Medical Mistrust and the PrEP Cascade Among Latino Sexual Minority Men

Validation of a Modified Group-Based Medical Mistrust Scale Among Young Latinx Adults in the United States

Medical mistrust is an important barrier to accessing health care among Latinx populations in the United States (US). However, research on the validity and reliability of medical mistrust scales is limited. We examined the validity and reliability of a modified bilingual version of the Group-Based Medical Mistrust scale (mGBMMS) among a sample of Latinx adults. Participants included 308 Latinx adults (ages 18-25), who responded in Spanish (n = 134) or English (n = 174). Following feedback from bilingual/bicultural staff during the English-Spanish translation process, we made three changes to the original GBMMS. Validation testing of our 12-item mGBMMS scale included: split-half and internal consistency reliability; discriminant, convergent, and predictive validity; and both exploratory and confirmatory factor analyses. The mGBMMS had good internal consistency (overall sample: Cronbach's α = 0.79; Spanish: Cronbach's α = 0.73; English: Cronbach's α = 0.83). The mGBMMS showed good convergent (moderately correlated with the experiences of discrimination scale, r = 0.46, p < 0.001) and discriminant (weakly correlated with the acculturation scale, r = 0.11, p = 0.06) validity. Split-half reliability was 0.71 (p < 0.001). Exploratory and confirmatory factor analyses found a two-factor solution. The mGBMMS was associated with satisfaction with care (OR = 0.60, 95%CI: 0.42-0.87), a sign of good predictive validity. Findings suggest that the mGBMMS is a valid and reliable scale to utilize among bilingual (Spanish/English) populations in the US. Further validation studies should be considered among Latinx respondents of different ages, backgrounds, languages, and US regions.

Assessing Structural Racism and Discrimination Along the Pre-exposure Prophylaxis Continuum: A Systematic Review

Structural racism and discrimination (SRD) is deeply embedded across U.S. healthcare institutions, but its impact on health outcomes is challenging to assess. The purpose of this systematic literature review is to understand the impact of SRD on pre-exposure prophylaxis (PrEP) care continuum outcomes across U.S. populations who could benefit from HIV prevention. Guided by PRISMA guidelines, we conducted a systematic review of the published literature up to September 2023 using PubMed and PsycInfo and included peer-reviewed articles meeting inclusion criteria. At least two authors independently screened studies, performed quality assessments, and abstracted data relevant to the topic. Exposure variables included race/ethnicity and any level of SRD (interpersonal, intra- and extra-organizational SRD). Outcomes consisted of any steps of the PrEP care continuum. A total of 66 studies met inclusion criteria and demonstrated the negative impact of SRD on the PrEP care continuum. At the interpersonal level, medical mistrust (i.e., lack of trust in medical organizations and professionals rooted from current or historical practices of discrimination) was negatively associated with almost all the steps across the PrEP care continuum: individuals with medical mistrust were less likely to have PrEP knowledge, adhere to PrEP care, and be retained in care. At the intra-organizational level, PrEP prescription was lower for Black patients due to healthcare provider perception of higher sex-risk behaviors. At the extra-organizational level, factors such as homelessness, low socioeconomic status, and incarceration were associated with decreased PrEP uptake. On the other hand, healthcare provider trust, higher patient education, and access to health insurance were associated with increased PrEP use and retention in care. In addition, analyses using race/ethnicity as an exposure did not consistently show associations with PrEP continuum outcomes. We found that SRD has a negative impact at all steps of the PrEP care continuum. Our results suggest that when assessing the effects of race/ethnicity without the context of SRD, certain relationships and associations are missed. Addressing multi-level barriers related to SRD are needed to reduce HIV transmission and promote health equity.

Factors Influencing Engagement Across the Motivational PrEP Cascade Among Latino SMM: A Mixed-Methods Analysis from the Perspectives of Community Providers and Latino SMM

Latino sexual minority men (SMM) are a highly vulnerable population to HIV, and while pre-exposure prophylaxis (PrEP) has emerged as a promising biomedical tool for HIV prevention among them, its utilization remains disproportionately low in this community despite its potential. Understanding the barriers along the PrEP continuum of care, known as the "PrEP cascade," is crucial for effectively implementing PrEP interventions. Therefore, the objective of our study was twofold: first, to explore the stage of Latino SMM in the PrEP cascade by examining disparities in demographics, social factors, and healthcare aspects; second, to gain insights from healthcare providers who have direct clinical experience with our population regarding the challenges faced by Latino SMM in accessing and adhering to PrEP. Based on the study findings, the majority of participants (n = 74; 49%) were in the contemplation stage, and only one in ten Latino SMM (10.6%) were currently adherent to PrEP. Compared to those who were at least second-generation, first-generation status had a positive association (B = 0.699, SE = 0.208, β = 0.351, p < .001) with engagement along the PrEP Contemplation Ladder. Conversely, having at least one parent who did not have legal residency, relative to those whose parents were both U.S. citizens or held legal residency documentation, was found to have a negative association (B = - 0.689, SE = 0.245, β = 0.245, p = .006) with engagement along the PrEP Contemplation Ladder. Additionally, discussing PrEP with a healthcare provider had a positive association (B = 0.374, SE = 0.179, β = 0.185, p = .038) with engagement along the PrEP Contemplation Ladder. Qualitative results from our study suggest that some Latinos who initially agreed to start using PrEP ended up getting lost in the care pipeline and failed to attend their scheduled appointments. Providers also noted that many patients lacked access to a pharmacy where they felt comfortable obtaining their PrEP prescription, leading them to discontinue use after only a few months. These findings emphasize the importance of considering the unique needs, culture, and background of Latinos, including care delivery and provider attitudes that can facilitate progress through the PrEP cascade.

Peer Influence on Motivation to Use Pre-Exposure Prophylaxis Among Latino Sexual Minority Men in Miami, Florida: A Network Autocorrelation Model

Despite the availability of pre-exposure prophylaxis (PrEP), Latino sexual minority men (LSMM) continue to experience disparities in PrEP uptake and subsequently, HIV vulnerability. Social network norms are an underutilized solution to increase PrEP uptake. We used a peer influence model (network autocorrelation model) to examine the role of social network descriptive norms (i.e., actual behaviors) surrounding PrEP use. A total of 11 sociocentric networks of 13 friends (n = 143 LSMM) were recruited into our study from 2018 to 2019 in South Florida. Most participants were in PrEP pre-contemplation (n = 44), and almost one-third of our sample were using PrEP (n = 38). Three network autocorrelation models were estimated using an empirically informed Bayesian analysis. We found a positive association between participants' Motivational PrEP Cascade (MPC) position and their network members' (friends') cascade position based on three different measures of connection even when accounting for PrEP knowledge: friendship (ρ = 0.22; 95% CIa = 0.01-0.42), emotional closeness (ρ = 0.24; 95% CI = 0.03-0.44), and frequency of interaction (ρ = 0.22; CI = 0.03-0.42). Our findings highlight that an individual's progress in the MPC may be influenced by their network members' progress in the MPC, suggesting that LSMM using PrEP may serve as role models to their peers for PrEP use due to descriptive norms. Our findings further suggest that PrEP interventions for LSMM along the MPC can be implemented at the social network level.

"Honesty, Communication and Trust Are What Bring Peace of Mind": Narratives of HIV Risk Among Hispanic/Latino Men Who Have Sex with Men in the Southern United States

For Hispanic/Latino MSM (HLMSM) in the South, HIV burden remains high, and HIV elimination is a national priority. Between July and September 2016, using a strengths-based approach informed by resilience theory, we conducted qualitative interviews with HIV-negative HLMSM in five southern cities in the United States with elevated HIV prevalence. We analyzed data using a qualitative content analysis approach, assessing for interrater reliability. A brief behavioral survey was also conducted. We enrolled 51 HLMSM (mean age = 33 years, range = 15-63). HLMSM discussed the climate of fear about HIV and homosexuality impeding HIV prevention, including the impact of stigma and taboo. Three main strengths-based strategies emerged for preventing HIV: assessing partner risk, establishing boundaries for sexual interactions, and self-education. Future HIV prevention efforts may benefit from balancing risk-based approaches with those that emphasize resilience, address partner trustworthiness and safety, and focus on providing novel outlets for HIV prevention education.

The Use of a Spanish-Translated PrEP Stigma Scale among the Latino Sample of the UNITE Cohort Study

Pre-Exposure Prophylaxis (PrEP) related stigma is linked to inadequate PrEP uptake, yet there are no validated scales to test this association among Spanish-speaking LSMM. The current study examined if the Spanish-translated PrEP Stigma Scale (PSS) was psychometrically appropriate for implementing in Spanish language dominant Latino/e/x Sexual Minority Men (SMM). Recruitment was conducted using geosocial networking applications, social media sites, and e-mail blasts (N=3,049). First, we utilized Item Response Theory (IRT) modeling to evaluate the reliability of the PSS items and the latent construct across both language groups (nEnglish = 2844 and nSpanish = 205). Subsequently, we applied the PSS scale in a theoretical application by examining its association with key steps in the PrEP uptake cascade (i.e., perceived PrEP candidacy, PrEP willingness, PrEP intentions, and having spoken to provider about PrEP) stratified by language. Results of the IRT analyses provided evidence that the translated version of the PSS was appropriate for use among this sample. Further, among English respondents, PrEP stigma was negatively associated with perceived PrEP candidacy (B=-0.30, p=<.001), PrEP willingness (B=-0.46, p=<.001), and PrEP intentions (B=-0.23, p=.003). PrEP stigma, among Spanish respondents, was not significantly associated with any of the PrEP cascade steps. This study demonstrated that the PSS scale performs adequately for both English and Spanish-speaking Latino SMM. However, researchers and health professionals alike should pay close attention to the nuanced effects in U.S. based English and Spanish language samples as PrEP stigma may impact the PrEP cascade for one language sample and not the other.

Understanding Preferences for Visualized New and Future HIV Prevention Products Among Gay, Bisexual and Other Men Who Have Sex with Men in the Southern United States: A Mixed-Methods Study

Men who have sex with men (MSM) are vulnerable to HIV infection. Although daily oral pre-exposure prophylaxis (PrEP) prevents HIV among MSM, its usage remains low. We conducted virtual in-depth interviews (IDIs) and focus groups (FGs) with Black, Hispanic/Latino, and White MSM consisting of current PrEP users and those aware of but not currently using PrEP. We delved into their preferences regarding six emerging PrEP products: a weekly oral pill, event-driven oral pills, anal douche/enema, anal suppository, long-acting injection, and a skin implant. Our mixed methods analysis involved inductive content analysis of transcripts for thematic identification and calculations of preferences. Among the sample (n = 98), the weekly oral pill emerged as the favored option among both PrEP Users and PrEP Aware IDI participants. Ranking exercises during FGs also corroborated this preference, with the weekly oral pill being most preferred. However, PrEP Users in FGs leaned toward the long-acting injectable. Conversely, the anal suppository and douche/enema were the least preferred products. Overall, participants were open to emerging PrEP products and valued flexibility but expressed concerns about limited protection for products designed solely for receptive sex. Public health practitioners should tailor recommendations based on individuals' current sexual behaviors and long-term vulnerability to infection.

Preference heterogeneity for HIV pre-exposure prophylaxis care among gay, bisexual, and other men who have sex with men in the United States: a large discrete choice experiment

Background

PrEP uptake among Black and Latino gay, bisexual, and other men who have sex with men (GBM) remains low in the United States. The design and implementation of PrEP delivery programs that incorporate the preferences of Black and Latino GBM may overcome barriers to uptake. We aimed to identify preferences for PrEP care among high-priority GBM in the U.S. with a large discrete choice experiment.

Methods

We conducted two discreet choice experiments (DCE) to elicit care preferences for (1) Starting PrEP and (2) Continuing PrEP care among GBM clinically indicated for PrEP. The DCE web-based survey was nested in a longitudinal cohort study of GBM in the U.S., implemented with video and audio directions among 16-49 year-old participants, not using PrEP, and verified to be HIV-negative. All participants were presented with 16 choice sets, with choices determined by BLGBM and PrEP implementation stakeholders. We calculated overall utility scores and relative importance and used latent class analyses (LCA) to identify classes within the Starting and Continuing PrEP DCE. Multivariable analysis was performed to identify factors associated with class membership.

Findings

Among 1514 participants, mean age was 32 years; 46·5% identified as Latino, 21·4% Black, and 25·2 White; 37·5% had an income less than USD $20,000. Two latent classes were identified for Starting PrEP: Class 1 (n=431 [28·5%]) was driven by preference for more traditional in-person care, and Class 2 (n=1083 [71·5%]) preferred flexible care options and on-demand PrEP. In a multivariable model, having a sexual health doctor (adjusted OR 0·7, CI 0·5, 0·9), having a primary care provider (OR 0·7,CI 0·5, 0·9, p= 0·023), and concerns over PrEP side effects (OR 1·1, CI 1·0,1·2, p= 0·003) were all associated with class membership.

Interpretation

The different preferences identified for PrEP care indicate the need for diverse care and formulation choices to improve PrEP uptake and persistence. Addressing these preferences and understanding the factors that shape them can inform the implementation of programs that increase PrEP uptake.

Mpox on Reddit: a Thematic Analysis of Online Posts on Mpox on a Social Media Platform among Key Populations

The 2022-2023 mpox outbreak has disproportionately impacted gay, bisexual, and other men who have sex with men (GBMSM). The US CDC recommended individuals to explore safer sexual practices that minimize the potential risk of exposure and also strongly encouraged for eligible individuals to prioritize vaccination. This study aimed to analyze social media data related to mpox on Reddit since the mpox outbreak and identify themes associated with the impact on social behaviors and social processes among targeted population. Publicly available data were collected from the social media Reddit. We extracted the summarized mpox-related posts since the beginning of May 2022 from popular subreddits that were popular among GBMSM. We thematically analyzed the content to identify the overall themes related to the GBMSM's responses to the outbreak. There is an overall increase in the number of daily mpox-related posts, with three upticks in late May, late July, and early August 2022, which may correspond to the dates that the first mpox case was identified in the USA, the WHO declared a global public health emergency, and the US Department of Health and Human Services declared a public health emergency. Four themes were identified: (1) changes in sexual behaviors and social activities; (2) mpox vaccine attitude, uptake, and hesitancy; (3) perceived and experienced stigma and homophobia, and mental distress; and (4) online information-seeking and mutual aid and support. GBMSM changed their sexual behaviors and social activities to mitigate their exposure to the virus during this outbreak and actively sought and shared information about mpox vaccination in their respective settings, while some were hesitant due to concerns about side effects and potential effectiveness. Perceived and experienced stigma and discrimination on gay- and same sex-identify have impacted GBMSM's mental health. Interventions to promote the mpox vaccine must address the historical medical mistrust and vaccine hesitancy among GBMSM.

Collaborative PrEP Implementation Strategies for Latino Men Who have Sex with Men: A Health Center-Community Consensus Process

Community-based organizations (CBOs) deliver services in culturally-responsive ways, and could effectively partner with health centers to deliver HIV pre-exposure prophylaxis (PrEP) to Latino men who have sex with men (LMSM). However, few such models exist. We conducted a planning study in collaboration with three CBOs serving LMSM to identify optimal PrEP delivery strategies for health centers and CBOs to implement jointly. We established a Community Expert Panel (CEP) of eight client-facing CBO and health center staff. Over 6 months, the panel met monthly to identify collaborative strategies for PrEP delivery, using a modified Delphi method consisting of the following steps: (1) brainstorming strategies; (2) rating strategies on acceptability, appropriateness and feasibility; (3) review of data from qualitative focus group discussions with CBO clients; and (4) final strategy selection. The panel initially identified 25 potential strategies spread across three categories: improving communication between health centers and CBOs; using low-barrier PrEP options (e.g. telemedicine), and developing locally-relevant, culturally-sensitive outreach materials. Focus groups with CBO clients highlighted a desire for flexible options for PrEP-related care and emphasized trust in CBOs. The final package of strategies consisted of: (1) a web-based referral tool; (2) telemedicine appointments; (3) geographically-convenient options for lab specimen collection; (4) tailored print and social media; and (5) regular coaching sessions with CBO staff. Through a community-engaged process, we identified a package of PrEP delivery strategies that CBOs and health centers can implement in partnership, which have the potential to overcome barriers to PrEP for LMSM.

Medical mistrust as a barrier to HIV prevention and care

Medical mistrust is fueled by conspiracy theories and histories of healthcare systems abuse and is a known determinant of health outcomes in minority populations. Plagued by multiple and pervasive conspiracy theories, HIV/AIDS has proven to be particularly hampered by medical mistrust. The current paper systematically reviews the literature on medical mistrust among people at risk for or living with HIV infection. The bulk of evidence from 17 studies supports medical mistrust as a barrier to HIV testing, engagement in prevention and care services, treatment uptake and adherence, and clinical outcomes. While findings mostly indicate that medical mistrust is a barrier to HIV prevention and care, some studies report null results and others suggest that medical mistrust may actually improve some HIV-related outcomes. Additionally, most of the reviewed literature was cross-sectional. Thus longitudinal, theory-driven research is needed to reconcile inconsistent findings and determine long term outcomes of medical mistrust. Interventions may then be developed to reduce the negative consequences associated with medical mistrust.

Pre-exposure Prophylaxis Use and Discontinuation in a Federally Qualified Health Center in a Mexico-US Border City

BACKGROUND

Latino men who have sex with men (MSM) experience disproportionately high rates of HIV diagnoses in the United States. Pre-exposure prophylaxis (PrEP) use is critical to reduce this inequity, but PrEP awareness, access, and use are low among Latino MSM. This study aims to describe patterns of PrEP persistence and discontinuation among predominately Latino MSM accessing PrEP in a federally qualified health center (FQHC) in El Paso, Texas.

METHODS

This retrospective cohort comprised individuals who were eligible for PrEP at a FQHC in El Paso, Texas, between January 30, 2019, and August 15, 2021. We defined hierarchical categories of PrEP use and discontinuation, which was defined as more than 120 days between PrEP visits. We used Kaplan-Meier survival plots to estimate median time to first PrEP discontinuation.

RESULTS

There were 292 patients evaluated for PrEP; 91% were Latino. The majority of PrEP patients (70%, 205/292) experienced any PrEP discontinuation, and the median time to first PrEP discontinuation was 202 days (95% CI: 179-266). The proportion of patients who remained on PrEP at 3 months after initiation was 82% (95% CI: 76%, 87%) and at 6 months after initiation was 55% (95% CI: 46%, 62%).

CONCLUSION

While 3-month PrEP retention was high in this predominately Latino MSM patient population, PrEP discontinuation was common. Interventions that enhance longer-term persistence and support for restarting PrEP are needed to reduce the persistent ethnoracial disparities in HIV incidence.

Everyday Discrimination and HIV Testing Among Partnered Latino/x Sexual Minority Men in the United States: A Stratified Analysis by Birth Location

We examined the association between everyday discrimination and HIV testing patterns-current (≤ 6 months), recent (7-12 months), and delayed (> 12 months or never tested)-among partnered Latino/x sexual minority men (SMM). Multinomial regression analyses revealed that in the full sample (N = 484) experiencing discrimination based on sexual orientation and race/ethnicity attributions concurrently (vs. no discrimination) was associated with higher odds of delayed (vs. current) HIV testing (AOR = 2.6, 95% CI [1.0, 6.7]). Similarly, in the subset of Latino/x SMM born outside the mainland U.S. (n = 209), experiencing concurrent sexual orientation- and race/ethnicity-based discrimination (vs. no discrimination) was associated with higher odds of recent (AOR = 12.4, 95% CI [1.3, 115.7]) and delayed HIV testing (AOR = 7.3, 95% CI [1.6, 33.0]), compared with current testing. Findings suggest that addressing discrimination may improve HIV testing uptake among partnered Latino/x SMM, particularly those born outside the U.S.

Is the USA on track to end the HIV epidemic?

Despite progress in reducing new HIV infections in the USA, publicly available data suggest that new HIV infections continue to occur at an alarming rate. In this Viewpoint, we highlight the regularity with which the existing systems for HIV prevention and treatment delivery in the USA fail and the clearly inequitable effect of the systems' failure among several priority populations of the Ending the HIV Epidemic (EHE) initiative. Existing data cast doubt on whether the current EHE efforts will suffice to achieve its 2030 goal of reducing annual new HIV infections to fewer than 3000. We outline future directions in four priority areas to regain lost ground in pursuit of the 2030 EHE goals: reducing the stigma affecting people living with and most at risk of HIV; broadening the HIV workforce; mitigating harmful social determinants of health; and recommitting and reinvesting in health in the USA more broadly.

Medical Mistrust Among a Racially and Ethnically Diverse Sample of Sexual Minority Men

Purpose: Medical mistrust is a barrier to health care utilization and is associated with suboptimal health outcomes. Research on mistrust among sexual minority men (SMM) is limited and largely focuses on Black SMM and HIV, with few studies assessing mistrust among SMM of other race/ethnicities. The purpose of this study was to examine differences in medical mistrust among SMM by race. Methods: From February 2018 to February 2019, a mixed-methods study examined the health-related beliefs and experiences of young SMM in New York City. The Group-Based Medical Mistrust Scale (GBMMS) was used to measure medical mistrust related to race, and a modified version of the scale assessed mistrust related to one's "sexual/gender minority" status (Group-Based Medical Mistrust Scale-Sexual/Gender Minority [GBMMS-SGM]). With an analytic sample of 183 cisgender SMM, a one-way multivariate analysis of variance was used to examine differences in GBMMS and GBMMS-SGM scores by race/ethnicity [Black, Latinx, White, "Another Racial Group(s)"]. Results: There were significantly different GBMMS scores by race, with participants of color reporting higher levels of race-based medical mistrust than White participants. This finding is supported by effect sizes ranging from moderate to large. Differences in GBMMS-SGM scores by race were borderline; however, the effect size for Black and White participants' GBMMS-SGM scores was moderate, indicating that higher GBMMS-SGM scores among Black participants is meaningful. Conclusion: Multilevel strategies should be used to earn the trust of minoritized populations, such as addressing both historical and ongoing discrimination, moving beyond implicit bias trainings, and strengthening the recruitment and retention of minoritized health care professionals.

Analysis of online user discussions on Reddit associated with the transition of use between HIV PrEP therapy

In 2019, the U.S. Food and Drug Administration (FDA) approved emtricitabine and tenofovir alafenamide (Descovy) as another option for HIV pre-exposure prophylaxis (PrEP) prevention for high-risk adults and adolescents. With the introduction of this new PrEP, millions of current users on emtricitabine and tenofovir disoproxil fumarate (Truvada), another PrEP medication currently used to prevent HIV transmission, have options of whether to continue their current treatment regime or transition to new treatment options. The objective of this study was to conduct a descriptive analysis to characterize user-generated social media conversations on Reddit associated with FDA-approved PrEP prevention treatment options. Key themes identified were associated with perceptions, knowledge, and attitudes associated with the transition of use of different PrEP medications. Data were collected retrospectively and prospectively from the Reddit platform for posts with keywords filtered for HIV, PrEP, and FDA-approved PrEP prevention treatment from October 2020 to December 2020. We chose the Reddit platform based on prior studies that have identified PrEP user conversations and insights on access challenges for specific AIDS communities, such as gays and men who have sex with men (MSM). Reddit posts were then manually annotated using an inductive content coding approach for key themes regarding the transition of use and other emergent themes from user-generated content. Formal coding of text data was conducted with refined codes, and sub-codes created. A total of 3,120 posts were analyzed from Reddit resulting in 315 posts that were coded for PrEP and 105 posts (33.33%) specific to user discussions regarding the transition of PrEP prevention. Overall, users expressed interest in drug switching to Descovy, particularly in the context of poorer adherence or concerns about existing side effects associated with Truvada. Other major themes included discussions about the cost of Descovy, apprehension about side effects in comparison to Truvada, insurance coverage changes, and discussions about the donation of Truvada to other users after transitioning. Among these discussions, topics related to sexual minorities, including MSM, reported concerns when considering a switch in their HIV prevention regime. Understanding the changing public perception associated with the introduction of new HIV prevention is important in the context of market access, patient safety, pharmacovigilance, and health equity, particularly among high-risk populations such as MSM. Results support the use of social media from a digital pharmacovigilance perspective to better understand emerging HIV prevention, treatment, and adherence challenges experienced by patients.

Reasons for not using pre-exposure prophylaxis for HIV and strategies that may facilitate uptake in Ontario and British Columbia among gay, bisexual and other men who have sex with men: a cross-sectional survey

BACKGROUND

Pre-exposure prophylaxis (PrEP) for HIV is underutilized. We aimed to identify barriers to use of PrEP and strategies that may facilitate its uptake.

METHODS

Gay, bisexual and other men who have sex with men, aged 19 years or older and living in Ontario and British Columbia, Canada, completed a cross-sectional survey in 2019-2020. Participants who met Canadian PrEP guideline criteria and were not already using PrEP identified relevant barriers and which strategies would make them more likely to start PrEP. We described the barriers and strategies separately for Ontario and BC.

RESULTS

Of 1527 survey responses, 260 respondents who never used PrEP and met criteria for PrEP were included. In Ontario, the most common barriers were affordability (43%) and concern about adverse effects (42%). In BC, the most common reasons were concern about adverse effects (41%) and not feeling at high enough risk (36%). In Ontario, preferred strategies were short waiting time (63%), the health care provider informing about their HIV risk being higher than perceived (62%), and a written step-by-step guide (60%). In BC, strategies were short waiting time (68%), people speaking publicly about PrEP (68%), and the health care provider counselling about their HIV risk being higher than perceived (64%), adverse effects of PrEP (65%) and how well PrEP works (62%).

INTERPRETATION

Concern about adverse effects and not self-identifying as having high risk for HIV were common barriers, and shorter waiting times may increase PrEP uptake. In Ontario, the findings suggested lack of affordability, whereas in BC, strategies involving health care providers were valued.

Public Health Response to Clusters of Rapid HIV Transmission Among Hispanic or Latino Gay, Bisexual, and Other Men Who Have Sex with Men - Metropolitan Atlanta, Georgia, 2021-2022

During February 2021-June 2022, the Georgia Department of Public Health (GDPH) detected five clusters of rapid HIV transmission concentrated among Hispanic or Latino (Hispanic) gay, bisexual, and other men who have sex with men (MSM) in metropolitan Atlanta. The clusters were detected through routine analysis of HIV-1 nucleotide sequence data obtained through public health surveillance (1,2). Beginning in spring 2021, GDPH partnered with health districts with jurisdiction in four metropolitan Atlanta counties (Cobb, DeKalb, Fulton, and Gwinnett) and CDC to investigate factors contributing to HIV spread, epidemiologic characteristics, and transmission patterns. Activities included review of surveillance and partner services interview data,† medical chart reviews, and qualitative interviews with service providers and Hispanic MSM community members. By June 2022, these clusters included 75 persons, including 56% who identified as Hispanic, 96% who reported male sex at birth, 81% who reported male-to-male sexual contact, and 84% of whom resided in the four metropolitan Atlanta counties. Qualitative interviews identified barriers to accessing HIV prevention and care services, including language barriers, immigration- and deportation-related concerns, and cultural norms regarding sexuality-related stigma. GDPH and the health districts expanded coordination, initiated culturally concordant HIV prevention marketing and educational activities, developed partnerships with organizations serving Hispanic communities to enhance outreach and services, and obtained funding for a bilingual patient navigation program with academic partners to provide staff members to help persons overcome barriers and understand the health care system. HIV molecular cluster detection can identify rapid HIV transmission among sexual networks involving ethnic and sexual minority groups, draw attention to the needs of affected populations, and advance health equity through tailored responses that address those needs.

Healthcare System Distrust and Non-Prescription Antibiotic Use: A Cross-Sectional Survey of Adult Antibiotic Users

Antibiotic resistance is a major public health concern driven by antibiotic overuse. Antibiotic stewardship programs are often limited to clinical settings and do little to address non-prescription antibiotic use in community settings. This study investigates the association between non-prescription antibiotic use and healthcare system distrust in the United States and Mexico. An online survey was deployed in the United States and Mexico with enhanced sampling through in-person recruiting in the border region. Non-prescription antibiotic use was defined as having bought or borrowed non-prescription oral or injectable antibiotics within the last 3 years. The survey included a previously validated 10-item scale to measure healthcare system distrust. Logistic regression was used to model the use of non-prescription antibiotics by the level of healthcare system distrust, adjusted for demographic characteristics and antibiotic knowledge. In total, 568 survey participants were included in the analysis, 48.6% of whom had used non-prescription oral or injectable antibiotics in the last 3 years. In the fully adjusted regression model, the odds of using non-prescription antibiotics were 3.2 (95% CI: 1.8, 6.1) times higher for those in the highest distrust quartile versus the lowest. These findings underscore the importance of community-based antibiotic stewardship and suggest that these programs are particularly critical for communities with high levels of healthcare system distrust.

Overcoming structural barriers to diffusion of HIV pre-exposure prophylaxis

HIV prevention with antiretroviral medication in the form of pre-exposure prophylaxis (PrEP) offers a critical tool to halt the HIV pandemic. Barriers to PrEP access across drug types, formulations, and delivery systems share remarkable commonalities and are likely to be generalizable to future novel PrEP strategies. Appreciation of these barriers allows for planning earlier in the drug-development pathway rather than waiting for the demonstration of efficacy. The purpose of this article is to propose a core set of considerations that should be included in the drug-development process for future PrEP interventions. A literature synthesis of key barriers to PrEP uptake in the United States was conducted to elucidate commonalities across PrEP agents and delivery methods. Based on the published literature, we divided challenges into three main categories of structural barriers: (1) provider and clinic characteristics; (2) cost considerations; and (3) disparities and social constructs, with potential solutions provided for each. Pragmatic strategies for examining and overcoming these barriers before future PrEP regulatory approval are recommended. If these strategies are considered well before the time of commercial availability, the potential for PrEP to interrupt the HIV pandemic will be greatly enhanced.

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.

"These Girls Have a Chance to be the Future Generation of HIV Negative": Experiences of Implementing a PrEP Programme for Adolescent Girls and Young Women in South Africa

Daily oral pre-exposure prophylaxis (PrEP) is highly efficacious for HIV prevention. Adolescent girls and young women (AGYW) have been prioritised for PrEP delivery in South Africa. A combination HIV prevention intervention providing integrated biomedical, behavioural and structural interventions for AGYW aged 15-24 in twelve districts in South Africa characterised by high HIV prevalence, was implemented 2019-2022. We conducted qualitative interviews to explore PrEP implementation experiences with 38 individuals involved in the implementation of the combination HIV prevention programme, including programme managers and project coordinators, health care providers / nurses, social workers, counsellors, peer group trainers and outreach workers. Narratives included various challenges associated with PrEP uptake, adherence and acceptability experienced by implementers. Barriers to PrEP acceptability included AGYW fears of side effects and preference for injectable versus daily oral PrEP; resistance towards PrEP from AGYW, communities and parents due to a lack of accurate information; PrEP stigma linked to associations with antiretrovirals and assumptions of promiscuity; and issues pertaining to parental consent. Additionally, implementers faced logistical challenges related to procurement, stockouts, and supply of PrEP. Findings highlighted the critical role of parental and community acceptability of PrEP for successful implementation. Overall, PrEP was perceived by implementers as a valuable HIV prevention tool. In order to ensure the accessibility of PrEP for AGYW in South Africa, efforts to reduce stigma and foster social support for PrEP use, campaigns to raise awareness, ensure positive framing of PrEP, and build community acceptability of PrEP, are needed.

Intersecting Communities and PrEP Uptake among US-based Latinx Sexual Minority Men

The Latinx community in the USA continues to be disproportionately burdened by the HIV epidemic, especially among Latinx sexual minority men (LSMM). Research indicates that up to two-thirds of new HIV infections occur among men who have sex with men (MSM) within primary partnerships. One promising biomedical approach for HIV prevention includes community scale-up of pre-exposure prophylaxis (PrEP) among LSMM. We examine the relationship between community connectedness (with the Latinx and gay communities) and PrEP uptake among 307 partnered LSMM who reported casual partner sex (i.e., non-monogamous relationships). Within the sample, approximately thirty percent (29.7%) of participants were on PrEP, and 43.3% reported partner approval for PrEP (i.e., my partner is in favor of PrEP generally), while only 7.2% were opposed to PrEP. Insurance status and income levels were significantly associated with PrEP uptake. There was a significant interaction term (gay community connectedness and Latinx group membership), which was positively associated with PrEP uptake (OR = 2.18; p = .007). Findings suggest that there may be structural barriers preventing this population from seeking and initiating PrEP care. Results point to the utility of integrating culturally relevant content related to intersecting identities and their corresponding communities when conceptualizing community-based and culturally informed interventions to improve the PrEP care cascade among LSMM.

PrEP-related stigma and PrEP use among gay, bisexual and other men who have sex with men in Ontario and British Columbia, Canada

Background

We aimed to explore the association between PrEP-related stereotypes and perceived disapproval (hereafter PrEP-related stigma), and PrEP use.

Methods

We used data from a cross-sectional online survey among adult gay, bisexual, other men who have sex with men in Ontario and British Columbia, Canada. Participants were recruited 2019–2020 in-person from sexual health clinics and outreach programs, and online through dating mobile applications and websites. We used logistic regression models to explore the relationship between PrEP-related stigma and: 1-being a ‘never’ versus ‘current’ PrEP user, and 2-being a ‘former’ versus ‘current’ user.

Results

The median age of the sample was 32 (Q1-Q3 = 27–40), most were white born in Canada (48%), 45% had never used PrEP, 16% were former PrEP users and 39% were current PrEP users. Of 1527 individuals who started the survey, 1190 participants answered questions about PrEP-related stigma: 254 (21.3%) were classified as having low level of PrEP-related stigma, 776 (65.2%) intermediate, and 160 (13.5%) high. No significant association was found when never PrEP users and current PrEP users were compared: adjusted OR = 1.44 (95%-CI: 0.8–2.5). High PrEP-related stigma was positively associated with being a former PrEP user compared to being a current PrEP user: adjusted OR = 2.5 (95%-CI: 1.3–4.9).

Conclusion

PrEP-related stigma is associated with not using PrEP, particularly with PrEP discontinuation. Our findings indicate that stigma persists as a barrier to PrEP use.

Relative Effectiveness of Social Media, Dating Apps, and Information Search Sites in Promoting HIV Self-testing: Observational Cohort Study

Background

Social media sites, dating apps, and information search sites have been used to reach individuals at high risk for HIV infection. However, it is not clear which platform is the most efficient in promoting home HIV self-testing, given that the users of various platforms may have different characteristics that impact their readiness for HIV testing.

Objective

This study aimed to compare the relative effectiveness of social media sites, dating apps, and information search sites in promoting HIV self-testing among minority men who have sex with men (MSM) at an increased risk of HIV infection. Test kit order rates were used as a proxy to evaluate promotion effectiveness. In addition, we assessed differences in characteristics between participants who ordered and did not order an HIV test kit.

Methods

Culturally appropriate advertisements were placed on popular sites of three different platforms: social media sites (Facebook, Instagram), dating apps (Grindr, Jack’D), and information search sites (Google, Bing). Advertisements targeted young (18-30 years old) and minority (Black or Latinx) MSM at risk of HIV exposure. Recruitment occurred in 2 waves, with each wave running advertisements on 1 platform of each type over the same period. Participants completed a baseline survey assessing sexual or injection use behavior, substance use including alcohol, psychological readiness to test, attitudes toward HIV testing and treatment, and HIV-related stigma. Participants received an electronic code to order a free home-based HIV self-test kit. Follow-up assessments were conducted to assess HIV self-test kit use and uptake of pre-exposure prophylaxis (PrEP) at 14 and 60 days post enrollment.

Results

In total, 271 participants were enrolled, and 254 were included in the final analysis. Among these 254 participants, 177 (69.7%) ordered a home HIV self-test kit. Most of the self-test kits were ordered by participants enrolled from dating apps. Due to waves with low enrollment, between wave statistical comparisons were not feasible. Within wave comparison revealed that Jack’D showed higher order rates (3.29 kits/day) compared to Instagram (0.34 kits/day) and Bing (0 kits/day). There were no associations among self-test kit ordering and HIV-related stigma, perceptions about HIV testing and treatment, and mistrust of medical organizations.

Conclusions

Our findings show that using popular dating apps might be an efficient way to promote HIV self-testing. Stigma, perceptions about HIV testing and treatment, or mistrust of medical organizations may not affect order rates of HIV test kits promoted on the internet.

Substance Use and Healthcare Utilization Across the Pre-Exposure Prophylaxis (PrEP) Care Cascade among Black and Latino Men Who Have Sex with Men

Background: Despite the documented efficacy of pre-exposure prophylaxis (PrEP) for HIV prevention, large disparities in uptake and adherence exist among Black and Latino/Hispanic men who have sex with men (BLMSM). Limited data exists among BLMSM on the impact of substance use at different stages of the PrEP Care Cascade. We examined the ways substance (alcohol, cannabis, other drug) use is related to PrEP experiences across the PrEP Care Cascade (PrEP aware/no use; PrEP use/discontinuation; PrEP use/adherent).Methods: We utilized data from a national sample of 908 BLMSM (Mage = 25.17, range: 18-29), collected between February and October 2020.Results: We found that heavier alcohol use, more other drug (e.g., cocaine) use, more participant healthcare utilization, and higher number of partners across all measures of substance use were separately associated with a lower likelihood of being aware of PrEP. These same factors were also associated with a higher likelihood of PrEP adherence. Conversely, only cannabis use was associated with discontinuation of PrEP use.Conclusions: While we confirm some earlier findings (i.e., alcohol use is associated with both PrEP discontinuation and PrEP use), we newly identify cannabis as a barrier to the adherence of PrEP. Our findings highlight the need for improved PrEP interventions to increase awareness among BLMSM with substance use who are among the most at-risk for HIV infection.

Using a Structural-Ecological Model to Facilitate Adoption of Preexposure Prophylaxis Among Latinx Sexual Minority Men: A Systematic Literature Review

Research has consistently shown that individual, interpersonal, community and structural factors influence the degree to which individuals' access and utilize health care services, and these factors may play a role in explaining racial and ethnic differences in health care outcomes. Differences in HIV prevalence and treatment between Latinx adults and white adults in the U.S. must be considered in the context of these factors. However, much of the existing research connecting these factors and HIV/AIDS outcomes in Latinxs remains disparate, limited in scope, and has yet not been applied to the use of biomedical HIV preventions. The following systematic literature review examined research related to PrEP in Latinx sexual minority men (SMM) to build a structural-ecological framework of the existing research, while identifying gaps in the literature and areas for future research. We searched two electronic databases using a systematic review protocol, screened 71 unique records, and identified 23 articles analyzing data from Latinx SMM and intended and/or actual PrEP-use in the United States. Based on the present review, disparities in PrEP uptake by Latinx SMM could be explained, in part, by examining how all levels of the structural-ecological framework uniquely contributes to how Latinx SMM engage with HIV prevention measures and come to understand PrEP. It is clear from the existing literature base that some of the most prominent barriers deterring Latinx SMM from seeking PrEP services are the lack of information surrounding PrEP and HIV/gay stigmas. However, higher order structural-level risks can facilitate or reduce access to PrEP. We propose a structural-ecological model to help visualize multi-level domains of unique stressors that limit the implementation of PrEP among Latinxs. At this stage, the available literature provides little guidance beyond suggesting that culturally adapted interventions can be effective in this population. The model developed here provides that needed specificity regarding targeted interventions that will fit the needs of this population.

Refining an Implementation Strategy to Enhance the Reach of HIV-Prevention and Behavioral Health Treatments to Latino Men Who Have Sex with Men

Background

Latino men who have sex with men (LMSM) experience HIV and behavioral health disparities. Yet, evidence-based interventions, such as pre-exposure prophylaxis (PrEP) and behavioral health treatments, have not been equitably scaled up to meet LMSM needs. To address quality of life and the public health importance of HIV prevention, implementation strategies to equitably scale up these interventions to LMSM need to be developed. This study identifies themes for developing culturally grounded implementation strategies to increase uptake of evidence-based HIV prevention and behavioral health treatments among LMSM.

Methods

Participants included 13 LMSM and 12 stakeholders in Miami, an HIV epicenter. Feedback regarding the content, design, and format of an implementation strategy to scale up HIV-prevention and behavioral health services to LMSM were collected via focus groups (N=3) and individual interviews (N=3). Themes were inductively identified across the Health Equity Implementation Framework (HEIF) domains.

Results

Analyses revealed five higher order themes regarding the design, content, and format of the implementation strategy: cultural context, relationships and networks, navigation of health information and systems, resources and models of service delivery, and motivation to engage. Themes were applicable across HEIF domains, meaning that the same theme could have implications for both the development and implementation of the implementation strategy.

Conclusions

Findings highlight the importance of addressing culturally specific factors, leveraging relational networks, facilitating navigation of health systems, tailoring to available resources, and building consumer and implementer motivation in order to refine an implementation strategy for reducing mental health burden and achieving HIV health equity among LMSM.

Diagnosing PrEP Communication Self-Efficacy in a Community-Based Peer Leader Intervention for Black Sexual Minority Men

HIV prevention interventions that leverage endogenous peer leaders to communicate about Pre-Exposure Prophylaxis (PrEP) and other HIV prevention tools in their social networks offer a way to reach greater portions of communities most impacted by HIV like Black/African American gay, bisexual, same gender-loving, and other sexual minority men (BSMM). However, the success of these interventions hinge on the communication self-efficacy of its peer leaders. In this exploratory study, we present a multi-theoretical framework that situates the PrEP communication self-efficacy (PCSE) of a cohort of young BSMM peer leaders (n = 303) in the context of personal, behavioral, social, and structural factors. Using censored regression models, our analysis shows that PCSE is influenced by evaluations of PrEP itself (its relative advantage, complexity, and compatibility), network embeddedness (degree centrality) among other BSMM, social media network exposure to HIV information, and medical mistrust. We conclude with a discussion of the practical implications of our findings for intervention design and implementation.

Dismantling Barriers and Transforming the Future of Pre-Exposure Prophylaxis Uptake in Young Black and Latinx Sexual Minority Men and Transgender Women

Pre-exposure prophylaxis (PrEP) has the potential to transform HIV in young Black and Latinx sexual minority men (SMM) and transgender women (TW). Addressing low PrEP uptake in this population depends on the better understanding of barriers to PrEP use. This article uses an ecological framework to explore barriers to daily oral PrEP in a sample of young Black and Latinx SMM and TW in three geographically prioritized cities in the United States. In-depth interviews were completed with 33 young Black and Latinx SMM and TW (22 at risk for and 11 recently diagnosed with HIV), aged 17-24, participating in a randomized trial aimed at increasing PrEP and antiretroviral therapy (ART) uptake and adherence. Interviews were recorded and transcribed, and then analyzed using inductive and deductive coding. Coded transcripts were organized into individual, interpersonal, community, and structural categories, by PrEP use and HIV status. Among participants, nine reported having been prescribed PrEP, with five actively or recently taking PrEP, whereas only one participant diagnosed with HIV had been prescribed PrEP. Major themes related to barriers emerged across the individual, family, community, and structural level. Limited barriers related to partners, instead partners with HIV encouraged PrEP use. Participants commonly reported low perceived HIV risk, fear of disclosure, barriers relating to insurance/cost, and medication use as reasons for nonuse of PrEP. For youth to remain on a healthy life course, HIV preventative measures will need to be adopted early in adolescence for those at risk of HIV acquisition. Interventions need to simultaneously address multilevel barriers that contribute to nonuse in adolescents. Clinical trials registry site and number: ClinicalTrials.gov Identifier: NCT03194477.

Partners' Consensus About Joint Effort and COVID-19 Prevention Among Sexual Minority Men

The current study examined the relevance of relationship functioning to partners' agreement or consensus about joint effort surrounding COVID-19 prevention. Interdependence theory has been widely used to understand how relationship partners influence health behavior, including how sexual minority male (SMM) couples regulate HIV risk. Couples with better relationship functioning tend to be more successful at negotiating joint (shared) goals and subsequently accomplishing them. The study recruited 134 cis-male, SARS-CoV-2 negative adults in relationships with cis-male partners from phone-based social networking applications. Participants completed an online survey assessing relationship functioning (Perceived Relationship Components Questionnaire), COVID-19 prevention behaviors, and risk perceptions. Partners' consensus around joint COVID-19 prevention effort was assessed using an adapted version of the Preferences for Sexual Health Outcomes scale. Path analyses indicated that consensus for joint prevention effort predicted social distancing (B = 0.23; p = .001) and the number of other COVID-19 prevention behaviors engaged in (B = 0.17; p = .003) above and beyond perceived risk and relationship functioning. Relationship satisfaction predicted higher levels of consensus for joint COVID-19 prevention effort (B = 0.40; p = .029). Findings suggest that the theoretical foundations of successful HIV prevention interventions that utilize joint goal formation may generalize to the prediction of COVID-19 prevention behavior and may be leveraged to mitigate the risk of SARS-CoV-2 infection among SMM in relationships. Interventions that overlook the potential for dyadic regulation of health behavior may miss opportunities to capitalize on shared coping resources and fail to address relational barriers to prevention.

Toward Greater Pre-exposure Prophylaxis Equity: Increasing Provision and Uptake for Black and Hispanic/Latino Individuals in the U.S

Pre-exposure prophylaxis (PrEP) is highly effective at preventing HIV acquisition and is a critical tool in the Ending the HIV Epidemic in the U.S. initiative. However, major racial and ethnic disparities across the pre-exposure prophylaxis continuum, secondary to structural inequities and systemic racism, threaten progress. Many barriers, operating at the individual, network, healthcare, and structural levels, impede PrEP access and uptake within Black and Hispanic/Latino communities. This review provides an overview of those barriers and the innovative and collaborative solutions that health departments, healthcare organizations, and community partners have implemented to increase PrEP provision and uptake among disproportionately affected communities. Promising strategies at the individual and network levels focus on increasing patient support throughout the PrEP continuum, positioning and training community members to expand knowledge of and interest in PrEP, and leveraging mobile technologies to support PrEP uptake. Healthcare-level solutions include expanding the venues and types of healthcare professionals that can provide PrEP, and structural- and policy-level options focus on financial assistance programs and health insurance expansion. Key research gaps include demonstrating that pilot studies and interventions remain effective at scale and across varied contexts. Although the last 2 decades have provided effective tools to end the HIV epidemic, realizing this vision for the U.S. will require addressing persistent and pervasive HIV-related disparities in Black and Hispanic/Latino communities. Federal, state, and local partners should expand efforts to address longstanding health and structural inequities and partner with disproportionately affected communities to rapidly expand PrEP scale-up.

"PrEP's just to secure you like insurance": a qualitative study on HIV pre-exposure prophylaxis (PrEP) adherence and retention among black cisgender women in Mississippi

BACKGROUND

Pre-exposure prophylaxis (PrEP) has the potential to reduce transmission of HIV among Black cisgender women in the Southern United States (U.S.); however, national data suggests that PrEP initiation is lowest in the South and among Black women compared to other U.S. regions and white women. This study applied intersectionality and PrEP multilevel resilience frameworks to assess how socio-structural and clinical contexts shaped PrEP persistence among Black cisgender women in Mississippi.

METHODS

Semi-structured interviews were conducted with eight Black cisgender women in Jackson, Mississippi. This sample was purposively recruited to include PrEP-initiated Black cisgender women.

RESULTS

Six themes identified that shaped PrEP care among Black cisgender women: (1) internal assets, (2) sole responsibility to HIV prevention, (3) added protection in HIV serodifferent relationships, (4) financial issues, (5) trust and distrust in the medical system, and (6) side effects. Black cisgender women reported that PrEP persistence increased control over their sexual health, reduced anxiety about HIV, and promoted self-care. Black cisgender women also indicated that medication assistance programs increased PrEP affordability resulting in continued persistence.

CONCLUSIONS

In addition to preventing HIV, PrEP may yield secondary positive impacts on the health and relationships of Black cisgender women. However, very few Black cisgender women in the South are using PrEP given intersectional barriers and thus necessitates adaptive strategies to support PrEP initiation and persistence. Efforts aimed at increasing the coverage of PrEP among Black cisgender women should consider implementation strategies responsive to lived realities of Black women.

Linking racism and homonegativity to healthcare system distrust among young men of color who have sex with men: Evidence from the Healthy Young Men's (HYM) study

BACKGROUND

Experiences with racism predict healthcare system distrust among people of color, but Black and Latino young men who have sex with men (YMSM) also experience overlapping forms of stigma associated with their sexual identities and behaviors (i.e., homonegativity and internalized homonegativity). These forms of minority stress may drive healthcare system distrust among Black and Latino YMSM but have received far less attention.

OBJECTIVES

To examine the associations of racism, homonegativity, and internalized homonegativity with healthcare system distrust among a community sample of Black and Latino YMSM.

METHODS

Data came from waves 2-4 (years 2017-2018) of the Healthy Young Men's study, a longitudinal cohort study of Black and Latino YMSM living in Los Angeles County. Data across waves (n = 424, nobs = 1272) were combined and analyzed using a fixed effects approach and adjusting for repeated measures across participants. A series of regression models that added sets of covariates (demographics, syndemic indicators, and health-related factors) were tested to examine associations of racism, homonegativity, and internalized homonegativity with healthcare system distrust.

RESULTS

Adjusting for demographics and syndemic indicators, racism, but not homonegativity or internalized homonegativity, was associated with healthcare system distrust. Adjustment for health-related factors had little impact on results.

CONCLUSIONS

Among Black and Latino YMSM, greater exposure to racism is associated with greater healthcare system distrust. Efforts to strengthen healthcare system trust should explicitly target the institutional policies that disproportionately harm people of color.

A Rapid Review of Disparities in HIV Prevention and Care Outcomes Among Hispanic/Latino Men Who Have Sex With Men in the United States

In the United States, Hispanic/Latino men who have sex with men (HLMSM) are disproportionally affected by HIV. We conducted a rapid review of national surveillance data to examine disparities in HIV prevention and care outcomes among HLMSM. Thirteen reports provided relevant data from 2011 to 2018. Compared to White MSM, a higher percentage of HIV-negative HLMSM reported not taking PrEP and engaging in condomless sex; a lower percentage of HIV-negative HLMSM at risk for HIV reported PrEP awareness and use; and a lower percentage of HIV-positive HLMSM were aware of their status, linked to HIV care, and virally suppressed. Viral suppression rates in HLMSM were better among Ryan White clients than the national rates, suggesting that access to comprehensive care/services reduces disparities. Findings also call for identifying individual, social, and structural factors contributing to condomless sex without PrEP use and HIV status unawareness and identifying best approaches for scaling up comprehensive care/services.

Referral Linkage to Preexposure Prophylaxis Care and Persistence on Preexposure Prophylaxis in an Integrated Health Care System

BACKGROUND

Successful linkage to preexposure prophylaxis (PrEP) and retention in care are important for HIV prevention. We examined gaps in PrEP care following referral and factors associated with PrEP linkage and persistence in an integrated health care system in the United States.

METHODS

We identified individuals referred for PrEP from 2014 to 2017 at the Kaiser Permanente Southern California using electronic health records and assessed linkage to care, PrEP prescription orders and fills, and PrEP persistence (medication possession ratio ≥80%) in the year after the first fill. We evaluated demographic and clinical factors potentially associated with PrEP linkage and persistence using a series of multivariable modified Poisson regression models.

RESULTS

Of 2995 referred individuals, 74.9% were linked to PrEP care. Nearly all those linked to care were prescribed PrEP and filled a prescription, but only 47.4% of those who filled a prescription were persistent on PrEP. Individuals aged <25 years (vs ≥25 years), female subjects (vs males), and individuals with high-deductible insurance (vs no high deductible) were less likely to be linked to care. Individuals aged <25 years and Hispanics (vs non-Hispanic whites) were less likely to be persistent. Those with alcohol use disorder were more likely to be linked to PrEP care but less likely to be persistent. New HIV diagnoses occurred in 38 individuals, and only 1 had PrEP in possession at diagnosis.

CONCLUSIONS

We observed PrEP care gaps and disparities among individuals referred for PrEP. Patient-centered interventions are needed in primary care to address barriers to successful PrEP linkage and persistence.

Pilot randomised controlled trial of a patient navigation intervention to enhance engagement in the PrEP continuum among young Latino MSM: a protocol paper

INTRODUCTION

Men who have sex with men (MSM) are one of the most at-risk group for contracting HIV in the USA. However, the HIV epidemic impacts some groups of MSM disproportionately. Latino MSM comprise 25.1% of new HIV infections among MSM between the ages of 13 and 29 years. The daily medication tenofovir/emtricitabine was approved by the Food and Drug Administration for pre-exposure prophylaxis (PrEP) in 2012 and has demonstrated strong efficacy in reducing HIV acquisition.

METHODS AND ANALYSIS

Through extensive formative research, this study uses a pilot randomised controlled trial design and will examine the feasibility and acceptability of a patient navigation intervention designed to address multiple barriers to improve engagement in the PrEP continuum among 60 Latino MSM between the ages of 18 and 29 years. The patient navigation intervention will be compared with usual care plus written information to evaluate the feasibility and acceptability of the intervention and study methods and the intervention's potential in improving PrEP continuum behaviours. The results will be reviewed for preparation for a future full-scale efficacy trial.

ETHICS AND DISSEMINATION

This study was approved by the institutional review board at San Diego State University and is registered at ClinicalTrials.gov. The intervention development process, plan and the results of this study will be shared through peer-reviewed journal publications, conference presentations and healthcare system and community presentations.

REGISTRATION DETAILS

Registered under the National Institutes of Health's ClinicalTrials.gov (NCT04048382) on 7 August 2019 and approved by the San Diego State University (HS-2017-0187) institutional review board. This study began on 5 August 2019 and is estimated to continue through 31 March 2021. The clinical trial is in the pre-results stage.

Patient-Led Decision-Making for HIV Preexposure Prophylaxis

PURPOSE OF REVIEW

Shared decision-making is a process that involves bidirectional exchange of information between patients and providers to support patients in making individualized, evidence-based decisions about their healthcare. We review the evidence on patient-led decision-making, a form of shared decision-making that maximizes patient autonomy, as a framework for decisions about HIV preexposure prophylaxis (PrEP). We also assess the likelihood that patient-led decision-making occurs for PrEP and describe interventions to facilitate this process.

RECENT FINDINGS

Patient-led decision-making is likely to be uncommon for PrEP, in part because healthcare providers lack knowledge and training about PrEP. Few evidence-based interventions exist to facilitate patient-led decision-making for PrEP. There is a need for rigorously developed interventions to increase knowledge of PrEP among patients and healthcare providers and support patient-led decision-making for PrEP, which will be increasingly important as the range of available PrEP modalities expands.

COVID-19 Related Medical Mistrust, Health Impacts, and Potential Vaccine Hesitancy Among Black Americans Living With HIV

BACKGROUND

Medical mistrust, a result of systemic racism, is prevalent among Black Americans and may play a role in COVID-19 inequities. In a convenience sample of HIV-positive Black Americans, we examined associations of COVID-19-related medical mistrust with COVID-19 vaccine and COVID-19 treatment hesitancy and negative impacts of COVID-19 on antiretroviral therapy (ART) adherence.

METHODS

Participants were 101 HIV-positive Black Americans (age: M = 50.3 years; SD = 11.5; 86% cisgender men; 77% sexual minority) enrolled in a randomized controlled trial of a community-based ART adherence intervention in Los Angeles County, CA. From May to July 2020, participants completed telephone interviews on negative COVID-19 impacts, general COVID-19 mistrust (eg, about the government withholding information), COVID-19 vaccine and treatment hesitancy, and trust in COVID-19 information sources. Adherence was monitored electronically with the Medication Event Monitoring System.

RESULTS

Nearly all participants (97%) endorsed at least one general COVID-19 mistrust belief, and more than half endorsed at least one COVID-19 vaccine or treatment hesitancy belief. Social service and health care providers were the most trusted sources. Greater COVID-19 mistrust was related to greater vaccine and treatment hesitancy [b (SE) = 0.85 (0.14), P < 0.0001 and b (SE) = 0.88 (0.14), P < 0.0001, respectively]. Participants experiencing more negative COVID-19 impacts showed lower ART adherence, assessed among a subset of 49 participants [b (SE) = -5.19 (2.08), P = 0.02].

DISCUSSION

To prevent widening health inequities, health care providers should engage with communities to tailor strategies to overcome mistrust and deliver evidence-based information, to encourage COVID-19 vaccine and treatment uptake.
