Abstract

This study assessed disparities in pre-exposure prophylaxis (PrEP) use among transgender and gender expansive youth and young adults (N = 477) between 15 and 24 years old in the CARES (ATN 149) and TechStep (ATN 160) study protocols within the National Adolescent Medicine Trials Network for HIV/AIDS Interventions (ATN). Structural equation modeling was used to test mediation pathways between gender identity and PrEP uptake among the full sample and stratified by sex assigned at birth. Lifetime PrEP uptake was higher among those assigned male at birth (26%) versus assigned female at birth (9%), explained by greater structural and behavioral risks and perceived need for PrEP, especially among trans women. Among those assigned female at birth, PrEP uptake was higher among trans men (12%) than nonbinary participants (6%). Our findings characterize key structural and behavioral drivers of PrEP use and highlight the need to reduce barriers to healthcare for trans youth, particularly in the South.

Abstract

Black and Latinx transgender women in the United States (U.S.) are at disproportionately high risk for HIV. Although HIV pre-exposure prophylaxis (PrEP) reduces the risk of HIV infection, uptake and persistence (i.e., ability to continue taking PrEP over time) can be a challenge for Black and Latinx transgender women due to myriad social and structural forces. In this qualitative study, we present unique data on the facilitators of PrEP persistence from Black and Latinx transgender women who initiated PrEP and exhibited varying levels of persistence during a demonstration project in Southern California. PrEP persistence was assessed by collecting quantitative intracellular tenofovir-diphosphate (TFV-DP) levels on dried blood spot (DBS) samples collected at weeks 12 and 48. Informed by the socioecological framework, we conducted and analyzed interviews using qualitative content analysis to determine themes on the facilitators of PrEP persistence. Individual-level facilitators included the use of reminders, having high individual-level HIV risk perception, feeling empowered to take PrEP, and reporting having improved peace of mind and mental health because of taking PrEP. Interpersonal/Community-level facilitators included feeling motivation to prevent HIV in the community, motivation to prevent HIV in the context of sex work, and having high community-level risk perception. Structural-level facilitators included having positive experiences in affirming healthcare settings and having PrEP visits combined with other gender-related healthcare visits. Interventions aiming to increase PrEP uptake and persistence among Black and Latinx transgender women in the U.S. should harness the multiple levels of support exhibited by those who were able to start and persist on PrEP in the face of the myriad social and structural barriers.

Abstract

Gender-based violence (GBV) against transgender and nonbinary (TGNB) persons is a pervasive public health issue. GBV has been linked to mental health problems such as depression and posttraumatic stress disorder (PTSD), as well has risk for HIV seroconversion and HIV treatment nonadherence. However, the impact of GBV on HIV pre-exposure prophylaxis (PrEP) use among TGNB persons has yet to be investigated. In the current study we assessed longitudinal PrEP persistence data from dried blood spots (DBS) collected from 172 racially and ethnically diverse TGNB participants during a 48-week PrEP demonstration project in Southern California from June 2017 to September 2020. Participants were categorized into three levels of PrEP uptake and persistence based on their PrEP levels at the start and end of the study: low-low, high-low, and high-high. Individual-, social-, and structural-level variables were then entered into multinomial logistic regression models to predict levels of PrEP uptake and persistence based on hypotheses informed by syndemic and minority stress theories. The models demonstrated that experience of GBV predicted significantly lower odds of PrEP uptake and persistence and greater PTSD symptoms predicted significantly greater odds of early PrEP discontinuation. Higher levels of coping skills, already being on PrEP at baseline, and being in a steady relationship were associated with greater odds of PrEP uptake and persistence. Implications for future GBV research, advocacy, interventions, and much needed structural changes focused on improving the health and safety of TGNB individuals are discussed.

Abstract

TechStep is a randomized trial of a mobile health interventions targeted towards transgender adolescents. The interventions include a short message system, a mobile-optimized web application, and electronic counseling. The primary outcomes are self-reported sexual risk behaviors and uptake of HIV preventing medication. In order that we may evaluate the efficacy of several different combinations of interventions, the trial has a sequentially randomized design. We use a causal framework to formalize the estimands of the primary and key secondary analyses of the TechStep trial data. Targeted minimum loss-based estimators of these quantities are described and studied in simulation.

Abstract

Young Latino men who have sex with men (MSM) are a highly vulnerable population for HIV infection. Pre-exposure prophylaxis (PrEP) is a novel biomedical HIV prevention tool that may aid in reducing the disparity in HIV incidence among Latino MSM. However, PrEP use is disproportionally low among Latino MSM and, therefore, identifying barriers along the PrEP continuum of care (the "PrEP cascade") would provide insight into how to best deploy PrEP interventions. Syndemics theory is a prominent framework employed in HIV prevention; however, to date, no known studies have applied this theory to PrEP. Thus, the aim of the current study was to explore the association between syndemics and the PrEP cascade, including the degree to which psychosocial and structural syndemic constructs are related to the PrEP cascade. Participants were 151 young Latino MSM (M age = 24 years; SD = 3) residing in San Diego, California, who completed a battery of online self-report measures. Results indicated high levels of syndemic indicators and varying levels of engagement across the PrEP cascade. As syndemic indicators increased, the odds of engagement across the PrEP cascade were significantly lowered. Psychosocial and structural syndemic factors accounted for unique variance in the PrEP cascade. Results highlight the need for combination interventions that address both psychosocial and structural barriers to PrEP use and persistence among young Latino MSM.

Abstract

IntroductionIn the era of HIV treatment as prevention (TasP), evidence-based interventions that optimize viral suppression among people who use stimulants such as methamphetamine are needed to improve health outcomes and reduce onward transmission risk. We tested the efficacy of positive affect intervention delivered during community-based contingency management (CM) for reducing viral load in sexual minority men living with HIV who use methamphetamine.MethodsConducted in San Francisco, this Phase II randomized controlled trial tested the efficacy of a positive affect intervention for boosting and extending the effectiveness of community-based CM for stimulant abstinence to achieve more durable reductions in HIV viral load. From 2013 to 2017, 110 sexual minority men living with HIV who had biologically confirmed, recent methamphetamine use were randomized to receive a positive affect intervention (n = 55) or attention-control condition (n = 55). All individual positive affect intervention and attention-control sessions were delivered during three months of community-based CM where participants received financial incentives for stimulant abstinence. The 5-session positive affect intervention was designed to provide skills for managing stimulant withdrawal symptoms as well as sensitize individuals to natural sources of reward. The attention-control condition consisted of neutral writing exercises and self-report measures.ResultsMen randomized to the positive affect intervention displayed significantly lower log10 HIV viral load at six, twelve and fifteen months compared to those in the attention-control condition. Men in the positive affect intervention also had significantly lower risk of at least one unsuppressed HIV RNA (≥200 copies/mL) over the 15-month follow-up. There were concurrent, statistically significant intervention-related increases in positive affect as well as decreases in the self-reported frequency of stimulant use at six and twelve months.ConclusionsDelivering a positive affect intervention during community-based CM with sexual minority men who use methamphetamine achieved durable and clinically meaningful reductions in HIV viral load that were paralleled by increases in positive affect and decreases in stimulant use. Further clinical research is needed to determine the effectiveness of integrative, behavioural interventions for optimizing the clinical and public health benefits of TasP in sexual minority men who use stimulants such as methamphetamine.

Abstract

Dramatic decreases in HIV transmission are achievable with currently available biomedical and behavioral interventions, including antiretroviral therapy and pre-exposure prophylaxis. However, such decreases have not yet been realized among adolescents and young adults. The Adolescent Medicine Trials Network (ATN) for HIV/AIDS interventions is dedicated to research addressing the needs of youth at high risk for HIV acquisition as well as youth living with HIV. This article provides an overview of an array of efficient and effective designs across the translational spectrum that are utilized within the ATN. These designs maximize methodological rigor and real-world applicability of findings while minimizing resource use. Implementation science and cost-effectiveness methods are included. Utilizing protocol examples, we demonstrate the feasibility of such designs to balance rigor and relevance to shorten the science-to-practice gap and improve the youth HIV prevention and care continua.

Abstract

Although the use of geosocial networking (GSN) applications for relationship seeking is prevalent among sexual minority men (SMM), SMM of color may be vulnerable to sexual racism online. Little is known about how sexual racism relates to SMM of color's identity outness, which is integral to the minority stress model and the focus of this study. Eighty SMM, recruited through social media (53.7% racial/ethnic minority), reported their experiences of race-based discrimination on GSN apps and identity outness. Chi-squared and Fisher's tests examined differences in race-based discrimination online by participants' race/ethnicity. A factorial MANOVA was performed on outness to family, peers, and healthcare providers. Nearly one-third of participants experienced race-based discrimination online. Higher percentages of SMM of color experienced race-based discrimination than White SMM. SMM who experienced race-based discrimination online reported lower outness to family than those who had not. Post-hoc analyses revealed that Asian SMM reported consistently lower outness than other groups. Our findings resonated with the mediation framework of minority stress, suggesting that sexual racism online may be a distal stressor that contributes to the group-specific process of identity outness. This also illustrated the importance of addressing sexual racism on GSN apps to buffer existing stress with outness among SMM of color. [ABSTRACT FROM AUTHOR]

Abstract

This study quantitatively examined factors related to young men who have sex with men (YMSM)'s decisions to use pre-exposure prophylaxis (PrEP) by their history of PrEP use and qualitatively elicited their perspectives on PrEP options. Higher proportions of YMSM who had never used (vs. ever used) PrEP considered the following factors as important in their decisions to use PrEP: (a) Returning to PrEP follow-up visits (p=.02), (b) having to talk about sex/PrEP with providers (p=.013), (c) people assuming they are infected with HIV (p=.021), (d) family finding out about their PrEP use (p=.001), and (e) friends finding out about their PrEP use (p= .008). Through inductive content analysis, qualitative data showed that a higher proportion of YMSM who had never used PrEP (vs. ever used) expressed concerns about HIV stigma from nonaffirming health care providers and the potential risk of inadvertently revealing their LGBTQ1identity to others, which were described as potential barriers to PrEP use. Overall, our findings suggest that future interventions may consider tailoring PrEP messaging to YMSM's history of PrEP use, which may ultimately increase PrEP uptake and adherence.

Abstract

Background/Objective: The aim of this study was to determine the prevalence of high-risk (HR) human papillomavirus (HPV) types by HPV vaccination status and the feasibility of using HPV L1 serology to identify HIV-negative men who have sex with men (MSM) who may be at risk for anal cancer. Methods: This cross-sectional study recruited HIV-negative MSM from a US metropolitan area. The prevalence of HR, quadrivalent, and nonavalent anorectal HPV DNA and HPV L1 serum antibodies was estimated. McNemar's chi-square and kappa statistics were used to determine significant differences in HPV detection between anorectal DNA swabs and HPV L1 serology. Results: Eighty-two men had adequate anorectal swabs and serology samples for analysis. Men who self-reported receipt of the HPV vaccine (35.6%) had detectable L1 HPV antibodies (93.1%) and a lower prevalence of active anal HPV infections (20.7%) compared to those who reported none. Conclusions: If confirmed in larger prospective studies, a combination of HPV vaccination status or HPV L1 serology and anorectal swabs for HR HPV types could identify HIV-negative MSM who do not need to undergo follow-up anal testing.

Abstract

Interactive communications technologies facilitate identity formation and socio-sexual connection among transgender and gender-diverse young people. However, within their communities, variations in technology use along ethno-racial, sexual and gendered lines, and as facilitators of sexual resilience during the early COVID-19 pandemic, remain under-studied. Among N = 230 transgender and gender-diverse young adults, surveyed between October 2020 and September 2021, latent class analyses characterised participants by preferred functional affordances, such as finding dates, sex and friends (Model 1), and by simultaneous account-keeping across social, dating and 'hookup' apps (Model 2). Werron and Ringel's typology of pandemic practices characterised qualitative descriptions of sexual decision-making attributed to COVID-19. Both fit indices favoured two-class solutions. Model 1 detected an n = 89, 43% 'high interactive communications technologies–enabled intimacy' (versus 'low technology-enabled intimacy') class, in which digitally mediated friendships, dates, sexual encounters and gay/lesbian sexualities, predominated. An n = 38, 17% 'high socio-sexual polymedia' (versus 'low polymedia') class in Model 2 was characterised by simultaneous social media, 'hookup' and dating app usage. 'High' subgroups saw statistically significant reductions in sexual partners, with the high polymedia class also associated with reductions in HIV testing. Qualitative results contextualised these reductions as, predominantly, 'responsive' pandemic practices: reactions to stay-at-home orders. [ABSTRACT FROM AUTHOR]
