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

"I'm Trusting You with My Body": A Qualitative Examination of the Role of Trust in Safer Sexual Decision-Making Among Black Women

Black women are disproportionately impacted by HIV, such that they are diagnosed at eight times the rate of White women and three times that of Latinas. Given that HIV transmission among Black women is primarily attributed to heterosexual sex, it is imperative to better understand factors that influence Black women's sexual health decision-making. Previous studies have highlighted the influence of trust on sexual decision-making; however, scant literature focuses on trust in the relationships of Black women, for whom it may differentially impact their sexual health. Nine focus groups were conducted to examine how trust affects sexual health decision-making among Black women who have sex with men (N = 56). Qualitative analyses revealed three themes that highlight how trust can influence sexual behavior: (1) Trust Buffers Risk of Physical and Emotional Harm; (2) Broken Trust Encourages Safer Sex Behavior; (3) Trust Dynamics Influence Sexual Communication Anxiety. This analysis expands on extant literature by identifying how differing forms of trust can be understood and leveraged in the context of HIV/STI prevention and sexual health for women engaging in heterosexual sex. Implications of the study indicate that concepts of trust should be addressed in interventions seeking to improve the sexual health of Black women.

Understanding sociocultural influences in sexual health promotion and HIV protection among Latinx sexually minoritized men: A qualitative study

In the United States, Latinx individuals account for 18% of the overall population, yet sexual minoritized men (SMM) within this demographic disproportionately represent 30% of new HIV diagnoses among all SMM. Despite the availability of highly effective HIV prevention strategies such as Pre- exposure Prophylaxis (PrEP), there are marked inequities in access and utilization of these strategies among Latinx SMM. Sociocultural factors and the experiences of Latinx SMM shape beliefs about sexual health promotion and influence HIV self-protective behavior (e.g., the correct and consistent use of condoms, regular engagement in HIV testing, and PrEP use) in this group. A descriptive, qualitative study, using thematic analysis, was designed to describe the sociocultural barriers and facilitators that influence sexual health promotion and HIV self-protection among Latinx SMM. A convenience sample of 15 Latinx SMM was recruited from an ongoing longitudinal study and online for individual interview, which were conducted virtually between October 2020 and October 2021. Five themes emerged from the data: 1) prevention is better than to cure; 2) cultural and religious norms create a culture of silence around sexual health; 3) lack of information and misinformation leading to self-reliance for sexual health protection; 4) growing wiser: maturity's impact on sexual health and relationships; and 5) unjust and dehumanizing sexual health care. The findings from this study highlighted that stigma and structural factors shape the opportunities of Latinx SMM to engage in sexual health promotion and HIV self-protection. These findings emphasize the need for focus on addressing structural barriers such as sexual health education, access to care, and healthcare provider bias to improve sexual health outcomes among Latinx SMM.

Non-Consensual Sex and Help-Seeking Behavior Among PrEP Users in Belgium: Findings from an Online Survey

Non-consensual sex poses a threat not only to sexual health but also to mental and physical health in general. HIV pre-exposure prophylaxis (PrEP) users might be particularly vulnerable to non-consensual sex because of interplaying factors such as mental health disorders, a high number of sex partners, engagement in chemsex, and the widespread use of dating apps. The objectives of this study were to assess the occurrence of non-consensual sex, its associated factors, and related help-seeking behavior among PrEP users. We analyzed data from an online survey among PrEP users in Belgium (09/2020-02/2022). Almost one in five participants (34/187, 18.2%) reported having ever experienced non-consensual sex. The most reported form was having sex against one's will, followed by having been given drugs against one's will, and having had sex without a condom against one's will. The vast majority of those who had experienced non-consensual sex (29/34, 85.3%) did not seek help afterward, mostly due to a lack of perceived need (21/29, 72.4%). Reported barriers to seeking help were shame (6/29, 20.7%) and lack of awareness of help services (3/29, 10.3%). Having experienced non-consensual sex in the past five years was associated with younger age and suicidal ideation in a multivariable logistic regression model. We conclude that addressing barriers to non-consensual sex help services is crucial to maximize their use and minimize the consequences of non-consensual sex experiences. PrEP consultations also represent an opportunity to offer such help given PrEP users are already familiar with these PrEP services and engaged in care.

Knowledge and Awareness of Pre-Exposure Prophylaxis Among Men in Sub-Saharan Africa: A Scoping Review Protocol

Introduction

About 39.9 million people were living with HIV as of 2023, and HIV is more prevalent in sub-Saharan Africa. Pre-exposure prophylaxis (PrEP) is highly effective in HIV prevention. Despite the efficacy of PrEP, many persons, including men, do not have adequate knowledge and awareness of PrEP, and reviews on knowledge and awareness among men are scarce. This review aims to assess and synthesize the knowledge and awareness of PrEP among persons assigned as males at birth in sub-Saharan Africa.

Methods and Analysis

The proposed scoping review will be conducted in accordance with the PRISMA Extension for Scoping Reviews (PRISMA-ScR): Checklist and Explanation. The following information sources will be searched to retrieve relevant studies for this review: CINAHL, MEDLINE (Ovid), PubMed, SCOPUS, and Web of Science. Google Scholar, The Union Catalogue of Theses and Dissertations (UCTD) and SA ePublications via SABINET Online, WorldCat Dissertations and Theses via OCLC, ResearchGate, and American Doctoral Dissertations via EBSCOhost. All study designs, except existing reviews, will be included. All screenings (abstract screening and full-text screening) and data extraction will be conducted independently by two reviewers. Quantitative findings will be presented with frequency and percentages, while qualitative thematic analysis will be used to analyze qualitative findings.

Conclusion

This study will map out studies on knowledge and awareness of PrEP among men in sub-Saharan Africa. The results of this review will give insights into what men in sub-Saharan Africa know about PrEP, which can inform future interventions.

Perceptions, experiences and concerns with sexually transmitted infections among current and former PrEP users: a longitudinal qualitative study of gay, bisexual and queer men in Canada

Background Pre-exposure prophylaxis (PrEP) use has been attributed to heightened rates of sexually transmitted infections (STIs), ostensibly due to increased condomless anal sex (CAS) and greater frequency of STI testing. Few qualitative studies have assessed how gay, bisexual and queer men (GBQM) who use PrEP perceive STIs and how these attitudes have evolved post-PrEP uptake. We investigated the perspectives of current and former PrEP users on STIs. Methods Annual, in-depth longitudinal interviews were conducted with 38 current and former PrEP users in Ontario (n =18) and British Columbia (n =20), Canada, as part of a mixed-methods implementation science study (2020-2022). Over 3years, 109 interviews were conducted. Data analysis included reflexive thematic coding and longitudinal recurrent cross-sectional analysis using NVivo 12. Results Four STI-related themes emerged: (1) lack of STI-related concerns due to treatment and prevention optimism, (2) stigma-related concerns, (3) perceived risk among other PrEP users due to increased CAS, and (4) inconsistent testing concerns among non-PrEP users. Over time, some STI-related anxieties decreased with increased knowledge and reduced stigma. However, concerns persisted for other participants due to perceived risky sexual behaviours among other PrEP users and non-PrEP users. Both current and former PrEP users who expressed STI-related apprehensions consistently indicated adopting risk-reduction strategies, including condom use and having fewer sexual partners throughout the study. Conclusions Findings show how varied STI perceptions and experiences among current and former PrEP users shaped sexual decision-making over time. Providers, public health experts, and policymakers should develop a more comprehensive strategy to address STI concerns among GBQM.

Gay and Bisexual Men's Perceptions about a Potential HIV Vaccine within a Post-COVID-19 Era: A Qualitative Study

To end the HIV epidemic, there is need for targeted strategies to reduce HIV incidence for those most vulnerable, including an HIV vaccine. This study seeks to understand the perceptions that non-PrEP using gay and bisexual men and other men who have sex with men (GBMSM) have about a potential HIV vaccine, while contextualizing their perspectives within the context of heightened vaccine hesitancy that has emerged since the COVID-19 pandemic. Between March and May of 2022, GBMSM (N = 20) participated in in-depth interviews, which assessed their perceptions about an HIV vaccine. Interviews were analysed using a codebook approach to thematic analysis. We oversampled for those unvaccinated against COVID-19 as a proxy for vaccine hesitation. Participants expressed a range of enthusiastic support, cautious optimism and skepticism when presented with the possibility of an HIV vaccine. Factors that drove willingness to receive an HIV vaccine included community-oriented altruism, individualized risk-benefit assessment, and/or the perception that a vaccine could provide a beneficial shift in sexual experiences. Participants also expressed hesitations about receiving an HIV vaccine, including concerns about potential side-effects and efficacy, as well as mistrust in the vaccine development process. Notably, participants often evaluated the vaccine in comparison to PrEP and condoms. Participants offered specific insights into information they would like to receive about an HIV and where/how they would like to receive it. Our findings can help inform future HIV vaccine implementation efforts by offering insights into the factors that motivate and deter GBMSM to receive an HIV vaccine.

Perception and barriers to access Pre-exposure Prophylaxis for HIV/AIDS (PrEP) among the MSM (men who have sex with men) Brazilian Amazon: A qualitative study

Pre-exposure prophylaxis (PrEP) is an effective HIV prevention strategy that consists in the use of antiretroviral drugs by seronegative people at risk of HIV. Negative perceptions, inadequate understanding, and access barriers have been associated with decreased medication adherence. Manaus is the largest city in the Brazilian Amazon, where the incidence of HIV/AIDS is high, and the rates of adherence to the antiretroviral treatment for HIV and PrEP are low. In this qualitative study among PrEP users, mostly MSM, we explored perceptions, knowledge, and access barriers. We conducted 21 in-depth interviews with an intentionally sampled group of participants who had used PrEP at least once in their lifetime, selected through the snowball technique, between April and July 2022. A thematic analysis was conducted with a predominantly inductive approach. We highlight three relevant themes: (i) access to information about PrEP and its influences on users, (ii) access, monitoring, and barriers encountered, and (iii) facilitators for PrEP adherence and sexual behaviors. One of the negative perceptions identified in the study involves a misunderstanding of the association between PrEP users and the HIV/AIDS status. Participants revealed that some non-PrEP users suspect that individuals claiming PrEP usage are concealing an HIV-positive status to engage in unprotected sex. Lack of information by health professionals regarding HIV prevention methods poses significant barriers to PrEP access and adherence. Participants emphasized social media's crucial role in PrEP awareness. The results suggest a need to increase digital outreach regarding PrEP, decentralize PrEP services, and provide comprehensive healthcare training to improve the effectiveness of the preventive measure.

Reconciling intimacy and safety: a qualitative systematic review of HIV pre-exposure prophylaxis implementation among gay and bisexual men

This review synthesises qualitative research on pre-exposure prophylaxis (PrEP) uptake by sexual minority men to provide an overarching conceptualisation of the implementation processes involved. Twenty-four studies-comprising 734 participants from USA, UK, France, Canada, and Taiwan-were synthesised using thematic synthesis. The synthesis elucidates the dual significance of PrEP uptake: (1) risk management: reinforcing relational circumstances, and rebalancing safety and risk; and (2) sexual empowerment: reclaiming health and sexuality and refocusing on sexual fulfillment and intimacy. Overall, the findings show how gay and bisexual men use PrEP to reconcile their antagonistic desires for intimacy and safety by recalibrating protection and reimagining intimacy. This review conceptualises the essence of users' experiences of PrEP implementation as reconciliation work-the labour and agency in making and remaking practices to manage discontinuities and incongruities-about the new HIV prevention modality. The concept of reconciliation work illustrates how using PrEP influences users' practices, which in turn, shape the meanings of PrEP use within the community. This work engenders contingent transformations and outcomes beyond HIV protection, encompassing the broader aspects of health and sexuality. Findings support the adoption of more holistic and empowering approaches to sexual health promotion and intervention.

Users' expectations of the new pre-exposure prophylaxis for the HIV modalities

This article aims to discuss the expectations of Homosexual Men, Bisexual Men and a Transgender Woman, who use or want to use an oral pre-exposure prophylaxis (PrEP) for the human immunodeficiency virus (HIV) about PrEP modalities. Sixteen PrEP users, who are followed up in the BCN Checkpoint, were interviewed,. The interviews were audio-recorded, subjected to thematic categorical analysis within the theoretical framework from the praxiographic perspective. They are all adapted to the use of daily oral and event-based PrEP. In relation to the new PrEP modalities (monthly pill; intramuscular injection every two months; subcutaneous injection every six months), they are all very receptive to these possibilities, but they lack information on the specificities of each and specific assessment of their needs. Comments about the use of oral PrEP are positive, and expectations regarding the new PrEP modalities are visibly high. However, the most important thing for the interviewees is the guarantee that they will have follow-up appointments to continue taking care of their affective-sexual health, which is not dependent on the type of PrEP modalities.

Willingness to Use Long-Acting Injectable PrEP Among PrEP Naïve Black and Hispanic Sexual Gender Minority Persons

In December 2021, long-acting injectable pre-exposure prophylaxis (LAI-PrEP) was approved for the prevention of HIV in at-risk adults and adolescents. LAI-PrEP may address adherence issues of daily oral daily PrEP and PrEP stigma. However, studies assessing LAI-PrEP willingness among PrEP naive Black and Hispanic sexual and gender minority (SGM) persons- a group disproportionately impacted by the HIV epidemic in the United States - is rare. To assess the extent of and characteristics of willingness to use LAI-PrEP in a national sample of Black and Hispanic SGM who are self-reported that they have never used PrEP. We analyzed data from a national sample of Black and Hispanic SGM collected between March and August 2020. We used log-binomial regression models to assess characteristics associated with willingness to use LAI-PrEP. Of the overall sample (N = 380), the mean age was 24 (SD = 2.8) and the majority of the sample (54%, n = 205) reported willingness to use LAI-PrEP. In multivariable log-binomial regression models, PrEP stigma was independently associated with less [prevalence ratio (PR) = 0.7, 95% confidence interval (CI) = 0.6, 0.9], while number of sexual partners in the past 12 months was associated with a more willingness to use LAI-PrEP (PR = 1.1, 95% CI = 1.0, 1.2). Our findings highlight the persistence of PrEP stigma as a potential barrier to willingness to use LAI-PrEP in this sample of Black and Hispanic SGM who have never used PrEP. Additional work needs to be done to reduce PrEP stigma more broadly.

HIV-Associated Hypertension: Risks, Mechanisms, and Knowledge Gaps

HIV type 1 (HIV-1) is the causative agent of AIDS. Since the start of the epidemic, HIV/AIDS has been responsible for ≈40 million deaths. Additionally, an estimated 39 million people are currently infected with the virus. HIV-1 primarily infects immune cells, such as CD4+ (cluster of differentiation 4+) T lymphocytes (T cells), and as a consequence, the number of CD4+ T cells progressively declines in people living with HIV. Within a span of ≈10 years, HIV-1 infection leads to the systemic failure of the immune system and progression to AIDS. Fortunately, potent antiviral therapy effectively controls HIV-1 infection and prevents AIDS-related deaths. The efficacy of the current antiviral therapy regimens has transformed the outcome of HIV/AIDS from a death sentence to a chronic disease with a prolonged lifespan of people living with HIV. However, antiviral therapy is not curative, is challenged by virus resistance, can be toxic, and, most importantly, requires lifelong adherence. Furthermore, the improved lifespan has resulted in an increased incidence of non-AIDS-related morbidities in people living with HIV including cardiovascular diseases, renal disease, liver disease, bone disease, cancer, and neurological conditions. In this review, we summarize the current state of knowledge of the cardiovascular comorbidities associated with HIV-1 infection, with a particular focus on hypertension. We also discuss the potential mechanisms known to drive HIV-1-associated hypertension and the knowledge gaps in our understanding of this comorbid condition. Finally, we suggest several directions of future research to better understand the factors, pathways, and mechanisms underlying HIV-1-associated hypertension in the post-antiviral therapy era.

Pre-exposure prophylaxis against HIV infection

Pre-exposure prophylaxis (PrEP) decreases the risk for HIV transmission in high-risk populations. PrEP has been available in Denmark since 2019 and consists of antiretroviral drugs in a combination tablet taken daily or on demand. The effect of this prophylaxis in Denmark is summarized in the review. PrEP is indicated in men and transgender persons with unprotected anal intercourse with multiple male partners in the latest 12 weeks or recent diagnoses of syphilis, chlamydia, or gonorrhoea. PrEP is provided by infectious disease specialists. Continued implementation could significantly reduce HIV transmission and potentially end the epidemic in Denmark.

Structural vulnerabilities and PrEP awareness among Boston heterosexuals and people who inject drugs at risk for HIV: findings from 2018 to 2019 cycles from the Boston, MA site of the NHBS

Little is known about biopsychosocial factors relating to pre-exposure prophylaxis (PrEP) awareness among people with either heterosexual or injection drug use HIV risk behaviors. Participants engaged in vaginal/anal sex with a person of the opposite sex (N = 515) or were people who injected drugs (PWID; N = 451) in the past 12 months from 2018-2019 in Boston, MA. We examined associations between PrEP awareness and: homelessness; perceived HIV-related stigma; country of birth; bacterial STDs, chlamydia, and/or gonorrhea in the past 12 months, lifetime hepatitis C virus (HCV) infection, sexual orientation, and poverty. More PWID (36.8%) were aware of PrEP than people with heterosexual HIV risk (28%; p = .001). Among people with heterosexual risk, homelessness (aOR = 1.99, p = .003), and among PWID: homelessness (aOR = 2.11, p = .032); bacterial STD (aOR = 2.96, p = .012); chlamydia (aOR = 6.14, p = .008); and HCV (aOR = 2.40, p < .001) were associated with increased likelihood of PrEP awareness. In the combined sample: homelessness (aOR = 2.25, p < .001); HCV (aOR = 2.18, p < .001); identifying as homosexual (aOR = 3.71, p = .036); and bisexual (aOR = 1.55, p = .016) were each associated with PrEP awareness. Although having an STD, HCV, identifying as homosexual or bisexual, and experiencing homelessness were associated with increased PrEP awareness, most participants were unaware of PrEP. Efforts to increase PrEP awareness could engage PWID and heterosexual HIV risk behavior.

Doxycycline as Postsexual Exposure Prophylaxis: Use, Acceptability, and Associated Sexual Health Behaviors Among a Multi-Site Sample of Clinical Trial Participants

Doxycycline postexposure prophylaxis (doxy-PEP) reduces sexually transmitted infections (STIs) in men who have sex with men (MSM) and transgender women (TGW). In a clinical trial of doxy-PEP, we sought to assess acceptability, impact, and meaning of doxy-PEP use among MSM/TGW. We conducted semistructured, in-depth 1:1 interviews with MSM and TGW enrolled in the intervention arm of the Doxy-PEP study. We queried motivations for and meaning of use, attitudes, beliefs, adherence, effect on sexual behaviors, and partner, community, and structural factors related to use. We coded interview transcripts into content areas, followed by thematic analysis. We interviewed 44 participants (median age 38), 2% were TGW, 17% Black, 61% White, 30% Hispanic, and 45% persons with HIV. We identified three overarching themes. First, participants found doxy-PEP acceptable, and believed it was effective based on their history of STIs, easy to adhere to, and acceptable to sex partners. Second, doxy-PEP benefited their quality of life and mental health, offering "peace of mind" by reducing their anxiety about acquisition or unwitting transmission of STIs. Participants reported feeling more "in control" of preventing STIs, and positive about supporting their personal, partner, and community health. Third, impact on sexual behavior was variable, with most reporting no change or a brief initial change. Participants in a multi-site clinical trial of doxycycline for STI prevention perceived it to be efficacious, and that it provided quality-of-life benefits, including reduced anxiety and sense of control over sexual health. Doxy-PEP had limited impact on sexual behavior. Clinicaltrials.gov: NCT03980223.

Use of preexposure prophylaxis and condom purchasing decisions

Preexposure prophylaxis (PrEP) prevents human immunodeficiency virus (HIV) but not other sexually transmitted infections (STIs). Men who have sex with men (MSM) who take PrEP tend to report reduced condom use, but little is known about the underlying mechanisms. For this study, MSM who take PrEP (i.e., PrEP experienced; n = 88) and MSM who do not (i.e., PrEP naïve; n = 113) completed an online study, including the condom purchase task (CoPT). The CoPT assesses decisions to purchase condoms across escalating prices (range: free-$55) for sex with different types of hypothetical partners: those least likely to have an STD (least STD) and those that participants most want to have sex with (most want sex with). When condoms were free, PrEP-experienced MSM had a lower rate of condom purchasing than did PrEP-naïve MSM. For both partner types, PrEP-experienced MSM reached a price break point (i.e., would not buy condoms) at a lower price than did PrEP-naïve pariticipants. For the most-want-sex-with partner at the price at which participants elected not to buy condoms, only 23% of PrEP-experienced MSM chose to abstain from sex when not purchasing condoms versus 53% among PrEP-naïve MSM. Similar patterns were observed for the least-STD partner. The results support the potential utility of the CoPT in identifying behavioral mechanisms related to condom use and PrEP.

Recommendations for Improving Oral Pre-exposure Prophylaxis Implementation and Social Marketing in Ugandan Fisherfolk Communities: A Qualitative Exploration

Background: HIV is hyperendemic among fisherfolk in Sub-Saharan Africa, especially around Lake Victoria, Uganda. Purpose/Research Design: We conducted cross-sectional semi-structured interviews about oral pre-exposure prophylaxis (PrEP) implementation with 35 Ugandan fisherfolk (15 women, 20 men) and 10 key stakeholders (healthcare providers, policymakers, community leaders). We used a directed content analysis approach based on implementation science and social marketing frameworks. Results: Participants showed high acceptability for PrEP. Anticipated barriers among fisherfolk included stigma (due to similar medications/packaging as HIV treatment); misconceptions; mobility, competing needs, poverty, and partner conflict. Anticipated provider barriers included insufficient staffing and travel support. Recommendations included: change PrEP packaging; integrate PrEP with other services; decrease PrEP refill frequency; give transportation resources to providers; train more healthcare workers to provide PrEP to fisherfolk; and use positively framed messages to promote PrEP. Conclusions: Results can inform policymakers and healthcare organizations on how to overcome barriers to PrEP scale-up in most at-risk populations with poor healthcare access.

Moderating Effect of Pre-Exposure Prophylaxis Use on the Association Between Sexual Risk Behavior and Perceived Risk of HIV Among Brazilian Gay, Bisexual, and Other Men Who Have Sex With Men: Cross-Sectional Study

BACKGROUND

Gay, bisexual, and other men who have sex with men (MSM) with a higher perceived risk of HIV are more aware of and willing to use pre-exposure prophylaxis (PrEP). PrEP is an effective HIV prevention strategy, but there is a lack of data on how PrEP use might moderate the relationship between sexual risk behavior and perceived risk of HIV. Moreover, most studies measure perceived risk of HIV via a single question.

OBJECTIVE

We estimated the moderating effect of PrEP use on the association between sexual risk behavior and perceived risk of HIV, measured with the 8-item Perceived Risk of HIV Scale (PRHS), among Brazilian MSM.

METHODS

A cross-sectional, web-based survey was completed by Brazilian Hornet app users aged ≥18 years between February and March 2020. We included data from cisgender men who reported sex with men in the previous 6 months. We evaluated the moderating effect of current PrEP use on the association between sexual risk behavior, measured via the HIV Incidence Risk Index for MSM (HIRI-MSM), and perceived risk of HIV, measured by the PRHS. Higher HIRI-MSM (range 0-45) and PRHS (range 10-40) scores indicate greater sexual behavioral risk and perceived risk of HIV, respectively. Both were standardized to z scores for use in multivariable linear regression models.

RESULTS

Among 4344 cisgender MSM, 448 (10.3%) were currently taking PrEP. Current PrEP users had a higher mean HIRI-MSM score (mean 21.0, SD 9.4 vs mean 13.2, SD 8.1; P<.001) and a lower mean PRHS score (mean 24.6, SD 5.1 vs mean 25.9, SD 4.9; P<.001) compared to those not currently taking PrEP. In the multivariable model, greater HIRI-MSM scores significantly predicted increased PRHS scores (β=.26, 95% CI 0.22-0.29; P<.001). PrEP use moderated the association between HIRI-MSM and PRHS score (interaction term β=-.30, 95% CI -0.39 to -0.21; P<.001), such that higher HIRI-MSM score did not predict higher PRHS score among current PrEP users.

CONCLUSIONS

Our results suggest current PrEP users have confidence in PrEP's effectiveness as an HIV prevention strategy. PrEP's effectiveness, positive psychological impact, and the frequent HIV testing and interaction with health services required of PrEP users may jointly influence the relationship between sexual risk behavior and perceived risk of HIV among PrEP users.

Navigating the Viral Divide: Sexual and Gender Minority Community Perspectives on Treatment as Prevention

Since it was established that HIV-positive individuals who maintain an undetectable viral load are unable to sexually transmit HIV (U=U), treatment as prevention (TasP) has become an important biomedical HIV prevention option. Many have remained optimistic that TasP, combined with pre-exposure prophylaxis (PrEP), will help close the "viral divide" between those living with and without HIV. This qualitative interview study of 62 sexual and gender minority (SGM) individuals of mixed serostatuses explored community perspectives regarding TasP, including the meaning of undetectability and how U=U impacts understandings of serodifference. Five key themes emerged from interviews: (1) undetectable does not equal HIV-negative, (2) PrEP is more promoted than TasP, (3) TasP increases openness to serodifferent sex, (4) rejection of TasP absolutism, and (5) the importance of layering prevention strategies. These findings suggest that while TasP is helping to bridge the viral divide, serostatus distinctions remain prevalent and important to many SGM individuals.

Barriers and facilitators to HIV pre-exposure prophylaxis for cisgender and transgender women in the UK

Uptake of oral HIV pre-exposure prophylaxis (PrEP) among cisgender and transgender women in the UK has been low. In this Review, we explore the barriers and facilitators to PrEP access for these groups, with a focus on health equity. We included 20 studies, including seven abstracts presented at conferences. The study samples were disparate, with minimal overlap between papers. We identified barriers at the individual, interpersonal, and structural levels, including poor awareness and acceptability; stigma, race, and ethnicity; restricted access to PrEP; and exclusion from clinical trials. We found hidden subpopulations of women who could potentially benefit from PrEP, of whom little is known about their PrEP knowledge, preferences, and access due to a lack of UK research. These subpopulations include non-Black African women, transgender women, sex workers, migrant women, women experiencing intimate partner violence, incarcerated women, and women who inject drugs. We highlight opportunities to address these obstacles. Research on the use of PrEP by women in the UK is scarce, and existing research has poor granularity. Without a better understanding of the needs and preferences of the full spectrum of women who could benefit from PrEP, the UK will not reach zero transmissions by 2030.

Binge Drinking Moderates Unprotected Sex Among HIV Sero-Similar Same Sex Male Couples: An Actor-Partner Interdependence Model

Most new HIV diagnoses in the US occur among sexual minority men (SMM). The majority (69%) of new HIV diagnoses among US SMM are due to transmission from main sex partners. We identified multilevel correlates of unprotected anal intercourse (UAI; condomless anal intercourse while not using a biomedical strategy) among SMM couples using the Actor Partner Interdependence Model (APIM). Participants were US SMM over 18 years, with a primary male partner > 6 months. Couples were recruited online from April 2016 until June 2017 and interviewed using self-administered computer-assisted surveys. We used a series of APIM regressions to assess multilevel associations with UAI. We also tested the moderating role of an individual's binge drinking on the relationship between HIV status similarity and UAI. Among 798 participants (n = 411 couples), 61% reported UAI in the past 6 months. Binge drinking (52%) and physical intimate partner violence (IPV; 34%) were considerably high within our sample. Actor's binge drinking, reporting experiencing and/or perpetrating physical IPV, and partner's trust were positively associated with UAI. Actor having other sexual partner(s), using illegal drugs (not marijuana), and length of relationship were negatively associated with UAI. Binge drinking positively moderated UAI among HIV serostatus similar partners. HIV prevention programming should integrate components on IPV and binge drinking reduction- especially among HIV serostatus similar couples.

"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.

Explicit Relationship Agreements and HIV Pre-exposure Prophylaxis Use by Gay and Bisexual Men in Relationships

Relationship agreements are important for HIV prevention among gay and bisexual men (GBM) in relationships, with research earlier in the HIV epidemic often finding that agreements specified monogamy or condom use with casual partners. There is evidence that HIV pre-exposure prophylaxis (PrEP) has shifted sexual practices among some men in relationships, such as allowing condomless sex with casual partners, but there has been little attention paid to relationship agreements among GBM who use PrEP. In this paper, we analyzed national, Australian, cross-sectional data from an online survey completed by non-HIV-positive GBM in 2021 (N = 1,185). Using logistic regression, we identified demographic characteristics, sexual practices and the types of relationship agreement that were associated with PrEP use among GBM in relationships. Using Pearson's chi-squared tests, we explored whether PrEP users in relationships reported similar sexual practices to PrEP users not in relationships. PrEP use among GBM in relationships was independently associated with older age, identifying as gay, being in a non-monogamous relationship, having a spoken (explicit) relationship agreement, having a primary HIV-negative partner taking PrEP or a primary partner living with HIV, reporting recent condomless casual sex, reporting an STI diagnosis in the past year, and knowing at least one other PrEP user. We found that PrEP users in relationships had similar sexual practices to PrEP users not in relationships. GBM in relationships who have casual sex and who meet PrEP suitability criteria may be good candidates for PrEP. Our findings suggest that explicit relationship agreements remain important for HIV prevention, and they support PrEP use among GBM in relationships.

Deep learning for topical trend discovery in online discourse about Pre-Exposure Prophylaxis (PrEP)

Pre-Exposure Prophylaxis (PrEP) interventions are increasingly prevalent on social media. These data can be mined for insights about PrEP that may not be as apparent in surveys including personal musings about PrEP and barriers/facilitators to PrEP uptake. This study explores online discourse about PrEP using an interdisciplinary public health and computational informatics approach. We collected (N = 4,020) tweets using Twitter's Application Programming Interface (API). These data underwent a three-step neural network/deep learning process to identify clusters within these tweets and relative similarity/dissimilarity between clusters. We identified 25 distinct clusters from our original collection of tweets. These clusters represent general information about PrEP, how PrEP is communicated among diverse groups, and potential pockets of misinformation and disinformation regarding PrEP. Specific clusters of interest include discussions of medication side effects, social perception of PrEP usage, and concerns with costs and barriers to access of PrEP interventions. Our approach revealed diverse ways PrEP is contextualized online. Importantly this information can be leveraged to identify points of possible intervention for disinformation and misinformation about PrEP.

HPV vaccination and HIV preexposure prophylaxis (PrEP): Missed opportunities for anal cancer prevention among at risk populations

Gay, bisexual, and other men who have sex with men (GBM), in addition to transgender women who have sex with men (TW), are at disproportionate risk for anal cancer. Anal cancer can be prevented with HPV vaccination, but uptake among adult GBM/TW is low. Targeted HPV vaccination during the clinical management of pre-exposure prophylaxis (PrEP) is an unexplored strategy relevant to these populations. The purpose of this study was (1) to determine the need for HPV vaccination among GBM and transgender women PrEP users and (2) to identify correlates of HPV vaccination among PrEP users. Secondary analysis of the 2020 Pennsylvania LGBT Health Needs Assessment was conducted to estimate prevalence ratios of HPV vaccination among PrEP users. Overall, 43.8% of the sample had initiated HPV vaccination. Vaccine initiation was significantly lower among respondents 27 to 35 (PR = 0.64; 95% CI: 0.49-0.83) and 36 to 45 (PR = 0.38; 95% CI: 0.25-0.58). Respondents who had received Hepatitis A vaccination were significantly more likely to have had initiated HPV vaccination after adjusting for age (aPR = 2.60; 95% CI: 1.75-3.84). Overall, more than half of eligible GBM and TW engaged in PrEP care have not initiated HPV vaccination and represent potential missed opportunities for anal cancer prevention.

Talking to My Partners About PrEP: Factors Associated with PrEP-Related Communication in a Longitudinal US Study of Sexual Minority Men Living with HIV

Treatment as prevention and pre-exposure prophylaxis (PrEP) have reduced HIV transmission among sexual minority men (SMM). However, little is known about PrEP-related communication in serodiscordant partnerships. In 2015-2016, 965 US SMM living with HIV (Mage = 39; 63% White, 19% Black, 18% Latinx) enrolled in a year-long longitudinal study with surveys every 3 months (2,850 surveys). Multilevel models explored factors associated with PrEP-related communication with HIV-negative partners. Most participants (77%) reported PrEP-related communication. Participants were more likely to discuss PrEP during periods with more sexual partners, AOR = 2.89, p < .001, and group sex, AOR = 1.99, p = .001. Those with more partners on average, β = 0.48, p < .001, and those engaging in other drug use more frequently, β = 0.11, p = .002, were more likely to discuss PrEP. PrEP-related communication was more common for men who disclosed their HIV status, β = 0.22, p < .001, and who had undetectable viral loads, β = 0.25, p = .007. Communication was also more common for those with higher incomes, β = 0.12, p = .02, and from larger cities, β = 0.07, p = .048, and less common for Black participants, β =  - 0.29, p = .003, and older participants, β =  - 0.18, p < .001. PrEP-related communication increased over the course of the study, AOR = 1.16, p= .02. PrEP can confer additional HIV prevention benefits within serodiscordant partnerships, and future research should continue to explore the role PrEP plays in these partnerships.

HIV Pre-Exposure Prophylaxis (PrEP) among men who have sex with men: peer communication, engagement and social networks

Abstract HIV Pre-Exposure Prophylaxis (PrEP) has renewed optimism in controlling the HIV epidemic, despite its continued growth among men who have sex with men (MSM). The popularity of dating-sexual dating apps and digital media platforms in exchanging information and experiences about PrEP on peer social networks is recognized. However, studies on contexts, motivations, and scope in HIV prevention are scarce. The article aims to understand the dynamics of virtual and face-to-face peer networks among MSM for the decision to use PrEP, its disclosure, and publicity. Qualitative study using semi-structured interviews with 48 PrEP users from five Brazilian cities. Most interviewees share information and experiences about PrEP in peer social networks. However, its publication reveals tensions arising from the permanence of stigmas associated with homosexuality and HIV. The protagonism in exposing the use of PrEP expresses commitment to attracting new users. The relevance of peer social networks in sharing experiences and information about PrEP has the potential to diversify the target audience and expand and democratize PrEP coverage in the country.

Scaling up preexposure prophylaxis to maximize HIV prevention impact

PURPOSE OF REVIEW

Ten years since the first regulatory approval of oral HIV preexposure prophylaxis (PrEP), this review summarizes PrEP uptake, the role of ambitious PrEP targets, emerging evidence of impact on the HIV epidemic and innovative approaches to increasing PrEP uptake.

RECENT FINDINGS

PrEP uptake among people at risk of HIV has been slow, but has accelerated in recent years, particularly in gay and bisexual men in a limited number of high-income settings and recently in heterosexuals at risk of HIV in sub-Saharan Africa. However, UNAIDS 2020 PrEP targets and HIV prevention targets were missed by large margins. Although UNAIDS testing and treatment targets have galvanised public health action, in contras, PrEP targets have been lower profile and insufficiently ambitious. Parts of the USA, Australia and the UK with high PrEP coverage have demonstrated striking reductions in HIV infection at the population level, as PrEP is introduced at scale. Scaling up PrEP uptake will require innovations in PrEP promotion, simplified models of care, improved adherence interventions, improved choice in the form of longer-acting PrEP and interventions to ensure that all those who can benefit from PrEP can access it.

SUMMARY

PrEP is a revolutionary HIV prevention tool, which if ambitiously scaled up could drive HIV transmission towards elimination. Highly publicized and ambitious PrEP targets could help drive this.

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.

Prescribing as affective clinical practice: Transformations in sexual health consultations through HIV pre-exposure prophylaxis

New medicines can transform routines and priorities in clinical practice, but how do clinicians think and feel about these changes, and how does it affect their work? In Australia, the HIV prevention regimen pre-exposure prophylaxis (PrEP) has been rapidly rolled out, transforming the sexual cultures and practices of users, but less attention has been given to the ways PrEP has reconfigured clinical practice. This paper draws on 28 qualitative semi-structured interviews conducted between 2019 and 2020 with PrEP-providing doctors and nurses in Australia to consider how they have affectively engaged with PrEP and put it into practice. Through a reflexive thematic analysis, we explore how clinicians adapted to PrEP, how the field of HIV prevention has been transformed, and how these developments have changed how clinicians approach patients. While the introduction of PrEP was initially received with uncertainty and shock, clinicians described PrEP as enjoyable to prescribe, and better aligned with the moral duties of sexual health consultations than existing HIV prevention strategies like condoms. Through approaching clinical work as an 'affective practice', we argue for attending not only to how new interventions change expectations and practices, but also how these changes are felt and valued by clinicians.

Assessing the Information-Motivation-Behavioral Skills Model to Predict Pre-exposure Prophylaxis Adherence Among Black Men Who have Sex with Men and Transgender Women in a Community Setting in New York City

The Information-Motivation-Behavioral Skills (IMB) Model has been used to understand adherence to medications and intentions to uptake pre-exposure prophylaxis (PrEP) to prevent HIV infection. In the current study, the IMB Model was used to understand factors that predict adherence to PrEP among a community-based cohort of 204 Black men who have sex with men (MSM) and transgender women (TGW) using structural equation modeling. PrEP motivation was directly associated with PrEP behavioral skills (β = 0.320, p = 0.009), and PrEP behavioral skills were directly associated with PrEP adherence (β = 0.416, p = 0.001). PrEP knowledge and PrEP motivation were not associated with PrEP adherence, directly or indirectly. The analysis identified intervenable factors that predicted PrEP adherence. Screening for motivation and behavioral skills could be used to identify where additional support to improve PrEP adherence is needed, or whether to offer alternative PrEP modalities or delivery strategies.

"What other choices might I have made?": Sexual Minority Men, the PrEP Cascade and the Shifting Subjective Dimensions of HIV Risk

The PrEP Cascade is a dominant framework for investigating barriers to HIV pre-exposure prophylaxis (PrEP), an HIV prevention tool. We interviewed 37 PrEP users and 8 non-PrEP users in Ontario and British Columbia, Canada, about their decision-making through the Cascade. Participants were HIV-negative gay, bisexual, and queer men (GBQM). The data were analyzed using thematic analysis. PrEP decision-making was based on pragmatic considerations (logistics, costs, and systemic barriers), biomedical considerations (efficacy, side-effects, and sexually transmitted infections), and subjective considerations (identity, politics, and changing sexual preferences). Affective attachments to established versions of "safer sex" (condoms and serosorting) made some GBQM less likely to try PrEP. Some GBQM expressed increased social expectations to use PrEP, have condomless sex, and serodifferent sex. These findings support offering PrEP at no-cost, offering individualized counseling and community-based opportunities to discuss PrEP use and changing sexual practices, and improving communication on the manageability of PrEP side-effects.

The potential effect of pre-exposure prophylaxis (PrEP) roll-out on sexual-risk behaviour among adolescents and young people in East and southern Africa

Pre-exposure prophylaxis (PrEP) is an HIV-prevention strategy recommended for those at high-risk of infection, including adolescents and young people (AYP). We explored how PrEP roll-out could influence sexual risk behaviour among AYP in East and southern Africa. Twenty-four group discussions and 60 in-depth interviews were conducted with AYP between 13 and 24 years old, recruited from community settings in Uganda, Zimbabwe and South Africa, from September 2018 to January 2019. Participants perceived that PrEP availability could change sexual behaviour among AYP, influencing: (1) condom use (increased preference for condomless sex, reduced need and decrease in use of condoms, relief from condom use discomfort, consistent condom use to curb sexually transmitted infections and pregnancies); (2) sexual activities (increase in sexual partners and sexual encounters, early sexual debut, sexual experimentation and peace of mind during risky sex, sexual violence and perversion); (3) HIV risk perception (neglect of other HIV prevention strategies, unknown sexual partner HIV status, adoption of PrEP). PrEP initiation may be associated with increased interest in sexual activities and risky sexual behaviour among AYP. PrEP should be included as part of a combination package of HIV prevention strategies for AYP with methods to prevent other sexually transmitted infections and unwanted pregnancies.

Daily Marijuana Use Predicts HIV Seroconversion Among Black Men Who Have Sex with Men and Transgender Women in Atlanta, GA

We evaluated whether different types of substance use predicted HIV seroconversion among a cohort of 449 Black men who have sex with men (MSM) and transgender women (TGW). A community-based sample was recruited in Atlanta, GA between December 2012 and November 2014. Participants completed a survey and were tested for STIs (Chlamydia and gonorrhoeae using urine samples and rectal swabs) at baseline. HIV testing was conducted at 12-months post enrollment. Multivariable binary logistic regression was used to estimate adjusted odds ratios (aORs) and 95% confidence intervals (CI) for associations between substance use and HIV seroconversion. By 12-month follow-up, 5.3% (n = 24) of participants seroconverted. In multivariable analyses, daily marijuana use was positively associated with HIV seroconversion (aOR 3.07, 95% CI 1.11-8.48, P = 0.030). HIV incidence was high and daily marijuana use was associated with a more than threefold increased odds of HIV seroconversion among a community-based cohort of Black MSM and TGW.

Beyond HIV prevention: Additional individual and community-level benefits of PrEP among Latino gay and bisexual men

BACKGROUND

HIV infections disproportionately impact Latino gay and bisexual men (GBM) in the United States. Pre-Exposure Prophylaxis (PrEP) is a proven prevention strategy that can help reduce new HIV infections in this population. Unfortunately, PrEP adoption and persistence among Latino GBM remain low. The added benefits of using PrEP experienced by Latino GBM can provide important insights to inform the development of PrEP messaging to motivate this population to explore and consider PrEP as an appropriate and acceptable HIV prevention tool.

METHODS

We conducted in-depth interviews with Latino GBM PrEP users to explore positive feelings and emotions, and additional benefits gained from using PrEP. Data were analyzed using thematic analysis.

RESULTS

A total of 29 Latino GBM completed the study interview. The average age of participants was 30 years, and the mean length of time using PrEP was 17.1 months. Five themes were constructed from the data representing the additional benefits gained by Latino GBM PrEP users, and included: (1) reduced fear, anxiety, and stress about HIV, HIV testing, and sex; (2) feeling empowered and in control of their HIV risk; (3) greater awareness of sexual risk behaviors and sexual health; (4) greater sexual exploration and pleasure, and comfort having condomless sex; and (5) a greater connection to community and a feeling of contributing to the elimination of HIV.

CONCLUSIONS

The added benefits identified in this study represent a range of social, emotional, and psychological benefits that Latino GBM experience while using PrEP. They speak to the complementary benefits that PrEP can bring to Latino GBM who decide to use the medication, that go beyond HIV prevention. These findings can inform the development of future PrEP messaging to help improve motivation for PrEP uptake and persistent use among Latino GBM.
