The Moderating Effects of HIV Relevant Factors on the Relationship Between Intimate Partner Violence and Intention to Start HIV Pre-exposure Prophylaxis (PrEP) Among Cisgender Women.

Intimate partner violence (IPV) and HIV are serious and related public health problems that detrimentally impact women's health. Because women who experience IPV are more likely to acquire HIV, it is critical to promote HIV prevention strategies, such as HIV pre-exposure prophylaxis (PrEP), that increase autonomy. This study of cisgender women eligible for HIV PrEP took place between 2017 and 2019 in Philadelphia and New York City. This study aimed to examine the relationship between four types of IPV (control, psychological, physical, sexual) and intention to start PrEP among PrEP-eligible cisgender women and assess the extent to which HIV relevant factors moderated the association between IPV experience and intention to start PrEP. In this sample of PrEP-eligible women (n = 214), 68.7% indicated intention to start PrEP in the next 3 months. Ethnicity was strongly associated with intention to start PrEP, with Hispanic women having the highest odds of intending to start PrEP in the next 3 months. Having a controlling partner significantly predicted intention to start PrEP. Women with more than one sex partner and a controlling partner had higher odds of intending to start PrEP as compared with those who had one or no partners and had no IPV control. These findings point to a need for patient-centered interventions that address the need for safety and autonomy among cisgender, PrEP-eligible women.

HIV risk perception, pre-exposure prophylaxis (PrEP) awareness, and PrEP initiation intention among women who use drugs.

INTRODUCTION: Women who use drugs (WWUD) are prime candidates for pre-exposure prophylaxis (PrEP) due to their elevated risk of acquiring HIV through biological, behavioral, and contextual factors. However, PrEP uptake among WWUD remains low. The relationship between unhealthy drug use and correlates of PrEP uptake in this vulnerable population is not well defined. The purpose of this study is to characterize the relationships between specific types and routes of drug use and several precursors of PrEP uptake among WWUD. METHODS: The study collected data via a computer-based survey from 233 women living in New York City and Philadelphia who participated in a study designed to develop and pilot a women-focused intervention for PrEP uptake. The sample of cisgender, HIV-negative women were not currently taking PrEP but considered PrEP eligible. This analysis is focused on women's HIV risk perception, PrEP awareness, PrEP initiation intention, and any use of the following drugs: barbiturates, benzodiazepines, crack cocaine, powder cocaine, hallucinogens, heroin, methamphetamines, and prescription opioids. RESULTS: Within the three months prior to study enrollment, 63.1 % of participants reported any drug use; 42 % reported polydrug use; 19.8 % had injected drugs; 75 % reported getting high or drunk before sex; and 44 % had been enrolled in drug treatment. Of our total sample, 41.2 % perceived themselves at risk for HIV infection, 41.6 % were aware of PrEP prior to the study, and 62.7 % intended to initiate PrEP after they were informed. When compared to other PrEP-eligible women, women who reported prescription opioid use and polydrug use perceived themselves at higher risk for HIV infection and had higher intention to start PrEP. However, they and women who reported injecting drugs also reported lower awareness of PrEP. CONCLUSION: These findings have implications for increasing education about PrEP and the various modes of HIV exposure to support PrEP uptake in this vulnerable population.

A Randomized Controlled Pilot Study of Just4Us, a Counseling and Navigation Intervention to Promote Oral HIV Prophylaxis Uptake Among PrEP-Eligible Cisgender Women.

HIV pre-exposure prophylaxis (PrEP) uptake among cisgender women in the United States is low. Just4Us, a theory-based counseling and navigation intervention, was evaluated in a pilot randomized controlled trial among PrEP-eligible women (n = 83). The comparison arm was a brief information session. Women completed surveys at baseline, post-intervention, and at three months. In this sample, 79% were Black, and 26% were Latina. This report presents results on preliminary efficacy. At 3 months follow-up, 45% made an appointment to see a provider about PrEP; only 13% received a PrEP prescription. There were no differences in PrEP initiation by study arm (9% Info vs. 11% Just4Us). PrEP knowledge was significantly higher in the Just4Us group at post-intervention. Analysis revealed high PrEP interest with many personal and structural barriers along the PrEP continuum. Just4Us is a promising PrEP uptake intervention for cisgender women. Further research is needed to tailor intervention strategies to multilevel barriers.Clinicaltrials.gov registration NCT03699722: A Women-Focused PrEP Intervention (Just4Us).

RESUMEN: La aceptación de la profilaxis previa a la exposición (PrEP) al VIH entre las mujeres cisgénero en los Estados Unidos es baja. Just4Us, una intervención de asesoramiento y navegación basada en la teoría, se evaluó en un ensayo piloto controlado aleatorizado con mujeres aptas para la PrEP (n = 83). El brazo de comparación fue una breve sesión de información. Las mujeres completaron encuestas al inicio, después de la intervención ya los 3 meses. En la muestra, el 79% eran negros y el 26% eran latinas. Este informe presenta resultados sobre la eficacia preliminar. A los 3 meses de seguimiento, el 45% hizo una cita para ver a un proveedor acerca de la PrEP; solo el 13% recibió una receta de PrEP. No hubo diferencias en el inicio de la PrEP por brazo de estudio (9% Info frente a 11% Just4Us). El conocimiento fue significativamente mayor en el grupo Just4Us después de la intervención. El análisis reveló un alto interés por la PrEP con muchas barreras personales y estructurales a lo largo del continuo de la PrEP. Just4Us es una prometedora intervención de adopción de PrEP para mujeres cisgénero. Se necesita más investigación para adaptar las estrategias de intervención a las barreras multinivel.

Women's views on communication with health care providers about pre-exposure prophylaxis (PrEP) for HIV prevention.

Since the beginning of the HIV epidemic in the USA, effective interventions to reduce HIV risk among cisgender women have been lacking. Although oral HIV pre-exposure prophylaxis (PrEP) is effective in pharmacologically preventing HIV infection, there is a gap between the recommended use of PrEP and PrEP uptake among eligible women. This study aimed to identify the role of patient-provider communication in PrEP decision-making among women considering PrEP. Semi-structured in-depth interviews were conducted with 41 PrEP-eligible women in Philadelphia and New York City. A thematic analysis of the responses was conducted, and a conceptual model developed and confirmed as analysis continued. Of the women interviewed, 53.6% were African American and 29.3% were Latina. Women noted that having a trusting relationship with their health care provider, receiving a tailored recommendation for PrEP based upon their specific needs and using their health care provider as support were crucial facilitators of PrEP decision-making. Lack of provider knowledge about PrEP, perceived health care provider stigma about their drug use and sexual activity, and lack of care continuity were all identified as barriers to effective communication. Study findings can inform future interventions to enhance patient-provider communication about PrEP and increase PrEP uptake among women.

Individual, social and structural factors influencing PrEP uptake among cisgender women: a theory-informed elicitation study.

The underutilization of pre-exposure prophylaxis (PrEP) among cisgender women in the U.S. limits this population's ability to reduce their risk for HIV infection, especially within the unique individual, social and structural systems they navigate. There is a need to identify the relevant multi-level barriers and facilitators to PrEP use among cisgender women to inform theory-guided efforts that address HIV disparities by race/ethnicity among cisgender women. Guided by the Integrated Behavioral Model and the Behavioral Model of Vulnerble Populations we conducted 41 interviews with PrEP eligible cisgender women in New York City and Philadelphia. Directed content analysis identified 11 modal behavioral beliefs crucial to PrEP uptake, including anticipated negative social consequences, 5 normative beliefs centered on available social supports, and 9 control beliefs such as anticipated barriers such as cost. Awareness and knowledge of PrEP as a biobehavioral HIV prevention method is limited for this sample. Through conventional content analysis we identified interpersonal and structural barriers to PrEP uptake including lack of partner support, transportation, mental health challenges, and challenges in accessing PrEP care. Potential solutions to structural barriers were enumerated along with implications for future intervention work and public health programming.

Just4Us: Development of a Counselor-Navigator and Text Message Intervention to Promote PrEP Uptake Among Cisgender Women at Elevated Risk for HIV.

ABSTRACT: In the United States, pre-exposure prophylaxis (PrEP) uptake among eligible cisgender women has been slow, despite the availability of oral PrEP since 2012. Although women make up nearly 20% of those living with HIV, there are currently few PrEP uptake interventions for cisgender women at elevated risk for acquiring HIV. Here we describe the process used to design and pre-pilot test Just4Us, a theory-based behavioral intervention to promote PrEP initiation and adherence among PrEP-eligible cisgender women. This work was part of a multiphase study conducted in New York City and Philadelphia, two locations with HIV rates higher than the national average. The counselor-navigator component of the intervention was designed to be delivered in a 60- to 90-min in-person session in the community, followed by several phone calls to support linkage to care. An automated text messaging program was also designed for adherence support. Just4Us addressed personal and structural barriers to PrEP uptake using an empowerment framework by building on women's insights and resources to overcome barriers along the PrEP cascade. Usability pre-pilot testing results were favorable and provided valuable feedback used to refine the intervention.

PrEP Stigma, HIV Stigma, and Intention to Use PrEP among Women in New York City and Philadelphia.

BACKGROUND: Stigma is an important contributor to the continued HIV epidemic in the United States (US). In 2016, women made up nearly one in five of all new infections. Pre-exposure HIV Prophylaxis or PrEP is a medication that can be taken to prevent HIV acquisition; however, PrEP is significantly underutilized by women at risk for infection. How PrEP stigma relates to PrEP initiation among women is not well understood. METHODS: Surveys were completed by 160 PrEP-eligible women aged 18-55 in Philadelphia, PA and New York City, NY. Associations between PrEP stigma, HIV stigma, and PrEP initiation intention were modeled using multinomial logistic regression, controlling for sociodemographic and theoretically-relevant variables. RESULTS: Participants ranged in age from 18 to 55 years (M = 40.2; SD = 11.78). Most (79%) identified as Black or African-American and/or Latina and 36% had completed high-school or less. Higher PrEP stigma was significantly associated with lower PrEP initiation intention, while controlling for other theoretically-relevant and sociodemographic variables. HIV stigma was not related to PrEP initiation intention. CONCLUSIONS: HIV prevention interventions seeking to increase PrEP initiation among PrEP-eligible, urban women need to address the role that PrEP stigma plays in PrEP uptake.

Beliefs Associated with Intention to Use PrEP Among Cisgender U.S. Women at Elevated HIV Risk.

Women comprise 19% of those newly diagnosed with HIV in the U.S. There is a wide gap between recommended use of pre-exposure prophylaxis (PrEP) and actual uptake among women who are eligible for PrEP. In order to identify women's beliefs and intentions about starting PrEP, a survey, informed by the reasoned action approach, was administered to 160 cisgender PrEP-eligible women, age 18-55, in Philadelphia and New York City. The mean age was 40.2 years (SD = 11.78), 44% had completed high school, 75% were unemployed, and 85% experienced financial instability in the past 3 months. Multivariate linear regression analyses identified sets of behavioral and normative beliefs associated with intention to start PrEP in the next 3 months. Behavioral beliefs reflected views about PrEP benefits such as preventing HIV, and normative beliefs reflected perceptions of support or lack thereof from others including partners, friends, mother, and children. These findings can be used to inform interventions to foster greater PrEP uptake among women.

Who is Using the HIV Self-Test among Young Black Men Who Have Sex With Men (MSM) and Transwomen in New York City?

BACKGROUND: HIV self-testing (HST) is an important complement to existing testing approaches for young Black men who have sex with men (MSM) and transwomen. METHODS: In this formative research, we describe prevalence and perceptions of HST using qualitative in-depth interviews (n = 29) and baseline quantitative data (n = 302) from an HST intervention trial for young Black MSM and transwomen. RESULTS: In the qualitative analysis, participants preferred the privacy and flexibility of the HST but had concerns about its accuracy and being alone while testing. Quantitative results showed that 14% (44/302) had used an HST in their lifetime; of these, 64% (28/44) used it once and 23% (10/44) in the last 3 months. CONCLUSION: To increase consistent testing, HST may provide a new avenue for at-risk individuals that value privacy and control and could benefit from social support during testing.

The Role of Social Support in HIV Testing and PrEP Awareness among Young Black Men and Transgender Women Who Have Sex with Men or Transgender Women.

Young black men and transgender women (transwomen) who have sex with men or transwomen are most vulnerable in terms of risk for HIV infection, also reflected in their extremely high incidence rates. As testing rates and pre-exposure prophylaxis (PrEP) uptake remain suboptimal among these groups, primarily due to unique structural barriers, the present analyses draw on data from an online survey, administered October 2014 to August 2015, to explore social support-related predictors of knowledge and behavior around HIV prevention.Participants were 169 biological men who identified as black, with a mean age of 24 (SD = 2.97, range 17-29); 8% identified as transwomen. Logistic regression models assessed whether HIV-related social support predicted HIV testing patterns, PrEP awareness, and use. Those with higher HIV-related social support reported having been more likely to have ever tested (adjusted odds ratio (aOR) = 1.48; p < 0.001) and tested in the past 6 months (aOR = 1.22; p < 0.01). They were also more likely to intend to test in the next 6 months (aOR = 1.16; p < 0.001), including at a medical office or community-based organization (aOR = 1.20; p < 0.001), yet less likely to intend to self-test (aOR = 0.81; p < 0.001). Lastly, higher social support was significantly associated with prior knowledge of self-testing (aOR = 1.19; p < 0.05), couples testing (aOR = 1.26; p < 0.001), and PrEP (aOR = 1.22; p < 0.01), as well as prevention self-efficacy (aOR = 1.30; p < 0.001), but inversely associated with prior self-testing (aOR = 0.80; p < 0.05). For young black men and transwomen who have sex with men or transwomen, HIV-related social support, which likely has a strong peer component, appears to be a facilitator of optimal testing and intentions to test, as well as awareness of novel prevention strategies (like self-testing or PrEP). However, community resourcefulness needs to be bolstered by other mechanisms, such as changes within healthcare settings, to increase actual use of novel prevention modalities.

Development and Validation of the Personalized Sexual Health Promotion (SexPro) HIV Risk Prediction Model for Men Who Have Sex with Men in the United States.

Accurate HIV risk assessment among men who have sex with men (MSM) is important to help providers assess risk, and target HIV prevention interventions. We sought to develop an evidence-based HIV risk assessment tool for US MSM that is inclusive of Black MSM. Data from four large longitudinal cohorts of MSM were used to develop (EXPLORE), and validate (VAX004, HPTN061, and HVTN505). These data included visits in which participants self-reported HIV risk behavior and underwent HIV testing. We developed a pooled logistic model for incident HIV infection based on self-reported risk behaviors during the 6 months before each study visit. A total of 4069 MSM were used for the development cohort, and 8047 MSM in the three validation cohorts through 2013. The final model includes age (< 35, ≥ 35); Black race and Latino ethnicity; numbers of HIV-negative anal sex partners; number of insertive or receptive anal intercourse episodes; having 1 HIV-negative partner only; self-reported substance use; and bacterial sexually transmitted infection diagnosis. The model showed good discrimination in internal validation (C-statistic = 79.5). The external validation cohorts also showed good discrimination, with C-statistics of 73.1, 71.0, 71.9 in VAX004, HPTN061, and HVTN505 respectively, and acceptable calibration. We developed and validated an HIV risk assessment tool for MSM, which showed good predictive ability, including among the largest cohort of HIV-uninfected Black MSM in the US. This tool is available online (mysexpro.org) and can be used by providers to support targeting of HIV prevention interventions such as pre-exposure prophylaxis for MSM.

Neighborhood and Network Characteristics and the HIV Care Continuum among Gay, Bisexual, and Other Men Who Have Sex with Men.

In order for treatment as prevention to work as a national strategy to contain the HIV/AIDS epidemic in the United States (US), the HIV care continuum must become more robust, retaining more individuals at each step. The majority of people living with HIV/AIDS (PLWHA) in the US are gay, bisexual, and other men who have sex with men (MSM). Within this population, there are distinct race- and ethnicity-based disparities in rates of HIV infection, engagement, and retention in HIV care, and viral suppression. Compared with White MSM, HIV-infected Black MSM are less likely to be on anti-retroviral therapy (ART), adhere to ART, and achieve viral suppression. Among MSM living in urban areas, falling off the continuum may be influenced by factors beyond the individual level, with new research identifying key roles for network- and neighborhood-level characteristics. To inform multi-level and multi-component interventions, particularly to support Black MSM living in urban areas, a clearer understanding of the pathways of influence among factors at various levels of the social ecology is required. Here, we review and apply the empirical literature and relevant theoretical perspectives to develop a series of potential pathways of influence that may be further evaluated. Results of research based on these pathways may provide insights into the design of interventions, urban planning efforts, and assessments of program implementation, resulting in increased retention in care, ART adherence, and viral suppression among urban-dwelling, HIV-infected MSM.

Brief Report: Randomized Controlled Trial of an Intervention to Match Young Black Men and Transwomen Who Have Sex With Men or Transwomen to HIV Testing Options in New York City (All About Me).

BACKGROUND: HIV testing is critical to HIV prevention and care. Infrequent HIV testing and late HIV diagnosis have been observed among young Black men who have sex with men and transwomen. Novel interventions to increase HIV testing rates among young Black men who have sex with men and transwomen are needed. METHODS: A randomized controlled trial among 236 young Black men and transwomen who have sex with men or transwomen evaluated the efficacy of an intervention that included completion of a brief survey and receipt of a personalized recommendation of an optimal HIV testing approach. Participants completed a computerized baseline assessment and were randomized to electronically receive either a personalized recommendation or standard HIV testing information. Follow-up surveys were conducted online at 3 and 6 months. RESULTS: Retention was 92% and 93% at 3-month and 6-month follow-up, respectively. At baseline, 41% of participants reported that they tested for HIV in the past 3 months and another 25% between 4 and 6 months ago. Intent-to-treat analyses found that participants randomized to the experimental arm (personalized recommendation) were not significantly more likely to test for HIV compared with participants in the standard HIV testing information control arm at 3 months (76% vs. 71%; P = 0.40) and 6 months (73% vs. 72%; P = 0.81), respectively. CONCLUSIONS: This study evaluated an innovative intervention to increase HIV testing by matching individuals to optimal HIV testing approaches. Participants in both arms increased past 3-month HIV testing, suggesting that providing information on options and/or raising risk awareness is sufficient to significantly increase HIV testing.

Acculturation as a Moderator of HIV Risk Behavior Correlates Among Latino Men Who Have Sex with Men.

Acculturation is associated with increased sexual risk behaviors among heterosexual Latinos, but its influence among Latino gay, bisexual, and other men who have sex with men (MSM) remains less clear. Elements of acculturation may create distinct lived experiences among sexual minority Latinos, moderating how beneficial and adverse influences contribute to their sexual risk behaviors. Latino MSM living in New York City (n = 412) were recruited using a modified time-space venue- and web-based sampling method. Negative binomial regression models estimated associations between indicators of acculturation (i.e., language use, nativity status, ethnic identification), sexual minority stressors (i.e., internalized homophobia, sexual orientation-based discrimination), peer condom use norms, and the number of serodiscordant condomless anal intercourse (SDCAI) encounters. Acculturation indicators were then tested as simultaneous moderators of the influence of each predictor variable on the outcome. The association between internalized homophobia and SDCAI was significant only among English language speakers (aIRR = 3.05 [2.13, 4.37]) and those born outside of the U.S. (foreign-born = 0, aIRR = 0.17 [0.08, 0.36]). Sexual orientation-based discrimination and SDCAI were also positively associated among both English-speaking (aIRR = 1.82 [1.22, 2.72]) and foreign-born men (aIRR = 0.34 [0.14, 0.84]). Stronger ethnic identification also moderated the protective effects of peer condom use norms on SDCAI (aIRR = 0.28 [0.15, 0.52]). Results suggest that different dimensions of acculturation help shape how both stressors and protective factors influence HIV risk among Latino MSM. Future research is needed to examine the mechanisms through which these differences in acculturation may act on sexual risk behaviors among Latino MSM.

Impact of a Community-level Intervention on HIV Stigma, Homophobia and HIV Testing in New York City: Results from Project CHHANGE.

Background: HIV stigma and homophobia are barriers to access to HIV prevention and treatment services. Project CHHANGE, Challenge HIV Stigma and Homophobia and Gain Empowerment, was a multicomponent intervention designed to reduce community-level HIV stigma and homophobia via workshops, space-based events and bus shelter ads delivered to community-based organizations and neighborhood residents in a high HIV prevalence, primarily African-American, Black and/or Afro-Caribbean, neighborhood in New York City (NYC). Methods: Serial cross-sectional, street intercept surveys among residents of the invention neighborhood and matched control neighborhood were conducted before and after the intervention. Propensity score matching and generalized estimating equation regression models assessed the impact of CHHANGE on HIV stigma and homophobia. HIV testing service utilization data were assessed and multivariable models of self-reported HIV testing among post-intervention street survey respondents were built. Results: We did not find a significant treatment effect on HIV stigma and homophobia among residents of the intervention neighborhood as compared with control community residents. However, HIV testing increased by 350% at the testing site in the intervention community after the intervention implementation. Further, lower HIV stigma, attending an HIV stigma workshop and having friends or family living with HIV were independently associated with past six-month HIV testing among post-intervention respondents in both neighborhoods. Conclusions: CHHANGE was feasible and acceptable to community residents. Evaluating community-level interventions is challenging. Our triangulated approach yielded somewhat conflicting results, which may be due to design limitations. Further research is needed to understand whether and how CHHANGE affected HIV testing.

Prevalence and mapping of hepatitis C infections among men who have sex with men in New York City.

Emerging sexually transmitted hepatitis C virus (HCV) epidemics among men who have sex with men (MSM) have been reported worldwide, with higher HCV infection rates among those who are HIV-infected. This study aims to determine prevalence of recent and chronic HCV infections among community-recruited MSM in New York City (NYC), map HCV infections by home, social, and sexual neighborhoods, and identify clusters of genetically linked HCV variants using phylogenetic analysis. The NYC M2M study recruited MSM via modified time-space, venue-based sampling and internet/mobile app-based recruitment during 2010-13. Participants completed a Google Earth map on neighborhoods of where they lived, socialized, and had sex in the last 3 months, an ACASI questionnaire, and a sexual network inventory about their sex partners. The men received HIV testing and provided serum samples. Testing on stored serum samples included HCV antibody and RNA viral load, HCV antibody avidity assay (avidity index <30% with positive viral load is considered recently infected), and HCV RNA extraction and amplification to generate a 432 base-pair region of Core/E1 for sequencing and phylogenetic analysis. Historic local controls were included in the phylogenetic analysis. Of 1,028 MSM, 79.7% were HIV-negative and 20.3% HIV-positive. Twenty nine MSM (2.8%) were HCV antibody-positive. MSM who were HCV antibody-positive reported a median of 2 male sex partners in last 3 months, with 6.9% aged 18-24, 17.2% 25-29, 13.8% 30-39, and 62.1% 40 and over. 8.1% of HIV-positive MSM were HCV antibody-positive vs. 1.5% of HIV-negative men (p<0.0001). Of 29 HCV-antibody positive MSM, 12 (41%) were HCV RNA-positive (11 subtype 1a and 1 subtype 1b). Two of 12 HCV RNA-positive participants had low antibody avidity values, suggesting recent HCV infection. HCV antibody seropositivity was significantly associated with older age >40 years, adjusted odds ratio (aOR) 3.56 (95% CI 1.57, 8.08), HIV-positive serostatus, aOR 3.18 (95% CI 1.40, 7.22), any sexually transmitted infection (STI) in the last 3 months, aOR 2.81 (95% CI 1.11, 7.13), and injection drug use (IDU) ever, aOR 4.34 (95% CI 1.69, 11.17). Mapping of HCV infections differed slightly by home, social, and sexual neighborhoods. Based on phylogenetic analysis from 12 HCV RNA-positive samples, no evidence of a clustered HCV epidemic was found. Overall HCV seroprevalence was 2.8% among community-recruited MSM in NYC, with higher prevalence among HIV-positive MSM compared to HIV-negative MSM. Only two participants were found to have recent HCV infection, with no evidence of a clustered HCV epidemic based on phylogenetic analysis. Our results support testing of HCV infection among HIV-negative MSM if they report having a recent STI and IDU in the past rather than universal HCV testing in all HIV-negative MSM.

Post-exposure Prophylaxis Awareness, Knowledge, Access and Use Among Three Populations in New York City, 2016-17.

Post-exposure prophylaxis (PEP) is a cost-effective, but underused HIV prevention strategy. PEP awareness, knowledge, access, and usage was assessed among young men of color who have sex with men (YMSMOC; n = 177), transgender women (TW; n = 182), and cisgender women of color (CWOC; n = 170) in New York City. 59% were aware of PEP: 80% among YMSMOC, 63% among TW and 34% among CWOC (p < 0.001). 13% had ever used PEP. PEP awareness was higher among YMSMOC with a recent HIV test and lower among those with ≥ 4 partners. PEP awareness was lower among TW who anticipated stigma and reported barriers to taking PEP, and higher among TW who exchanged sex for resources. Among CWOC, more barriers to taking PEP reduced the odds of PEP awareness. PEP education and outreach needs to be deliberate about population-specific campaigns, with a need to focus on reducing PEP stigma and other barriers which impede PEP access.

An Event-Level Analysis of Condomless Anal Intercourse with a HIV-Discordant or HIV Status-Unknown Partner Among Black Men Who Have Sex with Men from a Multi-site Study.

Despite the high HIV incidence and prevalence among black men who have sex with men (BMSM), little research has examined partner characteristics, partner seeking venue, sexual position, substance use, and sexual risk behavior at the sex event-level among BMSM. Using the baseline data from a multi-site study of 807 BMSM stratified by their HIV status, the goal of this study was to conduct a detailed event-level analysis of 1577 male anal sex events to assess the factors associated with condomless anal intercourse (CLAI) with a HIV-discordant or HIV status-unknown partner. We found CLAI with an HIV-discordant or unknown HIV status partner among HIV-negative BMSM was negatively associated with having sex with a main partner, and was positively associated with taking both receptive and insertive sexual positions during sex. As compared to a sex partner met at bar, night club or dance club, HIV-positive BMSM were less likely to engage in CLAI with HIV-discordant and unknown HIV status partner met at party or friend's house or at community organizations. HIV-positive BMSM had lower odds of engaging in CLAI with HIV-discordant and unknown HIV status partner if they had insertive sexual position or both receptive and insertive sexual positions. These results underscore the importance of delineating unique sex event-level factors associated with sexual risk behavior depending on individuals' HIV status. Our findings suggest event-level partner characteristics, sexual position, and partner seeking venues may contribute to disparities in HIV incidence.

Preferences for HIV test characteristics among young, Black Men Who Have Sex With Men (MSM) and transgender women: Implications for consistent HIV testing.

BACKGROUND: Promoting consistent HIV testing is critical among young, Black Men Who Have Sex With Men (MSM) and transgender women who are overrepresented among new HIV cases in the United States. New HIV test options are available, including mobile unit testing, one-minute testing, at home or self-testing and couples HIV testing and counseling (CHTC). In the context of these newer options, the objective of this study was to explore whether and how preferences for specific characteristics of the tests acted as barriers to and/or facilitators of testing in general and consistent testing specifically among young Black MSM and transgender women aged 16 to 29. METHODS: We conducted 30 qualitative, semi-structured, in-depth interviews with young, Black, gay, bisexual or MSM and transgender women in the New York City metropolitan area to identify preferences for specific HIV tests and aspects of HIV testing options. Participants were primarily recruited from online and mobile sites, followed by community-based, face-to-face recruitment strategies to specifically reach younger participants. Thematic coding was utilized to analyze the qualitative data based on a grounded theoretical approach. RESULTS: We identified how past experiences, perceived test characteristics (e.g., accuracy, cost, etc.) and beliefs about the "fit" between the individual, and the test relate to preferred testing methods and consistent testing. Three major themes emerged as important to preferences for HIV testing methods: the perceived accuracy of the test method, venue characteristics, and lack of knowledge or experience with the newer testing options, including self-testing and CHTC. CONCLUSIONS: These findings suggest that increasing awareness of and access to newer HIV testing options (e.g., free or reduced price on home or self-tests or CHTC available at all testing venues) is critical if these new options are to facilitate increased levels of consistent testing among young, Black MSM and transgender women. Addressing perceptions of test accuracy and supporting front line staff in creating welcoming and safe testing environments may be key intervention targets. Connecting young Black MSM and transgender women to the best test option, given preferences for specific characteristics, may support more and more consistent HIV testing.

Performance of the BioPlex 2200 HIV Ag-Ab assay for identifying acute HIV infection.

BACKGROUND: Assays that detect HIV antigen (Ag) and antibody (Ab) can be used to screen for HIV infection. OBJECTIVES: To compare the performance of the BioPlex 2200 HIV Ag-Ab assay and two other Ag/Ab combination assays for detection of acute HIV infection. STUDY DESIGN: Samples were obtained from 24 individuals (18 from the US, 6 from South Africa); these individuals were classified as having acute infection based on the following criteria: positive qualitative RNA assay; two negative rapid tests; negative discriminatory test. The samples were tested with the BioPlex assay, the ARCHITECT HIV Ag/Ab Combo test, the Bio-Rad GS HIV Combo Ag-Ab EIA test, and a viral load assay. RESULTS: Twelve (50.0%) of 24 samples had RNA detected only ( > 40 to 13,476 copies/mL). Ten (43.5%) samples had reactive results with all three Ag/Ab assays, one sample was reactive with the ARCHITECT and Bio-Rad assays, and one sample was reactive with the Bio-Rad and BioPlex assays. The 11 samples that were reactive with the BioPlex assay had viral loads from 83,010 to >750,000 copies/mL; 9/11 samples were classified as Ag positive/Ab negative by the BioPlex assay. CONCLUSIONS: Detection of acute HIV infection was similar for the BioPlex assay and two other Ag/Ab assays. All three tests were less sensitive than a qualitative RNA assay and only detected HIV Ag when the viral load was high. The BioPlex assay detected acute infection in about half of the cases, and identified most of those infections as Ag positive/Ab negative.
