HIV testing and pre-exposure prophylaxis (PrEP) use, familiarity, and attitudes among gay and bisexual men in the United States: A national probability sample of three birth cohorts

Pre-exposure prophylaxis engagement among sexual minority men in Taiwan: a behavioral health perspective

In Taiwan, sexual minority men (SMM) account for a significant portion of new HIV cases, highlighting the need for effective prevention measures. However, pre-exposure prophylaxis (PrEP) use remains limited, necessitating a comprehensive examination of barriers. This study examined PrEP engagement and its predictors among 284 SMM in Taiwan. Participants were categorized into five stages, based on the Transtheoretical Model of Health Behavior Change, reflecting distinct levels of PrEP engagement. Ordinal logistic regression, informed by the Behavioral Model of Health Service Use, identified factors associated with being positioned at higher stages of the cascade. Significant predictors of PrEP engagement included predisposing (i.e., relationship status), enabling (i.e., PrEP knowledge, community connectedness), and need factors (i.e., number of sexual partners, chemsex). Findings highlight the need for further research on education, relationship dynamics, and sexual risk behaviors to inform tailored interventions that enhance PrEP engagement among SMM in Taiwan and the broader Asia region.

Exploring determinants of pre-exposure prophylaxis awareness and willingness among sexual minority men in Taiwan: a stochastic search variable selection approach

Since the introduction of pre-exposure prophylaxis (PrEP) in Taiwan in 2016, understanding factors influencing awareness and willingness among sexual minority men (SMM) remains critical. This study investigated predictors of PrEP awareness and willingness among SMM in Taiwan. A cross-sectional online survey conducted between April and May 2023 included 379 HIV-negative or status-unknown cisgender men identifying as gay, bisexual, or men who have sex with men, aged 18-59. Using stochastic search variable selection (SSVS), regression models identified key factors associated with PrEP awareness and willingness. Results revealed high awareness (96.9%) but moderate willingness (75.5%) to use PrEP. Regular HIV/STI testing, using apps to find sex partners, and community affinity significantly predicted both awareness and willingness. Additionally, internalized stigma, higher education, financial stress, and sexualized substance use were linked to awareness, while enacted stigma and PrEP awareness were associated with willingness. These findings highlight the need for targeted strategies to address stigma and barriers to awareness and willingness. Leveraging digital platforms and fostering community engagement are essential for strengthening these critical precursors in HIV prevention among SMM in Taiwan.

Factors Associated with PrEP Stigma Among Gay, Bisexual, and Other Men Who Have Sex with Men (gbMSM): A Systematic Review

Gay, bisexual, and other men who have sex with men (gbMSM) are disproportionately affected by HIV. While pre-exposure prophylaxis (PrEP) is highly effective at preventing HIV acquisition, uptake of PrEP among gbMSM is low, which may in part be due to stigma associated with PrEP use. This systematic review aimed to explore experiences of PrEP stigma and to identify factors associated with this. Four databases were searched for papers including terms relating to (i) gbMSM, (ii) PrEP, and (iii) stigma, with narrative synthesis used to analyze results. After screening, 70 studies were included in the final analysis. Experiences of PrEP stigma were found to be characterized by a number of stereotypes and came from a range of sources. Five categories of factors were associated with stigma: (i) healthcare-related factors, (ii) cultural and contextual factors, (iii) sociodemographic factors, (iv) peer-discussion, and (v) psychosocial factors. These findings suggest that stigma can be a common experience for gbMSM. However, some are more at risk than others. Interventions aimed at reducing PrEP stigma may be useful in increasing uptake.

Perceived risks and benefits of telePrEP interventions: An interview study with rural sexual minority men in Texas

PURPOSE

Many rural areas lack brick-and-mortar HIV prevention resources despite the increasing rates of HIV. Although online HIV pre-exposure prophylaxis (PrEP) programs can potentially increase uptake among rural sexual minority men (SMM), their attitudes and preferences regarding telehealth-based PrEP (telePrEP) programming are uncertain. This qualitative study examined rural SMM's perceived risks and benefits of participating in a hypothetical telePrEP program.

METHODS

Twenty rural SMM living in Texas completed a semi-structured online videoconferencing interview between April 12 and June 14, 2023. Data were analyzed with reflexive thematic analysis.

FINDINGS

Four themes were constructed: (1) telePrEP interventions increase accessibility but completely online services might be inadequate; (2) telePrEP and mail-order interventions are convenient but face challenges; (3) telePrEP interventions need to address confidentiality and privacy within the context of the sociopolitical climate; and (4) telePrEP interventions need to address trustworthiness and transparency.

CONCLUSIONS

Overall, our results indicate that rural SMM perceive telePrEP interventions that provide at-home and telehealth PrEP, HIV testing, and HIV care services as beneficial. However, overall utility and acceptability depend on perceptions of privacy, confidentiality, trustworthiness, and transparency. Given the HIV prevention and treatment service deserts in which many rural SMM live, telePrEP interventions must purposefully demonstrate how their operations and data will remain safe and secure. Further work should explore contextual or situational factors that influence the willingness and acceptability of rural SMM to participate in online HIV prevention intervention research studies.

Determinants and acceptability of HIV self-testing among vulnerable groups in sub-Saharan Africa: A scoping review protocol

INTRODUCTION

HIV self-testing (HIVST) is where individuals collect their specimens and perform the HIV test privately. HIVST has improved testing uptake and coverage, especially among vulnerable groups of sub-Saharan Africa (SSA). Vulnerable groups include key populations such as men who have sex with men, sex workers, people who inject drugs, lesbian, gay, bisexual and transgender persons and young women. However, little is known about the determinants and acceptability of HIVST among these groups in SSA. Therefore, this scoping review aims to explore the determinants and acceptability of HIVST among vulnerable groups in SSA.

METHODS

A scoping review will be conducted using the Arksey and O'Malley framework and further refined by Levac framework. The review will follow a six-step approach: (1) identifying the research question, (2) identifying relevant studies, (3) study selection eligibility, (4) charting the data, (5) collating, summarising and reporting the results and (6) consultation. A comprehensive search strategy will be developed, and the following electronic databases will be searched: MEDLINE, Embase, Global Health and the Cochrane Library. Grey literature will also be searched, including conference abstracts and reports. Eligibility criteria will include studies conducted in SSA, published between 2010 and 2023, focusing on vulnerable groups and exploring the determinants and acceptability of HIVST. Two independent reviewers will screen identified studies' titles, abstracts and full texts. Any disagreements will be resolved through discussion or consultation with a third reviewer. Data extraction will be conducted using a standardised form.

ETHICS AND DISSEMINATION

This review, not requiring ethical approval, aims to inform policy and intervention design to boost HIV testing adoption within vulnerable communities. We plan to disseminate our findings via a peer-reviewed journal, policy briefs, conference presentations and stakeholder engagement.

Opportunities to Increase Access to HIV Prevention: Evaluating the Implementation of Pharmacist-Initiated Pre-exposure Prophylaxis in California

Background

Pharmacies are a promising setting through which to expand access to human immunodeficiency virus (HIV) prevention, including pre-exposure and post-exposure prophylaxis (PrEP and PEP, respectively). We aimed to evaluate and inform the implementation of California's Senate Bill 159 (2019), allowing pharmacists to independently prescribe PrEP and PEP.

Methods

From October through December 2022, we conducted a cross-sectional study of 919 California pharmacists and pharmacy students, primarily recruited via the email listservs of professional organizations. Participants completed an online survey assessing the implementation of pharmacist-initiated PrEP/PEP, including knowledge, attitudes, practices, perceived barriers, and implementation preferences elicited through a discrete choice experiment.

Results

Among 919 participants (84% practicing pharmacists, 43% in community pharmacies), 11% and 13% reported that pharmacists at their pharmacy initiate PrEP and PEP, respectively. Most believed that pharmacist-initiated PrEP/PEP is important (96%) and were willing to provide PrEP (81%); fewer (27%) had PrEP/PEP training. Common implementation barriers were lack of staff/time and payment for pharmacist services. Participants preferred PrEP implementation models with in-pharmacy rapid oral HIV testing and pharmacists specifically hired to provide PrEP services.

Conclusions

Despite pharmacists' supportive attitudes, Senate Bill 159 implementation in California pharmacies remains limited, in part due to policy-level and organizational-level barriers. Ensuring PrEP/PEP-related payment for services and sufficient workforce capacity is key to leveraging pharmacists' role in HIV prevention.

"This Is To Help Me Move Forward": The Role of PrEp in Harnessing Sex Positivity and Empowerment Among Black Sexual Minority Men in the Southern United States

In the United States (U.S.), Black sexual minority men (BSMM) are disproportionately burdened by HIV. Prevention advances, such as HIV pre-exposure prophylaxis (PrEP), play a key role in reducing HIV transmission and improving our understanding of sexual expression and health. Despite these advances, little is known regarding the potential link between PrEP use and positive sexuality, including the benefits that BSMM see in accessing PrEP. We conducted a thematic analysis of 32 interviews with BSMM in the Southern U.S. regarding their PrEP beliefs. We developed five themes: (1) Sexual freedom, (2) Agency and empowerment, (3) Making PrEP normative, (4) Behavioral health practices, and (5) Committed relationship tensions. Our findings suggest that BSMM are increasingly concerned about freedom of choice and invested in sexual empowerment as related to their PrEP use. Further, unanticipated benefits, community support, and relationship tensions are salient factors in considerations of PrEP use among BSMM. These findings have implications for how we might understand a broader movement toward sexual empowerment and positivity, and the pivotal role that PrEP serves in this movement.

Variations in Pre-exposure Prophylaxis (PrEP) Awareness and Healthcare Provider Interactions in a Nationally Representative Sample of American Men Aged 15-49 Years: A Cross-Sectional Study

Awareness of and discussions with a healthcare provider (HCP) around pre-exposure prophylaxis (PrEP), an effective HIV prevention method, are associated with PrEP uptake, yet few studies utilize representative samples or report on these outcomes using distinct behavioral risk subgroups. This cross-sectional study utilized responses given by men on the 2017-2019 National Survey of Family Growth, a nationally representative survey of Americans aged 15-49 years. Multiple logistic regression models were used to determine how respondents' sociodemographic characteristics and HIV risk behaviors were related to PrEP awareness and HCP discussions. PrEP awareness was low (29.40%) as was the proportion who reported ever discussing PrEP with an HCP (4.48%). Odds of being PrEP aware and discussing PrEP with an HCP varied significantly within sexual behavior subgroups based on sociodemographic and behavioral characteristics highlighting the differential risks within distinct behavioral subgroupings of men. Sexual behavior subgroupings should be considered when promoting PrEP awareness and discussions as HIV risk behaviors vary considerably and sexual identity alone may not sufficiently capture one's HIV risk.

Intersectional Discrimination and PrEP uSe Among Young Black Sexual Minority Individuals: The Importance of Black LGBTQ Communities and Social Support

Intersectional stigma and discrimination have increasingly been recognized as impediments to the health and well-being of young Black sexual minority men (YBSMM) and transgender women (TW). However, little research has examined the relationship between intersectional discrimination and HIV pre-exposure prophylaxis (PrEP) outcomes. This study with 283 YBSMM and TW examines the relationship between intersectional discrimination and current PrEP use and likelihood of future PrEP use. Path models were used to test associations between intersectional discrimination, resilience and social support, and PrEP use and intentions. Individuals with higher levels of anticipated discrimination were less likely to be current PrEP users (OR = 0.59, p = .013), and higher levels of daily discrimination were associated with increased likelihood of using PrEP in the future (B = 0.48 (0.16), p = .002). Greater discrimination was associated with higher levels of resilience, social support, and connection to the Black LGBTQ community. Social support mediated the effect of day-to-day discrimination on likelihood of future PrEP use. Additionally, there was a significant and negative indirect effect of PrEP social concerns on current PrEP use via Black LGBTQ community connectedness. The results of this study highlight the complexity of the relationships between discrimination, resilience, and health outcomes.

Correlates of HIV Testing across the lifespan - adolescence through later adulthood - among sexual minority men in the US who are not on PrEP

Regular HIV testing is an essential component of the HIV prevention and care cascade. Sexual minority males (SMM) account for most new HIV infections in the US and testing rates among SMM vary substantially across the lifespan. Research has largely overlooked the developmental context of HIV testing. The current study compared correlates of HIV testing among adolescents (aged 13-17; n = 1,641), emerging adults (aged 18-29; n = 50,483), early adults (aged 30-39; n = 25,830), middle adults (aged 40-64; n = 25,326), and late adults (65 and older; n = 1,452) who were recruited online. Overall, HIV testing rates were lowest among adolescent SMM. Having condomless anal sex in the past 3-months was a consistentpredictor of HIV testing across all age cohorts.The association between relationship status and frequency of HIV testing varied across ages. Being in a non-monogamous relationship (versus single) was associated with more frequent HIV testing among adolescent and emerging adult SMM , while being in a monogamous relationship (versus single) was associated with lower odds of HIV testing among early, middle, and late adults.

Who is using PrEP on-demand? Factors associated with PrEP use modality among Black and Hispanic/Latino emerging adults

Pre-exposure prophylaxis (PrEP) is a highly efficacious HIV prevention medication, yet Black and Hispanic/Latino sexual minority men's and gender diverse individuals' (SMMGD) PrEP use is limited due to factors such as PrEP barriers and anticipated PrEP stigma. Although most individuals who use PrEP take it as a daily regimen, there is evidence that many SMMGD are interested in using "on-demand" (also known as event-driven or intermittent or 2-1-1) PrEP. We used stepwise multinomial logistic regression to explore factors associated with on-demand, daily, and no PrEP use among 820 Black and Hispanic/Latino SMMGD ages 18-29 in the United States. We found that greater reported PrEP barriers were associated with higher odds of using PrEP on-demand or not using PrEP compared to daily PrEP use. More past 3-month sex partners and greater comfort telling others about PrEP use were associated with lower odds of on-demand compared to daily PrEP use. In addition, compared to daily PrEP use, more past 3-month sex partners, greater comfort telling others about PrEP use, and higher anticipated PrEP stigma were associated with lower odds of no current PrEP use compared to daily PrEP use. Findings may inform clinical practices and interventions to promote PrEP uptake and adherence.

Exploring drivers of pre-exposure prophylaxis uptake among gay, bisexual, and other men who have sex with men in Malaysia

BACKGROUND

Pre-exposure prophylaxis (PrEP) is a valuable HIV prevention strategy, particularly among men who have sex with men (MSM); however, PrEP uptake is below the threshold needed to curb the HIV epidemic among this group, especially in settings like Malaysia, where same-sex sexual behavior is illegal.

METHODS

A sample of 355 participants completed an online survey between June and July 2020, recruited through geosocial networking apps for MSM and social networking websites (e.g. Facebook). We used descriptive and multivariable analyses to examine correlates of PrEP use within this population.

RESULTS

The sample was predominantly Malay (53.5%), had monthly incomes greater than RM 3000 (USD 730) (52.7%), and a tertiary level of education (84.5%). About 80% of participants heard of PrEP prior to the survey, with significantly less (18.3%) having ever taken PrEP. In the adjusted multivariable logistic model, using drugs before or during sexual intercourse ("chemsex") (AOR: 3.37; 95% CI: 1.44-7.89), being diagnosed with a sexually transmitted infection in the last 12 months (AOR: 2.08; 95% CI: 1.13-3.85), HIV testing in the previous 6 months (AOR: 3.23; 95% CI: 1.74-5.99), and disclosure of sexual orientation (AOR: 1.85; 95% CI: 1.02-3.34) were associated with having taken PrEP in the past.

CONCLUSIONS

This study revealed that PrEP use among Malaysian MSM is relatively low, despite high awareness, and is associated with healthcare engagement and high-risk behaviors. These results highlight the need to tailor outreach activities for individuals at increased risk for HIV and those disengaged with the health system.

Online Sexual Health Information Seeking Patterns Differentiated by Social Location and Physical Location among Gay and Bisexual Men in Ontario, Canada

Objective

This research aimed to understand the varying needs of diverse gay and bisexual men (GBM) in relation to online sexual health information-seeking dependent upon differing social sociodemographic variables and geographic location.

Methods

A total of 1802 GBM in Ontario participated in this study. Multivariable regressions were conducted to analyze differences in information-seeking based on ethnicity group, HIV status, recent sexual behavior and regionality (urban and rural location).

Results

There were significant differences in online sexual health information-seeking content based on these demographic variables.

Conclusions

Implications for sexual health outreach and service provision for diverse GBM are discussed as well.

"White, Tall, Top, Masculine, Muscular": Narratives of Intracommunity Stigma in Young Sexual Minority Men's Experience on Mobile Apps

What forms of intracommunity stigma do young sexual minority men narrate as they participate in communities through mobile apps? In a content analysis of 32 interviews with a racially diverse sample of young sexual minority men (ages 19-25; 84.4% non-White) from four regions of the USA, a majority of men (62.5%) spontaneously discussed mobile apps (e.g., Grindr, Scruff) when asked about their experience of community more broadly. Men's narratives revealed engagement with intracommunity stigma related to body size, race/ethnicity, gender expression, and sexual position (e.g., bottom). Stigma related to HIV status, substance use, and social class were not spontaneously narrated in response to questions about men's experience in communities. Expressions of stigma were frequently experienced intersectionally, particularly regarding racialized stereotype expectations (e.g., "Asian men are twinks, effeminate"). We discuss the ways in which sexual minority men reproduce dominant ideologies related to racism, misogyny, and masculine body ideals as they engage with one another on mobile apps. To the extent that many young men rely on mobile apps for community connection, their experiences of community might serve to exacerbate, rather than ameliorate, the deleterious impact of stigma.

Assumptions about patients seeking PrEP: Exploring the effects of patient and sexual partner race and gender identity and the moderating role of implicit racism

Introduction

Daily pre-exposure prophylaxis (PrEP) for HIV-prevention is an essential component of national plans to end the HIV epidemic. Despite its well-documented safety and effectiveness, PrEP prescription has not met the public health need. Significant disparities between White and Black people exist with respect to PrEP prescription, as do disparities between men and women. One factor contributing to these disparities is clinicians’ assumptions about patients seeking PrEP.

Methods

The present study sought to investigate medical students’ assumptions about patients seeking PrEP (anticipated increased condomless sex, extra-relational sex, and adherence to PrEP), and assumed HIV risk when presenting with their sexual partner. We systematically varied the race (Black or White) and gender (man or woman) of a fictional patient and their sexual partner. All were in serodifferent relationships including men who have sex with men (MSM), women (MSW), and women who have sex with men (WSM). Participants also completed an implicit association test measuring implicit racism against Black people. We evaluated the moderation effects of patient and partner race on assumptions as well as the moderated moderation effects of implicit racism.

Results

A total of 1,472 students participated. For MSM patients, having a Black partner was associated with higher assumed patient non-adherence to PrEP compared to a White partner, however a White partner was associated with higher assumed HIV risk. For MSW patients, a White male patient was viewed as being more likely to engage in more extra-relational sex compared to a Black male patient. For WSM patients, White women were assumed to be more likely to have condomless and extra-relational sex, be nonadherent to PrEP, and were at higher HIV risk. Overall, implicit racism was not related to negative assumptions about Black patients as compared to White patients based on patient/partner race.

Discussion

Medical education about PrEP for HIV prevention must ensure future health professionals understand the full range of patients who are at risk for HIV, as well as how implicit racial biases may affect assumptions about patients in serodifferent couples seeking PrEP for HIV prevention. As gatekeepers for PrEP prescription, clinicians’ assumptions about patients seeking PrEP represent a barrier to access. Consistent with prior research, we identified minimal effects of race and implicit racism in an experimental setting.

PrEP Familiarity, Interest, and Usage Among 364 Black and Hispanic Adults in Indiana

Pre-exposure prophylaxis, or PrEP, is a once-daily preventative prescription pill against HIV for adults or adolescents who have sex or inject drugs. PrEP may be especially useful among Black and Hispanic Americans, who are particularly at risk for HIV in the United States. In spite of this vulnerability, rates of PrEP use in Black and Hispanic communities are low. Here, we examined familiarity with, prior usage of, and future interest in PrEP among 364 Black and Hispanic Indiana residents. Indiana is an important context for this work, due to severe HIV outbreaks in the area over the last 8 years. Around half of all participants had never heard of PrEP, with Hispanic participants being less familiar than Black participants. Prior PrEP use was low, at around 10%, and was lower for Hispanic than Black participants. Around 21% of all participants reported interest in PrEP after learning of it in our study. Further, participants identified strategies that would make discussions about PrEP with a medical provider more comfortable. Black and Hispanic participants reported feeling the most comfortable with addressing PrEP usage with providers if: (a) the provider was the one who brought up the subject of PrEP, (b) there was written information available to the patient (i.e., brochures), and (c) the patient already knew they qualified for the prescription in terms of personal eligibility and insurance coverage. Additional provider and patient education, as well as openness on the part of the provider, can help to lessen the disparities associated with PrEP need and actual PrEP usage.

Othering discourse and stigma amidst the identity formation process among gays, bisexuals and other men who have sex with men on HIV pre-exposure prophylaxis (PrEP)

With the global emergence of the HIV pre-exposure prophylaxis (PrEP), questions have emerged on which ways the social identity formation process among gays, bisexuals and other men who have sex with men on PrEP arise and constitute beyond exclusive sexual orientation expressions. We conducted a content analysis with thematic categories in a PrEP online group guided by group-web affiliation and individualization approaches. Individuals identify themselves as PrEPsters as part of a PrEP club, while dealing with conflicts on serosorting sexual partners and stigmatizing reactions towards people living with HIV/AIDS (PLWH). Self-worth and othering discourses towards PLWH emerged as complex themes in men's production of identity processes across four overlapping domains: (1) self-worth as a strategy to challenge individual HIV-acquisition-related anxiety and fear, (2) group-worth and group empowerment, (3) body control and reclaiming power on sexual health, and (4) othering discourses, HIV/AIDS stigma and criminalization of PLWH. Paradoxically, internal and external discourses to the group constitute and challenge identity differentiation; individuals on PrEP claim to fight against the HIV/AIDS stigma, while this reverberates alongst HIV-related discriminatory expressions in their discourses.

Lost in translation: College students' knowledge of HIV and PrEP in relation to their sexual health behaviors

OBJECTIVE

Human immunodeficiency virus (HIV) is a notable public health problem among young adults. The present study examined college students' knowledge of HIV and pre-exposure prophylaxis (PrEP) in relation to their sexual health behaviors.

PARTICIPANTS AND METHOD

Participants included 1516 students who completed questionnaires on actual and perceived HIV knowledge, perceived PrEP knowledge, and sexual health behaviors.

RESULTS

While knowledge of HIV was high, knowledge of PrEP was low. Approximately 73% of the sample reported not using condoms at all times, and 41% reported never having been tested for HIV. Women, students at public schools, upper-year students, and students with higher HIV and PrEP knowledge were more likely to get tested for HIV than their counterparts. Knowledge of HIV and PrEP did not relate to condom use.

CONCLUSION

These results suggest the need for increased education about PrEP and strategies to help students translate knowledge about HIV to recommended sexual health behaviors.

Perspectives on Social Support and Stigma in PrEP-related Care among Gay and Bisexual Men: A Qualitative Investigation

Despite its effectiveness at preventing HIV, uptake of PrEP has been slow. PrEP-related stigma is a potential barrier to uptake. Social support has been found to buffer against some PrEP stigma. Unfortunately, little research has investigated the relationship between social support and PrEP-related care. In 2018, we conducted 20 semistructured interviews with MSM who use PrEP (ages 22-70). Interview questions explored social support and PrEP-related stigma, and how these and other psychosocial factors affected PrEP use and continuation. Data were analyzed using grounded theory. Social support was important in PrEP-related care and promoted adaptive behavioral responses, such as adherence to PrEP-related medical care and enhancing resilience to stress. Participants described psychosocial benefits of PrEP, such as reduced HIV-related anxiety, but some also reported that PrEP-related stigma was an additional stressor. Findings suggest that social support has significant impacts within PrEP-related care and may help buffer against stigma.

Sociodemographic and Psychological Predictors of Seeking Health Information Online among GB2M in Ontario: Findings from the #iCruise Project

Objectives

The current study examines the experiences of gay, bisexual, two-spirit and other men who have sex with men (GB2M) who use networking applications and their engagements with online sexual health outreach workers disseminating healthcare information through these digital spaces.

Methods

The iCruise study was a longitudinal mixed-methods study across Ontario, Canada which collected data on online sexual health information seeking behaviors.

Results

Results offer insight into differences in information seeking behaviors among diverse groups of queer men.

Conclusions

Implications for the dissemination of health information based on the results of information seeking patterns is discussed as well.

Psychosocial Support, Sexual Health, and HIV Risk among Older Men Who Have Sex with Younger Men

This study examines the extent to which older males are willing to offer psychosocial and sexual health promoting support to their younger male partners, as well as the individual and relationship-level factors associated with this willingness to provide support. In total, 324 men over the age of 45, who currently or previously had younger male sexual partners, completed an anonymous online survey. Results show that participants were most willing to provide emotional support to their younger male partners, followed by health-related encouragement, HIV/STI testing support, and financial support. Of note, HIV positive status and being in a "main partnership" were associated with greater willingness to provide financial support. These results suggest that older men are willing to provide psychosocial and health promotive support to younger male partners, which could be leveraged in targeted interventions to reduce HIV transmission.

Knowledge of HIV and HIV pre-exposure prophylaxis among medical and pharmacy students: A national, multi-site, cross-sectional study

Pre-exposure prophylaxis (PrEP) is a highly effective strategy for preventing HIV. However, prescription of PrEP has not reached the scale that is necessary to meet the public health need of reducing HIV incidence. A factor contributing to this slow scale-up is limited healthcare practitioners' knowledge of PrEP, making PrEP education a priority. We conducted a national, cross-sectional study of medical (allopathic and osteopathic) and pharmacy students regarding knowledge of PrEP and HIV between October 2020 and February 2021. We included 28 items in our knowledge assessment. Analysis sought to identify gaps in knowledge as well as academic and demographic correlates of knowledge. A total of 2,353 students participated in the study (response rate = 17.0%). The overall mean HIV knowledge score was 79.6% correct. Regarding specific items, 68.7% of participants believed HIV treatment was difficult because it required many pills, and 61.1% incorrectly indicated a person with an undetectable HIV viral load could transmit the virus to their sexual partners. Overall mean PrEP knowledge was 84.1%. Approximately one-third of participants did not identify HIV-negative status as a requirement to be a PrEP candidate. Gay/lesbian participants and those who were in the late-phase of training reported higher knowledge of both HIV and PrEP than did heterosexual participants and those in the early-phase of training. This study identifies specific gaps in training on HIV prevention with PrEP that must be improved in health professions education to ensure PrEP reaches its full potential in ending the HIV epidemic.

HIV Treatment Cascade and PrEP Care Continuum Among Serodiscordant Male Couples in the United States

A large proportion of HIV infections among men who have sex with men occur within primary partnerships, however, there is a lack of research focused on serodiscordant male couples. We used baseline data collected as part of Project Stronger Together-a randomized controlled trial to improve treatment outcomes among 155 serodiscordant male couples. We described engagement in HIV care/prevention using the HIV treatment cascade and PrEP care continuum. Among partners living with HIV, 86.5% were linked to care, 77.4% retained in care, 81.3% prescribed ART, 60.7% adherent, and 67.7%virally suppressed. Among HIV-negative partners, 62.6% were willing to take PrEP, 48.4% had ever taken PrEP, and 26.5% were adherent to PrEP. Black partners living with HIV had lower odds of being virally suppressed compared to White partners. Our findings provide evidence to suggest designing programs to address the racial disparities in viral suppression, addressing barriers to HIV prevention/treatment, and improving PrEP education.

Measures of HIV Pre-exposure Prophylaxis Uptake Among Gay, Bisexual, and Other Men Who Have Sex with Men in Canada and Demographic Disparities Among Those at Elevated Likelihood for HIV Acquisition

HIV pre-exposure prophylaxis (PrEP) is an effective prevention tool being scaled up in Canada. We describe PrEP uptake and identify demographic correlates of uptake among gay, bisexual, and other men who have sex with men (gbMSM) at elevated HIV risk using data from an online survey of gbMSM residing in Canada between Oct 2017 and Jan 2018. Among the 969 participants at elevated HIV risk who had recently tested for HIV, 96.0%, 83.3%, 72.6%, and 39.7% reported awareness, knowledge, acceptability, and pursuit of PrEP, respectively; 27.1% had ever and 24.6% were currently taking PrEP. The strongest correlate of PrEP uptake was living in a city of ≥ 500,000 inhabitants; others included being out to all or almost all family, friends, and colleagues regarding sexual attraction to men, greater financial coping, and being 30-49 years of age. Improved upscaling of PrEP in Canada may be accomplished through consideration of these disparities.

HIV Stigma, Homophobia, Sexual and Gender Minority Community Connectedness and HIV Testing Among Gay, Bisexual, and Other Men and Transgender People Who Have Sex with Men in Kazakhstan

Although HIV incidence is rising among gay, bisexual, and other men (MSM) and transgender people who have sex with men (TSM) in Kazakhstan, whether stigmatizing attitudes and connectedness are associated with HIV testing in this region is not known. We analyzed data from one-time interviews with 304 adult MSM and TSM conducted 2018-2019 in three cities in Kazakhstan. Logistic regression determined whether HIV stigma, internalized homophobia, sexual and gender minority (SGM) connectedness predicted HIV testing (within the lifetime, past year, and past 6 months) before and after adjustment for sociodemographic characteristics. 80% of participants reported ever receiving an HIV test. Gay-identified participants reported less HIV stigma and internalized homophobia as well as greater connectedness relative to those with bisexual or other identities. In adjusted models, those who had ever tested reported lower HIV stigma (aOR 0.83, 95% CI 0.76-0.91, P < .001) and higher connectedness (aOR 1.17, 95% CI 1.06-1.29, P = .003) than those who had not; those who had ever tested reported lower internalized homophobia in the unadjusted model only (OR 0.95, 95% CI 0.91-0.99, P = .01). Similar differences and trends were found in models examining testing in the past year and past 6 months. Addressing stigmatizing attitudes and connectedness may improve uptake of HIV testing among MSM and TSM in Kazakhstan.

Examining the Factors Affecting PrEP Implementation Within Community-Based HIV Testing Sites in Florida: A Mixed Methods Study Applying the Consolidated Framework for Implementation Research

HIV testing/counseling is a critical point during which non-clinical staff could intervene, discuss and/or refer clients for pre-exposure prophylaxis (PrEP). This analysis investigated the contextual factors affecting PrEP implementation within HIV testing sites. Two generalized linear mixed models were conducted to estimate PrEP implementation as a function of constructs from the Consolidated Framework for Implementation Research (CFIR). Qualitative interviews were analyzed thematically. Data integration occurred via joint analysis and triangulation. Constructs from the CFIR domain Characteristics of Individuals did not predict PrEP implementation when controlling for demographic characteristics; qualitative data signaled divergent findings in PrEP knowledge. Within the CFIR domains Inner and Outer Settings, relevant priority and available resources predicted PrEP implementation; qualitative data confirmed the importance of available resources and provided insight into the impact of cosmopolitanism and leadership. Addressing the contextual factors that affect PrEP implementation may help HIV testing staff to better implement PrEP programs.

Assessing the Role of Gay Community Attachment, Stigma, and PrEP Stereotypes on Young Men Who Have Sex with Men's PrEP Uptake

Negative stereotypes about pre-exposure prophylaxis (PrEP) hinder PrEP uptake among young men who have sex with men (YMSM). Prior research suggests community homophobia may be linked to negative PrEP attitudes. Conversely, individuals with high gay community attachments (GCA) may have more access to credible PrEP information/resources. Among 285 YMSM recruited online, we estimated structural equation models to test competing conceptual models that inform pathways from perceived stigmas, GCA, and negative PrEP stereotype endorsements to PrEP uptake. In Model A, perceived stigma was directly associated with PrEP uptake, partially mediated by stereotype endorsement (β =  - 0.05; 95% CI [- 0.09, - 0.01]) and GCA (β =  - 0.06; 95% CI [- 0.11, 0.02]). In Model B, perceived stigma was associated with PrEP uptake (β =  - 0.07; 95% CI [- 0.14, - 0.01]) through stereotype endorsement among high GCA YMSM. Complemented by anti-stigma initiatives, PrEP outreach for YMSM should utilize sex-positive messaging and disentangle negative PrEP stereotypes within gay-centric social spaces.

How Stigma Toward Anal Sexuality Promotes Concealment and Impedes Health-Seeking Behavior in the U.S. Among Cisgender Men Who Have Sex with Men

Gay, bisexual, and other men who have sex with men (MSM) experience alarming HIV disparities alongside sub-optimal engagement in HIV interventions. Among MSM, stigma toward anal sexuality could interfere with engagement in HIV prevention, yet few studies have examined MSM perspectives on anal sex stigma or its health-related sequelae. Guided by theory, we aimed to characterize anal sex stigma, related sexual concerns, and barriers to health seeking, like concealment. We elicited community input by purposively interviewing 10 experts in MSM health and then 25 racially, ethnically, and geographically diverse cisgender MSM. Participants reported experienced, internalized, and anticipated forms of anal sex stigma that inhibited health seeking. Experienced stigma, including direct and observed experiences as well as the absence of sex education and information, contributed to internalized stigma and anticipation of future devaluation. This process produced psychological discomfort and concealment of health-related aspects of anal sexuality, even from potentially supportive sexual partners, social contacts, and health workers. Participants characterized stigma and discomfort with disclosure as normative, pervasive, and detrimental influences on health-seeking behavior both during sex and within healthcare interactions. Omission of information appears to be a particularly salient determinant of sexual behavior, inhibiting prevention of harm, like pain, and leading to adverse health outcomes. The development of measures of anal sex stigma and related sexual concerns, and testing their impact on comfort with disclosure, sexual practices, and engagement in health services could identify modifiable social pathways that contribute to health disparities among MSM, like those seen in the HIV epidemic.

Physician Assistant's Knowledge and Confidence Regarding Prescribing Preexposure Prophylaxis for HIV Prevention

Physician assistants (PAs) have an important role to play in increasing preexposure prophylaxis (PrEP) prescriptions. We surveyed PAs regarding knowledge of Centers for Disease Control and Prevention guidelines for PrEP and confidence regarding PrEP. Physician assistants in primary care reported more accurate knowledge and higher confidence. However, knowledge and confidence gaps were present among all PAs, regardless of specialty.

Predictors of Awareness, Accessibility and Acceptability of Pre-exposure Prophylaxis (PrEP) Among English- and Spanish-Speaking Latino Men Who have Sex with Men in Los Angeles, California

Uptake of pre-exposure prophylaxis (PrEP) among Latino men who have sex with men (LMSM) remains low. We examined awareness, accessibility, acceptability and use of PrEP among LMSM. LMSM were recruited using social/sexual networking apps. Multiple Logistic regressions identified significant predictors of PrEP awareness, accessibility and acceptability. Among 276 participants, only 6% reported current PrEP use. Among non-PrEP users, 85% reported PrEP awareness, 71% indicated high likelihood of future PrEP use, but only 35% reported knowledge about accessing PrEP. In multiple logistic regressions, a lower likelihood of PrEP awareness was associated with lower level education, whereas a higher likelihood was associated with reporting 6-10 or over 10 sexual partners. A lower likelihood of PrEP accessibility was associated with lower level education and undocumented status. A lower likelihood of PrEP acceptability was associated with an income of $15,001-30,000, whereas a higher likelihood was associated with lower level education and reporting 6-10 or over 10 sexual partners. PrEP promotion targeting Latino MSM should be expanded for those with lower levels of education and those who are undocumented.

Minority stress, distress, and suicide attempts in three cohorts of sexual minority adults: A U.S. probability sample

During the past 50 years, there have been marked improvement in the social and legal environment of sexual minorities in the United States. Minority stress theory predicts that health of sexual minorities is predicated on the social environment. As the social environment improves, exposure to stress would decline and health outcomes would improve. We assessed how stress, identity, connectedness with the LGBT community, and psychological distress and suicide behavior varied across three distinct cohorts of sexual minority people in the United States. Using a national probability sample recruited in 2016 and 2017, we assessed three a priori defined cohorts of sexual minorities we labeled the pride (born 1956-1963), visibility (born 1974-1981), and equality (born 1990-1997) cohorts. We found significant and impressive cohort differences in coming out milestones, with members of the younger cohort coming out much earlier than members of the two older cohorts. But we found no signs that the improved social environment attenuated their exposure to minority stressors-both distal stressors, such as violence and discrimination, and proximal stressors, such as internalized homophobia and expectations of rejection. Psychological distress and suicide behavior also were not improved, and indeed were worse for the younger than the older cohorts. These findings suggest that changes in the social environment had limited impact on stress processes and mental health for sexual minority people. They speak to the endurance of cultural ideologies such as homophobia and heterosexism and accompanying rejection of and violence toward sexual minorities.

Health Profession Students' Awareness, Knowledge, and Confidence Regarding Preexposure Prophylaxis: Results of a National, Multidisciplinary Survey

BACKGROUND

Preexposure prophylaxis (PrEP) is a highly effective, pharmacologic method of HIV prevention. Despite its safety and efficacy, PrEP prescription remains low in those patients who are at highest risk for HIV infection. One possible reason for this may be the lack of inclusion of PrEP and HIV prevention discussions within the curricula of health professions education.

METHODS

An online survey was administered to a cross-sectional sample of future prescribers (osteopathic/allopathic medical and physician assistant students), future nurses, and future pharmacists (n = 2085) in the United States between January and July 2019 to assess and compare awareness of PrEP, PrEP education, PrEP knowledge, and confidence in 2 areas related to PrEP.

RESULTS

We show that, overall, awareness of PrEP is high among future health care providers (81.6%), with the future pharmacists reporting the greatest awareness (92.2%; P < 0.001) and more commonly reporting PrEP education (71.0%). Students had mixed knowledge of PrEP, with future pharmacists reporting the highest knowledge of PrEP. Approximately 30% of students in all disciplines reported having low confidence counseling a patient about PrEP and low confidence educating a colleague about PrEP. Knowledge of PrEP was a significant predictor of confidence counseling a patient about PrEP (P < 0.001) and educating a colleague about PrEP (P < 0.001).

CONCLUSIONS

This study identifies opportunities to improve and incorporate evidence-based strategies for educating future health care providers about PrEP for HIV prevention within health professions curricula.

Longitudinal trends in PrEP familiarity, attitudes, use and discontinuation among a national probability sample of gay and bisexual men, 2016-2018

This study explored familiarity with, attitudes toward, uptake and discontinuation of PrEP (Pre-exposure prophylaxis) among a national probability sample of gay and bisexual men. PrEP is one of the most effective biomedical HIV prevention strategies; however, use among gay and bisexual men remains low within the United States. This study used a national probability sample of gay and bisexual men from three age cohorts of men (18-25, 34-41, and 52-59 years at wave 1) who completed three annual surveys between March 2016 and March 2018 (N at wave 1 = 624). Recruitment occurred through a Gallup dual-frame sampling procedure; results for this study came from eligible individuals who consented to be part of the self-administered online or mailed survey questionnaire. We used descriptive data with sampling weights to understand trends in PrEP familiarity, PrEP attitudes and PrEP use across all three time points. Next, PrEP uptake and discontinuation were assessed among men completing all three surveys and who remained eligible for PrEP at all three time points (N = 181). PrEP familiarity increased considerably between 2016 and 2018 among those eligible for PrEP (from 59.8% from wave 1 to 92.0% at wave 3). Favorable attitudes toward PrEP increased more modestly (from 68.3% at wave 1 to 72.7% at wave 3). While PrEP use increased by 90% between the two time points (from 4.1% in 2016 to 7.8% in 2018), this represented a small percentage of overall uptake among eligible participants across time (6.6%). Among respondents who reported PrEP use at wave 1 or wave 2, 33.3% subsequently discontinued PrEP use at a later wave. Findings indicate modest increases in PrEP use between 2016 and 2018 in a national probability sample of sexually-active gay and bisexual men. PrEP discontinuation was high and suggests the need for further research into gay and bisexual men's PrEP discontinuation and persistence.

Factors associated with interest in and knowledge of pre-exposure prophylaxis (PrEP) among gay, bisexual, and other men who have sex with men (GBMSM) in the Region of Waterloo, Ontario, Canada: Insights from the OutLook Study

Pre-exposure prophylaxis (PrEP) is an effective HIV-prevention tool for gay, bisexual, and other men who have sex with men (GBMSM), a group known to be disproportionately affected by HIV/AIDS. We aimed to identify sociodemographic, psychosocial, and health factors associated with awareness of PrEP or interest in PrEP among GBMSM in a mid-sized Canadian city, where PrEP availability is arguably more scarce compared to larger metropolitan regions. The OutLook Study was a comprehensive online survey of LGBTQ health and well-being that collected data from sexual minorities aged 16+ in the Region of Waterloo, Ontario, Canada. Participants were cisgender MSM with an unknown or negative HIV status (n = 203). Bivariate logistic regression was performed to analyze factors associated with both awareness of PrEP and interest in PrEP. Multivariate logistic regression explored sexual behaviours in the past 12 months while controlling for sociodemographic and psychosocial variables. Increasing number of sexual partners (OR: 1.10; 95% CI: 1.03–1.53) was significantly associated with interest in PrEP and lifetime experiences of homophobia remained significant from the bivariate model (ORs ranged from 1.11–1.12). Since GBMSM with low educational attainment were shown to have less knowledge about PrEP, educational campaigns could be targeted in high schools rather than colleges, universities, and trade schools. Prevention initiatives should be aimed at places where single or non-monogamous GBMSM frequent due to these men being disproportionately affected by HIV/AIDS. These findings provide insights for potential interventions targeting MSM from mid-sized cities.

Student Education About Pre-exposure Prophylaxis (PrEP) Varies Between Regions of the United States

BACKGROUND

Daily, oral pre-exposure prophylaxis (PrEP) is an effective and safe prevention strategy for people at risk for HIV. However, prescription of PrEP has been limited for patients at the highest risk. Disparities in PrEP prescription are pronounced among racial and gender minority patients. A significant body of literature indicates that practicing healthcare providers have little awareness and knowledge of PrEP. Very little work has investigated the education about PrEP among health professionals in training.

OBJECTIVE

The objective of this study was to compare health professions students' awareness of PrEP and education about PrEP between regions of the US, and to determine if correlations between regional HIV incidence and PrEP use were present.

DESIGN

Survey study.

PARTICIPANTS

A cross-sectional sample of health professions students (N = 1859) representing future prescribers (MD, DO, PA), pharmacists, and nurses in the US.

KEY RESULTS

Overall, 83.4% of students were aware of PrEP, but only 62.2% of fourth-year students indicated they had been taught about PrEP at any time during their training. Education about PrEP was most comprehensive in the Northeastern US, the area with the highest PrEP to need ratio (4.7). In all regions, transgender patients and heterosexual men and women were least likely to be presented in education as PrEP candidates, and men who have sex with men were the most frequently presented.

CONCLUSIONS

There are marked differences in education regarding PrEP both between academic programs and regions of the USA.

HIV Testing and PrEP Use in a National Probability Sample of Sexually Active Transgender People in the United States

BACKGROUND

HIV testing and pre-exposure prophylaxis (PrEP) are effective HIV prevention strategies often underused by transgender people.

METHODS

Recruitment occurred in 2 phases to identify transgender respondents in a probability sample of adults in the United States. Transgender respondents completed a self-administered paper or web-based survey designed to assess transgender population health. Sexually active respondents (HIV-negative and had sex in the 5 years previously, N = 190) and a subsample of those at risk for sexual HIV acquisition (sex with cisgender men or transgender women, n = 120) were included in analyses.

RESULTS

Of the full sample of sexually active respondents, those who were transfeminine were less likely to be familiar with PrEP; most (72%) reported favorable attitudes toward PrEP. Of those at risk for HIV acquisition, 23% had never tested for HIV. Respondents of color were more likely than white respondents to meet Centers for Disease Control and Prevention recommendations for HIV testing. Respondents who met Centers for Disease Control and Prevention recommendations for HIV testing were more likely to report looking online for lesbian, gay, bisexual, and transgender or transgender-specific health information. Few respondents reported currently taking PrEP (3%); those who reported higher levels of nonaffirmation of their gender identity were less likely to currently use PrEP.

DISCUSSION

These findings may indicate some success of HIV testing outreach programs that prioritize people at higher risk for acquiring HIV, focusing on those who are vulnerable to structural marginalization. Ongoing public health efforts are needed to increase HIV testing and PrEP awareness among transgender adults, who are disproportionately impacted by HIV.

Facilitators and Barriers of Pre-exposure Prophylaxis (PrEP) Uptake Among Rural Men who have Sex with Men Living in the Midwestern U.S

Facilitators and barriers of Pre-exposure Prophylaxis (PrEP) uptake have been established in prior studies; however, most of these studies comprise samples of MSM from metropolitan cities and hypothetical PrEP use. There is a dearth of literature on the uptake factors among rural U.S. MSM who are prescribed PrEP. Thirty-four rural Midwestern MSM who currently take PrEP participated in semi-structured telephone interviews about their barriers and facilitators to their PrEP use. Interviews were analyzed using an inductive thematic analysis approach. There were four barriers: (1) lack of rural dissemination of PrEP information, (2) concern about side and adverse effects of using PrEP, (3) cost of PrEP uptake and engagement, and (4) lack of access to PrEP care and PrEP care quality. Individual and social facilitators that participants utilized to overcome these barriers are discussed. Findings elevate the importance of multilevel interventions that address PrEP adoption from a patient, provider, and healthcare system perspective.

PrEP Interest Among Men Who Have Sex with Men in the Netherlands: Covariates and Differences Across Samples

Despite increased availability of pre-exposure prophylaxis (PrEP), PrEP uptake has remained low. To promote uptake, factors related to PrEP interest among relevant target populations warrant investigation. The aim of this study was to provide an analysis of PrEP interest among men who have sex with men (MSM) in the Netherlands, while taking study recruitment strategies into account. We recruited 154 MSM from an LGBT research panel (AmsterdamPinkPanel) and 272 MSM from convenience sampling. Both samples were part of the Flash! PrEP in Europe Survey and were compared on their PrEP interest, usage intentions, and sexual behavior. We conducted logistic regression analyses to discover variables associated with PrEP interest and intentions. Participants from the AmsterdamPinkPanel were less likely to use PrEP, had less knowledge of PrEP, and were less interested in PrEP than participants from convenience sampling. Significant covariates of PrEP interest were being single, more prior PrEP knowledge, sexual risk behaviors, such as not having used a condom during last sex and having ever used drugs in a sexual context, and not participating in the AmsterdamPinkPanel. Adding the recruitment strategy to the regression increased explained variance on top of predictors already described in the literature. Increased sexual risk behavior is related to increased PrEP interest and it helps to identify PrEP target groups. Recruitment strategies have a substantial impact on findings regarding PrEP interest and usage intentions. This study emphasizes the importance of using multiple strategies for recruiting participants to obtain a more comprehensive view of MSM's attitudes toward PrEP.

The Impact of Pre-exposure Prophylaxis for Human Immunodeficiency Virus on Gonorrhea Prevalence

Pre-exposure prophylaxis (PrEP) has been shown to be highly effective in reducing the risk of HIV infection in gay and bisexual men who have sex with men (GbMSM). However, PrEP does not protect against other sexually transmitted infections (STIs). In some populations, PrEP has also led to riskier behavior such as reduced condom usage, with the result that the prevalence of bacterial STIs like gonorrhea has increased. Here, we develop a compartmental model of the transmission of HIV and gonorrhea and the impacts of PrEP, condom usage, STI testing frequency and potential changes in sexual risk behavior stemming from the introduction of PrEP in a population of GbMSM. We find that introducing PrEP causes an increase in gonorrhea prevalence for a wide range of parameter values, including at the currently recommended frequency of STI testing once every three months for individuals on PrEP. Moreover, the model predicts that a higher STI testing frequency alone is not enough to prevent a rise in gonorrhea prevalence, unless the testing frequency is increased to impractical levels. However, testing every 2 months in combination with a 10-25 % reduction in risky behavior by individuals on PrEP would maintain gonorrhea prevalence at pre-PrEP levels. The results emphasize that programs making PrEP more available should be accompanied by efforts to support condom usage and frequent STI testing, in order to avoid an increase in the prevalence of gonorrhea and other bacterial STIs.

Rectal Douching and Microbicide Acceptability among Young Men who Have Sex with Men

Men who have sex with men (MSM) commonly report engaging in rectal douching (RD) practices prior to receptive anal intercourse. Researchers are interested in the possibility of designing a RD with a microbicide component. In our analyses, we examined whether YMSM who engaged in RD behaviors differ in HIV prevention behaviors from their non-RD peers. We then examined whether RD frequency was associated with rectal microbicide acceptability. Half the participants (47.8%) reported having ever douched. Participants were more likely to douche if they were racial/ethnic minorities (AOR = 2.24, p = 0.02) and had recently tested for HIV (AOR = 1.96, p = 0.04). Greater douching frequency was associated with racial/ethnic minorities (β = 0.20, p = 0.009) and recent HIV testing (β = 0.19, p < 0.01). Participants who reported frequently douching indicated greater microbicide acceptability (β = 0.32, p < 0.001). Designing behaviorally congruent products remains a priority in next generation Pre-Exposure Prophylaxis (PrEP) and a rectal douche might be an additional tool if found to be efficacious.

Reconsidering Approaches to Estimating Health Disparities Across Multiple Measures of Sexual Orientation

Purpose: We propose a new theoretically grounded approach for estimating sexual orientation-related health risk that accounts for the unique and shared variance of sexual identity across other measures of sexual orientation (i.e., attraction and behavior). We argue and illustrate that this approach provides specificity not demonstrated by approaches that independently estimate and compare health risk based on sexual identity, attraction, and behavior. Methods: Data were from the National Epidemiologic Survey on Alcohol and Related Conditions-III, collected in 2012-2013 (N = 36,309, ages 18 and older). The Karlson-Holm-Breen method tested the degree to which attraction- and behavior-based disparities in mental health and substance use disorders change after adjusting for sexual identity. Results: Sexual attraction- and behavior-based disparities in mental health and substance use disorders statistically varied when comparing models that did and did not adjust for sexual identity. Adjusting for sexual identity appeared to have a larger influence on attraction- and behavior-based health associations among men; sexual minority and majority differences were attenuated on nearly every outcome after adjusting for sexual identity. This attenuation was less common among women. Among women, some behavior-based disparities were wider in sexual identity-adjusted models relative to unadjusted models. Conclusion: We demonstrate more accurate approaches to capturing and comparing sexual orientation-related health disparities across multiple measures of sexual orientation, which account for the shared variance between sexual identity and measures of attraction and behavior. Adjusted estimates provide more specificity regarding relative health risk across specific subgroups of sexual minority people, and the intervention and prevention strategies needed to address them.

Psychological Distress, Felt Stigma, and HIV Prevention in a National Probability Sample of Sexual Minority Men

Purpose: We assessed how psychological distress and felt stigma (perceived sexual minority stigma in one's community) are associated with key HIV prevention outcomes in a U.S. national probability sample of sexually active, HIV-negative sexual minority men. Methods: Using data from the Generations study (2017-2018, N = 285), the present study assessed the effects of psychological distress and felt stigma and their interaction on three HIV prevention outcomes: testing for HIV as per Centers for Disease Control and Prevention guidelines (once or more in the past year), use of latex barriers (e.g., condoms), and familiarity with pre-exposure prophylaxis (PrEP). Results: In main effects models, neither psychological distress nor felt stigma was associated with any of the screening and prevention outcomes. However, the interaction between psychological distress and felt stigma was associated with each outcome. Specifically, at higher levels of felt stigma, greater psychological distress was associated with lower odds of HIV testing (exponentiated coefficient = 0.93, confidence interval [95% CI] 0.87-1.00), use of latex barriers (exponentiated coefficient = 0.92, 95% CI 0.86-0.99), and familiarity with PrEP (exponentiated coefficient = 0.90, 95% CI 0.82-0.98). Conclusion: These findings highlight the importance of felt stigma in shaping the association between psychological distress and engagement in HIV screening and prevention and offer important considerations for future HIV prevention research and interventions.

Pre-exposure Prophylaxis Awareness and Use Among Cisgender Men Who Have Sex With Men and Use Methamphetamine in 3 Western US Cities

BACKGROUND

In the United States, cisgender men who have sex with men (MSM) who use methamphetamine are at substantial risk for HIV and can benefit from pre-exposure prophylaxis (PrEP).

METHODS

We used data from the National HIV Behavioral Surveillance 2017 survey from Seattle, WA; Portland, OR; and Denver, CO, to estimate PrEP awareness and use in the past 12 months among MSM who use methamphetamine. We then compared these estimates with participants who do not use methamphetamine but meet other criteria for PrEP use (i.e., condomless anal sex or a bacterial sexually transmitted infection). We explored reasons for not using PrEP and challenges using PrEP.

RESULTS

Of the 1602 MSM who participated in the 2017 National HIV Behavioral Surveillance survey in Seattle, WA; Portland, OR; and Denver, CO, 881 met the inclusion criteria for this study, of whom 88 (10%) reported methamphetamine use in the past 12 months. Most (95%) participants had heard of PrEP, and 35% had used it in the past 12 months. Pre-exposure prophylaxis awareness was lower among MSM who used methamphetamine (P = 0.01), but use was not different (P = 0.26). Among those who had not used PrEP, the most common reason for not using it was not thinking one's HIV risk was high enough (51%). Men who have sex with men who used methamphetamine were more likely to report that they were not sure PrEP would prevent them from getting HIV (38% vs. 19%, P = 0.002).

CONCLUSIONS

These results highlight the need for continued efforts to educate and promote PrEP uptake among MSM, particularly those who use methamphetamine.

Does Stigma Toward Anal Sexuality Impede HIV Prevention Among Men Who Have Sex With Men in the United States? A Structural Equation Modeling Assessment

INTRODUCTION

Men who have sex with men (MSM) are suboptimally engaged in efficacious HIV interventions, due in part to stigma.

AIM

We sought to validate the Anal Health Stigma Model, developed based on theory and prior qualitative data, by testing the magnitude of associations between measures of anal sex stigma and engagement in HIV prevention practices, while adjusting for covariates.

METHODS

We conducted a cross-sectional online survey of 1,263 cisgender MSM living in the United States and analyzed data with structural equation modeling. We tested a direct path from Anal Sex Stigma to Engagement in HIV Prevention alongside 2 indirect paths, 1 through Anal Sex Concerns and another through Comfort Discussing Anal Sexuality with Health Workers. The model adjusted for Social Support, Everyday Discrimination, and Sociodemographics.

MAIN OUTCOME MEASURE

Engagement in HIV Prevention comprised an ad hoc measure of (i) lifetime exposure to a behavioral intervention, (ii) current adherence to biomedical intervention, and (iii) consistent use of a prevention strategy during recent penile-anal intercourse.

RESULTS

In the final model, anal sex stigma was associated with less engagement (β = -0.22, P < .001), mediated by participants' comfort talking about anal sex practices with health workers (β = -0.52; β = 0.44; both P < .001), adjusting for covariates (R2 = 67%; χ2/df = 2.98, root mean square error of approximation = 0.040, comparative fit index = 0.99 and Tucker-Lewis index = 0.99). Sex-related concerns partially mediated the association between stigma and comfort (β = 0.55; β = 0.14, both P < .001). Modification indices also supported total effects of social support on increased comfort discussing anal sex (β = 0.35, P < .001) and, to a lesser degree, on decreased sex-related concerns (β = -0.10; P < .001).

CLINICAL IMPLICATIONS

Higher stigma toward anal sexuality is associated with less engagement in HIV prevention, largely due to discomfort discussing anal sex practices with health workers.

STRENGTH & LIMITATIONS

Adjustment for mediation in a cross-sectional design cannot establish temporal causality. Self-report is vulnerable to social desirability and recall bias. Online samples may not represent cisgender MSM in general. However, findings place HIV- and health-related behaviors within a social and relational context and may suggest points for intervention in health-care settings.

CONCLUSION

Providers' willingness to engage in discussion about anal sexuality, for example, by responding to questions related to sexual well-being, may function as social support and thereby bolster comfort and improve engagement in HIV prevention.

Interface of Internalized Homophobia and Community Connectedness on Frequency of Doctor's Visits for Rural and Urban MSM in Oklahoma

PURPOSE

Men who have sex with men (MSM) face persistent risk of stigma, with past studies showing unequal treatments of MSM in health care settings. Contextual factors, such as internalized homophobia and connectedness to one's community, have shown to serve as a barrier or facilitator (respectively) with regard to MSM's decisions to seek preventative treatment. These studies, however, predominately feature urban populations, with less consideration given to rural MSM. The current study comparatively investigates these contextual factors between rural and urban MSM to detect differences in the frequency of doctor's visits.

METHODS

A 2-by-2 (rural/urban × doctor visit yes/no) multivariate analysis of variance (MANOVA) was conducted to investigate if significant differences and/or interactions existed for internalized homophobia and community connectedness.

FINDINGS

Results show a significant interaction between rurality and doctor's visits in our sample of predominantly white, self-identified gay men. Higher levels of internalized homophobia and lower levels of community connectedness were seen in rural individuals who had visited a doctor in the past 12 months and in urban individuals who had not seen a doctor in the past 12 months.

CONCLUSIONS

Study findings have implications for future public health research and for health promotion interventions, practices, and policies for MSM in rural areas. Social exclusion reinforces the invisibility of lesbian, gay, bisexual, and transgender (LGBT) populations, particularly in rural areas. Stigma and marginalization of MSM promote structural barriers inhibiting care. Our results give evidentiary support for programs which inform the work of clinicians on mechanisms to create LGBT-inclusive practice settings.

Evaluation of Algorithms Used for PrEP Surveillance Using a Reference Population From New York City, July 2016-June 2018

OBJECTIVE

Daily tenofovir disoproxil fumarate/emtricitabine (TDF/FTC) use as HIV preexposure prophylaxis (PrEP) is monitored by identifying TDF/FTC prescriptions from pharmacy databases and applying diagnosis codes and antiretroviral data to algorithms that exclude TDF/FTC prescribed for HIV postexposure prophylaxis (PEP), HIV treatment, and hepatitis B virus (HBV) treatment. We evaluated the accuracy of 3 algorithms used by the Centers for Disease Control and Prevention (CDC), Gilead Sciences, and the New York State Department of Health (NYSDOH) using a reference population in Bronx, New York.

METHODS

We extracted diagnosis codes and data on all antiretroviral prescriptions other than TDF/FTC from an electronic health record database for persons aged ≥16 prescribed TDF/FTC during July 2016-June 2018 at Montefiore Medical Center. We reviewed medical records to classify the true indication of first TDF/FTC use as PrEP, PEP, HIV treatment, or HBV treatment. We applied each algorithm to the reference population and compared the results with the medical record review.

RESULTS

Of 2862 patients included in the analysis, 694 used PrEP, 748 used PEP, 1407 received HIV treatment, and 13 received HBV treatment. The algorithms had high specificity (range: 98.4%-99.0%), but the sensitivity of the CDC algorithm using a PEP definition of TDF/FTC prescriptions ≤30 days was lower (80.3%) than the sensitivity of the algorithms developed by Gilead Sciences (94.7%) or NYSDOH (96.1%). Defining PEP as TDF/FTC prescriptions ≤28 days improved CDC algorithm performance (sensitivity, 95.8%; specificity, 98.8%).

CONCLUSIONS

Adopting the definition of PEP as ≤28 days of TDF/FTC in the CDC algorithm should improve the accuracy of national PrEP surveillance.
