Abstract B041: Community-based prostate cancer screening for Black men

Abstract PURPOSE: The 5-year relative survival rate for men with prostate cancer (PC) is greater than 99% when diagnosed at an early stage. The prognosis is much worse for men diagnosed with advanced disease as there is no cure for metastatic PC. With the establishment of prostate- specific antigen (PSA) blood testing as an effective tool for early screening for PC, the prevention of morbidity and mortality from this disease proves possible. However, Black men are more likely to develop aggressive PC and die, yet less likely to be screened despite population-specific guidelines recommending shared decision-making for high-risk groups to begin at age 40. For these reasons, increasing the rate and reach of PSA screening within the community is an innovative approach to raise awareness and reduce mortality from PC for Black men. METHODS: Morehouse School of Medicine’s (MSM) Prostate Cancer Precision Prevention Program (PCP3) leverages community partnerships to provide point-of-care PSA testing at no cost to Black men in the greater Atlanta area and rural Georgia. Community-based screening events were initiated in June 2023 and have been conducted in collaboration churches, municipalities, and non-profit organizations. Participants were recruited at these events and consented to provide one tube of blood drawn by MSM phlebotomists and registered nurses for quantification of PSA levels. Results were processed through Morehouse Healthcare and participants were contacted with individual results and provided with options for follow-up. RESULTS: To date, PCP3 has conducted more than three dozen community-based screening events. Over 1000 Black men have received PSA testing with variable results. CONCLUSION: PCP3 has provided awareness and PSA testing to over 1000 Black men in Atlanta and rural Georgia at higher risk for aggressive and lethal PC. PCP3 aims to assess whether community- based screening reduces mortality from PC for Black men in Georgia over the next few years. Citation Format: Pam Cooper, Kitty Carter-Wicker, Eddie R.

Ending the HIV epidemic PrEP equity recommendations from a rapid ethnographic assessment of multilevel PrEP use determinants among young Black gay and bisexual men in Atlanta, GA.

Efforts to mitigate HIV transmission among gay and bisexual men have not been sufficient to level persistent racial inequities which now extend to the use of daily oral pre-exposure prophylaxis (PrEP) for HIV prevention. Community-involved ethnographic research is crucial to galvanizing collaboration between patients, researchers, and policymakers to identify the social determinants of emerging PrEP inequities. In partnership with community key informants, we conducted a Rapid Ethnographic Assessment (REA) of multilevel PrEP use determinants among young Black gay and bisexual (YBGBM) men in the metropolitan Atlanta area to inform the development and coordination of local HIV programs. In the assessment, we drew upon the perspectives of local clinicians, community-based organization leaders, health educators, and PrEP clients to identify barriers and facilitators to PrEP use among YBGBM through interviews (N = 23). Data were collected from September 2020 -to January 2021 and were analyzed through a staged deductive-inductive thematic analysis. The themes were later summarized and presented to community stakeholder participants to facilitate member-checking. Our analyses revealed structural, cultural, relationship, and developmental factors which shaped PrEP use. The most prominent being "ease of access to PrEP" (structural level), "provider support" (interpersonal), and "life-stage traits" (individual). Our results also contribute novel information concerning the axes of intersectional stigma (spatial, racial, sexual identity, and HIV) among YBGBM in Atlanta and its divergent effects on PrEP use. Increased PrEP use among YBGBM, particularly among those living in the south, is essential to ending the domestic HIV epidemic. Altogether, our results emphasize the need for PrEP program modifications, which increase flexibility in methods and modes of access and are culturally adapted to the needs of YBGBM. There is also a need for resources that holistically focus on mental health, trauma, and racism as critical components of support.

Examining HIV organizational structures and their influence on engagement with young Black gay, bisexual, and other men who have sex with men in Atlanta, Georgia

Young Black gay, bisexual, and other men who have sex with men (YB-GBMSM) are disproportionately impacted by HIV. Structural influences on these disparities, including characteristics of the various organizations that serve YB-GBMSM living with HIV, remain understudied. We drew on Weick’s model of organizing to conduct and analyze qualitative interviews with 28 HIV service providers representing healthcare and community-based organizations in Atlanta, Georgia. Enactment of HIV service provision was described as following simplified and standardized responses-defined as “rules”, and/or more dynamic exchanges to formulate responses -otherwise known as “communication behavior cycles” (CBCs). Rules, including patient quotas and limited hours of operation, were viewed as rigid, out-of-touch, and inhibiting engagement with YB-GBMSM. CBCs, such as patient feedback loops and rejection of traditional hierarchies, fostered creative insights to combating the epidemic and increased levels of cultural awareness and community buy-in. Organizations should strive to enact CBCs, to foster culturally congruent approaches to service delivery for YB-GBMSM.

Racial differences in the association of undetectable HIV viral load and transportation to an HIV provider among men who have sex with men in Atlanta, Georgia: a health equity perspective

ABSTRACT There are inequities in HIV outcomes among Black gay, bisexual, and other sexual minority men who have sex with men (GBMSM) compared to GBMSM overall, including access to transportation to HIV care. It is unclear if the relationship between transportation and clinical outcomes extends to viral load. We assessed the relationship between transportation dependence to an HIV provider and undetectable viral load among Black and White GBMSM in Atlanta. We collected transportation and viral load information from GBMSM with HIV from 2016–2017 (n = 345). More Black than White GBMSM had a detectable viral load (25% vs. 15%) and took dependent (e.g. public) transportation (37% vs. 18%). Independent (e.g. car) transportation was associated with undetectable viral load for White GBMSM (cOR 3.61, 95% CI 1.45, 8.97) but was attenuated by income (aOR. 2.29, 95% CI 0.78, 6.71), and not associated for Black GBMSM (cOR 1.18, 95% CI 0.58, 2.24). One possible explanation for no association for Black GBMSM is that there are more competing barriers to HIV care for Black GBMSM than White GBMSM. Further investigation is needed to confirm whether 1) transportation is unimportant for Black GBMSM or 2) transportation interacts with additional factors not considered in this analysis.

Cost-Effectiveness of Interventions to Improve HIV Pre-exposure Prophylaxis Initiation, Adherence, and Persistence Among Men Who Have Sex With Men.

To help achieve Ending the HIV Epidemic (EHE) goals of reducing new HIV incidence, pre-exposure prophylaxis (PrEP) use and engagement must increase despite multidimensional barriers to scale-up and limitations in funding. We investigated the cost-effectiveness of interventions spanning the PrEP continuum of care. Men who have sex with men in Atlanta, GA, a focal jurisdiction for the EHE plan. Using a network-based HIV transmission model, we simulated lifetime costs, quality-adjusted life years (QALYs), and infections averted for 8 intervention strategies using a health sector perspective. Strategies included a status quo (no interventions), 3 distinct interventions (targeting PrEP initiation, adherence, or persistence), and all possible intervention combinations. Cost-effectiveness was evaluated incrementally using a $100,000/QALY gained threshold. We performed sensitivity analyses on PrEP costs, intervention costs, and intervention coverage. Strategies averted 0.2%-4.2% new infections and gained 0.0045%-0.24% QALYs compared with the status quo. Initiation strategies achieved 20%-23% PrEP coverage (up from 15% with no interventions) and moderate clinical benefits at a high cost, while adherence strategies were relatively low cost and low benefit. Under our assumptions, the adherence and initiation combination strategy was cost-effective ($86,927/QALY gained). Sensitivity analyses showed no strategies were cost-effective when intervention costs increased by 60% and the strategy combining all 3 interventions was cost-effective when PrEP costs decreased to $1000/month. PrEP initiation interventions achieved moderate public health gains and could be cost-effective. However, substantial financial resources would be needed to improve the PrEP care continuum toward meeting EHE goals.

Integrating and Disseminating Pre-Exposure Prophylaxis (PrEP) Screening and Dispensing for Black Men Who Have Sex With Men in Atlanta, Georgia: Protocol for Community Pharmacies.

BackgroundBlack men who have sex with men (BMSM) suffer from alarmingly high rates of HIV in the United States. Pre-exposure prophylaxis (PrEP) can reduce the risk of HIV infection by 99% among men who have sex with men, yet profound racial disparities in the uptake of PrEP persist. Low PrEP uptake in BMSM is driven by poor access to PrEP, including inconvenient locations of PrEP-prescribing physicians, distrust of physicians, and stigma, which limit communication about PrEP and its side effects. Previous work indicates that offering HIV prevention services in pharmacies located in low-income, underserved neighborhoods is feasible and can reduce stigma because pharmacies offer a host of less stigmatized health services (eg, vaccinations). We present a protocol for a pharmacy PrEP model that seeks to address challenges and barriers to pharmacy-based PrEP specifically for BMSM.ObjectiveWe aim to develop a sustainable pharmacy PrEP delivery model for BMSM that can be implemented to increase PrEP access in low-income, underserved neighborhoods.MethodsThis study design is a pilot intervention to test a pharmacy PrEP delivery model among pharmacy staff and BMSM. We will examine the PrEP delivery model’s feasibility, acceptability, and safety and gather early evidence of its impact and cost with respect to PrEP uptake. A mixed-methods approach will be performed, including three study phases: (1) a completed formative phase with qualitative interviews from key stakeholders; (2) a completed transitional pilot phase to assess customer eligibility and willingness to receive PrEP in pharmacies during COVID-19; and (3) a planned pilot intervention phase which will test the delivery model in 2 Atlanta pharmacies in low-income, underserved neighborhoods.ResultsData from the formative phase showed strong support of pharmacy-based PrEP delivery among BMSM, pharmacists, and pharmacy staff. Important factors were identified to facilitate the implementation of PrEP screening and dissemination in pharmacies. During the transitional pilot phase, we identified 81 individuals who would have been eligible for the pilot phase.ConclusionsPharmacies have proven to be a feasible source for offering PrEP for White men who have sex with men but have failed to reach the most at-risk, vulnerable population (ie, BMSM). Increasing PrEP access and uptake will reduce HIV incidence and racial inequities in HIV. Translational studies are required to build further evidence and scale pharmacy-based PrEP services specifically for populations that are disconnected from HIV prevention resources.International Registered Report Identifier (IRRID)DERR1-10.2196/35590

Seroadaptive Strategy Patterns of Young Black Gay, Bisexual, and Other Men Who Have Sex With Men in Atlanta, Georgia.

Young Black gay, bisexual, and other men who have sex with men (YBMSM) are disproportionally affected by HIV. Seroadaptive strategies-modification of sexual behavior based on an individual's perceived serostatus, the perceived status of the partner, and/or HIV transmission risk by the type of sex act-are often used to reduce the risk of HIV transmission or acquisition. We used demographic, behavioral, and clinical data from Ele[MEN]t, a prospective cohort study of YBMSM aged 18-29 years in Atlanta, GA, conducted during 2015-2019. The prevalence of seroadaptive strategies at baseline was reported, and latent class analysis was used to identify the latent classes of strategies for both YBMSM known and not known to be living with HIV. Latent classes were compared by key behavioral and clinical characteristics to validate our findings. In a 4-class model, the most common latent class of YBMSM not known to be living with HIV (32.4%) was characterized by all individuals reporting only having sex with men not perceived to be living with HIV. The most common latent class of YBMSM known to be living with HIV (48.2%) was characterized by a combination of serosorting strategies, including using condoms for anal sex with partners not known to be living with HIV and avoiding sex with men not known to be living with HIV. YBMSM use various patterns of strategies to reduce their HIV transmission or acquisition risk. Our study highlights the need for targeted HIV prevention recommendations based on individual behaviors.

Condomless receptive anal intercourse is associated with markers of mucosal inflammation in a cohort of men who have sex with men in Atlanta, Georgia.

IntroductionWe previously showed that the rectal mucosal immune environment among men who have sex with men (MSM) engaging in condomless receptive anal intercourse (CRAI) is immunologically distinct from that of men who do not engage in anal intercourse (AI). Here, we further examined these differences with quantitative immunohistochemistry to better understand the geographic distribution of immune markers of interest.MethodsWe enrolled a cohort of MSM engaging in CRAI (n = 41) and men who do not engage in AI (n = 21) between October 2013 and April 2015. Participants were healthy, HIV‐negative men aged 18–45 from the metro Atlanta area. We performed rectal mucosal sampling via rigid sigmoidoscopy during two study visits separated by a median of nine weeks and timed with sexual activity for MSM engaging in CRAI. We used standardized, automated immunohistochemistry and quantitative image analysis to investigate the rectal mucosal distribution of neutrophils (MPO), IL‐17‐producing cells (IL‐17) and Tregs (FOXP3) in the lamina propria, and cellular proliferation (Ki67) and adherens junction protein (E‐cadherin) in the epithelium. We examined associations between biomarker expression and the rectal mucosal microbiota composition by 16s rRNA sequencing.ResultsRelative to the colonic crypt base, IL‐17, FOXP3, and MPO expression increased towards the rectal lumen, while Ki67 decreased and E‐cadherin was more uniformly distributed. Throughout the rectal mucosa distribution examined, MSM engaging in CRAI had higher mean lamina propria MPO expression (p = 0.04) and epithelial Ki67 (p = 0.04) compared to controls. There were no significant differences in IL‐17, FOXP3 or E‐cadherin expression. We found no significant associations of the five biomarkers with the global rectal microbiota composition or the individual taxa examined.ConclusionsUnderstanding the mucosal distribution of inflammatory mediators can enhance our knowledge of the earliest events in HIV transmission. Neutrophil enrichment and crypt epithelial cell proliferation likely represent sub‐clinical inflammation in response to CRAI in the rectal mucosa of MSM, which could increase the risk for HIV acquisition. However, the contributory role of the microbiota in mucosal inflammation among MSM remains unclear. HIV prevention may be enhanced by interventions that reduce inflammation or capitalize on the presence of specific inflammatory mechanisms during HIV exposure.

Sex-Positivity, Medical Mistrust, and PrEP Conspiracy Beliefs Among HIV-Negative Cisgender Black Sexual Minority Men in Atlanta, Georgia.

Because the public health response to the disproportionate HIV burden faced by Black sexual minority men (BSMMM) has focused on sexual risk reduction and disease prevention, other vital components of sexual health (e.g., intimacy, pleasure, benefits of sex) have been often overlooked. Sex-positive describes a more open, holistic approach toward sex and sexuality that prioritizes these other components, though such an approach is rarely applied to BSMM's sexual health. For sex-positive BSMM, risk/preventive discourse may foster or exacerbate medical mistrust as a reaction to the dissonance between how these men view sexual health and how the medical establishment views it, which may discourage sexual healthcare-seeking. We assessed sex-positivity and its association with medical mistrust and PrEP conspiracy beliefs among 206 HIV-negative cisgender BSMM in Atlanta, Georgia. We performed exploratory factor analytic procedures on responses to a sex-positivity scale, followed by multivariable linear regressions to determine sex-positivity's associations with medical mistrust and PrEP conspiracy beliefs. We extracted two sex-positivity factors: sexual freedom (α = 0.90), reflecting openness toward casual sex and rejection of sexual mores, and essence of sex (α = 0.77), reflecting the intimate, relational, and pleasurable qualities of sex. Sexual freedom was independently associated with perceived provider deception (β = 0.19, CI = 0.04, 0.34). Essence of sex was independently associated with PrEP conspiracy beliefs (β = 0.16, CI = 0.02, 0.31) and marginally associated with perceived provider deception (β = 0.14, CI = - 0.00, 0.29). Healthcare providers and public health practitioners may cultivate greater trust with BSMM by incorporating a sex-positive approach into patient/participant interactions, clinical decision-making, and interventions. Improving access to sexual pleasure acknowledges BSMM's right to optimal, holistic sexual health.

Disparities in Care Outcomes in Atlanta Between Black and White Men Who Have Sex With Men Living With HIV: Protocol for a Prospective Cohort Study (Engage[men]t)

BackgroundThe US HIV epidemic is driven by infections in men who have sex with men and characterized by profound disparities in HIV prevalence and outcomes for Black Americans. Black men who have sex with men living with HIV are reported to have worse care outcomes than other men who have sex with men, but the reasons for these health inequities are not clear. We planned a prospective observational cohort study to help understand the reasons for worse HIV care outcomes for Black versus White men who have sex with men in Atlanta.ObjectiveThe aim of this study is to identify individual, dyadic, network, neighborhood, and structural factors that explain disparities in HIV viral suppression between Black and White men who have sex with men living with HIV in Atlanta.MethodsBlack and White men who have sex with men living with HIV were enrolled in a prospective cohort study with in-person visits and viral suppression assessments at baseline, 12 months, and 24 months; additional surveys of care and risk behaviors at 3, 6, and 18 months; analysis of care received outside the study through public health reporting; and qualitative interviews for participants who experienced sentinel health events (eg, loss of viral suppression) during the study. The study is based on the Bronfenbrenner socioecological theoretical model.ResultsMen who have sex with men (n=400) were enrolled between June 2016 and June 2017 in Atlanta. Follow-up was completed in June 2019; final study retention was 80% at 24 months.ConclusionsHealth disparities for Black men who have sex with men are hypothesized to be driven by structural racism and barriers to care. Observational studies are important to document and quantify the specific factors within the socioecological framework that account for disparities in viral suppression. In the meantime, it is also critical to push for steps to improve access to care, including Medicaid expansion in Southern states, such as Georgia, which have not yet moved to expand Medicaid.International Registered Report Identifier (IRRID)DERR1-10.2196/21985

Exploring influences on methamphetamine use among Black gay, bisexual and other men who have sex with men in Atlanta: A focus group study

BackgroundMethamphetamine use is a contributor to HIV risk and poor health outcomes among gay, bisexual and other men who have sex with men (GBMSM). There is a paucity of research examining methamphetamine use and its social context specifically among Black GBMSM. We therefore sought to: (1) describe trends in methamphetamine use among Black GBMSM in Atlanta, Georgia, and (2) examine the risk environment (micro-, meso‑ and macro-level factors operating in the political, social, physical, economic, and healthcare environments) that might elevate risk for methamphetamine use in this population. MethodsWe conducted a qualitative study consisting of eight focus groups with 54 key informants between December 2019 and March 2020. Participants represented community-based and healthcare organizations that work closely with Black GBMSM. Our thematic analysis included an iterative, team coding approach combining deductive and inductive elements. ResultsParticipants unanimously agreed that methamphetamine use was increasingly prevalent among Black GBMSM in Atlanta, with many describing a historical arc in which methamphetamine use – previously associated with predominantly white, affluent GBMSM – was now common among younger, lower socioeconomic status Black GBMSM. At the micro-level, participants described contributors to increasing methamphetamine use including use as a sex drug, and the interrelated burdens of stress and mental illness, housing instability, geographic mobility and poverty. At the meso‑level, participants described virtual and physical sex scenes including use of geosocial networking apps that facilitated the spread of methamphetamine use in the Black GBMSM community. At the macro-level, participants described how policies prioritizing other concerns (e.g., HIV, opioids) seemed to limit resources available for methamphetamine prevention and treatment programming. ConclusionMulti-level environmental influences are working together to elevate risk for methamphetamine use among Black GBMSM in Atlanta, with potential to adversely impact health and well-being and undermine HIV prevention and treatment efforts.

1701. Added Benefits of Pre-exposure Prophylaxis Use on HIV Incidence with Minimal Changes in Efficiency in the Context of High Treatment Engagement among Men Who Have Sex with Men

BackgroundAlthough there is ongoing debate over the need for substantial increases in PrEP use when antiretroviral treatment confers the dual benefits of reducing HIV-related morbidity and mortality and the risk of HIV transmission, no studies to date have quantified the potential added benefits of PrEP use in settings with high treatment engagement across variable sub-epidemics in the United States.MethodsWe used a previously published agent-based network model to simulate HIV transmission in a dynamic network of 17,440 Black/African American and White MSM in Atlanta, Georgia from 2015 to 2024 to understand how the magnitude of reductions in HIV incidence attributable to varying levels of PrEP use (0–90%) changes in potential futures where high levels of treatment engagement (i.e. the UNAIDS ‘90-90-90’ goals and eventual ‘95-95-95’ goals) are achieved and maintained, as compared to current levels of treatment engagement in Atlanta (Figure 1).Model inputs related to HIV treatment engagement among Black/African American and White men who have sex with men in Atlanta. A comparison of current levels of treatment engagement (Panel A) to treatment engagement at ‘90-90-90’ (Panel B) and ‘95-95-95’ goals (Panel C).ResultsEven at achievement and maintenance of ‘90-90-90’ goals, 75% PrEP coverage reduced incidence rates by an additional 67.9% and 74.2% to 1.53 (SI: 1.39, 1.70) and 0.355 (SI: 0.316, 0.391) per 100 person-years for Black/African American and White MSM, respectively (Figure 2), compared to the same scenario with no PrEP use. Additionally, an increase from 15% PrEP coverage to 75% under ‘90-90-90’ goals only increased person-years of PrEP use per HIV infection averted, a measure of efficiency of PrEP, by 8.1% and 10.5% to 26.7 (SI: 25.6, 28.0) and 73.3 (SI: 70.6, 75.7) among Black/African American MSM and White MSM, respectively (Figure 3). Overall (Panel A) and race-stratified (Panel B and Panel C) marginal changes in HIV incidence over ten years among Black/African American and White men who have sex with men in Atlanta across scenarios of varied levels of treatment engagement among agents living with HIV infection and levels of pre-exposure prophylaxis use among HIV-uninfected agents. Note: All changes are calculated within each set of treatment scenarios relative to a scenario where no agents use pre-exposure prophylaxis. Person-years of pre-exposure prophylaxis use per HIV infection averted among Black/African American (Panel A) and White (Panel B) men who have sex with men in Atlanta across scenarios of varied levels of treatment engagement among agents living with HIV infection and levels of pre-exposure prophylaxis use among HIV-uninfected agents. Note: The number of HIV infections averted is calculated within each set of treatment scenarios relative to a scenario where no agents use pre-exposure prophylaxis. ConclusionEven in the context of high treatment engagement, substantial expansion of PrEP use still contributes to meaningful decreases in HIV incidence among MSM with minimal changes in person-years of PrEP use per HIV infection averted, particularly for Black/African American MSM.Disclosures All Authors: No reported disclosures

Disseminated Effects in Agent-Based Models: A Potential Outcomes Framework and Application to Inform Preexposure Prophylaxis Coverage Levels for HIV Prevention.

Preexposure prophylaxis (PrEP) for prevention of human immunodeficiency virus (HIV) infection may benefit not only the person who uses it but also their uninfected sexual risk contacts. We developed an agent-based model using a novel trial emulation approach to quantify disseminated effects of PrEP use among men who have sex with men in Atlanta, Georgia, from 2015 to 2017. Model components (subsets of agents connected through partnerships in a sexual network but not sharing partnerships with any other agents) were first randomized to an intervention coverage level or the control group; then, within intervention components, eligible agents were randomized to receive or not receive PrEP. We calculated direct and disseminated (indirect) effects using randomization-based estimators and report corresponding 95% simulation intervals across scenarios ranging from 10% coverage in the intervention components to 90% coverage. A population of 11,245 agents was simulated, with an average of 1,551 components identified. When comparing agents randomized to no PrEP in 70% coverage components with control agents, there was a 15% disseminated risk reduction in HIV incidence (risk ratio = 0.85, 95% simulation interval:0.65, 1.05). Persons not on PrEP may receive a protective benefit by being in a sexual network with higher PrEP coverage. Agent-based models are useful for evaluating possible direct and disseminated effects of HIV prevention modalities in sexual networks.

Intersecting Barriers to PrEP Awareness and Uptake in Black Men Who Have Sex with Men in Atlanta, GA: a Syndemic Perspective

Pre-exposure prophylaxis (PrEP) can sharply reduce HIV transmission risk, yet has not been widely adopted among those at highest risk for HIV, including Black men who have sex with men (BMSM). To better understand the evolving landscape of PrEP uptake in this at-risk population, we sought to examine psychosocial factors associated with PrEP uptake in a sample of BMSM residing in the Atlanta, GA, area. BMSM were recruited through online social media, LGBT venues, and participant referral, and self-reported demographic and psychosocial information via computer-assisted self-interview. Multivariate logistic regression was used to examine psychosocial factors associated with PrEP uptake. In 293 BMSM, most (N = 260; 88.7%) reported awareness of PrEP yet few (N = 30; 10.1%) reported ever having taken PrEP. BMSM reporting more syndemic conditions were less likely to be current PrEP users (OR = 0.59; 95% CI: 0.36, 0.96). BMSM reporting recent condomless anal sex (CAS) with a partner met online (adjusted odds ratio (aOR) = 2.53; 95% CI: 1.07, 5.93), or who reported having chlamydia (aOR = 8.21; 95% CI: 1.42, 47.67) or STI-related symptoms (aOR = 4.35; 95% CI: 1.32, 14.37) in the past 3months, or genital warts in their lifetime (aOR = 7.74; 95% CI: 2.47, 24.21) were more likely to have ever used PrEP. Sexual orientation stigma from health care providers was negatively associated with PrEP uptake (OR = 0.81, 95% CI: 0.68, 0.95) among BMSM reporting recent CAS and multiple partners. Syndemic and stigma theories may inform strategies for improving PrEP uptake in BMSM.

Shigellosis Among Gay and Bisexual Men: A Qualitative Assessment to Examine Knowledge, Attitudes, and Practices.

Shigellosis is a highly contagious enteric bacterial disease transmitted through the fecal-oral route. It is primarily transmitted through person-to-person contact and via contaminated food and water. Outbreaks of shigellosis among men who have sex with men (MSM) attributed to sexual person-to-person contact have been reported. These outbreaks are of concern because they are often caused by multidrug-resistant strains of Shigella. Little is known about shigellosis-related knowledge, attitudes, and practices among gay, bisexual, and other MSM. Six focus groups were conducted among self-identified gay or bisexual men in Atlanta, GA, in Fall 2017. Participants were asked about shigellosis-related knowledge, attitudes, and practices. Focus groups were audio recorded, and the transcribed audio was analyzed using inductive and deductive thematic coding. Among the 24 focus group participants, most perceived that diarrheal illness was caused by contaminated food. Knowledge of shigellosis and Shigella was low, with most never having heard of the disease or bacteria. Participants did not perceive shigellosis to be a serious health concern, especially when compared with HIV; however, they did perceive gay and bisexual men to be at risk of Shigella infection. Participants reported mixed intentions to change sexual behaviors to prevent shigellosis or talk with sexual partners about diarrhea. Health communication and education efforts could be used to increase knowledge about shigellosis and shift perceptions about the severity of shigellosis among gay, bisexual, and other MSM. Additional work is needed to identify effective ways to promote shigellosis-related prevention behaviors among gay, bisexual, and other MSM.

Health Care-Seeking Behaviors and Perceptions of Provider-Initiated Discussion of Pre-exposure Prophylaxis Among PrEP-Naïve HIV-Negative Men Who Have Sex With Men in Atlanta, Georgia.

BackgroundGiven high rates of HIV among men who have sex with men (MSM) in the United States, there is a need to more effectively leverage the health care system to bolster promotion of pre-exposure prophylaxis (PrEP) to at-risk MSM.MethodsUsing data collected from a 2018 venue-based cross-sectional survey, we examined factors associated with health care–seeking behaviors, discussing PrEP with a provider, and barriers to PrEP uptake among MSM. Associations between outcomes and respondents’ sociodemographic characteristics and sexual behaviors were assessed using log binomial regression.ResultsOf 478 MSM, 247 (51%) were PrEP-naïve and HIV-negative. Although 85% of PrEP-naïve MSM reported visiting a health care provider in the past year, only 31% recalled having any provider discuss PrEP. The most frequently cited reasons for not taking PrEP were low perception of personal risk of acquiring HIV (37%) and not knowing enough about PrEP (35%). Those who saw a provider in the last year were less likely than those who did not to cite lack of knowledge as a barrier to use (prevalence rate, 0.66, 95% confidence interval, 0.45–0.96).ConclusionsDespite the majority of PrEP-naïve MSM interfacing with the health care system, recollection of discussing PrEP with providers was limited. Increased efforts to equip providers with the tools to discuss PrEP and address pressing concerns with at-risk individuals may help improve PrEP uptake among priority populations.

Transactional Sex and Incident Chlamydia and Gonorrhea Among Black Men Who Have Sex With Men in Atlanta, Georgia.

Black men who have sex with men (BMSM) are disproportionately affected by sexually transmitted infections (STI), including chlamydia and gonorrhea. Transactional sex is an hypothesized risk factor for STI acquisition in BMSM. We estimated the association of transactional sex with incident chlamydia/gonococcal infection among BMSM using longitudinal data from a randomized trial in Atlanta (2012-2015). BMSM were eligible for inclusion if they tested human immunodeficiency virus (HIV)-antibody-negative and reported both ≥2 male sex partners and any condomless anal sex in the last year. We defined chlamydia/gonorrhea incidence as the first occurrence of either rectal or urogenital chlamydia or gonococcal infections after a negative result at enrollment. We used Poisson regression to estimate the incidence rate (IR) for chlamydia/gonorrhea over 12 months. Incidence rate ratios (IRR) compared estimates by reported experience of transactional sex. Subgroup analyses assessed potential heterogeneity by age and sexual identity. This analysis included 416 BMSM, of whom 191 (46%) were gay-identified, 146 (42%) reported a history of transactional sex, and 57 (14%) had prevalent chlamydia/gonococcal infection at baseline. Over a median of 1 year of follow-up, an additional 55 men tested laboratory-positive for chlamydia/gonorrhea (IR, 17.3 per 100 person-years). Transactional sex was not associated with chlamydia/gonorrhea incidence overall. However, among gay-identified BMSM, transactional sex was associated with incident chlamydia/gonorrhea (IRR, 2.9; 95% confidence interval, 1.2-6.8). Economic and social vulnerabilities may motivate engagement in high-risk sexual behaviors through commodified sex, potentially increasing the burden of STIs among BMSM. In this investigation, the relationship between transactional sex and chlamydia/gonorrhea was not homogenous across BMSM with diverse sexual identities in Atlanta, suggesting that within select sexual networks, transactional sex may drive STI risks. Delivering accessible and targeted STI screening for marginalized BMSM should be prioritized for STI and HIV prevention.

Housing Instability, Depression, and HIV Viral Load Among Young Black Gay, Bisexual, and Other Men Who Have Sex With Men in Atlanta, Georgia.

Housing instability is common among sexual minority youth. Research suggests that psychological distress, such as depression, may mediate the association between housing instability and poor HIV-related outcomes, but this hypothesis remains underexplored. Housing instability was assessed using two variables (residential moves in 6 months, and self-reported homelessness at any time since age 15 years). We examined cross-sectional relationships between the housing instability variables and detectable HIV-1 viral load (VL) in a sample of young Black gay, bisexual, and other men who have sex with men (YB-GBMSM) living with HIV (N = 81) in Atlanta, GA, in 2015-2016. Additionally, we explored whether depressive symptoms mediated this relationship. Our exploratory study suggests that psychological distress may partially mediate the association between housing instability and detectable VL. In addition to structural interventions that ensure housing stability, increasing use of mental health services by unstably housed YB-GBMSM may improve VL suppression in this high-risk population.

Lack of health insurance is associated with delays in PrEP initiation among young black men who have sex with men in Atlanta, US: a longitudinal cohort study.

IntroductionDelays between receiving a PrEP prescription and taking a first dose increase the risk of HIV infection. This is especially relevant in populations with high HIV incidence, such as young black men who have sex with men (YBMSM) in the United States. Additionally, YBMSM have relatively low levels of health insurance. We investigated whether lack of health insurance and reliance on PrEP funding through the manufacturer assistance programme (MAP) leads to delays in initiation of PrEP.MethodsHIV‐negative YBMSM were offered PrEP as part of a prospective cohort. Enrolment began in June 2015 with follow‐up through February 2019. Interested participants attended a PrEP clinician visit and received a prescription. Those with health insurance received a copay assistance card; those without insurance accessed PrEP using the MAP. The primary outcome was the days between prescription and initiation. The effect of insurance status on this delay was modelled using a Cox proportional hazards model.Results and DiscussionThe median delay between receipt of a PrEP prescription and taking a first dose was 12 days (IQR 3 to 32). Compared to uninsured participants, the adjusted hazard ratio for PrEP initiation for those with insurance was 2.72 (95% CI 1.82 to 4.06). The adjusted median time to initiation for insured participants was 5 days versus 21 days for those without insurance (p < 0.0001). Older age and STI diagnosis were also associated with faster PrEP initiation. Despite equivalent access to PrEP provided by the study, YBMSM without insurance had longer delays in initiation after receipt of a prescription. Overall, the observed delay in PrEP initiation increases the chances of HIV infection and the possibility of PrEP initiation after undetected seroconversion.ConclusionsThe extended time period between PrEP prescription and taking a first dose increases the risk of HIV transmission. Younger YBMSM and those without health insurance had longer delays in PrEP initiation. Immediate PrEP initiation programmes could decrease the likelihood of this occurrence and mitigate the disparity in initiation between those with and without health insurance.

Pre-exposure Prophylaxis Uptake and Discontinuation Among Young Black Men Who Have Sex With Men in Atlanta, Georgia: A Prospective Cohort Study.

Human immunodeficiency virus (HIV) preexposure prophylaxis (PrEP) has great potential to reduce HIV incidence among young black men who have sex with men (YBMSM); however, initiation and persistence for this group remain low. We sought to understand the patterns and predictors of PrEP uptake and discontinuation among YBMSM in Atlanta, Georgia. PrEP was offered to all participants in a prospective cohort of YBMSM aged 18-29 years not living with HIV. Time to PrEP uptake, first discontinuation, and final discontinuation were assessed using the Kaplan-Meier method. Cox proportional hazard models were used to identify predictors of uptake and discontinuation. After 440 person-years of follow-up, 44% of YBMSM initiated PrEP through the study after a median of 122 days. Of PrEP initiators, 69% had a first discontinuation and 40% had a final discontinuation during the study period. The median time to first PrEP discontinuation was 159 days. Factors associated with PrEP uptake included higher self-efficacy, sexually transmitted infection (STI), and condomless anal intercourse. Factors associated with discontinuation included younger age, cannabis use, STI, and fewer sex partners. HIV incidence was 5.23/100 person-years (95% confidence interval [CI], 3.40-7.23), with a lower rate among those who started PrEP (incidence rate ratio, 0.39; 95% CI, .16-.92). Persistent PrEP coverage in this cohort of YBMSM was suboptimal, and discontinuations were common despite additional support services available through the study. Interventions to support PrEP uptake and persistence, especially for younger and substance-using YBMSM, are necessary to achieve full PrEP effectiveness. NCT02503618.
