Assessing HIV Stigma on Prevention Strategies for Black Men Who Have Sex with Men in the United States

Geometric approach to measuring intersectional stigma among black sexual minority men: reliability and validity in an HIV prevention context

BACKGROUND

Stigma and discrimination experiences attributable to multiple intersecting facets of the self (e.g. intersectional stigma) pose substantial challenges to accessing health services, including HIV prevention. While there have been theoretical advances in understanding multiple co-occurring stigmas, there are few psychometric instruments available to assess intersectional stigma. We have developed an approach to assessing intersectional stigma that conceptualises an intersection in geometric terms, defined as the line that connects points on two (or more) stigma dimensions and calculates scores derived from the geometric definition of intersecting lines.

METHODS

Following pilot studies to derive items and response formats, we administered newly developed enacted stigma (24-items) and anticipated stigma (17-items) scales with attributions to race and sexual minority status for stigma experiences to a sample of 422 Black sexual minority men at risk for HIV recruited through social media platforms.

RESULTS

The enacted and anticipated intersectional stigma scales, including subscales representing discrimination, interpersonal and felt stigma demonstrated evidence for reliability and construct validity. The enacted stigma scales were associated with medical mistrust, whereas the anticipated stigma scales predicted perceived barriers to using pre-exposure prophylaxis for HIV prevention.

CONCLUSIONS

The intersectional stigma scales offer greater specificity in measuring stigma experiences attributed to race, sexual minority status and the intersection of racial-sexual minority status.

Effects of Online Friendships on Safer Sex Communication and Behavior among Black Sexual Minority Men: A Study of Network Exposure

This study draws on social normative and social learning theories to examine the masspersonal safer sex communication (i.e., Facebook posts about safer sex) and safer sex behavior (i.e., condom use) in a cohort of Black sexual minority men (BSMM) (N = 340), with an eye toward understanding their relationship with the safer sex communication and behaviors of their BSMM Facebook friends. Using linear network autocorrelation regression models, results showed that BSMM's safer sex communication and condom use behavior were each associated with the communication and behavior of their online peers. Specifically, BSMM's condom use was positively associated with their friends' condom use and friends' safer sex communication, and BSMMs' safer sex communication was positively associated with friends' safer sex communication. Moreover, contrary to prior research, BSSM's safer sex communication and condom use were not related to one another, suggesting that talking about safer sex on social media should not be interpreted to be an indication of engageDment in safer sex behavior. These findings underscore an opportunity to leverage peer influence in social media networks, particularly in the form of masspersonal communication, to encourage cascades of safer sex messaging among peers and adoption of safer sex behavior.

The Ongoing Process of HIV-Stigma (Re)Production

HIV stigma negatively affects the social experiences of people living with HIV (PLWH) and remains a challenge to HIV prevention, treatment, and care. Research has overwhelmingly focused on individual cognitive measures of HIV stigma (e.g., internalized, anticipated, and experienced). However, little research explores the interactions and societal structures through which HIV stigma is produced. Data from qualitative interviews with 30 black gay and bisexual men living with HIV in the U.S. Deep South revealed an interconnected and interdependent set of processes that produce and reproduce HIV stigma. These included social interactions (silence, euphemism, and gossip), witnessed acts of marginalization, word-of-mouth transmission of HIV misinformation, and laws and policies carried out within the education and criminal justice systems. Efforts to reduce stigma that focus on individual beliefs and attitudes are critical to improving the well-being of PLWH. However, reducing HIV stigma requires intervening on the social interactions and structures through which HIV stigma is produced and reproduced.

Examining Associations Between Resilience and PrEP Use Among HIV-negative GBM in Toronto, Montreal and Vancouver

This study evaluated the association between resilience and PrEP use among a population-based sample of Canadian gay, bisexual, and other men who have sex with men (GBM). Sexually active GBM aged ≥ 16 years old were recruited via respondent-driven sampling (RDS) in Toronto, Montreal, and Vancouver from 02/2017 to 07/2019. We conducted a pooled cross-sectional analysis of HIV-negative/unknown GBM who met clinical eligibility for PrEP. We performed multivariable RDS-II-weighted logistic regression to assess the association between scores on the Connor-Davidson Resilience-2 Scale and PrEP. Mediation analyses with weighted logistic and linear regression were used to assess whether the relationship between minority stressors and PrEP use was mediated by resilience. Of 1167 PrEP-eligible GBM, 317 (27%) indicated they took PrEP in the past six months. Our multivariable model found higher resilience scores were associated with greater odds of PrEP use in the past six months (aOR = 1.13, 95%CI = 1.00, 1.28). We found that resilience reduced the effect of the association between heterosexist discrimination and PrEP use. Resilience also mediated the relationship between internalized homonegativity and PrEP use and mediated the effect of the association between LGBI acceptance concern and PrEP use. Overall, PrEP-eligible GBM with higher resilience scores had a greater odds of PrEP use in the past six months. We also found mixed results for the mediating role of resilience between minority stress and PrEP use. These findings underline the continued importance of strength-based factors in HIV prevention.

Sex Conservatism, Internalized Homonegativity, PrEP Stigma, and Intention to Use PrEP: A Study of Chinese-Speaking Gay and Bisexual Male Youth in Hong Kong

Pre-exposure prophylaxis (PrEP) stigma has been found to be a major barrier to PrEP acceptability and uptake. Research has found that different ethnic/cultural groups display varying levels of PrEP stigma. This article studies sex conservatism and internalized homonegativity as two sexuality- and culture-related aspects that influence PrEP stigma and intention to use PrEP. An online survey of 279 young gay and bisexual men in Hong Kong found that internalized homonegativity was positively associated with PrEP stigma. Respondents who were more conservative about sex showed lower intention to use PrEP, whereas those who had higher income and more positive attitudes about PrEP were more likely to express intention to use PrEP. This study provides novel empirical evidence for understanding PrEP stigma and uptake from a sexuality and cultural perspective. The influence of sexuality- and culture-related factors on PrEP stigma and uptake warrants greater attention, especially in the Asia-Pacific region.

Pre-Exposure Prophylaxis (PrEP) Dissemination: Adapting Diffusion Theory to Examine PrEP Adoption

PrEP adoption among African-American men-who-have-sex-with-men (AAMSM) remains low. We applied Diffusion-of-Innovations (DOI) theory to understand PrEP adoption processes among young HIV-negative/status unknown AAMSM (AAYMSM; N = 181; 17-24 years). Quantitative and qualitative analyses were used to examine predictors of PrEP diffusion stages. Most AAYMSM were in the persuasion stage (PrEP-aware, hadn't adopted; 72.4%). Our results suggest that model antecedents are DOI stage-specific. PrEP awareness (knowledge stage) was associated with lower levels of social stigma (p < .03) and greater health literacy (p < .05), while sexual risk (p < .03) and education (p < .03) predicted PrEP adoption (12.2%). PrEP efficacy and side effects were primary innovation characteristics influencing adoption receptivity in the persuasion stage. Interventions to improve PrEP diffusion should be tailored to stage-specific antecedents depending on how a community is stratified across the DOI stages.

Oral HIV Self-Implemented Testing: Performance Fidelity Among African American MSM

Oral-Self Implemented HIV Testing (Oral-SIT) offers a low-cost way to extend the reach of HIV testing systems. It is unclear, however, if high risk populations are able to perform the test with high fidelity. Using a simulation-based research design, we administered desensitized Oral-SIT kits to African American MSM (AAMSM; 17-24 years, N = 178). Participants were HIV negative or never tested, and had never self-administered an Oral-SIT kit. We assessed performance fidelity, and hypothesized antecedents. High levels of social stigma were associated with lower levels of training knowledge (Range = No Errors: 51.9%, 4 Errors: 0.6%) and performance fidelity (Range = No Errors: 39.9%, 3 Errors: 1.7%). Training knowledge and prior testing history were positively associated with performance fidelity. The present work extends research on HIV-related social stigma and suggests that social stigma inhibits knowledge acquisition and task performance. The Oral-SIT training materials were understood by individuals with a wide-range of educational backgrounds. Interventions are needed, however, to further improve Oral-SIT performance fidelity.

Stigma and Mobile App Use Among Young Black Men Who Have Sex With Men

Young black men who have sex with men (YBMSM) are disproportionately affected by HIV. Intersectional stigmas are associated with increased HIV vulnerability, and worse outcomes for YBMSM with HIV. YBMSM find sex partners through sexual networking apps, but stigma on apps has been poorly studied. We conducted cross-sectional analysis of 324 YBMSM seeking sex partners through apps to assess stigma experiences in eight dimensions compared to non-users (N = 150). We conducted detailed stratified analyses to identify granular stigma data. App users had higher median scores than non-users in perceived HIV discrimination, perceived HIV stigma, experienced sexual minority stigma, racial discrimination, and perceived homophobia. We demonstrate higher levels of intersectional stigmas among app users than non-users, but did not find an overall increase in stigma with increasing app use. Considering the prominent role of apps in YBMSM sexual networking, interventions that reduce stigma on apps are needed.

Prevalence and Correlates of PrEP Awareness and Use Among Black Men Who Have Sex with Men and Women (MSMW) in the United States

Men who have sex with men and women (MSMW), including those who are Black, experience HIV-related disparities compared to men who have sex with men only (MSMO). Few studies have assessed the prevalence and correlates of pre-exposure prophylaxis (PrEP) awareness and use among Black MSMW. We recruited MSM ≥ 18 attending Black Gay Pride events between 2014-2017. We conducted multivariable logistic regressions to assess differences in PrEP awareness and use among HIV-negative Black MSM (n = 2398) and within Black MSMW (n = 419). MSMW were less likely than MSMO to report PrEP awareness (p < 0.001). Among PrEP-aware MSM, MSMW were more likely than MSMO to report PrEP use (p < 0.05). MSMW receiving gay community support were more likely to be PrEP-aware (p < 0.01). MSMW reporting any past-year STI diagnoses were more likely to report PrEP use (p < 0.01). Findings suggest that PrEP awareness campaigns tailored for Black MSMW, concomitant with STI-to-PrEP interventions, will facilitate greater PrEP uptake in this population.

Interaction Patterns of Men Who Have Sex With Men on a Geosocial Networking Mobile App in Seven United States Metropolitan Areas: Observational Study

BACKGROUND

The structure of the sexual networks and partnership characteristics of young black men who have sex with men (MSM) may be contributing to their high risk of contracting HIV in the United States. Assortative mixing, which refers to the tendency of individuals to have partners from one's own group, has been proposed as a potential explanation for disparities.

OBJECTIVE

The objective of this study was to identify the age- and race-related search patterns of users of a diverse geosocial networking mobile app in seven metropolitan areas in the United States to understand the disparities in sexually transmitted infection and HIV risk in MSM communities.

METHODS

Data were collected on user behavior between November 2015 and May 2016. Data pertaining to behavior on the app were collected for men who had searched for partners with at least one search parameter narrowed from defaults or used the app to send at least one private chat message and used the app at least once during the study period. Newman assortativity coefficient (R) was calculated from the study data to understand assortativity patterns of men by race. Pearson correlation coefficient was used to assess assortativity patterns by age. Heat maps were used to visualize the relationship between searcher's and candidate's characteristics by age band, race, or age band and race.

RESULTS

From November 2015 through May 2016, there were 2,989,737 searches in all seven metropolitan areas among 122,417 searchers. Assortativity by age was important for looking at the profiles of candidates with correlation coefficients ranging from 0.284 (Birmingham) to 0.523 (San Francisco). Men tended to look at the profiles of candidates that matched their race in a highly assortative manner with R ranging from 0.310 (Birmingham) to 0.566 (Los Angeles). For the initiation of chats, race appeared to be slightly assortative for some groups with R ranging from 0.023 (Birmingham) to 0.305 (Los Angeles). Asian searchers were most assortative in initiating chats with Asian candidates in Boston, Los Angeles, New York, and San Francisco. In Birmingham and Tampa, searchers from all races tended to initiate chats with black candidates.

CONCLUSIONS

Our results indicate that the age preferences of MSM are relatively consistent across cities, that is, younger MSM are more likely to be chatted with and have their profiles viewed compared with older MSM, but the patterns of racial mixing are more variable. Although some generalizations can be made regarding Web-based behaviors across all cities, city-specific usage patterns and trends should be analyzed to create targeted and localized interventions that may make the most difference in the lives of MSM in these areas.

Pre-exposure Prophylaxis (PrEP) Awareness and Use Within High HIV Transmission Networks

Improved implementation of pre-exposure prophylaxis (PrEP) should be a valuable tool within communities experiencing high HIV incidence, such as black men who have sex with men (MSM). Using baseline data from the Chicago arm of the Transmission Reduction Intervention Project (TRIP), we examined awareness and use of PrEP within HIV potential transmission networks. Transmission Reduction Intervention Project recruited participants ages 18-69 (N = 218) during 2014-2016 from networks originating from recently and chronically HIV-infected MSM and transgender persons. In total, 53.2% of participants had heard of PrEP, while 8 (6.5%) HIV-negative participants reported ever using PrEP. In multivariable regression, PrEP awareness was associated with identifying as gay, attending some college or higher, having an HIV test in the previous 6 months, and experiencing HIV-related social support. PrEP awareness was not associated with experiencing or observing HIV-related stigma. PrEP use was associated with participants knowing two or more other PrEP-users. These findings demonstrate moderate awareness, but low uptake of PrEP within HIV potential transmission networks in Chicago. Future research should explore how to increase PrEP use in these networks and investigate the social dynamics behind our finding that PrEP users are more likely to know other PrEP users.
