Acceptability of Event-Driven and Long-Acting HIV Pre-Exposure Prophylaxis Formulations Among Transgender Women Engaged in Street-Based Sex Work in Baltimore, Maryland.

We assessed acceptability of nonoral HIV pre-exposure prophylaxis (PrEP) formulations among transgender women (TW) engaged in street-based sex work in Baltimore, Maryland. In a K-means cluster analysis, TW (N=36) were partitioned into groups characterized by high interest in long-acting injectable PrEP only (Injectable Enthusiasts, 36%), high interest in injectables and subdermal implants (Long-Acting Acceptors, 36%), and low interest across PrEP formulations (Non-Acceptors, 28%). TW's interest in novel PrEP agents varied widely across formulations (range: 22-66%) and clustered around numerous relational, occupational, and structural factors, highlighting the importance of availing multiple PrEP formulations for this impacted population.

Polysubstance Use Profiles and HIV Viremia in a South African Cohort of Female Sex Workers: A Latent Class Analysis.

BACKGROUND: Given intersecting social and structural factors, female sex workers (FSW) exhibit elevated risk of HIV and substance use. However, there is limited study of how distinct substance use typologies influence HIV treatment outcomes among FSW. SETTING: A cross-sectional survey with objective viral load assessments of 1391 FSW enrolled into a treatment optimization-focused trial in Durban, South Africa (2018-2020). METHODS: We used latent class analysis to uncover discrete patterns in past-month self-reported use of the following substances: heavy alcohol use, cannabis, cocaine, crack, ecstasy, methamphetamine, heroin, and Whoonga . We used Wald tests to identify multilevel predictors of latent class membership and multivariable mixture modeling to quantify associations of substance use classes with HIV viremia (≥50 RNA copies/mL). RESULTS: Substance use (87%) and HIV viremia (62%) were highly prevalent. Latent class analysis uncovered 3 polysubstance use profiles: Heavy Alcohol Use Only (∼54%); Cannabis, Heavy Alcohol, & Crack Use (∼28%); and Whoonga & Crack Use (∼18%). Whoonga & Crack Use was associated with social and structural adversities, including homelessness, outdoor/public sex work, HIV stigma, and violence. Relative to Heavy Alcohol Use Only , HIV viremia was significantly higher in the Whoonga & Crack Use class (adjusted odds ratio 1.97, 95% confidence interval: 1.13 to 3.43), but not in the Cannabis, Heavy Alcohol, & Crack Use class (adjusted odds ratio 1.17, 95% confidence interval: 0.74 to 1.86). CONCLUSION: HIV viremia differed significantly across identified polysubstance use profiles among South African FSW. Integrating drug treatment and harm reduction services into HIV treatment programs is key to improving virologic outcomes in marginalized communities.

Individual and Collective Forms of Stigma Resistance: Pathways Between HIV and Sex Work Stigma and Viral Suppression Among Female Sex Workers in the Dominican Republic.

Intersecting forms of stigma including both HIV and sex work stigma have been known to impede HIV prevention and optimal treatment outcomes among FSW. Recent research has indicated that intersectional stigma can be resisted at the community and individual level. We assessed pathways between HIV stigma, sex work stigma, social cohesion and viral suppression among a cohort of 210 FSW living with HIV in the Dominican Republic. Through Poisson regression we explored the relationship between HIV outcomes and internalized, anticipated and enacted HIV and sex work stigma, and resisted sex work stigma. We employed structural equation modeling to explore the direct effect of various forms of stigma on HIV outcomes, and the mediating effects of multi-level stigma resistance including social cohesion at the community level and occupational dignity at the individual level. 76.2% of FSW were virally suppressed and 28.1% had stopped ART at least once in the last 6 months. ART interruption had a significant negative direct effect on viral suppression (OR = 0.26, p < 0.001, 95% CI: 0.13-0.51). Social cohesion had a significant positive direct effect on viral suppression (OR = 2.07, p = 0.046, 95% CI: 1.01-4.25). Anticipated HIV stigma had a significant negative effect on viral suppression (OR = 0.34, p = 0.055, 95% CI: 0.11-1.02). This effect was mediated by the interaction between cohesion and dignity which rendered the impact of HIV stigma on viral suppression not significant. Findings demonstrate that while HIV stigma has a negative impact on viral suppression among FSW, it can be resisted through individual and collective means. Results reinforce the importance of community-driven, multi-level interventions.

PrEP initiation and discontinuation among transgender women in the United States: a longitudinal, mixed methods cohort study.

INTRODUCTION: Transgender women in the United States experience high HIV incidence and suboptimal Pre-exposure prophylaxis (PrEP) engagement. We sought to estimate PrEP initiation and discontinuation rates and characterize PrEP discontinuation experiences among a prospective cohort of transgender women. METHODS: Using a sequential, explanatory, mixed-methods design, 1312 transgender women at risk for HIV acquisition were enrolled from March 2018 to August 2020 and followed through July 2022 (median follow-up 24 months; interquartile range 15-36). Cox regression models assessed predictors of initiation and discontinuation. In-depth interviews were conducted among 18 participants, including life history calendars to explore key events and experiences surrounding discontinuations. Qualitative and quantitative data were integrated to generate typologies of discontinuation, inform meta-inferences and facilitate the interpretation of findings. RESULTS: 21.8% (n = 286) of participants reported taking PrEP at one or more study visits while under observation. We observed 139 PrEP initiations over 2127 person-years (6.5 initiations/100 person-years, 95% CI: 5.5-7.7). Predictors of initiation included identifying as Black and PrEP indication. The rate of initiation among those who were PrEP-indicated was 9.6 initiations/100 person-years (132/1372 person-years; 95% CI: 8.1-11.4). We observed 138 PrEP discontinuations over 368 person-years (37.5 discontinuations/100 person-years, 95% CI: 31.7-44.3). Predictors of discontinuation included high school education or less and initiating PrEP for the first time while under observation. Four discontinuation typologies emerged: (1) seroconversion following discontinuation; (2) ongoing HIV acquisition risk following discontinuation; (3) reassessment of HIV/STI prevention strategy following discontinuation; and (4) dynamic PrEP use coinciding with changes in HIV acquisition risk. CONCLUSIONS: PrEP initiation rates were low and discontinuation rates were high. Complex motivations to stop using PrEP did not consistently correspond with HIV acquisition risk reduction. Evidence-based interventions to increase PrEP persistence among transgender women with ongoing acquisition risk and provide HIV prevention support for those who discontinue PrEP are necessary to reduce HIV incidence in this population.

Variation in Preferences for Long-Acting Injectable Pre-Exposure Prophylaxis Among US Men Who Have Sex with Men: A Latent Class Analysis.

Cabotegravir long-acting injectable HIV pre-exposure prophylaxis (LA PrEP) is efficacious, with a good safety profile, and was approved by the US Food and Drug Administration in December 2021. Understanding variations in potential user preferences for LA PrEP may inform implementation and subsequently improve uptake and community-level effectiveness. HIV-negative, sexually active men who have sex with men (MSM) aged ≥15 years were recruited online for the 2019 American Men's Internet Survey, before LA PrEP approval. Respondents completed a discrete-choice experiment (DCE) with hypothetical LA PrEP attributes (out-of-pocket cost, perceived side effects, injection frequency, perceived stigma, service location). Latent class analysis segmented respondents into groups based on their preferences for the attributes presented, and relative importance of preference weights and willingness-to-pay were calculated. While the majority had never used daily oral PrEP, 73% of the 2489 respondents were very or somewhat likely to use LA PrEP. Three latent classes were identified from 2241 respondents in the DCE. The "side effects-averse" class was the largest group (64% of respondents) and placed 61% relative importance on side effects. The "ambivalent" class (20% of respondents) placed higher importance on stigma (17% of relative importance) than other classes. The "cost-conscious" class (16% of respondents) placed higher relative importance (62%) on cost compared with other attributes and classes. Perceived side effects were an important hypothetical barrier for LA PrEP uptake among a large proportion of potential MSM users. Minimizing out-of-pocket costs is likely to increase uptake and may be important to equitable access. Tailored communication strategies are recommended for the different groups of potential LA PrEP users.

SARS-CoV-2 Infection and Testing Experiences in a Nationwide Sample of Transgender and Gender-Diverse Adults, June-December 2021.

OBJECTIVES: COVID-19 surveillance data are rarely collected or disaggregated by gender identity in the United States. We quantified COVID-19 testing experiences and SARS-CoV-2 infection history among transgender and gender-diverse (TGD) people to inform testing strategies and public health responses. METHODS: From June 14 through December 16, 2021, TGD adults enrolled in a US nationwide online survey with optional SARS-CoV-2 antibody testing. We used multinomial regression analyses to identify correlates of suspected and confirmed SARS-CoV-2 infection (vs no known infection). We identified correlates of inability to access COVID-19 testing when needed using generalized linear models for binomial variables. RESULTS: Participants (N = 2092) reported trans masculine (30.5%), trans feminine (27.3%), and nonbinary (42.2%) gender identities. Ten percent of respondents had a confirmed history of SARS-CoV-2 infection, and 29.8% had a history of suspected SARS-CoV-2 infection. Nonbinary gender (adjusted prevalence ratio [aPR] = 1.68; 95% CI, 1.12-2.53), experiencing homelessness (aPR = 1.65; 95% CI, 1.05-2.60), and food insecurity (aPR = 1.45; 95% CI, 1.03-2.04) were associated with confirmed SARS-CoV-2 infection. Food insecurity (aPR = 1.38; 95% CI, 1.10-1.72), chronic physical health condition (aPR = 1.44; 95% CI, 1.15-1.80), chronic mental health condition (aPR = 3.65; 95% CI, 2.40-5.56), and increased anticipated discrimination scores (aPR = 1.03; 95% CI, 1.01-1.05) were associated with suspected SARS-CoV-2 infection. Thirty-four percent (n = 694 of 2024) of participants reported an inability to access COVID-19 testing when needed, which was associated with Latinx or Hispanic ethnicity, inconsistent telephone access, homelessness, disability, and transportation limitations. The majority (79.4%) reported a complete COVID-19 vaccine course at the time of participation. CONCLUSIONS: Inclusion of TGD people in public health surveillance and tailored public health strategies to address TGD communities' social and structural vulnerabilities may reduce barriers to COVID-19 testing.

Acceptability of multiple modalities of pre-exposure prophylaxis (PrEP) among female sex workers in Tanzania: a mixed-methods study.

OBJECTIVES: Modalities of pre-exposure prophylaxis (PrEP) for HIV prevention offer options to women at high risk including female sex workers (FSW). This study aimed to explore FSW's acceptability and preferences for oral pills, long-acting (LA) injectable and vaginal ring PrEP. DESIGN: Sequential, explanatory, mixed methods. SETTING: Iringa, Tanzania. PARTICIPANTS: FSW aged above 18 were recruited from sex work venues using time-location sampling (n=496); HIV-uninfected (n=293) were included in this analysis. Subsequently, survey participants were recruited for in-depth interviews (n=10) and two focus group discussions (n=20). PRIMARY OUTCOME MEASURES: (1) Acceptability of PrEP (Do you personally think it would be worth it to you to take ART if it could prevent HIV?: yes/no) and (2) preference for LA injectable versus oral pills (If you personally were going to take ART to prevent HIV infection, would you prefer to take it in the form of a daily pill or an injection once every 3 months? Injection/pill). RESULTS: Participants were (92%) unaware of PrEP but 58% thought it would be worth it to personally take PrEP. Acceptability of PrEP was significantly associated with higher social cohesion (aOR 2.12; 95% CI 1.29 to 3.50) and STI symptoms in the past 6 months (aOR 2.52; 95% CI 1.38 to 4.62). Most (88%) preferred LA vs oral PrEP. Qualitative findings revealed generally positive reactions to all types of PrEP, and they were viewed as a welcome backup to condoms. Participants had concerns about pills (burden of daily use, stigma from clients), and the vaginal ring (fear of client noticing and becoming suspicious, fear of infertility) and overall preferred LA-PrEP (less frequent use, easy to hide, belief in higher efficacy). CONCLUSIONS: Offering multiple formulations of PrEP within the context of community-driven HIV prevention interventions among FSW may facilitate increased uptake and adherence. LA injectable PrEP may be a particularly preferred formulation among FSW. TRIAL REGISTRATION NUMBER: NCT02281578.

Prevention-effective adherence trajectories among transgender women indicated for PrEP in the United States: a prospective cohort study.

PURPOSE: Adherence to pre-exposure prophylaxis (PrEP) during periods of PrEP-indication (i.e., prevention-effective adherence) is critical for preventing HIV. We sought to describe factors associated with prevention-effective adherence trajectories among transgender women (TW) to inform PrEP implementation strategies. METHODS: Using data from The LITE American Cohort (n = 728), we performed group-based multi-trajectory modeling (GBMTM) to identify clusters of TW with similar trajectories of PrEP adherence and indication, and sociodemographic, biobehavioral, and structural correlates of each trajectory. RESULTS: We identified five trajectories: (1) consistent indication/no PrEP (15.3%), (2) initial indication/no PrEP (47.1%), (3) declining indication/discontinued PrEP (9.5%), (4) consistent indication/PrEP adherent (18.5%), and (5) increasing indication/initiated PrEP (9.6%). TW diagnosed with an STI were more likely to follow a consistent indication/no PrEP trajectory compared to consistent indication/PrEP adherent trajectory (adjusted Relative Risk Ratio [aRRR], 2.54; 95% confidence interval [CI], 1.16-5.57). TW who experienced homelessness were more likely to follow PrEP discontinuation and initiation trajectories relative to PrEP adherence (aRRR, 2.71; 95% CI, 1.10-6.70 and 2.83; 95% CI, 1.13-7.05, respectively). CONCLUSIONS: Over a quarter of TW followed trajectories suggestive of prevention-effective adherence, while 15% did not initiate PrEP despite consistent indication. Findings highlight missed opportunities for PrEP engagement at STI diagnosis and suggest structural interventions addressing housing instability may improve prevention-effective adherence among TW.

Mapping Interests in Event-Driven and Long-Acting Pre-exposure Prophylaxis Formulations onto the HIV Risk Environment of Street-Based Female Sex Workers: A Latent Class Analysis.

Despite growing availability, HIV pre-exposure prophylaxis (PrEP) uptake and adherence remains suboptimal among female sex workers (FSW) in the United States. Using cross-sectional data from a survey of 236 street-based cisgender FSW in Baltimore, Maryland, we examined interest in event-driven and long-acting PrEP formulations. Latent class analysis identified discrete patterns of interest in five novel PrEP agents. Multinomial latent class regression then examined factors associated with probabilistic class membership. A three-class solution emerged as the best-fit latent class model: Injectable Acceptors (~ 24% of sample), Universal Acceptors (~ 18%), and Non-Acceptors (~ 58%). Compared to Non-Acceptors, Universal Acceptors had significantly (p < 0.05) higher odds of reporting condomless vaginal sex with clients, client condom coercion, and client-perpetrated physical violence. Relative to Non-Acceptors, Injectable Acceptors were distinguished by significantly higher rates of condomless vaginal sex with clients and injection drug use. Expanding PrEP options for FSW could help overcome barriers to PrEP initiation and persistence.

The Importance of Sexual Orientation in the Association Between Social Cohesion and Client Condom Coercion Among Women Who Exchange Sex in Baltimore, Maryland.

Among women who exchange sex (WES), social cohesion is associated with multi-level HIV-risk reduction factors, and client condom coercion (CCC) is associated with increased HIV-risk. Sexual minority WES (SM-WES) face exacerbated HIV-risk, yet relevant research is scant. We examined the role of sexual orientation in the relationship between social cohesion and CCC among cisgender WES (n = 384) in Baltimore, Maryland using stratified logistic regression, controlling for potential confounders. Forty-five percent of WES experienced CCC. SM-WES reported significantly higher social cohesion than heterosexual WES. The relationship between social cohesion and CCC differed by sexual orientation. Among SM-WES, higher social cohesion was independently associated with decreased odds of experiencing CCC, controlling for food insecurity, crack use, police harassment, and method of finding clients. Among heterosexual WES, no significant association was found. Ongoing research and practice with WES should (1) collect sexual orientation data to allow for deeper understanding and tailored interventions, (2) leverage and nurture social cohesion and (3) tailor interventions to populations with attention to sexual orientation.

RESUMEN: Among women who exchange sex (WES), social cohesion is associated with multi-level HIV-risk reduction factors, and client condom coercion (CCC) is associated with increased HIV-riskEntre las mujeres que intercambian sexo (WES), la cohesión social atenúa el riesgo de VIH, y la coerción del uso del condón por parte de clientes (CCC) amplifica el riesgo de VIH. Las WES de minorías sexuales (SM-WES) experiencian un riesgo elevado de VIH, pero las investigaciónes relevantes son pocas. En este papel, examinamos la contribución de la orientación sexual en modificando la relación entre la cohesión social y la CCC entre WES cisgénero (n = 384) en Baltimore, Maryland, utilizando regresión logística estratificada, ajustando por posibles factores de confusión. Cuarenta y cinco por ciento de WES reportaron experiencias de CCC. SM-WES exhibieron cohesión social significativamente más alta que las WES heterosexuales. La relación entre la cohesión social y CCC fue moderada por la orientación sexual. Entre SM-WES, la cohesión social se asoció independientemente con menores probabilidades de reportar experiencias de CCC, ajustando por la inseguridad alimentaria, el uso de crack, el acoso policial y el método de encontrar a clientes. Entre las WES heterosexuales, la misma asociación no fue significativa. La investigación y la práctica con WES deben 1) recopilar datos de orientación sexual para permitir una comprensión más profunda e intervenciones personalizadas, 2) aprovechar y fomentar la cohesión social y 3) adaptar las intervenciones a estas poblaciones con atención a la orientación sexual.

Gender affirming hormone therapy dosing behaviors among transgender and nonbinary adults.

Gender-affirming hormones have been shown to improve psychological functioning and quality of life among transgender and nonbinary (trans) people, yet, scant research exists regarding whether and why individuals take more or less hormones than prescribed. Drawing on survey data from 379 trans people who were prescribed hormones, we utilized multivariable logistic regression models to identify factors associated with hormone-dosing behaviors and content analysis to examine the reasons for dose modifications. Overall, 24% of trans individuals took more hormones than prescribed and 57% took less. Taking more hormones than prescribed was significantly associated with having the same provider for primary and gender-affirming care and gender-based discrimination. Income and insurance coverage barriers were significantly associated with taking less hormones than prescribed. Differences by gender identity were also observed. Addressing barriers to hormone access and cost could help to ensure safe hormone-dosing behaviors and the achievement trans people's gender-affirmation goals.

"She is the one who knows": A qualitative exploration of oral and injectable PrEP as part of a community empowerment approach to HIV prevention among female sex workers in the Dominican Republic and Tanzania.

Despite documented interest among female sex workers (FSW), uptake of oral pre-exposure prophylaxis (PrEP) for HIV prevention has been low. Recent trials and regulatory approval of long-acting injectable (LAI) PrEP offer new hope for the potential of this biomedical intervention. We examined FSW's PrEP-related interest and preferences regarding both oral and LAI PrEP situating these dynamics within their specific social and occupational realities. We conducted this work using qualitative methods across two distinct contexts by conducting 40 in-depth interviews with FSW in Tanzania and the Dominican Republic. Textual data was coded using iterative thematic content analysis. Analytic summaries were developed and reviewed to identify recurring themes. We systematically organized themes within each country and then compared across settings. Women in both settings expressed strong interest in PrEP seeing it as an important option to protect themselves in their work. Most participants preferred LAI PrEP due to expectations of reduced stigma and concerns about daily pill adherence and side effects. Occupational factors such as alcohol use, overnight dates with clients, and fear of violence from clients were identified as barriers to daily oral PrEP. LAI PrEP was seen as having the potential to reduce stress related to oral PrEP. Women who preferred pills discussed fear of needles, skepticism about the injections, and others relayed that taking a daily pill would not be challenging for them. There was a pre-dominant sentiment that women know best whether they are better suited for oral or LAI PrEP. Participants stressed the importance of FSW understanding both options to ensure informed decision-making around PrEP and described community-led peer education as key to delivering trusted information. Community empowerment approaches led by FSW which address structural and psychosocial constraints and promote safe work environments may facilitate equitable access and uptake of PrEP among FSW across settings.

Prevalence and associations of COVID-19 testing in an online sample of transgender and non-binary individuals.

BACKGROUND: Testing for COVID-19 and linkage to services is fundamental to successful containment and control of transmission. Yet, knowledge on COVID-19 testing among transgender and non-binary communities remains limited. METHODS: Between October 2020 and November 2020, we examined the prevalence and associations of COVID-19 testing in an online sample of transgender and non-binary people (n=536). Multivariable hierarchical logistic regression analyses examined associations between COVID-19 testing and participants' sociodemographic, mental health, substance use, gender affirmation, economic changes and healthcare experiences. RESULTS: Prevalence of COVID-19 testing in this sample was 35.5% (n=190/536). In the final model, transgender and non-binary participants from upper socioeconomic income background and Europe, who reported having active alcohol use disorder, limited access to gender-affirming surgery, had more than 20% reduction in income, and experienced mistreatment in a health facility due to gender identity had significantly increased odds of COVID-19 testing (all p<0.05); those who reported recent tobacco use had significantly lower odds of COVID-19 testing (p=0.007). CONCLUSIONS: These findings highlight structural disparities in COVID-19 testing and reinforce the importance of increasing testing strategies for transgender and non-binary populations.

Family planning use and correlates among female sex workers in a community empowerment HIV prevention intervention in Iringa, Tanzania: a case for tailored programming.

BACKGROUND: Female sex workers in sub-Saharan Africa face high unmet need for family planning and higher risk for unintended pregnancy. Community empowerment HIV prevention approaches have the potential to increase family planning uptake and present an opportunity to integrate HIV, reproductive health, and contraception. This article describes family planning use and pregnancy among female sex workers in Iringa, Tanzania and evaluates whether engagement in a community empowerment HIV prevention program is associated with contraceptive use. METHODS: This study consists of secondary analysis from a two-community randomized controlled trial following a longitudinal cohort over 18 months. We implemented a year-long community empowerment intervention consisting of 1) a community-led drop-in-center; 2) venue-based peer education, condom distribution, and HIV testing; 3) peer service navigation; 4) sensitivity trainings for providers and police; and 5) text messages to promote engagement. Additionally, monthly seminars were held at the drop-in-center, one of which focused on family planning. Modified Poisson regression models were used to estimate the association between program exposure and family planning use in the intervention arm. (Trials Registration NCT02281578, Nov 2, 2014.) RESULTS: Among the 339 participants with follow-up data on family planning, 60% reported current family planning use; 6% reported dual use of modern contraception and condoms; over 90% had living children; and 85% sought antenatal care at their most recent pregnancy. Among the 185 participants in the intervention arm, the adjusted relative risk (aRR) of family planning use among female sex workers who reported ever attending the Shikamana drop-in-center and among female sex workers who reported attending a family planning-related workshop was respectively 26% (aRR 1.26 [95% Confidence Interval (CI): 1.02-1.56]) and 36% (aRR 1.36 [95%CI: 1.13-1.64) higher than among those who had not attended. CONCLUSION: There is a clear need for family planning among this population. General program exposure and exposure to a family planning workshop were associated with higher family planning use, which suggests that community empowerment models have potential to increase family planning uptake for this vulnerable group.

Gender-affirming care, mental health, and economic stability in the time of COVID-19: A multi-national, cross-sectional study of transgender and nonbinary people.

BACKGROUND: Transgender and nonbinary people are disproportionately affected by structural barriers to quality healthcare, mental health challenges, and economic hardship. This study examined the impact of the novel coronavirus disease (COVID-19) crisis and subsequent control measures on gender-affirming care, mental health, and economic stability among transgender and nonbinary people in multiple countries. METHODS: We collected multi-national, cross-sectional data from 964 transgender and nonbinary adult users of the Hornet and Her apps from April to August 2020 to characterize changes in gender-affirming care, mental health, and economic stability as a result of COVID-19. We conducted Poisson regression models to assess if access to gender-affirming care and ability to live according to one's gender were related to depressive symptoms, anxiety, and changes in suicidal ideation. RESULTS: Individuals resided in 76 countries, including Turkey (27.4%, n = 264) and Thailand (20.6%, n = 205). A majority were nonbinary (66.8%, n = 644) or transfeminine (29.4%, n = 283). Due to COVID-19, 55.0% (n = 320/582) reported reduced access to gender-affirming resources, and 38.0% (n = 327/860) reported reduced time lived according to their gender. About half screened positive for depression (50.4%,442/877) and anxiety (45.8%, n = 392/856). One in six (17.0%, n = 112/659) expected losses of health insurance, and 77.0% (n = 724/940) expected income reductions. The prevalence of depressive symptoms, anxiety, and increased suicidal ideation were 1.63 (95% CI: 1.36-1.97), 1.61 (95% CI: 1.31-1.97), and 1.74 (95% CI: 1.07-2.82) times higher for individuals whose access to gender-affirming resources was reduced versus not. DISCUSSION: The COVID-19 crisis is associated with reduced access to gender-affirming resources and the ability of transgender and nonbinary people to live according to their gender worldwide. These reductions may drive the increased depressive symptoms, anxiety, and suicidal ideation reported in this sample. To improve health of transgender and nonbinary communities, increased access to gender-affirming resources should be prioritized through policies (e.g., digital prescriptions), flexible interventions (e.g., telehealth), and support for existing transgender health initiatives.

Mobility for sex work and recent experiences of gender-based violence among female sex workers in Iringa, Tanzania: A longitudinal analysis.

Female sex workers are highly mobile, which may influence their risk of experiencing physical and sexual violence. However, there remains a paucity of research, particularly longitudinal, from Sub-Saharan Africa exploring mobility and gender-based violence among female sex workers. To address this gap, this study examined the longitudinal relationship between work-related mobility and recent experience of physical or sexual gender-based violence from a client or partner among female sex workers in Iringa, Tanzania. A secondary data analysis was conducted using baseline and 18-month follow-up data from Project Shikamana, a community empowerment-based combination HIV prevention intervention. Responses from 387 female sex workers aged 18 years and older participating in both baseline and follow-up were analyzed. Unadjusted and adjusted Poisson regression models with robust variance estimations, accounting for clustering of female sex workers' responses over time, were fit. Final models adjusted for socio-demographic characteristics and aspects of participants' living situations and work environments. Recent physical or sexual violence from a client or partner was common (baseline: 40%; follow-up: 29%). Twenty-six percent of female sex workers at baseline, and 11% at follow-up, had recently traveled outside of Iringa for sex work. In the final adjusted longitudinal model, female sex workers recently mobile for sex work had a 25% increased risk of any recent experience of physical or sexual gender-based violence when compared with their non-mobile counterparts (adjusted incidence rate ratio: 1.25; 95% CI: 1.03-1.53; p<0.05). Interventions must identify ways-such as mobile support services, linkages and referrals to health and other social services while traveling, or the use of mobile or digital technology-to address mobile female sex workers' unique needs while traveling. Future quantitative and qualitative research is needed to understand the context of female sex workers' mobility and how and why mobility influences risk environments and experiences of gender-based violence.

HIV treatment engagement in the context of COVID-19: an observational global sample of transgender and nonbinary people living with HIV.

BACKGROUND: HIV services, like many medical services, have been disrupted by the COVID-19 pandemic. However, there are limited data on the impacts of the COVID-19 pandemic on HIV treatment engagement outcomes among transgender (trans) and nonbinary people. This study addresses a pressing knowledge gap and is important in its global scope, its use of technology for recruitment, and focus on transgender people living with HIV. The objective of this study is to examine correlates of HIV infection and HIV treatment engagement outcomes (i.e., currently on ART, having an HIV provider, having access to HIV treatment without burden, and remote refills) since the COVID-19 pandemic began. METHODS: We utilized observational data from the Global COVID-19 Disparities Survey 2020, an online study that globally sampled trans and nonbinary people (n = 902) between April and August 2020. We conducted a series of multivariable logistic regressions with lasso selection to explore correlates of HIV treatment engagement outcomes in the context of COVID-19. RESULTS: Of the 120 (13.3%) trans and nonbinary people living with HIV in this survey, the majority (85.8%) were currently on HIV treatment. A smaller proportion (69.2%) reported having access to an HIV provider since COVID-19 control measures were implemented. Less than half reported being able to access treatment without burdens related to COVID-19 (48.3%) and having the ability to remotely refill HIV prescription (44.2%). After adjusting for gender in the multivariable models, younger age and anticipated job loss were significantly associated with not having access to HIV treatment without burden. Outcomes also significantly varied by geographic region, with respondents reporting less access to an HIV provider in nearly every region outside of South-East Asia. CONCLUSION: Our results suggest that currently taking ART, having access to an HIV provider, and being able to access HIV treatment without burden and remotely refill HIV medication are suboptimal among trans and nonbinary people living with HIV across the world. Strengthening support for HIV programs that are well-connected to trans and nonbinary communities, increasing remote access to HIV providers and prescription refills, and providing socioeconomic support could significantly improve HIV engagement in trans and nonbinary communities.

Characterising the impact of COVID-19 environment on mental health, gender affirming services and socioeconomic loss in a global sample of transgender and non-binary people: a structural equation modelling.

BACKGROUND: We characterised the impact of COVID-19 on the socioeconomic conditions, access to gender affirmation services and mental health outcomes in a sample of global transgender (trans) and non-binary populations. METHODS: Between 16 April 2020 and 3 August 2020, we conducted a cross-sectional survey with a global sample of trans and non-binary people (n=849) through an online social networking app. We conducted structural equational modelling procedures to determine direct, indirect and overall effects between poor mental health (ie, depression and anxiety) and latent variables across socioecological levels: social (ie, reduction in gender affirming services, socioeconomic loss impact) and environmental factors (ie, COVID-19 pandemic environment). RESULTS: Anxiety (45.82%) and depression (50.88%) in this sample were prevalent and directly linked to COVID-19 pandemic environment. Adjusted for gender identity, age, migrant status, region, education and level of socioeconomic status, our final model showed significant positive associations between relationships of (1) COVID-19 pandemic environment and socioeconomic loss impact (ß=0.62, p<0.001), (2) socioeconomic loss impact and reduction in gender affirming services (ß=0.24, p<0.05) and (3) reduction in gender affirming services and poor mental health (ß=0.19, p<0.05). Moreover, socioeconomic loss impact and reduction in gender affirming services were found to be partial mediators in this model. CONCLUSION: The study results supported the importance of bolstering access to gender affirming services and strengthening socioeconomic opportunities and programmatic support to buffer the impact of COVID-19 pandemic environment on poor mental health among trans and non-binary communities globally.

Development of the Experiences of Sex Work Stigma Scale Using Item Response Theory: Implications for Research on the Social Determinants of HIV.

While HIV stigma has received significant attention, limited work has been conducted on the measurement of intersecting stigmas. We developed the Experiences of Sex Work Stigma (ESWS) scale in the Dominican Republic (DR) and Tanzania. We conducted in-depth interviews with 20 female sex workers (FSW) per country to identify scale domains followed by cognitive debriefing interviews to assess content validity. Items were administered in a survey to FSW in DR (n = 211) and Tanzania (n = 205). Factor analysis established four sex work stigma domains including: shame (internalized), dignity (resisted), silence (anticipated) and treatment (enacted). Reliability across domains ranged from 0.81 to 0.93. Using item response theory (IRT) we created context-specific domain scores accounting for differential item functioning between countries. ESWS domains were associated with internalized HIV stigma, depression, anxiety, sexual partner violence and social cohesion across contexts. The ESWS is the first reliable and valid scale to assess multiple domains of sex work stigma and can be used to examine the effects of this form of intersectional stigma on HIV-related outcomes across settings.
