The Synergistic Impact of Sexual Stigma and Psychosocial Well-Being on HIV Testing: A Mixed-Methods Study Among Nigerian Men who have Sex with Men

Antiretroviral therapy non-adherence and its association with psychosocial factors in Nigeria: comparative study of sexual minority and heterosexual men living with HIV

Sexual minority men (gay, bisexual and other men who have sex with men; SMM) in Nigeria are disproportionately affected by HIV compared to heterosexual men. There is a dearth of research on the correlates of antiretroviral therapy (ART) non-adherence and correlates in both groups. The current study examined the associations of ART non-adherence with sociodemographic and psychosocial characteristics among a sample of Nigerian heterosexual and SMM. Between March and September 2014, we surveyed 120 SMM and 108 heterosexual men receiving ART in Lagos and Abuja, Nigeria. We specified univariate and multivariable linear regression models to examine correlates of ART non-adherence. We found that 50.8% and 29.6% of sexual minority and heterosexual men respectively self-reported ART non-adherence which was significantly associated with psychosocial factors such as stigma, depressive symptoms, and suicidality. Mental health care and psychosocial support should be incorporated into routine HIV care for Nigerian SMM living with HIV.

Increased Stigma, and Physical and Sexual Violence Against Men Who Have Sex with Men and Transgender Women in Sub-Saharan Africa: A Qualitative Evidence Synthesis Analyzing Social and Structural Barriers to HIV Testing and Coping Behaviors

In sub-Saharan Africa, accessing HIV testing services is a significant challenge for men who have sex with men (MSM) and transgender women (TGW). In this qualitative evidence synthesis, our aim is to understand social and structural barriers and how they hinder MSM's and TGW's access to HIV testing services in sub-Saharan African countries. We searched four selective databases (PubMed, Web of Science and CINAHL complemented with Google Scholar) for qualitative studies, published in English between January 2005 and December 2023, generated 1507 articles, of which 22 were included. Thematic synthesis was conducted for data synthesis. This led to five barriers that hinder HIV test uptake among MSM and TGW, which included: non-availability of tailored HIV testing services, stigma, lack of trust among service providers, sexual and physical violence, and criminalization of same sex relationship. To navigate these social and structural barriers and cope with fears of discrimination and criminalization, MSM and TGW engaged into riskier behaviors, including avoiding HIV testing, non-disclosure, or relying on informal or alternative sources of HIV testing. Decriminalization of same-sex relationship and peer-led HIV testing services were noted to address structural barriers, including stigma and poor access, and subsequently increase the participation in HIV testing services.

Associations Between Sexual Behavior Stigma and HIV Risk Behaviors, Testing, Treatment, and Infection Among Men Who have Sex with Men in Ukraine

Stigma toward same-sex behaviors may be a structural driver of HIV epidemics among men who have sex with men (MSM) in Eastern Europe and has been linked to adverse HIV-outcomes elsewhere. We explored associations between sexual behavior stigma with HIV risk behaviors, testing, treatment, and infection. From November 2017 to February 2018, MSM across 27 Ukrainian cities were recruited to cross-sectional surveys using respondent driven sampling. Eligible participants were cisgender males aged ≥ 14 years residing in participating cities that reported ≥ 1 sexual contact with another man in the prior 6 months. Participants self-reported experience of stigma (ever) and various HIV-outcomes and were tested for HIV antibodies. Regression models were used to explore associations between three sexual behavior stigma variables with demographic and HIV-related variables. Of 5812 recruited cisgender MSM, 5544 (95.4%) were included. 1663 (30.0%) MSM reported having experienced stigma due to being MSM from family and friends, 698 (12.6%) reported anticipated healthcare stigma, and 1805 (32.6%) reported general public/social stigma due to being MSM (enacted). All forms of stigma were associated with heightened HIV risk behaviors; those experiencing stigma (vs not) had more anal sex partners in the prior month and were less likely to have used condoms during their last anal intercourse. Stigma was not associated with HIV infection, testing, or treatment variables. A sizeable proportion of Ukrainian MSM reported ever experiencing stigma due to being MSM. MSM that had experienced stigma had higher odds of HIV sexual risk behaviors. Further study using longitudinal designs is required to determine causality.

Scoping review of HIV-related intersectional stigma among sexual and gender minorities in sub-Saharan Africa

OBJECTIVES

Sexual and gender minority (SGM) populations in sub-Saharan Africa (SSA) are disproportionately impacted by HIV and often face multiple HIV-related stigmas. Addressing these stigmas could reduce SGM HIV vulnerability but little is known about how the stigmas operate and intersect. Intersectional stigma offers a lens for understanding the experiences of stigmatised populations and refers to the synergistic negative health effects of various systems of oppression on individuals with multiple stigmatised identities, behaviours or conditions. This review aims to (1) assess how often and in what ways an intersectional lens is applied in HIV-related stigma research on SGM populations in SSA and (2) understand how intersectional stigma impacts HIV risk in these populations.

DESIGN

Scoping review following the Preferred Reporting Items for Systematic Reviews and Meta-Analysis extension for Scoping Reviews.

DATA SOURCES

Public health and regional databases were searched in 2020 and 2022.

ELIGIBILITY CRITERIA

Articles in French and English on HIV-related stigma and HIV outcomes among men who have sex with men, women who have sex with women and/or transgender individuals in SSA.

DATA EXTRACTION AND SYNTHESIS

Articles were screened and extracted twice and categorised by use of an intersectional approach. Study designs and stigma types were described quantitatively and findings on intersectional stigma were thematically analysed.

RESULTS

Of 173 articles on HIV-related stigma among SGM in SSA included in this review, 21 articles (12%) applied an intersectional lens. The most common intersectional stigmas investigated were HIV and same-sex attraction/behaviour stigma and HIV, same-sex attraction/behaviour and gender non-conformity stigma. Intersectional stigma drivers, facilitators and manifestations were identified across individual, interpersonal, institutional and societal socioecological levels. Intersectional stigma impacts HIV vulnerability by reducing HIV prevention and treatment service uptake, worsening mental health and increasing exposure to HIV risk factors.

CONCLUSION

Intersectional approaches are gaining traction in stigma research among SGM in SSA. Future research should prioritise quantitative and mixed methods investigations, diverse populations and intervention evaluation.

The Impacts of Stigma Against Sexual Minority Men Within and Between Various Socioecological Levels: Breaking the Vicious Cycle in Zambia

Sexual minority men (SMM) face persistent stigma in Zambia. From a holistic perspective, we aim to explore its impacts within and between multiple socioecological levels, demonstrating how their interactions create a vicious cycle of barriers to the well-being of SMM. In-depth interviews were conducted with 20 purposively recruited SMM from Lusaka, Zambia. All interviews were audio-recorded, after written consent, transcribed verbatim, and iteratively coded employing inductive (i.e., data-driven) approaches for thematic analysis using NVivo. Results suggest three key themes: (1) interpersonal socially perpetuated sexual minority stigma (SMS); (2) multidirectional interactions between psychosocial well-being and risk-taking behaviors; and (3) institutionally perpetuated SMS as a barrier to seeking and receiving health care. SMS permeates across all levels of the socioecological model to negatively impact the psychosocial well-being of SMM while acting also as a barrier to accessing HIV prevention and care. Our study necessitates structural public health intervention to decrease stigma and discrimination against SMM in Zambia, in efforts to increase their psychosocial well-being as well as their access to and utilization of HIV care by breaking the vicious cycle of SMS that pervades through the intrapersonal, interpersonal, and institutional levels of the socioecological model.

"It's Better If I Die Because Even in the Hospital, There is a Stigma, People Still Gossip": Gossip as a Culturally Shaped Labeling Process and Its Implications for HIV-Related Stigma in Botswana

This study qualitatively explores HIV-related gossip as both a manifestation and driver of HIV-related stigma, which is a known barrier to HIV testing and treatment in Botswana. Data were elicited from 5 focus group discussions and 46 semi-structured in-depth interviews with individuals living with HIV and community members with undisclosed serostatus in Gaborone, Botswana in 2017 (n = 84). Directed content analysis using the 'What Matters Most' theoretical framework identified culturally salient manifestations of HIV-related stigma; simultaneous use of Modified Labeling Theory allowed interpretation and stepwise organization of how the social phenomenon of gossip leads to adverse HIV outcomes. Results indicated that HIV-related gossip can diminish community standing through culturally influenced mechanisms, in turn precipitating poor psychosocial well-being and worsened HIV-related outcomes. These harms may be offset by protective factors, such as appearing healthy, accepting one's HIV status, and community education about the harms of gossip.

Depression and Sexual Stigma Are Associated With Cardiometabolic Risk Among Sexual and Gender Minorities Living With HIV in Nigeria

BACKGROUND

People living with HIV are vulnerable to cardiometabolic diseases. We assessed the prevalence of cardiometabolic risk factors (CMRF) and associations with sexual stigma and depression among sexual and gender minorities (SGM) in Abuja and Lagos, Nigeria.

METHODS

The TRUST/RV368 study enrolled SGM between March 2013 and February 2020. Participants were assessed for depression, sexual stigma, and CMRF. Robust multinomial logistic regression was used to estimate adjusted odds ratio (aORs) and 95% confidence intervals (CIs) for associations of depression, sexual stigma, and other factors with increasing numbers of CMRF.

RESULTS

Among 761 SGM, the mean age was 25.0 ± 6.0 years; 580 (76%) identified as cisgender men, 641 (84%) had ≥1 CMRF, 355 (47%) had mild-severe depression, and 405 (53%) reported moderate-high sexual stigma. Compared with individuals without depression, those with mild (aOR 8.28; 95% CI: 4.18 to 16.40) or moderate-severe depression (aOR 41.69; 95% CI: 9.60 to 181.04) were more likely to have 3-5 CMRF. Individuals with medium (aOR 3.17; 95% CI: 1.79 to 5.61) and high sexual stigma (aOR 14.42; 95% CI: 2.88 to 72.29) compared with those with low sexual stigma were more likely to have 3-5 CMRF. Participants age 25-34 years were less likely to have 3-5 CMRF (aOR 0.41; 95% CI: 0.23 to 0.73) compared with participants age younger than 25 years.

CONCLUSION

CMRF increased with severity of depression and sexual stigma, potentially predisposing SGM living with HIV to cardiometabolic diseases. Integrating interventions that address depression and sexual stigma in HIV care programs for SGM may improve cardiometabolic outcomes.

Les hommes bisexuels sont moins exposés au virus de l’immunodéficience humaine que les homosexuels exclusifs en Afrique subsaharienne

INTRODUCTION

In sub-Saharan Africa, as in the rest of the world, men who have sex with men (MSM) are at greater risk of HIV infection than the general population. Bisexuals are often perceived to be more at risk than exclusive gay men.

PURPOSE OF RESEARCH

We propose a review of epidemiological surveys conducted in sub-Saharan Africa since 2005 to provide an overview of knowledge on HIV exposure among gay/bisexual men.

RESULTS

We reviewed 355 publications and identified 62 measures of the association between bisexuality and HIV prevalence and 8 measures of the association between bisexuality and incidence. Except for 4 of 62 measures, the HIV prevalence observed among bisexuals was equal to or lower than that observed among exclusive gay men. In terms of incidence, all but one of the identified studies observed lower or equal HIV incidence among bisexuals. From a behavioural perspective, most studies found no difference in condom use. Bisexuals may have less frequent sex and consistently less receptive anal sex. They mainly started their sexual lives with men later, had fewer partners, and were less likely to know their HIV status.

CONCLUSIONS

Bisexuals are less likely to be at risk of HIV than exclusive gay men, partly because of behavioural differences. Prevention and treatment programs for MSM must take the specificities of bisexuals into account and design differentiated services.

Associations between mental health and HIV status among sexual minority and heterosexual adolescents in Nigeria

BACKGROUND

We aimed to determine associations between the mental health status of adolescents by self-reported sexual identity; and to determine associations between the mental health status of sexual minority adolescents living with and without HIV.

METHODS

This cross-sectional study collected data from Nigerians aged 13-19 years old using an online survey. We collected information on dependent (sexual identity) and independent (presence of depressive symptoms, generalised anxiety disorder, suicidal attempt/ideation, HIV status) study variables. A multivariate regression model determined associations between the dependent and independent variables. A second multivariate regression model was developed to establish associations between HIV status among sexual minority individuals and the dependent variables. All models were adjusted for age, sex assigned at birth and education level.

RESULTS

Among 1247 respondents living in Nigeria, 497 (39.9%) identified as sexual minority individuals. Compared with their heterosexual peers, sexual minority adolescents had significantly higher odds of reporting depressive symptoms (adjusted OR (AOR): 5.54; 95% CI: 4.10 to 7.47; p<0.001), high general anxiety (AOR: 3.56; 95% CI: 2.64 to 4.79; p<0.001) and history of suicidal attempt/ideation (AOR: 2.95; 95% CI: 2.20 to 3.94; p<0.001). Sexual minority adolescents living with HIV had significantly higher odds of high general anxiety (AOR: 2.42; 95% CI: 1.21 to 4.84; p=0.013), while those with unknown HIV status had significantly higher odds of depressive symptoms (AOR: 3.82, 95% CI: 2.78 to 5.27; p<0.001), high general anxiety (AOR: 3.09; 95% CI: 2.29 to 4.17; p<0.001) and suicidal attempt/ideation (AOR: 1.65; 95% CI: 1.22 to 2.24; p=0.001).

CONCLUSION

Sexual minority adolescents reported poorer mental health status than heterosexual adolescents. Although there was no significant difference in the mental health status of sexual minority adolescents living and not living with HIV, sexual minority adolescents with unknown HIV status reported worse mental health than their HIV-negative peers. Sexual minority adolescents in Nigeria need comprehensive rights-based care that improves access to mental health services, and those with unknown HIV status may need both HIV and mental health screening and care.

Motivations and Barriers to Routine HIV Testing Among Men Who Have Sex with Men in New York City

In-depth qualitative interviews explored the experiences and understandings of men 18-39 years old who have sex with men that could facilitate or prevent HIV testing and routine HIV testing. For many men who tested frequently, testing and routine testing were motivated by awareness of the benefit of prompt treatment; public health and provider encouragement to test periodically; responsibility towards sexual partners; and wanting to share a recent HIV-negative test result when seeking sex online. For some men, any testing was impeded by anxiety around possible HIV diagnosis that made testing a stressful occasion that required time and energy to prepare for. This anxiety was often compounded by stigma related to sex between men, having condomless sex, or having HIV. Routine testing could be further stigmatized as some men felt judged by testing providers or partners if they asked for a test or said they tested frequently. We describe efforts to promote testing and routine testing by countering fear and stigma associated with HIV and testing.

Associations between HIV testing and multilevel stigmas among gay men and other men who have sex with men in nine urban centers across the United States

Background

Complex manifestation of stigma across personal, community, and structural levels and their effect on HIV outcomes are less understood than effects in isolation. Yet, multilevel approaches that jointly assesses HIV criminalization and personal sexual behavior stigma in relation to HIV testing have not been widely employed or have only focused on specific subpopulations. The current study assesses the association of three types of MSM-related sexual behavior-related stigma (family, healthcare, general social stigma) measured at both individual and site levels and the presence/absence of laws criminalizing HIV transmission with HIV testing behaviors to inform HIV surveillance and prevention efforts among HIV-negative MSM in a holistic and integrated way.

Methods

We included nine National HIV Behavioral Surveillance (NHBS) 2017 sites: Baltimore, MD; Denver, CO; Detroit, MI; Houston, TX; Long Island/Nassau-Suffolk, NY; Los Angeles, CA; Portland, OR; San Diego, CA; and Virginia Beach and Norfolk, VA. Multivariable generalized hierarchical linear modeling was used to examine how sexual behavior stigmas (stigma from family, anticipated healthcare stigma, general social stigma) measured at the individual and site levels and state HIV criminalization legislation (no, HIV-specific, or sentence-enhancement laws) were associated with past-year HIV testing behaviors across sites (n = 3,278).

Results

The majority of MSM across sites were tested for HIV in the past two years (n = 2,909, 95.4%) with the average number of times tested ranging from 1.79 (SD = 3.11) in Portland, OR to 4.95 (SD = 4.35) in Los Angeles, CA. In unadjusted models, there was a significant positive relationship between stigma from family and being tested for HIV in the past two years. Site-level HIV-specific criminalization laws were associated with an approximate 5% reduction in the prevalence of receiving any HIV test in the past two years after individual level stigma and sociodemographic covariate adjustments (PR = 0.94, 95% CI, 0.90–0.99).

Conclusions

Structural barriers faced by MSM persist and ending the HIV epidemic in the US requires a supportive legal environment to ensure effective engagement in HIV services among MSM. Home-based solutions, such as self-testing, used to deliver HIV testing may be particularly important in punitive settings while legal change is advocated for on the community and state levels.

Religiosity and Conversion Therapy is Associated with Psychosocial Health Problems among Sexual Minority Men (SMM) in Nigeria

We investigated the associations between social marginalization, psychosocial health, and religiosity among sexual minority men (SMM) in Nigeria (N = 406). We conducted bivariate and multivariable logistic regression. Factors associated with reporting a history of conversion therapy at a religious institution were: being HIV positive, having depressive symptoms, reporting suicide thoughts, and reporting inability to access medical care. Factors associated with increased odds of agreeing that sex between two men was a sin were: residing in Plateau, being Muslim, and higher levels of internalized homophobia. Our findings support the need for LGBT-affirming religious doctrine, which has implications for the health of LGBT communities.

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.

Internalized Sexual Minority Stigma is Associated With HIV Testing Behavior Among Chinese Men Who Have Sex With Men: A Cross-Sectional Study

ABSTRACT

Although studies have examined the relationship between HIV-related stigma and HIV testing among men who have sex with men (MSM) in China, there is still a lack of knowledge regarding whether sexual minority stigma and HIV testing are associated. The purpose of this study was to identify the association between sexual minority- and HIV-related stigmas with HIV-testing behavior. A cross-sectional study was conducted in the Hunan Province of China. After controlling for covariates, the multivariate analyses showed that high internalized sexual minority stigma was negatively associated with HIV testing behavior in the previous year. However, anticipated sexual minority- and HIV-related stigmas were not associated with HIV-testing behavior. Findings suggest that internalized sexual minority stigma should be addressed in health care settings to encourage MSM to seek HIV testing services, especially considering the continuing HIV epidemic among MSM in China.

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.

Attaining 95-95-95 through Implementation Science: 15 Years of Insights and Best Practices from the Walter Reed Army Institute of Research's Implementation of the U.S. President's Emergency Plan for AIDS Relief

The Walter Reed Army Institute of Research (WRAIR) supports more than 350,000 people on lifesaving HIV treatment in Kenya, Nigeria, Tanzania, and Uganda through funding from the U.S. President’s Emergency Plan for AIDS Relief (PEPFAR). Here, we review and synthesize the range of impacts WRAIR’s implementation science portfolio has had on PEPFAR service delivery for military and civilian populations since 2003. We also explore how investments in implementation science create institutional synergies within the U.S. Department of Defense, contributing to broad global health engagements and improving health outcomes for populations served. Finally, we discuss WRAIR’s contributions to PEPFAR priorities through use of data to drive and improve programming in real time in the era of HIV epidemic control and public health messaging that includes prevention, the 95-95-95 goals, and comorbidities.

Field evaluation of HIV-1 viral load monitoring in adults and children receiving antiretroviral treatment in Nigeria by dried blood spot testing with RealTime HIV-1 on m2000

In resource-limited settings, use of dried blood spots (DBS) could be a pragmatic alternative to plasma for VL monitoring in people living with HIV (PLWH). We compared results from DBS to standard plasma VL testing under field conditions in patients receiving antiretroviral therapy (ART). DBS cards were prepared from venous blood (V-DBS), finger-pricks using micro-capillary tubes (M-DBS), and direct spotting (D-DBS). DBS and matched EDTA plasma were tested on the Abbott m2000 platform using the appropriate RealTime HIV-1 quantitative CE protocol. Matched plasma samples were also tested on the Roche COBAS Ampliprep/COBAS TaqMan version 2.0. Diagnostic accuracy indicators (sensitivity, specificity, misclassification rate, and kappa coefficient) for viral failure (VF) based on different VL threshold levels and agreement of absolute VL were calculated. A total of 669 participants provided 2676 samples. V-DBS had a peak sensitivity for VF of 89.1 % [95 % CI: 85.5-92.7] at the 1000 copies/mL threshold and a peak specificity of 97.4 % [95 % CI: 95.9-99.0] at the 5000 copies/mL threshold. The lowest proportion of upward misclassification (patients classified with VF who actually had viral suppression) for V-DBS was 3.1 % [95 % CI: 1.4-4.8] at the 5000 copies/mL threshold, whereas the lowest proportion of downward misclassification (patients classified as undetectable who actually had VF) was 10.9 % [95 % CI: 7.2-14.5] at the 1000 copies/mL threshold. Abbott RealTime HIV-1 VL results from all 3 DBS types for adults and children showed strong correlation with the gold standard plasma-based assay. DBS could be useful for monitoring VL in resource limited settings such as Nigeria.

Using factor analyses to estimate the number of female sex workers across Malawi from multiple regional sources

PURPOSE

Human immunodeficiency virus (HIV) risks are heterogeneous in nature even in generalized epidemics. However, data are often missing for those at highest risk of HIV, including female sex workers. Statistical models may be used to address data gaps where direct, empiric estimates do not exist.

METHODS

We proposed a new size estimation method that combines multiple data sources (the Malawi Biological and Behavioral Surveillance Survey, the Priorities for Local AIDS Control Efforts study, and the Malawi Demographic Household Survey). We used factor analysis to extract information from auxiliary variables and constructed a linear mixed effects model for predicting population size for all districts of Malawi.

RESULTS

On average, the predicted proportion of female sex workers among women of reproductive age across all districts was about 0.58%. The estimated proportions seemed reasonable in comparing with a recent study Priorities for Local AIDS Control Efforts II (PLACE II). Compared with using a single data source, we observed increased precision and better geographic coverage.

CONCLUSIONS

We illustrate how size estimates from different data sources may be combined for prediction. Applying this approach to other subpopulations in Malawi and to countries where size estimate data are lacking can ultimately inform national modeling processes and estimate the distribution of risks and priorities for HIV prevention and treatment programs.

Predictors of first-line antiretroviral therapy failure among adults and adolescents living with HIV/AIDS in a large prevention and treatment program in Nigeria

Background

A substantial number of persons living with HIV (PLWH) in Nigeria do not experience durable viral suppression on first-line antiretroviral therapy (ART). Understanding risk factors for first-line treatment failure informs patient monitoring practices and distribution of limited resources for second-line regimens. We determined predictors of immunologic and virologic failures in a large ART delivery program in Abuja, Nigeria.

Methods

A retrospective cohort study was conducted at the University of Abuja Teaching Hospital, a tertiary health care facility, using data from February 2005 to December 2014 in Abuja, Nigeria. All PLWH aged ≥ 15 years who initiated ART with at least 6-month follow-up and one CD4 measurement were included. Immunologic failure was defined as a CD4 decrease to or below pre-ART level or persistent CD4 < 100 cells per mm³ after 6 months on ART. Virologic failure (VF) was defined as two consecutive HIV-1 RNA levels > 1000 copies/mL after at least 6 months of ART and enhanced adherence counselling. HIV drug resistance (Sanger sequences) was analyzed using the Stanford HIV database algorithm and scored for resistance to common nucleoside reverse transcriptase inhibitors (NRTIs) and non-nucleoside reverse transcriptase inhibitors (NNRTIs). Univariate and multivariate log binomial regression models were used to estimate relative risks (RRs) and 95% confidence intervals (CIs).

Results

Of 12,452 patients followed, a total of 5928 initiated ART with at least 6 months of follow-up and one CD4 measurement. The entry point for 3924 (66.2%) was through the program’s own voluntary counseling and testing (VCT) center, while 1310 (22.1%) were referred from an outside clinic/program, 332 (5.6%) in-patients, and 373 (6.3%) through other entry points including prevention of mother to child transmission (PMTCT) and transferred from other programs. The mean CD4 at enrollment in care was 268 ± 23.7 cells per mm³, and the mean HIV-1 RNA was 3.3 ± 1.3.log₁₀ copies/mL. A total of 3468 (80.5%) received nevirapine (NVP) and 2260 (19.5%) received efavirenz (EFV)—based regimens. A total of 2140 (36.1%) received tenofovir (TDF); 2662 (44.9%) zidovudine (AZT); and 1126 (19.0%) stavudine (d4T). Among those receiving TDF, 45.0% also received emtricitabine (FTC). In a multivariate model, immunologic failure was more common among PLWH with female gender as compared to male [RR (95% CI) 1.22 (1.07–1.40)] and less common among those who entered care at the program’s VCT center as compared to other entry points [0.79 (0.64–0.91)], WHO stage 3/4 as compared to 1/2 [0.19 (0.16–0.22)], or CD4 200 + cells per mm³ as compared to lower [0.19 (0.16–0.22)]. Virologic failure was more common among PLWH who entered care at the program’s VCT center as compared to other entry points [RR (95% CI) 1.45 (1.11–1.91) and those with CD4 < 200 cells per mm³ at entry into care as compared to higher [1.71 (1.36–2.16)]. Of 198 patient-derived samples sequenced during virologic failure, 42 (21%) were wild-type; 145 (73%) carried NNRTI drug resistance mutations; 151 (76.3%) M184I/V; 29 (14.6%) had ≥ 3 TAMs, and 37 (18.7%) had K65R, of whom all were on TDF-containing first-line regimens.

Conclusions

In this cohort of Nigerian PLWH followed for a period of 9 years, immunologic criteria poorly predicted virologic failure. Furthermore, a subset of samples showed that patients failing ART for extended periods of time had HIV-1 strains harboring drug resistance mutations.

Experiences of minority stress among gay, bisexual, and other men who have sex with men (GBMSM) in Nigeria, Africa: The intersection of mental health, substance use, and HIV sexual risk behavior

Nigerian gay, bisexual, and other men who have sex with men (GBMSM) experience social marginalisation, discrimination and violence due to their sexual orientation and same-sex attraction, which may affect mental health, substance use, and HIV sexual risk behavior. The goal of the current study was to conduct formative qualitative research to gain better understanding of these issues among GBMSM in Lagos, Nigeria. Face-to-face, semi-structured, in-depth interviews were conducted with 30 GBMSM in Lagos, Nigeria. Data were analysed using a deductive content analysis approach. We found that Nigerian GBMSM experienced both general life stressors as well as proximal and distal sexual minority identity stressors, including rejection by family members, harassment, and physical violence perpetrated by the general public and police officers. Participants described dealing with mental health problems within the context of family rejection, experienced stigma due to sexual orientation, and feelings of social isolation. Substance use was described as occurring within the context of social settings. Lastly, some participants mentioned that they engaged in risky sexual behaviour while under the influence of alcohol and drugs. These findings call for comprehensive and innovative, GBMSM-affirming behavioural healthcare, substance cessation services, and innovative HIV prevention interventions specifically designed and tailored for Nigerian GBMSM.

Retention of a cohort of men who have sex with men and transgender women at risk for and living with HIV in Abuja and Lagos, Nigeria: a longitudinal analysis

INTRODUCTION

Men who have sex with men (MSM), and transgender women (TGW), face specific obstacles to retention in care, particularly in settings with stigmatization such as sub-Saharan Africa. We evaluated the impacts of HIV status and other factors on loss-to-follow-up (LTFU) and visit adherence among MSM and TGW in Abuja and Lagos, Nigeria.

METHODS

TRUST/RV368 is an open cohort that provides comprehensive and integrated prevention and treatment services for HIV and sexually transmitted infections (STIs) at community venues supportive of sexual and gender minorities. Recruitment began in March 2013 and participants were followed every three months for up to 18 months. LTFU was defined as not presenting for an expected visit in the past 180 days. Visit adherence was calculated as a rate of completed visits adjusted by the number of three-month intervals elapsed since enrolment. HIV and other factors predictive of LTFU and visit adherence were evaluated using Cox proportional hazards and Poisson regression models, respectively.

RESULTS

A total of 1447 participants who completed enrolment evaluations over two visits as of November 2018 were included in these analyses. Their median age was 24 years (interquartile range [IQR]: 21 to 28) and 53% (n = 766) were living with HIV. LTFU occurred in 56% (n = 808) and visit adherence was 0.62 (95% confidence interval: 0.61 to 0.64) visits per three-month interval. Participants at risk and living with HIV had median follow-up times of 12 months (IQR: 6 to 22), and 21 months (IQR: 12 to 30), respectively (p < 0.01). After controlling for other factors, LTFU was less common among participants living with HIV or other STIs and more common among those who did not own a cell phone, sold sex and had never undergone HIV testing prior to enrolment. These factors had parallel associations with visit adherence.

CONCLUSIONS

Retention was suboptimal in Nigerian clinics designed to serve MSM and TGW. Particularly high LTFU and low visit adherence among participants at risk for HIV could complicate deployment of HIV prevention interventions. Marketing the benefits of testing, improving access to cell phones and nurturing more trust with clients may improve retention among marginalized communities in Nigeria.

Characterizing Cross-Culturally Relevant Metrics of Stigma Among Men Who Have Sex With Men Across 8 Sub-Saharan African Countries and the United States

Overcoming stigma affecting gay, bisexual, and other men who have sex with men (MSM) is a foundational element of an effective response to the human immunodeficiency virus (HIV) pandemic. Quantifying the impact of stigma mitigation interventions necessitates improved measurement of stigma for MSM around the world. In this study, we explored the underlying factor structure and psychometric properties of 13 sexual behavior stigma items among 10,396 MSM across 8 sub-Saharan African countries and the United States using cross-sectional data collected between 2012 and 2016. Exploratory factor analyses were used to examine the number and composition of underlying stigma factors. A 3-factor model was found to be an adequate fit in all countries (root mean square error of approximation = 0.02-0.05; comparative fit index/Tucker-Lewis index = 0.97-1.00/0.94-1.00; standardized root mean square residual = 0.04-0.08), consisting of "stigma from family and friends," "anticipated health-care stigma," and "general social stigma," with internal consistency estimates across countries of α = 0.36-0.80, α = 0.72-0.93, and α = 0.51-0.79, respectively. The 3-factor model of sexual behavior stigma cut across social contexts among MSM in the 9 countries. These findings indicate commonalities in sexual behavior stigma affecting MSM across sub-Saharan Africa and the United States, which can facilitate efforts to track progress on global stigma mitigation interventions.

Validation of depressive symptoms, social support, and minority stress scales among gay, bisexual, and other men who have with men (GBMSM) in Nigeria, Africa: a mixed methods approach

BACKGROUND

Gay, bisexual, and other men who have sex with men (GBMSM) in Nigeria experience social marginalization, discrimination and violence due to their sexual identity, which may negatively impact physical, mental, and sexual health outcomes. Studies on GBMSM in Africa utilize measurement scales developed largely for populations in the Global North. The validity and reliability of these instruments-to our knowledge-have never been thoroughly investigated among GBMSM in Nigeria. The aim of the current study was to determine the validity and reliability of the English versions of the Center for Epidemiologic Studies Depression Scale (CESD-R), Multidimensional Scale of Perceived Social Support (MSPSS), and LGBT Minority Stress Measure among a large multi-state sample of GBMSM Nigeria.

METHODS

Between January and June 2019, we conducted cognitive interviews (N = 30) and quantitative assessments (N = 406) with GBMSM in Nigeria. The cognitive interviews assessed comprehension of scale items and elicited suggestions for scale modifications. The quantitative assessment was used to gather psychosocial health data and to evaluate psychometric properties and construct validity of the modified scales. We utilized confirmatory factor analysis to assess factor structure, correlation coefficients, and Cronbach's alpha to examine scale validity and internal consistency.

RESULTS

Based on participant feedback from the cognitive interviews, we made slight modifications (i.e., culturally appropriate word substitutions) to all three scales. Results of quantitative analyses indicated good psychometric properties including high factor loadings, internal consistency and construct validity among the CESD-R, MSPSS, and LGBT Minority Stress Measure among GBMSM in Nigeria.

CONCLUSION

These results suggests that modifying research scales to be more culturally relevant likely do not jeopardize their validity and reliability. We found that modified scales measuring depressive symptoms, perceived social support, and minority stress among GBMSM in Nigeria remained valid. More research is needed to explore whether the psychometric properties remain if the scales are translated into broken English (Pidgin) and other traditional Nigerian languages (Yoruba, Igbo and Hausa).

Implementation of and Early Outcomes From Anal Cancer Screening at a Community-Engaged Health Care Facility Providing Care to Nigerian Men Who Have Sex With Men

PURPOSE

Anal cancer risk is substantially higher among HIV-infected men who have sex with men (MSM) as compared with other reproductive-age adults, but screening is rare across sub-Saharan Africa. We report the use of high-resolution anoscopy (HRA) as a first-line screening tool and the resulting early outcomes among MSM in Abuja, Nigeria.

METHODS

From August 2016 to August 2017, 424 MSM enrolled in an anal cancer screening substudy of TRUST/RV368, a combined HIV prevention and treatment cohort. HRA-directed biopsies were diagnosed by histology, and ablative treatment was offered for high-grade squamous intraepithelial lesions (HSIL). HRA proficiency was assessed by evaluating the detection of squamous intraepithelial lesions (SIL) over time and the proportion biopsied. Prevalence estimates of low-grade squamous intraepithelial lesions and HSIL with 95% CIs were calculated. Multinomial logistic regression was used to identify those at the highest risk of SIL.

RESULTS

Median age was 25 years (interquartile range [IQR], 22-29), median time since sexual debut was 8 years (IQR, 4-12), and 59% (95% CI, 54.2% to 63.6%) were HIV infected. Rate of detection of any SIL stabilized after 200 screenings, and less than 20% had two or more biopsies. Preliminary prevalence estimates of low-grade squamous intraepithelial lesions and HSIL were 50.0% (95% CI, 44.7% to 55.3%) and 6.3% (95% CI, 4.0% to 9.3%). HIV infection, at least 8 years since anal coital debut, concurrency, and external warts were independently statistically associated with SIL.

CONCLUSION

Proficiency with HRA increased with experience over time. However, HSIL detection rates were low, potentially affected by obstructed views from internal warts and low biopsy rates, highlighting the need for ongoing evaluation and mentoring to validate this finding. HRA is a feasible first-line screening tool at an MSM-friendly health care facility. Years since anal coital debut and external warts could prioritize screening.

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

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

Individual and Sexual Network Predictors of HIV Incidence Among Men Who Have Sex With Men in Nigeria

BACKGROUND

To date, HIV incidence studies among men who have sex with men (MSM) across sub-Saharan Africa have focused on studying sexual risk practices with less focus on sexual networks.

SETTING

TRUST/RV368 conducted in Abuja and Lagos, Nigeria, recruited MSM using respondent-driven sampling and followed HIV-negative men for incident infection over 4 years.

METHODS

Four-hundred forty-one HIV-uninfected MSM underwent a parallel rapid HIV testing algorithm every 3 months for up to 18 months. HIV incidence per 100 person-years (PY) and 95% confidence intervals (CIs) were estimated using Poisson regression. Individual and network characteristics were examined using multivariable Cox-proportional hazards regression adjusted and unadjusted for respondent-driven sampling weights.

RESULTS

Among cohort members with a median age of 23 years [interquartile range (IQR): 20-27], 81 HIV infections occurred over 527 PY (incidence 15.4/100 PY; 95% CI: 12.3 to 19.0). The incidence rate was highest among 16-19 year olds as compared to those 25 years or older (30.9/100 PY; 95% CI: 22.1 to 45.3 vs. 6.9/100 PY; 95% CI: 4.2 to 10.9, respectively). Individual determinants included receptive partnerships, condomless sex, no history of testing for HIV, and rectal gonorrhea. Sexual networks were larger and consisted of an older sexual partner, although there was no clustering by recruitment networks.

CONCLUSIONS

These HIV incidence data reinforce the unmet HIV prevention needs among young MSM in Nigeria. Even in the context of emerging HIV diagnostic and prevention strategies, structural challenges including stigma and criminalization of same-sex practices highlight the need for novel implementation approaches in the context of MSM-friendly services.

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

BACKGROUND

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

METHODS

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

FINDINGS

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

INTERPRETATION

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

A syndemic of psychosocial health problems is associated with increased HIV sexual risk among Nigerian gay, bisexual, and other men who have sex with men (GBMSM)

Nigerian gay, bisexual and other men who have sex with men (GBMSM) experience negative psychosocial health problems, which may increase their risk for HIV infection. Few studies have explored the syndemic effect of co-occurring psychosocial health problems on HIV sexual risk among Nigerian GBMSM. We investigated the co-occurrence of syndemic psychosocial health problems and their synergistic effect on HIV risk behaviors. We assessed depressive symptoms, post-traumatic stress disorder, alcohol dependence, tobacco use, and hard-drug use. The outcome variables were the number of male sexual partners and consistent condom use. In a multivariable model, experiencing 4 or more psychosocial health problems - compared to experience none or one psychosocial health problem - was significantly associated with increasing number of male sexual partners. We found no statistically significant association between the number of syndemic psychosocial health problems and consistent condom use. Our study findings provides evidence of a synergistic relationship between negative psychosocial health factors and HIV sexual risk behavior. These findings underscore the importance of developing HIV prevention programming aimed at reducing HIV transmission risk that incorporate substance use and mental health treatments, in order to improve the overall health and quality of life for Nigerian GBMSM.

Sexual behavior stigma and depression among transgender women and cisgender men who have sex with men in Côte d'Ivoire

PURPOSE

Transgender women (TGW) and cisgender men who have sex with men (cisMSM) across sub-Saharan Africa experience health inequalities relative to other adults. Recent research has also revealed health inequalities between these often-conflated groups. Among TGW and cisMSM in Côte d'Ivoire, we sought to determine whether transgender female identity was associated with probable depression, and whether sexual behavior stigma mediated this association.

METHODS

In 2015-2016, a cross-sectional respondent-driven sampling survey of adult TGW and cisMSM was conducted across five cities. We conducted a three-way decomposition of mediation and interaction of gender identity and sexual behavior stigma. Depression was measured by the nine-item Patient Health Questionnaire (PHQ-9).

RESULTS

Of 1301 participants, 339 (26.1%) were TGW. The prevalence of probable depression was 22.7% among TGW and 12.2% among cisMSM (P < .001). After confounder adjustment, the relative risk of depression attributable to transgender female gender identity was 1.68 (95% CI = 1.36, 2.00) with 69.9% (95% CI = 42.6, 97.1) of this effect mediated by sexual behavior stigma. The effect of stigma on depression did not differ significantly by gender.

CONCLUSIONS

These data suggest that stigma mitigation interventions specifically addressing the stigma affecting transgender women may also address mental health inequalities between transgender women and cisMSM in Côte d'Ivoire.

Time to change the paradigm: limited condom and lubricant use among Nigerian men who have sex with men and transgender women despite availability and counseling

PURPOSE

This study characterized availability and uptake of condoms and condom-compatible lubricants (CCLs) at community-engaged condom education and distribution programs serving cisgender men who have sex with men and transgender women in Abuja and Lagos, Nigeria.

METHODS

Condoms and water-based CCLs were freely available to participants in the TRUST/RV368 cohort. Factors associated with their consistent use were assessed using Poisson regression with robust error variance to estimate relative risks (RRs) and 95% confidence intervals (CIs).

RESULTS

From March 2013-November 2017, 2090 cisgender men who have sex with men and transgender women enrolled with HIV prevalence 40.4% and incidence 12.8 cases per 100 person-years. Fifteen months after enrollment, the proportion who reported consistent condom and CCL use increased during receptive anal sex (21.7%-67.1%, P < .001) and insertive anal sex (25.4%-67.8%, P < .001). Multivariable analyses demonstrated independent impact of 15 months in care on uptake during both receptive (RR 2.62 [95% CI 2.29-3.00]) and insertive (RR 2.27 [95% CI 2.01-2.57]) sex.

CONCLUSIONS

Engagement in care improved condom and CCL uptake over time but inconsistent use remained common. Novel approaches to further increase uptake must be pursued alongside complementary strategies, such as sustained access to antiretroviral therapy for those living with HIV and provision of pre and postexposure prophylaxis for those at risk.
