Dyadic dynamics of HIV risk among transgender women and their primary male sexual partners: the role of sexual agreement types and motivations

HIV incidence and mortality in transgender women in the eastern and southern USA: a multisite cohort study

BACKGROUND

Epidemiological monitoring of HIV among transgender women is minimal despite prioritisation of this group in the US National HIV/AIDS Strategy (2022-2025). We aimed to estimate HIV incidence in a multisite cohort of transgender women in the eastern and southern USA. Participant deaths were identified during follow-up; thus, we felt it was an ethical imperative to report mortality alongside HIV incidence.

METHODS

In this study, we established a multisite cohort across two modes: a site-based, technology-enhanced mode in six cities (Atlanta, Baltimore, Boston, Miami, New York City, and Washington, DC) and an exclusively digital mode that spanned 72 eastern and southern US cities that matched the six site-based cities based on population size and demographics. Trans feminine adults (≥18 years) who were not living with HIV were eligible and followed up for at least 24 months. Participants completed surveys and oral fluid HIV testing with clinical confirmation. We ascertained deaths through community and clinical sources. We estimated HIV incidence and mortality using the number of HIV seroconversions and deaths, respectively, divided by person-years accumulated from enrolment. Logistic regression models were used to identify predictors of HIV seroconversion (primary outcome) or death.

FINDINGS

Between March 22, 2018, and Aug 31, 2020, we enrolled 1312 participants with 734 (56%) in site-based and 578 (44%) in digital modes. At the 24-month assessment, 633 (59%) of 1076 eligible participants consented to extending participation. 1084 (83%) of 1312 participants were retained at this analysis based on the study definition of loss to follow-up. As of May 25, 2022, the cohort participants had contributed 2730 accumulated person-years to the analytical dataset. Overall HIV incidence was 5·5 (95% CI 2·7-8·3) per 1000 person-years and incidence was higher among Black participants and those living in the south. Nine participants died during the study. The overall mortality rate was 3·3 (95% CI 1·5-6·3) per 1000 person-years, and the rate was higher among Latinx participants. Identical predictors of HIV seroconversion and death included residence in southern cities, sexual partnerships with cisgender men, and use of stimulants. Participation in the digital cohort and seeking care for gender transition were inversely associated with both outcomes.

INTERPRETATION

As HIV research and interventions are increasingly delivered online, differences by mode highlight the need for continued community and location-based efforts to reach the most marginalised transgender women. Our findings underscore community calls for interventions that address social and structural contexts that affect survival and other health concerns alongside HIV prevention.

A cluster randomized trial to reduce HIV risk from outside partnerships in Zambian HIV-Negative couples using a novel behavioral intervention, "Strengthening Our Vows": Study protocol and baseline data

BACKGROUND

Heterosexual couples contribute to most new HIV infections in areas of generalized HIV epidemics in sub-Saharan Africa. After Couples' Voluntary HIV Counseling and Testing (CVCT), heterosexual concordant HIV negative couples (CNC) in cohabiting unions contribute to approximately 47% of residual new infections in couples. These infections are attributed to concurrent sexual partners, a key driver of the HIV epidemic in Zambia.

METHODS/DESIGN

Ten Zambian government clinics in two of the largest cities were randomized in matched pairs to a Strengthening Our Vows (SOV) intervention or a Good Health Package (GHP) comparison arm. SOV addressed preventing HIV infection from concurrent partners and protecting spouses after exposures outside the relationship. GHP focused on handwashing; water chlorination; household deworming; and screening for hypertension, diabetes and schistosomiasis. CNC were referred from CVCT services in government clinics. Follow-up includes post-intervention questionnaires and outcome assessments through 60 months. Longitudinal outcomes of interest include self-report and laboratory markers of condomless sex with outside partners and reported sexual agreements. We present baseline characteristics and factors associated with study arm and reported risk using descriptive statistics.

RESULTS

The mean age of men was 32 and 26 for women. On average, couples cohabited for 6 years and had 2 children. Baseline analyses demonstrated some failures of randomization by study arm which will be considered in future primary analyses of longitudinal data. An HIV/STI risk factor composite was not different in the two study arms. Almost one-quarter of couples had an HIV risk factor at baseline.

DISCUSSION

In preparation for future biomedical and behavioral interventions in sub-Saharan Africa, it is critical to understand and decrease HIV risk within CNC.

Heterosexual Cisgender Men Partnered with Transgender Women Exhibit Higher HIV/STI Sexual Risk than Their Gay, Bisexual, and Queer Counterparts: Findings from a U.S.-Based Convenience Sample Recruited Online

Cisgender men are frequently vectors for HIV transmission among transgender women. Despite this, the correlates of sexual risk among these men remain under-examined. The purpose of the present study was to explore potential differences in relationship characteristics, sexual risk-taking, and risk-reduction strategies among cisgender men partnered with transgender women. The study utilized secondary screening data provided by adult cis men who reported being in a primary relationship with a trans woman (N = 710). Gay men (18%) were comparatively older, and most likely to report both HIV seropositivity and committed pairings. Heterosexual men (14%) were more likely to report exchange sex, briefer relationships, extra-dyadic sex, lesser serostatus awareness or PrEP uptake. Queer men (7%) were youngest, and most likely to access PrEP. Heterosexual cis men with trans women partners may be subject to unique socio-cultural drivers of sexual risk, such as heteronormative pressures and relationship stigma.

Exploring discrepant knowledge of partner sexual behaviour to inform self-risk assessment in a high HIV burdened district in rural KwaZulu-Natal

Understanding the sexual relationships of young women is critical for preventing HIV infections. This study aimed to describe the sexual behaviour of partners, comparing the accuracy of sexual health knowledge between partners. The study took place in 2017 in KwaZulu-Natal, South Africa. Purposive sampling was used to select 18-27-year-old sexually active women. Consenting female participants completed a structured and semi-structured interview, while consenting male sexual partners identified through the female participant completed a structured questionnaire on sexual health information. Using a reflexive inductive approach and thematic analysis, we identified key discrepancies in the assumptions partners make about each other's sexual health information. Twenty-three sexual dyads were identified and four key discrepancies were identified: Age: partners either over or underestimated the age of their partners, HIV status: where partners were unaware of, or incorrectly assumed their partner's status, Lack of awareness of partner's concurrent relationships and more general knowledge of the partner's sexual health behaviours. Discussions about sexual health are mediated by relationship length, type of partner, power and perceived fidelity. While it is possible to undertake dyadic level research, ethical tensions remain. Sex-positive and egalitarian sexual health interventions that target the individual, as well as the sexual relationship, are needed.

Global scoping review of HIV prevention research with transgender people: Transcending from trans-subsumed to trans-centred research

INTRODUCTION

Globally, transgender populations are disproportionally impacted by HIV and effective HIV prevention interventions targeting these populations are critically needed. Such interventions require research focused on the specific needs and experiences of transgender people. This methodological review aims to determine the extent to which HIV prevention research has included transgender participants by subsuming them into non-transgender populations, or by centring them either in comparison with other groups or as the sole focus of research.

METHODS

We searched five electronic databases (e.g. SCOPUS) for empirical studies that focused on HIV prevention and included transgender participants, published through 31 December 2020. For each study, we extracted information on: (a) types of inclusion of transgender participants; (b) total sample size and number/percentage of transgender participants; (c) country(ies) where study was conducted; (d) HIV research topics; (e) methods (i.e. quantitative, qualitative or mixed-methods research) and (f) gender identity of transgender participants.

RESULTS AND DISCUSSION

Of 667 HIV prevention studies included in the review, 38.5% subsumed transgender participants into cisgender populations (most frequently combining transgender women with cisgender men who have sex with men), 20.4% compared transgender and cisgender participants and 41.1% focused exclusively on transgender populations. Our global scoping review also revealed that these three types of transgender inclusion in HIV prevention research vary greatly over time, place and thematic areas. Transgender women are the focus of the majority of reviewed studies, whereas transgender men and gender expansive people are rarely included as participants.

CONCLUSIONS

Inclusion of transgender persons as participants in HIV prevention research has significantly increased, particularly in the last decade. Further research centred on transgender participants and their experiences are needed to develop effective HIV prevention interventions for transgender populations. We advocate for HIV prevention research to move from subsuming transgender people, to trans-centred research that asks questions that focus on their specific needs and experiences. We provide recommendations to move from trans-subsumed to trans-centred HIV prevention research.

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.

HIV Prevention Among Cisgender Men Who have Sex with Transgender Women

Cisgender men who have sex with transgender women face elevated risk for HIV, yet are understudied in prevention research. We conducted in-depth interviews with 19 men who have sex with transgender women in Baltimore, Maryland and Atlanta, Georgia to explore perspectives on HIV prevention. Participants used several strategies to reduce HIV risk: condoms, frequent HIV testing, communication about HIV status with partners, and limiting the types of sex acts performed. While condom use was inconsistent, it was preferred over pre-exposure prophylaxis, in part due to medical distrust. HIV self-testing was generally viewed unfavorably. Although most participants were referred to the study by their transgender women partners, they recommended reaching other men who have sex with transgender women in bars, nightclubs, online, and through social media. HIV prevention interventions should be inclusive of the needs and experiences of men who have sex with transgender women.

Couples-based approach to HIV prevention for transgender women and their partners: study protocol for a randomised controlled trial testing the efficacy of the 'It Takes Two' intervention

INTRODUCTION

HIV transmission and acquisition risk among transgender women is particularly high in the context of primary partnerships. This project extends a previous pilot couples-focused HIV intervention programme, which was shown to be feasible, acceptable and promising in reducing sexual risk behaviour among transgender women and their partners. This randomised controlled trial (RCT) tests the efficacy of this culturally sensitive HIV prevention programme for HIV-serodiscordant and HIV-negative seroconcordant transgender women and their partners.

METHODS AND ANALYSIS

To finalise the protocol for trial, we used qualitative methods to hone eligibility criteria, refine the intervention and control manuals, and name and brand the intervention ('It Takes Two'). The RCT investigates the effects of the It Takes Two intervention on Composite Risk for HIV (CR-HIV) among 100 couples. CR-HIV is a binary indicator of couple HIV risk using validated measures of sexual behaviour, pre-exposure prophylaxis use among HIV-negative participants and viral suppression among participants living with HIV. Using a two-arm RCT, we will examine intervention effects on CR-HIV at 12-month follow-up comparing transgender women and their partners randomised to the intervention versus control (HIV prevention information only).

ETHICS AND DISSEMINATION

This study has been reviewed and approved by the University of California, San Francisco (19-28624) and the University of Michigan (HUM00147690) Institutional Review Boards. Participants provide informed consent before taking part of the study activities. Results will be published in peer-reviewed journals and presented at scientific conferences. We will make our results available to the community of researchers and general public interested in transgender health to avoid unintentional duplication of research, as well as to others in the health and social services community, including LGBT community-based organisations, AIDS service organisations and other transgender-serving organisations. The full de-identified dataset and codebook will be shared at the University of Michigan Digital Repository.

Strategies for engaging transgender populations in HIV prevention and care

PURPOSE OF REVIEW

Transgender (trans) populations are heavily impacted by HIV, yet face structural, social, and individual barriers to engagement in HIV prevention and care. In this review, we summarize the data on barriers and facilitators and discuss evidence-informed strategies to facilitate access to and engagement in HIV prevention and care by trans communities.

RECENT FINDINGS

Intersectional stigma and discrimination at structural, community, individual levels present substantial impediments to HIV prevention and optimal care. Access to gender-affirming health care is a priority for trans communities. Where trans communities are highly networked, these networks may provide a strong infrastructure for disseminating HIV innovations and reaching individuals who are not engaged in HIV services. Efforts to engage trans people in HIV prevention and care must address stigma, provide gender-affirming services, and build on community strengths and priorities to ensure trans populations achieve maximum benefit from advances in HIV prevention and care.

SUMMARY

Combination approaches that respond to the complex drivers of HIV in trans communities represent promising strategies for engaging trans people and their partners in HIV prevention and care.

Characterizing Men Who Have Sex with Transgender Women in Lima, Peru: Sexual Behavior and Partnership Profiles

HIV prevalence is high among transgender women (TW), but how HIV is transmitted to this population is not well understood. This analysis aims to characterize sexual partners of TW (PTW) to understand how their behavior contributes to HIV risk among TW. We examined baseline data from TW, PTW, and men who have sex with men (MSM) from a treatment-as-prevention study in Lima, Peru. Individual and partnership characteristics were compared across groups, and Poisson regression was used to calculate prevalence ratios for associations between sexual concurrency and potential correlates. We found that 81% of PTW had no cisgender male partners. Prevalence of alcohol dependency, concurrency, and condomless anal intercourse was high and HIV testing was low compared to the other groups. Our results suggest that PTW are a distinct population from MSM and TW, engage in behavior associated with HIV transmission, and are likely not well reached by HIV prevention interventions.

Differences Between Groups of Pre-exposure Prophylaxis (PrEP) Using Couples in HIV-Negative/Unknown Relationships

BACKGROUND

Epidemiology research is limited on the characteristics of HIV pre-exposure prophylaxis (PrEP) using couples.

SETTING

US nationwide sample recruited online in 2017.

METHODS

HIV negative/unknown gay, bisexual, and other men who have sex with men with HIV negative/unknown partners (n = 3140) were asked about individual and main partner PrEP uptake. Men were coded into the following 5 groups: (1) neither participant nor partner on PrEP, (2) partner only on PrEP, (3) participant only on PrEP, (4) both on PrEP, and (5) unknown partner PrEP use. We examined associations of demographics, relationship factors, condomless anal sex (CAS) with main and causal partners, bacterial sexually transmitted infection diagnoses, and sexual positioning with reported dyadic PrEP use using fully adjusted multinomial logistic regressions.

RESULTS

PrEP use was 3.2% for the partner only, 5.7% for the participant only, and 4.9% for both the participant and partner; 5.6% reported not knowing their partner's PrEP use status. Men who reported any CAS with their main partner or any CAS with male casual partners were both more likely to be classified in the dyadic PrEP use group compared with the neither on PrEP group. Compared with monogamous, men in open arrangements were more likely to be classified in each of the 3 PrEP groups compared with the neither on PrEP group. Six-month bacterial sexually transmitted infection prevalence was 2.8%, 8.1%, 8.3%, 15.6%, and 4.0% for the 5 groups, respectively.

CONCLUSIONS

PrEP use occurred during times of higher risk behavior engagement, but further efforts are needed to expand PrEP use to more partnered gay, bisexual, and other men who have sex with men.

Understanding HIV risk and vulnerability among cisgender men with transgender partners

In the HIV pandemic, cisgender (ie, non-transgender) men with transgender partners are an underserved population. Complexities of sexuality and gender affect HIV vulnerability for this group, including not identifying with conventional sexual orientation categories (eg, bisexual, heterosexual, or gay) and having attractions based on gender role or expression rather than genital anatomy. Only one HIV prevention interventional study in this population was identified, and one study that assessed the perceived acceptability of an intervention. We found no data for interventions using pre-exposure prophylaxis, interventions for cisgender men with transgender men partners, or cisgender men with casual or transactional sexual partnerships with transgender people. Cisgender men with transgender partners are not easily categorised using traditional HIV risk categories. Additional research is needed to understand stigma and other structural drivers of HIV vulnerability, sexual networks and practices, substance use patterns, and biomedical prevention interest and uptake for this group. Studies that use an intersectional lens and syndemic framework could offer key insights.

Relationship Stigma and HIV Risk Behavior Among Cisgender Men Partnered with Transgender Women: The Moderating Role of Sexual Identity

Cisgender men partnered with transgender women are an understudied and hard to engage population in HIV prevention efforts. Relationship stigma-the anticipation of negative treatment based on having a relationship with a member of a stigmatized group-has been linked to adverse health behaviors, but it remains unclear whether different sources of relationship stigma (i.e., family, friends, and the general public) are associated with HIV risk behaviors and whether these associations may vary by men's sexual identities (e.g., gay, bisexual, and heterosexual). The current study examined associations between relationship stigma and HIV risk behaviors and whether these associations were moderated by sexual identity. We recruited a convenience sample of 185 cisgender men in primary partnerships with transgender women to participate in a one-time survey. Gay identified men reported greater levels of relationship stigma from the general public compared with heterosexually identified men. In multivariable models, higher levels of relationship stigma from the public were associated with increased odds of engaging in drug use prior to having condomless sex and receiving an STI diagnosis in the last 30 days. There were significant interaction effects such that higher levels of relationship stigma from the public were associated with both indicators of HIV risk for gay identified men but not for heterosexually identified men. Findings support the importance of HIV prevention approaches accounting for relationship stigma from the general public and the diverse sexual identities of men partnered with transgender women when seeking to increase linkage to and engagement in HIV prevention services, including biomedical prevention strategies.

The HIV-Related Risk Factors of the Cisgender Male Sexual Partners of Transgender Women (MSTW) in the United States: A Systematic Review of the Literature

Cisgender male sexual partners of transgender women (MSTW) may be at risk for HIV infection. We performed a review of HIV risk factors among MSTW. We searched PubMed database for empirical quantitative U.S.-based studies that included MSTW and were published in English up to November 2018. Of the 4,680 total papers identified, 6 unique studies were included. MSTW displayed heterogeneity in HIV risk factors (e.g., condom use, sexual partners, sexual positions, substance use). In our exploratory meta-analyses, estimated prevalence of self-reported HIV positive status among MSTW was 30.6%, HIV unknown status was 8.8%, and self-reported condomless anal sex with transgender women was 46.1%. Reports of sexual health communication with transgender women was low. More research on MSTW populations is needed to better understand this population's unique needs in the context of recent advancements in HIV prevention.

Commitment, interpersonal stigma, and mental health in romantic relationships between transgender women and cisgender male partners

The goals of this study were to: (a) examine associations between interpersonal stigma and psychological distress among a sample of transgender women and their cisgender male partners; and (b) identify whether commitment moderates the association between interpersonal stigma and psychological distress. To address these aims, 191 couples consisting of transgender women and their cisgender male partners completed a one-time survey. Actor-partner interdependence models (APIM) were fit to examine stigma, commitment, and their interaction on psychological distress. More frequent experiences of interpersonal stigma were associated with elevated psychological distress for both partners. For transgender women, higher commitment was associated with lower psychological distress. There was a significant interaction effect such that the association between interpersonal stigma and psychological distress was attenuated by greater commitment for transgender women, but not for their cisgender male partners. Findings provide preliminary support for associations between interpersonal stigma and mental health of both partners, and identify commitment as a potential stress buffer for transgender women.

Optimizing HIV prevention and care for transgender adults

: Transgender women have recently been acknowledged as a unique and important risk group in HIV research and care. Although transgender men also face specific problems related to HIV infection, less is known about the risk behaviours and HIV prevalence of this important population. This article highlights key issues relating to the epidemiology, prevention, treatment and management of complications of HIV infection in transgender adults living with HIV, and explores future areas for HIV-related research, with the ultimate goal of improving healthcare provision and quality of life for transgender persons worldwide.

"Unspoken Agreements": Perceived Acceptability of Couples HIV Testing and Counseling (CHTC) Among Cisgender Men with Transgender Women Partners

Transgender women (TW) are one of the highest risk groups for HIV infection globally; however, the HIV testing needs of their cisgender (non-transgender) male partners remain largely unknown. This study sought to examine the perceived acceptability of couples HIV testing and counseling (CHTC) for TW-male dyads from the perspective of cisgender men who partner with TW. Between September 2016 and June 2017, 19 cisgender men (mean age = 40.1, SD = 12.8) who currently have, or have ever had a TW partner completed an in-depth semi-structured phone interview and brief survey to gather data on acceptability of CHTC, as well as perceived barriers and facilitators to CHTC for TW-male couples. Qualitative data were thematically analyzed and integrated with survey data. Acceptability of CHTC was high in the sample (89.5%) but was complex and largely contingent on: (1) monogamy and commitment as critical precursors to CHTC acceptability; (2) risk perception and level of comfort with CHTC; (3) understandings of sexual agreements; and (4) personal relationships versus other TW-male relationships. Findings have implications for culturally-adapting and implementing CHTC in real-world settings for TW-male couples, as well as for meeting the individual HIV testing needs of cisgender men who partner with TW.

Sexual Agreements: A Scoping Review of Measurement, Prevalence and Links to Health Outcomes

A sexual agreement is a mutual understanding between two partners regarding sexual and relational behaviors both within and outside of their relationship. Sexual agreements have been central to research and programming efforts around HIV prevention, primarily for male couples. A comprehensive scoping review of the primary literature on sexual agreements, including negotiated safety, was performed to identify what is known about sexual agreements among couples (n = 66). Results indicate a wide range of prevalence of agreements and measurements used to characterize sexual agreements. Findings also report associations between sexual agreements and health and relational outcomes. Several knowledge gaps were identified; specifically, the need to expand sexual agreements research beyond MSM populations and the need to better understand agreement breaks, break disclosure, and how variation in agreement categorization may impact reported prevalence. This review demonstrates the importance of broadening the evidence-base of sexual agreements research and programmatic focus.

Managing the risk of intimacy: accounts of disclosure and responsiveness among people with HIV and intimate partners of people with HIV

It is well known that concerns about sexual risk tend to decline among people in intimate relationships where there is established commitment and trust. In the context of relationships at increased risk for HIV transmission, interactions involving disclosure and partner responsiveness are key to maintaining intimacy and physical safety. This paper explores concepts of risk and sexual intimacy articulated by a community sample of 30 people living with HIV and their intimate relationship partners. Data revealed the shifts in intimate relationship dynamics upon the disclosure of an HIV diagnosis, the importance of intimacy in the context of managing one or both partners' HIV care and responses to new advances in HIV prophylaxis. Findings suggest that participants' experiences of self-disclosure and partner responsiveness most often resulted in an increased sense of protectiveness from and for partners. This suggests that health-promoting messaging should be adapted to be more relevant to intimate couple communication and mutual support.

HIV Prevention Among Transgender Populations: Knowledge Gaps and Evidence for Action

PURPOSE OF REVIEW

The purpose of this review is to summarize the available evidence-based HIV prevention interventions tailored for transgender people.

RECENT FINDINGS

A limited number of evidence-based HIV prevention interventions have been tested with transgender populations. Most existing interventions target behavior change among transgender women, with only one HIV prevention program evaluated for transgender men. Studies addressing biomedical interventions for transgender women are ongoing. Few interventions address social and structural barriers to HIV prevention, such as stigma, discrimination, and poverty. Evidence-based multi-level interventions that address the structural, biomedical, and behavioral risks for HIV among transgender populations, including transgender men, are needed to address disparities in HIV prevalence. Future research should address not only pre-exposure prophylaxis uptake and condom use but also structural barriers that limit access to these prevention strategies.

Couples-Focused Prevention Program to Reduce HIV Risk Among Transgender Women and Their Primary Male Partners: Feasibility and Promise of the Couples HIV Intervention Program

HIV risk among transgender women has been attributed to condomless sex with primary male partners. This study pilot tested a couples-focused HIV intervention program for transgender women and their primary male partners. We analyzed data from 56 transgender women and their male partners (n = 112 participants) who were randomized as a couple to one of two groups. Participants in the intervention group (27 couples) received 3 counseling sessions: 2 couples-focused sessions, which discussed relationship dynamics, communication, and HIV risk, and 1 individual-focused session on HIV prevention concerns. Participants in the control group (29 couples) received 1 session on general HIV prevention information delivered to both partners together. At 3-month follow-up, participants in the intervention reported lower odds of condomless sex with primary partners (OR 0.5, 95 % CI 0.3-1.0), reduced odds of engaging in sex with a casual partner (OR 0.3, 95 % CI 0.1-1.0), and reduction in the number of casual partners (B = -1.45, SE = 0.4) compared with the control group. Findings provide support for the feasibility and promise of a couples-focused HIV prevention intervention for transgender women and their primary male partners.

Psychometric evaluation of the Condom Barriers and Motivations Scale (CBMS)

The Condom Barriers and Motivations Scale (CBMS) was developed to measure four distinct categories of barriers and motives to condom use, including: risk reduction motivations, pleasure reduction barriers, intimacy interference barriers, and partner pressure barriers. The CBMS is a 16-item scale with four items that correspond to each of these subscales. The CBMS was tested in two samples of gay and bisexual men. Results support the reliability and validity of the scale and its structure. Results also indicate that CBMS subscales are distinct from general measures of sexual wellbeing, personality factors, or relationship quality (i.e., discriminant validity) and are associated with self-reported condom use with different partner types (i.e., construct validity). The CBMS can be helpful in better understanding the dynamics of condom use in the context of pre-exposure prophylaxis decision-making, and can shed light on innovative approaches to enhance condom use as part of comprehensive HIV prevention and sexual health goals.

Gender Affirmation and Resiliency Among Black Transgender Women With and Without HIV Infection

Purpose: Among black transgender women (transwomen) at high risk of HIV acquisition or already living with HIV/AIDS, the study examined whether medical or socially based gender affirming factors may contribute differentially to selected measures of resiliency, perceived stress, and a scale measure of mental health outcomes. This question has implications for clinical care and counseling of this population.

Methods: Seventy-seven black transwomen were recruited to participate in a private, face-to-face structured interview. Two index measures of gender affirmation (GA) were constructed from the data. One comprised medical aspects only and the other comprised social aspects of GA. Assessed outcomes were personal competence and acceptance of self and life (resiliency), perceived stress and recent anxiety, depression, and suicide ideation (mental health). Associations between GA variables and outcomes were first assessed using bivariate level correlations. Significant bivariate associations were then tested in multivariable regression models adjusting for age and HIV status.

Results: Mean age of the sample was 34.5 years. More than one-half of the sample (62.3%) indicated being HIV-infected. None of the bivariate or multivariable associations pertaining to GA medical factors were significant. Conversely, the social GA factors were significant and protective with all four outcomes. In the presence of age and HIV status, greater social GA was significantly associated with greater personal competence, acceptance of self and life, and positive mental health outcome. HIV status had an independent effect on personal competence, acceptance of self and life, with HIV-positive transwomen scoring higher on both measures.

Conclusion: Among black transwomen at high risk of HIV acquisition or already HIV-infected, study findings suggest the possibility that socially based GA may play a prominent role in strengthening the resiliency and mental health of black transwomen. This same protective effect may not occur as a consequence of gender affirming body modification practices.

The conflation of gender and sex: Gaps and opportunities in HIV data among transgender women and MSM

Historically, HIV studies have conflated men who have sex with men (MSM) with transgender (trans) women, explicitly excluded trans individuals, or included sample sizes of trans people that are too small to reach meaningful conclusions. Despite the heavy burden of HIV among trans women, conflation of this population with MSM has limited the information available on the social and behavioural factors that increase HIV vulnerability among trans women and how these factors may differ from MSM. Using data sets from quantitative studies among MSM (n = 645) and trans women (n = 89), as well as qualitative in-depth interviews with 30 trans women in Baltimore, we explore what these data tell us about similarities and differences in HIV vulnerability between the two groups and where they leave gaps in our understanding. We conclude with implications for data collection and intervention development.

This same protective effect may not occur as a consequence of gender affirming body modification practices.
