Young Transgender Women's Attitudes Toward HIV Pre-exposure Prophylaxis

Long-Acting Injectable Pre-Exposure Prophylaxis Perceptions and Preferences Among Transgender and Nonbinary Young Adults in the United States

Long-acting injectable pre-exposure prophylaxis for HIV prevention (LAI-PrEP) was approved for use in the United States in 2021, yet little is known about perceptions of LAI-PrEP among transgender and nonbinary young adults, a group that faces substantial barriers to HIV prevention. We investigated US transgender and nonbinary young adults' perceptions of and attitudes toward LAI-PrEP and how perceived advantages and disadvantages of LAI-PrEP related to the PrEP continuum of care. We conducted semi-structured interviews with 31 transgender and nonbinary young adults who reported oral PrEP use or were PrEP-eligible. We analyzed responses using both a deductive RADaR approach, to identify LAI-PrEP perceptions relevant to the PrEP continuum of care, and an inductive thematic analysis to explore key themes. In this study, all PrEP-experienced and most PrEP-naïve participants indicated an interest in LAI-PrEP, citing advantages over daily oral medication (e.g., fewer adherence challenges). Three key themes emerged: (1) Some participants linked perceived advantages of LAI-PrEP to experiences with gender-affirming care (e.g., familiarity with needles via hormone use). (2) Participants weighed trade-offs and contextual factors that influenced their LAI-PrEP preferences (e.g., interest contingent on whether location for receiving injection was geographically accessible). (3) Participants envisaged alternative delivery methods that could enhance LAI-PrEP acceptability and uptake (e.g., home injection). HIV prevention programs should incorporate the insights of transgender and nonbinary young adults to ensure that emerging HIV prevention technologies are accessible and responsive to the needs and concerns of people of all gender modalities.

Pre-exposure Prophylaxis Awareness and Use Among Transgender and Nonbinary Individuals in Canada

BACKGROUND

Transgender and nonbinary populations are disproportionately affected by HIV and face barriers to accessing HIV-related services. Pre-exposure prophylaxis (PrEP) may benefit those at risk of HIV acquisition. However, PrEP awareness and uptake, along with potential barriers and facilitators, have not been investigated among transgender and nonbinary individuals living in Canada.

SETTING

This study analyzed data from 1965 participants of the 2019 Trans PULSE Canada survey, a national convenience sampling survey of transgender and nonbinary individuals in Canada.

METHODS

Data were analyzed to estimate levels of PrEP awareness and uptake and to identify predictors of PrEP awareness among the study population. Prevalence ratios estimated from block-wise modified Poisson regression models were used to assess predictors of PrEP awareness.

RESULTS

PrEP awareness, lifetime PrEP use, and current PrEP use were estimated to be 71.0%, 2.2%, and 0.9%, respectively, among the full sample, and 82.3%, 7.3%, and 3.8% among those with indications for PrEP use. Respondents who were aged 45 years or older, transfeminine, Indigenous, living in Atlantic Canada or Quebec, and had high school education or less were significantly less likely to be aware of PrEP. Lifetime sex work, past-year HIV/STI testing, being single or in a nonmonogamous relationship, and higher levels of emotional social support were positively associated with PrEP awareness.

CONCLUSIONS

There is a need to improve PrEP awareness and particularly uptake among transgender and nonbinary individuals in Canada. This study revealed inequities in PrEP awareness within this population, which may serve as targets for future public health initiatives.

Social, economic, and physical side effects impact PrEP uptake and persistence among transgender women in Peru

INTRODUCTION

Oral pre-exposure prophylaxis (PrEP) for HIV-1 infection is over 99% effective in protecting against HIV acquisition when used consistently and appropriately. However, PrEP uptake and persistent use remains suboptimal, with a substantial gap in utilization among key populations who could most benefit from PrEP. In Latin America specifically, there is poor understanding of barriers to PrEP uptake and persistence among transgender (trans) women.

METHODS

In April-May 2018, we conducted qualitative interviews lasting 25-45 min as part of an end-of-project evaluation of TransPrEP, a pilot RCT that examined the impact of a social network-based peer support intervention on PrEP adherence among trans women in Lima, Peru. Participants in the qualitative evaluation, all adult trans women, included individuals who either (1) screened eligible to participate in the TransPrEP pilot, but opted not to enroll (n = 8), (2) enrolled, but later withdrew (n = 6), (3) were still actively enrolled at the time of interview and/or successfully completed the study (n = 16), or (4) were study staff (n = 4). Interviews were audio recorded and transcribed verbatim. Codebook development followed an immersion/crystallization approach, and coding was completed using Dedoose.

RESULTS

Evaluation participants had a mean age of 28.2 years (range 19-47). When describing experiences taking PrEP, participant narratives highlighted side effects that spanned three domains: physical side effects, such as prolonged symptoms of gastrointestinal distress or somnolence; economic challenges, including lost income due to inability to work; and social concerns, including interpersonal conflicts due to HIV-related stigma. Participants described PrEP use within a broader context of social and economic marginalization, with a focus on daily survival, and how PrEP side effects negatively contributed to these stressors. Persistence was, in some cases, supported through the intervention's educational workshops.

CONCLUSION

This research highlights the ways that physical, economic, and social side effects of PrEP can impact acceptability and persistence among trans women in Peru, amplifying and layering onto existing stressors including economic precarity. Understanding the unique experiences of trans women taking PrEP is crucial to informing tailored interventions to improve uptake and persistence.

Are Rights-Based Services Important? An Adolescent PrEP Demonstration Project in Brazil

In this study, we systematically examined the importance of human rights standards and principles for rights-based pre-exposure prophylaxis (PrEP) provision for marginalized adolescents. Nested within a demonstration study of PrEP provision to adolescent men who have sex with men, travestis, and transgender women, we carried out interviews in São Paulo, Brazil with 25 adolescents, eight health providers, and six workers involved in community-based demand creation. Analysis focused on participants' narratives about aspects of human rights within service delivery, including the availability, accessibility, acceptability, and quality of services; informed decision-making; nondiscrimination; and privacy and confidentiality. Clients and service providers highlighted the importance of availing a range of services beyond PrEP and described how community outreach and social media helped promote accessibility. Acceptability centered around clients feeling heard and respected. Health workers appreciated having time to build trusting relationships with clients to ensure quality of care and support informed decision-making. Nondiscrimination was valued by all, including using clients' chosen pronouns. Privacy and confidentiality were primary concerns for clients who were not "out" about their sexuality or PrEP use; to mitigate this, health workers sought to accommodate clients' preferred channels of communication. Rights-based PrEP services can help promote engagement and retention in PrEP services, particularly for marginalized populations.

Determinants of HIV Pre-Exposure Prophylaxis (PrEP) Retention among Transgender Women: A Sequential, Explanatory Mixed Methods Study

Transgender women (TW) face inequities in HIV and unique barriers to PrEP, an effective biomedical intervention to prevent HIV acquisition. To improve PrEP retention among TW, we examined factors related to retention using a two-phase, sequential explanatory mixed methods approach. In Phase I, we used data from a trial of 170 TW who were provided oral PrEP to examine predictors of 24-week retention. In Phase II, we conducted 15 in-depth interviews with PrEP-experienced TW and used thematic analysis to explain Phase I findings. In Phase I, more participants who were not retained at 24 weeks reported sex work engagement (18% versus 7%) and substantial/severe drug use (18% versus 8%). In Phase II, participants reported drug use as a barrier to PrEP, often in the context of sex work, and we identified two subcategories of sex work. TW engaged in "non-survival sex work" had little difficulty staying on PrEP, while those engaged in "survival sex work" struggled to stay on PrEP. In Phase I, fewer participants not retained at 24 weeks reported gender-affirming hormone therapy (GAHT) use (56% versus 71%). In Phase II, participants prioritized medical gender affirmation services over PrEP but also described the bidirectional benefits of accessing GAHT and PrEP. TW who engaged in "survival sex work" experience barriers to PrEP retention (e.g., unstable housing, drug use) and may require additional support to stay in PrEP care.

Understanding the social and structural context of oral PrEP delivery: an ethnography exploring barriers and facilitators impacting transgender women who engage in street-based sex work in Baltimore, Maryland

Transgender women who sell sex (TWSS) experience high rates of HIV acquisition. Antiretrovirals for pre-exposure prophylaxis (PrEP) represent an efficacious HIV prevention strategy. The social and structural factors affecting PrEP delivery amongst TWSS are underexplored in the literature. We conducted ethnographic research to examine how multilevel social and structural factors manifest in TWSS's lived experiences and affect PrEP delivery and use. Twenty-four transgender women were recruited from the SAPPHIRE cohort and completed interviews focused on barriers and facilitators to PrEP engagement in the context of street-based sex work. Stakeholder interviews (N = 7) were also conducted. Our findings suggest there are unique features of the risk environment that can collectively impede PrEP use among TWSS.

Health Information From Web Search Engines and Virtual Assistants About Pre-Exposure Prophylaxis for HIV Prevention in Adolescents and Young Adults: Content Analysis

BACKGROUND

Adolescents and young adults are disproportionately affected by HIV, suggesting that HIV prevention methods such as pre-exposure prophylaxis (PrEP) should focus on this group as a priority. As digital natives, youth likely turn to internet resources regarding health topics they may not feel comfortable discussing with their medical providers. To optimize informed decision-making by adolescents and young adults most impacted by HIV, the information from internet searches should be educational, accurate, and readable.

OBJECTIVE

The aims of this study were to compare the accuracy of web-based PrEP information found using web search engines and virtual assistants, and to assess the readability of the resulting information.

METHODS

Adolescent HIV prevention clinical experts developed a list of 23 prevention-related questions that were posed to search engines (Ask.com, Bing, Google, and Yahoo) and virtual assistants (Amazon Alexa, Microsoft Cortana, Google Assistant, and Apple Siri). The first three results from search engines and virtual assistant web references, as well as virtual assistant verbal responses, were recorded and coded using a six-tier scale to assess the quality of information produced. The results were also entered in a web-based tool determining readability using the Flesch-Kincaid Grade Level scale.

RESULTS

Google web search engine and Google Assistant more frequently produced PrEP information of higher quality than the other search engines and virtual assistants with scores ranging from 3.4 to 3.7 and 2.8 to 3.3, respectively. Additionally, the resulting information generally was presented in language at a seventh and 10th grade reading level according to the Flesch-Kincaid Grade Level scale.

CONCLUSIONS

Adolescents and young adults are large consumers of technology and may experience discomfort discussing their sexual health with providers. It is important that efforts are made to ensure the information they receive about HIV prevention methods, and PrEP in particular, is comprehensive, comprehensible, and widely available.

Assessing HIV Pre-exposure Prophylaxis Uptake and Retention Amongst Young Females in Gauteng Province

Although roll-out of HIV pre-exposure prophylaxis (PrEP) has been reported to have changed contexts of HIV risk in areas where it was well-implemented. The rate of its uptake and retention amongst young females has not been described in Gauteng Province. This paper aimed at assessing PrEP uptake and retention among young females in Gauteng Province. Total of young females who tested HIV across five clinics from 01/January/2017 to 31/December/2020 was 19,671 with 17,937 tested HIV negative. Of the HIV tested negative, PrEP was initiated to 1307 (7%). The analysis revealed that 27% of young females returned for their first follow up visit after PrEP initiation, while third month declined to 14%, fourth month to 11%, and fifth month to 3%, sixth month to 2% and seventh month at 1% and from the eighth month, the rate of follow up was 0%. Uptake and retention of PrEP was low among young females as measured against the total tested HIV negative.

PrEP Use and Adherence among Transgender Persons in Chicago, IL (SHIPP Study, 2014-2018, USA)

Few studies investigating daily oral preexposure prophylaxis (PrEP) focus on transgender persons. The Sustainable Health Center Implementation PrEP Pilot (SHIPP) Study included a large observational cohort of transgender persons with implications for PrEP in the United States. We examined data from SHIPP's observational cohort and its Medication Adherence Substudy (MAS) to understand adherence among transgender participants in Chicago, IL. We assessed adherence by the proportion of days covered (PDC) for PrEP medication prescriptions, self-reported interview data, and concentrations of intracellular tenofovir diphosphate (TFV-DP) in dried blood spot (DBS) samples. Between 2014 and 2018, there were 510 transgender participants, 349 (68.4%) transgender women and 152 (29.8%) transgender men. Forty-five of these participants were enrolled in the MAS, 31 (68.9%) transgender women and 9 (20.0%) transgender men. By the 3-month follow up, 100% of MAS participants who completed an interview reported taking 4 or more doses of PrEP in the previous week. At 6, 9, and 12 months, taking 4 or more doses in the past week was reported by 81.0%, 94.1%, and 83.3% of participants, respectively. Results from TFV-DP DBS indicated that fewer participants reached the same level of adherence (4 or more doses/week) at clinical visits compared to self-report and even fewer participants reached this level of adherence based on the calculated PDC. Among participants who remained on PrEP throughout the study, DBS adherence levels declined after the first three months. There remains a critical need to develop strategies to address barriers and interventions that support PrEP adherence among transgender people.

Determinants of Pre-exposure Prophylaxis (PrEP) Implementation in Transgender Populations: A Qualitative Scoping Review

We conducted a scoping review of contextual factors impeding uptake and adherence to pre-exposure prophylaxis in transgender communities as an in-depth analysis of the transgender population within a previously published systematic review. Using a machine learning screening process, title and abstract screening, and full-text review, the initial systematic review identified 353 articles for analysis. These articles were peer-reviewed, implementation-related studies of PrEP in the U.S. published after 2000. Twenty-two articles were identified in this search as transgender related. An additional eleven articles were identified through citations of these twenty-two articles, resulting in thirty-three articles in the current analysis. These thirty-three articles were qualitatively coded in NVivo using adapted constructs from the Consolidated Framework for Implementation Research as individual codes. Codes were thematically assessed. We point to barriers of implementing PrEP, including lack of intentional dissemination efforts and patience assistance, structural factors, including sex work, racism, and access to gender affirming health care, and lack of provider training. Finally, over 60% of articles lumped cisgender men who have sex with men with trans women. Such articles included sub-samples of transgender individuals that were not representative. We point to areas of growth for the field in this regard.

Barriers and Facilitators to HIV Pre-Exposure Prophylaxis Uptake, Adherence, and Persistence Among Transgender Populations in the United States: A Systematic Review

HIV pre-exposure prophylaxis (PrEP) is highly effective at preventing HIV; however, PrEP use among transgender individuals remains low. We conducted a systematic review to identify barriers and facilitators to PrEP uptake, adherence, and persistence among transgender individuals in the United States. We conducted a literature search in PubMed and CINAHL databases in March 2021 and followed PRISMA guidelines. Studies were eligible if they were published in a peer-reviewed journal and reported interest, uptake, adherence, and/or persistence of PrEP use among transgender individuals. Articles that did not disaggregate results for transgender participants were excluded. Data from included articles were coded using content analysis and narratively synthesized using a framework matrix. We screened 254 unique articles published after US Food and Drug Administration approval of PrEP, and 33 articles were included in the review. Five themes were identified in the literature, including (1) PrEP concentrations were lower among individuals taking feminizing hormones, but the difference did not appear clinically significant; (2) concerns regarding interactions between gender-affirming hormone therapy and PrEP remain a large barrier; (3) PrEP initiation may facilitate increased self-advocacy and self-acceptance; (4) lack of trust in medical institutions impacts PrEP uptake; and (5) social networks have a significant influence on PrEP knowledge, interest, and adherence. Additional research is needed involving transgender men and nonbinary persons, and efforts to improve PrEP persistence among the transgender community are needed. Training health care providers to provide inclusive and affirming care is perhaps one of the strongest areas for intervention to increase PrEP uptake and persistence.

Brief Report: Transgender Women and Preexposure Prophylaxis Care: High Preexposure Prophylaxis Adherence in a Real-World Health Care Setting in New York City

BACKGROUND

Transgender women and trans feminine individuals (TGW/TFI) are a high priority population for the provision of HIV preexposure prophylaxis (PrEP) care within the United States, but there is limited research that focuses specifically on PrEP adherence within this population.

SETTING

Observational study of patients prescribed PrEP at a community-based health center.

METHODS

We enrolled 100 TGW/TFI PrEP patients at a community health center during clinic visits. Adherence data were collected at 3 time points, using self-report surveys, patient interviews, and urine assays measuring tenofovir. Data were summarized descriptively.

RESULTS

The sample was diverse in age, race/ethnicity, and socioeconomic characteristics. Participants demonstrated strong PrEP adherence; at least 80% of the sample reported 90% or greater adherence at each time point. Concordance between self-report and urine assay was high. Among patients who reported taking PrEP within the past 48 hours, 82%-92% had detectable urine tenofovir. However, many patients reported PrEP stop periods of 4 or more days (28%-39% per time point).

CONCLUSIONS

Our data highlight TGW/TFI's capacity to adhere to daily PrEP and sustain PrEP use over time. The concordance between patient self-report and urine TFV levels suggest that providers can trust patient reports of PrEP adherence behavior and support the use of adherence conversations in clinical settings, without the need for point of care biological monitoring. Findings also underscore the importance of continued attention to drivers of PrEP stops at the patient, clinic, and systems levels and the development of strategies that support sustained PrEP use.

Addressing Explanation of Benefits as a Barrier to PrEP for Adolescents in Public Health Entities

Pre-exposure prophylaxis (PrEP) is a revolutionary medical advancement to prevent HIV infection upon exposure. However, since its introduction in 2012, PrEP largely remains inaccessible to adolescents who do not wish to disclose their PrEP usage through an explanation of benefits (EOBs) and who are covered under a parent/guardian insurance. This literature review uniquely documents the concept of insurance as a barrier to PrEP access because of EOBs and how non-governmental organizations (NGOs), including community-based organizations (CBOs), have addressed this insurance policy problem. Based on the results of this review, a new approach to resolving EOBs as a barrier to PrEP access for adolescents has the potential to be implemented at the state level across the country. The approach focuses on clarifying the definition of "endanger" under HIPAA to grant adolescents the privilege of medical disclosure as it relates to EOBs.

PrEP Use and Adherence Among Transgender Patients

This cross-sectional study used 2012 to 2019 Oregon Medicaid claims to estimate the prevalence of PrEP use and identify determinants of high adherence across transgender and cisgender men and women. Gender identity (cisgender woman/man; transgender, assigned female sex at birth [AFAB]; transgender, assigned male sex at birth [AMAB]) was based on medical history and enrollment records. Proportion of days covered ≥ 0.80 was considered high adherence to PrEP. The association between gender identity and PrEP uptake or high adherence was estimated using multivariable logistic regression. 1555 PrEP users, including 171 (11.0%) cis women, 1171 (75.3%) cis men, 67 (4.3%) AFAB, and 146 (9.4%) AMAB individuals, were included. The probability of PrEP use per 10,000 people was highest in transgender groups (AMAB 546.8, 95% CI 462.4-631.3; AFAB 226.5, 95% CI 173.4-279.6), followed by cisgender men (20.6, 95% CI 19.4, 21.8) and women (2.6, 95% CI 2.2, 3.0). High adherence was significantly lower in AMAB recipients (72.6%) than cisgender women (86.0%) and cisgender men (82.2%). Among the 279 PrEP users with female on their enrollment record, 76 (27.2%) were AMAB, while among the 1276 PrEP users with male on their enrollment record, 35 (2.7%) were AFAB. This demonstrates the importance of surveillance methods that take gender identity into account in addition to sex assigned at birth. There were significant differences in PrEP use and adherence by gender identity. PrEP surveillance, outreach, and prescribing practices must consider gender identity-unique risk factors.

Increasing awareness of HIV pre-exposure prophylaxis (PrEP) and willingness to use HIV PrEP among men who have sex with men: a systematic review and meta-analysis of global data

Introduction

Integrated knowledge regarding pre‐exposure prophylaxis (PrEP) awareness and willingness to use PrEP can be useful for HIV prevention in high incidence groups. This review summarizes the awareness of PrEP and willingness to use PrEP among men who have sex with men (MSM).

Methods

Online electronic databases were searched before 31 August 2021. A meta‐analysis was conducted to pool studies analysing PrEP awareness and willingness to use PrEP. LOESS regression and linear regression were applied to fit the trends over time for the proportion of MSM aware of PrEP and willing to use PrEP. Dose–response meta‐analysis (DRMA) was conducted by a restricted cubic spline model to explore the relationship between willingness to use PrEP and selected factors.

Results and Discussion

A total of 156 articles involving 228,403 MSM were included. The pooled proportions of MSM aware of PrEP and willing to use PrEP were 50.0 (95% CI: 44.8–55.2) and 58.6% (95% CI: 54.8–62.4), respectively. PrEP awareness varied among countries with different economic status and different WHO regions, among different publication and research years, PrEP types and support policies. PrEP willingness differed among countries with different economic status and groups with different risks of HIV. The awareness of PrEP increased from 2007 to 2019 with a slope of 0.040260 (p<0.0001), while the proportion of MSM willing to use PrEP decreased from 2007 to 2014 (slope = –0.03647, p = 0.00390) but increased after 2014 (slope = 0.04187, p = 0.03895). The main facilitators of willingness to use PrEP were PrEP awareness, condomless sexual behaviours, high perceived risk of HIV infection and influence of social network. The main barriers were doubts about the efficacy and side effects of PrEP. DRMA results indicated that MSM with more sexual partners and lower level of education were more willing to use PrEP. No publication bias was observed.

Conclusions

The proportions of PrEP awareness and willingness to use PrEP among MSM have increased since 2014, although the awareness was low and the willingness was moderate. Improving awareness of PrEP through increasing access to PrEP‐related health education and enhancing risk perceptions of HIV infection could have positive effects on the willingness to use PrEP among MSM.

Perceptions and Practicalities Influencing Pre-exposure Prophylaxis Adherence Among Men Who Have Sex with Men in England

PrEP is highly effective for HIV prevention but requires adequate adherence. In this paper we use the perceptions and practicalities approach (PAPA) to identify factors that influenced PrEP adherence using qualitative data from the PROUD study. From February 2014 to January 2016, we interviewed 41 gay, bisexual and other men-who-have-sex-with-men and one trans woman who were enrolled in the study. We purposively recruited participants for interview based on trial arm allocation, adherence and sexual risk behaviours. The interviews were conducted in English, audio-recorded, transcribed, coded and analysed using framework analysis. Participants in general were highly motivated to use and adhere to PrEP, and this was linked to strong perceptions of personal necessity for PrEP as they felt at risk of HIV and viewed PrEP as highly effective. On the other hand, concerns about side effects and HIV resistance did inhibit PrEP initiation and adherence although this was uncommon. Practical factors such as daily routine, existing habitual pill-taking and pill storage impacted adherence. Drug and alcohol use rarely caused participants to miss doses. These findings indicate that using the principals of PAPA to unpick influencers of PrEP use, could help tailor adherence support in PrEP programmes.

HIV PrEP implementation: A multi-level systems approach

PURPOSE

CO-PrIDE was a three-year Pre-Exposure Prophylaxis (PrEP) demonstration project to increase access to PrEP for men who have sex with men and transgender people in the Denver/Aurora Metropolitan Statistical Area. CO-PrIDE implemented a multi-level framework featuring collaboration between health systems and community organizations to link clients to PrEP prescribers and provide support services intended to help clients overcome socioeconomic barriers to PrEP uptake. These services included payment assistance, insurance navigation, and healthcare navigation. CO-PrIDE implemented a participatory mixed-methods evaluation to understand the services associated with PrEP uptake.

RESULTS

From January 2016 to December 2018, navigators screened 10,129 clients for PrEP and offered supportive services. The results indicated that clients who received payment assistance were more likely to accept a PrEP prescription (aPR = 3.52, p < .0001). Additionally, clients were more likely to receive a PrEP prescription through a co-located health system model, meaning the clinical provider is located with the PrEP Navigator (aPR = 3.78, p < .001).

CONCLUSIONS

The primary factors associated with increased PrEP uptake included co-location of navigation and clinical PrEP services and providing navigation to payment assistance programs. The evaluation results suggest that a multi-level framework that includes diverse support services is needed to implement a sustainable PrEP program.

Socio-behavioral factors related to PrEP non-adherence among gay male PrEP users living in California and New York: A behavioral theory informed approach

One effective preventative measure to reduce the number of new HIV infections is through the uptake of daily oral HIV pre-exposure prophylaxis (PrEP). Although previous clinical trials have proven the effectiveness of on-demand PrEP uptake, daily PrEP uptake is the most popular prevention method among PrEP users and is still recommended by most healthcare professionals and organizations. Informed by the integrative model of behavioral prediction, the current study examined the socio-behavioral factors associated with PrEP non-adherence. The present study conducted a cross-sectional survey of 210 gay male daily PrEP users living in California and New York. The results showed more than two-thirds of the sample indicated that they had skipped taking PrEP within the last 30 days, averaging around four to five missed doses. General attitudes toward desirable and undesirable outcomes, perceived behavioral control, and social-level barriers were associated with daily PrEP uptake non-adherence. The findings highlight providers' role in PrEP adherence and the importance of habit-forming, which can be enhanced by cost-effective strategies and technological innovations.

Human Immunodeficiency Virus Preexposure Prophylaxis in Adolescents and Young Adults

Human immunodeficiency virus (HIV) prevention holds the promise of decreasing the burden of HIV infections worldwide. Access to HIV prevention services, including preexposure prophylaxis (PrEP), is a key strategy in reducing HIV transmission, but it continues to be underused. PrEP, a once-daily medication for HIV prevention, is approved for adolescents. A pediatrician's role is critical in identifying and increasing access for adolescents and young adults to PrEP services and reducing HIV acquisition in youth.

Expanding the Pie-Differentiated PrEP Delivery Models to Improve PrEP Uptake in the San Francisco Bay Area

BACKGROUND

Pre-exposure prophylaxis (PrEP) uptake among trans people to date has been low. Recommendations implemented in San Francisco to offer PrEP with feminizing hormones have not led to improvement of PrEP uptake in trans communities. New delivery models may be needed. The aim of this study was to examine whether a PrEP-only clinic was more likely to serve trans people at highest risk of HIV than trans-affirming primary care clinics.

METHODS

Participants were recruited between 2017 and 2019 as part of a PrEP demonstration project in the San Francisco Bay Area. Survey data including sociodemographics, HIV-related risk behavior, barriers to PrEP, and self-reported PrEP adherence were collected at baseline, 3 months, and 6 months for all participants. Bivariable Poisson regression models were used to examine differences between participants in the primary care clinics and PrEP-only clinic delivered to participants.

RESULTS

Baseline survey data were collected from 153 participants. Those with a higher number of sexual partners were significantly more likely to use the PrEP-only clinic rather than the primary care clinics. Participants with higher perceived HIV risk and those who engaged in sex work were also more likely to use the PrEP-only clinic compared with the primary care clinic. Medical mistrust was higher at baseline among participants of the PrEP-only clinic. PrEP adherence was not significantly different by delivery model. Few participants identified PrEP barriers, such as interactions with feminizing hormones, to be determinants of PrEP uptake.

CONCLUSIONS

A PrEP-only delivery model could improve PrEP uptake and may better meet the needs of trans people who could most benefit from PrEP.

Experiences and Perspectives of Transgender Youths in Accessing Health Care: A Systematic Review

IMPORTANCE

Transgender and nonbinary youths have a higher incidence of a range of health conditions and may paradoxically face limited access to health care.

OBJECTIVE

To describe the perspectives and needs of transgender youths in accessing health care.

EVIDENCE REVIEW

MEDLINE, Embase, PsycInfo, and the Cumulative Index to Nursing and Allied Health Literature were searched from inception to January 2021. Qualitative studies of transgender youths' perspectives on accessing health care were selected. Results from primary studies were extracted. Data were analyzed using thematic synthesis.

FINDINGS

Ninety-one studies involving 884 participants aged 9 to 24 years across 17 countries were included. We identified 6 themes: experiencing pervasive stigma and discrimination in health care, feeling vulnerable and uncertain in decision-making, traversing risks to overcome systemic barriers to transitioning, internalizing intense fear of consequences, experiencing prejudice undermining help-seeking efforts, and experiencing strengthened gender identity and finding allies. Each theme encapsulated multiple subthemes.

CONCLUSIONS AND RELEVANCE

This review found that transgender youths contend with feelings of gender incongruence, fear, and vulnerability in accessing health care, which are compounded by legal, economic, and social barriers. This can lead to disengagement from care and resorting to high-risk and unsafe interventions. Improving access to gender-affirming care services with a cultural humility lens and addressing sociolegal stressors may improve outcomes in transgender and nonbinary youths.

Community Belonging and Attitudes Towards HIV Pre-Exposure Prophylaxis (PrEP) Among Transgender Women

For transgender (trans) women, community belonging may play an important role in shaping perceptions of HIV Pre-exposure Prophylaxis (PrEP). A cluster analysis was performed using data obtained from a survey administered to 128 trans women residing in Philadelphia, PA and the San Francisco Bay area, CA. Six items assessing feelings of community belongingness among trans women produced three distinct clusters. Associations were examined between cluster membership and perceptual items including beliefs about PrEP, experiences with healthcare, patient self-advocacy, and perceived trusted sources for PrEP information. Clusters were demographically comparable apart from age. There were significant differences noted between trust in various communication channels and perceptions of PrEP; the least community-connected cluster had less trust and more negative perceptions of PrEP. Analyses suggest that psychographic differences exist based on perceived community belongingness in this population, and this in turn may be consequential in determining how information about PrEP is communicated and diffused to trans women for whom PrEP may be indicated.

How Has HIV Pre-Exposure Prophylaxis (PrEP) Changed Sex? A Review of Research in a New Era of Bio-behavioral HIV Prevention

In 2012, the U.S. FDA approved the first drug for use as HIV Pre-Exposure Prophylaxis (PrEP), which is nearly 99% effective when taken as prescribed. Although the manifest function of PrEP is to prevent HIV infection in the event of exposure, the drug has also had a significant impact on various facets of sexuality. In this review, we focus on research that emerged in the near decade since PrEP's approval, with a specific focus on the ways in which different elements of sex and sexuality have been impacted by gay, bisexual, and other men who have sex with men (GBMSM), cisgender women, and transgender individuals. We highlight evidence showing how PrEP has enhanced sexual self-esteem, improved sexual pleasure, reduced sexual anxiety, and has increased sexual agency for those taking it. For many, PrEP also serves as a gateway to improve routine health and increase sexual health-care utilization. Additionally, we review the question of whether PrEP is associated with increased sexual risk taking (i.e. risk compensation), and note that, although some data are mixed, PrEP is not intended as an intervention to reduce condomless anal sex or STIs: it aims to prevent HIV. Finally, our review highlights that, although the volume of research on PrEP among GBMSM is robust, it is underdeveloped for cisgender women and transgender populations and insufficient for inclusion in such a review for cisgender heterosexual men was. PrEP research with these populations is an important direction for future research. Finally, from 2012 to 2019, a single PrEP formulation and delivery method was FDA approved (oral emtricitabine/tenofovir disoproxil fumarate). As additional drug formulations (ie.g., emtricitabine/tenofovir alafenamide) and delivery methods (e.g., microbiocides, vaginal ring, injectable) come to market, it will be important to examine how these, too, impact the spectrum of sexuality.

Usability Evaluation of the mLab App for Improving Home HIV Testing Behaviors in Youth at Risk of HIV Infection

Improving access to HIV testing among youth at high risk is essential for reaching those who are most at risk for HIV and least likely to access health care services. This study evaluates the usability of mLab, an app with image-processing feature that analyzes photos of OraQuick HIV self-tests and provides real-time, personalized feedback. mLab includes HIV prevention information, testing reminders, and instructions. It was developed through iterative feedback with a youth advisory board (N = 8). The final design underwent heuristic (N = 5) and end-user testing (N = 20). Experts rated mLab following Nielsen's heuristic checklist. End-users used the Health Information Technology Usability Evaluation Scale. While there were some usability problems, overall study participants found mLab useful and user-friendly. This study provides important insights into using a mobile app with imaging for interpreting HIV test results with the goal of improving HIV testing and prevention in populations at high risk.

Young Transgender Women of Color: Homelessness, Poverty, Childhood Sexual Abuse and Implications for HIV Care

This study describes a sample of HIV+ young transgender women of color aged 18-24 and their experience with homelessness as part of a demonstration project of engagement and retention in HIV medical care funded by Health Resources and Services Administration. The study engaged transgender women of color in HIV care in nine sites across the US between 2012 and 2017. This analysis describes and compares transwomen who had been homeless in the last 6 months to those not homeless. We hypothesized that homelessness would compete with HIV care, food, shelter, and be associated with poverty. Variable domains included sociodemographic, mental health and substance use, HIV care, sexual risk behavior, social support from transgender and other friends, and childhood sexual abuse. There were 102 youth enrolled, 77 (75.5%) who had been homeless, and 25 (24.5%) who had not been homeless. Bivariate analyses showed that low income, sex work as source of income, inability to afford food, lack of viral load (VL) suppression, childhood sexual abuse, lower levels of social support, and higher levels of depression were associated with homelessness. A logistic regression model showed that being unable to afford food (AOR = 9.24, 95% CI 2.13-40.16), lack of VL suppression in last 6 months (AOR = 0.10, 95% CI .02-.57), and lack of transgender friend support (AOR = 0.09, 95% CI .02-.53) was associated with homelessness. Programs that place basic needs first-food and shelter-may be able to engage and assist young transgender women of color with HIV to survive and live healthier lives.

Policy considerations for scaling up access to HIV pre-exposure prophylaxis for adolescent girls and young women: Examples from Kenya, South Africa, and Uganda

Adolescent girls and young women (aged 15-24 years; AGYW) continue to carry a disproportionate burden of HIV in sub-Saharan Africa. Pre-exposure prophylaxis (PrEP) helps reduce the risk of acquiring HIV for persons at substantial risk, including AGYW. As countries plan for the rollout of PrEP across sub-Saharan Africa, PrEP policies and programs could address the unique needs of AGYW. The purpose of this analysis was to identify policy considerations to improve AGYW access to PrEP. After reviewing the literature, we identified 13 policy considerations that policymakers and stakeholders could evaluate when developing or reviewing PrEP-related policies. We sorted these considerations into five categories, which together comprise an AGYW Access to PrEP Framework: AGYW-friendly delivery systems, clinical eligibility and adherence support, legal barriers and facilitators, affordability, and community and AGYW outreach. We also reviewed policies in three countries (Kenya, South Africa, and Uganda) to explore how PrEP-related policies addressed these considerations. Some of these policies addressed some of the 13 policy considerations, but none of the policies directly addressed the unique needs of AGYW for accessing PrEP. To improve access to PrEP for AGYW, country policies could include specific components that address these 13 considerations. To reach AGYW effectively, each country could use the 13 considerations we have identified to analyze current policies to identify existing programmatic barriers to AGYW accessing HIV services and address these barriers in PrEP-related policies.

Awareness and Knowledge of Pre-exposure Prophylaxis Among Sexual and Gender Minority Adolescents Assigned Male at Birth in the United States

Sexual and gender minority (SGM) adolescents assigned male at birth are at increased risk for HIV infection. Pre-exposure prophylaxis (PrEP) is a daily pill taken to prevent HIV, which the United States Food and Drug Administration approved for minors under age 18 years weighing at least 77.5 lb in 2018. A lack of awareness and knowledge of PrEP are barriers to uptake among adults and adolescents, but SGM adolescents' awareness and knowledge about PrEP remain underexplored and no studies have assessed SGM adolescents' informational needs. We collected data on 59 SGM adolescents' (ages 14-18 years) awareness, knowledge, and questions about PrEP in an online survey and six online focus groups. Although a majority of SGM adolescents (83.1%) were aware of PrEP before the study, many wanted more information about side effects and how to navigate potential barriers to PrEP initiation. Findings can inform public health efforts to promote PrEP knowledge and uptake among SGM adolescents.

Pre-Exposure Prophylaxis (PrEP) for HIV Infection in Cisgender and Transgender Women in the U.S.: A Narrative Review of the Literature

Using a socioecological approach, this review describes the peer-reviewed literature on oral pre-exposure prophylaxis (PrEP) among both cisgender (cis women) and transgender women (trans women) in the U.S. A search of the PubMed database and HIV-related conference abstracts generated over 2,200 articles and abstracts. Of these, 103 fulfilled review inclusion criteria. Most of the existing research presents findings on individual-level factors associated with PrEP use such as willingness and perceived barriers. There was far less investigation of factors related to PrEP at more distal ecological levels. Though trans women are at greater risk of HIV infection than cisgender women, less is known about this population group with respect to PrEP despite their inclusion in many major clinical trials. Further, the literature is characterized by a persistent conflation of sex and gender which makes it difficult to accurately assess the reviewed research on HIV prevention and PrEP apart from risk group. Informed by these findings, we highlight specific opportunities to improve access to PrEP and reduce socioecological barriers to PrEP care engagement for cisgender and transgender women.

PrEP Uptake and Discontinuation Among a U.S. National Sample of Transgender Men and Women

Pre-exposure prophylaxis (PrEP) has revolutionized HIV prevention efforts by effectively preventing the sexual transmission of HIV infection. Few studies have examined PrEP uptake and discontinuation among transgender individuals who are underserved in HIV prevention efforts. An online U.S. nationwide survey screened 294 HIV-negative transgender people for participation in a larger cohort study. We analyzed associations between demographic characteristics and PrEP use and discontinuation. We conducted thematic analyses of open-ended responses to identify reasons for PrEP discontinuation. Fifty-one participants (17.4%) reported ever receiving a PrEP prescription. Transgender men reported higher PrEP use than transgender women (χ2 = 18.06; p < 0.0001). PrEP discontinuation was reported by 49.0% of individuals who reported PrEP use. Reasons for PrEP discontinuation were related to side effects, insurance coverage, relationship status, and access to providers. HIV prevention efforts to increase PrEP should include mechanisms for PrEP uptake and re-initiation among transgender individuals.

Mental Health, Social Influences, and HIV Pre-exposure Prophylaxis (PrEP) Utilization Among Men and Transgender Individuals Screening for HIV Prevention Trials

The effects of mental health comorbidities and social support on the HIV pre-exposure prophylaxis (PrEP) care continuum are unknown. We conducted a cross-sectional study of men and transgender individuals, ≥ 18 years-old, with ≥ 2 male or transgender partners, or recent condomless anal intercourse. Surveys assessed demographics, mental health treatment, depressive symptomatology, social support, and PrEP-related social contacts. Logistic regression assessed associations between these factors and PrEP uptake and persistence. Participants (n = 247) were 89% cis-male and 46% African-American. Median age was 27 (IQR:23-33). Thirty-seven percent had ever used PrEP, of whom 18% discontinued use. High depressive symptomology was identified in 11% and 9% were receiving mental health treatment. There were no significant associations between depressive symptoms or mental health treatment on the odds of PrEP uptake or discontinuation. Each additional PrEP contact conferred a greater odds of uptake (aOR:1.24, 95% CI: 1.09-1.42). Network-level targets may produce fruitful interventions to increase PrEP uptake.

Barriers and motivators to pre-exposure prophylaxis uptake among Black and Latina transgender women in Los Angeles: perspectives of current PrEP users

The purpose of this qualitative study was to identify barriers and motivators to PrEP uptake from the perspective of Black and Latina transgender women (TW) who are currently using PrEP to suggest intervention and outreach activities to increase PrEP uptake in this population. The Information-Motivation-Behavioral Skills Model guided the development of the semi-structured interview guide. A thematic analysis approach was used to analyze the data. Perceived barriers to PrEP uptake included structural and logistic barriers, language and cultural barriers to medical engagement, lack of transgender competent or gender-affirming care, and prioritizing hormone therapy over the use of PrEP. To increase PrEP uptake among BLTW, participants recommended disseminating PrEP information through a variety of methods, highlighting relationship and sexual health benefits of using PrEP, and developing effective patient-provider communication. Our findings highlight several ways to promote PrEP among BLTW. PrEP promotion should be integrated into gender-affirming care and supported by peer education and navigation services that reach BLTW in both clinic and community settings.

The ongoing HIV epidemic in American youth: challenges and opportunities

The incidence of human immunodeficiency virus (HIV) infection has been decreasing in the United States overall, except among youth, and in particular among Black and Latinx young men who have sex with men (MSM). In this review we summarize key drivers of the HIV epidemic among youth, as well as novel interventions geared specifically towards combating the epidemic among high-risk populations. Many factors driving the HIV epidemic among youth are related to systemic inequities, including lack of access to healthcare, inadequate education, and internalized and experience homophobia and racism. Developmentally, youth may feel that they are invulnerable and be willing to engage in risks. Moreover, HIV is often invisible for youth given advances in treatment and community stigma, limiting open discussion of risk and new preventive modalities. Outcomes from the HIV treatment cascade suggest that youth are less likely to be aware of their HIV infection status, less likely to link to and be engaged in care, and less likely to be virologically suppressed than older MSM and other populations of people living with HIV. Importantly, pre-exposure prophylaxis (PrEP) has been shown to be an effective tool for prevention of HIV infection that also appears to have disproportionately poor uptake among youth. Barriers to PrEP utilization appear to be quite heterogeneous, and include patient-, provider-, and structural-level barriers. Interventions important in improving HIV prevention will thus have to be multipronged and developed for culturally diverse populations. Cognitive behavioral therapy-based interventions are promising strategies as they are able to address a diverse array of barriers. New formulations of PrEP will also likely be instrumental in improving adherence. Since youth spend considerable amounts of time accessing digital media, the deployment of apps and other mobile phone-based interfaces offer unique opportunities to increase education and to facilitate HIV prevention for at risk youth. Multiple studies are underway to better inform the optimal delivery of treatment and prevention services for this complex and diverse population, and include novel sociobiological interventions and new modes of medication delivery that may lend themselves to overcoming obstacles specific to youth.

A Tale of Two Cities: Exploring the Role of Race/Ethnicity and Geographic Setting on PrEP Use Among Adolescent Cisgender MSM

Although pre-exposure prophylaxis (PrEP) could substantially reduce the risk of HIV acquisition among adolescent cisgender men who have sex with men (cisMSM), various barriers faced by people of color, particularly within the southern region of the U.S., may lead to racial disparities in the utilization of PrEP. Few studies, however, have explored racial/ethnic differences in PrEP use by geographic setting among adolescent cisMSM. We conducted a cross-sectional analysis examining racial disparities in PrEP use among cisMSM ages 15-24 years in New Orleans, Louisiana, and Los Angeles, California recruited between May, 2017 and September, 2019. The odds of PrEP use among AA adolescents were considerably lower than White adolescents in New Orleans (OR (95% CI): 0.24 (0.10, 0.53)), although we did not find evidence of differences in Los Angeles. Our findings underscore the need for targeted interventions to promote PrEP use among adolescent MSM, particularly among AA adolescent cisMSM living in the southern region of U.S.

Management and Prevention of HIV Among Transgender Adults

Transgender individuals face discrimination, violence, social exclusion, and other social, political, and economic factors that result in increased vulnerability to HIV. Rates of viral suppression and uptake of preexposure prophylaxis are lower among transgender individuals than the general population. HIV clinics can help improve these rates by promoting inclusivity and tailoring care to the specific needs of transgender patients. This article summarizes an International Antiviral Society-USA (IAS-USA) webinar presented by Asa E. Radix, MD, PhD, MPH, on August 18, 2020. This webinar is available on demand at https://www.iasusa.org/courses/on-demand-webinar-2020-radix/.

Barriers and Facilitators to PrEP Initiation and Adherence Among Transgender and Gender Non-Binary Individuals in Southern California

While transgender and gender non-binary (trans/nb) individuals are disproportionately affected by HIV, pre-exposure prophylaxis (PrEP) uptake remains low in this underserved population. We conducted four focus groups with 37 trans/nb individuals in San Diego and Los Angeles to assess barriers and facilitators of PrEP usage. Transcripts were coded for qualitative themes. Although overall PrEP awareness was high, participants reported limited knowledge and misinformation about PrEP. Barriers to PrEP use included: structural access (e.g., discrimination from health care providers, lack of trans-inclusive services, financial barriers), mental health struggles limiting ability to access PrEP, and concerns about potential side effects, drug-drug interactions with hormone therapy, and lack of other STI protection. Facilitators of PrEP usage included: increased PrEP availability, prior experience taking daily medications, and motivation to have active and healthy lives without fear of contracting HIV. Addressing both structural and psychosocial/behavioral factors in trans-affirming health care environments is crucial to designing inclusive, effective PrEP interventions.

HIV Preexposure Prophylaxis Among Adolescents in the US: A Review

IMPORTANCE

Many adolescents and young adults in the US are disproportionately affected by HIV. Several others who are uninfected are at risk and in need of effective preventive strategies. The uptake rate of preexposure prophylaxis (PrEP) for HIV prevention has remained low among US adolescents. This review assesses the current status of PrEP uptake among at-risk adolescents aged 13 to 19 years and recommendations for improving PrEP access, uptake, and future needed directions, including specific recommendations for health care professionals.

OBSERVATIONS

Of the 37 377 new HIV diagnoses made in 2018, 7734 diagnoses (21%) occurred in adolescents and young adults aged 12 to 24 years; of these, 1707 diagnoses (22%) occurred in adolescents aged 13 to 19 years. The greatest burden of HIV is found among young African American men who have sex with men, accounting for two-thirds of all HIV infections in adolescents and young adults. Preexposure prophylaxis awareness and engagement are lowest in adolescents with the greatest risk for HIV. Adolescent primary care clinicians and specialists do not routinely offer HIV testing as recommended by the Centers for Disease Control and Prevention or routinely assess sexual risk exposures of patients through sexual history taking. Clinicians' decision to prescribe PrEP for adolescents is often guided by their perceptions of the patient's HIV risk and their knowledge and acceptance of PrEP guidelines. State laws on consent, confidentiality, and the rights of the adolescent to independently access PrEP outside of parental influence differ across jurisdictions, often limiting access and uptake.

CONCLUSIONS AND RELEVANCE

Use of PrEP in adolescents at risk for HIV is an important component of HIV prevention. Optimizing uptake includes improving clinicians' knowledge about HIV risk and prevention strategies, enhancing sexual history taking and risk assessment through training and retraining, and improving PrEP knowledge and acceptance of prescribing among clinicians. Leveraging the ubiquity of social media, encouraging family support, and performing research aimed at finding lifestyle-congruent formulations can help mitigate HIV transmission in adolescents at greatest risk for HIV.

Pathopolitics: Pathologies and Biopolitics of PrEP

This paper unveils the pathologies that are produced and sustained by the pharmaceutical industry, specifically by Gilead Sciences, Inc. Broadly defined, pathopolitics is the politics of treating and/or reproducing pathologies. This paper examines pathopolitics in the context of PrEP, or pre-exposure prophylaxis, an antiretroviral medicine that prevents HIV transmission. Although Gilead promises to prevent a pathology through PrEP, it reproduces social and biological pathologies by exposing certain people to higher risks of infections and diseases, thus epitomizing the operating logic of the pharmaceutical industry: that life is protected only insofar as it offers surplus economic and social value. This essay raises three fundamental sets of questions: (1) What are the techniques and mechanics of pathopolitics? (2) How does the pharmaceutical industry produce and exploit surplus value? (3) What is the nature of the relationship between the pharmaceutical citizenship and pathopolitics?

Strategies for engaging transgender populations in HIV prevention and care

PURPOSE OF REVIEW

Transgender (trans) populations are heavily impacted by HIV, yet face structural, social, and individual barriers to engagement in HIV prevention and care. In this review, we summarize the data on barriers and facilitators and discuss evidence-informed strategies to facilitate access to and engagement in HIV prevention and care by trans communities.

RECENT FINDINGS

Intersectional stigma and discrimination at structural, community, individual levels present substantial impediments to HIV prevention and optimal care. Access to gender-affirming health care is a priority for trans communities. Where trans communities are highly networked, these networks may provide a strong infrastructure for disseminating HIV innovations and reaching individuals who are not engaged in HIV services. Efforts to engage trans people in HIV prevention and care must address stigma, provide gender-affirming services, and build on community strengths and priorities to ensure trans populations achieve maximum benefit from advances in HIV prevention and care.

SUMMARY

Combination approaches that respond to the complex drivers of HIV in trans communities represent promising strategies for engaging trans people and their partners in HIV prevention and care.

Characterizing PrEP Awareness and Interest Among Filipina Transgender Women

Pre-exposure prophylaxis (PrEP) can efficaciously avert HIV acquisition for individuals at risk, including transgender individuals (trans) in the Philippines. We conducted multivariate logistic regression procedures in an online sample of Filipina trans women (n = 139) to examine associations of PrEP awareness. In this sample, 53% of Filipina trans women were unaware of PrEP, but almost all (93%) expressed interest in taking PrEP once learning about it. Greater odds of PrEP awareness was associated with discussion of HIV services with their health care providers, higher HIV knowledge, and discussion of PrEP among trans friends. Lower odds of PrEP awareness was associated with reporting being currently unemployed. The findings underscore a subset of trans women who might be early adopters of PrEP, and highlight PrEP inequities among trans women most marginalized, including those who are unemployed and have engaged in sex work.

Barriers and motivators to pre-exposure prophylaxis uptake among Black and Latina transgender women in Los Angeles: perspectives of current PrEP users

The purpose of this qualitative study was to identify barriers and motivators to PrEP uptake from the perspective of Black and Latina transgender women (TW) who are currently using PrEP to suggest intervention and outreach activities to increase PrEP uptake in this population. The Information-Motivation-Behavioral Skills Model guided the development of the semi-structured interview guide. A thematic analysis approach was used to analyze the data. Perceived barriers to PrEP uptake included structural and logistic barriers, language and cultural barriers to medical engagement, lack of transgender competent or gender-affirming care, and prioritizing hormone therapy over the use of PrEP. To increase PrEP uptake among BLTW, participants recommended disseminating PrEP information through a variety of methods, highlighting relationship and sexual health benefits of using PrEP, and developing effective patient-provider communication. Our findings highlight several ways to promote PrEP among BLTW. PrEP promotion should be integrated into gender-affirming care and supported by peer education and navigation services that reach BLTW in both clinic and community settings.

Use of HIV Self-Testing Kits to Screen Clients Among Transgender Female Sex Workers in New York and Puerto Rico

Transgender female sex workers (TFSW) are highly affected by HIV, with a global prevalence of 27%. HIV self-testing (HIVST) to screen sexual partners has helped men who have sex with men and female sex workers make informed sexual decisions and avoid HIV exposure. This is the first report on TFSW's experiences screening clients using HIVST. Ten TFSW were each given ten HIVST kits and returned after 3 months to complete an online questionnaire and undergo an interview. Eight of them reported using HIVST with potential partners. Among fifty potential partners who were asked in person to test, 42 (84%) were clients. Thirty-four out of fifty (68%) accepted and 16 (32%) refused. Very few violent incidents occurred, and participants felt empowered by offering HIVST to others. Nevertheless, HIVST market cost was prohibitive for future use. HIVST use with clients could be feasible for TFSW if the cost were lowered or subsidized.

Acceptability of HIV Pre-Exposure Prophylaxis Among Transgender Women in India: A Qualitative Investigation

Despite high HIV prevalence among transgender women (TGW) in India, there is limited exploration of pre-exposure prophylaxis (PrEP) acceptability. With PrEP licensure pending, we conducted six focus group discussions (FGDs) with diverse TGW (n = 36), and eight key informant interviews with community leaders and physicians, in Mumbai and Chennai. Data were explored using framework analysis guided by the Theoretical Framework of Acceptability. FGD participants' mean age was 26.1 years (SD = 4.8); two-thirds engaged in sex work. TGW reported low PrEP awareness, with moderate acceptability once PrEP was explained. Population-specific facilitators of PrEP acceptability included its perceived effectiveness in the context of challenges to condom use in serodiscordant relationships and forced sex encounters. PrEP was considered especially appropriate for TGW sex workers; however, barriers were anticipated in the context of hierarchical hijra (indigenous trans identity) kinship networks and gurus' (masters) potential negative reactions to PrEP use by their chelas (disciples). Positive attitudes toward high efficacy and potential covert use were tempered by TGW's concerns about high costs and adherence challenges living with parents or primary partners, and TGW sex workers' unpredictable schedules. Anticipated interactions with feminizing hormones, visible side effects, and PrEP-related stigma within TGW communities emerged as opportunity costs. PrEP implementation for TGW in India should promote comprehensive information on side effects and potential interactions with feminizing hormones, provide free or subsidized PrEP, and highlight the advantages of added protection in sex work and forced sexual encounters. Meaningful engagement with TGW kinship networks can encourage positive transgender community norms on PrEP use and mitigate multifaceted stigma.

Is Insurance a Barrier to HIV Preexposure Prophylaxis? Clarifying the Issue

Clinical trials have demonstrated that preexposure prophylaxis (PrEP) protects against HIV infection; yet, even with its approval by the Food and Drug Administration (FDA) in 2012, less than 10% of eligible users in the United States are currently taking PrEP.While there are multiple factors that influence PrEP uptake and pose barriers to PrEP implementation, here we focus on PrEP's cost in the United States, which, at the current list price of $2000 per month and with high levels of cost sharing, can leave insured users with more than $1000 in out-of-pocket costs every year. We discuss how patient deductibles, monthly premiums, copayments, and coinsurance vary widely and may increase the financial burden. Although drug payment-assistance programs have made PrEP more affordable to uninsured and underinsured users, lack of insurance is a barrier to PrEP accessibility. The FDA approved a generic version in 2017; however, that version has not been distributed to US consumers and may not be more affordable.As other countries begin implementing PrEP programs, the extent of PrEP's availability as a tool in the global fight against HIV remains to be seen.

Factors Associated with PrEP Support and Disclosure Among YMSM and Transgender Individuals Assigned Male at Birth in Chicago

Pre-exposure prophylaxis (PrEP) is one of the best biomedical HIV prevention tools available. However, uptake, particularly in communities of men who have sex with men (MSM) and transgender individuals assigned male at birth (AMAB), remains low. Further, the role of an individual's social support structure on PrEP uptake and adherence remains largely understudied. Understanding MSM and AMAB transgender individuals' perceptions of PrEP use as well as support and patterns of disclosure of (or intent to disclose) their PrEP status may offer key insights into how best to improve uptake in vulnerable communities. Further, the influence of one's social connections on other factors, such as perceptions of and conversations about PrEP deserves attention as well, as these factors may be key to improved knowledge and uptake. Therefore, we assessed perceptions of PrEP use, disclosure of or intent to disclose PrEP status, and social support and associated factors among a cohort of MSM and AMAB transgender individuals in a large Midwestern city. Results demonstrated that, among those not taking PrEP, bisexual participants and those unsure of their sexual identity were less likely to be comfortable with the idea of disclosing PrEP use were they ever to start taking it. Encouragingly however, we found that individuals who reported disclosing their PrEP status had high rates of support among friends and relatives. We also observed that knowing someone else who was on PrEP was associated with increased likelihood of discussing PrEP with one's medical provider, as was increased age. Other findings and implications for research, policy, and practice are discussed within.

Barriers and Facilitators of PrEP Adherence for Young Men and Transgender Women of Color

We aimed to discover barriers and facilitators of HIV pre-exposure prophylaxis (PrEP) adherence in young men and transgender women of color who have sex with men (YMSM/TW). Short-term and sustained adherence were measured by urine tenofovir concentration and pharmacy refills, respectively. Optimal adherence was defined as having both urine tenofovir concentration consistent with dose ingestion within 48 h and pharmacy refills consistent with ≥ 4 doses per week use. Participants completed semi-structured interviews exploring adherence barriers and facilitators. Participants (n = 31) were primarily African-American (68%), mean age 22 years (SD: 1.8), and 48% had optimal adherence. Adherence barriers included stigma, health systems inaccessibility, side effects, competing stressors, and low HIV risk perception. Facilitators included social support, health system accessibility, reminders/routines, high HIV risk perception, and personal agency. Our findings identify targets for intervention to improve PrEP adherence in these populations, including augmenting health activation and improving accuracy of HIV risk perception.

Expanding Knowledge About Implementation of Pre-exposure Prophylaxis (PrEP): A Methodological Review

Methodological limitations in PrEP implementation studies may explain why PrEP implementation is lagging. This methodological review provides a description and critique of the methods used to identify barriers to PrEP implementation in the United States (2007-18). For each selected article, we provide: (1) research questions; (2) measures; (3) design; (4) sample (size and type); and (5) theoretical orientation. Among 79 articles which identified knowledge, attitudes, and behavioral and social/structural barriers to PrEP implementation, 51 (65%) were quantitative; 25 (32%) qualitative; and 3 (4%) were mixed-methods; overall, just one-half described a conceptual approach. About two-thirds of articles were conducted with patients and one-third with healthcare providers. Our review reveals a paucity of longitudinal, mixed-methods, and ethnographic/observational research and guiding theoretical frameworks; thus, the applicability of results are limited. We recommend that interventions aimed at PrEP implementation address barriers situated at multiple ecological domains, and thus improve PrEP access, uptake, and adherence.

Underutilization of Pre-Exposure Prophylaxis Services Among Transgender and Nonbinary Youth: Findings from Project Moxie and TechStep

We use quantitative and qualitative data from two ongoing studies to describe pre-exposure prophylaxis (PrEP) awareness, willingness to use PrEP, barriers to facilitators of PrEP uptake, and PrEP use among 15- to 24-year-old transgender and gender nonbinary (TGNB) youth. Most youth were aware of PrEP, but only one participant across both studies reported current use. Uncertainty about willingness to take PrEP may be related to general (e.g., medication cost) and trans-specific (e.g., PrEP–hormone interactions) concerns. Intensified and sustained efforts are needed to engage TGNB youth along the PrEP continuum and the impact of new PrEP administration and dosing options should be examined for TGNB youth.
