Preferences for Injectable PrEP Among Young U.S. Cisgender Men and Transgender Women and Men Who Have Sex with Men

Young men who have sex with men account for approximately 20% of incident HIV infections in the U.S. Antiretroviral pre-exposure prophylaxis (PrEP) administered as a daily pill has been shown to decrease HIV acquisition in at-risk individuals. New modalities for PrEP are being developed and tested, including injectable PrEP; however, acceptability of these emerging modalities has not yet been examined in youth. We conducted six focus groups with 36 young men and transgender men and women who have sex with men in Boston, Chicago, and Los Angeles in 2016 to assess interest in and preference for different PrEP modalities. Youth were purposively recruited based on diversity of age, race/ethnicity, and prior PrEP experience. Data were coded using content coding based on key domains of the interview guide, in particular around the central themes of interest in and barriers and facilitators to injectable PrEP use. Participants were knowledgeable about oral PrEP but suggested barriers to broader uptake, including stigma, marginalization, and access to information. While participants were split on preference for injectable versus oral PrEP, they agreed quarterly injections may be more manageable and better for those who have adherence difficulties and for those who engage in sex more frequently. Concerns specific to injectable PrEP included: severity/duration of side effects, pain, level of protection prior to next injection, distrust of medical system and injections, and cost. Understanding barriers to and preferences for diverse prevention modalities will allow for more HIV prevention options, improved products, and better interventions, thus allowing individuals to make informed HIV prevention choices.     

Stigma Communication Surrounding PrEP: The Experiences of A Sample of Men Who Have Sex With Men

HIV is a serious problem in the USA, particularly for men who have sex with men (MSM). A new means of HIV prevention, called pre-exposure prophylaxis (PrEP), has been shown to be highly effective. However, in spite of earning FDA approval, adoption of PrEP by MSM has been limited. The purpose of this study was to examine the experiences of a sample of 38 MSM who have adopted PrEP, focusing on communication with healthcare providers and social networks. In-depth interviews were used to collect data. Findings revealed that stigmatization by healthcare providers as well as stigmatization by other MSM was a relatively common experience for participants. Additionally, participants described that a high level of health literacy, health advocacy, and communication skill were necessary to adopt PrEP. Given these findings, strategies are suggested for improving MSM’s healthcare and increasing rates of PrEP adoption.     

HIV Pre-Exposure Prophylaxis,Condoms, or Both? Insights on Risk Compensation Through a Discrete Choice Experiment and Latent Class Analysis Among Men Who Have Sex With Men

ObjectivesWe considered how decision making around human immunodeficiency virus (HIV) pre-exposure prophylaxis (PrEP) among gay, bisexual, and other men who have sex with men (GBMSM) is made in the context of one’s perceived risk of HIV acquisition and the availability of condoms.MethodsWe recruited 648 GBMSM aged 18 years old and residing in Singapore through Grindr. Participants were given information on PrEP and participated in a discrete choice experiment requiring them to choose between 2 baskets of PrEP attributes and compare the chosen “PrEP only” option to default options of “condoms only” or “PrEP with condoms.” Generalized multinomial logit model was used to examine the scaling effect and preference heterogeneity. Latent class analysis was conducted to examine preference heterogeneity in the sample.ResultsLatent class analysis revealed 3 classes of GBMSM: PrEP conservatives (53.9%), moderates (31.1%), and liberals (14.9%). PrEP conservatives were more likely to report greater utility when using condoms only compared with PrEP only, as well as PrEP with condoms, compared with PrEP only, and more likely to report the lowest utility for PrEP as perceived HIV risk increased. PrEP liberals were more likely to report greatest utilities for PrEP only compared with condoms only, as well as PrEP only compared with PrEP with condoms. The utility for PrEP was not affected by perceived risk of HIV or sexually transmitted infections when risks were low.ConclusionThis study provides some evidence for risk compensation among a class of GBMSM who already perceived themselves to be good candidates for PrEP before the discrete choice experiment.     

The Association Between Homophily on Illicit Drug Use and PrEP Conversations Among Latino Men Who Have Sex with Men Friends: A Dyadic Network and Spatially Explicit Study

Despite the wide availability of PrEP, Latino men who have sex with men (LMSM) continue to experience access barriers. Novel HIV prevention research strategies to increase PrEP uptake and adherence among the high incidence populations, such as LMSM who misuse drugs, include social network analyses. This study identified the associations of drug use homophily within LMSM friendship networks and PrEP promotion conversations and described the physical overlap between geographic drug risk areas with conversations of PrEP promotion. Respondent-driven sampling was used to recruit 10 sociocentric networks. Quadratic assignment procedure (QAP) correlations and multiple regression QAPs were used to identify influences of drug use homophily, and geocoding and visualizations to describe drug use polygons and PrEP conversations. Friendship relationships in which both friends used cocaine or marijuana were more likely to report PrEP-related conversations in the past six months. The likelihood of talking about PrEP in the next six months was higher among dyads with cocaine use homophily and ecstasy use homophily, while lower among dyads with marijuana use homophily. Participants reported using marijuana and cocaine throughout Miami-Dade County while ecstasy polygons were mostly in urban areas. The majority of drug polygons associated with PrEP conversations were located in north and central Miami. Future interventions can consider enrolling entire sociocentric friendship groups, configuring friendship networks to connect those without PrEP information to those with information, and incorporating peer leaders.

     

Readiness for Use of HIV Preexposure Prophylaxis Among Men Who Have Sex With Men in Malawi: Qualitative Focus Group and Interview Study

BackgroundMen who have sex with men (MSM) are a key group for HIV interventions in Malawi considering their high HIV prevalence (17.5% compared to 8.4% among men in the general population). The use of oral preexposure prophylaxis (PrEP) presents a new opportunity for MSM to be protected. We present the findings from a qualitative assessment designed to assess awareness of and willingness and barriers to using PrEP among MSM in Malawi.ObjectiveThe 3 main objectives of this assessment were to determine: (1) awareness of PrEP, (2) factors that influence willingness to use PrEP, and (3) potential barriers to PrEP use and adherence among MSM in order to guide the design and implementation of a PrEP program in Malawi.MethodsAhead of the introduction of PrEP in Malawi, a qualitative study using in-depth interviews (IDIs) and focus group discussions (FGDs) was conducted in October 2018 in Blantyre, Lilongwe, and rural districts of Mzimba North and Mangochi. With support of members of the population, study participants were purposively recruited from 4 MSM-friendly drop-in centers where MSM receive a range of health services to ensure representativeness across sites and age. Participants were asked what they had heard about PrEP, their willingness to use PrEP, their barriers to PrEP use, and their preferences for service delivery. The data were analyzed using a thematic content analysis framework that was predetermined in line with objectives.ResultsA total of 109 MSM were interviewed—13 through IDIs and 96 through FGDs. Most participants were aware of PrEP as a new HIV intervention but had limited knowledge related to its use. However, the majority were willing to use it and were looking forward to having access to it. IDI participants indicated that they will be more willing to take PrEP if the dosing frequency were appropriate and MSM were involved in information giving and distribution of the drug. FGD participants emphasized that places of distribution and characteristics of the service provider are the key factors that will affect use. Knowing the benefits of PrEP emerged as a key theme in both the IDIs and FGDs. Participants highlighted barriers that would hinder them from taking PrEP such as side effects which were cited in IDIs and FGDs. Key factors from FGDs include cost, fear of being outed, drug stockouts, fear of being known as MSMs by wives, and lack of relevant information. FGDs cited stigma from health care workers, forgetfulness, and community associated factors.ConclusionsDespite having inadequate knowledge about PrEP, study participants were largely willing to use PrEP if available. Programs should include an effective information, education, and communication component around their preferences and provide PrEP in MSM-friendly sites.     

A Qualitative Study of Medical Mistrust,Perceived Discrimination,and Risk Behavior Disclosure to Clinicians by U.S. Male Sex Workers and Other Men Who Have Sex with Men: Implications for Biomedical HIV Prevention

Access to biomedical HIV prevention technologies such as pre-exposure prophylaxis (PrEP) requires individuals to disclose risk behavior to clinicians, but experiences of discrimination and medical mistrust may limit disclosure among male sex workers and other MSM. We explored experiences of perceived discrimination, medical mistrust, and behavior disclosure among male sex workers compared to other men who have sex with men (MSM). We conducted 56 interviews with MSM and compared findings about medical mistrust, discrimination, and disclosure for 31 men who engaged in sex work vs. 25 men who did not. MSM who engaged in sex work reported more medical mistrust and healthcare discrimination due to issues beyond MSM behavior/identity (e.g., homelessness, substance use, poverty). MSM who did not report sex work described disclosing sex with men to clinicians more often. Both subgroups reported low PrEP awareness, but willingness to disclose behavior to obtain PrEP. Medical mistrust and perceived discrimination create barriers for sexual behavior disclosure to clinicians, potentially impeding access to PrEP and other forms of biomedical HIV prevention. These barriers may be higher among male sex workers compared to other MSM, given overlapping stigmas including sex work, substance use, homelessness, and poverty. An intersectionality framework for understanding multiple stigmas can help to identify how these dynamics may limit access to biomedical HIV prevention among male sex workers, as well as suggesting strategies for addressing stigmas to improve the delivery of PrEP and other HIV prevention approaches in this population.     

Drug and Alcohol Use with Condomless Anal Sex among Men Who Have Sex with Men in Melbourne,Australia: A Retrospective Data Analysis from 2011 to 2017

Rises in condomless anal sex among men who have sex with men (MSM) have been reported over the last decade but there is less certainty about the role that drugs, alcohol, play in this change. We examined the changes in drug and alcohol use among 22,255 MSM reporting condomless anal sex at Melbourne Sexual Health Centre in 2011–2017. There was a 7% annual increase in using drugs before and/or during condomless anal sex but a 3% annual reduction in condomless anal sex while drunk. MSM taking PrEP were more likely to report condomless anal sex with drug use (AOR: 1.21; 95%CI: 1.07–1.37) and alcohol use (AOR: 1.29; 95%CI: 1.14–1.46) compared with MSM not taking PrEP.

     

Gendered Social Institutions and Preventive Healthcare Seeking for Black Men Who Have Sex with Men: The Promise of Biomedical HIV Prevention

Research on gender and health, including research conducted among Black men who have sex with men (BMSM), has primarily focused on how gender norms and roles shape healthcare engagement. Here we advance that work by demonstrating how a broader theorization of gender, particularly one that moves beyond gender norms and performance to incorporate structures such as the healthcare system and the labor market, can facilitate an understanding of how gender affects preventive healthcare seeking among BMSM, particularly the uptake of pre-exposure prophylaxis (PrEP), a promising approach to alleviate HIV disparities. This article is based on a year-long ethnographic study conducted in New York City with BMSM (n?=?31; three interviews each) and community stakeholders (n?=?17). Two primary findings emerged: (1) the labor market systematically excluded the men in our sample, which limited their ability to access employer-sponsored healthcare. Such discrimination may promote overt demonstrations of masculinity that increase their HIV vulnerability and decrease healthcare seeking, and (2) healthcare systems are not structured to promote preventive healthcare for men, particularly BMSM. In fact, they constrained men’s access to primary providers and were usually tailored to women. Applying a structural, gendered lens to men’s health—in addition to the more frequently researched individual or interpersonal levels—provides insight into factors that affect healthcare seeking and HIV prevention for BMSM. These findings have implications for the design of policies and institutional reforms that could enhance the impact of PrEP among BMSM. Findings are also relevant to the management of chronic disease among men more broadly.

Partner Support and Communication for Pre-exposure Prophylaxis (PrEP) Use Among Male Couples

Between one to two-thirds of HIV infections among gay, bisexual, and other men who have sex with men are from primary partners, and there has been increased research attention focused on strategies to increase PrEP adoption among male couples. While there is evidence that partner support is a strong correlate of pre-exposure prophylaxis (PrEP) adoption, there has been a lack of attention on PrEP communication dynamics among male couples. In this paper, we build upon this literature through analysis of dyadic data from a large cross-sectional survey of 543 concordant sero-negative and serodiscordant male couples to examine individual and relationship factors associated with reports of partner communication around PrEP, comfort in discussing PrEP, and perceived partner-level support for PrEP use. PrEP use was relatively low (16.2%), and although 87.5% of men reported their partners would support their PrEP use, only 26.3% had talked to their partner recently about PrEP. PrEP communication and perceived support for PrEP were significantly negatively associated with PrEP stigma and stigma based on sexuality (i.e., internalized homophobia and enacted external stigma based on sexuality), while men with sexual agreements were more comfortable talking about PrEP with their partner. There is a need to adapt current interventions, or develop new dyadic interventions, that provide opportunities for male couples to talk and learn about PrEP together, as a potential pathway to engage them toward PrEP use.

     

Science,technology, power and sex: PrEP and HIV-positive gay men in Paris

Abstract

The pre-exposure prophylaxis (PrEP) drug Truvada is a new HIV prevention technology that is predominantly promoted as relevant to HIV-negative gay men. This paper explores what PrEP represents for HIV-positive gay men living in Paris, based upon data collected through interviews and ethnographic research. While HIV-positive gay men do not directly consume Truvada through PrEP, they nonetheless hold opinions and understandings of this drug, specifically as it relates to their own sexuality. This paper expands the representations and meanings of this new technology in a different light through the voices of gay men living with HIV in Paris. The main argument of this article is that PrEP as an additional HIV prevention tool blurs the lines between science, technologies and human sexuality.     

昆明市男男性行为者对HIV暴露前预防用药的认知、使用意愿及影响因素调查

目的 了解昆明市男男性行为者（MSM）对HIV暴露前预防用药（PrEP）的认知、使用意愿及影响因素,为开展PrEP提供依据。方法 采取定量和定性相结合的方法调查年龄≥16岁、最近1年有过男男肛交性行为、HIV阴性的MSM。定量调查采用非概率“滚雪球”抽样法,内容含人口学特征、个人性行为、PrEP知晓及使用意愿等;定性调查采用立意抽样,了解其对PrEP的看法认知、药物不免费时PrEP的使用意愿、心理期望及HIV预防措施等。结果 有效调查MSM396人,63.9%（253/396）听说过PrEP,如果药物免费,92.4%（366/396）的人有PrEP使用意愿。多因素非条件Logistic回归分析显示：认为自己未来5年内可能会感染HIV（OR=14.192）、不担心PrEP价格（OR=6.023）、听说过PrEP（OR=3.291）、非婚姻关系同居（OR=6.603）是MSM对PrEP使用意愿的独立促进因素。圈内人对PrEP的反对态度（OR=0.015）是MSM对PrEP使用意愿的独立阻碍因素。定性访谈结果显示：11人中,8人听说过PrEP,但其中5人不了解具体是什么;当药物不是免费时,因价格高有不良反应且有效性不是100%,8人表示暂时不会使用;如果未来要使用,愿意支付945.5~1 000元/月。结论 昆明市MSM对PrEP的使用意愿较高,但认知不足,个人风险意识、圈内人的态度、听说过PrEP及价格可能是PrEP使用意愿的影响因素。     

Knowledge and willingness to use pre-exposure prophylaxis among men who have sex with men in Northeastern Brazil

Few studies evaluate knowledge and willingness to use pre-exposure prophylaxis (PrEP) among men who have sex with men (MSM) in middle-income countries. Brazil added PrEP to public drug formularies in December 2017, but little is known about local knowledge and attitudes about PrEP among MSM outside metropolitan areas in Southern Brazil. The cross-sectional HIV Surveillance Survey Project in Brazil estimates HIV and STD prevalence among MSM in 12 state capitals. Among 32 participants at the Salvador, Bahia study site, we used qualitative interviews to assess knowledge, willingness, and barriers to PrEP use among MSM; few MSM had previous knowledge of PrEP and were willing to use PrEP. Clinical, behavioural, social, and structural factors influencing participants’ knowledge and willingness to take PrEP included concerns about efficacy and side effects, access to culturally congruent services for MSM, and stigma. Some participants reported that learning about PrEP online positively influenced their willingness to use PrEP. Participants’ opinions about PrEP’s contribution to risk compensation varied. Interventions to provide culturally congruent care and destigmatise PrEP for MSM at high risk for HIV acquisition, particularly those conducted collaboratively with Brazil’s civil society movement, may enhance the public health effort to expand access to PrEP in Brazil.     

Men having sex with men and the HPV vaccine in France: A low vaccine coverage that may be due to its infrequent proposal by physicians

IntroductionIn France, the human papilloma (HPV) vaccine is recommended to all female adolescents, and since 2016 to men having sex with men (MSM) under the age of 27. Here, we aimed to explore HPV vaccine coverage in adult MSM living in France.MethodsWe elaborated an anonymous online questionnaire targeting MSM and disseminated it between October 7, 2018 and January 15, 2019 by various means, including a Facebook® discussion forum for pre-exposure prophylaxis (PrEP) users.ResultsOverall, 2094 participants completed the questionnaire (mean age 35.4 ± 11 years); 25.8% were in the age class targeted by the HPV vaccine recommendation; 16.1% were in a PrEP program. On a 1–10 scale, they evaluated being “in favor of vaccination” at a median of 10, and general vaccine usefulness and harmfulness at medians of 10 and 2, respectively; 62.4% considered that the HPV vaccine was rather not or not at all dangerous. Those using PrEP had better perceptions of vaccination in general and of the HPV vaccine in particular. For the 1728 participants with a family physician, he/she had proposed the HPV vaccine in 9.9% of cases (9.1% of those in the targeted age class [<27 years]). Overall, 1994 knew their HPV vaccine status; 8.0% had received at least 1 dose of the vaccine, including 17.9% of those in the targeted age class (and 52.2% among the 40 participants in this age group who received PrEP). When the 1935 participants who declared to be unvaccinated against HPV were asked whether they would accept to be vaccinated, 34.4% answered “rather yes” and 45.5% “definitely yes”.ConclusionHPV vaccine coverage is low among French MSM. Our results suggest that this trend has more to do with the infrequent proposals made by clinicians than with negative vaccine perceptions.

Abstract：

Objective To study the acceptability of pre-exposure prophylaxis (PrEP) to prevent the transmission of HIV among men who have sex with men (MSM) in Guangxi, China.Methods Snow-balling methods were used to recruit 650 MSM in Guangxi. Questionnaires and interview were administrated to these 650 men, using a self-designed questionnaire and face to face interviews to collect information on HIV-related risk behaviors, knowledge and acceptability of PrEP.effective, safe and free of charge', 597 (91.9%) of the 650 MSM claimed that they would accept it,who refused to use it, most of them said that were afraid of the side-effect and doubted on the effectiveness of PrEP. Data from logistic regression analysis showed that those who had found partners through friends (OR=6.21, P=0.020) and those who would advise his friend to use PrEP (OR=39.32, P=0.000) were more likely to accept PrEP. Those who thought they could protect themselves from HIV infection (OR=0.32, P=0.010) or not having sex with the ones who refused to use a condom (OR=0.34, P=0.010) were less likely to accept PrEP. Conclusion Effectiveness, safety and cost seemed to be the main influential factors related to the acceptability of PrEP. Peer education might improve the acceptability of PrEP.     

Use of Geosocial Networking Apps and HIV Risk Behavior Among Men Who Have Sex With Men: Case-Crossover Study

BackgroundHIV disproportionately affects men who have sex with men (MSM) in China. The HIV epidemic is largely driven by unprotected anal sex (ie, sex not protected by condoms or HIV pre-exposure prophylaxis [PrEP]). The possible association between unprotected anal sex and the use of geospatial networking apps has been the subject of scientific debate.ObjectiveThis study assessed whether users of a gay geospatial networking app in China were more likely to use condoms when they met their partners online versus offline. A case-crossover analysis, with each person serving as his own control, was employed to address the potential bias that men looking for sex partners through an online dating medium might have inherently different (and riskier) patterns of sexual behavior than men who do not use online dating media.MethodsA cross-sectional survey was administered in 2018 to adult male users of Blued—a gay geospatial networking app—in Beijing, Tianjin, Sichuan, and Yunnan, China. A case-crossover analysis was conducted among 1311 MSM not taking PrEP who reported engaging in both unprotected and protected anal sex in the previous 6 months. Multivariable conditional logistic regression was used to quantify the association between where the partnership was initiated (offline or online) and the act of unprotected anal sex, controlling for other interval-level covariates. Four sensitivity analyses were conducted to assess other potential sources of bias.ResultsWe identified 1311 matched instances where a person reported having both an unprotected anal sex act and a protected anal sex act in the previous 6 months. Of the most recent unprotected anal sex acts, 22.3% (292/1311), were initiated offline. Of the most recent protected anal sex acts, 16.3% (214/1311), were initiated offline. In multivariable analyses, initiating a partnership offline was positively associated with unprotected anal sex (odds ratio 2.66, 95% CI 1.84 to 3.85, P<.001) compared with initiating a partnership online. These results were robust to each of the different sensitivity analyses we conducted.ConclusionsAmong Blued users in 4 Chinese cities, men were less likely to have unprotected anal sex in partnerships that they initiated online compared with those that they initiated offline. The relationship was strong, with over 2.5 times the likelihood of engaging in unprotected anal sex in partnerships initiated offline compared with those initiated online. These findings suggest that geospatial networking apps are a proxy for, and not a cause of, high-risk behaviors for HIV infection; these platforms should be viewed as a useful venue to identify individuals at risk for HIV transmission to allow for targeted service provision.     

‘WTF is PrEP?’: attitudes towards pre-exposure prophylaxis among men who have sex with men and transgender women in New York City

In the USA, gay and other men who have sex with men and transgender women are disproportionately affected by HIV. Uptake of pre-exposure prophylaxis (PrEP), anti-retroviral therapy to prevent HIV-negative individuals from seroconverting if exposed to HIV, by members of this population remains low, particularly among African-Americans. We conducted two focus groups to assess responses to an online social media campaign focusing on PrEP use in New York City. We designed, produced and disseminated the campaign to address knowledge of PrEP; its physical and psychological side effects; and psychosocial barriers related to PrEP adherence and sex shaming. Focus group participants demonstrated a relatively high knowledge of PrEP, although considerable concern remained about side effects, particularly among Black participants. Participants suggested that stigma against PrEP users was declining as PrEP use became more common, but stigma remained, particularly for those not using condoms. Many focus group participants reported distrust of medical providers and were critical of the commodification of HIV prevention by the pharmaceutical industry. Participants reported that those in romantic relationships confronted unique issues regarding PrEP, namely suspicions of infidelity. Finally, Black participants spoke of the need for more tailored and sensitive representations of Black gay men in future programmes and interventions.     

男男性行为者暴露前预防知信行现状及影响因素研究进展

MSM是我国艾滋病感染风险较高的群体,暴露前预防（PrEP）药物是MSM艾滋病防治工作中有效的生物预防策略,可有效降低该人群HIV感染风险。但在实际使用中,PrEP在我国MSM中使用率较低,且存在“知行分离”的现象。本文对国内外MSM的HIV暴露前预防知识知晓、使用意愿及实际使用现状及其影响因素进行综述,为PrEP在我国MSM中的推广应用提供参考。
