The past, present, and future of HIV prevention: integrating behavioral, biomedical, and structural intervention strategies for the next generation of HIV prevention

A Review of Network Models for HIV Spread

BACKGROUND

HIV/AIDS has been a global health crisis for over 4 decades. Network models, which simulate human behavior and intervention impacts, have become an essential tool in guiding HIV prevention strategies and policies. However, no comprehensive survey of network models in HIV research has been conducted. This article fills that gap, offering a summary of past work and future directions to engage more researchers and inform policy related to eliminating HIV.

SETTING

Network models explicitly represent interactions between individuals, making them well-suited to study HIV transmission dynamics. Two primary modeling paradigms exist: a mechanistic approach from applied mathematics and a statistical approach from the social sciences. Each has distinct strengths and weaknesses, which should be understood for effective application to HIV research.

METHODS

We conducted a systematic review of network models used in HIV research, detailing the model types, populations, interventions, behaviors, datasets, and software used, while identifying potential future research directions.

RESULTS

Network models are particularly valuable for studying behaviors central to HIV transmission, such as partner selection and treatment adherence. Unlike traditional models, they focus on individual behaviors, aligning them with clinical practice. However, more accurate network data are needed for better model calibration and actionable insights.

CONCLUSIONS

This article serves as a point of reference for HIV researchers interested in applying network models and understanding their limitations. To our knowledge, this is the most comprehensive review of HIV network models to date.

Hepatitis B infection (HBsAg and HBeAg) status among women attending antenatal care at public healthcare facilities of South Africa, 2017

Eight years after WHO adopted a resolution to eliminate hepatitis B by the year 2030, the disease remains a global public health concern, with vertical transmission of HBV being a major obstacle to this goal. Our study aimed to determine the HBV infection status of pregnant women in South Africa at a national level to evaluate the risk of vertical transmission and provide evidence for public health decision-making. We conducted HBsAg testing on 1,942 HIV-uninfected and 2,312 HIV-infected pregnant women from South Africa's public health sector in 2017, followed by HBeAg testing on HBsAg-positive samples. Our data were stratified by five-year age groups and province. The overall HBV prevalence was 11.24% (478/4,254), significantly higher among HIV-infected women (15.83%) compared to HIV-uninfected women (5.77%, p = 0.007). HBV prevalence was highest among women 40-44 years (14.00%) and in Limpopo Province (19.35%). Coinfection rates of HIV-HBV ranged from 14.00% to 17.00% among women 15-44 years, and provincially, rates were highest in Limpopo, North West, and Western Cape Provinces (>20%). HBeAg prevalence among HBsAg positive women was 9.48%, with higher rates among HIV infected women (11.29%) compared to HIV-uninfected women (7.34%, p = 0.7931). HBeAg prevalence was highest among women 15-19 (10.81%), 20-24 (11.88%) and 40-44 years (25.00%), and provincially, highest in North West (26.67%). Our findings highlight the significant prevalence of HBV infection among pregnant women in 2017, emphasising concerns about vertical transmission, particularly given the high prevalence of HBeAg among HBsAg-positive women. We advocate for the prompt implementation of a universal birth dose of the HBV vaccine in South Africa to augment existing vaccination schedules and mitigate the risk of vertical transmission, thereby advancing progress towards WHO elimination targets.

Standard of prevention for infectious diseases' prevention clinical trials during pandemics: learning lessons for global policies from biomedical HIV prevention clinical trials and a case study of COVID-19

Lessons from biomedical HIV prevention research indicate that standard of prevention packages evolve over time, and require active engagement of stakeholders and community advocates to define packages accept to community members and trial participants. Using COVID-19 prevention research as an example, this paper discusses the reasons why a standard of prevention package must be defined for infectious diseases prevention research, what the minimum content of this package may be, the importance of stakeholder engagement in defining the package, the role of the government, and ethical considerations. As the experience from the HIV pandemic had shown, multiple ethics guidelines argue for a comprehensive standard of prevention package for biomedical HIV prevention trials that does not preclude the inclusion of newly developed HIV prevention tools including those experimental products listed for emergency use during health crisis. In the case of COVID-19, the standard of prevention package should include at a minimum, risk reduction counseling on physical distancing, provision of hand sanitizers, education on how to use available prevention tools, and provision for the possibility of vaccine-induced seropositivity. When pre-exposure prophylaxis studies are conducted for healthcare workers and home carers, personal protective equipment should be provided. Regional and country level regulatory provisions on these issues can provide critical guidance for research design and implementation.

Preventive measures against HIV among Uganda's youth: Strategies, implementation, and effectiveness

Preventing HIV among Uganda's youth is a critical public health priority due to the high prevalence of HIV/AIDS and the disproportionate burden of new infections among young people. This paper examines the preventive measures implemented to combat HIV/AIDS among Uganda's youth, focusing on strategies, implementation efforts, and the effectiveness of interventions. Comprehensive sexuality education programs have been implemented in schools and communities to provide young people with accurate information on HIV transmission, prevention methods, and reproductive health. Condom distribution and promotion campaigns target sexually active youth, while HIV testing and counseling services aim to reach youth in various settings, including health facilities and community outreaches. The implementation of HIV prevention strategies involves collaboration among government agencies, NGOs, healthcare providers, educators, and community leaders. Efforts are made to ensure that prevention programs are culturally appropriate, evidence-based, and responsive to the needs of young people. Despite progress in HIV prevention, challenges persist, including knowledge gaps, stigma, gender inequalities, and socio-economic factors. Continuous monitoring and evaluation are essential to assess the impact of interventions and identify areas for improvement. Recommendations include increasing funding for HIV prevention programs, strengthening policy frameworks, enhancing access to youth-friendly health services, integrating comprehensive sexuality education into school curricula, and fostering community engagement. By addressing these recommendations, Uganda can strengthen its HIV prevention efforts and reduce the incidence of HIV/AIDS among its youth population, ultimately contributing to improved health outcomes and well-being.

The potential of a hygiene-based message, preferred learning modalities, and *iLubricarte, Liberarte, Lavarte+!" or L 3 + for the prevention of HIV/STI in Peru

Background

Hygiene-based practices of lubrication, genital cleansing, postcoital urination, and rectal douching are common behaviors among populations at higher risk of human immunodeficiency virus (HIV)/sexually transmitted infections (STI). Yet, the role these behaviors have on HIV/STI risk has not been well elucidated, especially among transgender women (TW) and gay, bisexual, and other men who have sex with men (GBMSM). Additionally, advances in biomedical strategies have heralded a new era of HIV/AIDS prevention that may be accompanied by behavioral changes that lead to decreases in condom usage and subsequent changes to STI sequelae. Nevertheless, many people at higher risk are not benefiting equally from these options, strengthening the need for more sustainable, evidence-based methods.

Objectives

This study explored the knowledge, attitudes, and behaviors of hygiene-based practices, proven preventative methods, and preferred learning methods among Peruvian TW and GBMSM.

Methods

30 interviews and 50 questionnaires were conducted with TW (N=35), GBMSM (N=35), healthcare providers (N=5), and key community informants (N=5).

Results

Most participants perceived hygiene-based practices to be common behaviors and a significant aspect of sexual wellbeing. Educational materials utilizing social media and hosting in-person events were also viewed favorably, with value to enhancing HIV/STI knowledge.

Conclusions

Several barriers to autonomy surfaced in the data, including systemic disparities to adequate HIV/STI services, top vs. bottom social dynamics, and PrEP accessibility issues. Continued work is needed to address the barriers to the acceptability, feasibility, and potential efficacy of hygiene-based practices, biomedical/barrier strategies, and L 3 +.

"Why Not Just go on PrEP?": A Study to Inform Implementation of an HIV Prevention Intervention Among Hispanic/Latino Men Who Have Sex With Men in the Northeastern United States

BACKGROUND

Preexposure prophylaxis (PrEP) is an effective biological option for HIV prevention yet persistent disparities in PrEP uptake and retention exist among Hispanic/Latino men who have sex with men (MSM). We evaluated barriers and facilitators to PrEP care among Hispanic/Latino MSM at risk for and living with HIV.

SETTING

A small urban setting in the Northeastern United States.

METHODS

This was a mixed-methods, exploratory, sequential, qualitative and quantitative pilot study among Latino MSM at-risk and/or living with HIV across (1) semistructured qualitative interviews (N = 15) and (2) cross-sectional survey (N = 98).

RESULTS

Participants reported a diverse range of sexual identities, HIV statuses, and PrEP statuses. Qualitative participants described feelings of isolation in both Hispanic/Latino and queer communities that made it challenging to learn about HIV prevention or PrEP from peers. Participants in the survey indicated that they would be more inclined to uptake PrEP if PrEP were offered in primary care settings (n = 61; 62.2%); there were specific LGBTQ+ affirming medical settings (n = 36; 36.7%); and/or they could meet other people who are currently on PrEP and sharing experiences online (n = 46; 46.9%) or in person (n = 38; 38.8%). Findings were organized to reflect determinants and implementation strategies that could be used to improve PrEP uptake among this population.

CONCLUSIONS

This mixed-methods study identified several challenges and opportunities for increasing the reach of PrEP to Hispanic/Latino MSM. These findings should be used to inform tailored implementation strategies to promote PrEP uptake among this at-risk yet currently underserved population.

Informing Acceptability and Feasibility of Digital Phenotyping for Personalized HIV Prevention among Marginalized Populations Presenting to the Emergency Department

For marginalized populations with ongoing HIV epidemics, alternative methods are needed for understanding the complexities of HIV risk and delivering prevention interventions. Due to lack of engagement in ambulatory care, such groups have high utilization of drop-in care. Therefore, emergency departments represent a location with those at highest risk for HIV and in highest need of novel prevention methods. Digital phenotyping via data collected from smartphones and other wearable sensors could provide the innovative vehicle for examining complex HIV risk and assist in delivering personalized prevention interventions. However, there is paucity in exploring if such methods are an option. This study aimed to fill this gap via a cross-sectional psychosocial assessment with a sample of N=85 emergency department patients with HIV risk. Findings demonstrate that although potentially feasible, acceptability of digital phenotyping is questionable. Technology-assisted HIV prevention needs to be designed with the target community and address key ethical considerations.

Using Machine Learning to Identify Predictors of Sexually Transmitted Infections Over Time Among Young People Living With or at Risk for HIV Who Participated in ATN Protocols 147, 148, and 149

BACKGROUND

Sexually transmitted infections (STIs) among youth aged 12 to 24 years have doubled in the last 13 years, accounting for 50% of STIs nationally. We need to identify predictors of STI among youth in urban HIV epicenters.

METHODS

Sexual and gender minority (gay, bisexual, transgender, gender-diverse) and other youth with multiple life stressors (homelessness, incarceration, substance use, mental health disorders) were recruited from 13 sites in Los Angeles and New Orleans (N = 1482). Self-reports and rapid diagnostic tests for STI, HIV, and drug use were conducted at 4-month intervals for up to 24 months. Machine learning was used to identify predictors of time until new STI (including a new HIV diagnosis).

RESULTS

At recruitment, 23.9% of youth had a current or past STI. Over 24 months, 19.3% tested positive for a new STI. Heterosexual males had the lowest STI rate (12%); African American youth were 23% more likely to acquire an STI compared with peers of other ethnicities. Time to STI was best predicted by attending group sex venues or parties, moderate but not high dating app use, and past STI and HIV seropositive status.

CONCLUSIONS

Sexually transmitted infections are concentrated among a subset of young people at highest risk. The best predictors of youth's risk are their sexual environments and networks. Machine learning will allow the next generation of research on predictive patterns of risk to be more robust.

PrEP perception and experiences of adolescent and young gay and bisexual men: an intersectional analysis

Studies indicate gaps in knowledge about the barriers to access and adhere to HIV pre-exposure prophylaxis (PrEP) in adolescents. In this article, we explore the perceptions and experiences of young gay, bisexual, and other men who have sex with men (YGBMSM) of the search, use and adherence to PrEP, considering their positions according to social markers of difference such as race/skin color, gender, sexuality, and social status. Intersectionality provides theoretical and methodological tools to interpret how the interlinking of these social markers of difference constitutes barriers and facilitators in the PrEP care continuum. The analyzed material is part of the PrEP1519 study and is comprised of 35 semi-structured interviews with YGBMSM from two Brazilian capitals (Salvador and São Paulo). The analyses suggest connections between social markers of difference, sexual cultures, and the social meanings of PrEP. Subjective, relational and symbolic aspects permeate the awareness of PrEP in the range of prevention tools. Willingness to use and adhere to PrEP is part of a learning process, production of meaning, and negotiation in the face of getting HIV and other sexually transmittable infections and the possibilities of pleasure. Thus, accessing and using PrEP makes several adolescents more informed about their vulnerabilities, leading to more informed decision-making. Interlinking the PrEP continuum of care among YGBMSM with the intersections of the social markers of difference may provide a conceptual framework to problematize the conditions and effects of implementing this prevention strategy, which could bring advantages to HIV prevention programs.

Sub-district costs and efficiency of a combination HIV/AIDS prevention-intervention in the Northwest Province of South Africa

Background

We reviewed a combination prevention program to strengthen HIV prevention programming, community support mechanisms, community-based HIV testing, referral systems, and HIV prevention integration at the primary care level. The intervention included situational analysis to inform programming, community engagement and mobilization, and community-based biomedical and behavioral prevention. In support of PEPFAR's country-ownership paradigm, we costed the combination HIV prevention program to determine data needed for local ownership. This research used costing and health system perspectives.

Results

Cost per person reached with individual or small group prevention interventions ranged from $63.93 to $4,344.88. (cost per health facility strengthened). Personnel costs drove the intervention. This was true regardless of year or activity (i.e. wellness days or events, primary health care strengthening, community engagement, and wellness clubs).

Conclusions

Labor-intensive rather than capital-intensive interventions for low-income settings, like this one, are important for treating and preventing HIV/AIDS and other health conditions sustainably. Over time, costs shifted from international cost centers to in-country headquarters offices, as required for sustainable PEPFAR initiatives. Such costing center evolution reflected changes in the intervention's composition, including (1) the redesign and re-deployment of service delivery sites according to local needs, uptake, and implementation success and (2) the flexible and adaptable restructuring of intervention components in response to community needs.

The impact of financial incentives on HIV incidence among adolescent girls and young women in Eswatini: Sitakhela Likusasa, a cluster randomised trial

INTRODUCTION

Incentives conditional on school attendance or on remaining free of sexually transmitted infections have produced mixed results in reducing HIV incidence.

METHODS

HIV-negative adolescent girls and young women aged 15-22%-50% of whom were out of school-were recruited from 293 clusters in Eswatini from urban (30%) and rural areas (70%).Financial incentives conditional on education attendance were randomly allocated at the cluster level. All participants were further individually randomised into eligibility for a raffle incentive conditional on random selection into the raffle, on negative tests for syphilis and Trichomonas vaginalis and on being a raffle winner, creating four subarms in a 2×2 factorial design: no-intervention, raffle incentive, education incentive and raffle & education incentive. Randomisation was unblinded to participants.Logistic regressions were used in intention-to-treat analysis of HIV incidence over 3 years to estimate the impact of incentives conditional on school attendance and raffle incentives conditional on remaining sexually transmitted infection free.

RESULTS

The study recruited 4389 HIV-negative participants, who were distributed into four subarms: no intervention (n=1068), raffle incentive (n=1162), education incentive (n=1088) and raffle and education incentive (n=1071).At endline, 272 participants from 3772 for whom endline data were collected, tested positive for HIV. HIV incidence among participants in education treatment arm was significantly lower than in the education control arm, 6.34% (119/1878) versus 8.08% (153/1894) (p=0.041); OR: 0.766 (0.598 to 0.981); adjusted OR (aOR): 0.754 (0.585 to 0.972). Compared with the no intervention subarm, HIV incidence in the raffle and education incentive subarm was significantly lower, 5.79% (54/878) versus 8.84% (80/905); OR: 0.634 (0.443 to 0.907); aOR: 0.622 (0.433 to 0.893), while it was not significantly lower in the raffle incentive subarm.

CONCLUSION

Financial incentives conditional on education participation significantly reduced HIV infection among adolescent girls and young women in Eswatini and appear to be a promising tool for prevention in high HIV prevalence settings.

Validation of Brief Condom Use Attitudes Scales for Spanish-Speaking People Who Use Crack Cocaine in El Salvador

People who use crack cocaine (PWUCC) are a population severely impacted by a concentrated epidemic of HIV. Behavioral interventions to prevent and treat HIV among PWUCC have been implemented around the world including in low- and middle-income countries which have been disproportionately affected by HIV. However, few studies have validated and assessed psychometric properties of measures on PWUCC, especially in transnational populations. Our sample was comprised of 1324 PWUCC, Spanish mono-lingual speakers, residing in the metropolitan area of San Salvador, El Salvador. Exploratory factor analysis and subsequent confirmatory factor analysis using statistical softwares SPSS and Amos were conducted on three abbreviated and translated condom use attitude measures (i.e., Condom Use Attitudes Scale-Spanish Short Form, Condom Use Social Norm-Spanish Short Form [CUSN-SSF], Condom Use Self-Efficacy-Spanish Short Form). Convergent validity was examined by computing bivariate correlations between the scales and condom use and sexually transmitted disease diagnosis. Results indicated that a two-factor, 8-item correlated model for the CUAS-SSF scale had an excellent fit and adequate reliability (α = .76). The confirmatory factor analysis for the 5-item CUSN-SSF scale indicated a satisfactory fit with 3 of 6 fit indices indicating adequate fit. Analysis of the two-factor 5-item CUSE-SSF scale indicated satisfactory fit and adequate reliability (α = .84). There were significant correlations between all measures and with self-reported condom use. Results indicate that these brief measures are reliable and valid and can be utilized to assess the effectiveness of HIV risk reduction interventions among Spanish-speaking PWUCC.

Past dynamics of HIV transmission among men who have sex with men in Montréal, Canada: a mathematical modeling study

BACKGROUND

Gay, bisexual, and other men who have sex with men (gbMSM) experience disproportionate risks of HIV acquisition and transmission. In 2017, Montréal became the first Canadian Fast-Track City, setting the 2030 goal of zero new HIV infections. To inform local elimination efforts, we estimate the evolving role of prevention and sexual behaviours on HIV transmission dynamics among gbMSM in Montréal between 1975 and 2019.

METHODS

Data from local bio-behavioural surveys were analyzed to develop, parameterize, and calibrate an agent-based model of sexual HIV transmission. Partnership dynamics, HIV's natural history, and treatment and prevention strategies were considered. The model simulations were analyzed to estimate the fraction of HIV acquisitions and transmissions attributable to specific groups, with a focus on age, sexual partnering level, and gaps in the HIV care-continuum.

RESULTS

The model-estimated HIV incidence peaked in 1985 (2.3 per 100 person years (PY); 90% CrI: 1.4-2.9 per 100 PY) and decreased to 0.1 per 100 PY (90% CrI: 0.04-0.3 per 100 PY) in 2019. Between 2000-2017, the majority of HIV acquisitions and transmissions occurred among men aged 25-44 years, and men aged 35-44 thereafter. The unmet prevention needs of men with > 10 annual anal sex partners contributed 90-93% of transmissions and 67-73% of acquisitions annually. The primary stage of HIV played an increasing role over time, contributing to 11-22% of annual transmissions over 2000-2019. In 2019, approximately 70% of transmission events occurred from men who had discontinued, or never initiated antiretroviral therapy.

CONCLUSIONS

The evolving HIV landscape has contributed to the declining HIV incidence among gbMSM in Montréal. The shifting dynamics identified in this study highlight the need for continued population-level surveillance to identify gaps in the HIV care continuum and core groups on which to prioritize elimination efforts.

“I die silently inside”. Qualitative findings from a Study of People living with HIV who Migrate to and Settle in Canada

•

This study presents compelling accounts of African, Caribbean, and black (ACB) 2 immigrants who feel excluded, isolated, and distanced by others because of their positive 3 HIV status. 4.

•

Among ACB immigration applicants living with HIV in Canada, a positive HIV status 5 had significant consequences on a person's ability to access health and social care, stable 6 housing, meaningful employment, as well as movement within society. 7.

•

It is important to understand the experiences of racialized immigration applicants and 8 HIV screening processes during immigration from an intersectionality lens. 9.

•

Health and social care providers of ACB immigrants living with HIV must consider the 10 interaction of race, legal status, institutional laws and structures, gender, culture, trauma, 11 and intergenerational contexts in providing adequate and appropriate health and social 12 care to this population.

We report on qualitative findings from a mixed methods study, examining enacted and internalized stigma during mandatory HIV screening among immigration applicants living with HIV in Canada. Qualitative findings show alignment with characteristics of internalized HIV stigma. We conducted 34 semi-structured interviews, and analyzed the data through thematic analysis, using Intersectionality and the Internalized HIV Stigma Scale as our theoretical and analytical frameworks. Participants described experiences of enacted and internalized HIV stigma in ways that were consistent with the four main domains of stereotypes, disclosure concerns, social relationships, and self-acceptance, but also extended the description of HIV stigma beyond these domains. Experiences of internalized HIV stigma and enacted stigma during the Canadian Immigration Medical Examination could potentially influence individuals’ long-term engagement in the HIV care cascade during the process of migration to, and settlement in, Canada. We present recommendations for the broader migrant health research agenda, health and social care providers, and public health policies.

Using an Intersectional Framework to Understand the Challenges of Adopting Pre-exposure Prophylaxis (PrEP) Among Young Adult Black Women

Introduction

There is limited functional knowledge and utilization of pre-exposure prophylaxis (PrEP) among young adult Black cisgender women (YBW).

Methods

We conducted four focus groups with YBW using an intersectional framework to explore multiple levels of factors that impede YBW awareness, interest, and utilization of PrEP in conjunction with their sexual and reproductive healthcare needs.

Results

Influences at the cultural-environmental level included a lack of information and resources to access to PrEP and medical mistrust in the healthcare system. At the social normative level, influences included attitudes towards the long-term effects on sexual and reproductive health and self-efficacy to follow the PrEP regimen. At the proximal intrapersonal level, influences included anticipated HIV stigma from family and peers along with the fear of rejection from their main partners.

Conclusions

Translation of these results indicated that interventions to increase PrEP utilization and adherence among YBW will require multi-level strategies to address barriers to integrating HIV prevention into sexual and reproductive healthcare.

Knowledge and attitudes about HIV pre-exposure prophylaxis: Evidence from in-depth interviews and focus group discussions with policy makers, healthcare providers, and end-users in Lesotho

Studies on knowledge and attitudes about HIV pre-exposure prophylaxis (PrEP) have mostly focused on key populations in North America and Europe. To inform Lesotho's national rollout of PrEP to the general population, this study aimed to characterize knowledge and attitudes about PrEP among policy makers, implementing partners, healthcare providers, and PrEP end-users in Lesotho. Respondents were purposively selected to participate based on personal experience in the development and implementation of Lesotho's PrEP program, or the personal use of PrEP. We conducted 106 in-depth interviews with policy makers (n = 5), implementing partners (n = 4), and end-users (current PrEP users = 55; former PrEP users = 36; and PrEP "decliners" = 6). In addition, we held 11 focus group discussions (FGDs) with a total of 105 healthcare providers. Interview and FGD transcripts were analyzed following the tenets of Grounded Theory. Respondents expressed positive attitudes toward PrEP, owing to experienced and perceived personal, familial, and societal benefits. PrEP was viewed as i) an opportunity for serodiscordant couples to remain together, ii) a means of conceiving children with minimized risk of HIV infection, iii) providing a sense of agency and control, and iv) an avenue for addressing the HIV epidemic in Lesotho. Respondents demonstrated understanding of PrEP's intended use, eligibility requirements, and modality of use. However, respondents also reported that several important misconceptions of PrEP were common among adults in Lesotho, including a belief that PrEP protects against sexually transmitted infections other than HIV, promotes promiscuity, prevents pregnancy, causes seroconversion, and provides lifelong protection from taking the pill just once. In addition to building on the perceived advantages of PrEP to shape a positive message, Lesotho's national rollout of PrEP will likely benefit from a communication strategy that specifically addresses the common misconceptions of PrEP identified in this study.

Peer- and community-led responses to HIV: A scoping review

INTRODUCTION

In June 2021, United Nations (UN) Member States committed to ambitious targets for scaling up community-led responses by 2025 toward meeting the goals of ending the AIDS epidemic by 2030. These targets build on UN Member States 2016 commitments to ensure that 30% of HIV testing and treatment programmes are community-led by 2030. At its current pace, the world is not likely to meet these nor other global HIV targets, as evidenced by current epidemiologic trends. The COVID-19 pandemic threatens to further slow momentum made to date. The purpose of this paper is to review available evidence on the comparative advantages of community-led HIV responses that can better inform policy making towards getting the world back on track.

METHODS

We conducted a scoping review to gather available evidence on peer- and community-led HIV responses. Using UNAIDS' definition of 'community-led' and following PRISMA guidelines, we searched peer-reviewed literature published from January 1982 through September 2020. We limited our search to articles reporting findings from randomized controlled trials as well as from quasi-experimental, prospective, pre/post-test evaluation, and cross-sectional study designs. The overall goals of this scoping review were to gather available evidence on community-led responses and their impact on HIV outcomes, and to identify key concepts that can be used to quickly inform policy, practice, and research.

FINDINGS

Our initial search yielded 279 records. After screening for relevance and conducting cross-validation, 48 articles were selected. Most studies took place in the global south (n = 27) and a third (n = 17) involved youth. Sixty-five percent of articles (n = 31) described the comparative advantage of peer- and community-led direct services, e.g., prevention and education (n = 23) testing, care, and treatment programs (n = 8). We identified more than 40 beneficial outcomes linked to a range of peer- and community-led HIV activities. They include improved HIV-related knowledge, attitudes, intentions, self-efficacy, risk behaviours, risk appraisals, health literacy, adherence, and viral suppression. Ten studies reported improvements in HIV service access, quality, linkage, utilization, and retention resulting from peer- or community-led programs or initiatives. Three studies reported structural level changes, including positive influences on clinic wait times, treatment stockouts, service coverage, and exclusionary practices.

CONCLUSIONS AND RECOMMENDATIONS

Findings from our scoping review underscore the comparative advantage of peer- and community-led HIV responses. Specifically, the evidence from the published literature leads us to recommend, where possible, that prevention programs, especially those intended for people living with and disproportionately affected by HIV, be peer- and community-led. In addition, treatment services should strive to integrate specific peer- and community-led components informed by differentiated care models. Future research is needed and should focus on generating additional quantitative evidence on cost effectiveness and on the synergistic effects of bundling two or more peer- and community-led interventions.

Mediating Effects of Stigma and Depressive Symptoms in a Social Media-Based Intervention to Improve Long-term Quality of Life Among People Living With HIV: Secondary Analysis of a Randomized Controlled Trial

BACKGROUND

Mobile health (mHealth) interventions have been shown to effectively improve the quality of life (QOL) among people living with HIV. However, little is known about the long-term effects of mHealth interventions.

OBJECTIVE

This study aims to explore the intervention mechanisms of a social media-based intervention, Run4Love, on the QOL of people with HIV over across a 9-month follow-up period.

METHODS

We recruited people living with HIV who were concurrently experiencing elevated depressive symptoms from an HIV outpatient clinic in South China. A total of 300 eligible participants were randomized either to the intervention group or the control group in a 1:1 ratio after they provided informed consent and completed a baseline survey. The intervention group received a 3-month WeChat-based intervention, comprising cognitive-behavioral stress management (CBSM) courses and physical activity promotion. The control group received a printed brochure on nutrition guidelines in addition to the usual care for HIV treatment. Neither participants nor the research staff were blinded to group assignment. All patients were followed at 3, 6, and 9 months. The primary outcome was depressive symptoms. Structural equation model (SEM) with longitudinal data was conducted to examine the sequential mediating effects of HIV-related stigma and depressive symptoms on the long-term intervention effects on participants' QOL.

RESULTS

About 91.3% (274/300), 88.3% (265/300), and 86.7% (260/300) of all participants completed follow-up surveys at 3, 6, and 9 months, respectively. Results showed that the intervention had significantly improved participants' QOL at 9 months, via complete mediating effects of reduced HIV-related stigma at 3 months and decreased depressive symptoms at 6 months. No adverse events were reported.

CONCLUSIONS

These findings underscore the critical roles of HIV-related stigma and depressive symptoms in an mHealth intervention with long-term effects on QOL improvements. We call for targeted mHealth interventions to improve QOL among people living with HIV, especially social media-based interventions that can address HIV-related stigma and alleviate depressive symptoms.

Complex solutions for a complex problem: A meta-analysis of the efficacy of multiple-behavior interventions on change in outcomes related to HIV

OBJECTIVE

The purpose of this meta-analysis was to examine the success of multiple-behavior interventions and to identify whether the efficacy of such programs depends on the number of recommendations prescribed and the type of outcomes measured.

METHOD

We conducted a synthesis of 136 research reports (N = 59,330) using a robust variance estimate model (Tanner-Smith et al., 2016) to study change between baseline and the first follow-up across multiple-behavior interventions, single-behavior interventions, and passive controls.

RESULTS

Multiple-behavior interventions were more efficacious than their single-behavior counterparts (multiple-behaviors: d = .44 [95% confidence interval, CI [.27, .60]); single-behavior: d = .21 [95% CI [.00, .43]), with efficacy varying based on the type of outcomes measured. Publication bias analysis revealed a small asymmetry but controlling for it did not eliminate these effects. There was a strong linear relation between the number of recommendations prescribed by an intervention and intervention efficacy (B = .07, SE = .01, p < .001), with strongest improvements observed for interventions making five or more recommendations. These patterns remained when controlling for other intervention and population characteristics.

CONCLUSIONS

Multiple-behavior interventions are successful in the HIV domain and increasing the number of recommendations made in the intervention generally maximizes improvements. These findings provide insights that may guide the design and implementation of integrated interventions. (PsycInfo Database Record (c) 2021 APA, all rights reserved).

Knowledge, attitude, and preferred strategies towards HIV/AIDS prevention among adolescents attending secondary schools in South Western Uganda

BACKGROUND

Globally, HIV/AIDS continues to rise among adolescents. Ugandan studies have examined knowledge and attitudes regarding HIV/AIDS among adult populations. This study specifically paid attention to this particular age group of adolescents 12-19 years.

AIM

To explore HIV knowledge and attitudes among adolescents attending secondary schools Mbarara Uganda.

METHODS

A qualitative descriptive study was conducted in three secondary schools in South Western Uganda. Forty eight (48) adolescents with age range between 12-19 years were purposively recruited in the study. Data were collected from six focus groups and analyzed thematically. Ethical approval received from MUST (#05/10-17) and UNSCT (#SS4535) review committees.

RESULTS

Four themes emerged: Knowledge about HIV, sources of information, attitudes towards persons with HIV and prevention strategies. Most adolescents had the basic knowledge of HIV from multiple sources like social media, health workers, peers, and parents. Their attitudes toward individuals with HIV included compassion, shock, and uneasiness. Participants suggested prevention programs to be implemented in the schools emphasizing HIV education, life skills, sex education and the formation of peer groups.

CONCLUSIONS

The findings showed that most participants had knowledge about HIV and how it can be prevented however few had knowledge gap thinking that HIV does not exist.

Applying a Nursing Perspective to Address the Challenges Experienced by Cisgender Women in the HIV Status Neutral Care Continuum: A Review of the Literature

ABSTRACT

The field of HIV research has grown over the past 40 years, but there remains an urgent need to address challenges that cisgender women living in the United States experience in the HIV neutral status care continuum, particularly among women such as Black women, who continue to be disproportionately burdened by HIV due to multiple levels of systemic oppression. We used a social ecological framework to provide a detailed review of the risk factors that drive the women's HIV epidemic. By presenting examples of effective approaches, best clinical practices, and identifying existing research gaps in three major categories (behavioral, biomedical, and structural), we provide an overview of the current state of research on HIV prevention among women. To illustrate a nursing viewpoint and take into account the diverse life experiences of women, we provide guidance to strengthen current HIV prevention programs. Future research should examine combined approaches for HIV prevention, and policies should be tailored to ensure that women receive effective services that are evidence-based and which they perceive as important to their lives.

Evidence and gaps in the literature on HIV/STI prevention interventions targeting migrants in receiving countries: a scoping review

BACKGROUND

Evidence suggests that migration increases vulnerability to human immunodeficiency virus (HIV) and other sexually transmitted infections (STI). However, there is limited knowledge about what has been done or needs to be done to address migrants' vulnerability in receiving countries.

OBJECTIVES

A scoping review was carried out to map the existing literature in this field, describe its characteristics, identify gaps in knowledge and determine whether a Sexual and Reproductive Health and Rights (SRHR)-perspective was applied.

METHODS

We used the Arksey and O'Malley framework and the Joanna Briggs Institute guidelines for scoping reviews and subsequent enhancements proposed by other authors. We searched three databases and grey literature to identify relevant publications.

RESULTS

A total of 1,147 records were found across the three electronic databases and compiled. Of these, only 29 papers that met the inclusion criteria were included. The review shows that research in this field is dominated by studies from the USA that mostly include behavioural interventions for HIV and HBV prevention among migrants from Latin America and Asian countries, respectively. None of the interventions integrated an SRHR perspective. The intervention effects varied across studies and measured outcomes. The observed effects on knowledge, attitudes, perceptions, behavioural intentions and skills were largely positive, but reported effects on testing and sexual risk behaviours were inconsistent.

CONCLUSIONS

There is a need for good quality research, particularly in parts of the world other than the USA that will address all STIs and specifically target the most vulnerable subgroups of migrants. Further research requires greater scope and depth, including the need to apply an SRHR perspective and incorporate biomedical and structural interventions to address the interacting causes of migrants' vulnerability to HIV/STIs.

CDC's Community-Based Organization Behavioral Outcomes Project: Perspectives for Researchers, Implementers and Funders

Behavioral interventions have been a crucial tool for the prevention of HIV transmission since early in the epidemic. The Centers for Disease Control and Prevention (CDC) has provided funding for evidence-based behavioral interventions (EBIs) at health departments and community-based organizations (CBOs) since 2004. From 2006 to 2015, CDC funded 25 CBOs to evaluate one or more of seven EBIs designed to prevent HIV through the Community-based Organization Behavioral Outcomes Project (CBOP) as implemented outside of a research setting. For each EBI, CBOP showed that most HIV risk behaviors improved after the intervention, and improvements were similar to those observed in research studies. Our findings show that behavioral interventions can be successfully implemented in real-world settings. Although the focus of HIV prevention has largely shifted toward biomedical interventions in recent years, successful implementation often depends on behavioral components. Lessons from CBOP can inform future efforts to develop and implement behavioral interventions for HIV and other areas of public health.

Improve the Quality of Life Related to HIV and the Black Community: HIV and AIDS Inequity in the Black Community: Proximal Solutions to Distal Determinants

This literature review describes the historical impact of HIV and AIDS among Black populations in United States (US), as well as the misalignment between root causes of HIV-related inequities and HIV prevention efforts. Specifically, we describe how distal factors (including structural racism) contribute to the disproportionate rates of HIV infection within Black communities. Further, we highlight consequences of focusing primarily on proximal determinants of acquiring HIV. Finally, we share some brief conclusions and recommendations to help move towards eliminating HIV and AIDS inequities among Black populations.

Combination HIV Prevention Strategies Among Montreal Gay, Bisexual, and Other Men Who Have Sex with Men in the PrEP Era: A Latent Class Analysis

Pre-exposure prophylaxis (PrEP) became publicly available in Quebec for gay, bisexual and other men who have sex with men (GBM) in 2013. We used baseline data from Engage, a cohort of GBM recruited by respondent-driven sampling, to examine patterns of combination HIV prevention use among Montreal GBM since PrEP became available. Latent class analysis, stratified by HIV status, was used to categorize GBM by self-reported use of biomedical and behavioural prevention strategies. Correlates of resulting classes were identified using multinomial logistic regression. Among HIV-negative/unknown GBM (n = 968), we identified four classes: low use of prevention (32%), condoms (40%), seroadaptive behaviour (21%), and biomedical (including PrEP; 7%). Those using prevention (condoms, seroadaptive behaviour, and biomedical) had a higher number of anal sex partners and were more likely to report a recent sexually transmitted infection diagnosis. GBM using biomedical prevention also had a higher level of formal education. Among GBM living with HIV (n = 200), we identified three classes: mainly antiretroviral treatment (ART) with viral suppression (53%), ART with viral suppression and condoms (19%), and ART with viral suppression and seroadaptive behaviour (18%). Again, the number of anal sex partners was higher among those using condoms and seroadaptive behaviours. Our findings show antiretroviral-based prevention, either alone or in combination with other strategies, is clearly a component of the HIV prevention landscape for GBM in Montreal. Nevertheless, PrEP uptake remains low, and there is a need to promote its availability more widely.

GPS: A Randomized Controlled Trial of Sexual Health Counseling for Gay and Bisexual Men Living With HIV

Gay, bisexual, and other men who have sex with men (GBM) continue to have high rates of HIV and sexually transmitted infections, including syphilis. GBM have therefore been identified by public health agencies as a high-priority population to reach with prevention initiatives. Despite the importance of mental health in preventing HIV and related infections, there is a shortage of credentialed mental health professionals to deliver behavioral Counseling interventions. The current study evaluated the efficacy of GPS, a community-based and peer-delivered sexual health promotion motivational interviewing-based intervention for HIV-positive GBM who engaged in condomless anal sex (CAS) in the past 2 months. GPS prevention counseling demonstrated a 43% relative reduction at 3-month follow-up in CAS with serodiscordant partners and significant reductions in sexual compulsivity. The study demonstrated that community-based counselors can administer an efficacious motivational interviewing program, and suggests a continued benefit of counseling methods to promote the sexual health of higher risk populations.

Replication of influential studies on biomedical, social, behavioural and structural interventions for HIV prevention and treatment

Replication is an important tool to promote high quality research and ensure policy makers can rely on studies in making guidelines or funding programs. By ensuring influential studies are replicable we provide assurance that the policies based on these studies are well-founded and the conclusions and recommendations are robust-to different estimation models or different choices. In this paper, we argue that replication is not only useful but necessary to ensure that an author's choice in how to analyse data is not the only factor that determines whether an intervention is effective or not. We also show that while most research is done well and provides robust results, small differences can lead to different interpretations and these differences need to be acknowledged. This special issue highlights 5 such replication studies, which are replications of influential studies on biomedical, social, behavioural and structural interventions for HIV prevention and treatment. We reflect on their findings. Four out of five studies, which conduct push button replication and pure replication, were able to reproduce the results of the original studies with minor differences, mainly due to minor typographical errors or rounding differences. The analysis of the measurement and estimation analyses conducted in these five studies reveals that the original results are not very robust to alternative analytical approaches, especially when these results rely on a small number of observations. In these cases, the original results are weakened. Furthermore, in contrast to the original papers, two of the five included replication studies conducted a theory of change analysis-to explore how or why the interventions work (or do not) not just whether the intervention works or not. These two analyses indicate that the estimated impacts of the interventions are drawn from few mediators. In addition, they demonstrate that, in some cases, a lack of effect may be related to lack of adequate exposure to the intervention rather than inefficacy of the intervention per se. However, overall, the included replication studies show that the results presented in the original papers are trustworthy and robust, especially when based on larger sample sizes. Replication studies can not only verify the results of a study, they can also provide additional insights on the published results, such as how and why an intervention was effective or less effective than expected. They can thus be a tool to inform the research community and/ or policymakers about whether and how interventions could be adopted, which need to be tested further, and which should be discontinued because of their ineffectiveness. Thus, publishing these replication studies in peer-reviewed journals makes the work public and publicized. The work advances knowledge, and publication should be encouraged, as it is for other types of research.

A Mobile Gaming Intervention for Persons on Pre-Exposure Prophylaxis: Protocol for Intervention Development and Randomized Controlled Trial

Background

In the United States, young minority men who have sex with men (MSM) are the most likely to become infected with HIV. Pre-exposure prophylaxis (PrEP) is an efficacious and promising prevention strategy. However, PrEP’s safety and effectiveness can be greatly compromised by suboptimal adherence to treatment. To maximize the positive impact of PrEP, it is necessary to combine its prescription with cost-effective behavioral interventions that promote adherence and decrease HIV risk behaviors. In this project, we developed a theoretically informed app/gaming intervention to engage young MSM in learning information, practicing behaviors, and improving motivation for HIV preventative behaviors and PrEP adherence.

Objective

The goal of this project was to develop and test a cutting-edge, engaging, and entertaining app/gaming intervention for improving adherence to PrEP and building HIV prevention knowledge, skills, and behavior.

Methods

This study was conducted in two phases. In the developmental phase, we conducted qualitative interviews with young MSM (n=20) to guide the development of the gaming intervention. In the randomized controlled trial, we tested the preliminary efficacy of the gaming intervention compared to a comparison condition among young MSM. Subjects were recruited from the University of Mississippi Medical Center HIV/STI testing clinics (n=60).

Results

Institutional review board approval was received in February 2015. Research activities began in June 2015 and are still ongoing.

Conclusions

This app/gaming intervention aimed to improve PrEP adherence and HIV preventative behaviors in young MSM. Engaging young MSM in learning information, practicing behaviors, and improving motivation for increased adherence to PrEP has the potential to decrease HIV seroconversion. It is important to develop interventions that are enjoyable, engaging, and easily incorporated into clinical settings.

Willingness of Adults in the United States to Receive HIV Testing in Dental Care Settings: Cross-Sectional Web-Based Study

Background

The Centers for Disease Control and Prevention estimates that 1.1 million people in the United States are living with HIV and 1 in 8 are estimated to be unaware of their serostatus. Little is known about whether individuals would consider being tested for HIV in nontraditional health care settings such as a dentist’s office. Studies in selected US cities have indicated high acceptability of receiving an HIV test among people attending dental clinics. However, we are not aware of studies that have assessed willingness to receive HIV testing in dental care settings at a national level.

Objective

Using a web-based sample of adult residents of the United States, we sought to assess the self-reported willingness to receive any type of HIV testing (ie, oral fluid rapid testing, finger-stick blood rapid testing, or venipuncture blood testing) in a dental care setting and evaluate independent associations of willingness with the extent to which dental care providers were perceived as knowledgeable about HIV and how comfortable participants felt discussing HIV with their dental care providers.

Methods

Participants were recruited using banner advertisements featured on social networking platforms (Facebook and Instagram) from December 2018 to February 2019. Demographic and behavioral data including information on sexual behaviors in the past 6 months, HIV testing history, and dental/health care–seeking history were collected using an anonymous web-based survey. Willingness to receive any type of HIV testing in a dental care setting was assessed on 4-point scale from very willing to very unwilling. Factors independently associated with participants’ willingness were identified using a multivariable logistic regression model.

Results

Of the 421 participants in our study aged 18 to 73 years, 271 (64.4%) reported having oral sex, 197 (46.8%) reported having vaginal sex, and 136 (32.3%) reported having anal sex in the past 6 months. Approximately one-third had never been tested for HIV (137/421, 32.5%), and the same proportion had not been tested in the past year (137/421, 32.5%). Most participants had dental insurance coverage (356/421, 84.6%), and more than three-fourths reported being very or somewhat willing (326/421, 77.4%) to receive any type of HIV testing in a dental care setting. Higher levels of willingness were associated with being 18 to 24 years versus ≥35 years (aOR 3.22, 95% CI 1.48-6.98), 25 to 34 years versus ≥35 years (aOR 5.26, 95% CI 2.52-10.98), believing that one’s dental care provider is knowledgeable about HIV (aOR 2.04, 95% CI 1.06-3.92), and feeling comfortable discussing HIV with one’s dental care provider (aOR 9.84, 95% CI 3.99-24.27).

Conclusions

Our data indicate high acceptability of receiving HIV testing in a dental care setting, especially among those who report having a positive patient-provider relationship. Future research should focus on assessing dental care providers’ attitudes, self-efficacy, and beliefs about whether HIV testing fits into the scope of dentistry.

Determinants of HIV testing among Filipino women: Results from the 2013 Philippine National Demographic and Health Survey

BACKGROUND

The prevalence of having ever tested for HIV in the Philippines is very low and is far from the 90% target of the Philippine Department of Health (DOH) and UNAIDS, thus the need to identify the factors associated with ever testing for HIV among Filipino women.

METHODS

We analysed the 2013 Philippine National Demographic and Health Survey (NDHS). The NDHS is a nationally representative survey which utilized a two-stage stratified design to sample Filipino women aged 15-49. We considered the following exposures in our study: socio-demographic characteristics of respondent and her partner (i.e., age of respondent, age of partner, wealth index, etc.), sexual practices and contraception (i.e., age at first intercourse, condom use, etc.), media access, tobacco use, HIV knowledge, tolerance to domestic violence, and women's empowerment. The outcome variable is HIV testing. We used logistic regression for survey data to study the said associations.

RESULTS

Out of 16,155 respondents, only 372 (2.4%) have ever tested for HIV. After adjusting for confounders, having tertiary education (adjusted odds ratio (aOR) = 2.15; 95% Confidence Interval (CI): 1.15-4.04), living with partner (aOR = 1.72; 95% CI: 1.19-2.48), tobacco use (aOR = 1.87; 95% CI: 1.13-3.11); belonging to the middle class (aOR = 2.72; 95% CI: 1.30-5.67), richer (aOR = 3.00; 95% CI: 1.37-5.68), and richest (aOR = 4.14; 95% CI: 1.80-5.91) populations, having weekly television access (aOR = 1.75; 95% CI: 1.04-2.94) or internet access (aOR = 2.01; 95% CI: 1.35-3.00), living in a rural area (aOR = 1.87; 95% CI: 1.34-2.61); and being a Muslim (aOR = 2.30; 95% CI: 1.15-4.57) were associated with ever testing for HIV.

CONCLUSIONS

The low percentage of respondents who test for HIV is a call to further strengthen efforts to promote HIV testing among Filipino women. Information on its determinants can be used to guide the crafting and implementation of interventions to promote HIV testing to meet DOH and UNAIDS targets.

Transgender Women's Concerns and Preferences on Potential Future Long-Acting Biomedical HIV Prevention Strategies: The Case of Injections and Implanted Medication Delivery Devices (IMDDs)

There are several long-acting biomedical HIV prevention products in the development pipeline, including injections and implanted medication delivery devices (IMDDs). It is critical to understand concerns and preferences on the use of these products in populations that shoulder a disproportionate burden of the HIV epidemic, such as transgender women. This will allow researchers and public health professionals to construct interventions tailored to the needs of these women to promote optimal use of these tools. In studies of other biomedical HIV prevention products (e.g., oral PrEP) it is clear that transgender women have unique concerns related to the use of these strategies. This may have an impact on this group's uptake and sustained use of longacting HIV prevention products. This study conducted four focus groups with N = 18 transgender women in New York City to understand their concerns and preferences on long-acting PrEP injections and IMDDs. Findings showed that participants were overwhelmingly positive about long-acting HIV prevention strategies, though they had some apprehensions. Overall, participants felt that injections and IMDDs could help address adherence challenges, and that transgender-specific needs should be addressed during clinical trials. Also, there were concerns related to injection or IMDD logistics, concerns about injections' or IMDDs' presence in the body, and familiarity with these products affected participants' opinions on them. Findings from this work can be used to inform protocols, measures, materials, and adherence interventions in future initiatives for transgender women using PrEP injections or IMDDs.

Barriers to post exposure prophylaxis use among men who have sex with men in sub-Saharan Africa: An online cross-sectional survey

Background

Curbing new HIV infections among MSM in SSA remains problematic, due to cultural beliefs, norms that oppose same-sex acts, and criminalization of same-sex acts. No study focused on barriers to PEP use in SSA region has been conducted. Our study focused on identifying barriers to Post-Exposure Prophylaxis (PEP) use among MSM in sub-Saharan Africa (SSA).

Methods

An online cross-sectional survey was sent out to members of 14 Lesbian, Gay, Transgender, Bisexual, Queer (LGBTQ) associations in SSA, to identify barriers to PEP utilization in MSM. A total of 207 MSM from 22 countries in SSA completed the survey between 8 January 2019 and 23 February 2019. Descriptive statistics were generated, chi-square and backward stepwise logistic regression analysis were performed to evaluate the association between the outcome “PEP use” and other variables.

Results

Most of the MSM were aged 18 to 30, and the majority (220, 74.6%) described themselves as gay. Rwanda had the highest number of respondents (117, 39.7% of the total), followed by Nigeria, Ghana and South-Africa.

The majority of respondents reported having heard about PEP (234, 80.7%), and the average PEP correct knowledge level was 59%.

Five characteristics were associated with increased odds of using PEP: Age, having vocational education, having heard of PEP, knowledge of where to get PEP, and having been refused housing.

Conclusion

There is a need for a collaborative effort between policy makers, key players in HIV prevention, and MSM associations in SSA to remove barriers to PEP uptake to promote optimal PEP utilization amongst MSM.

Design Considerations for Implementing eHealth Behavioral Interventions for HIV Prevention in Evolving Sociotechnical Landscapes

PURPOSE OF REVIEW

Despite tremendous potential for public health impact and continued investments in development and evaluation, it is rare for eHealth behavioral interventions to be implemented broadly in practice. Intervention developers may not be planning for implementation when designing technology-enabled interventions, thus creating greater challenges for real-world deployment following a research trial. To facilitate faster translation to practice, we aimed to provide researchers and developers with an implementation-focused approach and set of design considerations as they develop new eHealth programs.

RECENT FINDINGS

Using the Accelerated Creation-to-Sustainment model as a lens, we examined challenges and successes experienced during the development and evaluation of four diverse eHealth HIV prevention programs for young men who have sex with men: Keep It Up!, Harnessing Online Peer Education, Guy2Guy, and HealthMindr. HIV is useful for studying eHealth implementation because of the substantial proliferation of diverse eHealth interventions with strong evidence of reach and efficacy and the responsiveness to rapid and radical disruptions in the field. Rather than locked-down products to be disseminated, eHealth interventions are complex sociotechnical systems that require continual optimization, vigilance to monitor and troubleshoot technological issues, and decision rules to refresh content and functionality while maintaining fidelity to core intervention principles. Platform choice and sociotechnical relationships (among end users, implementers, and the technology) heavily influence implementation needs and challenges. We present a checklist of critical implementation questions to address during intervention development. In the absence of a clear path forward for eHealth implementation, deliberate design of an eHealth intervention's service and technological components in tandem with their implementation plans is critical to mitigating barriers to widespread use. The design considerations presented can be used by developers, evaluators, reviewers, and funders to prioritize the pragmatic scalability of eHealth interventions in research.

Structural Interventions to Reduce and Eliminate Health Disparities

Health disparities research in the United States over the past 2 decades has yielded considerable progress and contributed to a developing evidence base for interventions that tackle disparities in health status and access to care. However, health disparity interventions have focused primarily on individual and interpersonal factors, which are often limited in their ability to yield sustained improvements. Health disparities emerge and persist through complex mechanisms that include socioeconomic, environmental, and system-level factors. To accelerate the reduction of health disparities and yield enduring health outcomes requires broader approaches that intervene upon these structural determinants. Although an increasing number of innovative programs and policies have been deployed to address structural determinants, few explicitly focused on their impact on minority health and health disparities. Rigorously evaluated, evidence-based structural interventions are needed to address multilevel structural determinants that systemically lead to and perpetuate social and health inequities. This article highlights examples of structural interventions that have yielded health benefits, discusses challenges and opportunities for accelerating improvements in minority health, and proposes recommendations to foster the development of structural interventions likely to advance health disparities research.

[Heterosexually active men, masculinities, HIV prevention, and the search for post-exposure prophylaxis following sexual exposure]

Hegemonic masculinity has distanced heterosexually active men from the responses to the HIV epidemic. However, with the combined prevention paradigm, post-exposure prophylaxis offers new ways to manage the risks of HIV infection, while at the same time bringing about new challenges. The aim of this paper is to discuss - through the lens of gender and masculinities - how heterosexually active men perceive their HIV risk and how they manage prevention methods and strategies, including post-exposure prophylaxis. Employing qualitative methods, 16 heterosexually active men in five health services from different Brazilian cities were interviewed. The analysis indicates that condom use - the main prevention method - was conditioned by subjective and contextual factors, and its failure stands out as the primary reason for seeking out post-exposure prophylaxis. We argue that ideals of hegemonic masculinity permeate perceptions and risk management discourses in the current context of the HIV/AIDS epidemic.

High Levels of Syndemics and Their Association with Adherence, Viral Non-suppression, and Biobehavioral Transmission Risk in Miami, a U.S. City with an HIV/AIDS Epidemic

Miami is a Southeastern United States (U.S.) city with high health, mental health, and economic disparities, high ethnic/racial diversity, low resources, and the highest HIV incidence and prevalence in the country. Syndemic theory proposes that multiple, psychosocial comorbidities synergistically fuel the HIV/AIDS epidemic. People living with HIV/AIDS in Miami may be particularly affected by this due to the unique socioeconomic context. From April 2017 to October 2018, 800 persons living with HIV/AIDS in a public HIV clinic in Miami completed an interviewer-administered behavioral and chart-review cross-sectional assessment to examine the prevalence and association of number of syndemics (unstable housing, low education, depression, anxiety, binge drinking, drug use, violence, HIV-related stigma) with poor ART adherence, unsuppressed HIV viral load (≥ 200 copies/mL), and biobehavioral transmission risk (condomless sex in the context of unsuppressed viral load). Overall, the sample had high prevalence of syndemics (M = 3.8), with almost everyone (99%) endorsing at least one. Each syndemic endorsed was associated with greater odds of: less than 80% ART adherence (aOR 1.64, 95% CI 1.38, 1.98); having unsuppressed viral load (aOR 1.16, 95% CI 1.01, 1.33); and engaging in condomless sex in the context of unsuppressed viral load (1.78, 95% CI 1.30, 2.46). The complex syndemic of HIV threatens to undermine the benefits of HIV care and are important to consider in comprehensive efforts to address the disproportionate burden of HIV/AIDS in the Southern U.S. Achieving the 90-90-90 UNAIDS and the recent U.S. "ending the epidemic" targets will require efforts addressing the structural, social, and other syndemic determinants of HIV treatment and prevention.

Thematic synthesis HIV prevention qualitative studies in men who have sex with men (MSM)

BACKGROUND

Qualitative studies on HIV prevention strategies and methods among men who have sex with men (MSM) allow identify knowledge gaps and improve preventive actions.

OBJECTIVE

To make a thematic synthesis of the scientific productions that use the qualitative methodology in the strategies and methods of HIV prevention area among MSM.

METHODS

We conducted a literature review following the guidelines of the ENTREQ protocol. The analysis included 48 empirical studies published in Portuguese, English and Spanish between 2001 and 2018 available in the Medline, Embase, Scielo, Scopus, Bireme and Web of Science databases.

RESULTS

Where an increased production in the last six years and concentration in northern countries. Seven prevention methods were part of the study, with emphasis on pre-exposure prophylaxis, testing, condoms and behavioral strategies. The main topics discussed were stigma and support and care networks.

CONCLUSION

we notice that an increasing production on prevention in the men who have sex with men segment results from the emergence of multiple preventive methods and strategies and their combined actions beyond the star role of condoms.

Text-Messaging, Online Peer Support Group, and Coaching Strategies to Optimize the HIV Prevention Continuum for Youth: Protocol for a Randomized Controlled Trial

BACKGROUND

America's increasing HIV epidemic among youth suggests the need to identify novel strategies to leverage services and settings where youth at high risk (YAHR) for HIV can be engaged in prevention. Scalable, efficacious, and cost-effective strategies are needed, which support youth during developmental transitions when risks arise. Evidence-based behavioral interventions (EBIs) have typically relied on time-limited, scripted, and manualized protocols that were often delivered with low fidelity and lacked evidence for effectiveness.

OBJECTIVE

This study aims to examine efficacy, implementation, and cost-effectiveness of easily mountable and adaptable, technology-based behavioral interventions in the context of an enhanced standard of care and study assessments that implement the guidelines of Centers for Disease Control and Prevention (CDC) for routine, repeat HIV, and sexually transmitted infection (STI) testing for high-risk youth.

METHODS

Youth aged between 12 and 24 years (n=1500) are being recruited from community-based organizations and clinics serving gay, bisexual, and transgender youth, homeless youth, and postincarcerated youth, with eligibility algorithms weighting African American and Latino youth to reflect disparities in HIV incidence. At baseline and 4-month intervals over 24 months (12 months for lower-risk youth), interviewers monitor uptake of HIV prevention continuum steps (linkage to health care, use of pre- or postexposure prophylaxis, condoms, and prevention services) and secondary outcomes of substance use, mental health, and housing security. Assessments include rapid diagnostic tests for HIV, STIs, drugs, and alcohol. The study is powered to detect modest intervention effects among gay or bisexual male and transgender youth with 70% retention. Youth are randomized to 4 conditions: (1) enhanced standard of care of automated text-messaging and monitoring (AMM) and repeat HIV/STI testing assessment procedures (n=690); (2) online group peer support via private social media plus AMM (n=270); (3) coaching that is strengths-based, youth-centered, unscripted, based on common practice elements of EBI, available over 24 months, and delivered by near-peer paraprofessionals via text, phone, and in-person, plus AMM (n=270); and (4) online group peer support plus coaching and AMM (n=270).

RESULTS

The project was funded in September 2016 and enrollment began in May 2017. Enrollment will be completed between June and August 2019. Data analysis is currently underway, and the first results are expected to be submitted for publication in 2019.

CONCLUSIONS

This hybrid implementation-effectiveness study examines alternative models for implementing the CDC guidelines for routine HIV/STI testing for YAHR of acquiring HIV and for delivering evidence-based behavioral intervention content in modular elements instead of scripted manuals and available over 24 months of follow-up, while also monitoring implementation, costs, and effectiveness. The greatest impacts are expected for coaching, whereas online group peer support is expected to have lower impact but may be more cost-effective.

Primary prevention

HIV infection is still not controlled in Spain. New HIV infection prevention strategies are required, especially in populations of higher incidence, by means of combined interventions. Early diagnosis and treatment of HIV-infected individuals is the most cost-effective strategy to control the epidemic, including interventions designed to motivate behavioural changes. These types of campaigns must not only be directed to the general population through mass channels, but also to key populations through more specific channels and messages. Biomedical interventions like pre-exposure prophylaxis, uses a combination of biomedical tools to reduce the risk of HIV acquisition, and are usually accompanied of behavioural interventions. The influence of structural factors, social justice and defending the rights of people living with HIV have a significant impact on prevention strategies. Structural interventions are designed to influence these factors that make some individuals or populations more vulnerable to HIV infection.

Modeling economic and epidemiological impact of voluntary medical male circumcision among men who have sex with men in Beijing, China

Voluntary medical male circumcision (VMMC) among men who have sex with men (MSM) may protect against HIV acquisition. We conducted a series of analyses to assess if expanded VMMC might reduce HIV incidence among MSM effectively and economically. We used a deterministic compartmental model to project new HIV cases (2016-2026) under annual VMMC coverage rates (λ) ranging from 0.0001 to 0.15. The 'number needed to avert' (NNA) is defined as the cumulative number of VMMCs conducted up to that year divided by the cumulative number of HIV cases averted in that specific year. Compared with the baseline circumcision coverage rate, we projected that new HIV cases would be reduced with increasing coverage. By 2026 (last year simulated), the model generated the lowest ratio (11.10) when the annual circumcision rate was the most optimistic (λ = 0.15). The breakeven point was observed at the year of 2019 with the annual VMMC coverage rate of 0.001. The total cost saved by averting HIV cases would range from 2.5 to 811 million US dollars by the end of 2026 with different hypothetical coverage rates. Our model suggests that acceleration in VMMC implementation among MSM could help stem the HIV/AIDS epidemic.

Acceptability and Feasibility of Self-Collecting Biological Specimens for HIV, Sexually Transmitted Infection, and Adherence Testing Among High-Risk Populations (Project Caboodle!): Protocol for an Exploratory Mixed-Methods Study

BACKGROUND

Men who have sex with men (MSM) in the United States experience a disproportionate burden of HIV and bacterial sexually transmitted infections (STIs), such as gonorrhea and chlamydia. Screening levels among MSM remain inadequate owing to barriers to testing such as stigma, privacy and confidentiality concerns, transportation issues, insufficient clinic time, and limited access to health care. Self-collection of specimens at home and their return by mail for HIV and bacterial STI testing, as well as pre-exposure prophylaxis (PrEP) adherence monitoring, could be a resource-efficient option that might mitigate some of these barriers.

OBJECTIVE

Project Caboodle! is a mixed-methods study that explores the acceptability and feasibility of self-collecting and returning a bundle of 5 different specimens for HIV and bacterial STI testing, as well as PrEP adherence monitoring, among sexually active HIV-negative or unknown status MSM in the United States aged 18 to 34 years.

METHODS

Participants will be recruited using age, race, and ethnicity varied advertising on social networking websites and mobile gay dating apps. In Phase 1, we will send 100 participants a box containing materials for self-collecting and potentially returning a finger-stick blood sample (for HIV testing), pharyngeal swab, rectal swab, and urine specimen (for gonorrhea and chlamydia testing), and hair sample (to assess adequacy for potential PrEP adherence monitoring). Specimen return will not be incentivized, and participants can choose to mail back all, some, or none of the specimens. Test results will be delivered back to participants by trained counselors over the phone. In Phase 2, we will conduct individual in-depth interviews using a video-based teleconferencing software (VSee) with 32 participants from Phase 1 (half who returned all specimens and half who returned some or no specimens) to examine attitudes toward and barriers to completing various study activities.

RESULTS

Project Caboodle! was funded in May 2018, and participant recruitment began in March 2019. The processes of designing a study logo, creating advertisements, programming Web-based surveys, and finalizing step-by-step written instructions accompanied by color images for specimen self-collection have been completed. The boxes containing 5 self-collection kits affixed with unique identification stickers are being assembled, and shipping procedures (for mailing out boxes to participants and for specimen return by participants using prepaid shipping envelopes) and payment procedures for completing the surveys and in-depth interviews are being finalized.

CONCLUSIONS

Self-collection of biological specimens at home and their return by mail for HIV and bacterial STI testing, as well as PrEP adherence monitoring, might offer a practical and convenient solution to improve comprehensive prevention efforts for high-risk MSM. The potentially reduced time, expense, and travel associated with this approach could facilitate a wider implementation of screening algorithms and remote monitoring strategies.

Creating a Theoretically Grounded Gaming App to Increase Adherence to Pre-Exposure Prophylaxis: Lessons From the Development of the Viral Combat Mobile Phone Game

BACKGROUND

In the United States, young minority men who have sex with men (MSM) are most likely to become infected with HIV. The use of antiretroviral medications to reduce the risk of acquiring HIV infection (pre-exposure prophylaxis, PrEP) is an efficacious and promising prevention strategy. There have been significant advances regarding PrEP, including the definitive demonstration that PrEP reduces HIV acquisition and the development of clinical prescribing guidelines. Despite these promising events, the practical implementation of PrEP can be challenging. Data show that PrEP's safety and effectiveness could be greatly compromised by suboptimal adherence to treatment, and there is concern about the potential for an increase in HIV risk behavior among PrEP users. Due to these challenges, the prescribing of PrEP should be accompanied by behavioral interventions to promote adherence.

OBJECTIVE

This study aimed to develop an immersive, action-oriented iPhone gaming intervention to improve motivation for adherence to PrEP.

METHODS

Game development was guided by social learning theory, taking into consideration the perspectives of young adult MSM who are taking PrEP. A total of 20 young men who have sex with men (YMSM; aged 18-35 years) were recruited from a sexually transmitted infection (STI), HIV testing, and PrEP care clinic in Jackson, Mississippi, between October 2016 and June 2017. They participated in qualitative interviews guided by the information-motivation-behavioral skills (IMB) model of behavior change. The mean age of participants was 26 years, and all the participants identified as male. Acceptability of the game was assessed with the Client Service Questionnaire and session evaluation form.

RESULTS

A number of themes emerged that informed game development. YMSM taking PrEP desired informational game content that included new and comprehensive details about the effectiveness of PrEP, details about PrEP as it relates to doctors' visits, and general information about STIs other than HIV. Motivational themes that emerged were the desire for enhancement of future orientation; reinforcement of positive influences from partners, parents, and friends; collaboration with health care providers; decreasing stigma; and a focus on personal relevance of PrEP-related medical care. Behavioral skills themes centered around self-efficacy and strategies for adherence to PrEP and self-care.

CONCLUSIONS

We utilized youth feedback, IMB, and agile software development to create a multilevel, immersive, action-oriented iPhone gaming intervention to improve motivation for adherence to PrEP. There is a dearth of gaming interventions for persons on PrEP. This study is a significant step in working toward the development and testing of an iPhone gaming intervention to decrease HIV risk and promote adherence to PrEP for YMSM.

Incidence and risk factors for tenofovir-associated nephrotoxicity among human immunodeficiency virus-infected patients in Korea

BACKGROUND/AIMS

Little is known about tenofovir disoproxil fumarate (TDF)-induced nephrotoxicity in human immunodeficiency virus (HIV)-infected patients in Korea. The objective of this study was to evaluate the incidence and risk factors of TDF-associated nephrotoxicity among HIV-infected patients in Korea.

METHODS

A single-center retrospective cohort study was conducted on HIVinfected patients in Korea. We included patients who had started TDF or abacavir (ABC)-based antiretroviral therapy (ART) between October 2006 and December 2014. Estimated glomerular filtration rate (eGFR) was estimated using the Chronic Kidney Disease-Epidemiology Collaboration equation. Renal dysfunction was defined as > 25% decrease of baseline eGFR. A propensity matched case-control study was conducted to compare renal dysfunction rates between the two groups. The risk factors of nephrotoxicity were analyzed by Cox regression analysis.

RESULTS

A total of 210 HIV-infected patients were included in the study, of which, 108 were TDF-based ART group and 102 were ABC-based ART group. Renal dysfunction occurred in 16 patients (14.8%) in the TDF group and 11 (10.8%) in the ABC group. Incidence of renal dysfunction of TDF and ABC group was 9.66 per 100 person-years (PYs) and 5.14 per 100 PYs, respectively (p = 0.176). In propensityscore-matched analysis, renal dysfunction rates were TDF 13.3% versus ABC 13.3% (p > 0.999). In multivariable analysis, Centers for Disease Control and Prevention clinical category C was a significant risk factor for renal dysfunction.

CONCLUSION

Approximately, 13% of HIV-infected patients treated with TDF had renal dysfunction. Advanced stage of HIV infection was a significant risk factor for renal dysfunction.

Interprofessional Collaboration and On-the-Job Training Improve Access to HIV Testing, HIV Primary Care, and Pre-Exposure Prophylaxis (PrEP)

The HIV Continuum of Care is a global priority, yet vulnerable patients face access/retention challenges. Research is missing on the role social and public health service providers can play to help these patients. Using structural equation modeling, we examined the effects of interprofessional collaboration (IPC) and on-the-job training on the frequency of linkages to HIV testing, HIV primary care, and on pre-exposure prophylaxis (PrEP) psychoeducation. The sample included 285 New York City providers of social and public health services from 34 agencies. Forty-eight percent of providers had not offered PrEP psychoeducation and linked fewer than five patients to HIV testing and primary care per week. However, in multivariate analysis higher IPC was associated with more linkages and frequent psychoeducation. After adjusting for IPC, linkage training was associated with more frequent services. The influence of specific factors highlights areas for interventions and policies to improve access to the HIV Continuum of Care.

Factors associated with the utilization of antenatal care and prevention of mother-to-child HIV transmission services in Ethiopia: applying a count regression model

BACKGROUND

Prevention of Mother-to-Child HIV Transmission (PMTCT) coverage has been low in Ethiopia and the service has been implemented in a fragmented manner. Solutions to this problem have mainly been sought on the supply-side in the form of improved management and allocation of limited resources. However, this approach largely ignores the demand-side factors associated with low PMTCT coverage in the country. The study assesses the factors associated with the utilization of PMTCT services taking into consideration counts of visits to antenatal care (ANC) services in urban high-HIV prevalence and rural low-HIV prevalence settings in Ethiopia.

METHODS

A multivariate regression model was employed to identify significant factors associated with PMTCT service utilization. Poisson and negative binomial regression models were applied, considering the number of ANC visits as a dependent variable. The explanatory variables were age; educational status; type of occupation; decision-making power in the household; living in proximity to educated people; a neighborhood with good welfare services; location (urban high-HIV prevalence and rural low-HIV prevalence); transportation accessibility; walking distance (in minutes); and household income status. The alpha dispersion test (a) was performed to measure the goodness-of-fit of the model. Significant results were reported at p-values of < 0.05 and < 0.001.

RESULTS

Household income, socio-economic setting (urban high-HIV prevalence and rural low-HIV prevalence) and walking distance (in minutes) had a statistically significant relationship with the number of ANC visits by pregnant women (p < 0.05). A pregnant woman from an urban high-HIV prevalence setting would be expected to make 34% more ANC visits (counts) than her rural low-HIV prevalence counterparts (p < 0.05). Holding other variables constant, a unit increase in household income would increase the expected ANC visits by 0.004%. An increase in walking distance by a unit (a minute) would decrease the number of ANC visits by 0.001(p < 0.001).

CONCLUSION

Long walking distance, low household income and living in a rural setting are the significant factors associated with low PMTCT service utilization. The primary strategies for a holistic policy to improve ANC/PMTCT utilization should thus include improving the geographical accessibility of ANC/PMTCT services, expanding household welfare and paying more attention to remote rural areas.

Hispanic Students' Perceptions About HIV/STI Testing and Prevention: A Mixed-Methods Study in a Hispanic-Serving University

Hispanic young adults in the United States are disproportionately affected by HIV and should be considered a priority for prevention efforts. The purpose of this study was to explore perceptions and beliefs of English-speaking students (aged 18-24 years) at a Hispanic-serving university about HIV/sexually transmitted infection (STI) testing and prevention to increase acceptance and adoption of services. Four major themes emerged from four qualitative focus groups (n = 30 students) and were corroborated by an optional anonymous survey (n = 24 surveys): (a) preferences for HIV/STI testing services, (b) essential HIV/STI testing information, (c) preferred delivery method of HIV/STI testing information, and (d) culturally appropriate message design with Hispanic young adults. Findings suggest that Hispanic young adults perceive accessible testing to be important to their community and view normalization of these services as a necessary component of successful adoption and adherence. Although flyers were reported as a practical means for distributing on-campus testing and service information, social media was endorsed as one of the most effective ways to reach young adults. Among participants, there was less consensus regarding the need for cultural tailoring. Results provide practical insights into the development and application of health promotion strategies with an ethnic minority group and demonstrate how a mixed-methods approach can be employed to inform health promotional efforts.

The Relationship Between Psychological Temporal Perspective and HIV/STI Risk Behaviors Among Male Sex Workers in Mexico City

Men who have sex with men (MSM) face a disproportionate burden of HIV incidence and HIV prevalence, particularly young men who have sex with men. The aim of this article was to analyze the relation between a psychological temporal perspective and HIV/sexually transmitted infection (STI) risk behaviors among male sex workers (MSWs), a potentially highly present-oriented group of MSM. A total sample of 326 MSWs were included and responded to a validated psychological scale: the Zimbardo's Time Perspective Inventory; they also reported how frequently they engaged in protective behaviors against HIV and other STI risks behaviors, including condom use with casual and regular partners, as well as prior HIV testing. We adjusted structural equation models to analyze the relation between a psychological temporal perspective and HIV/STI risk behaviors. We found that orientation toward the past was correlated with decreased condom use with casual partners (β = - 0.18; CI_95% - 0.23, - 0.12). Future orientation was not associated with condom use with casual partners. Regarding condom use with regular partners, past and present orientation were related to lower likelihood of condom use (β = - 0.23; CI_95% - 0.29, - 0.17; β = - 0.11; CI_95% - 0.19, - 0.02), whereas future orientation increased the likelihood of condom use with regular partners (β = 0.40; CI_95% 0.31, 0.50). Time orientation (past, present, or future) did not predict the probability of having an HIV test. The design of HIV/STI prevention programs among vulnerable populations, such as MSM and MSWs, should consider specific time-frame mechanisms that can importantly affect sexual risk behavior decisions.
