Characterizing Awareness of Pre-Exposure Prophylaxis for HIV Prevention in Manila and Cebu, Philippines: Web-Based Survey of Filipino Cisgender Men Who Have Sex With Men.

BACKGROUND: The Philippines is experiencing an HIV crisis and is considering implementing pre-exposure prophylaxis (PrEP) as a national public health strategy for HIV prevention for cisgender men who have sex with men (cis-MSM). However, critical information on the awareness of PrEP among cis-MSM is needed to roll out this public health initiative. OBJECTIVE: This study aims to assess PrEP awareness and related correlates (ie, sociodemographic variables, social factors, and health care access and use) among Filipino cis-MSM. METHODS: We conducted a web-based survey with Filipino cis-MSM (n=179) residing in the cities of Manila and Cebu, Philippines. Multivariable analysis procedures were performed to examine the factors associated with PrEP awareness. RESULTS: Our sample demonstrated high awareness (134/179, 74.9%) and interest (159/179, 88.8%) in taking PrEP. The adjusted model showed that greater odds of PrEP awareness were associated with having a college education or higher versus a high school education or lower (adjusted odds ratio [aOR] 7.30, 95% CI 1.01-52.47), earning between PHP 10,000 (US $198.6) and PHP 20,000 (US $397.2) versus

Violence and Victimization in Interactions Between Male Sex Workers and Male Clients in Mombasa, Kenya.

Male sex workers (MSWs) and male clients (MCMs) who engage their services face increased vulnerability to violence in Kenya, where same-sex practices and sex work are criminalized. However, little is known about how violence might arise in negotiations between MSWs and MCMs. This study explored the types of victimization experienced by MSWs and MCMs, the contexts in which these experiences occurred, and the responses to violence among these groups. We conducted in-depth interviews with 25 MSWs and 11 MCMs recruited at bars and clubs identified by peer sex worker educators as "hotspots" for sex work in Mombasa, Kenya. Violence against MSWs frequently included physical or sexual assault and theft, whereas MCMs' experiences of victimization usually involved theft, extortion, or other forms of economic violence. Explicitly negotiating the price for the sexual exchange before having sex helped avoid conflict and violence. For many participants, guesthouses that were tolerant of same-sex encounters were perceived as safer places for engaging in sex work. MSWs and MCMs rarely reported incidents of violence to the police due to fear of discrimination and arrests by law enforcement agents. Some MSWs fought back against violence enacted by clients or tapped into peer networks to obtain information about potentially violent clients as a strategy for averting conflicts and violence. Our study contributes to the limited literature examining the perspectives of MSWs and MCMs with respect to violence and victimization, showing that both groups are vulnerable to violence and in need of interventions to mitigate violence and protect their health. Future interventions should consider including existing peer networks of MSWs in efforts to prevent violence in the context of sex work. Moreover, decriminalizing same-sex practices and sex work in Kenya may inhibit violence against MSWs and MCMs and provide individuals with safer spaces for engaging in sex work.

"You need money to get high, and that's the easiest and fastest way:" A typology of sex work and health behaviours among people who inject drugs.

BACKGROUND: In the United States, the criminalization and stigmatization of drug use and sex work contribute to infectious disease transmission and healthcare disengagement. People who inject drugs (PWID) and engage in sex work experience exacerbated HIV risk. In the context of the ongoing HIV and overdose epidemics little research describes why PWID engage in sex work and its relative HIV risk. To inform intervention needs, we aimed to create a typology of sex work among PWID with a focus on HIV risk and healthcare utilization behaviours. METHODS: We drew from in-depth interviews conducted across Massachusetts and Rhode Island from 2016-2019. Participants were ≥18 years old and self-reported past-month injection drug use and HIV-negative status. Using data from individuals reporting sex work experience (n=33/78), we utilized the framework method to develop a typology of perspectives on sex work engagement and attributes pertaining to HIV risk and healthcare utilization behaviours. RESULTS: We uncovered varying perspectives on sex work and associated HIV risks and prevention needs. A typology included three groups who viewed their sex work engagement as a (1) consistent job, (2) income supplement, or (3) survival method to abate withdrawal symptoms. The first group described more consistent sexual and injection behaviours to mitigate HIV risk than the second group. The third group appeared particularly vulnerable to HIV, describing inconsistent condom use and frequent sharing of injection equipment, low healthcare utilization, and limited disclosure of sex work and injection drug use to healthcare providers. CONCLUSION: Findings highlight distinct perspectives on sex work among PWID involved in it and corresponding perceptions of HIV risk and healthcare utilization behaviours. Understanding the nuances in sex work engagement among PWID can inform interventions to prevent infectious disease transmission, including efforts to further connect this marginalized population to harm reduction, health, and low barrier opioid treatment services.

Expanding Gender-Based Health Equity Framework for Transgender Populations.

The gender-transformative approach to health promotion in the United States and globally has been central to defining gender as a determinant of health and advancing health programs, services, and policies that respond to gender-based inequities. However, current gender frameworks are built on historical perspectives that center cisgender people's experiences and reinforce the gender binary. This restricted focus does not respond to health inequities experienced by transgender people-to the detriment of health programs, services, and policies. As transgender people's health and rights continue to garner attention in movements across health services and policy spaces, it is crucial for frameworks to be expansively redefined to achieve truly transformative gender equality and equity for all gender identities and expressions.

Psychosocial Problems and Vulnerability to HIV in a Multi-City Prospective Cohort of Young Transgender Women in the United States: A Structural Equation Modeling Study.

BACKGROUND: Gender-based stigma contributes to increased HIV prevalence, but little is known about psychosocial mechanisms linking stigma and HIV risk among young transgender women (YTW). SETTING: This study uses data from Project LifeSkills, a randomized controlled efficacy trial of an empowerment-based HIV prevention intervention for YTW (N = 233). YTW were recruited in Boston, MA, and Chicago, IL, between 2012 and 2015 and completed study assessment visits at baseline and months 4 and 12. METHODS: Using autoregressive structural equation modeling, we examined whether poor social support and psychological distress at 4 months mediate the prospective relationship between gender-based stigma at baseline and condomless anal and vaginal sex (CAVS) acts at 4 and 12 months; all models were adjusted for treatment arm, HIV serostatus, study site, and sociodemographics. RESULTS: Gender-based stigma at baseline was directly associated with increased CAVS at 4 months [adjusted incidence rate ratio (aIRR) = 1.18, 95% confidence interval (CI): (1.05 to 1.33)] and 12 months [aIRR = 1.17, 95% CI: (1.02 to 1.34)]. Gender-based stigma was also associated with higher psychological distress at 4 months [b = 0.70, 95% CI: (0.13 to 1.27)], which in turn was marginally associated with increased CAVS at 12 months [aIRR = 1.03, 95% CI: (1.00 to 1.06)]. Contrary to expectations, poor social support at 4 months was associated with decreased CAVS at 12 months [aIRR = 0.40, 95% CI: (0.28 to 0.59)]. CONCLUSIONS: Future HIV prevention interventions with YTW should consider addressing experiences of gender-based stigma and the psychological distress that may ensue from gender-based stigma. More research is needed to understand the influence of poor social support on sexual behaviors in this population.

Experienced barriers to adherence to pre-exposure prophylaxis for HIV prevention among MSM: a systematic review and meta-ethnography of qualitative studies.

Men who have sex with men (MSM) in the United States are at disproportionate risk for HIV. Once-daily pre-exposure prophylaxis (PrEP) for HIV prevention is a highly effective method of preventing HIV infection; however, optimal adherence is necessary to maintain effectiveness. Many studies have profiled perceived barriers to adherence among at-risk MSM; however, nearly a decade after FDA approval, there has been little work examining experienced barriers to adherence among MSM who have previously used the medication. To assess the current state of this literature and its implications for behavioral interventions, we conducted a meta-ethnography (i.e., A systematic review and synthesis of qualitative studies) of experiences with PrEP use among cis-gender MSM in the United States. We found that structural-level interventions, such as telehealth and pharmacist-prescribed approaches to PrEP distribution, may circumvent barriers to uptake and adherence for some MSM, but may not be enough for already underserved communities, such as MSM of color. Furthermore, interpersonal-level factors, such as enacted PrEP stigma by providers and peers, highlight the necessary consideration of social identity in the branding of PrEP for HIV prevention. Tailored interventions should consider experienced barriers to PrEP adherence across socioecological levels to be most effective.

"Health Is on the Back Burner:" Multilevel Barriers and Facilitators to Primary Care Among People Who Inject Drugs.

BACKGROUND: The estimated 2.2 million people who inject drugs (PWID) in the USA experience significant gaps in preventive healthcare and a high burden of infectious, psychiatric, and other chronic diseases. Many PWID rely on emergency medical services, which are costly and not designed to deliver preventive services, manage chronic conditions, or address social needs. OBJECTIVE: The objective of this study was to explore barriers and facilitators to primary care utilization from the perspectives of PWID in New England, a region highly affected by the overdose crisis. DESIGN: Participants completed semi-structured qualitative interviews exploring substance use and healthcare utilization patterns. PARTICIPANTS: We recruited 78 PWID through community-based organizations (e.g., syringe service programs) in 16 urban and non-urban communities throughout Massachusetts and Rhode Island. APPROACH: Thematic analysis identified barriers and facilitators to primary care utilization at the individual, interpersonal, and systemic levels. KEY RESULTS: Among 78 PWID, 48 described recent primary care experiences; 33 had positive experiences and 15 described negative experiences involving discrimination or mistrust. Individual-level barriers to primary care utilization included perceived lack of need and competing priorities (e.g., avoiding opioid withdrawal, securing shelter beds). Interpersonal-level barriers included stigma and perceived low quality of care for PWID. Systemic-level barriers included difficulty navigating healthcare systems, inadequate transportation, long wait times, and frequent provider turnover. Participants with positive primary care experiences explained how appointment reminders, flexible hours, addiction medicine-trained providers, case management services, and transportation support facilitated primary care utilization and satisfaction. CONCLUSIONS: Findings regarding the multilevel barriers and facilitators to accessing primary care among PWID identify potential targets for programmatic interventions to improve primary care utilization in this population. Based on these findings, we make recommendations for improving the engagement of PWID in primary care as a means to advance individual and public health outcomes.

Transactional Sex Is Associated with Income Level and Psychosocial Health Problems among Gay and Bisexual Men (GBM) in Nigeria, Africa.

Gay and bisexual men (GBM) who report engagement in transactional sex are at increased risk for HIV acquisition. The current study aimed to assess the prevalence of transactional sex and its association with demographic characteristics, social marginalization, HIV sexual risk behaviors, psychosocial health problems, and access to healthcare services among a multi-site sample of GBM in Nigeria. Bivariate and multivariable logistic regression were used to examine factors associated with engagement in transactional sex in the previous 3 months. More than a third (39.6%) of the participants reported engagement in transactional sex in the previous 3 months. In the multivariable model, factors associated with engagement in transactional sex included: reporting a monthly income of 30,000 Naira [adjusted odds ratio (aOR) 1.98; 95% CI: 1.12 to 3.35], compared to 30,000 or more Naira monthly income, reporting 4 or more receptive anal sex acts in the previous 30 days (aOR 2.45; 95% CI: 1.31 to 4.57) compared to reporting none, and having depressive symptoms (aOR 1.82; 95% CI: 1.06 to 3.14). There is an urgent need for interventions that address the economic disenfranchisement and psychosocial problems experienced by GBM in Nigeria, which has implications for sexual health.

Sexual orientation and social network size moderate associations between stigma and problematic alcohol use among male sex workers in the US Northeast: an observational study.

Background Stigma is associated with poor health among sexual minority individuals. However, no studies have examined the relationship between stigma and problematic drinking among male sex workers (MSWs). This study examined the relationship between sex work stigma and problematic alcohol use among MSWs. METHODS: Using baseline data from a cohort of 98 MSWs in the US Northeast enrolled between 2015 and 2016, we used logistic regression to examine associations between sex work stigma and hazardous drinking (Alcohol Use Disorders Identification Test (AUDIT) score ≥8) and sex work while drunk, and tested whether sexual orientation (gay vs non-gay identified) and social network size moderated these associations. RESULTS: Almost half the sample (n = 46; 44%) reported hazardous drinking and 56 MSWs (57%) reported engaging in sex work while drunk. Sex work stigma was associated with hazardous drinking (adjusted odds ratio (aOR) 1.2, 95% confidence interval (CI) 1.05-1.36). Sexual orientation marginally moderated this relationship (P = 0.07), such that it was only significant among gay-identified MSWs (aOR 1.91, 95% CI 1.11-3.28), not among non-gay MSW. Similarly, sexual orientation moderated the effect of sex work stigma on sex work while drunk (P = 0.02), which was only significant among gay-identified MSWs (aOR 1.65, 95% CI 1.05-1.60). Social network size also moderated the effect of sex work stigma on sex work while drunk (P = 0.02), which was only significant among MSWs with small networks (aOR 1.26, 95% CI 1.00-1.58), suggesting large networks can be protective. CONCLUSIONS: Gay MSWs may be particularly vulnerable to alcohol-related effects of stigma. Future interventions should consider engaging social networks to curb problematic drinking among MSWs.

Poor sleep health is associated with increased mental health problems, substance use, and HIV sexual risk behavior in a large, multistate sample of gay, bisexual and other men who have sex with men (GBMSM) in Nigeria, Africa.

BACKGROUND: Poor sleep health has been linked to mental health problems, substance use, and sexual risk-taking among gay, bisexual, and other men who have sex with men (GBMSM). No known published study has examined these relationships among African GBMSM. Consequently, we investigated poor sleep health and associated health-related factors among a large multistate sample of Nigerian GBMSM. METHODS: Between March and June 2019, 406 GBMSM were recruited from Abuja, Delta, Lagos, and Plateau and asked to complete an interviewer-administered survey. Bivariate and multivariable logistic regression models were constructed to examine the relationship between poor sleep health and other health-related factors. RESULTS: In the past month, 45.5% of participants reported sleeping an average of 6 hours or less every night, and 30.7% reported experiencing a sleep problem. Factors associated with increased odds of reporting short sleep included: residing in Delta [adjusted odds ratio (aOR) 2.16; 95% confidence interval (CI): 1.15 to 4.04] and Lagos (aOR 2.40; 95% CI: 1.29 to 4.45), depressive symptoms (aOR 1.94; 95% CI: 1.13 to 3.32), and reporting lifetime history of using four or more drugs (aOR 2.52; 95% CI: 1.06 to 6.01). Reporting condom use at last anal sex was associated with decreased odds of reporting short sleep in the last month (aOR 0.54; 95% CI: 0.31 to 0.92). Factors associated with increased odds of reporting sleep problems included: reporting an STI diagnosis in the last year (aOR 1.79; 95% CI: 1.05 to 3.05) and reporting monthly or higher polydrug use in the last 3 months (aOR 2.19; 95% CI: 1.14 to 4.24). DISCUSSION: Sleep health interventions should be developed for Nigerian GBMSM, which may improve mental health and reduce substance use and sexual risk-taking.

Network-Level Correlates of Sexual Risk Among Male Sex Workers in the United States: A Dyadic Analysis.

BACKGROUND: Male sex workers (MSWs) are at increased risk of HIV infection in the United States. Research is limited on sexual and drug use network characteristics of MSWs. SETTING: Community-based organization and health center in 2 US Northeast cities. METHODS: One hundred MSWs completed a behavioral assessment and sexual and drug network inventory. Using dyadic analyses, we assessed whether network characteristics, including sex worker-male client age, race, and HIV status homophily and risk multiplexity (ie, overlap in drug-use and sex networks), were associated with condom use. RESULTS: MSW participants' mean age was 33.6. Two-thirds identified as Black or Latino, 12% identified as heterosexual, and 90% reported recent drug use. Participants reported an average of 5.3 male clients in the past month (SD = 3.4), and having anal sex with 74% of these clients, at a rate of 2.2 times per month (SD = 4.6). Participants reported inconsistent condom use during anal sex with 53% of clients. In multivariable models, inconsistent condom use was more common in relationships with presumed HIV status homophily [odds ratio (OR): 1.25; 95% confidence interval (CI): 1.07 to 1.46] and sexual and drug network multiplexity (OR: 1.19; 95% CI: 1.09 to 1.30); and less common within relationships where the client is older than the MSW participant (OR: 0.83; 95% CI: 0.74 to 0.93). Number of multiplex relationships was positively associated with number of condomless anal sex acts with male clients (incidence rate ratio: 1.35; 95% CI: 1.19 to 1.54). CONCLUSIONS: Network characteristics may contribute to disproportionate HIV risk among MSWs. Modeling studies should include network characteristics when simulating HIV transmission, and future HIV interventions should address the role of networks.

HIV Pre-exposure Prophylaxis for People Who Inject Drugs: The Context of Co-occurring Injection- and Sexual-Related HIV Risk in the U.S. Northeast.

Background: People who inject drugs (PWID) are at increased risk for HIV infection through sharing contaminated needles and injection equipment, and engaging in condomless sex. Objectives: To qualitatively examine the overlapping nature of these behaviors among PWID in the US Northeast. Methods: We recruited HIV-uninfected PWID and key informants through community-based organizations. Qualitative interviews explored sexual partnerships as they related to sharing contaminated needles and injection equipment, engaging in condomless sex, and associated indications for PrEP among PWID. Results: Among 33 PWID, 66% engaged in condomless vaginal or anal sex in the past 3 months, and 27% had three or more sexual partners in this same time period. Over half engaged in any past month distributive or receptive syringe sharing (64%). We identified three contexts through which overlapping sexual and injection-related HIV risks emerged, including (1) multiple concurrent sexual partnerships; (2) using and injecting drugs with sexual partners (including increase injecting of crystal methamphetamine); and (3) exchanging sex for money or drugs (including among male PWID). Condom use was inconsistent across these contexts. Limited interactions with healthcare providers often resulted in sexual risks being overlooked in light of competing health concerns. Conclusions: Sexual risk for HIV acquisition is complex and multi-faceted among PWID yet may be overlooked by prevention and healthcare providers. Comprehensive HIV prevention efforts must acknowledge the distinct contexts in which overlapping injection and sexual risk behaviors occur. Increased sexual health screening and risk reduction services including PrEP for PWID may help curtail transmission in this population.

"I Do Try To Use Condoms, But ": Knowledge and Interest in PrEP Among Male Sex Workers in Mexico City.

In Mexico City, male sex workers (MSWs) are up to 126 times more likely to be living with HIV than the general public. We conducted interviews with 23 MSWs in Mexico City to examine their subjective understandings about their sexual risk behaviors and explore opportunities about HIV pre-exposure prophylaxis (PrEP) as a prevention approach in this group. Despite knowledge about sexual HIV risks, most participants reported condomless anal sex with clients. There was very little prior knowledge about PrEP, but very high interest in using a daily pill for prevention. Several participants expected an increase in condomless anal sex if taking PrEP, because of monetary incentives from clients or a perceived increase in pleasure. Additionally, seasonal sex workers expressed interest in using PrEP only during months when they were performing sex work. PrEP implementation efforts through Mexico's healthcare system should recognize the varying needs and sexual risk behaviors of MSWs.

"We don't get much of a voice about anything": perspectives on photovoice among people who inject drugs.

BACKGROUND: In the context of the current US opioid crisis, people who inject drugs (PWID) are increasingly researched, but their ability to tell their own stories may be limited. Photovoice is a participatory action research method that allows participants to use photography to directly depict their experiences. METHODS: We conducted interviews with PWID (n = 33) as part of a qualitative study on the health needs of PWID in the USA to explore interest and acceptability of photovoice as a potential research method and way to share their voices. RESULTS: Participants identified facilitators and barriers to participating in a future photovoice project. Facilitators included a chance to depict one's unique experience, help others in need by sharing one's own story, and photography being a more "comfortable" way to tell their stories than traditional research methods. Barriers included safety concerns, embarrassment, and ability to retain cameras. Participants also identified areas of sensitivity related to documenting drug use. CONCLUSIONS: While we found broad acceptability of photovoice, barriers would need to be addressed and additional training and support for research staff and potential participants related to the ethics of public photography and engaging PWID in photovoice research would be required.

The HIV-Related Risk Factors of the Cisgender Male Sexual Partners of Transgender Women (MSTW) in the United States: A Systematic Review of the Literature.

Cisgender male sexual partners of transgender women (MSTW) may be at risk for HIV infection. We performed a review of HIV risk factors among MSTW. We searched PubMed database for empirical quantitative U.S.-based studies that included MSTW and were published in English up to November 2018. Of the 4,680 total papers identified, 6 unique studies were included. MSTW displayed heterogeneity in HIV risk factors (e.g., condom use, sexual partners, sexual positions, substance use). In our exploratory meta-analyses, estimated prevalence of self-reported HIV positive status among MSTW was 30.6%, HIV unknown status was 8.8%, and self-reported condomless anal sex with transgender women was 46.1%. Reports of sexual health communication with transgender women was low. More research on MSTW populations is needed to better understand this population's unique needs in the context of recent advancements in HIV prevention.

Strategies used by people who inject drugs to avoid stigma in healthcare settings.

BACKGROUND: People who inject drugs (PWID) have limited engagement in healthcare services and report frequent experiences of stigma and mistreatment when accessing services. This paper explores the impact of stigma against injection drug use on healthcare utilization among PWID in the U.S. Northeast. METHODS: We recruited PWID through community-based organizations (CBOs; e.g., syringe service programs). Participants completed brief surveys and semi-structured interviews lasting approximately 45 min exploring HIV risk behaviors and prevention needs. Thematic analysis examined the emergent topic of stigma experiences in relation to healthcare utilization. RESULTS: Among 33 PWID (55% male; age range 24-62 years; 67% White; 24% Latino), most used heroin (94%) and injected at least daily (60%). Experiences of dehumanization in healthcare settings were common, with many participants perceiving that they had been treated unfairly or discriminated against due to their injection drug use. As participants anticipated this type of stigma from healthcare providers, they developed strategies to avoid it, including delaying presenting for healthcare, not disclosing drug use, downplaying pain, and seeking care elsewhere. In contrast to large institutional healthcare settings, participants described non-stigmatizing environments within CBOs, where they experienced greater acceptance, mutual respect, and stronger connections with staff. CONCLUSIONS: Stigma against injection drug use carries important implications for PWID health. Increased provider training on addiction as a medical disorder could improve PWID healthcare experiences, and integrating health services into organizations frequented by PWID could increase utilization of health services by this population.

Development of a Social Network-Based Intervention to Overcome Multilevel Barriers to ART Adherence Among Adolescents in Brazil.

Brazil's comprehensive HIV treatment program does not specifically address ART adherence challenges for adolescents-a group accounting for the largest number of incident HIV infections in Brazil. We conducted three focus groups with 24 adolescents (age 15-24) living with HIV in Rio de Janeiro, separately for cisgender men who have sex with men, heterosexual-identified cisgender men and women, and transgender women of any sexual orientation, and key informant interviews (n = 7) with infectious disease specialists and HIV/AIDS service organization staff. Content analysis identified socioecological barriers and facilitators to adherence, including individual (e.g., low knowledge, side effects, and substance use), interpersonal (e.g., stigma from partners and health care providers) and structural (e.g., transportation and medication access) barriers. Overlapping and unique barriers emerged by sexual/gender identity. A community-informed, theory-driven ART adherence intervention for adolescents that is organized around identity and leverages social networks has the potential to improve HIV treatment and health outcomes for Brazilian adolescents.

Evidence-based and guideline-concurrent responses to narratives deferring HCV treatment among people who inject drugs.

BACKGROUND: Hepatitis C virus (HCV) infection is increasingly prevalent among people who inject drugs (PWID) in the context of the current US opioid crisis. Although curative therapy is available and recommended as a public health strategy, few PWID have been treated. We explore PWID narratives that explain why they have not sought HCV treatment or decided against starting it. We then compare these narratives to evidence-based and guideline-concordant information to better enable health, social service, harm reduction providers, PWID, and other stakeholders to dispel misconceptions and improve HCV treatment uptake in this vulnerable population. METHODS: We recruited HIV-uninfected PWID (n = 33) through community-based organizations (CBOs) to participate in semi-structured, in-depth qualitative interviews on topics related to overall health, access to care, and knowledge and interest in specific HIV prevention methods. RESULTS: In interviews, HCV transmission and delaying or forgoing HCV treatment emerged as important themes. We identified three predominant narratives relating to delaying or deferring HCV treatment among PWID: (1) lacking concern about HCV being serious or urgent enough to require treatment, (2) recognizing the importance of treatment but nevertheless deciding to delay treatment, and (3) perceiving that clinicians and insurance companies recommend that patients who currently use or inject drugs should delay treatment. CONCLUSIONS: Our findings highlight persistent beliefs among PWID that hinder HCV treatment utilization. Given the strong evidence that treatment improves individual health regardless of substance use status while also decreasing HCV transmission in the population, efforts are urgently needed to counter the predominant narratives identified in our study. We provide evidence-based, guideline-adherent information that counters the identified narratives in order to help individuals working with PWID to motivate and facilitate treatment access and uptake. An important strategy to improve HCV treatment initiation among PWID could involve disseminating guideline-concordant counternarratives to PWID and the providers who work with and are trusted by this population.

The role of sexual risk behaviors on PrEP awareness and interest among men who have sex with men in Latin America.

In Latin America, men who have sex with men (MSM) remain disproportionately impacted by HIV. Pre-exposure prophylaxis (PrEP) is an effective HIV prevention tool and has been FDA approved in the United States since 2012, but no Latin American state, with the recent exception of Brazil, has implemented PrEP guidelines. We carried out a multinational online survey of MSM in Latin America (n = 22698) in 2012 to assess whether MSM at highest risk of HIV acquisition (i.e., those engaging in condomless anal sex [CAS; n = 2606] and transactional sex [n = 1488]) had higher levels of awareness of PrEP, PrEP use and interest in participating in a PrEP trial. After adjusting for demographic and psychosocial characteristics including depressive symptoms, hazardous alcohol use, childhood sexual abuse, and sexual compulsivity, transactional sex and CAS were associated with increased PrEP awareness (aOR = 1.29, 95% CI: 1.05-1.59, p < .001 and aOR = 1.22, 95% CI: 1.11-1.34, p < .001, respectively) and PrEP trial interest (aOR = 1.45, 95% CI: 1.25-1.71, p < .001 and aOR = 1.74, 95% CI: 1.57-1.95, p < .001, respectively). Findings demonstrate substantial awareness of and interest in PrEP among MSM with behavioral risk factors for HIV in Latin America, suggesting that this region is primed for PrEP implementation, which has been slow.

Risk Perception and Interest in HIV Pre-exposure Prophylaxis Among Men Who Have Sex with Men with Rectal Gonorrhea and Chlamydia Infection.

Rectal gonorrhea and chlamydia infections are associated with significantly increased risk of HIV transmission among gay, bisexual, and other men who have sex with men (MSM). MSM diagnosed with rectal gonorrhea or chlamydia may benefit from pre-exposure prophylaxis (PrEP) for HIV prevention. We analyzed HIV risk perception, PrEP interest, and sexually transmitted infection (STI) test results among MSM presenting to a publicly funded STI clinic from 2014 to 2016. A total of 401 MSM were tested for rectal STIs during the study period: 18% were diagnosed with rectal gonorrhea or chlamydia infection. Patients who perceived themselves to be at medium or high risk for HIV were significantly more likely to express interest in PrEP compared to those who reported low or no perceived risk (OR 1.88, 95% CI 1.13-3.11; p = .014). However, there was no significant difference in perceived HIV risk between those who were diagnosed with a rectal STI and those who were not. Although rectal STIs are a significant risk factor for HIV infection, MSM diagnosed with a rectal STI did not perceive themselves to be at increased risk for HIV infection, indicating a potential barrier to successful PrEP implementation in this population.
