Explaining disparities in HIV infection among black and white men who have sex with men: a meta-analysis of HIV risk behaviors

PrEP Use and Sexually Transmitted Infections Are Not Associated Longitudinally in a Cohort Study of Young Men Who Have Sex with Men and Transgender Women in Chicago

Our goal was to understand whether PrEP users are at increased risk for STIs, a key target in prevention efforts aimed at disrupting the spread of STIs and likely downstream HIV infection risk. Data were collected as part of RADAR, a cohort study of young men who have sex with men and transgender women (YMSM/TW) (aged 16-29) in Chicago. Longitudinal lagged regression models were utilized to assess the relationship between PrEP use and odds of rectal STI acquisition. Mediation models were also utilized to consider the potential pathway between PrEP use, condomless anal sex (CAS), and rectal STI. One hundred eighty-seven (16.2%) participants had a rectal STI at baseline. In both cross-sectional and longitudinal models, no significant association was observed between PrEP use and STI. In mediation models, PrEP use was significantly associated with increased CAS, however, CAS was not associated with STI status. We demonstrated that, overall, PrEP use was not associated with STIs among YMSM/TW but did observe that PrEP users were more likely to report increased participation in CAS at the subsequent study visit.

Does internalized racism matter in HIV risk? Correlates of biomedical HIV prevention interventions among Black men who have sex with men in the United States

Black men who have sex with men (MSM) account for 26% of all new HIV infections in the United States. Biomedical HIV interventions have proven to reduce HIV infections however the use of these interventions by Black MSM is inconsistent. Research suggests that internalized racism may contribute to inconsistent biomedical HIV interventions (condom use and PrEP use) among Black MSM. Using a national sample of 432 Black MSM, we examined the relationship between condom and PrEP use and internalized racism. The results suggest there is some evidence for an association between internalized racism and PrEP use. In addition, internalized racism was not associated with condom use for both insertive and receptive anal sex among Black MSM. These finding suggest the relationship between internalized racism and HIV prevention strategies is not facile and more attention is needed to understand the true impact of racism, both internal and societal, on HIV prevention strategies among Black MSM. These findings underscore the nature of racism in the daily lives of Black MSM and how it impacts HIV prevention strategies adopted by these men.

The dual contingencies of ethnoraciality: Status-context disparities in health information sources among sexual minorities

Researchers often explore health (care) beliefs as a function of individual characteristics; yet, few consider the role of context in shaping both beliefs and the behaviors that are informed by them. As a sociopolitical construct, ethnoraciality provides a concerning source of bias in studies of health (care) beliefs because it inhabits both individual and contextual forms. This study examines whether the ethnoracial context of the residential area where sexual minorities live is associated with a particular health (care) belief - sources of trustworthy health information - and considers how ethnoracial group membership status differentiates these ecological associations drawing on mediation and moderation models. Using data from the 2010 Social Justice Sexuality Project, our analysis shows that sexual minorities who live with high concentrations of Latinos and Whites are less likely to rely exclusively on medical professionals for trustworthy health information than those who live with high concentrations of Blacks. Moreover, exclusive reliance on medical professionals for health information among Black and Latino sexual minorities is stronger in co-ethnic communities (predominately Black and Latino areas, respectively). The analysis also documents status and contextual differentials and status-context contingencies of reliance on the Internet, social networks, and multiple agents ("triangulation") as sources of health information. Findings suggest that place-based co-ethnic networks may facilitate disease prevention among Black and Latino sexual minorities by improving the quality of their relationships with sick role gatekeepers and breaking down the silos of the medical complex. The study concludes by considering the value of a place-based approach to alleviating health disparities among sexual minorities vis-à-vis the health care system.

Collective Avoidance of Social and Health Venues and HIV Racial Inequities: Network Modeling of Venue Avoidance on Venue Affiliation, Social Networks, and HIV Risk

Many younger Black men who have sex with men (YBMSM) are exposed to homonegativity, societal stigma, and racial discrimination in their social environment. This study uses a social network modeling methodology to identify aspects of the social environment that are not often described, that is, the places and spaces or "venues" where YBMSM socialize or where they receive HIV prevention services. In particular, we identify the structural features of avoidance of these venues as an indicator of negative experiences, using bipartite exponential random graph models. Our study theorizes that YBMSM avoid certain venues en masse through information diffusion among social network members. We specify two social mechanisms of collective venue avoidance-(1) homophily (i.e., ego-alter similarity in venue avoidance) and (2) popular opinion leaders (as early adopters)-and test the corresponding hypotheses that (Hypothesis 1) socially connected individuals avoid venues together and that (Hypothesis 2) popular individuals would be more likely to avoid venues. Based on data collected from YBMSM aged 16 to 29 years between 2014 and 2016 in Houston, Texas (N = 227) and Chicago, Illinois (N = 241), results indicate that Hypothesis 1 was supported in both cities but that Hypothesis 2 was supported only in Chicago. The findings suggest that the structural patterns of venue avoidance are different between cities and may inform dissemination of prevention messages and delivery of venue- and social influence-based HIV interventions.

Developing targeted HIV risk predictors for young black men who have sex with men: a two-city comparative study

HIV burden in the United States is geographically and demographically heterogeneous. While efforts over the last few decades have reduced HIV incidence, young black men who have sex with men (YBMSM) account for a significant portion of new HIV diagnoses compared to any other race and age group. The Centers for Disease Control and Prevention has allocated funding to help reduce HIV in the YBMSM community; however, their recommended screening/treatment criteria do not emphasize demographic specificity. To better guide more applicable screening guidelines specifically for YBMSM, we examine demographic, behavioral, sexual network, and biological predictors of HIV status among YBMSM in two demographically distinct cities with high HIV burden in the United States: Chicago, IL and Los Angeles, CA. We perform multivariable logistic regressions to identify predictors of HIV in these populations. We found that having a history of syphilis was the only statistically significant predictor across both cities despite inclusion of other characteristics previously shown to be associated with HIV among YBMSM. Syphilis history could be a powerful HIV risk indicator for YBMSM and, therefore, should be integrated into clinical screening practices for critical biomedical prevention options like HIV pre-exposure prophylaxis.

What's PrEP?: peer navigator acceptability among minority MSM in Washington

BACKGROUND

Peer navigation is a promising strategy to link at-risk minority men who have sex with men (MSM) to HIV prevention services including pre-exposure prophylaxis (PrEP).

METHODS

Thirty-two Black and 63 Latinx HIV-negative MSM living in western Washington completed a survey examining attitudes towards peer navigation and PrEP. Factor analysis derived a score for peer navigator acceptability, and linear regression identified associations with this outcome.

RESULTS

Forty-eight percent were interested in peer navigation. Being insured, higher sexual stigma, and higher PHQ-9 score were associated with higher acceptability, while higher income and having a regular medical provider were associated with lower acceptability. In multivariable analysis, higher sexual stigma predicted higher acceptability, while higher income predicted lower acceptability. Men preferred that peers be matched on sexual orientation, race, age and culture.

CONCLUSION

Peer navigation interventions to reach minority men should address stigma, focus on lower-income men, and try to match peers to clients to the extent possible.

HIV Prevention Research on Men Who Have Sex With Men: A Scoping Review of Systematic Reviews, 1988-2017

In the United States, men who have sex with men (MSM) are disproportionately affected by HIV. To identify research gaps and inform HIV prevention for MSM, we conducted a scoping review of systematic reviews using CDC's Prevention Research Synthesis database. Eligibility criteria comprised English-language systematic reviews focused on HIV prevention for MSM, published during 1988-2017, and included at least one U.S. primary study. We coded data type, subpopulations, topics, and key findings. To assess study quality, we used the Assessment of Multiple Systematic Reviews (AMSTAR). Among 129 relevant systematic reviews, study quality was high or moderate for 63%. Most common topics were sexual behavior and disease vulnerability. The most frequently mentioned MSM subgroups were HIV-positive, Black or African American, and young. Research gaps include Hispanic/Latino MSM, pre-exposure prophylaxis (PrEP), treatment as prevention, social determinants of health, health disparities, syndemics, and protective factors for sexual health.

Examining the Impact of a Psychosocial Syndemic on Past Six-Month HIV Screening Behavior of Black Men who have Sex with Men in the United States: Results from the POWER Study

Syndemic production theory has been used to explore HIV transmission risk or infections but has not been used to investigate prevention behavior, or with large samples of non-Whites. This analysis is the first to explore the impact of syndemic factors on previous six-month HIV screening behavior among US Black MSM. Data from Promoting Our Worth, Equality and Resilience (POWER) were analyzed from 3294 participants using syndemic variable counts and measures of interaction/synergy. Syndemic variables included: past three-month poly-drug use, depression, last year intimate partner violence, HIV risk and problematic binge drinking. BMSM reporting two syndemic factors were more likely to report screening (AOR = 1.37, 95% CI 1.04-1.80; p = 0.028) with no significant associations for three or more conditions. Measures of joint effect revealed that there were synergies among depression, problematic binge drinking and poly-drug use but these psychosocial factors cannot entirely explain testing patterns and excess disease burden among BMSM.

Leveraging Community Engagement: The Role of Community-Based Organizations in Reducing New HIV Infections Among Black Men Who Have Sex with Men

There is growing recognition that a singular focus on biomedical treatments is insufficient to address the HIV prevention and health-care needs of Black men who have sex with men (Black MSM). Ending the HIV epidemic requires a multifactorial approach accounting for the social, cultural, economic, and environmental factors that drive transmission of HIV and other STDs. The two case studies presented were implemented by community-based organizations that have extensive experience with the target population and previous experience implementing HIV prevention-related programs and projects in the Jackson, Mississippi, metropolitan area. Culturally appropriate HIV prevention interventions that explicitly acknowledge the social determinants of health, particularly stigma and discrimination, both racial and sexual, are critical to reducing the number of new infections. These culturally appropriate and locally derived HIV prevention interventions provide a model for HIV health-care providers, public health officials, and community leaders to address the unique needs of Black MSM.

Social Networks Moderate the Syndemic Effect of Psychosocial and Structural Factors on HIV Risk Among Young Black Transgender Women and Men who have Sex with Men

The interaction between the cumulative effect of psychosocial and structural factors (i.e. syndemic effect) and social networks among young Black transgender women and men who have sex with men (YBTM) remains understudied. A representative cohort of 16-29 year-old YBTM (n = 618) was assessed for syndemic factors [i.e. substance use; community violence; depression; poverty; justice system involvement (JSI)], social network characteristics, condomless anal sex (CAS), group sex (GS), and HIV-infection. The syndemic index significantly increased the odds of CAS, GS, and HIV-infection, and these effects were moderated by network characteristics. Network JSI buffered the effect on CAS, romantic network members buffered the effect on GS, and network age and proportion of family network members buffered the effect on HIV-infection. The proportion of friend network members augmented the effect on GS and HIV-infection. Future research to prevent HIV among YBTM should consider social network approaches that target both structural and psychosocial syndemic factors.

No Evidence of Bias in Sexual Partnership Corroboration by Race and Ethnicity Among a Diverse Cohort of Young Men Who Have Sex with Men and Transgender Women

Black men who have sex with men (MSM) continue to experience disproportionately high HIV incidence rates relative to their white peers. Yet, Black MSM do not report higher levels of sexual risk behavior, and contextual factors such as access to care and sexual networks only partially explain these disparities. However, risk misclassification could help explain this paradox, if measurement biases systematically underestimate sexual risk behavior among Black MSM relative to their peers. The current study examined variation in sexual partnership corroboration in the RADAR study, a large and diverse cohort of young MSM and transgender women. Network data were elicited regarding all sexual partners in the prior 6 months, including instances where participants reported other participants as sexual partners. Using these data, anal and condomless anal sex partners were separately examined using a series of exponential random graph models to estimate the rate of corroboration of sexual connections between participants and examine whether this parameter varied by race/ethnicity. For both types of behavior, providing separate estimates for corroboration across race/ethnicity groups reduced model fit and did not significantly vary across groups. Accordingly, we found no evidence of measurement bias by race/ethnicity in the current data. However, overall rates of corroboration (41.2-50.3%) were low, suggesting substantial levels of measurement error. Accordingly, it is vital that researchers continue to improve upon methods to measure risk behavior in order to maximize their validity. We discuss the implications of these findings, including potential alternative causes of risk misclassification (e.g., sampling bias) and future directions to reduce measurement error.

There's an App for That: Using Geosocial Networking Apps to Access Young Black Gay, Bisexual, and other MSM at Risk for HIV

PURPOSE

Young black gay, bisexual, and other MSM (YBMSM) that carry a disproportionate HIV burden in the US Geosocial networking applications (GSN apps) are environments that may increase HIV risk among users. This study explored the acceptability and feasibility of using these apps for HIV/sexually transmitted infection (STI) public health outreach.

DESIGN

Semi-structured in-depth qualitative interviews.

SETTING

A frequently reported GSN app for meeting sex partners by newly diagnosed HIV-infected MSM in Baltimore.

PARTICIPANTS

Seventeen YBMSM aged 18 to 24 (mean = 21.5/SD = 1.8) who were logged-on to the GSN app in venues or census tracts in high HIV transmission areas.

METHODS

Participants completed 60 to 90 minute semi-structured interviews, which were audio-recorded and transcribed. Interview data were analyzed in NVivo10 using categorical analysis and double-coded until consistency was achieved.

RESULTS

Participants described GSN apps as acceptable and feasible resources for public health practitioners seeking to access YBMSM to provide HIV/STI treatment and prevention services and resources. Three themes emerged: (1) the need to authenticate public health messages to distinguish from spam; (2) improved access to YBMSM including opportunities to identify and access virtual congregations of youth in non-gay-related spaces; and (3) the importance of avoiding stigmatizing YBMSM when targeting sexual health messages.

CONCLUSION

GSN apps have great potential as tools for identifying and engaging at-risk YBMSM. Additional work is needed to understand limitations of this medium, to develop strategies to engage YBMSM without further stigmatizing them, and to maximize their outreach potential.

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.

Associations Between Neighborhood Problems and Sexual Behaviors Among Black Men Who Have Sex with Men in the Deep South: The MARI Study

There is a disproportionately high HIV incidence among Black men who have sex with men (MSM) despite equal or lower levels of HIV risk behaviors compared to White MSM. Due to high levels of racial segregation in the U.S., Black MSM have an elevated likelihood of living in neighborhoods that contain psychosocial stressors, which, in turn, may increase behaviors promoting HIV infection. We examined associations between perceived neighborhood problems and sexual behaviors among Black MSM in the Deep South, a population at highest risk of HIV. Data came from the MARI Study, which included Black MSM ages 18-66 years recruited from the Jackson, MS, and Atlanta, GA, metropolitan areas (n = 377). Participants completed questions about neighborhood problems (e.g., excessive noise, heavy traffic/speeding cars and trash/litter) and sexual behaviors (e.g., condomless sex and drug use before or during sex). We used Poisson's regression model with robust standard errors to estimate the adjusted prevalence ratio (aPR; 95% confidence intervals [CI]) of neighborhood problems (coded as tertiles [tertile 1 = low neighborhood problems, tertile 2 = medium neighborhood problems, tertile 3 = high neighborhood problems] as well as continuously) with sexual behaviors, after adjustment for sociodemographic characteristics and other variables. About one-fourth of the sample reported at least one neighborhood problem, with the most common (31.6%) being no/poorly maintained sidewalks, which indicates an infrastructural problem. In multivariable models, compared to those in the lowest tertile, those reporting more neighborhood problems (tertile 2: aPR = 1.49, 95% CI = 1.04, 2.14 and tertile 3: aPR = 1.53, 95% CI = 1.05, 2.24) reported more drug use before or during sex (p for trend = .027). Neighborhood problems may promote behaviors (e.g., drug use before or during sex) conducive to HIV infection. Structural interventions could improve community infrastructure to reduce neighborhood problems (e.g., no/poorly maintained sidewalks and litter). These interventions may help to reduce HIV incidence among Black MSM in the Deep South.

Father support is protective against the negative effects of perceived discrimination on CRP among sexual minorities but not heterosexuals

BACKGROUND

Exposure to sexual orientation-related discrimination among sexual minorities may lead to elevated levels of C-reactive protein (CRP) as compared to their heterosexual counterparts. However, little is known about factors that may buffer the association between discrimination and CRP among sexual minorities versus heterosexuals. The current study examined if the association between discrimination, sexual orientation, and CRP differed across levels of social support from one's father/father-figure or mother/mother-figure between sexual minorities and heterosexuals.

METHODS

Data came from Wave IV of the National Longitudinal Study of Adolescent to Adult Health (Add Health). The sample sizes for father support and mother support was 3167 and 3575, respectively. Participants ranged in age from 24 to 33 years. Stratified linear regression models examined if father and mother support moderated the association between discrimination and CRP among sexual minorities and heterosexuals.

RESULTS

Father support significantly moderated the association between discrimination and CRP among sexual minorities but not heterosexuals. Sexual minorities with higher father support and who experienced discrimination had lower CRP as compared to those with lower father support and who experienced discrimination. Mother support did not moderate the association between discrimination and CRP among either sexual minorities or heterosexuals.

CONCLUSION

Father support may mitigate the negative effects of stress from discrimination on CRP among sexual minorities. Future research should further examine the potential differential role that father support may play in reducing cardiovascular risk among sexual minorities versus heterosexuals who experience discrimination.

A Simple Symptom Score for Acute Human Immunodeficiency Virus Infection in a San Diego Community-Based Screening Program

Background

Treatment of acute human immunodeficiency virus (HIV) infection (AHI) decreases transmission and preserves immune function, but AHI diagnosis remains resource intensive. Risk-based scores predictive for AHI have been described for high-risk groups; however, symptom-based scores could be more generalizable across populations.

Methods

Adults who tested either positive for AHI (antibody-negative, HIV nucleic acid test [NAT] positive) or HIV NAT negative with the community-based San Diego Early Test HIV screening program were retrospectively randomized 2:1 into a derivation and validation set. In the former, symptoms significant for AHI in a multivariate logistic regression model were assigned a score value (the odds ratio [OR] rounded to the nearest integer). The score was assessed in the validation set using receiver operating characteristics and areas under the curve (AUC). An optimal cutoff score was found using the Youden index.

Results

Of 998 participants (including 261 non-men who have sex with men [MSM]), 113 had AHI (including 4 non-MSM). Compared to HIV-negative cases, AHI cases reported more symptoms (median, 4 vs 0; P < .01). Fever, myalgia, and weight loss were significantly associated with AHI in the multivariate model and corresponded to 11, 8, and 4 score points, respectively. The summed score yielded an AUC of 0.85 (95% confidence interval [CI], .77-.93). A score of ≥11 was 72% sensitive and 96% specific (diagnostic OR, 70.27).

Conclusions

A 3-symptom score accurately predicted AHI in a community-based screening program and may inform allocation of resources in settings that do not routinely screen for AHI.

Comparison of Two Distinct House Ball Communities Involved in an HIV Prevention Study: Baseline Data from the POSSE Project

For many Black/African American gay, bisexual, and other young men who have sex with men (B-GBMSM), the House/Ball Community (HBC) offers a social network where they can be free to express diverse sexual and gender identities, but HIV prevalence and stigma are high. The POSSE project is an effectiveness-implementation trial of a popular opinion leader intervention designed to address HIV prevention in the Chicago and Philadelphia HBCs. In June 2016 baseline behavioral data were collected along with HIV, gonorrhea and Chlamydia testing. Eligible participants were sexually-active YMSM or transgender women (TGW), between the ages of 15-24, who self-identified as Black. One-third participants (32.5%) met or exceeded the clinical cut-off for depressive symptoms. Approximately 18% of the participants across both cities reported that they were HIV-positive. Overall, the baseline data establishes the need for HIV and STI prevention interventions across both cities, as well as interventions to address other co-occurring epidemics.

A Person-Centered Approach to HIV-Related Protective and Risk Factors for Young Black Men Who Have Sex with Men: Implications for Pre-exposure Prophylaxis and HIV Treatment as Prevention

Although young Black men who have sex with men (YBMSM) are disproportionately affected by HIV, they may be more heterogeneous as a group than is typically appreciated. Thus, the present study used a person-centered data-analytic approach to determine profiles of HIV-related risk among YBMSM and whether these profiles could be distinguished by age, HIV status, and socioeconomic risk (i.e., socioeconomic distress). YBMSM (N = 1808) aged 18 to 29 years completed a survey of sociodemographic characteristics, HIV status, and HIV-related behavioral and attitudinal factors (i.e., safer-sex self-efficacy, negative condom attitudes, being in difficult sexual situations, being in difficult sexual relationships, HIV treatment optimism, perceived HIV stigma). Latent profile analysis was used to identify HIV risk profiles and whether age, HIV status, and socioeconomic distress were associated with these profiles. Four profiles emerged: low-, medium-, and high-risk profiles, respectively, and a mixed profile characterized by a tendency to be in difficult sexual situations and relationships while also reporting high safer-sex self-efficacy and low negative attitudes toward condom use. Difficult sexual situations emerged as the key defining indicator of whether a profile reflected higher or lower risk. Younger age, being HIV-positive, and socioeconomic distress were associated with having a higher-risk profile. Given that unique risk profiles emerged that were differentially predicted by sociodemographic characteristics and HIV status, these findings have implications for tailoring interventions to the needs of different subgroups of YBMSM. Also, disempowering or risky sexual situations and relationships among YBMSM must be addressed.

Reducing the African American HIV Disease Burden in the Deep South: Addressing the Role of Faith and Spirituality

Nearly half of HIV infections in the United States are concentrated among African Americans, and over half of new HIV infections occur in the South. African Americans have poorer outcomes in the entire continua of HIV and PrEP care. Complex social, structural, and behavioral factors contribute to our nation's alarming racial disparities in HIV infection, particularly in the Deep South. Despite the importance of faith, spirituality and religious practice in the lives of many African Americans, there has been little scientific investment exploring how African Americans' religious participation, faith and spirituality may impact our nation's HIV epidemic. This article summarizes the state of the science on this critical issue. We also identify opportunities for new scholarship on how faith, spirituality and religious participation may impact HIV care continuum outcomes in the South and call for greater federal research investment on these issues.

Improving the HIV Prevention Landscape to Reduce Disparities for Black MSM in the South

Black men who have sex with men (MSM) in the South have the highest rates of HIV diagnosis in the country adding to the persistent racial disparities in HIV experienced by this population. The current HIV prevention and care landscape is heavily driven by individual-level clinical and biomedical approaches that have shown progress in reducing HIV diagnoses, but yield less than adequate results in reducing the HIV racial disparities for Black MSM in the South. In efforts to enhance focus on reducing the racial HIV disparities and more completely address the needs of Black MSM in the South, we offer insight on comprehensive approaches that can complement our current HIV prevention and care portfolio. There are five domains we discuss which include: (1) leveraging and integrating resources; (2) building upon existing program models designed to reduce disparities; (3) workforce development and cultural sensitivity; (4) social determinants of health data utilization; and 5) policy considerations. We urge public health practitioners and healthcare providers to consider and incorporate the outlined approaches to improve HIV outcomes along the continuum of care and ultimately reduce disparities in HIV affecting the quality of life of Black MSM living in the South.

HIV, Sexually Transmitted Infection, and Substance Use Continuum of Care Interventions Among Criminal Justice-Involved Black Men Who Have Sex With Men: A Systematic Review

BACKGROUND

Because Black men who have sex with men (BMSM) experience high rates of both HIV and incarceration relative to other groups, the various stages of criminal justice involvement may serve as important intervention points for addressing HIV and related conditions in this group. Although systematic reviews of HIV interventions targeting MSM in general and BMSM in particular exist, no review has explored the range and impact of HIV, sexually transmitted infection (STI), and substance use prevention and care continuum interventions focused on criminal justice-involved (CJI) populations.

OBJECTIVES

To describe the range and impact of published HIV, STI, and related substance use interventions for US-based CJI populations and to understand their relevance for BMSM.

SEARCH METHODS

We conducted systematic searches in the following databases: PubMed, MEDLINE, Cochrane, CINAHL, and PsycINFO, covering the period preceding December 1, 2016.

SELECTION CRITERIA

We selected articles in scientific publications involving quantitative findings for studies of US-based interventions that focused on CJI individuals, with outcomes related to sexual or substance use risk behaviors, HIV, or STIs. We excluded studies if they provided no demographic information, had minimal representation of the population of interest (< 30 African American or Black male or transgender participants), had study populations limited to those aged younger than 18 years, or were limited to evaluations of preexisting programs.

DATA COLLECTION AND ANALYSIS

We abstracted data from these articles on study design; years covered; study location; participant number, demographics, and sexual orientation (if available); criminal justice setting or type; health condition; targeted outcomes; and key findings. We scored studies by using the Downs and Black quality and bias assessment. We conducted linear regression to examine changes in study quality by publication year.

MAIN RESULTS

Fifty-eight articles met inclusion criteria, including 8 (13.8%) modeling or cost-effectiveness studies and 13 (22.4%) randomized controlled trials. Just 3 studies (5.2%) focused on sexual or gender minorities, with only 1 focused on BMSM. In most studies (n = 36; 62.1%), however, more than 50% of participants were Black. The most common intervention addressed screening, including 20 empirical studies and 7 modeling studies. Education-focused interventions were also common (n = 15) and usually employed didactic rather than skill-building approaches. They were more likely to demonstrate increases in HIV testing, knowledge, and condom-use intentions than reductions in sex- and drug-risk behaviors. Screening programs consistently indicated cost-effectiveness, including with BMSM. Care continuum interventions for people living with HIV showed mixed results; just 3 involved randomized controlled trials, and these interventions did not show significant differences compared with control conditions. A minority of programs targeted non-custody-based CJI populations, despite their constituting a majority of the CJI population at any given time.

AUTHORS' CONCLUSIONS

Screening CJI populations for HIV and other STIs is effective and cost-efficient and holds promise for reducing HIV in BMSM. Education-based and care provision interventions also hold promise for addressing HIV, STIs, mental health, and substance use in CJI populations. Additional empirical and modeling studies and results specific to sexual minorities are needed; their paucity represents a disparity in how HIV is addressed. Public Health Implications. HIV and STI screening programs focused on CJI populations should be a priority for reducing HIV risk and numbers of undiagnosed infections among BMSM. Funding agencies and public health leaders should prioritize research to improve the knowledge base regarding which care continuum intervention approaches are most effective for BMSM with criminal justice involvement. Developments in modeling approaches could allow researchers to simulate the impacts and costs of criminal justice involvement-related interventions that might otherwise be cost, time, or ethically prohibitive to study empirically.

Understanding the impact of a syndemic on the use of pre-exposure prophylaxis in a community-based sample of behaviorally PrEP-eligible BMSM in the United States

HIV Pre-Exposure Prophylaxis (PrEP) has shown great promise in reducing HIV transmission among affected populations; however, PrEP uptake among Black men who have sex with men (BMSM) has stalled. This study compares BMSM using PrEP and BMSM at risk for HIV not using PrEP based on differences in behavior, psychosocial conditions and the presence of a syndemic (n = 1,411). BMSM reporting PrEP use were significantly more likely to report three of five HIV risk behaviors and three of four psychosocial conditions. Odds of reporting PrEP use increased as the number of psychosocial conditions increased such that BMSM with three psychosocial conditions (AOR = 5.65, 95% CI: 3.17, 10.08) and four conditions (AOR = 18.34, 95% CI: 5.01, 67.20) demonstrated significantly greater odds of PrEP use compared to BMSM reporting one or less conditions. While BMSM at greatest risk are using PrEP, strategies are still needed for men at varying risk levels.

The multiplex social environments of young Black men who have sex with men: How online and offline social structures impact HIV prevention and sex behavior engagement

In the United States, young Black men who have sex with men (YBMSM) remain disproportionately affected by HIV. The social networks in which YBMSM are embedded are generally understood to be critical factors in understanding their vulnerability. In this study, we acknowledge the relational richness of YBMSMs' social environments (what we define as multiplexity) and their increasing prioritization of online social networking sites (SNS). Specifically, we investigate whether protective and/or risky features of YBMSMs' Facebook friendships and group affiliations are related to their HIV prevention and sex behavior engagement, while also accounting for features of their offline confidant (or support) and sex networks. Using data from a population-based cohort study of YBMSM living in Chicago (N=268), we perform a series of multiple logistic regression analyses to examine associations between features of YBMSMs' Facebook, confidant, and sexual networks with three prevention outcomes and three sex behavior outcomes, while also controlling for factors at the individual and structural levels. Results show that network features play a more significant role in predicting engagement in sex behaviors than prevention behaviors. Specifically, having more confidants, having confidants who are family members, meeting sex partners online, having more YBMSM Facebook friends, belonging to Facebook groups with an LGBTQ focus, and having greater subject diversity in one's Facebook group affiliations were significantly associated with one or more sex behavior outcomes. We conclude with a discussion of the implications of our findings for HIV prevention intervention efforts.

Implementation of a Socio-structural Demonstration Project to Improve HIV Outcomes Among Young Black Men in the Deep South

BACKGROUND

We describe the background, rationale, intervention components, and formative results of a demonstration project aimed to ameliorate five socio-structural barriers to HIV services for young Black men aged 18-29 living with and at risk for HIV in Louisiana.

METHODS

The interventions and activities consisted of (1) five person-centered approaches to enhance linkage to HIV services and improve socio-economic outcomes; (2) the implementation of systematic mystery shopping tests to document instances of housing discrimination; (3) the development and implementation of a multi-prong communications campaign to increase knowledge about the signs of housing discrimination and community resources among young Black men who have sex with men (YBMSM); (4) the integration of HIV/STI services and lesbian, gay, bisexual, and trans (LGBT)-inclusive events on Historically Black Colleges and Universities (HBCUs); and (5) the development of a safe space for YBMSM. A multi-method approach was used to evaluate the outcomes of the different interventions.

RESULTS

The majority (62%) of participants living with HIV were linked to HIV care and 49% had achieved viral suppression. More than 40% of participants were employed during the project. Thirty-seven percent (37%) of the mystery shopping tests showed definite or possible signs of housing discrimination. The housing campaign's duration was limited with unknown long-term impact among YBMSM. Fifteen cases of syphilis were identified during two HBCU events. A safe space was specifically created for YBMSM at a community-based organization.

CONCLUSION

Multi-component holistic health interventions are needed to improve HIV outcomes and curb the high HIV rates among young Black men, particularly YBMSM in the United States and the Deep South.

Correlates of same-sex behavior disclosure to health care providers among Black MSM in the United States: implications for HIV prevention

Disclosure of same-sex behavior to health care providers (HCPs) by men who have sex with men (MSM) has been argued to be an important aspect of HIV prevention. However, Black MSM are less likely to disclose compared to white MSM. This analysis of data collected in the United States from 2006-2009 identified individual and social network characteristics of Black MSM (n = 226) that are associated with disclosure that may be leveraged to increase disclosure. Over two-thirds (68.1%) of the sample had ever disclosed to HCPs. Part-time employment (AOR = 0.32, 95% CI = 0.11-0.95), bisexual identity (AOR = 0.29, 95% CI = 0.12-0.70), and meeting criteria for alcohol use disorders (AOR = 0.32, 95% CI = 0.14-0.75) were negatively associated with disclosure. Disclosers were more likely to self-report being HIV-positive (AOR = 4.47, 95% CI = 1.54-12.98), having more frequent network socialization (AOR = 2.15, 95% CI = 1.24-3.73), and having a social network where all members knew the participant had sex with men (AOR = 4.94, 95% CI = 2.06-11.86). These associations were not moderated by self-reported HIV status. Future interventions to help MSM identify social network members to safely disclose their same-sex behavior may also help disclosure of same-sex behavior to HCPs among Black MSM.

Sexual Orientation Identity, Race/Ethnicity, and Lifetime HIV Testing in a National Probability Sample of U.S. Women and Men: An Intersectional Approach

Purpose: We examined differences in lifetime human immunodeficiency virus (HIV) testing in relation to both sexual orientation identity and race/ethnicity among U.S. women and men. Methods: We used 2013-2017 National Health Interview Survey data and multivariable logistic regression to assess the distribution of lifetime HIV testing across and within sexual orientation identity and racial/ethnic groups of U.S. women (n = 60,867) and men (n = 52,201) aged 18-64 years. Results: Among women, Black lesbian (74.1%) and bisexual (74.0%) women had the highest prevalence whereas Asian lesbian women (32.5%) had the lowest prevalence of lifetime HIV testing. Among men, the prevalence of lifetime HIV testing was the highest among Latino gay men (92.6%) and the lowest among Asian heterosexual men (32.0%). In most cases, Black women and Black and Latino men had significantly higher adjusted odds whereas Asian women and men had lower adjusted odds of lifetime HIV testing compared with their White counterparts within sexual orientation identity groups. In many instances, bisexual women and gay men had significantly higher adjusted odds of lifetime HIV testing relative to their heterosexual counterparts within racial/ethnic groups. Compared with White heterosexual individuals, most sexual orientation identity and racial/ethnic subgroups had significantly higher adjusted odds whereas Asian heterosexual, bisexual, and lesbian women and Asian heterosexual and bisexual men may have lower adjusted odds of lifetime HIV testing. Conclusion: Culturally relevant, linguistically appropriate, and structurally competent programs and practices are needed to facilitate lifetime HIV testing among diverse sexual orientation identity and racial/ethnic subgroups of women and men, including multiply marginalized subgroups that are undertested or disproportionately affected by HIV/AIDS.

HIV incidence among gay men and other men who have sex with men in 2020: where is the epidemic heading?

The goal to effectively prevent new HIV infections among gay, bisexual, and other men who have sex with men (MSM) is more challenging now than ever before. Despite declines in the late 1990s and early 2000s, HIV incidence among MSM is now increasing in many low- and high-income settings including the US, with young, adolescent, and racial/ethnic minority MSM being among those at highest risk. Potentiating HIV risks across all settings are individual-, network-, and structural-level factors such as stigma and lack of access to pre-exposure prophylaxis (PrEP) and antiretroviral treatment as prevention. To make a sustained impact on the epidemic, a concerted effort must integrate all evidence-based interventions that will most proximally decrease HIV acquisition and transmission risks, together with structural interventions that will support improved coverage and retention in care. Universal HIV treatment, increased access to HIV testing, and daily oral PrEP have emerged as integral to the prevention of HIV transmission, and such efforts should be immediately expanded for MSM and other populations disproportionately affected by HIV. Respect for human rights and efforts to combat stigma and improve access to prevention services are needed to change the trajectory of the HIV pandemic among MSM.

Viral suppression and HIV transmission behaviors among hospitalized patients living with HIV

From July 2012 to January 2014, the CTN0049 study, Project HOPE (Hospital Visit as Opportunity for Prevention and Engagement for HIV-infected Drug Users) interviewed 1227 people with HIV infection from 11 hospitals in the US to determine eligibility for participation in a randomized trial. Using these screening interviews, we conducted a cross-sectional study with multivariable analysis to examine groups that are at highest risk for having a detectable viral load (VL) and engaging in HIV transmission behaviors. Viral suppression was 42.8%. Persons with a detectable VL were more likely to have sex partners who were HIV-negative or of unknown status (OR = 1.72, 95% CI = 1.22–2.38), report not cleaning needles after injecting drugs (OR = 3.13, 95% CI = 1.33–7.14), and to engage in sex acts while high on drugs or alcohol (OR = 1.85, 95% CI = 1.28–2.7) compared to their counterparts. Many hospitalized people with HIV infection are unsuppressed and more likely to engage in HIV transmission behaviors than those with viral suppression. Developing behavioral interventions targeting HIV transmission behaviors toward patients with unsuppressed HIV VLs in the hospital setting has the potential to prevent HIV transmission.

Suboptimal Recent and Regular HIV Testing Among Black Men Who Have Sex With Men in the United States: Implications From a Meta-Analysis

BACKGROUND

The continuum of HIV care among black men who have sex with men (BMSM) continues to be the least favorable in the United States. BMSM are disproportionally HIV-infected-but-unaware, despite expanded HIV testing efforts among this subgroup.

METHODS

We meta-analytically analyzed various HIV testing patterns [lifetime, after 24 months, after 12 months, after 6 months, and frequent (every 3-6 months) testing] among BMSM using the PRISMA guideline. PubMed, MEDLINE, Web of Science, and PsycINFO were searched for relevant articles, reports, conference proceedings, and dissertations published between January 1, 1996, and April 25, 2018. Two independent investigators reviewed and abstracted data into a standardized form. We used the DerSimonian-Laird random-effect model to pool the HIV testing prevalence and I-square statistics to measure heterogeneity. Funnel plots and Egger tests were used to assess for publication bias. We also performed subgroup and meta-regression analyses to explore aggregate-level characteristics that explain the heterogeneity across studies.

RESULTS

Our meta-analysis includes a total of 42,074 BMSM pooled from 67 studies. Lifetime HIV testing prevalence was high, 88.2% [95% confidence interval (CI): 86.2% to 90.1%], but recent (after 6 months = 63.4%; 95% CI: 59.3% to 67.4%) and frequent (42.2%, 95% CI: 34.1% to 50.3%) HIV testing prevalence was low. Meta-regression suggests that younger age (borderline significant), lower annual income, and homelessness were correlated with lower lifetime/recent HIV testing prevalence; while ever having condomless insertive/receptive sex, alcohol consumption, and illicit drug use were associated with higher lifetime/recent HIV testing prevalence.

CONCLUSIONS

Recent and frequent HIV testing remains suboptimal among BMSM. Future testing programs should prioritize strategies to enhance self-initiated, regular HIV testing among BMSM.

The Association Between Condomless Anal Sex and Social Support Among Black Men Who Have Sex With Men (MSM) in Six U.S. Cities: A Study Using Data from the HIV Prevention Trials Network BROTHERS Study (HPTN 061)

We assessed how egocentric (i.e., self-generated descriptions of a person's social contacts) network structure and composition corresponded with reported instances of condomless receptive and insertive anal intercourse with men who were reportedly HIV-infected or of unknown HIV serostatus in a sample of black men who have sex with men (MSM) in six U.S. cities. Ratings showing a higher percentage of network members who provided social participation and medical support were positively associated with reporting condomless sex. There were also significant positive associations between stimulant use and condomless insertive and receptive anal sex. Future research should examine the social processes that underlie these associations and explore ways that social support can affect HIV prevention efforts for black MSM.

Using Financial Incentives to Improve Rates of Viral Suppression and Engagement in Care of Patients Receiving HIV Care at 3 Health Clinics in Louisiana: The Health Models Program, 2013-2016

OBJECTIVES

The Care and Prevention in the United States Demonstration Project aimed to reduce HIV/AIDS-related morbidity and mortality among racial/ethnic minority groups in 8 states. We evaluated Health Models, a pay-for-performance program piloted by the Louisiana Department of Health that used financial incentives to improve rates of engagement in HIV medical care and viral suppression among people with HIV.

METHODS

We enrolled 2076 patients of 3 urban HIV specialty clinics in Louisiana in the Health Models pay-for-performance program on a rolling basis from September 2013 through September 2016 and gave patients cash incentives to attend HIV medical appointments, achieve or maintain viral suppression, and link to supportive services. We used laboratory data collected from Louisiana's HIV surveillance database to calculate rates of engagement in care and viral suppression during the first 24 months of enrollment.

RESULTS

Of the 2076 patients who enrolled, 1400 (67.4%) were non-Hispanic black, 1480 (71.3%) were male, 1175 (56.6%) were men who have sex with men, and 1371 (66.0%) reported an annual income of <$15 000. At enrollment, 1456 (70.1%) patients were engaged in HIV care, and 1197 (57.7%) patients were virally suppressed. After 12 months of enrollment, 1474 of 1783 (82.7%) patients were virally suppressed. Of enrolled patients with at least 12 or 24 months of follow-up data, 1299 of 1317 (98.6%) patients were engaged in care during their first 12 months of enrollment, and 995 of 1033 (96.3%) patients were engaged in care between 12 and 24 months of enrollment.

CONCLUSIONS

During the implementation of Health Models, enrolled patients had increases in rates of viral suppression and achieved rates of engagement in care and viral suppression that were higher than national levels; however, additional supportive services may be needed to further reduce socioeconomic disparities in the rates of viral suppression.

Historical and Developmental Changes in Condom Use Among Young Men Who Have Sex with Men Using a Multiple-Cohort, Accelerated Longitudinal Design

Young men who have sex with men (YMSM) have the highest HIV incidence in the U.S. The last 5 years has seen emergence of new methods for HIV prevention and societal shifts in gay rights. It is important to understand if there have been generational shifts in condom use during the developmental transition from adolescents to young adulthood. To disentangle history from development, we require a multiple-cohort, longitudinal design-a methodology never before applied to study YMSM. We followed three cohorts of YMSM recruited in 2007, 2010, and 2015 (N = 1141) from the ages of 17-26 years and modeled their longitudinal change over time in counts of anal sex acts and the ratio of condomless anal sex (CAS) acts to anal sex acts using latent curve growth modeling. We found that there was no significant developmental change in raw counts of anal sex acts, but there was a significant decline in the ratio of anal sex acts that were condomless. We also found significantly different patterns for ratio of CAS acts for the 2015 cohort. The 2015 cohort reported a significantly lower ratio of CAS acts at age 17, but significantly higher growth in ratio of CAS acts over development. The present study suggests that YMSM recruited in 2015 have very different trajectories of CAS compared to previous cohorts, including lower risk in late adolescence, but with the potential for higher risk after the transition into adulthood.

A Longitudinal Examination of Factors Associated with Network Bridging Among YMSM: Implications for HIV Prevention

Social-environmental factors may be associated with social network stability, which has implications for HIV acquisition. However, the link between social-environmental factors, network composition and HIV risk has not been examined previously among a city-population based sample of young Black men who have sex with Men (YBMSM). Respondent driven sampling was used to recruit a cohort of 618 YMBSM. Respondents were evaluated at baseline, 9 and 18 months beginning June 2013. A logistic regression model was used to assess the relationship between bridging (i.e. having non-redundant contacts in one's network, indicating network instability) and social-environmental factors and HIV risk factors between respondents, and a conditional logit model was used to assess these relationships within respondents over time. Bridging was associated with adverse social-environmental factors and higher HIV risk, indicating that bridging may be on the explanatory pathway. Future studies should assess the extent to which network stability factors mitigate HIV risk.

A Randomized Trial of an Online Risk Reduction Intervention for Young Black MSM

HealthMpowerment.org (HMP), is a mobile optimized, online intervention to reduce sexual risk behaviors among HIV-positive and HIV-negative young Black men who have sex with men (BMSM) by providing information and resources, fostering social support, and including game-based elements. A randomized controlled trial with 474 young BMSM compared HMP to an information-only control website. The rate of self-reported condomless anal intercourse (CAI) at 3-months was 32% lower in the intervention group compared to the control group (IRR 0.68, 95% CI 0.43, 0.93), however this effect was not sustained at 12 months. Among HIV-positive participants, the rate of CAI at 3-month follow-up was 82% lower among participants with detectable viral loads in the intervention group compared to the control group (IRR 0.18, 95% CI 0.04, 0.32). In a secondary analysis, when we limited to those who used HMP for over 60 min during the 3-month intervention period (n = 50, 25.8%), we estimated 4.85 (95% CI 2.15, 7.53) fewer CAI events than we would have expected in control participants, had they used the intervention at the same rate as the intervention group. Findings suggest that exposure to an online intervention can reduce the rate of CAI among young BMSM, at least in the short term. Given the stronger effect seen among those participants who complied with HMP, additional intervention engagement strategies are warranted.

Social Network Support and Decreased Risk of Seroconversion in Black MSM: Results of the BROTHERS (HPTN 061) Study

BACKGROUND AND SETTING

Black men who have sex with men (BMSM) in the United States have disproportionately high HIV infection rates. Social networks have been shown to influence HIV risk behavior; however, little is known about whether they affect the risk of HIV seroconversion. This study uses data from the BROTHERS (HPTN 061) study to test whether contextual factors related to social networks are associated with HIV seroconversion among BMSM.

METHODS

We analyzed data from the BROTHERS study (2009-2011), which examined a multicomponent intervention for BMSM in 6 US cities. We ran a series of Cox regression analyses to examine associations between time-dependent measures of network support (personal/emotional, financial, medical, and social participation) and time to HIV seroconversion. We ran unadjusted models followed by models adjusted for participant age at enrollment and study location.

RESULTS

A total of 1000 BMSM tested HIV negative at baseline and were followed at 6- and 12-month study visits. Twenty-eight men tested HIV positive. In adjusted hazard ratio models, study participants who remained HIV negative had higher proportions of social network members who provided personal/emotional {0.92 [95% confidence interval (CI): 0.85 to 0.99]}, medical [0.92 (95% CI: 0.85 to 0.99)], or social participation [0.91 (95% CI: 0.86 to 0.97)] support.

CONCLUSION

Findings suggest that the increased presence of social network support can be protective against HIV acquisition. Future research should explore the processes that link social network support with sexual and other transmission risk behaviors as a basis to inform HIV prevention efforts.

Structural Barriers to Pre-exposure Prophylaxis Use Among Young Sexual Minority Men: The P18 Cohort Study

BACKGROUND

Despite decreasing rates of HIV among many populations, HIV-related health disparities among gay, bisexual and other men who have sex with men persist, with disproportional percentages of new HIV diagnoses among racial and ethnic minority men. Despite increasing awareness of HIV pre-exposure prophylaxis (PrEP), PrEP use remains low. In addition to exploring individual-level factors for this slow uptake, structural drivers of PrEP use must also be identified in order to maximize the effectiveness of biomedical HIV prevention strategies.

METHOD

Using cross-sectional data from an ongoing cohort study of young sexual minority men (N=492), we examine the extent to which structural-level barriers, including access to health care, medication logistics, counseling support, and stigma are related to PrEP use.

RESULTS

While almost all participants indicated awareness of PrEP, only 14% had ever used PrEP. PrEP use was associated with lower concerns about health care access, particularly paying for PrEP. Those with greater concerns talking with their provider about their sexual behaviors were less likely to use PrEP.

CONCLUSION

Paying for PrEP and talking to one's provider about sexual behaviors are concerns for young sexual minority men. In particular, stigma from healthcare providers poses a significant barrier to PrEP use in this population. Providers need not only to increase their own awareness of and advocacy for PrEP as an effective risk-management strategy for HIV prevention, but also must work to create open and non-judgmental spaces in which patients can discuss sexual behaviors without the fear of stigma.

HIV Education and Sexual Risk Behaviors Among Young Men Who Have Sex with Men

PURPOSE

Men who have sex with men (MSM) have nearly 80 times the lifetime risk of human immunodeficiency virus (HIV) relative to men who have sex with women only (MSW), and young MSM (YMSM) accounted for 95% of estimated HIV diagnoses among adolescents between 13 and 24 years in 2015. We aimed to evaluate HIV education and sexual risk behaviors among YMSM relative to young MSW (YMSW) and to evaluate the relationship between HIV education and YMSM sexual risk behaviors.

METHODS

We used Youth Risk Behavior Surveillance System data from 13 states that collected information on sex of sexual contacts and on HIV education in 2011 and/or 2013. We assessed HIV education, number of sexual partners ever and in the past three months, and condom use at last sex in logistic regression analyses controlling for age, race/ethnicity, state, and year.

RESULTS

YMSM were less likely to report school-based HIV education and more likely to report sexual risk behaviors relative to YMSW. HIV education was associated with reduced sexual risk behaviors among all students and with significant additional reductions in sexual risk behaviors among YMSM.

CONCLUSION

There is a need for HIV education programs to reach YMSM, who are at increased risk of HIV.

Sexual Partner Characteristics, Relationship Type, and HIV Risk Among a Community Venue-based Sample of Urban Adolescent and Young Adult Men Who Have Sex with Men

Few studies have examined sexual partnerships and HIV risk in diverse samples of African American/black and Hispanic/Latino adolescent and young adult men who have sex with men (YMSM), a group that have a high burden of HIV in the U.S. A community-venue recruitment approach was used, which identified significant differences in HIV risk by sexual partner type among 1215 YMSM. Those with casual partners had a higher number of sexual partners, had more STIs, and were more likely to engage in transactional sex, to use alcohol, marijuana, or other substances compared with those with main partners only. Among those with female sexual partners, many used condoms "every time" when engaging in vaginal sex with casual partners, but a sizeable proportion "never/rarely" used condoms with their main partners. Our findings demonstrate a need for tailored HIV prevention education and counseling with necessary skills regarding consistent and correct condom use with all sexual partnerships.

Exposure to community violence and substance use among Black men who have sex with men: examining the role of psychological distress and criminal justice involvement

Young Black MSM (YBMSM) are disproportionately affected by violence, criminal justice involvement, and other structural factors that also increase vulnerability to HIV. This study examined associations between exposure to community violence (ECV) and substance use, psychological distress, and criminal justice involvement (CJI) among YBMSM in Chicago, IL. Respondent driven sampling was used to recruit a sample of 618 YBMSM (aged 16-29) from the South Side of Chicago between June 2013 and July 2014. Weighted logistic regression assessed the direct effects of ECV, CJI, and psychological distress on substance use outcomes. Indirect effects were assessed via path analysis with mean and variance adjusted weighted least squares estimation and sampling weights. Over 90% reported lifetime exposure to violence, 41% had history of CJI, and substance use was common. Almost one-third reported daily or more frequent marijuana use; 17% reported substance use related problems and drug use other than marijuana. ECV was directly and positively associated with CJI, psychological distress, and problematic substance use, with significant indirect effects from ECV to⁠ problematic substance use via CJI and psychological distress. HIV prevention interventions for YBMSM should address the underlying contextual drivers of substance use and psychological distress, including violence exposure and criminal justice involvement.

Sexual Networks of Racially Diverse Young MSM Differ in Racial Homophily But Not Concurrency

BACKGROUND

Substantial racial disparities exist in HIV infection among young men who have sex with men (YMSM). However, evidence suggests black YMSM do not engage in greater levels of risk behavior. Sexual networks may help explain this paradox. This study used egocentric exponential random graph models to examine variation in concurrency (ie, 2 or more simultaneous partners) and homophily (ie, same race/ethnicity partners) across race/ethnicity groups in a diverse sample of YMSM.

METHODS

Data for this study come from a longitudinal cohort study of YMSM. Participants (n = 1012) provided data regarding their sexual contacts during the 6 months before their first study visit. A series of egocentric exponential random graph models examined how providing separate estimates for homophily and concurrency parameters across race/ethnicity improved the fit of these models. Networks were simulated using these parameters to examine how local network characteristics impact risk at the whole network level.

RESULTS

Results indicated that homophily, but not concurrency, varied across race/ethnicity. Black participants witnessed significantly higher race/ethnicity homophily compared with white and Latino peers. Extrapolating from these models, black individuals were more likely to be in a connected component with an HIV-positive individual and closer to HIV-positive individuals. However, white individuals were more likely to be in large connected components.

CONCLUSIONS

These findings suggest that high racial homophily combined with existing disparities in HIV help perpetuate the spread of HIV among black YMSM. Nonetheless, additional work is required to understand these disparities given that homophily alone cannot sustain them indefinitely.

Reframing masculinity: structural vulnerability and HIV among black men who have sex with men and women

This paper calls for a critical reframing of masculinity as an intersectional construct in the HIV epidemic and in public health. In-depth qualitative interviews were conducted with a sample of 56 Black men who have sex with men and women in the San Francisco Bay Area. Men described their sexual identities and practices via complex narratives of masculinity that drew on subordinated and resourceful adaptations to the structural effects of racism, economic marginalisation and homophobia. By focusing on men whose experience of masculinity operates outside fixed identity categories, the paper draws attention to the intersectionality that is, by necessity, constitutive of men's lived experiences. Findings suggest the value of an integrative framework for understanding Black masculinities as processes and practices simultaneously informed by structural inequalities (racism, economic marginalisation and/or homophobia, in particular) and cultural meanings of gender. By utilising an intersectional approach, public health and sociology can better understand the concurrent resilience and vulnerability of masculinities, while building an interdisciplinary understanding of the symbolic role of Black masculinities in the USA, as well as a means by which to promote health and well-being in and through these gendered contexts.

Behavioral characteristics and their association with syphilis seroprevalence among a cohort of young Black men who have sex with men

The objective of this study was to describe the sociodemographic characteristics and behavioral factors that are associated with syphilis seroprevalence in a cohort of young Black men who have sex with men (YBMSM) in Chicago, USA (n = 606). The weighted syphilis seroprevalence in the study population was 29.2% (95% CI 23.9, 35.1). A bivariate probit multiple regression model was used to estimate the outcomes. Characteristics that were positively associated with syphilis seropositivity included being age 19-20, 21-24, and at least age 25 compared to the reference group (age 16-18 years old) (0.72 [95% CI 0.18, 1.25], 1.40 [95% CI 0.68, 2.13], and 1.34 [95% CI 0.75,1.94], respectively), using social media to meet sexual partners (0.33 [95% CI 0.05, 0.61]), using condoms more often (0.39 [95% CI 0.02, 0.76]), and a history of criminal justice involvement (0.25 [95% CI 0.06, 0.44]). Our study results suggest that among YBMSM in Chicago, interventions promoting condom use may be less effective for syphilis prevention compared to HIV prevention in this population. The contribution of nonpenetrative sex to syphilis prevalence requires additional research as does how best to implement routine syphilis screening and treatment for YBMSM in the context of ongoing syphilis transmission.

An Investigation of Racial and Ethnic Homophily on Grindr Among an Ongoing Cohort Study of YMSM

Men who have sex with men (MSM), and especially MSM of color, are disproportionately affected by HIV. Previous research shows that MSM have high levels of racial/ethnic homophily (the tendency for people to have sex with others who share the same racial/ethnic identification) in sexual dyads, which may help explain HIV disparities. This study fills a gap in previous research by grounding network data from a cohort study of young MSM in Chicago (RADAR) in the contexts of virtual spaces (VSs) and examining differences in levels of racial/ethnic homophily using multilevel-logistic-regression models. Results show that Grindr differs from other VSs in proportions of racially/ethnically homophilous dyads and by partner racial/ethnic identification. After controlling for general homophily trends, sex partnerships formed on Grindr by Black MSM were significantly less likely to be homophilous than those of White MSM. While racial/ethnic groups differ in likelihood to form homophilous partnerships, this trend varies by VS.

Associations between sociodemographic characteristics and substance use disorder severity among methamphetamine-using men who have sex with men

Background: Men who have sex with men (MSM) have elevated rates of substance use disorders (SUDs) and differences across sociodemographic sub-groups of MSM are associated with a greater risk of deleterious outcomes. Although studies have shown that MSM report greater rates of polysubstance use relative to other adult populations, the associations between sociodemographic characteristics and both acute substance use and substance use severity among methamphetamine-using MSM are unknown. Objectives: The present study examines associations between sociodemographic characteristics and (a) recent substance use and (b) SUD severity. Method: From March 2014 to January 2016, 286 methamphetamine-using MSM were recruited to complete a baseline Audio Computer-Assisted Self-Interview (ACASI) assessment and the SCID MINI. Multivariable analyses employed generalized structural equation modeling given the non-continuous nature of the endogenous variables. Results: All measured sociodemographic characteristics except gay self-identification were significantly associated with recent substance use (all ps ≤ .05), and all characteristics except current homelessness were significantly associated with diagnostic SUD severity (all ps ≤ .05). However, nuanced risks were observed in participants' use of specific substances regarding recent substance use and substance use severity. Conclusion: These results suggest that multiple factors contribute to the risks of SUD severity among methamphetamine-using MSM. As such, these results are useful in the tailoring of clinical and psychosocial intervention strategies that serve this and other high-risk populations.

Sex Venue-Based Network Analysis to Identify HIV Prevention Dissemination Targets for Men Who Have Sex with Men

PURPOSE

The aim of this study was to identify sex venue-based networks among men who have sex with men (MSM) to inform HIV preexposure prophylaxis (PrEP) dissemination efforts.

METHODS

Using a cross-sectional design, we interviewed MSM about the venues where their recent sexual partners were found. Venues were organized into network matrices grouped by condom use and race. We examined network structure, central venues, and network subgroups.

RESULTS

Among 49 participants, the median age was 27 years, 49% were Black and 86% reported condomless anal sex (ncAS). Analysis revealed a map of 54 virtual and physical venues with an overlap in the ncAS and with condom anal sex (cAS) venues. In the ncAS network, virtual and physical locations were more interconnected. The ncAS venues reported by Blacks were more diffusely organized than those reported by Whites.

CONCLUSION

The network structures of sex venues for at-risk MSM differed by race. Network information can enhance HIV prevention dissemination efforts among subpopulations, including PrEP implementation.

A qualitative exploration of facilitators and barriers to meningitis vaccination uptake among men who have sex with men

Invasive Meningococcal Disease is a deadly, but preventable disease, with community outbreaks occurring at rate of 9.5 per year. Serogroup C Invasive Meningococcal Disease (IMD) community outbreaks in men who have sex with men (MSM) have been reported with greater frequency in large urban areas since 2010. An effective vaccine exists that can temper and control outbreaks, and is recommended for MSM in outbreak settings; however very little is known about the perceptions, barriers and facilitators to IMD vaccine uptake among MSM. Optimizing awareness and vaccine uptake for MSM is a high priority to reduce and control IMD outbreaks. To that end, we conducted focus groups with MSM during an active IMD outbreak to inform development of a tailored intervention strategy. Participants discussed facilitators (e.g., logistics, relationships, health literacy) and barriers (e.g., fear of disclosure, medical distrust) to vaccination, as well as ideas for intervention strategies (e.g., incentives, use of internet outreach).

Sexual, Social, and Genetic Network Overlap: A Socio-Molecular Approach Toward Public Health Intervention of HIV

OBJECTIVES

To determine how network-level factors influence individual risk of HIV acquisition, which is key in preventing disease transmission.

METHODS

We recruited a cohort of young Black men who have sex with men (n = 618) in Chicago, Illinois, from 2013 to 2016. We identified potential molecular ties via pairwise genetic distance analysis of HIV pol sequences with links inferred between individuals whose sequences were 1.5% or less genetically distant. We defined clusters as 1 or more connections to another individual. We conducted entity resolution between confidant, sexual, referral, and Facebook network data between network types.

RESULTS

Of 266 (43.0%) participants identified as HIV-positive, we obtained 86 (32.3%) genetic sequences. Of these, 35 (40.7%) were linked to 1 or more other sequence; however, none of these were identified in first-, second-, or third-degree confidant and sexual networks. Minimal overlap existed between genetic and Facebook ties.

CONCLUSIONS

These results suggest that HIV transmissions may have occurred before elicitation of network data; future studies should expand the data collection timeframe to more accurately determine risk networks. Virtual network data, such as Facebook, may be particularly useful in developing one's risk environment.

State of HIV in the US Deep South

The Southern United States has been disproportionately affected by HIV diagnoses and mortality. To inform efforts to effectively address HIV in the South, this manuscript synthesizes recent data on HIV epidemiology, care financing, and current research literature on factors that predispose this region to experience a greater impact of HIV. The manuscript focuses on a specific Southern region, the Deep South, which has been particularly affected by HIV. Epidemiologic data from the Centers from Disease Control and Prevention indicate that the Deep South had the highest HIV diagnosis rate and the highest number of individuals diagnosed with HIV (18,087) in 2014. The percentage of new HIV diagnoses that were female has decreased over time (2008-2014) while increasing among minority MSM. The Deep South also had the highest death rates with HIV as an underlying cause of any US region in 2014. Despite higher diagnosis and death rates, the Deep South received less federal government and private foundation funding per person living with HIV than the US overall. Factors that have been identified as contributors to the disproportionate effects of HIV in the Deep South include pervasive HIV-related stigma, poverty, higher levels of sexually transmitted infections, racial inequality and bias, and laws that further HIV-related stigma and fear. Interventions that address and abate the contributors to the spread of HIV disease and the poorer HIV-related outcomes in the Deep South are warranted. Funding inequalities by region must also be examined and addressed to reduce the regional disparities in HIV incidence and mortality.
