Associations of past-year stigma and psychosocial syndemic conditions: Considerations for intersectional stigma measures among Black Sexual Minority Men.

This secondary analysis of a mixed serostatus sample of Black sexual minority men (BSMM) used conditional inference tree methods to explore associations of past-year experienced stigma and psychosocial syndemic conditions. Experienced stigmas were attributed to race, sexuality, socioeconomic status, HIV status or some "other" reason. Psychosocial syndemic conditions studied included physical assault, intimate partner violence, polysubstance use, and depression symptomology. Data are from Promoting Our Worth, Equality and Resilience (POWER), a serial, cross-sectional study conducted between 2014-2017 (N=4430). Experiences of multiple stigmas were reported by n=938 (22.1%) of BSMM. Conditional inference tree results revealed that HIV-related stigma and its intersection with "other" stigma showed the greatest variance in psychosocial condition prevalence. Our findings suggest that when developing intercategorical intersectional analyses with BSMM, there are important stigmas for BSMM beyond those attributed to race, sexuality, and SES, particularly intersecting with HIV-related stigma. Conditional inference tree analysis shows promise in quantitative explorations of intersectional stigma with BSMM, but will benefit from the inclusion of additional forms of stigma, which should be considered by the field moving forward.

Intersectional Experienced Stigma and Psychosocial Syndemic Conditions in a Sample of Black Men Who Have Sex with Men Engaged in Sex Work (BMSM-SW) from Six US Cities.

Black men who have sex with men (BMSM) in the United States experience a disproportionate burden of violence, substance use, physical and mental health conditions relative to other racial groups. BMSM who engage in sex work (BMSM-SW) experience a high burden of psychosocial conditions, sexually transmitted infections, including HIV, and intersectional stigma. This analysis characterizes remuneration and client typologies for BMSM-SW, documents intersectional stigma experienced by BMSM-SW relative to other BMSM, and explores the impact of experienced intersectional stigma on the relationship between sex work engagement and psychosocial syndemic conditions (violence, polydrug use, and depression symptoms). Results show that a majority of BMSM-SW in the sample had female clients and that sex workers were more likely than other BMSM to hire another sex worker. BMSM-SW were more likely than other BMSM to report stigma attributed to race; sexuality; HIV status; socioeconomic status; and "other" attributes, and were more likely to report experiencing stigma across all settings assessed (schools; healthcare; employment; housing; police/courts; and in public/community). Intersectional stigma mediated the relationship between sex work engagement and psychosocial syndemic conditions, accounting for 49% (95% CI: 47.6-50.0%) of the relationship. Interventions for BMSM-SW should include resilience-building components to counteract the effects of intersectional stigma.

Characterizing Biomedical HIV Prevention Awareness and Use Among Black Transgender Women in the United States.

Black transgender women (BTW) in the United States experience disproportionate rates of HIV despite biomedical prevention interventions such as pre-exposure prophylaxis (PrEP) and non-occupational post-exposure prophylaxis (nPEP). Using a sample of 490 BTW collected from 2014 to 2017, bivariate, multivariable, and multinomial analyses were conducted to determine factors associated with awareness and use of PrEP and nPEP. BTW living with HIV were more aware of PrEP than HIV-negative BTW. Structural, demographic, and trans-specific factors (e.g., experiences of homelessness, violence, and current hormone use) related to HIV risk were associated with PrEP and nPEP awareness. PrEP use was associated with behavioral HIV risks (e.g., STI diagnosis, having an HIV-positive partner, and needle-sharing) and may demonstrate risk recognition among BTW. Knowing someone using PrEP was significantly positively associated with PrEP use. Development of guidelines for PrEP and nPEP use for BTW should leverage the strengths of guidelines for other populations, while also acknowledging the unique risks for this population.

Syndemic Health Disparities and Sexually Transmitted Infection Burden Among Black Men Who Have Sex with Men Engaged in Sex Work in the U.S.

Black men who have sex with men (MSM) engaged in sex work (BMSM-SW) experience elevated HIV and sexually transmitted infection (STI) prevalence. Further, BMSM-SW have been shown to have higher rates of syndemic psychosocial health conditions which contribute to HIV risk behavior and incidence, and poorer care outcomes than other groups of men who have sex with men. However, syndemic perspectives have not been applied to understanding past-year STI burden among BMSM-SW in the U.S. Sexually active Black MSM ≥ 18 years old were recruited from Black Pride events in six U.S. cities (n = 4421) between 2014 and 2017. Multivariable logistic regressions assessed correlates of past-year sex work engagement; whether BMSM-SW had higher odds of syndemic conditions; and whether BMSM-SW had higher odds of self-reported, past-year STI diagnoses. Structural equation models assessed relationships between sex work engagement, syndemic conditions, and STI controlled for sociodemographics and number of sexual partners. A total of 254 (5.7%) Black MSM reported past-year sex work, of whom 45.3% were HIV positive. BMSM-SW were significantly more likely to be Hispanic, to report past-year bisexual behavior, and to report annual income < $10,000. In multivariable models, BMSM-SW were significantly more likely to report intimate partner violence, assault victimization, polydrug use, and depression symptoms; they were also more likely to report past-year gonorrhea, chlamydia, and syphilis. Syndemic conditions mediated the relationship between past-year sex work and past-year STI burden, constituting a significant indirect effect. BMSM-SW in the U.S. face severe biopsychosocial health disparities. Interventions developed for BMSM engaged in sex work are lacking. Our results suggest that interventions containing safer sex work education and sex-positive biobehavioral HIV/STI prevention alongside substance use, mental health, employment, and education components will be most effective.

Barriers and facilitators to past six-month HIV testing among men who have sex with men in Belize.

Prevalence of HIV in Belize is high, and men who have sex with men (MSM) are disproportionately impacted by HIV. HIV testing is critical in curbing the epidemic; however, little is known about factors associated with testing among MSM in Belize. Working with a non-governmental organization in a large, urban city within Belize, snowball sampling was applied to recruit Belizean MSM to complete a self-administered survey. Multivariable logistic regression analysis was employed to understand associations with HIV screening behavior. Access to healthcare, HIV knowledge, and reporting having heard of Section 53 of the Criminal Code of Belize (once outlawing same-sex sexual behavior), but not experiencing any negative impact from Section 53 were significantly positively associated with having received an HIV test in the past six months. Healthcare maltreatment (lifetime), depression symptomology, and shame were significantly negatively associated with having received a HIV test in the past six months. Findings suggest that multiple factors associated with stigma and discrimination negatively affect testing strategies among MSM in Belize.

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.

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.

Police killings of Black people and rates of sexually transmitted infections: a cross-sectional analysis of 75 large US metropolitan areas, 2016.

OBJECTIVES: Emerging literature shows that racialised police brutality, a form of structural racism, significantly affects health and well-being of racial/ethnic minorities in the USA. While public health research suggests that structural racism is a distal determinant of sexually transmitted infections (STIs) among Black people, no studies have empirically linked police violence to STIs. To address this gap, our study measures associations between police killings and rates of STIs among Black residents of US metropolitan statistical areas (MSAs). METHODS: This cross-sectional ecological analysis assessed associations between the number of Black people killed by police in 2015 and rates of primary and secondary syphilis, gonorrhoea and chlamydia per 100 000 Black residents of all ages in 2016 in 75 large MSAs. Multivariable models controlled for MSA-level demographic and socioeconomic characteristics, police expenditures, violent crime, arrest and incarceration rates, insurance rates and healthcare funding. RESULTS: In 2015, the median number of Black people killed by police per MSA was 1.0. In multivariable models, police killings were positively and significantly associated with syphilis and gonorrhoea rates among Black residents. Each additional police killing in 2015 was associated with syphilis rates that were 7.5% higher and gonorrhoea rates that were 4.0% higher in 2016. CONCLUSIONS: Police killings of Black people may increase MSA-level risk of STI infections among Black residents. If future longitudinal analyses support these findings, efforts to reduce STIs among Black people should include reducing police brutality and addressing mechanisms linking this violence to STIs.

States with higher minimum wages have lower STI rates among women: Results of an ecological study of 66 US metropolitan areas, 2003-2015.

Prior research has found that places and people that are more economically disadvantaged have higher rates and risks, respectively, of sexually transmitted infections (STIs). Economic disadvantages at the level of places and people, however, are themselves influenced by economic policies. To enhance the policy relevance of STI research, we explore, for the first time, the relationship between state-level minimum wage policies and STI rates among women in a cohort of 66 large metropolitan statistical areas (MSAs) in the US spanning 2003-2015. Our annual state-level minimum wage measure was adjusted for inflation and cost of living. STI outcomes (rates of primary and secondary syphilis, gonorrhea and chlamydia per 100,000 women) were obtained from the CDC. We used multivariable hierarchical linear models to test the hypothesis that higher minimum wages would be associated with lower STI rates. We preliminarily explored possible socioeconomic mediators of the minimum wage/STI relationship (e.g., MSA-level rates of poverty, employment, and incarceration). We found that a $1 increase in the price-adjusted minimum wage over time was associated with a 19.7% decrease in syphilis rates among women and with an 8.5% drop in gonorrhea rates among women. The association between minimum wage and chlamydia rates did not meet our cutpoint for substantive significance. Preliminary mediation analyses suggest that MSA-level employment among women may mediate the relationship between minimum wage and gonorrhea. Consistent with an emerging body of research on minimum wage and health, our findings suggest that increasing the minimum wage may have a protective effect on STI rates among women. If other studies support this finding, public health strategies to reduce STIs among women should include advocating for a higher minimum wage.

HIV Testing and ART Adherence Among Unstably Housed Black Men Who Have Sex with Men in the United States.

Black men who have sex with men (BMSM) have the highest HIV incidence rate among all MSM in the United States (US), and are also disproportionately affected by homelessness and housing instability. However, little is known about the effects of homelessness on the HIV testing and care continuum for BMSM. Between 2014 and 2017, the Promoting Our Worth, Equality, and Resilience (POWER) study collected data and offered HIV testing to 4184 BMSM at Black Pride events in six US cities. Bivariate analyses were used to assess differences in sociodemographics and healthcare access between BMSM who self-reported homelessness and those who did not. Multivariable logistic regression models were used to assess differences in HIV testing by homelessness status. Finally, bivariate and multivariable models were used to assess differences in HIV care continuum and treatment adherence outcomes by homelessness status. 615 (12.1%) BMSM in our sample experienced homelessness in the last 12 months. BMSM who self-reported homelessness had higher odds of receiving an HIV test in the past 6 months compared to their stably housed counterparts. BMSM who self-reported homelessness had higher odds of reporting difficulty taking ART and of missing a dose in the past week compared to stably housed BMSM. Findings suggest that HIV testing outreach and treatment-related services targeting unstably housed BMSM may be effective. Future community-based research is needed to investigate how homelessness and housing instability affect ART adherence, and how this population may experience success in HIV testing and adherence despite economic and social marginalization.

Intimate Partner Violence and Depression among Black Transgender Women in the USA: The Potential Suppressive Effect of Perceived Social Support.

Depression among Black transgender women (BTW) in the USA is an often understudied mental health concern with far-reaching consequences for overall physical and mental health at both the individual and community levels. Intimate partner violence (IPV) among BTW is also a frequently understudied and important social determinant of health in need of further exploration. This study sought to address the gap in research on the relationship between IPV and depression among BTW using a time- and location-based community sample of BTW from six US cities. In addition, it sought to explore the potential protective or suppressive effect of perceived social support on this relationship. Generalized structural equation models were used to assess conditional direct and indirect effects of IPV on depression via the suppression effect of perceived social support. Evidence was found of a statistically significant conditional direct effect of IPV on depression as well as a statistically significant suppression effect for perceived social support. Specifically, there was a 20% lower likelihood of increased depressive symptomatology for every 1-unit increase in perceived social support reported by participants. These findings indicated that perceived social support may be an important intervention point for helping to improve the mental health and well-being of BTW.

Characterizing the HIV care continuum among a community sample of black men who have sex with men in the United States.

Black men who have sex with men (BMSM) have the highest HIV incidence rates among all men who have sex with men (MSM) and have been less likely than other MSM to be diagnosed, linked or retained in care for HIV. The Promoting Our Worth, Equality, and Resilience (POWER) study administered a behavioral health survey and HIV test to BMSM to estimate the HIV continuum of care among a community-derived sample. Of the N = 1,680 BMSM living with HIV, n = 956 (56.9%) were aware of their HIV-positive status. BMSM who had been previously diagnosed reported progression through the care continuum at greater than 80% for linkage to medical care (97.6%), retention in medical care (97.3%), prescription of antiretroviral therapy (93.6%) and viral suppression (86.4%). Results of this analysis reveal the urgent need to ensure BMSM are being screened and diagnosed. Additionally, community-driven samples are a promising method offering the opportunity to build on the resilience of BMSM progressing though the continuum as well as engage BMSM not yet in care. Lastly, such methods can assist in communicating with those lost to retention.

Approaches to Identify Unknown HIV-Positive Men Who Have Sex with Men in Nairobi, Kenya.

Kenya has been home to one of the most severe HIV/AIDS epidemics in Sub-Saharan Africa. This persistent epidemic requires interventions tailored to affected populations, particularly men who have sex with men (MSM). Given the resource constraints of many clinics and ecological challenges of Kenya, such as the illegality of sex among MSM, interventions to address HIV must strategically engage this population. This quasi-experimental pilot study of N = 497 sought to explore differences in discovering previously unknown HIV-positive MSM in Nairobi, Kenya. The study used four clinical sites to compare a social and sexual network index testing (SSNIT) strategy compared to traditional HIV screening. Clinics using the SSNIT strategy had significantly higher incidence rates of HIV diagnoses than control clinics (IRR = 3.98, p < 0.001). This study found that building upon the social and sexual networks of MSM may be one promising strategy while discovering critical cases of HIV.

Characterizing the HIV Care Continuum and Identifying Barriers and Facilitators to HIV Diagnosis and Viral Suppression Among Black Transgender Women in the United States.

BACKGROUND: Although black transgender women (BTW) experience high prevalence of HIV in the United States, no characterization of the HIV care continuum exists for this population. This study addresses this gap by (1) characterizing the HIV care continuum, and (2) exploring correlates of HIV diagnosis and viral suppression among a community-based sample of BTW. METHODS: Data came from Promoting Our Worth, Equality, and Resilience (POWER). From 2014 to 2017, POWER recruited BTW who attended Black Pride events in 6 U.S. cities. Participants completed a behavioral health survey and were offered onsite HIV testing. Simple frequencies were used to characterize the HIV care continuum, and multivariable logistic regression analysis was used to identify correlates of HIV diagnosis and viral suppression. RESULTS: A total of 422 BTW provided completed data for our analysis, 45.0% of whom were living with HIV. Over half of the HIV-positive BTW (51.4%) reported being undiagnosed at the time of survey, and 24.5% reported viral suppression. Incarceration and a lack of access to medical care were significantly and positively associated with an undiagnosed HIV-positive status in multivariable models. Incarceration, homelessness, polydrug use, physical assault, intimate partner violence, and current hormone use were significantly and negatively associated with viral suppression in multivariable models. CONCLUSIONS: Developing and implementing interventions that address timely HIV diagnosis may assist in informing the HIV disparity among BTW in the United States. Interventions should address the fundamental causes of poor health in this population.

Drug Use, Sexual Risk, and Syndemic Production Among Men Who Have Sex With Men Who Engage in Group Sexual Encounters.

OBJECTIVES: We surveyed men who have sex with men (MSM) to determine whether sexual risk behaviors, recent drug use, and other psychosocial problems differed between men who engaged in one-on-one and group sexual encounters. METHODS: We conducted an Internet-based cross-sectional survey of 7158 MSM aged 18 years or older in the United States recruited from a gay-oriented sexual networking Web site in 2008. Among MSM who engaged in group sexual encounters, we compared their past-60-day sexual behaviors in one-on-one encounters and group sexual encounters. We also compared risk profiles and syndemic production between men who did and did not participate in group sex. RESULTS: Men reporting a group-sex encounter had significantly higher polydrug use and sexual risk than did the men not reporting group sex in the past 60 days. The odds of engaging in group sex with 4 or more sexual partners significantly increased with the number of psychosocial problems, supporting evidence of syndemic production. CONCLUSIONS: We identified a particularly high-risk subgroup in the MSM population with considerable psychosocial problems that may be reached online. Research is needed on how to engage these high-risk men in combination prevention interventions.

A randomized trial of a behavioral intervention for high risk substance-using MSM.

Substance-using men who have sex with men (MSM) are among the groups at highest risk for HIV infection in the United States. We report the results of a randomized trial testing the efficacy of a small group sexual and substance use risk reduction intervention based on empowerment theory compared to an enhanced efficacious control condition among 515 high risk not-in-treatment MSM substance users. Effect sizes for sexual risk and substance use outcomes were moderate to large: HIV transmission risk frequency, d = 0.71 in the control versus 0.66 in the experimental group; number of anal sex partners, d = 1.04 versus 0.98; substance dependence symptoms, d = 0.49 versus 0.53; significant differences were not observed between conditions. Black MSM reduced their risks at a greater rate than White or Latino men. The findings point to a critically important research agenda to reduce HIV transmission among MSM substance users.

Joint effects of alcohol consumption and high-risk sexual behavior on HIV seroconversion among men who have sex with men.

OBJECTIVE: To estimate the effects of alcohol consumption and number of unprotected receptive anal intercourse partners on HIV seroconversion while appropriately accounting for time-varying confounding. DESIGN: Prospective cohort of 3725 HIV-seronegative men in the Multicenter AIDS Cohort Study between 1984 and 2008. METHODS: Marginal structural models were used to estimate the joint effects of alcohol consumption and number of unprotected receptive anal intercourse partners on HIV seroconversion. RESULTS: Baseline self-reported alcohol consumption was a median 8  drinks/week (quartiles: 2, 16), and 30% of participants reported multiple unprotected receptive anal intercourse partners in the prior 2 years. Five hundred and twenty-nine HIV seroconversions occurred over 35 ,870 person-years of follow-up. After accounting for several measured confounders using a joint marginal structural Cox proportional hazards model, the hazard ratio for seroconversion associated with moderate drinking (1-14 drinks/week) compared with abstention was 1.10 [95% confidence limits: 0.78, 1.54] and for heavy drinking (>14 drinks/week) was 1.61 (95% confidence limits: 1.12, 2.29) (P for trend <0.001). The hazard ratios for heavy drinking compared with abstention for participants with 0-1 or more than 1 unprotected receptive anal intercourse partner were 1.37 (95% confidence limits: 0.88, 2.16) and 1.96 (95% confidence limits: 1.03, 3.72), respectively (P for interaction = 0.42). CONCLUSION: These findings suggest that alcohol interventions to reduce heavy drinking among men who have sex with men should be integrated into existing HIV prevention activities.
