Vital Voices: HIV Prevention and Care Interventions Developed for Disproportionately Affected Communities by Historically Underrepresented, Early-Career Scientists.

BACKGROUND: HIV prevention interventions which support engagement in care and increased awareness of biomedical options, including pre-exposure prophylaxis (PrEP), are highly desired for disproportionately affected Black/African American, Hispanic/Latinx and gay, bisexual, and other men who have sex with men (GBMSM) populations in the United States (US). However, in almost 40 years of HIV research, few interventions have been developed directly by and for these priority populations in domestic counties most at risk. We submit that interventions developed by early-career scientists who identify with and work directly with affected subgroups, and which include social and structural determinants of health, are vital as culturally tailored HIV prevention and care tools.
METHODS: We reviewed and summarized interventions developed from 2007 to 2020 by historically underrepresented early-career HIV prevention scientists in a federally funded research mentoring program. We mapped these interventions to determine which were in jurisdictions deemed as high priority (based on HIV burden) by national prevention strategies.
RESULTS: We summarized 11 HIV interventions; 10 (91%) of the 11 interventions are in geographic areas where HIV disparities are most concentrated and where new HIV prevention and care activities are focused. Each intervention addresses critical social and structural determinants of health disparities, and successfully reaches priority populations.
CONCLUSION: Focused funding that supports historically underrepresented scientists and their HIV prevention and care intervention research can help facilitate reaching national goals to reduce HIV-related disparities and end the HIV epidemic. Maintaining these funding streams should remain a priority as one of the tools for national HIV prevention.

Introduction

Although Blacks/African Americans (Blacks thereafter) and Hispanics/Latinxs (Latinxs thereafter) jointly constituted an estimated 31% of the United States (US) population [1], they accounted for an estimated 70% of HIV diagnoses in 2018 [2]. The disparate HIV morbidity and mortality burden among Blacks and Latinxs are seen in each region of the US (although more so in the southern US) and within each major transmission risk category/subgroup, including gay, bisexual, and other men who have sex with men (GBMSM), men, and women of transgender experience, women and men exposed through heterosexual contact, sexually active youth, people who use drugs, and infants exposed through perinatal transmission. In fact, Black/African American GBMSM accounted for 26% of new HIV diagnoses and 37% of new diagnoses among all gay and bisexual men in the US; Hispanic/Latino GBMSM made up 21% of new HIV diagnoses in the US. Efforts to address these alarming HIV-related health disparities have included trainings, mentoring programs, and career development awards designed to help build a more diverse and culturally-experienced scientific and clinical workforce [3-5]. Early-career scientists with a commitment to these communities, particularly historically underrepresented minority scientists, are vital for the development and evaluation of culturally appropriate HIV interventions to reduce HIV disparities.

Recent data underscore that domestic HIV prevention and treatment efforts should be more geographically targeted. During 2016 and 2017, half of the new HIV diagnoses were concentrated in Washington, DC, Puerto Rico and 48 of the 3007 counties in the US [6, 7]. Also in 2017, 52% of HIV diagnoses were in southern states, including several rural southern states, although these states comprise only 38% of the US population [6, 7]. The South accounts for the majority of Blacks newly diagnosed with HIV (63% in 2017) and Blacks living with an HIV diagnosis at the end of 2016 (58%). Among Latinxs, the data are also alarming; 25% of new HIV infections in the US occur among Latinx [8]. Latinx GBMSM are the only subgroup experiencing an increase in new diagnoses compared with other groups in recent years [8, 9].

Several reports underscore that minority scientists’ sociocultural insights and personal commitment augment our collective capacity to develop relevant questions and programs for highly affected communities [3–5, 10–15]. Several senior federal officials suggest that HIV research conducted by investigators who resemble affected communities strengthens the understanding of cultural and contextual issues that may enhance the utility and generalizability of specific findings and interventions [14-16]. For HIV, scientific contributions from Black, Latinx, same-gender loving, and transgender scientists are warranted based on the epidemiology of the domestic HIV epidemic, yet these scientists remain underrepresented [16, 17]. Also, federal data show that research grant applications from investigators of color are less likely to be funded for federal research compared with those from non-Hispanic white peers; targeted scientific research programs that support and mentor historically underrepresented scientists have been suggested as one federal, policy-level solution [18].

Of the diversity-focused HIV training and research programs in the US, one is funded by the Centers for Disease Control and Prevention (CDC)—The Minority HIV/AIDS Research Initiative (MARI). MARI, funded initially in 2003, is a mentored training program for underrepresented, early-career minority scientists conducting HIV prevention research in highly affected racial/ethnic and sexual minority communities (https://www.cdc.gov/hiv/dhap/eb/mari/index.html). The program is one of the few in the US that assists early-career minority investigators through mentoring, training, and funding to conduct high impact, innovative HIV research and increase diversity of the scientific workforce. It is the only HIV research mentoring program in the US that funds investigators as lead principal investigators (PIs), thus allowing for the necessary protected time, academic support, and hiring of team members to fully implement impactful studies [4]. Details about the program have been published previously [4, 11]. MARI’s annual budget (~ $2 million dollars) is less than 1% of the CDC’s Division of HIV/AIDS Prevention’s annual domestic spending [4]. To date, MARI has been announced as a mentoring grant four times: 2003, 2007, 2011, and 2016, and funded 37 grantees. Previously published MARI reports did not include information about HIV interventions developed by MARI scientists [4, 11]. However, effective interventions have become more vital as the country continues to build on the progress of the first-ever National HIV/AIDS Strategy started in 2010 [19] and towards national HIV prevention goals of “reducing the number of new HIV infections in the United States by 75 percent within five years, and then by at least 90 percent within 10 years, for an estimated 250,000 total HIV infections averted” [6, 7].

In this report, we (1) describe several social and structural determinants of health (SSDoH) that inform disparities in HIV prevention and care in affected communities, particularly in the southern US and among Black and Latinx GBMSM, (2) summarize the HIV prevention and treatment interventions developed or in progress by MARI grantees, and (3) make the case for efforts like MARI in disproportionately affected communities. Dissemination of HIV prevention and care interventions to priority populations is strengthened when those strategies are culturally tailored [20].

Social and Structural Determinants of Health and Disparities in HIV Prevention and Care

As Black and Latinx GBMSM remain disproportionately affected by HIV, especially in high-prevalence geographic areas in the US, most MARI PIs have conducted epidemiologic research to inform efforts that strengthen HIV prevention and care for Black and Latinx GBMSM in these geographic areas. Several reports underscore the impact of SSDoH on GBMSM populations’ prevention and care strategies and the importance of targeting them in interventions, including 2-fold greater odds of Black and Latinx GBMSM having any structural barrier that increases HIV risk (e.g., education; history of incarceration; low income; pervasive racism and discrimination; housing insecurity, homelessness and displacement; anti-immigration policies and laws; unemployment; lack of insurance) [21], the role of self-efficacy, hardiness/adaptive coping/resilience, and effective transition to adulthood in protecting young, GBMSM from HIV-related risks [22-27]; the importance of medical mistrust, of culturally competent clinical services, and Medicaid expansion for HIV-related care among Black GBMSM, especially in the southern US [28]; and the prevalence of stigma, childhood sexual trauma, mental health stressors, including antihomosexual expectations of masculinity and racism for Black and Latinx GBMSM as HIV risk factors, barriers to HIV care and pre-exposure prophylaxis (PrEP) for prevention [29, 30]. MARI PIs have also focused on Black and Latinx heterosexual youth and the context of family support [31], geographical risks [32], and social-cognitive relationship factors [33] on sexual behaviors and risks. Addressing these SSDoH factors as HIV prevention and care interventions are being developed is a key component to improving their acceptability within some highly affected Black and Latinx communities.

Interventions Developed by MARI Investigators

From 2007 to 2020, 11 MARI investigators developed HIV prevention interventions based on primary data collected from persons in affected communities. Importantly, 10 (91%) of the 11 interventions that are being developed or already implemented are in one of the priority 48 counties or seven states based on new HIV diagnoses (see Fig. 1) [6, 7]. Table 1 summarizes the interventions by PI’s names, years of funding, title of the intervention, key publications and presentations that describe the methods of the intervention and/or the main outcome findings, and intervention session details. The interventions (completed and in-progress) are described below. All studies and interventions described were reviewed and approved by each institution’s local or private Internal Review Board (IRB).

Completed Interventions

Familias Unidas (Developed in Miami, FL; 2007–2011)

Familias Unidas is a culturally-specific, family-based intervention for Latinx youth and their families. Informed by ecodevelopmental theory [34], Familias Unidas aims to prevent substance use, unprotected sexual behavior, and sexually transmitted infection (STI) incidence by increasing positive parenting, family support of the adolescent, and parental involvement, as well as by improving parent-adolescent communication. Familias Unidas is delivered through family-centered, multi-parent groups that place parents in the change agent role and through family sessions where parents have an opportunity to practice the skills learned in the group sessions with their own youth. Familias Unidas has been evaluated and found to be efficacious and effective in preventing and reducing substance use, externalizing disorders, sexual risk behaviors, internalizing symptoms, and suicidal behavioral outcomes in multiple CDC and NIH funded studies [35-40]. The intervention is listed in a number of evidence-based registries, including CDC’s Compendium of Evidence-based Interventions (Available at: https://www.cdc.gov/hiv/research/interventionresearch/compendium/index.html), and is currently being disseminated in other parts of the US and the world including Providence, RI; Chester County, PA; Guayaquil, Ecuador; and Santiago, Chile. Additional Familias Unidas details are available: https://www.cdc.gov/hiv/pdf/research/interventionresearch/compendium/Familias_Unidas_BEST_RR.pdf.

eHealth Familias Unidas (developed in Miami, FL; 2011–2016) is an online family intervention designed to prevent drug use and sexual risk behaviors (condomless sex) among Latinx adolescents. eHealth Familias Unidas was adapted onto an Internet platform (informed by increased use of the internet and cell phones by priority populations) based on its face-to-face version, Familias Unidas [31, 35, 41]. We tested the efficacy of eHealth Familias Unidas in a randomized controlled trial with 230 Latinx families [42]. Families were assessed and randomized to eHealth Familias Unidas or prevention as usual. Researchers conducted follow-up assessments at 3 and 12 months post-baseline. Positive intervention effects were found for drug use including, past 90 day marijuana use, inhalant use, and prescription drug use. Additionally, the intervention improved family functioning. Intervention effects were not found for condom use. The lack of findings for condom use is likely due to a shorter than normal follow-up period. Previous Familias Unidas trials have found condom use intervention effects at longer follow-ups [43]. eHealth Familias Unidas is currently being tested across pediatric primary care settings via an effectiveness trial.

Project GOLD: We Are Kings and Queens (Developed in Philadelphia, PA; 2011–2016)

Project GOLD was developed in an iterative, community-engaged process to account for the role of mental health and emotion regulation in sexual risk behaviors among heterosexually-active Black youth aged 14 to 17 years [44]. The intent is to build skills to negotiate consistent condom use, limit the number of sexual partners, encourage HIV testing, and promote abstinence as an alternative to unwanted sexual activity. In addition to evidence-based HIV/STI prevention strategies (e.g., condom use technical skills), the activities are rooted in principles of Cognitive Behavioral Therapy. This includes fun, interactive strategies to help participants negotiate safer sexual practices—particularly in the face of distorted cognitions and elevated psychological symptoms. Although not statistically significant, compared to the general health condition (n = 56), those in the HIV/STI prevention condition (n = 52) reported a higher proportion of condom use (M = 0.77 vs. M = 0.64) and fewer sexual partners (M = 1.79 vs. M = 4.17) at 3 months. The lack of statistical significance may have been due to the pilot study’s small sample size at the follow-up periods. Future testing in an adequately powered optimization trial is planned. Alongside the intervention activities, the research team established a precedent for youth participation in sexual health research without parental consent to protect their confidentiality and ensure the representative advancement of HIV/STI prevention science [45]. Additional information on Project GOLD is here: https://clinicaltrials.gov/ct2/show/NCT03348813?titles=Project+GOLD&rank=1.

Metropolitan Atlanta Community Adolescent Rapid Testing Initiative (MACARTI) (Developed in Atlanta, GA; 2011–2016)

The MACARTI intervention was designed to utilize non-traditional venue HIV testing, motivational interviewing (MI), and case management (CM) support to increase identification, linkage, and retention in care of newly diagnosed HIV-positive youth between the ages 18–24 years in Atlanta. A formative phase consisted of focus groups with HIV-positive and HIV-negative youth to understand HIV testing preferences and potential venues for testing [46]. Participant responses were used to develop a youth-friendly testing strategy, to select testing sites, and to better characterize post-diagnosis support [47]. During the intervention phase, MACARTI screened 435 participants and identified 49 (11.3%) newly HIV-positive youth. The standard of care arm (SOC) enrolled 49 new HIV-positive individuals for comparison. Overall, 63% were linked within 3 months of diagnosis; linkage was higher for MACARTI compared with SOC (96% vs. 57%, p < 0.001) [48]. Median linkage time for MACARTI participants compared to SOC was 0.39 (IQR: 0.20–0.72) vs. 1.77 (IQR: 1.12–12.65) months (p < 0.001) and MACARTI appointment adherence was higher than SOC (86.1% vs. 77.2%, p = 0.018) [48]. MACARTI successfully identified HIV-positive youth in the community and utilized MI and CM to address behavioral, motivational, and socioeconomic factors that affect HIV care effectively decreasing gaps for youth along the HIV care continuum. After study enrollment, the MACARTI team continued to effectively link and retain an additional 91 newly identified HIV-positive youth.

Project FAITHH (Developed in Tuscaloosa, AL; 2011–2016)

Project Faith-based Anti-stigma Initiative Towards Healing HIV/AIDS (FAITHH) is an HIV stigma-reduction intervention which was developed as a collaborative effort with rural, southern faith leaders from various denominations [49]. We measured HIV-related stigma held by 199 adults (church members) who participated in the intervention (individual-level) and their perception of stigma among other congregants (congregational-level). Analyses of pre- and post-assessments showed the anti-stigma intervention group reported a significant reduction in individual-level stigma compared with the control group (mean difference: − 0.70 intervention vs. − 0.16 control, adjusted p < 0.05) [50]. Engaging faith leaders facilitated the successful tailoring of the intervention, and congregation members were willing participants in the research process. Findings suggest African American churches may be poised to support HIV stigma-reduction efforts. Since 2016, a public website was developed and more than 300 manuals of the intervention have been distributed to HIV service organizations and staff persons, health department officials, and church leaders. Additional information is available at: https://projectfaithh.ua.edu/.

Contacto (Developed in San Juan, Puerto Rico; 2011–2016)

The goal of this intervention was to improve health outcomes (i.e., HIV status or sexual orientation/gender identity disclosure, engagement in healthcare) by addressing the negative impact of social stigma among HIV-positive Spanish-speaking GBMSM. Contacto was developed after formative research with the community [26] and is the first HIV intervention sponsored by CDC completely developed in Spanish for Spanish-speaking populations by bilingual (Spanish and English) and native Spanish-speaking scientists. A total of 109 men participated in the feasibility, acceptability, and preliminary efficacy assessment of Contacto. The retention rate of the intervention was 95%. Following a pre-post-post design at 6 weeks (at booster session) and 3 months from baseline, we documented significant reductions in felt-HIV stigma, perceived-gay stigma, internalized gay stigma, and internalized homonegativity (p < 0.05) [51]. Findings also suggest a decrease in depression symptomatology and an increase in HIV disclosure, social support, and overall quality of life. Based on these findings, two iterations of the intervention are being developed: Contactos (group-level) and Contacta-dos (couples-level).

In-Progress Interventions

Brothers Building Brothers by Breaking Barriers (B6) (Developed in Atlanta, GA; 2016–2020)

B6 was developed based on the scientific premise that social capital [52]—defined here as the sum of resources an individual derives from his/her social network—is a significant resilience resource that can improve engagement in care for people living with HIV. The objective of B6 is to increase social capital for young Black gay, bisexual, and other men who have sex with men (YB-GBMSM) who are HIV-positive, as a means to improve care engagement and mental health outcomes. The group-level intervention was developed through an iterative community-based participatory research process [53, 54], in collaboration with a youth advisory board composed of HIV-positive YB-GBMSM and a separate community advisory board composed of local HIV advocates. Rather than focusing exclusively on HIV, B6 takes a holistic approach to supporting YB-GBMSM. Activities aim to explore and affirm Black gay identity, build skills in critical self-reflection, and teach effective communication skills for navigating family, relationships, and clinical and professional settings. B6 is currently being tested in a randomized controlled trial (NCT03664817); 60 participants have gone through the B6 or control condition to date (of a planned 120). In anonymous post-intervention surveys, participants have shared that they enjoyed “meeting new people, gaining new resources”, had fun, learned about themselves, and that their “social network expanded.”

Project YESS! (Youth Engaging in Healthy and Safe Sex; Developed in New York, NY; 2016–2020)

The objective of Project YESS! is to develop a scalable, culturally tailored and developmentally appropriate couple-level intervention to increase uptake of biomedical combination HIV prevention methods (i.e., correct and consistent and correct condom use, STI screening and treatment, routine regular HIV testing and linkage to care, and initiation of and adherence to PrEP) among Black and Latino heterosexual couples living in vulnerable geographic areas. The formative phase consisted of in-depth individual and dyadic interviews and prospective quantitative surveys completed by both couple members. Black and Latino youth aged 16 to 24 and their nominated romantic partners are recruited from the South Bronx and Upper Manhattan, two communities with elevated poverty and high local HIV/STI prevalences [55]. Preliminary findings have led to important insights into the following: (1) the feasibility of engaging adolescent and young adult heterosexual couples in HIV prevention research, (2) characteristics of young couples’ romantic relationships, and (3) individual and interactive effects of social-cognitive and relationship factors on young couples’ sexual behavior and practices [33]. Intervention development is underway.

Contactos (Developed in San Juan, Puerto Rico; 2016–2020)

Contactos is an adaptation from Contacto into a group-level intervention. The adaptation followed the ADAPT-IT [56] model. A total of 32 HIV-positive young GBMSM ages 16 to 29 years, sexually active, Spanish-speakers, and Puerto Rico residents participated in qualitative formative focus groups and interviews [57]. We are implementing the intervention in collaboration with two local community-based organizations (CBOs) that provide LGBT and HIV-related services. Contactos consists of three biweekly 2.5-h sessions. Participants discuss topics regarding their experiences as young GBMSM with HIV, gay and HIV stigmas, healthcare access, and remaining in treatment, among others. MI-trained facilitator and co-facilitator assist participants identifying an area related to their health that they would like to improve or change. To evaluate the objectives of the intervention, participants complete three web-based assessments: (1) prior to the first session, (2) during the last session, and (3) 3 months from baseline (after first session). To date, six participants have completed the intervention.

Connecting Latinos en Pareja (CLP) (Developed in Philadelphia, PA; 2016–2020)

The overall objective of this intervention is to promote healthy relationships among Latino/Latinx, Afro-Latino/Afro-Latinx, and/or Latinx men in same-sex relationships in Philadelphia and surrounding areas [58]. Enrolled male couples receive information, resources, and learn skills with the goal of improving their sexual health, overall well-being, and strengthening their communication. CLP consists of four sessions whose content, scenarios, and examples can be adapted to each couple’s unique circumstances and relative HIV statuses. It incorporates biomedical prevention methods such as pre-exposure prophylaxes (PrEP); promotes engagement in care, adherence to treatment regimens and viral suppression; and encourages routine HIV testing as indicated by the couple’s serostatus. To date, 41 couples have completed intervention sessions and session attendance rates are 100% regardless of condition. Details about the ongoing study are available here: http://latinosenpareja.com/ .

HIV Information for Minority Men or For HIMM (Developed in Providence, RI and Boston, MA; 2016–2020)

For HIMM is a theoretically based eHealth intervention designed to educate HIV-negative and HIV-positive Black and Latinx MSM about PrEP and treatment as prevention (TasP) or Undetectable = Untransmittable (U=U) through the use of social media including Facebook, Twitter, and Instagram [59]. Grounded in the information-motivation-behavioral skills (IMB) and social cognitive theory (SCT) frameworks, For HIMM aims to increase awareness, knowledge, and behavioral intentions towards the use of PrEP and TasP. A culturally tailored interactive website was developed by and for HIV-negative and HIV-positive Black and Latinx MSM along with similarly tailored and IMB/SCT-informed social media messages to encourage these men to repeatedly access and engage with the website over the course of the 6-month intervention. The content and other aspects of the website and social media messages were based heavily on information gathered through focus groups (n = 31 participants; k = 8 focus groups) and cognitive interviews (n = 20 participants) from members of the priority populations. Information on the website in English and in Spanish includes facts about HIV; PrEP and TasP/U=U, and local health care providers who prescribe PrEP or other HIV medications. For HIMM will be tested in an open pilot and a randomized controlled trial (ClinicalTrials.gov NCT03404531). Further information about the website can be found at: www.forhimm.com/ .

Discussion

HIV prevention and care interventions developed and in-progress by MARI early-career scientists have been community-informed, address critical SSDoH disparities, and successfully reach priority populations. Furthermore, these interventions have been focused in geographic areas where HIV disparities are most concentrated and where new HIV prevention and care activities are focused [6, 7]. Early-career scientists, like those supported by MARI, have received training and mentorship that have enabled them to continue as independent investigators committed to advancing the science and public health practice needed to end the HIV epidemic. Continued support and commitment to early-career, historically underrepresented scientists aligns with the shared commitment by federal agencies to invest in innovative ideas, reduce new infections and HIV-related disparities fueled by structural conditions, increase access to care among people living with HIV, and achieve a national coordinated response targeting hardest hit populations in heavily impacted jurisdictions. MARI interventions described in this report are based on primary data collection, which allows for better acceptability with public health partners and affected populations. As such, interventions developed that are found to be effective can greatly strengthen culturally tailored options that are needed for Black and Latinx priority populations.

MARI interventions have addressed and incorporated SSDoH, including internal and external sources of HIV and anti-LGBT stigma, medical mistrust, racial discrimination, anti-immigrant/immigrant rhetoric and policies, mental health and coping, disparate access to education, knowledge, testing and care, social support and capital, adolescent development and cognition, and family support and involvement. Incorporation of these determinants is critical for reaching Black and Latinx priority populations most affected by these SSDoH factors. MARI, through its funding priorities, selection of grantees, and support and mentorship of funded scientists, created opportunities for the development and dissemination of these interventions that has been unparalleled by other existing HIV prevention and care programming. The developed interventions have facilitated and encouraged academic-community partnerships as platforms for implementation science projects to reduce disparities in HIV infection. As an additional example, the COVID-19 pandemic has also highlighted the trickle-down impact of the social and structural determinants on health outcomes among Black and Latinx communities. Opportunities that respond at the intersection of HIV and COVID-19 prevention and treatment are urgently needed, including training the next generation of biobehavioral researchers and supporting capacity building to community-based organizations for pandemics like COVID-19 that hit the disenfranchised the hardest.

Most of the MARI PIs are racial, ethnic and/or sexual minorities historically underrepresented in medicine and public health [4]. More importantly, PIs were competitively selected for their experience with and commitment to working with Black and Latinx priority populations. This experience and commitment have been integral to the development of the culturally appropriate community tailored interventions described above. The importance of cultural competency and representation of racial/ethnic minorities in public health research is well established [60-62].

MARI funding has supported early-career scientists by building on their prior experience and expanding their skill sets through training and mentorship. Therefore, the impact of research initiatives like MARI is far reaching, i.e., long-term career contributions and additional funding for ongoing, innovative HIV prevention, and care research studies. Examples include newly funded studies to address the lack of HIV/HCV co-morbidity interventions in the southern US, dissemination of effective HIV prevention interventions into routine HIV, pediatric and adult care clinical settings in the US, and dissemination of certain strategies developed within Latinx communities to nearby Spanish-speaking countries, if culturally appropriate.

CBOs are critically important to reduce the burden of HIV and ensure long-term success of developed interventions; all MARI interventions in Table 1 included CBO collaborations. Collaborations between MARI PIs and CBOs have been crucial to building greater trust and buy-in from community participants in areas often considered hard-to-reach for scientific research. For example, some of these collaborations included financial support and professional development/capacity building for CBO members. For example, the partnership between Temple University and GALAEI included financial and instructive support by the PI to offset the costs associated with the use of space. In addition, some of these collaborations resulted in training CBO staff on recruitment/engagement strategies, up-to-date data on local HIV epidemiology, and innovative approaches for HIV prevention and treatment. In many cases, we found that the learning was bi-directional, as CBO frontline experiences provided important educational context for the PIs. Furthermore, CBOs which focus on HIV prevention and care are better able to implement interventions that have been developed with community engagement using methods that are culturally aware and sensitive to participant needs. CBOs which directly engage Black and Latinx priority populations often underscore the importance of cultural context for HIV prevention and care interventions when engaging daily with local communities.

HIV disparities impacting Black and Latinx gay, bisexual and other MSM, trans and cisgender women, adolescents and young adults, and other priority populations have been persistent in the US With PrEP, TasP, U=U, and other behavioral and structural interventions, we now have more strategies in our prevention and care toolbox to eliminate these disparities. However, the proper allocation of resources, understanding and incorporation of SSDoH factors, and the effective dissemination and implementation of these tools are vital for these disparities to be addressed and eliminated. MARI has been a cost-effective strategy for developing efficacious and/or effective HIV prevention and care interventions, paving the way for the dissemination of these evidence-based interventions, furthering the science of prevention and treatment in affected communities, and building a culturally competent and diverse scientific and public health workforce. As such, MARI and other similar programmatic and funding strategies remain critical to maximizing the effectiveness of domestic HIV prevention and care efforts in support of ending the HIV epidemic, especially for disproportionately affected communities [6].
