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.

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.

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.

1970s and 'Patient 0' HIV-1 genomes illuminate early HIV/AIDS history in North America.

The emergence of HIV-1 group M subtype B in North American men who have sex with men was a key turning point in the HIV/AIDS pandemic. Phylogenetic studies have suggested cryptic subtype B circulation in the United States (US) throughout the 1970s and an even older presence in the Caribbean. However, these temporal and geographical inferences, based upon partial HIV-1 genomes that postdate the recognition of AIDS in 1981, remain contentious and the earliest movements of the virus within the US are unknown. We serologically screened >2,000 1970s serum samples and developed a highly sensitive approach for recovering viral RNA from degraded archival samples. Here, we report eight coding-complete genomes from US serum samples from 1978-1979-eight of the nine oldest HIV-1 group M genomes to date. This early, full-genome 'snapshot' reveals that the US HIV-1 epidemic exhibited extensive genetic diversity in the 1970s but also provides strong evidence for its emergence from a pre-existing Caribbean epidemic. Bayesian phylogenetic analyses estimate the jump to the US at around 1970 and place the ancestral US virus in New York City with 0.99 posterior probability support, strongly suggesting this was the crucial hub of early US HIV/AIDS diversification. Logistic growth coalescent models reveal epidemic doubling times of 0.86 and 1.12 years for the US and Caribbean, respectively, suggesting rapid early expansion in each location. Comparisons with more recent data reveal many of these insights to be unattainable without archival, full-genome sequences. We also recovered the HIV-1 genome from the individual known as 'Patient 0' (ref. 5) and found neither biological nor historical evidence that he was the primary case in the US or for subtype B as a whole. We discuss the genesis and persistence of this belief in the light of these evolutionary insights.

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.

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.

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.

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.

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.

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.

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.

Lessons for Patient Education Around Long-Acting Injectable PrEP: Findings from a Mixed-Method Study of Phase II Trial Participants.

This study aimed to identify patients' physical and psychosocial experiences of an investigational long-acting injectable PrEP product to aid in the development of patient and provider education materials. Twenty-eight participants of a Phase 2 safety, tolerability, and acceptability study of long-acting integrase inhibitor cabotegravir (CAB-LA) were interviewed on their physical and psychosocial experiences of the injections. Five themes emerged through a framework analysis on these interview transcripts: (1) injection-related pain is highly variable across individuals; (2) pain is more impactful after the injections than during; (3) patient anxiety is critical, but does not determine the experience of injections and decreases over time; (4) intimacy and awkwardness of gluteal injections impacts patients' experiences; (5) patient education and care strategies can mitigate the above factors. These findings can inform further sociobehavioral research within Phase 3 efficacy trials of CAB-LA, as well as patient education and provider guidance for future injectable PrEP products.

Higher T-Cell Responses Induced by DNA/rAd5 HIV-1 Preventive Vaccine Are Associated With Lower HIV-1 Infection Risk in an Efficacy Trial.

Background: It is important to identify vaccine-induced immune responses that predict the preventative efficacy of a human immunodeficiency virus (HIV)-1 vaccine. We assessed T-cell response markers as correlates of risk in the HIV Vaccine Trials Network (HVTN) 505 HIV-1 vaccine efficacy trial. Methods: 2504 participants were randomized to DNA/rAd5 vaccine or placebo, administered at weeks 0, 4, 8, and 24. Peripheral blood mononuclear cells were obtained at week 26 from all 25 primary endpoint vaccine cases and 125 matched vaccine controls, and stimulated with vaccine-insert-matched peptides. Primary variables were total HIV-1-specific CD4+ T-cell magnitude and Env-specific CD4+ polyfunctionality. Four secondary variables were also assessed. Immune responses were evaluated as predictors of HIV-1 infection among vaccinees using Cox proportional hazards models. Machine learning analyses identified immune response combinations best predicting HIV-1 infection. Results: We observed an unexpectedly strong inverse correlation between Env-specific CD8+ immune response magnitude and HIV-1 infection risk (hazard ratio [HR] = 0.18 per SD increment; P = .04) and between Env-specific CD8+ polyfunctionality and infection risk (HR = 0.34 per SD increment; P < .01). Conclusions: Further research is needed to determine if these immune responses are predictors of vaccine efficacy or markers of natural resistance to HIV-1 infection.

Sexual Networks, Dyadic Characteristics, and HIV Acquisition and Transmission Behaviors Among Black Men Who Have Sex With Men in 6 US Cities.

The role of sexual networks in the epidemiology of human immunodeficiency virus (HIV) among black men who have sex with men (MSM) is poorly understood. Using data from 1,306 black MSM in the BROTHERS Study (2009-2010) in the United States, we examined the relationships between multiple sexual dyadic characteristics and serodiscordant/serostatus-unknown condomless sex (SDCS). HIV-infected participants had higher odds of SDCS when having sex at least weekly (odds ratio (OR) = 2.41, 95% confidence interval (CI): 1.37, 4.23) or monthly (OR = 1.94, 95% CI: 1.17, 3.24) versus once to a few times a year. HIV-uninfected participants had higher odds of SDCS with partners met offline at sex-focused venues (OR = 1.79, 95% CI: 1.15, 2.78) versus partners met online. In addition, having sex upon first meeting was associated with higher odds of SDCS (OR = 1.49, 95% CI: 1.21, 1.83) than was not having sex on first meeting, while living/continued communication with sexual partner(s) was associated with lower odds of SDCS (weekly: OR = 0.64, 95% CI: 0.47, 0.85; monthly: OR = 0.60, 95% CI: 0.44, 0.81; yearly: OR = 0.58, 95% CI: 0.39, 0.85) versus discontinued communication. Persons with primary/steady nonprimary partners versus commercial partners had lower odds of SDCS regardless of HIV serostatus. This suggests the need for culturally relevant HIV prevention efforts for black MSM that facilitate communication with sexual partners especially about risk reduction strategies, including preexposure prophylaxis.

Population-Level Immune-Mediated Adaptation in HIV-1 Polymerase during the North American Epidemic.

UNLABELLED: Human leukocyte antigen (HLA) class I-associated polymorphisms in HIV-1 that persist upon transmission to HLA-mismatched hosts may spread in the population as the epidemic progresses. Transmission of HIV-1 sequences containing such adaptations may undermine cellular immune responses to the incoming virus in future hosts. Building upon previous work, we investigated the extent of HLA-associated polymorphism accumulation in HIV-1 polymerase (Pol) through comparative analysis of linked HIV-1/HLA class I genotypes sampled during historic (1979 to 1989; n = 338) and modern (2001 to 2011; n = 278) eras from across North America (Vancouver, BC, Canada; Boston, MA; New York, NY; and San Francisco, CA). Phylogenies inferred from historic and modern HIV-1 Pol sequences were star-like in shape, with an inferred most recent common ancestor (epidemic founder virus) sequence nearly identical to the modern North American subtype B consensus sequence. Nevertheless, modern HIV-1 Pol sequences exhibited roughly 2-fold-higher patristic (tip-to-tip) genetic distances than historic sequences, with HLA pressures likely driving ongoing diversification. Moreover, the frequencies of published HLA-associated polymorphisms in individuals lacking the selecting HLA class I allele was on average ∼2.5-fold higher in the modern than in the historic era, supporting their spread in circulation, though some remained stable in frequency during this time. Notably, polymorphisms restricted by protective HLA alleles appear to be spreading to a greater relative extent than others, though these increases are generally of modest absolute magnitude. However, despite evidence of polymorphism spread, North American hosts generally remain at relatively low risk of acquiring an HIV-1 polymerase sequence substantially preadapted to their HLA profiles, even in the present era. IMPORTANCE: HLA class I-restricted cytotoxic T-lymphocyte (CTL) escape mutations in HIV-1 that persist upon transmission may accumulate in circulation over time, potentially undermining host antiviral immunity to the transmitted viral strain. We studied >600 experimentally collected HIV-1 polymerase sequences linked to host HLA information dating back to 1979, along with phylogenetically reconstructed HIV-1 sequences dating back to the virus' introduction into North America. Overall, our results support the gradual spread of many-though not all-HIV-1 polymerase immune escape mutations in circulation over time. This is consistent with recent observations from other global regions, though the extent of polymorphism accumulation in North America appears to be lower than in populations with high seroprevalence, older epidemics, and/or limited HLA diversity. Importantly, the risk of acquiring an HIV-1 polymerase sequence at transmission that is substantially preadapted to one's HLA profile remains relatively low in North America, even in the present era.

Knowledge, Stereotyped Beliefs and Attitudes Around HIV Chemoprophylaxis in Two High HIV Prevalence Neighborhoods in New York City.

HIV chemoprophylaxis (PrEP/PEP) has emerged as a transformative prevention tool to reduce infection rates and decrease disease burden. However, uptake is low, and efficacy depends upon adherence. To maximize impact, potential barriers to uptake and adherence must be identified and understood. Using univariate and logistic regression analytic methods, we assessed associations among potential barriers to uptake and adherence, including HIV chemoprophylaxis knowledge, negative stereotyped beliefs about people who use it and negative attitudes towards HIV chemoprophylaxis use by relatives among 583 residents of two high HIV prevalence neighborhoods in New York City. About a quarter of respondents knew about HIV chemoprophylaxis and over 50 % endorsed negative stereotyped beliefs about users; yet, approximately two-thirds had positive attitudes toward its use among a male or female relative. Young age, having lesbian or gay friends/family members and low levels of homophobia were associated with not endorsing negative stereotyped beliefs. Negative stereotyped beliefs were not associated with negative attitudes toward HIV chemoprophylaxis use among relatives. Implications for PrEP dissemination are discussed.

Associations Among Neighborhood Characteristics and Sexual Risk Behavior Among Black and White MSM Living in a Major Urban Area.

Identifying neighborhood characteristics associated with sexual HIV risk behavior among gay, bisexual and other men who have sex with men (MSM) living in urban areas may inform the development of policies and programs to reduce risk and subsequently HIV prevalence in urban areas. New York City M2M was a cross-sectional study designed to identify neighborhood-level characteristics associated with sexual risk behaviors among MSM living in New York City. This paper presents results of an analysis of neighborhood-level indicators of three distinct social theories of influence of the neighborhood environment on human behavior: physical disorder, social disorganization and social norms theories. Using multilevel modeling on a sample of 766 MSM stratified by race/ethnicity, we found little support for the role of social disorganization on the sexual risk behavior of MSM, whereas different indicators of physical disorder exerted negative effects across race groups. Our results suggest that the beneficial effects of housing stock maintenance and general neighborhood physical orderliness and cleanliness may have positive effects beyond those traditionally studied for African American MSM and that the field needs novel theorizing regarding whether and how neighborhood or virtual community-level factors relate to sexual behavior among MSM.

Social Network Factors as Correlates and Predictors of High Depressive Symptoms Among Black Men Who Have Sex with Men in HPTN 061.

Depression is linked to a range of poor HIV-related health outcomes. Minorities and men who have sex with men (MSM), suffer from high rates of depression. The current study examined the relationship between depressive symptoms and social network characteristics among community-recruited Black MSM in HPTN 061 from 6 US cities. A social network inventory was administer at baseline and depression was assessed with the CES-D at baseline, 6, and 12-months. At baseline, which included 1167 HIV negative and 348 HIV positive participants, size of emotional, financial, and medical support networks were significantly associated with fewer depressive symptoms. In longitudinal mixed models, size of emotional, financial, and medical support networks were significantly associated with fewer depressive symptoms as was the number of network members seen weekly. In the multivariate analyses, size of medical appointment network remained statistically significant (aOR 0.89, CI 0.81-0.98). These findings highlight the importance of network support of medical care on depression and suggest the value of support mobilization.

Congruence of Home, Social and Sex Neighborhoods among Men Who Have Sex with Men, NYCM2M Study.

Substantial literature demonstrates the influence of the neighborhood environment on health behaviors and outcomes. But limited research examines on how gay and bisexual men experience and exist in various geographic and virtual spaces and how this relates to their sexual behavior. New York City Men 2 Men (NYCM2M) was a cross-sectional study designed to identify neighborhood-level characteristics within the urban environment that influence sexual risk behaviors, substance use, and depression among men who have sex with men (MSM) living in NYC. The sample was recruited using a modified venue-based time-space sampling methodology and through select websites and mobile applications. Whether key neighborhoods of human activity, where a participant resided (termed home), socialized (termed social), or had sex most often (termed sex), were the same or different was evaluated. "Congruence" (or the sameness) of home, social, and most often sex neighborhood was reported by 17 % of men, while 30 % reported that none of their neighborhoods were the same. The largest group of men (39 %) reported that their home and sex neighborhoods were the same but their social neighborhood was different while 10 % reported that their home neighborhood was different than their social and sex neighborhood; 5 % men reported same home and social neighborhoods with a different sex neighborhood. Complete neighborhood incongruence was highest among men who were Black and/or Latino, had lower education and personal income levels, and had greater financial insecurity. In adjusted analysis, serodiscordant condomless anal intercourse and condomless anal intercourse with partners from the Internet or mobile applications were significantly associated with having the same social and sex (but not home) neighborhoods. Understanding the complexity of how different spaces and places relate to the health and sexual behavior of MSM is essential for focusing interventions to best reach various populations of interest.
