminine Persons Who have Sex with Men in Sub-Saharan Africa: Quantitative and Qualitative Findings from HPTN 075

This study explored interest in injectable PrEP (I-PrEP) and willingness to participate in clinical trials testing new biomedical HIV prevention strategies among men and transfeminine persons who have sex with men (MSM & TGP), using data collected in the HIV Prevention Trials Network (HPTN) 075 study, which took place at sites in Kenya, Malawi, and South Africa. Data result from a survey among 267 18-44 years old HIV negative participants, complemented with semi-structured interviews with 80 purposively recruited persons. Correlations coefficients were calculated to identify demographic and psychosocial factors associated with interest in I-PrEP. Qualitative interviews were analyzed using concept-driven and subsequent data-driven coding. Most surveyed participants expressed an interest in I-PrEP. Quantitatively, only being interested in other HIV prevention measures was associated with interest in I-PrEP. Qualitatively, most participants preferred I-PrEP to O-PrEP and remained interested in I-PrEP despite barriers such as the somewhat invasive nature of the procedure and potential side effects of I-PrEP. Interest in I-PrEP was driven by the possibility of avoiding sexual or HIV stigma. Access to healthcare and altruism-such as assisting in the development of new HIV prevention methods-positively impacted willingness to participate in clinical trials. With I-PrEP favored by most participants, it is potentially a critical tool to prevent HIV infection among MSM & TGP in sub-Saharan Africa, with the mitigation of stigma as a major advance. Recruitment of MSM & TGP in biobehavioral clinical trials seems feasible, with altruistic reasons and receiving I-PrEP and free medical care as major motivators.

Disparities in mortality trends of adults with HIV in the USA: A comprehensive examination across 2 decades

Approximately 38 million people worldwide are affected by human immunodeficiency virus (HIV), with 4000 new infections daily. While literature explores HIV mortality among the elderly in the US, there is an underrepresentation of mortality data for adults. By scrutinizing mortality trends based on demographic factors such as gender, race or ethnicity, age groups, and geographic location, the study seeks to uncover patterns that may facilitate a longitudinal perspective for tailoring interventions and allocating resources effectively. Crude death rates and age-adjusted mortality rates (AAMR) per 100,000 individuals were calculated using HIV mortality data (ICD-10 Codes B20-24) from CDC WONDER database. Permutation test was used to calculate annual percentage changes in AAMR with 95% confidence interval. Average annual percentage changes were computed as weighted average of annual percentage changes. Between 1999 to 2020, US adult HIV deaths totaled 225,396 (AAMR: 5.03), with a significantly decreasing average annual percentage changes (-5.94). Males exhibited a 3-fold higher AAMR (7.50) than females (2.67). Non-Hispanic Blacks had the highest AAMR (21.82), while Non-Hispanic Asians had the lowest (0.67). The South and Northeast regions had the highest AAMRs (6.91 and 6.33, respectively). Notably, the District of Columbia had an alarmingly high mortality rate of 39.9, while North Dakota had the lowest (0.7). Urban regions (5.47) had double the mortality rates of rural regions (2.70). Mortality rate peaked in age groups 45 to 54 (8.65) and 35 to 44 (7.42). While overall HIV mortality is declining, disparities persist among demographics. Targeted interventions are crucial to improve preventive measures and healthcare access for disproportionately affected groups.

Stigmatizing clinical setting erodes physician-patient interaction quality for sexual minority men through perceived HIV stigma and HIV infection concerns in Zambia

This study investigated whether perceived HIV stigma and HIV infection concerns among healthcare providers (HCPs) mediate the association between stigmatizing clinical setting and their interaction quality with sexual minority men (SMM) patients in Zambia. In 2021, a cross-sectional survey was conducted with 91 HCPs offering HIV-related services to SMM in Zambia. Path analysis was conducted to examine the potential mediation effect of "perceived HIV stigma" and "HIV infection concern" among HCPs in the association between "stigmatizing clinical setting" and their "interaction quality with SMM". Mediators i.e., "perceived HIV stigma" and "HIV infection concern" among HCPs, were associated positively with the stigmatizing clinical setting (β = 0.329, p < .01, β = 0.917, p < 0.01), and negatively with physician-patient interaction quality (β = -0.167, p = 0.051; β = -0.126, p < 0.05). Stigmatizing clinical setting had a significant and negative indirect effect on HCPs interaction quality with SMM through increased perceived HIV stigma (z = -1.966, p < 0.05) and increased HIV infection concern (z = -1.958, p = 0.050). To improve physician-patient interaction quality, stigma reduction interventions among HCPs, who serve SMM in Zambia, should target development of development of inclusive policies and the cultivation of cultural norms that are supportive and respectful to SMM, and protection of HCPs from enacted stigma due to offering care to SMM.

Measuring intersectional HIV, sexual diversity, and gender non-conformity stigma among healthcare workers in Ghana: scale validation and correlates of stigma

BACKGROUND

Men who have sex with men (MSM) are at heightened risk for HIV acquisition, yet they may delay or avoid HIV testing due to intersectional stigma experienced at the healthcare facility (HCF). Few validated scales exist to measure intersectional stigma, particularly amongst HCF staff. We developed the Healthcare Facility Staff Intersectional Stigma Scale (HCF-ISS) and assessed factors associated with stigma in Ghana.

METHODS

We analyzed baseline data from HCF staff involved in a study testing a multi-level intervention to reduce intersectional stigma experienced by MSM. Data are from eight HCFs in Ghana (HCF Staff n = 200). The HCF-ISS assesses attitudes and beliefs towards same-sex relationships, people living with HIV (PLWH) and gender non-conformity. Exploratory factor analysis assessed HCF-ISS construct validity and Cronbach's alphas assessed the reliability of the scale. Multivariable regression analyses assessed factors associated with intersectional stigma.

RESULTS

Factor analysis suggested an 18-item 3-factor scale including: Comfort with Intersectional Identities in the Workplace (6 items, Cronbach's alpha = 0.71); Beliefs about Gender and Sexuality Norms (7 items, Cronbach's alpha = 0.72); and Beliefs about PLWH (5 items, Cronbach's alpha = 0.68). Having recent clients who engage in same-gender sex was associated with greater comfort with intersectional identities but more stigmatizing beliefs about PLWH. Greater religiosity was associated with stigmatizing beliefs. Infection control training was associated with less stigma towards PLWH and greater comfort with intersectional identities.

CONCLUSIONS

Achieving the goal of ending AIDS by 2030 requires eliminating barriers that undermine access to HIV prevention and treatment for MSM, including HCF intersectional stigma. The HCF-ISS provides a measurement tool to support intersectional stigma-reduction interventions.

Associations between Social Capital and Self-Rated Health among Men Who Have Sex with Men in Japan

Men who have sex with men (MSM) are significantly more likely to report poor health compared to the general population in Japan and internationally. Social capital has been observed as an important component of positive health and well-being outcomes among MSM. However, there is limited research investigating how alter sexuality (possessors of actual resources embedded in social capital networks) mitigates health outcomes. In an online survey of 1564 MSM in Japan, we investigated social correlates of poor self-rated health among MSM, including MSM and heterosexual social networks. Multiple logistic regression revealed that poor health was associated with older age, lower education, and part-time and unemployment. Poor health was inversely correlated with bisexual behavior and high MSM or heterosexual social capital. In order to decrease health disparities among MSM in Japan, interventions focusing on increasing social capital among deprived groups, such as those with lower socio-economic status, older MSM, and those whose sex partners are exclusively male, may be effective.

Physician-Patient Interaction Quality Mediates the Association Between HIV-Related Stigma and HIV-Prevention Behaviors Among Sexual Minority Men in Zambia

HIV-related stigma is a major challenge to HIV prevention for sexual minority men (SMM) in Zambia, but little is known about the underlying mechanisms. This study aimed to investigate whether physician-patient interaction quality mediates the relationship between HIV-related stigma and HIV-prevention behaviors among SMM. Data were collected using a cross-sectional survey from 194 SMM (aged: mean = 24.08, SD = 4.27) across four districts in Zambia between February and November 2021. Participants were asked about their demographic characteristics, HIV-related stigma, SMM-related stigma, physician-patient interaction quality, HIV-testing intention, and use of pre-exposure prophylaxis (PrEP). Path analysis was used to test the mediation effect of physician-patient interaction quality in the associations of HIV-related stigma/SMM-related stigma with HIV-testing intention and current PrEP use. Higher self-reported physician-patient interaction quality was negatively associated with HIV-related stigma (β = - 0.444, z = - 2.223, p < 0.05), and positively associated with HIV-testing intention (β = 0.039, z = 5.121, p < 0.001) and current PrEP use (β = 0.008, z = 2.723, p < 0.01). HIV-related stigma among SMM had a significant and negative indirect effect on HIV-testing intention (β = - 0.017, z = - 2.006, p < 0.05), and current PrEP use (β = - 0.004, z = - 2.009, p < 0.05) through physician-patient interaction quality. Contrary to our expectations, SMM-related stigma did not have a significant and negative indirect effect on HIV prevention behaviors through physician-patient interaction quality. Health interventions need to improve physician-patient interaction quality by offering healthcare provider training, targeting HIV-related stigma in healthcare settings, and devising inclusive healthcare policies to promote HIV prevention efforts.

Extragenital Sexually Transmitted Infections Among High-Risk Men Who Have Sex With Men in Johannesburg, South Africa

BACKGROUND

In South Africa, extragenital etiological sexually transmitted infection (STI) screening among men who have sex with men (MSM) is not routinely available. We aimed to determine the prevalence of STI pathogens at rectal and pharyngeal sites, syphilis seroprevalence, and associated risk factors among a selection of high-risk MSM without symptomatic urethritis attending a men's health clinic in Johannesburg, South Africa.

METHODS

A cross-sectional study was conducted in 2022. Enrolled clients self-reported demographic, sexual behavioral risks, and clinical information. Client or clinician-collected rectal and pharyngeal swabs were tested for Neisseria gonorrhoeae, Chlamydia trachomatis, Mycoplasma genitalium, and Trichomonas vaginalis. C. trachomatis-positive rectal samples were reflex tested for lymphogranuloma venereum. Blood specimens were screened for syphilis. Univariate and multivariate regression models were used to determine factors independently associated with the presence of an extragenital STI or syphilis.

RESULTS

Among the 97 participants (median age, 29 years), 24.7% had an extragenital STI and 9.4% had high nontreponemal antibody titers (rapid plasma reagin ≥1:16). Rectal STIs were detected in 26.4% participants: N. gonorrhoeae (14.3%), C. trachomatis (9.9%), and M. genitalium (5.5%). Pharyngeal STIs were less prevalent (4.1%). Overall, the prevalence of any STI was 41%. Sex under the influence of drugs (adjusted odds ratio, 4.94; 95% confidence interval, 1.56-15.69) and engaging in condomless receptive anal intercourse with a casual partner (adjusted odds ratio, 8.36; 95% confidence interval, 1.73-40.28) were independent risk factors for having an extragenital STI.

CONCLUSIONS

The high burden of extragenital STIs and active syphilis in asymptomatic MSM underscores the importance of routine etiological screening in this key population, as the syndromic approach would not enable detection or treatment of these infections.

Awareness and willingness to use pre-exposure prophylaxis for HIV prevention among men who have sex with men in Rwanda: findings from a web-based survey

Introduction

Pre-exposure Prophylaxis (PrEP) is a daily pill aimed at reducing HIV transmission risk when taken as prescribed. It's highly recommended for high-risk Men who have sex with Men (MSM). This study aimed to assess PrEP awareness and willingness to use it among Rwandan MSM, a critical aspect given PrEP's proven effectiveness. The findings are expected to inform policy decisions and further advance the implementation of PrEP strategies.

Methods

This is a cross-sectional study design that utilized a web-based survey conducted between April and June 2019 to assess awareness and willingness to use PrEP among sexually active MSM in Rwanda. A snowball sampling technique was used to recruit participants via social media such as WhatsApp and e-mail. Eligibility criteria included being sexually active, aged ≥18 years, self-identifying as MSM, residing in Rwanda, self-reported engagement in receptive or insertive anal sex in the last 12 months, and self-reported HIV-negative serostatus. We assessed two primary outcomes: PrEP awareness (having ever heard of PrEP) and willingness to use PrEP within one month of completing the survey. Multivariable logistic regression was performed to identify participant characteristics associated with PrEP awareness and willingness to use it.

Results

Out of 521 participants, the majority (73%) demonstrated awareness of PrEP. Factors linked to PrEP awareness included residing outside the capital, Kigali, being in the 18-29 age group, having higher education levels, perceiving a benefit from PrEP, and engaging in vaginal sex with a woman while using a condom in the last year. Additionally, 96% of participants expressed a strong willingness to use PrEP.

Conclusion

Rwandan MSM exhibits a high level of PrEP awareness, notably associated with factors like location, age, education, perceived benefits, and condom use. The study also revealed a strong willingness to use PrEP, indicating promising prospects for its adoption among this group. These findings highlight the need for targeted awareness campaigns, personalized interventions, and comprehensive sexual health education to promote PrEP adoption and strengthen HIV prevention efforts among Rwandan MSM.

Association of same-sex criminalisation laws and national HIV policies with HIV testing in African MSM: an ecological single-level and multilevel cross-sectional study of sub-Saharan African countries

BACKGROUND

HIV incidence among men who have sex with men (MSM) in sub-Saharan Africa (SSA) remains high compared with the general population. Many countries in the region still criminalise consensual homosexual relationships, and some are yet to adopt WHO-recommended interventions for MSM into national HIV policies. This study examines how HIV testing of adult MSM in SSA varies according to the legal climate and presence of targeted HIV policy using data from the cross-sectional 2019 Global LGBTI Internet Survey study.

METHODS

Using data from 3191 MSM in 44 SSA countries, we assessed associations of legal climate and HIV policy with ever and recent HIV testing using linear ecological and logistic multilevel analyses. From the single-level analysis, we can compare our findings to previously reported data, then, extending to a two-level multilevel analysis, we account for the hierarchical structure of the population and simultaneously adjust for differences in context and composition in each country. We then test the sensitivity of our analyses to excluding countries from the model.

RESULTS

We find evidence that legalised same-sex relationships were associated with increased odds of ever testing (OR=2.00, 95% CI 1.04, 3.82) in multilevel analyses. We also find evidence of an association of targeted HIV policies with increased odds of ever testing (OR=2.49, 95% CI 1.12, 5.52). We did not find evidence of an association of the legal climate (OR=1.01, 95% CI 0.69, 1.46) and targeted HIV policies (OR=1.26, 95% CI 0.78, 2.04) with recent testing.

CONCLUSIONS

This study suggests elimination of discriminatory laws and policies might be important for increasing HIV status awareness of MSM, an important first step in epidemic control. Additionally, we highlight heterogeneity between South Africa and other SSA countries, which has implications for studying SSA countries as a homogeneous group.

Impact of enacted stigma on mental health, substance use, and HIV-related behaviors among sexual minority men in Zambia

Sexual minority men (SMM) in Zambia face significant challenges including stigma, discrimination, and mental health issues, which further impact their HIV-related risk behaviors. This study aimed to investigate the associations between enacted stigma, substance abuse, HIV-related behaviors, and mental health (i.e., depression, anxiety, and post-traumatic stress disorder [PTSD] symptoms) among SMM in Zambia. SMM aged 18-35 years who reported having multiple and/or concurrent sexual partners or low and/or inconsistent condom use in the past three months were recruited from four districts in Zambia between February and November 2021. Participants completed an anonymous interviewer-administered survey. Key variables of interest were compared between participants with higher vs. lower levels of enacted stigma. Independent samples t-tests were used for continuous variables, and chi-squared tests were used for categorical variables. A total of 197 eligible SMM participated in the study (mean age = 24.41 years). Participants with a higher level of enacted stigma showed a higher level of anxiety symptoms (χ2 = 12.91, p ≤ .001), PTSD symptoms (χ2 = 7.13, p < .01), tobacco use (χ2 = 10.47, p < .01), cannabis use (χ2 = 5.90, p < .05), and a higher number of sexual partners (t = 1.99, p < .05) in the past three months. Stigma reduction interventions may help mitigate substance abuse, HIV-related behaviors, and adverse mental health outcomes among SMM in Zambia. Health care providers, especially psychiatric-mental health nurses, can incorporate strategies for recognizing and addressing stigma into their practice through training and integrate multiple resources to create an inclusive and non-judgmental environment for SMM to improve their well-being.

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.

Is Internalised Homonegativity associated with HIV testing and HIV risk behaviours of men who have sex with men: a multilevel cross-sectional study of sub-Saharan African countries

OBJECTIVES

This study assessed the associations of Internalised Homonegativity (IH) with HIV testing and risk behaviours of adult men who have sex with men (MSM) in sub-Saharan Africa (SSA) and effect modification by the legal climate.

DESIGN

We used data from the cross-sectional 2019 Global Lesbian, Gay, Bisexual, Transgender and Intersex (LGBTI+) Internet survey study.

SETTING AND PARTICIPANTS

Overall, the 2019 Global LGBTI Internet Survey collected data from 46 SSA countries. In this secondary analysis, we included data from 3191 MSM in 44 SSA countries as there were no eligible MSM responses in the 2 countries excluded.

OUTCOME MEASURES

Our response variables were self-reported binary indicators of ever tested for HIV, recently tested in the past 6 months (from those who reported ever testing), transactional sex (paying for and being paid for sex in the past 12 months), and unprotected anal sex (that is without a condom or pre-exposure prohylaxis (PrEP)) with a non-steady partner (in the past 3 months).

RESULTS

Our findings showed high levels of IH (range 1-7) in MSM across SSA (mean (SD)=5.3 (1.36)). We found that MSM with higher IH levels were more likely to have ever (adjusted OR (aOR) 1.18, 95% CI 1.03 to 1.35) and recently tested (aOR 1.19, 95% CI 1.07 to 1.32) but no evidence of an association with paying for sex (aOR 1.00, 95% CI 0.89 to 1.12), selling sex (aOR 1.06, 95% CI 0.95 to 1.20) and unprotected sex (aOR 0.99, 95% CI 0.89 to 1.09). However, we observed that a favourable legal climate modifies the associations of IH and paying for sex (aOR 0.75, 95% CI 0.60 to 0.94). Increasing levels of IH had a negative association with paying for sex in countries where same-sex relationships are legal. We found no associations of IH with unprotected anal sex in the population surveyed.

CONCLUSIONS

We confirm that IH is widespread across SSA but in countries that legalise same-sex relationships, MSM were less likely to engage in transactional sex compared with those in countries where homosexuality is criminalised.

Distinct Rates and Transmission Patterns of Major HIV-1 Subtypes among Men who Have Sex with Men in Guangxi, China

The diversity and transmission patterns of major HIV-1 subtypes among MSM population in Guangxi remains unknown. Understanding the characteristics is crucial for effective intervention strategies. Between 2016 and 2021, we recruited individuals newly diagnosed with HIV-1 from MSM population in Guangxi. HIV-1 pol region was amplified and sequenced, and constructed molecular network, assessed clustering rate, cluster growth rate, spatial clustering, and calculating the basic reproductive number (R0) based on sequences data. We identified 16 prevalent HIV-1 subtypes among Guangxi MSM, with CRF07_BC (53.1%), CRF01_AE (26.23%), and CRF55_01B (12.96%) predominating. In the network, 618 individuals (66.17%) formed 59 clusters. Factors contributing to clustering included age < 30 years (AOR = 1.35), unmarried status (AOR = 1.67), CRF07_BC subtype (AOR = 3.21), and high viral load (AOR = 1.43). CRF07_BC had a higher likelihood of forming larger clusters and having higher degree than CRF01_AE and CRF55_01B. Notably, CRF07_BC has higher cluster growth rate and higher basic reproductive number than CRF01_AE and CRF55_01B. Our findings underscore CRF07_BC as a prominent driver of HIV-1 spread among Guangxi's MSM population, highlighting the viability of targeted interventions directed at specific subtypes and super clusters to control HIV-1 transmission within this population.

Update on the M-pox virus and safety measures taken against it globally

Globally, more than 50 countries have been affected by Monkey pox virus after COVID-19 has subsided. WHO declared "public health emergency of international concern" in year 2022 because of virus affecting 60,000 people in just one month that belonged to clade-IIb. Previously, it had been transmitted by body fluids, lesions and touching items, but fresh transmission is via sexual activity among bisexuals and man to man sex (MSM). New outbreaks reported compromised health status of confirmed cases with rectal pain, bleeding, tenesmus, pus or blood in stool, vomiting, proctitis and abdominal pain, which became alarming for entire world because of complications leading to bacterial skin infections, sepsis, encephalitis, hemorrhagic disease, blindness and pneumonia eventually. This virus has been further deteriorating unstable and unsustainable economy that requires dire attention. Strict preventive measures in terms of personal hygiene, pet and livestock health care, hospital contaminant disposal, good surveillance record, pre and post exposure vaccination, waste and water management could be only possible strategies to eliminate devastatingly dangerous M-pox outbreaks in this epic.

HIV prevalence in transgender populations and cisgender men who have sex with men in sub-Saharan Africa 2010-2022: a meta-analysis

Introduction

The Global AIDS Strategy 2021-2026 calls for equitable and equal access to HIV prevention and treatment programmes for all populations to reduce HIV incidence and end HIV/AIDS as a public health threat by 2030. Transgender populations (TGP), including transmen (TGM) and transwomen (TGW) are populations that have been marginalised and are at high risk of HIV infection in sub-Saharan Africa (SSA). Limited surveillance data on HIV among TGP are available in the region to guide programmatic responses and policymaking. Surveillance data on cisgender men who have sex with men (cis-MSM) are comparatively abundant and may be used to infer TGP HIV prevalence.

Methods

Data from key population surveys conducted in SSA between 2010-2022 were identified from existing databases and survey reports. Studies that collected HIV prevalence on both TGP and cis-MSM populations were analysed in a random effect meta-analysis to estimate the ratio of cis-MSM:TGW HIV prevalence.

Results

Eighteen studies were identified encompassing 8,052 TGW and 19,492 cis-MSM. TGW HIV prevalence ranged from 0-71.6% and cis-MSM HIV prevalence from 0.14-55.7%. HIV prevalence in TGW was 50% higher than in cis-MSM (prevalence ratio (PR) 1.50 95% CI 1.26-1.79). TGW HIV prevalence was highly correlated with year/province-matched cis-MSM HIV prevalence (R2 = 0.62), but poorly correlated with year/province-matched total population HIV prevalence (R2 = 0.1). Five TGM HIV prevalence estimates were identified ranging from 1-24%. Insufficient TGM data were available to estimate cis-MSM:TGM HIV prevalence ratios.

Conclusion

Transgender women experience a significantly greater HIV burden than cis-MSM in SSA. Bio-behavioural surveys designed and powered to measure determinants of HIV infection, treatment coverage, and risk behaviours among transgender populations, distinct from cis-MSM, will improve understanding of HIV risk and vulnerabilities among TGP and support improved programmes.

The use of PrEP among men who have sex with men and transgender women as Biomedical Prevention Work: A conceptual framework

Based on ethnographic fieldwork among men who have sex with men and transgender women in Tanzania, this article explores the various types of work that may go into enrolment into PrEP programming and using pre-exposure prophylaxis (PrEP). PrEP protects against HIV acquisition and is widely touted as an essential tool in 'ending AIDS by 2030'. While taking PrEP has often been portrayed as 'just taking a pill a day' in public health campaigns, a striking observation during fieldwork was that enrolling in PrEP programming and adhering to PrEP involved a wide range of tasks. Inspired by this fieldwork experience and the literature on sociology of work, more specifically illness work and patient work, we started to think of these tasks as work. This paper identifies the range of tasks that PrEP users in Dar es Salaam had to perform as part of their enrolment and usage of PrEP. We provide a description of these tasks, organised into three categories of work that we refer to as (a) readying work, (b) user work, and (c) social navigation work that jointly make up what we propose to call biomedical prevention work. We further suggest that this analytical framework can be applicable to other biomedical prevention methods in other contexts.

Prevalence of gonococcal and chlamydial infections among men who have sex with men in sub-Saharan Africa: protocol for a systematic review and meta-analysis

BACKGROUND

Bacterial sexually transmitted infections (STIs) including Neisseria gonorrhoeae and Chlamydia trachomatis are common in men who have sex with men (MSM). These infections increase the risk of acquiring and transmitting human immunodeficiency virus (HIV) in this key population. Access to MSM in many countries in sub-Saharan Africa remains generally difficult due to discrimination or criminalization of their sexual orientation which could lead to depression and risky sexual practices associated with prevalence. This protocol therefore proposes to undertake a systematic review and meta-analysis of literature on the prevalence of gonococcal and chlamydial infections among MSM in Sub-Saharan Africa.

METHODS

This review which aims to ascertain the pooled prevalence and risk factors of these infections in sub-Saharan Africa's MSM population will follow the Preferred Reporting Items for Systematic Review and Meta-analyses (PRISMA) guidelines. The search strategy will review relevant articles from the following databases: PubMed, Scopus, ISI Web of Science and the Directory of Open Access Journals (DOAJ). Articles screening for eligibility and data extraction will be conducted by two independent reviewers. All discrepancies will be resolved by the third and fourth reviewers. Heterogeneity in studies will be evaluated using the I2 statistic and where heterogeneity is high and significant, a random effect model will be used to estimate the pooled prevalence. Publication bias will be assessed using the Doi plot. Extracted data will be analysed using MetaXL add-on for Microsoft excel. Data will be presented in tables and graphically presented in forest plots.

DISCUSSION

In this study, we anticipate being able to systematically determine the prevalence of Neisseria gonorrhoeae and Chlamydia trachomatis among MSM as well as explore possible risk factors associated with prevalence. The outcomes of the systematic review and meta-analyses will serve to support researchers and public health stakeholders in identifying healthcare priorities and in addressing issues pertaining to the overall wellbeing of the MSM community.

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

BACKGROUND

Gay, bisexual, and other men who have sex with men (MSM) are disproportionately affected by HIV. In Africa, MSM face structural barriers to HIV prevention and treatment that increase their vulnerability to HIV acquisition and transmission, and undermine the HIV response. In this systematic review, we aimed to explore progress towards increases in HIV testing, improving engagement in the HIV treatment cascade, and HIV incidence reductions among MSM in Africa.

METHODS

We searched Embase, MEDLINE, Global Health, Scopus, and Web of Science for cross-sectional and longitudinal studies reporting HIV testing, knowledge of status, care, antiretroviral therapy (ART) use, viral suppression, and HIV incidence among MSM in Africa published between Jan 1, 1980, and March 3, 2023. We pooled surveys using Bayesian generalised linear mixed-effects models, used meta-regression to assess time trends, and compared HIV incidence estimates among MSM with those of all men.

FINDINGS

Of 9278 articles identified, we included 152 unique studies published in 2005-23. In 2020, we estimate that 73% (95% credible interval [CrI] 62-87) of MSM had ever tested for HIV. HIV testing in the past 12 months increased over time in central, western, eastern, and southern Africa (odds ratio per year [ORyear] 1·23, 95% CrI 1·01-1·51, n=46) and in 2020 an estimated 82% (70-91) had tested in the past 12 months, but only 51% (30-72) of MSM living with HIV knew their HIV status. Current ART use increased over time in central and western (ORyear 1·41, 1·08-1·93, n=9) and eastern and southern Africa (ORyear 1·37, 1·04-1·84, n=17). We estimated that, in 2020, 73% (47-88) of all MSM living with HIV in Africa were currently on ART. Nevertheless, we did not find strong evidence to suggest that viral suppression increased, with only 69% (38-89) of MSM living with HIV estimated to be virally suppressed in 2020. We found insufficient evidence of a decrease in HIV incidence over time (incidence ratio per year 0·96, 95% CrI 0·63-1·50, n=39), and HIV incidence remained high in 2020 (6·9 per 100 person-years, 95% CrI 3·1-27·6) and substantially higher (27-199 times higher) than among all men.

INTERPRETATION

HIV incidence remains high, and might not be decreasing among MSM in Africa over time, despite some increases in HIV testing and ART use. Achieving the UNAIDS 95-95-95 targets for diagnosis, treatment, and viral suppression equitably for all requires renewed focus on this key population. Combination interventions for MSM are urgently required to reduce disparities in HIV incidence and tackle the social, structural, and behavioural factors that make MSM vulnerable to HIV acquisition.

HIV prevalence and associated risk factors among young tertiary student men who have sex with men (MSM) in Nairobi, Kenya: a respondent-driven sampling survey

BACKGROUND

Young men who have sex with men (MSM), are a key population at higher risk of HIV infection yet they are underrepresented in research. We conducted a bio-behavioral survey to estimate HIV prevalence and associated risk factors among tertiary student MSM (TSMSM) in Nairobi, Kenya.

METHODS

Between February and March 2021, 248 TSMSM aged ≥ 18 years who reported sex with another man in the past year participated in a respondent-driven sampling (RDS) based cross-sectional survey. Participants completed an electronically self-administered behavioral survey and provided a blood sample for HIV antibody testing, alongside urine, anorectal and oropharyngeal swabs for pooled testing of sexually transmitted infections using a multiplex nucleic acid amplification test. RDS-Analyst v.0.72 and Stata v.15 software were used for data analysis. Differences in proportions were examined using chi-square (χ²) test, and unweighted multivariate logistic regression was used to assess factors associated with HIV infection.

RESULTS

HIV prevalence among study participants was 8.3%, whereas the weighted prevalence was 3.6% (95% CI: 1.3-6.0%). Median ages of participants, and at self-reported first anal sex with a man were 21(interquartile range [IQR] 20-22) and 18 (IQR 17-19) years, respectively. A majority (89.3%) of TSMSM owned a smart phone, 46.5% had ever used a geosocial networking app for MSM such as Grindr ® to find a sex partner, and a third (33.6%) met their last sex partner online.  Almost three-quarters (71.3%) had > 1 male sex partner in the year before the survey. A third (34.3%) did not use condoms with their last sex partner, 21.2% received money from their last sex partner and 40.9% had taken alcohol/another drug during their last sexual encounter. HIV infection was associated with studying in private institutions (adjusted odds ratio[AOR] = 6.0; 95% confidence intervals [CI] : 1.2-30.0, p = 0.027), preferring a sex partner of any age-younger, same or older (AOR = 5.2; 95 CI: 1.1-25.2, p = 0.041), last sex partner being > 25 years (AOR = 6.4; 95% CI: 1.2-34.6, p = 0.030), meeting the last sex partner online (AOR = 4.2; 95% CI; 1.1-17.0, p = 0.043) and testing positive for Neisseria gonorrhea (AOR = 7.8; 95% CI: 2.0-29.9, p = 0.003).

CONCLUSIONS

HIV prevalence among TSMSM in Nairobi is alarmingly high, demonstrating a need for tailored prevention and control interventions for this young key population.

Epidemiologic Situation of HIV and Monkeypox Coinfection: A Systematic Review

The most recent monkeypox (Mpox) outbreak is mostly affecting men who have sex with men (MSM) who participate in high-risk sexual behaviors, which is typically the case among human immunodeficiency virus (HIV) carriers, according to clinical and epidemiological statistics. The objective of this research is to determine the epidemiological situation of HIV and smallpox co-infection. Until 1 October 2022, a thorough evaluation of the literature was conducted utilizing the databases PubMed, Embase, Scopus, and Web of Science. Studies were evaluated based on the criteria for selection. Fifty-three studies met the selection criteria. A total of 6345 confirmed cases of monkeypox were recorded, and 40.32% (n = 2558) of these cases also had HIV co-infection. In addition, 51.36% (n = 3259) of the men (91.44%; n = 5802), whose ages ranged from 18 to 71 years, exhibited MSM-specific sexual behaviors. Co-infection with these two viruses can be especially dangerous because it can exacerbate the symptoms of both diseases and make them more difficult to treat. People with HIV are more vulnerable to certain infections, including monkeypox, because their immune systems are weakened. Therefore, it is important that they take measures to prevent infection, such as avoiding contact with infected animals, risky behaviors, and maintaining good hygiene.

The Prevalence of Anxiety among Men Who Have Sex with Men: A Protocol for A Systematic Review and Meta-Analysis

Anxiety is reported to be common and serious among men who have sex with men (MSM). A growing number of researchers focus on MSM's anxiety and reported their severity, while the estimate results vary substantially between studies. The objective of this study is to evaluate the pooled prevalence of anxiety or anxiety disorders among MSM worldwide. This systematic review and meta-analysis protocol will follow the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA-P) guidelines. Studies will be searched from English and Chinese electronic databases. Observational studies, longitudinal studies, and controlled trials reporting the prevalence of anxiety or anxiety disorders among MSM will be included. Two reviewers will independently screen all the studies and extract data. Quality appraisal will be conducted using the Joanna Briggs Institute's (JBI's) critical appraisal checklist for reporting prevalence data. Meta-analysis will be implemented with a random-effect model which will evaluate pooled prevalence of anxiety with 95% confidence intervals (CI). Subgroup analysis will be conducted among different regions, sampling methods, data collection methods, MSM characteristics, measures used to assess anxiety and its cut-off. This review will contribute to a great understanding of anxiety among MSM worldwide. The findings will help relative policymakers and researchers develop effective measures and interventions for reducing the burden of anxiety morbidity among this population.

Planning for decentralized, simplified prEP: Learnings from potential end users in Ga-Rankuwa, gauteng, South Africa

Background

In South Africa, youth experience challenges with oral Pre-Exposure Prophylaxis (PrEP) access and uptake. Taking services out of healthcare settings has the potential to increase reach and overcome these challenges. This paper presents young and older people's preferences for decentralized, simplified PrEP service delivery and new long-acting HIV prevention methods, in Ga-Rankuwa, South Africa.

Methods

Between May and August 2021, both PrEP user and non-user adolescent girls and young women (AGYW), pregnant AGYW, female sex workers, adolescent boys and young men (ABYM), and men who have sex with men (MSM) were recruited to participate in focus group discussions (FDGs) in Ga-Rankuwa, Gauteng. Twenty-two FGDs were conducted. Participants were asked about PrEP uptake, potential acceptability of long-acting HIV prevention products, provision of integrated, simplified, and decentralized services, and digital tools to facilitate access to PrEP and other SRH services. A qualitative approach using inductive thematic analysis was carried out to explore emerging themes on decentralized, simplified delivery and the acceptability of long-acting methods.

Results

Of the 109 participants included in the study approximately 45% (n = 50) were female, the median age was 23 years ± 5.3. A third (n = 37) were current or previous PrEP users, of which, 59.5% (n = 22) collected PrEP refills from the clinic. Decentralized, simplified service delivery was appealing; health facilities, pharmacies and institutions of learning were preferred as service points for PrEP and SRH services, and recreational spaces preferred for dissemination of health information and engagement. ABYM were more open to having recreational spaces as service points. Long-acting Cabotegravir was preferred over the Dapivirine Vaginal Ring due to concerns around perceived side-effects, efficacy, and comfort.

Conclusion

Providing long-acting PrEP methods through decentralized, simplified service delivery was appealing to this population. They provided practical locations for decentralized service provision to potentially increase their engagement with and uptake of HIV prevention and SRH services.

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.

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.

They call us goor-jigeen: a qualitative exploration of the experiences of Senegalese Muslim men who have sex with men living with HIV

Men who have sex with men living with HIV in majority Muslim communities face discrimination based on multiple forms of stigma at socio-cultural and legislative levels. This study aimed to explore qualitatively the experiences of men who have sex with men living with HIV in Dakar, Senegal. In-depth individual interviews were conducted with 30 Senegalese men aged 18 to 55 years, who self-reported as same-sex practising, Muslim, and receiving HIV treatment at health centres in Dakar. Interview data were analysed using an ethnographic phenomenological approach to explore their life experiences. Primary themes included: the self-discovery process; the social, religious and health ramifications of being same-sex practising; and stigma. Within the theme of stigma issues described included shame, blame (of self and others), and violence resulting from being a man who has sex with other men and/or being HIV seropositive. Those with undetectable viral load reported how HIV related stigma and burden diminished as their health improved. Disclosure of being men who have sex with men and/or HIV status, whether voluntary or not, affected experiences of violence and/or isolation. Addressing stigma at healthcare institutions and improving access to HIV treatment can help mitigate the burden of stigma affecting such men. Interventions to address their physical and psychosocial wellbeing require the engagement of multiple stakeholders, including religious and political leaders.

Integrating HIV and mental health interventions to address a global syndemic among men who have sex with men

In this Series paper, we review evidence on the co-occurring and synergistic epidemics (syndemic) of HIV and mental health problems worldwide among men who have sex with men (MSM). The multilevel determinants of this global syndemic include structural factors that enable stigma, systematic bias, and violence towards MSM across geographical and cultural contexts. Cumulative exposure to these factors over time results in population-level inequities in the burden of HIV infections and mental health problems among MSM. Evidence for this syndemic among MSM is strongest in the USA, Canada, western Europe, and parts of Asia and Latin America, with emerging evidence from sub-Saharan Africa. Integrated interventions are needed to address syndemics of HIV and mental health problems that challenge the wellbeing of MSM populations worldwide, and such interventions should consider various mental health conditions (eg, depression, anxiety, trauma, and suicidality) and their unique expressions and relationships with HIV outcomes depending on cultural contexts. In addition, interventions should identify and intervene with locally relevant structural factors that result in HIV and mental health vulnerabilities among MSM.

Factors Associated with Unprotected Anal Sex among Men Who Have Sex with Men in Mexico

The global prevalence of HIV is notably higher in men who have sex with men (MSM) compared with other male populations. Unprotected anal intercourse is the riskiest sexual behavior for HIV acquisition and/or transmission among this minority population. The purpose of the study was to identify if the syndemic of psychosocial stressors and experienced stigma are predictors of unprotected anal sex in Mexican MSM. A cross-sectional analytic study was carried out. It included adults residing in Manzanillo, Mexico, with oral/anal sex practices within the last year. Informed consent was given by 142 participants selected using snowball sampling. Collected data included sociodemographic characteristics, psychosocial stressors, experienced stigma, HIV knowledge, knowing a friend/acquaintance living with HIV/AIDS, and sexual risk behaviors. Adjusted logistic regression was used to identify predictors of unprotected anal sex within the last six months. Presence of syndemic of psychosocial stressors, drug use during sex, having friends/acquaintances with HIV/AIDS, and experiencing high stigma were positively associated; high level of HIV knowledge was negatively linked. Reducing psychosocial stressors and integrating stigma-mitigation strategies are key elements to reduce HIV transmission.

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.

Stigma, Social Cohesion, and HIV Risk Among Sexual and Gender Minorities in Two Cities in Zimbabwe

Though stigma is a recognized contributor to the disproportionate HIV burden among sexual and gender minorities (SGM) in sub-Saharan Africa, data describing this association among Zimbabwean SGM are limited. We examined relationships between SGM stigma and HIV and the potential for social cohesion to moderate the association among Zimbabwean men who have sex with men, transgender women, and genderqueer individuals. Consenting participants (n = 1511) recruited through respondent-driven sampling for a biobehavioral survey in Harare and Bulawayo completed structured interviews and received HIV testing. Reported SGM stigma was common (68.9% in Harare and 65.3% in Bulawayo) and associated with HIV infection in Harare (adjusted prevalence ratio [aPR] = 1.82, 95% confidence interval [CI] = 1.27–2.62) and Bulawayo (aPR = 1.51, 95% CI = 1.15–2.00) in relative risk regression. Social cohesion did not moderate these relationships. Findings demonstrate stigma’s association with HIV vulnerability among Zimbabwean SGM, highlighting the need for stigma-mitigation to reduce HIV transmission in this population.

HIV care cascade and associated factors among men who have sex with men, transgender women, and genderqueer individuals in Zimbabwe: findings from a biobehavioural survey using respondent-driven sampling

BACKGROUND

Globally, men who have sex with men (MSM), transgender women, and genderqueer individuals are at greater risk for HIV than the general population although little data are available from these groups in Zimbabwe, a country with a national adult HIV prevalence of 12·9%. We aimed to examine progress towards the UNAIDS 90-90-90 treatment targets and factors associated with meeting the targets among a sample of MSM, transgender women, and genderqueer individuals in Zimbabwe.

METHODS

In this cross-sectional survey in 2019, we used respondent-driven sampling to identify MSM, transgender women, and genderqueer individuals aged at least 18 years to participate in a biobehavioural survey in Harare and Bulawayo, Zimbabwe. Participants were eligible to participate if they were assigned male at birth; had engaged in anal or oral sex with a man in the past 12 months; resided in Harare or Bulawayo for at least 1 month; spoke English, Shona, or Ndebele; provided written informed consent; and were in possession of a valid recruitment coupon if applicable. Enrolled participants completed a questionnaire and underwent HIV testing, and off-site viral load testing was done on all HIV-positive samples. Unweighted bivariate analyses and multivariable logistic regression models were used to evaluate the association of sociodemographic, behavioural, and other factors with HIV-positive status awareness among MSM, transgender women, and genderqueer individuals, and with viral load suppression among MSM. Analyses were done firstly using self-reported information and then by classifying those with a viral load of less than 200 copies per mL as being aware of their status and on treatment (viral load recategorisation).

FINDINGS

Among MSM, 248 (21%; 95% CI 19-24) of 1176 tested positive for HIV. Of those who tested positive, based on self-report, 119 (48%; 95% CI 42-54) reported knowing their HIV status, of whom 112 (94%; 88-98) reported using antiretroviral therapy (ART), of whom 89 (79%; 71-87) had viral load suppression. Based on viral load recategorisation, 180 (73%; 67-78) of 248 MSM testing HIV positive reported knowing their HIV status, of whom 174 (97%; 93-99) reported using ART, of whom 151 (87%; 81-91) had viral load suppression. 92 (28%; 23-33) of 335 transgender women and genderqueer individuals tested positive for HIV. Based on self-reports from these individuals 34 (37%; 27-48) of 92 participants reported knowing their HIV status, of whom 31 (91%; 76-98) reported using ART, of whom 27 (87%; 70-96%) had viral load suppression. Based on viral load recategorisation of data from transgender women and genderqueer participants, 53 (58%; 47-58) of 92 reported awareness of their HIV status, of whom 50 (94%; 84-99) reported using ART, of whom 46 (92%; 81-98) had viral load suppression. HIV-positive MSM aged 18-24 years had lower odds of being aware of their status than those aged at least 35 years (adjusted odds ratio [aOR] 0·34; 95% CI 0·13-0·92), as did HIV-positive MSM aged 25-34 years (aOR 0·26; 0·12-0·56). HIV-positive MSM aged 18-24 years also had a lower odds of having viral load suppression than those aged 35 years and older (aOR 0·35; 0·16-0·78), as did those aged 25-34 years (aOR 0·36; 0·19-0·67). No factors were significantly associated with awareness among transgender women and genderqueer individuals in multivariable models.

INTERPRETATION

Our survey showed that HIV prevalence was high and the largest difference between our results and the 90-90-90 treatment targets was in HIV status awareness, indicating the need for improvements in engaging MSM (especially young MSM), transgender women, and genderqueer individuals in HIV testing services.

Operationalizing the distribution of oral HIV self-testing kits to men who have sex with men (MSM) in a highly homophobic environment: the Nigerian experience

Background

Self-care health interventions are innovative approaches for improving health and achieving the sustainable development goals (SDGs). Men who have sex with men (MSM) have been disproportionately affected by Human Immunodeficiency Virus (HIV). In spite of this, stigma from healthcare workers has reportedly prevented MSM from accessing HIV testing in health facilities. This paper explored the operationalization of using key opinion leaders (KOLs) to distribute HIVST (HIV self-test) kits to MSM. This qualitative survey used a combination of in-depth interviews (IDI) with HIVST users and focus group discussions (FGDs) with KOLs to collect data three months after the distribution of the test kits by the KOLs. Thematic analysis of the data was carried out.

Result

Three themes were generated namely: KOLs serve as a trusted resource to promote and support HIVST for the MSM community; Skills and qualifications required for KOLs to effectively distribute and promote uptake of HIVST; and Effective strategies used to create demand and promote uptake of HIVST.

Conclusion

This study showed the practical steps involved in operationalizing KOL support system distribution of HIVST that positively influenced the testing experience for the participants irrespective of the HIV status and engagement in care. KOLs are a reliable resource to leverage for ensuring that HIV self-test kit is utilized and HIV positive individuals are linked to treatment and care in homophobic environments.

The Past, Present, and Future of PrEP implementation Among People Who Use Drugs

PURPOSE OF REVIEW

Recent HIV outbreaks among people who use drugs (PWUD) necessitate additional HIV prevention tools. Pre-exposure prophylaxis (PrEP) is highly efficacious yet uptake among PWUD remains exceedingly low. To address multilevel, complex barriers to PrEP use among PWUD, a range of intervention strategies are needed.

RECENT FINDINGS

The literature on interventions to optimize PrEP use among PWUD is nascent, comprising small pilots and demonstration projects in early phases of intervention development. Initial studies suggest that structural, healthcare, interpersonal, and individual-level interventions can improve PrEP use for PWUD, and a number of efficacy trials are underway. Future studies are needed to optimize the use of new PrEP modalities (e.g., injectable PrEP), simultaneously target multilevel challenges to PrEP use, and evaluate the integration of PrEP into other service settings and substance use treatment modalities.

Assessing the Potential Impact of Disruptions Due to COVID-19 on HIV Among Key and Lower-Risk Populations in the Largest Cities of Cameroon and Benin

BACKGROUND

The COVID-19 pandemic indirectly impacts HIV epidemiology in Central/West Africa. We estimated the potential impact of COVID-19-related disruptions to HIV prevention/treatment services and sexual partnerships on HIV incidence and HIV-related deaths among key populations including female sex workers (FSW), their clients, men who have sex with men, and overall.

SETTING

Yaoundé (Cameroon) and Cotonou (Benin).

METHODS

We used mathematical models of HIV calibrated to city population-specific and risk population-specific demographic/behavioral/epidemic data. We estimated the relative change in 1-year HIV incidence and HIV-related deaths for various disruption scenarios of HIV prevention/treatment services and decreased casual/commercial partnerships, compared with a scenario without COVID-19.

RESULTS

A 50% reduction in condom use in all partnerships over 6 months would increase 1-year HIV incidence by 39%, 42%, 31%, and 23% among men who have sex with men, FSW, clients, and overall in Yaoundé, respectively, and 69%, 49%, and 23% among FSW, clients, and overall, respectively, in Cotonou. Combining a 6-month interruption of ART initiation and 50% reduction in HIV prevention/treatment use would increase HIV incidence by 50% and HIV-related deaths by 20%. This increase in HIV infections would be halved by a simultaneous 50% reduction in casual and commercial partnerships.

CONCLUSIONS

Reductions in condom use after COVID-19 would increase infections among key populations disproportionately, particularly FSW in Cotonou, who need uninterrupted condom provision. Disruptions in HIV prevention/treatment services have the biggest impacts on HIV infections and deaths overall, only partially mitigated by equal reductions in casual/commercial sexual partnerships. Maintaining ART provision must be prioritized to minimize short-term excess HIV-related deaths.

HIV Testing, Knowledge and Willingness to Use PrEP Among Partnered Men Who Have Sex With Men in South Africa and Namibia

There is strong evidence that gay, bisexual and other men who have sex with men (GBMSM) in African countries experience high prevalence of HIV. However, missing from the literature is an understanding of the HIV risk behaviors and prevention needs of partnered GBMSM in African countries. The Together Tomorrow project sampled 440 partnered GBMSM (220 couples) in South Africa and Namibia. Prevalence of HIV was high at 42%, with 33% of men in sero-discordant relationships. Despite high levels of HIV testing in the past 6 months (65%), condom use with main and outside sex partners was low. Men reported low levels of willingness to use pre-exposure prophylaxis (PrEP) (16%). HIV testing in the past 12 months and willingness to use PrEP were significantly associated with recent binge drinking and substance use. Men in sero-discordant relationships, those with sexual agreements and those who had experienced any form of IPV were all less likely to report that they had recently tested for HIV. There is a need to develop interventions that meet the unique needs of African partnered GBMSM and tackle stigma and discrimination as drivers of HIV risk in these settings.

Overview of the epidemiological conditions of HIV among key populations in Africa

INTRODUCTION

Despite extraordinary progress in HIV treatment coverage and expanding access to HIV prevention services and that multiple African countries are on track in their efforts to reach 90-90-90 goals, the epidemic continues to persist, with prevalence and incidence rates too high in some parts of the continent to achieve epidemic control. While data sources are improving, and research studies on key populations in specific contexts have improved, work on understanding the HIV burdens and barriers to services for these populations remains sparse, uneven and absent altogether in multiple settings. More data have become available in the last several years, and data published in 2010 or more recently are reviewed here for each key population. This scoping review assesses the current epidemiology of HIV among key populations in Africa and the social and political environments that contribute to the epidemic, both of which suggest that without significant policy reform, these epidemics will likely continue.

RESULTS AND DISCUSSION

Across Africa, the HIV epidemic is most severe among key populations including women and men who sell or trade sex, men who have sex with men, people who inject drugs, transgender women who have sex with men and prisoners and detainees. These groups account for the majority of new infections in West and Central Africa, and an estimated 25% of new infections in East and Southern Africa, despite representing relatively small proportions of those populations. The HIV literature in Africa emphasizes that despite significant health needs, key populations experience barriers to accessing services within the healthcare and legal justice systems. Current shortcomings of surveillance systems in enumerating key populations impact the way funding mechanisms and resources are allocated and distributed. Adapting more equitable and epidemiologically sound frameworks will be necessary for current and future HIV programming investments.

CONCLUSIONS

Through this review, the available literature on HIV epidemiology among key populations in Africa brings to light a number of surveillance, programmatic and research gaps. For many communities, interventions targeting the health and security conditions continue to be minimal. Compelling evidence suggests that sweeping policy and programmatic changes are needed to effectively tackle the persistent HIV epidemic in Africa.

Geographical Disparities in HIV Seroprevalence Among Men Who Have Sex with Men and People Who Inject Drugs in Nigeria: Exploratory Spatial Data Analysis

BACKGROUND

The assessment of geographical heterogeneity of HIV among men who have sex with men (MSM) and people who inject drugs (PWID) can usefully inform targeted HIV prevention and care strategies.

OBJECTIVE

We aimed to measure HIV seroprevalence and identify hotspots of HIV infection among MSM and PWID in Nigeria.

METHODS

We included all MSM and PWID accessing HIV testing services across 7 prioritized states (Lagos, Nasarawa, Akwa Ibom, Cross Rivers, Rivers, Benue, and the Federal Capital Territory) in 3 geographic regions (North Central, South South, and South West) between October 1, 2016, and September 30, 2017. We extracted data from national testing registers, georeferenced all HIV test results aggregated at the local government area level, and calculated HIV seroprevalence. We calculated and compared HIV seroprevalence from our study to the 2014 integrated biological and behavioural surveillance survey and used global spatial autocorrelation and hotspot analysis to highlight patterns of HIV infection and identify areas of significant clustering of HIV cases.

RESULTS

MSM and PWID had HIV seroprevalence rates of 12.14% (3209/26,423) and 11.88% (1126/9474), respectively. Global spatial autocorrelation Moran I statistics revealed a clustered distribution of HIV infection among MSM and PWID with a <5% and <1% likelihood that this clustered pattern could be due to chance, respectively. Significant clusters of HIV infection (Getis-Ord-Gi* statistics) confined to the North Central and South South regions were identified among MSM and PWID. Compared to the 2014 integrated biological and behavioural surveillance survey, our results suggest an increased HIV seroprevalence among PWID and a substantial decrease among MSM.

CONCLUSIONS

This study identified geographical areas to prioritize for control of HIV infection among MSM and PWID, thus demonstrating that geographical information system technology is a useful tool to inform public health planning for interventions targeting epidemic control of HIV infection.

Prevalence and associated factors of HIV self-testing among men who have sex with men in Ningbo, China: a cross-sectional study

Background

HIV testing and early linkage to care are critical for reducing the risk of HIV transmission. HIV self-testing (HIVST) is a useful tool for increasing HIV testing frequency.This study aimed to investigate HIVST rates among men who have sex with men (MSM), the characteristics of MSM who had HIVST, and factors associated with HIVST uptake among MSM in Ningbo, China.

Methods

A cross-sectional study was conducted from April to October 2019 in Ningbo,China. Participants were aged at least 18 years and having had sexual contact with men in the past year. Proportions were used for categorical variables. Adjusted Odds Ratio (AOR) and 95% Confidence Interval (CI) for characteristics associated with HIVST uptake was processed by multivariable logistic regression models.

Results

Among a sample of 699 MSM recruited, 38.2% had reported previous use of an HIV self-test kit. A greater proportion of HIVST users had a higher frequency of HIV testing (≥ 2 times: 70.0% versus 41.2%, p < 0.001) in the past 1 year. The odds of older age (30–39 years: AOR = 0.49, CI 0.32–0.76; more than 40 years: AOR = 0.07, CI 0.04–0.14, compared to 18–29 years), bisexual (AOR = 0.49, CI 0.29–0.84) were lower among HIVST users,and were higher among MSM who were higher education level (high school: AOR = 2.82, CI 1.70–4.69, compared to middle school or less), gay apps use (AOR = 1.86, CI 1.13–3.05), multiple male sex partners (AOR = 1.90, CI 1.29–2.80), frequency of male–male sexual contact ≥ 1 times per week (AOR = 1.86, CI 1.30–2.66), syphilis infection (AOR = 5.48, CI 2.53–11.88).

Conclusions

Further HIVST education should be strengthened for school-aged children and teenagers, and free HIVST kits may be provided to high-risk MSM through gay apps and CBO to achieve the increased HIV testing frequency.

Anogenital Human Papillomavirus and HIV Infection in Rwandan Men Who Have Sex With Men

Men who have sex with men (MSM) have a high prevalence of anal and penile human papillomavirus (HPV) infections with MSM living with HIV (MSMLH) bearing the highest rates. Data on anogenital high-risk HPV (hrHPV) among MSM in Rwanda and the associated risk factors are scant.

HIV incidence in a multinational cohort of men and transgender women who have sex with men in sub-Saharan Africa: Findings from HPTN 075

Few studies have assessed HIV incidence in men who have sex with men (MSM) and transgender women (TGW) in sub-Saharan Africa (SSA). We assessed HIV incidence and its correlates among MSM and TGW in SSA enrolled in the prospective, multi-country HIV Prevention Trials Network (HPTN) 075 study, conducted from 2015 to 2017. Participants were enrolled at four sites in SSA (Kisumu, Kenya; Blantyre, Malawi; Cape Town and Soweto, South Africa). Eligible participants reported male sex assignment at birth, were 18 to 44 years of age, and had engaged in anal intercourse with a man in the preceding three months. Participation involved five study visits over 12 months. Visits included behavioral assessments and testing for HIV and sexually transmitted infections. Twenty-one of 329 persons acquired HIV during the study [incidence rate: 6.96/100 person-years (PY) (95% CI: 4.3, 10.6)]. Among TGW, HIV incidence was estimated to be 8.4/100 PY (95% CI: 2.3, 21.5). Four participants were found to have acute HIV infection at their first HIV-positive visit. HIV incidence varied among the four study sites, ranging from 1.3/100 PY to 14.4/100 PY. In multivariate longitudinal analysis, factors significantly associated with HIV acquisition were engagement in unprotected receptive anal intercourse [adjusted hazard ratio (AHR) 5.8, 95% confidence interval (CI): 2.4, 14.4] and incident rectal gonorrhea and/or chlamydia (AHR: 2.7, 95% CI: 1.1, 6.8). The higher HIV incidence in Cape Town compared to Blantyre could be explained by the higher prevalence of several risk factors for HIV infection among participants in Cape Town. Annual HIV incidence observed in this study is substantially higher than reported HIV incidence in the general populations in the respective countries and among MSM in the United States. Intensification of HIV prevention efforts for MSM and TGW in SSA is urgently needed.

Sex-seeking mobile application use and risk behavior among men who have sex with men in Brazil

This is a cross-sectional study based on an open web survey with the primary objective to assess associations between the use of apps for seeking sex partners and vulnerabilities related to human immunodeficiency virus (HIV) acquisition among men who have sex with men (MSM) in Brazil. Participants were recruited to the study through ads posted in social media such as Twitter, Facebook, and WhatsApp. Consenting respondents completed a questionnaire on demographics, history of sexually transmitted infections (STIs), and risk behaviors and perceptions, including calculation of the Risk Behavior Score for HIV infection proposed by Rocha et al. Among the 859 participants, 714 (83.1%) reported they used apps for seeking sex partners. Use of apps for seeking sex partners was associated with high-risk behavior for HIV infection, self-reported syphilis, self-perception of HIV risk, and use of marijuana. The use of apps for seeking sex partners has rapidly become the norm for MSM in Brazil. The associations with STIs and risk behaviors should be seen as an opening to improve public health, presenting opportunities to promote knowledge, safer sex practices, and referral to HIV/STI screening and prevention interventions.

Acceptability of pre-exposure prophylaxis for HIV prevention: facilitators, barriers and impact on sexual risk behaviors among men who have sex with men in Benin

BACKGROUND

In Benin, men who have sex with men (MSM) do not always use condoms during anal sex. Pre-exposure prophylaxis (PrEP) using Truvada® (tenofovir disoproxil fumarate / emtricitabine) may be a complementary HIV prevention measure for MSM. This study aimed at identifying the potential facilitators and barriers to the use of PrEP.

METHODS

This was a cross-sectional study conducted in 2018 among male-born MSM aged 18 years or older who reported being HIV-negative or unaware of their HIV status. The participants were recruited by the RDS technique (respondent driven sampling) in six cities of Benin. Logistic regression analyses, adapted to RDS statistical requirements, were performed to identify the factors associated with PrEP acceptability.

RESULTS

Mean age of the 400 MSM recruited was 26.2 ± 5.0 years. PrEP was known by 50.7% of respondents. The intention to use PrEP was expressed by 90% of MSM. If PrEP effectiveness were 90% or more, 87.8% of the respondents thought they would decrease condom use. In multivariate analysis, the facilitators associated with PrEP acceptability were: not having to pay for PrEP (odds ratio (OR) = 2.39, 95% CI: 1.50-4.46) and its accessibility within MSM networks (OR = 9.82, 95% CI: 3.50-27.52). Only one barrier was significant: the concern that taking PrEP be perceived as marker of adopting HIV risky behaviors (OR = 0.11, 95% CI: 0.04-0.30).

CONCLUSION

In Benin, not all MSM know about PrEP. But once well informed, the majority seems willing to use it if made available. The free availability of the drug and its accessibility in the MSM networks are important facilitators. The possibility of decrease in condom use should not be a barrier to the prescription of PrEP if made available.

Assessment of PrEP eligibility and uptake among at-risk MSM participating in a HIV-1 vaccine feasibility cohort in coastal Kenya

Introduction: Pre-exposure prophylaxis (PrEP) is provided free of costs to at-risk populations in Kenya, including men who have sex with men (MSM), but anal intercourse is not an eligibility criterion. We set out to determine PrEP eligibility, uptake and predictors of PrEP uptake among MSM enrolled in an HIV-1 vaccine feasibility cohort in coastal Kenya. Methods: We compared the number of MSM identified as eligible for PrEP from June-December 2017 by Kenyan Ministry of Health (MoH) criteria, which do not include reported anal intercourse, to those identified as eligible by a published MSM cohort-derived HIV-1 risk score (CDHRS). We determined PrEP uptake and assessed factors associated with uptake at first offer among eligible MSM followed up monthly. Results: Out of 167 MSM assessed for PrEP eligibility, 118 (70.7%) were identified by both MoH and CDHRS eligibility criteria; 33 (19.8%) by CDHRS alone, 11 (6.6%) by MoH criteria alone, and 5 (3.0%) by neither criterion. Of the men identified by CDHRS alone, the majority (24 or 72.7%) reported receptive anal intercourse (RAI). Of the 162 MSM eligible for PrEP, 113 (69.7%) accepted PrEP at first offer. Acceptance of PrEP was higher for men reporting RAI (adjusted prevalence ratio [aPR], 1.4; 95% confidence interval [CI], 1.0-1.9), having paid for sex (aPR, 1.3; 95% CI, 1.1-1.6) and group sex (aPR, 1.4; 95% CI, 1.1-1.8), after adjustment for sociodemographic factors. Conclusions: Assessing PrEP eligibility using the CDHRS identified 20% more at-risk MSM for PrEP initiation than when Kenyan MoH criteria were used. Approximately 70% of eligible men accepted PrEP at first offer, suggesting that PrEP is acceptable among at-risk MSM. MSM reporting RAI, group sex, or paying for sex were more likely to accept PrEP. Incorporating RAI into MoH PrEP eligibility criteria would enhance the impact of PrEP programming in Kenya.
