RESUMEN
Introduction: Little is known about differences in HIV risk for trans women by partner gender, particularly with respect to social determinants and partner-level circumstances that affect behavior. We examined differences in demographic, social determinants, and HIV-related risk behaviors for trans women with cis men and trans women sexual partners. Materials and Methods: Data are from a cross-sectional survey of trans women and their sexual partners conducted between April 2020 and January 2021. Interviews were held remotely during shelter-in-place due to Covid-19 via videoconference. Analysis characterizedassociations between HIV risk and protective behaviors comparing trans women with cisgender men partners to trans women with non-cisgender sexual partners. Results: A total of 336 sexual partners were identified from 156 trans women. Trans women with cis men partners had significantly less education and employment and more incarceration and recidivism than trans women with trans women partners. Trans women and their cisgender men partners had shared experiences of unstable housing, incarceration, and HIV. Trans women with cisgender men partners reported significantly more sex exchange partners, receptive condomless sex, receptive or insertive condomless sex while using substances, and HIV infection compared to trans women with trans women partners. Conclusions: Trans women with cisgender men sexual partners faced higher HIV risk than trans women with trans women sexual partners. These risks may be related to the social and economic drivers that both trans women and their cis men partners faced, including barriers to education and employment, along with incarceration and recidivism. Interventions focused on economic stability, workforce development and post incarceration re-entry support for housing and employment for trans women with cis men partners and the cisgender men partners as well may have the most impact on reducing HIV risk and incidence.
RESUMEN
Purpose: Sex work is a common form of work among young trans women (YTW). Methods: Using an occupational health frame, we measured associations between demographics, sex work, and vocational outcomes in 18-month visit data from the SHINE study (n=263, San Francisco). Results: Overall, 41.8% reported lifetime sex work, primarily escorting/paid sex. Motivations included "better pay" and "can't get a job due to gender discrimination." Occupational injuries included anxiety (53.6%) and depression (50%), with significantly higher relative risk for YTW doing multiple types of sex work. Criminalization experiences (i.e., incarceration, arrests, and police interaction) were common. Conclusion: Results echo calls for sex worker-affirming mental health care for YTW.
RESUMEN
Stigma towards trans women in Nepal creates individual and system-level risks for HIV. A critical protective factor is access to HIV prevention. Research is needed to determine the impact of stigma on HIV testing among trans women in Nepal. We conducted a secondary analysis of data collected using respondent driven sampling in 2019 on HIV risk among trans women in Nepal. Data analysis was restricted to trans women who were HIV negative at testing through the parent study. Descriptive statistics, tests for bivariable associations between HIV testing and stigma variables, and binomial Poisson regression were conducted to examine HIV testing outcomes. There were 173 participants who tested negative for HIV in our sample. The majority were under age 35 (59%) and most had a grade school education or less (64.7%). No trans women were homeless and most rented a room (70.5%) or owned their home (19.7%). The majority were currently sex workers (57.8%). Almost all HIV-negative trans women had ever been tested for HIV (90.8%), but only 53.5% in the last 3 months. The most frequently cited reason for not having been tested was thinking they were at low risk for HIV (40.9%) and being afraid of receiving a positive test result (22.7%). HIV and anti-trans stigma were high across most measures, including that almost all (94.2%) believed that most people in Nepal would discriminate against people with HIV. And most participants thought trans women were not accepted in Nepali Society (65.9%). Most participants also reported high social support (70.5%). Social cohesion among participants varied, with most experiencing medium (41.6%) or high (33.5%) social cohesion. Just over half had high social participation (55.5%). Participants who reported current sex work had lower prevalence of not testing for HIV in the last 3 months (prevalence ratio, PR = 0.54, 95% confidence interval, 95%CI = 0.32-0.92, p = 0.02). Every one-unit increase in social cohesion was associated with 1.05 times the prevalence of not testing for HIV in the last 3 months (95%CI = 1.01-1.09, p-value = 0.02). Trans women who did sex work were more likely to be HIV tested while those who were more socially connected to peers were less likely to have recently been tested for HIV. HIV stigma may result in fear of social rejection from peers if one tests positive. Interventions that focus on addressing stigma within trans women's social networks and strategies to mitigate HIV stigma in society may result in increased frequency of HIV testing among trans women in Nepal.
RESUMEN
This study characterized the prevalence of transphobic adverse childhood experiences (ACEs) among young trans women (YTW) and assessed its relationship with poor mental health and sexual risk. A survey was administered between 2012 and 2014 to 300 YTW aged 16-24 living in the San Francisco Bay Area. Transphobic childhood verbal abuse, physical abuse, and high transphobic childhood adversity were endemic, and we found strong associations with depression, posttraumatic stress disorder, and any and receptive anal intercourse. ACEs may be critical social determinants of mental and sexual health for YTW and validated measures to screen for ACEs are needed, along with interventions that provide gender-affirmative support for parents.
RESUMEN
Background: The novel coronavirus (COVID-19) is negatively impacting vulnerable and marginalized communities. Growing research among sexual and gender minority communities shows increased COVID-19 risk and burden due to underlying social structure factors, however, not as much is known about the impact on trans women. Our team gathered data on COVID-19 risk, self-reported prevalence, and testing behaviors as part of an ongoing study of trans women's HIV risk and partnerships to fill this gap in data. Methods: This is a secondary analysis of data from The Partners Study, a study of HIV risk and transmission among trans women and their sexual partners in the San Francisco Bay Area. We collected COVID-19-related data from 87 trans women from July 2020 to January 2021. Participants were asked whether they were tested for COVID-19, had symptoms, or tested positive for the virus between March 2020 to the time they were screened to participate for a survey interview. Results: The majority of trans women did not report experiencing COVID-19 symptoms (85.05%, n=74/87) since March 2020. More than half had been tested for COVID-19 (68.9%, n=60/87). Overall, we found a COVID-19 prevalence of 8.33% (n=5/60) among those who received a COVID-19 test. Public Health Implications: The COVID-19 prevalence among trans women in our sample was higher than in other gender groups in San Francisco, suggesting that trans women may be disproportionately impacted by this disease. More research is needed to determine the impact of COVID-19 on trans women, and to develop strategies to increase testing and vaccinations among vulnerable communities preventing onward spread.
RESUMEN
Cell manufacturing facilities need to define the potency of mesenchymal stromal cells (MSCs) as cellular therapeutics in advanced clinical trials or marketing approval. Since MSCs' mechanism of action in humans is not well defined, more than a single functional property of MSCs needs to be captured as a surrogate measure of potency utilizing assay matrix technologies. However, the current limitation is the sole investigation of MSC-mediated T-cell suppression as a surrogate measure of potency. We investigated the effect of MSCs on B-cell matrix responses to be incorporated into the assay matrix potency analytical system. Our results demonstrate that MSCs inhibit B-cell differentiation and block pan-antibody secretion upon activation of B cells in the PBMCs. In contrast, MSCs are inferior in blocking B-cell matrix responses when purified B cells are used. Mechanistic analysis has demonstrated that MSC-mediated inhibition of B-cell matrix responses is non-contact dependent and Tryptophan metabolic pathway plays a major role, akin to the mechanism of MSC-mediated T-cell suppression. MSCs also inhibit both T-cell and B-cell responses when both of these lymphoid populations are concurrently activated in the PBMCs. Secretome analysis of MSC and T/B cell-activated PBMC cocultures identified direct and inverse correlative matrix signatures between humoral antibody isotypes and secretory molecules. The current analysis of the combined and concomitant investigation of T-cell and B-cell matrix responses fulfills the potency assay matrix strategy by incorporating MSCs' interaction with more than a single inflammatory immune responder.

BACKGROUND: The HIV epidemic has revealed considerable disparities in health among sexual and gender minorities of color within the Unites States, disproportionately affecting cisgender men who have sex with men (MSM) and trans women. Social inequities further disadvantage those with intersectional identities through homophobia, antitrans discrimination, and racism, shaping not only those at risk for HIV infection but also HIV prevention and care outcomes. Digital interventions have great potential to address barriers and improve HIV care among cisgender MSM and trans women; however, efficacy of digital HIV care interventions vary and need further examination. OBJECTIVE: This study assessed the 12-month efficacy of a 6-month digital HIV care navigation intervention among young people living with HIV in San Francisco, California. We examined dose-response relationships among intervention exposure (eg, text messaging), viral suppression, and mental health. Health electronic navigation (eNav) is a 6-month, text message-based, digital HIV care navigation intervention, in which young people living with HIV are connected to their own HIV care navigator through text messaging to improve engagement in HIV primary care. METHODS: This study had a single-arm, prospective, pre-post design. Eligibility criteria for the study included the following: identifying as cisgender MSM or trans women, being between the ages of 18 and 34 years, being newly diagnosed with HIV, or not being engaged or retained in HIV care or having a detectable viral load. We assessed and analyzed sociodemographics, intervention exposure, and HIV care and mental health outcome data for participants who completed the 6-month Health eNav intervention. We assessed all outcomes using generalized estimating equations to account for within-subjects correlation, and marginal effects of texting engagement on all outcomes were calculated over the entire 12-month study period. Finally, we specified an interaction between texting engagement and time to evaluate the effects of texting engagement on outcomes. RESULTS: Over the entire 12-month period, this study shows that every one-text increase in engagement was associated with an increased odds of undetectable viral load (adjusted odds ratio 1.01, 95% CI 1.00-1.02; P=.03). Mean negative mental health experiences decreased significantly at 12 months compared to baseline for every one-text increase in engagement (coefficient on interaction term 0.97, 95% CI 0.96-0.99; P<.01). CONCLUSIONS: Digital care navigation interventions including Health eNav may be a critical component in the health delivery service system as the digital safety net for those whose social vulnerability is exacerbated in times of crisis, disasters, or global pandemics owing to multiple social inequities. We found that increased engagement in a digital HIV care navigation intervention helped improve viral suppression and mental health-intersecting comorbid conditions-6 months after the intervention concluded. Digital care navigation may be a promising, effective, sustainable, and scalable intervention. INTERNATIONAL REGISTERED REPORT IDENTIFIER (IRRID): RR2-10.2196/16406.

BACKGROUND: Trans women have high HIV prevalence and lag behind 90-90-90 targets for HIV care. In San Francisco in 2017, 96% of trans women were aware of their status, 75% were on antiretroviral therapy, 88% had viral suppression. Initiatives to address gaps include peer navigators, free gender-affirming surgery, and housing. Our study updates HIV prevalence and engagement in care among trans women. METHODS: Cross-sectional community-based survey of trans women living in San Francisco sampled by respondent-driven sampling, 7/2019-2/2020 (N = 201). Eligibility was: self-identified trans women or other gender and assigned male at birth; living in San Francisco; English/Spanish-speaking; and 18 years or older. RESULTS: HIV prevalence was 42.3% (95%CI 35.4.-49.4) and associated with having a partner who injected drugs (adjusted odds ratio [AOR] 3.30, 95%CI 1.58-6.90), ever injected drugs (AOR 2.28, 95%CI 1.06-4.89), cost not a barrier to healthcare (AOR 2.63, 95%CI 1.02-6.67), emotional support from family (AOR 2.85, 95%CI 1.43-5.65), and Black/African-American (AOR 2.59, 95%CI 1.16-5.79). Of trans women with HIV, 92.9% were previously diagnosed, 89.9% were on ART, 91.5% reported viral suppression. CONCLUSIONS: Trans women met 90-90-90 targets in 2020, at 93-90-92. Interventions need to reach Black/African-American trans women, trans women who inject drugs, and partners of trans women.

BACKGROUND: To determine if improvements in social determinants of health for trans women and decreases in transphobic discrimination and violence occurred over three study periods during which extensive local programs were implemented to specifically address longstanding inequities suffered by the transgender community. METHODS: Interviewer-administered surveys from repeated cross-sectional Transwomen Empowered to Advance Community Health (TEACH) studies in 2010, 2013 and 2016-2017 in San Francisco collected experiences with transphobia violence and discrimination. Respondent-driven sampling was used to obtain a sample of participants who identified as a trans woman. RESULTS: Violence due to gender identity was prevalent; in each study period, verbal abuse or harassment was reported by over 83% of participants, and physical abuse or harassment was reported by over 56%. Adverse social determinants of health including homelessness, living below the poverty limit, methamphetamine use, depression, PTSD, and anxiety all significantly increased from 2010 to 2016. When testing for trends, housing discrimination and physical violence were both more likely in 2016-2017 compared to the two earlier study periods. Housing discrimination (aOR 1.41, 95% CI 1.00-1.98) and physical violence due to gender identity/presentation (aOR 1.39, 95% CI 1.00-1.92) both significantly increased from 2010 to 2016. CONCLUSION: Our findings are particularly alarming during a period when significant public health resources and community-based initiatives specifically for trans women were implemented and could have reasonably led us to expect improvements. Despite these efforts, physical violence and housing discrimination among trans women worsened during the study periods. To ensure future improvements, research and interventions need to shift the focus and burden from trans people to cisgender people who are the perpetuators of anti-trans sentiment, stigma, discrimination and victimization.

Despite high HIV prevalence, the reasons trans women acquire HIV are not well understood. Trans women are often mis-classified or aggregated with men who have sex with men (MSM) in epidemiologic studies and HIV surveillance data. Trans women enrolled in the 2019/2020 National HIV Behavioral Surveillance Study in San Francisco were asked an open-ended question about how they were infected with HIV. The most common responses were "Sex with a straight cisgender man partner when the respondent identified as a trans woman" (43.0%); "Sexual assault" (13.9%); "Injection drug use (IDU)" (10.1%); "IDU or sexual contact" (7.6%) and "Sex with a partner who injected drugs" (7.6%). Sex with a cisgender man partner prior to identifying as a trans women (MSM contact) was not mentioned by any respondent. HIV prevention strategies targeting MSM will fail to reach trans women and many of their cisgender men partners.
RESUMEN: A pesar de la alta prevalencia del VIH, las razones por las que las mujeres trans adquieren el VIH no se comprenden bien. Las mujeres trans a menudo se clasifican erróneamente o se agregan a los hombres que tienen sexo con hombres (HSH) en los estudios epidemiológicos y en los datos de vigilancia del VIH. A las mujeres trans inscritas en el Estudio Nacional de Vigilancia del Comportamiento del VIH 2019/2020 en San Francisco se les hizo una pregunta abierta sobre cómo se infectaron con el VIH. Las respuestas más comunes fueron "Sexo con una pareja heterosexual de hombre cisgénero cuando el encuestado se identificó como una mujer trans" (43,0%); "Agresión sexual" (13,9%); "Uso de drogas inyectables (UDI)" (10,1%); "UDI o contacto sexual" (7,6%) y "Sexo con pareja que se inyecta drogas" (7,6%). Ningún encuestado mencionó el sexo con una pareja hombre cisgénero antes de identificarse como mujer trans (contacto HSH). Las estrategias de prevención del VIH dirigidas a los HSH no llegarán a las mujeres trans ni a muchas de sus parejas masculinas.

BACKGROUND: Pre-exposure prophylaxis (PrEP) uptake among trans people to date has been low. Recommendations implemented in San Francisco to offer PrEP with feminizing hormones have not led to improvement of PrEP uptake in trans communities. New delivery models may be needed. The aim of this study was to examine whether a PrEP-only clinic was more likely to serve trans people at highest risk of HIV than trans-affirming primary care clinics. METHODS: Participants were recruited between 2017 and 2019 as part of a PrEP demonstration project in the San Francisco Bay Area. Survey data including sociodemographics, HIV-related risk behavior, barriers to PrEP, and self-reported PrEP adherence were collected at baseline, 3 months, and 6 months for all participants. Bivariable Poisson regression models were used to examine differences between participants in the primary care clinics and PrEP-only clinic delivered to participants. RESULTS: Baseline survey data were collected from 153 participants. Those with a higher number of sexual partners were significantly more likely to use the PrEP-only clinic rather than the primary care clinics. Participants with higher perceived HIV risk and those who engaged in sex work were also more likely to use the PrEP-only clinic compared with the primary care clinic. Medical mistrust was higher at baseline among participants of the PrEP-only clinic. PrEP adherence was not significantly different by delivery model. Few participants identified PrEP barriers, such as interactions with feminizing hormones, to be determinants of PrEP uptake. CONCLUSIONS: A PrEP-only delivery model could improve PrEP uptake and may better meet the needs of trans people who could most benefit from PrEP.

BACKGROUND: Trans women experience high rates of gender-based violence (GBV)-a risk factor for adverse health outcomes. Transphobic hate crimes are one such form of GBV that affect trans women. However, little is understood about factors that shape transphobic hate crimes and racial/ethnic variation in these experiences. To contextualize GBV risk and police reporting, we examined self-reported types and correlates of transphobic hate crimes by racial/ethnic group of trans women in the San Francisco Bay Area. METHODS: From 2016 to 2018, trans women participated in a longitudinal cohort study of HIV. Secondary data analyses (N = 629) examined self-reported experiences of transphobic hate crimes (i.e., robbery, physical assault, sexual assault, and battery with weapon) by race/ethnicity, and whether hate crimes were reported to the police. Chi-square tests and simple logistic regression examined demographic, sociocultural, and gender identity factors associated with transphobic violence experiences and police reporting. RESULTS: About half (45.8%) of participants reported ever experiencing a transphobic hate crime; only 51.1% of these were reported to the police. Among those who reported a hate crime experience, Black (47.9%) and Latina (49.0%) trans women reported a higher prevalence of battery with a weapon; White (26.7%) and trans women of "other" race/ethnicities (25.0%) reported a higher prevalence of sexual assault (p = 0.001). Having one's gender questioned, history of sex work, homelessness as a child and adult, and a history incarceration were associated with higher odds of experiencing a transphobic hate crime. Trans women who felt their gender identity questioned had lower odds of reporting a hate crime to the police compared to those did not feel questioned. CONCLUSIONS: A high proportion of trans women experienced a transphobic hate crime, with significant socio-structural risk factors and racial differences by crime type. However, crimes were underreported to the police. Interventions that address structural factors, especially among trans women of color, can yield violence prevention benefits.

BACKGROUND: Transgender women worldwide have the highest prevalence of HIV and the lowest access to prevention among groups at risk of HIV. However, few longitudinal studies have directly measured HIV incidence and identified predictors of HIV acquisition among transgender women. SETTING: São Paulo, Latin America's largest city. METHODS: We conducted a longitudinal study among transgender women in São Paulo. Participants were recruited by a long-chain peer referral process from May 2017 to July 2019. Those aged 18 years and older and who were HIV-negative at baseline were retested every 6 months up to 18 months. HIV incidence was calculated by dividing the number of seroconversions by the person-years (PYs) of follow-up; 95% confidence intervals (CIs) were constructed assuming a Poisson distribution. Conditional maximum likelihood ratios assessed differences in HIV incidence by risk factors. RESULTS: A racially/ethnically diverse sample of 545 HIV-negative transgender women was enrolled. In 485.5 PYs of follow-up, 13 seroconversions were observed, yielding an incidence of 2.68 per 100 PYs (95% CI: 1.43 to 4.58). HIV incidence was significantly higher among transgender women aged 18-24 years (rate ratio 3.85, 95% CI: 1.24 to 12.93) and among those who engaged in sex work in the preceding month (rate ratio 5.90, 95% CI: 1.71 to 26.62). CONCLUSIONS: HIV transmission continues at a high rate among transgender women in Brazil. Factors such as young age, lower level of education, and limited employment opportunities may lead to dependence on sex work that in turn increases HIV risk. Transgender-friendly prevention services, particularly programs delivering pre-exposure prophylaxis, are urgently needed.

BACKGROUND: Alcohol consumption and stimulant use are major public health problems and contribute to morbidity and mortality in the United States. To inform interventions for substance use, there is a need to identify the day-level correlates of substance use by collecting repeated measures data in one's natural environment. There is also a need to use crowdsourcing platforms like Amazon Mechanical Turk (MTurk) to efficiently engage larger populations of people who use alcohol and stimulants in research. OBJECTIVE: We aimed to (1) utilize daily diaries to examine the temporal relationship between day-level cravings for alcohol and stimulant/substance use (ie, heavy drinking or any drug use) in a given day over 14 days and (2) assess whether depression, negative affect, and self-esteem measured at baseline predict substance use in a given day over 14 days among people who use alcohol and/or stimulants in the United States. METHODS: Individuals aged ≥18 years in the United States, who reported alcohol or stimulant (ie, cocaine, crack cocaine, and methamphetamine) use in the past year, were recruited using MTurk between March 26 and April 13, 2018. Eligible participants completed a baseline survey and 14 daily surveys online. The baseline survey assessed sociodemographics and psychosocial (ie, depression, affect, self-esteem, and stress) factors. Daily surveys assessed substance use and cravings for alcohol and stimulants. Four multivariable random-intercept logistic regression models were built to examine psychosocial constructs separately along with other significant predictors from bivariate analyses while controlling for age and education. RESULTS: Among a total of 272 participants, 220 were White, 201 were male, and 134 were men who have sex with men (MSM). The mean age was 36.1 years (SD 10.5). At baseline, 173 participants engaged in any current or past hazardous alcohol consumption, 31 reported using cocaine, 19 reported using methamphetamine, 8 reported using crack cocaine, and 104 reported any noninjection or injection drug use in the past 6 months. Factors independently associated with substance use were depression (adjusted odds ratio [aOR] 1.11, 95% CI 1.02-1.21; P=.01), negative affect (aOR 1.08, 95% CI 1.01-1.16; P=.01), lower levels of self-esteem (aOR 0.90, 95% CI 0.82-0.98; P=.02), and cravings for alcohol (aOR 1.02, 95% CI 1.01-1.03; P<.001) and stimulants (aOR 1.03, 95% CI 1.01-1.04; P=.01). MSM had higher odds of engaging in substance use in all models (model 1: aOR 4.90, 95% CI 1.28-18.70; P=.02; model 2: aOR 5.47, 95% CI 1.43-20.87; P=.01; model 3: aOR 5.99, 95% CI 1.55-23.13; P=.009; and model 4: aOR 4.94, 95% CI 1.29-18.84; P=.01). CONCLUSIONS: Interventions for substance use should utilize evidenced-based approaches to reduce depression, negative affect, and cravings; increase self-esteem; and engage MSM. Interventions may also consider leveraging technology-based approaches to reduce substance use among populations who use crowdsourcing platforms.

Hepatitis C infections continue to rise among marginalized communities, including among transgender people. Efforts to eliminate hepatitis C from San Francisco require successful identification of active HCV infections among transgender women and subsequent treatment of infection. This secondary analysis of the National HIV Behavioral Surveillance Transgender Women (NHBS-Trans) Study aims to identify areas of improvement in the hepatitis C care cascade and associated barriers that preclude successful treatment. One hundred and eighty (89.6%) trans women reported being previously screened for HCV, 47 (26.1%) reported being diagnosed with HCV, twenty-eight of the 47 (59.6%) who reported HCV diagnosis also reported that they received HCV treatment, with and 24 of the 28 (85.7%) reported completing their treatment. Overall, we detected HCV antibodies among 23.9% of participants and detected HCV RNA among 6.0%. This suggests that despite improvements in screening for HCV, active cases may not be successfully treated. Efforts to reduce barriers to HCV care should be prioritized, with heightened consideration for trans-specific needs.

Men who have sex with men (MSM) have a high prevalence of hazardous alcohol consumption. While network-level characteristics such as social network size have been indicated as upstream determinants of alcohol use in general population samples, no studies have examined factors associated with alcohol using network size (ANS), among MSM.This secondary analysis examined demographic, substance use, and sexual behavior correlates of ANS using data from a diverse sample of alcohol-using MSM in San Francisco (N = 252). Associations were calculated using multivariable negative binomial regression, adjusting for age, race, education, and employment.The median ANS was 10. Factors associated with larger ANS in multivariable analyses included identifying as Hispanic/Latino, having completed a college education or higher, having a higher Alcohol Use Disorders Identification Test (AUDIT) score, having a greater number of sexual partners, polysubstance use, and being unaware of one's own HIV status. Factors associated with smaller ANS included being between 18 and 24 years of age, reporting a low income, and having any lifetime history of injection drug use.For MSM, ANS was associated with increased likelihood of hazardous alcohol use, as well specific individual-level substance use and sexual risk behaviors. These results highlight the role of ANS in hazardous alcohol consumption and sexually transmitted infection transmission among MSM. These results also indicate ways that research and intervention programs aimed at reducing alcohol use among MSM might be improved through network-based recruitment or engagement. Finally, these results suggest the need for further research on HIV-unknown MSM.

Trans women have been understudied in the Hepatitis C virus (HCV) epidemic, yet data suggest they may be at elevated risk of the disease. Using data collected from the Centers for Disease Control and Prevention's (CDC) National HIV Behavioral Surveillance (NHBS) survey, we measured HCV seropositivity, viremia, and associated risk factors for HCV infection among trans women in San Francisco from June 2019 to February 2020. Respondent-driven sampling (RDS) was used to obtain a diverse, community-based sample of 201 trans women, of whom 48 (23.9%, 95% CI 17.9% - 30.0%) were HCV seropositive. HCV seropositivity significantly increased with increasing age (adjusted prevalence ratio [APR] 1.04 per year, 95% CI 1.01-1.07) and history of injection drug use (APR 4.44, 95% CI 2.15-9.18). We also found that many had HCV viremia as twelve (6.0% of the total sample, 95% CI 2.7% - 9.3%) were RNA-positive for HCV. Trans women are highly impacted by HCV and could benefit from access to regular and frequent HCV screening and treatment access. HCV screening could be offered regularly in trans-specific health services, in the community, in jails and prisons, and integrated syringe exchange programs where treatment access or referral are also available.

BACKGROUND: Transgender women (trans women) in Nepal are underserved in the HIV response. Data are needed to determine the HIV prevalence disaggregated from other key populations and to identify the particular risks faced by this community. Trans women are marginalized around the world and research is also needed to determine the impact of stigma on HIV risk to inform trans-specific interventions. METHODS: In 2019, we conducted the first population-based HIV behavioral surveillance study of trans women disaggregated from other key populations using respondent driven sampling (RDS). We estimated the HIV prevalence for trans women, and bivariate and multivariate Poisson binomial regression models were constructed to examine the relationship between HIV risk and stigma. RESULTS: Trans women participants (N = 200) had a mean age of 33 years old (SD = 10.96). We found a weighted HIV prevalence of 11.3% (95% CI 6·82% - 18·13). We found that depression and anxiety (aPR 0.81; 95% CI 0.67-0.97; p = 0·02) and current engagement in sex work (aPR 1.31; 95% CI 1.01-1.71; p = 0·046) were significantly associated with greater prevalence of condomless receptive anal intercourse. We found that experienced stigma of ever being verbally abused due to gender identity was significantly associated with lower prevalence of depression and anxiety (aPR 0.42; 95% CI 0.20-0.87; p = 0·002). Feeling unaccepted in Nepali society and believing people thought they were a criminal because of their trans identity was significantly associated greater prevalence of current sex work (aPR 1.36; 95% CI 1.03-1.78; p = 0·03; aPR 1.45; 95% CI 1.03-2.07; p = 0.04). Every measure of experienced stigma assessed was significantly associated with greater prevalence of current engagement in sex work. CONCLUSIONS: Trans women are highly stigmatized in Nepal, leading to individual and systems factors that impact their risk for HIV. Interventions are needed that support the economic and mental wellbeing of trans women to prevent their heighted risk of HIV from stigma.

Objectives. To examine differences in HIV prevalence and experiences of discrimination within the trans women community in California's San Francisco Bay Area.Methods. Intersectional positions were constructed on the basis of race/ethnicity (non-Hispanic White, non-Hispanic Black, Latina) and gender identity (female identifying, transgender identifying). We used baseline data from the Trans*National study (2016-2017) to construct regression models that estimated racial/ethnic differences in the attribution of discrimination experienced and, along with surrogate measures for intersectionality, estimated risk among those who were dually marginalized (racial/ethnic minority and transgender identifying). Margins plots were used to visually compare absolute risk across all intersectional positions.Results. Black and Latina trans women were more likely to be HIV positive than non-Hispanic White trans women. In several of the study domains, we estimated a lower risk of reporting discrimination among dually marginalized trans women than among White female-identifying trans women.Conclusions. Quantitative intersectionality methods highlight the diversity of experiences within the trans women community and reveal potential measurement challenges. Despite facing multiple forms of systemic marginalization, racial/ethnic minority trans women report less discrimination than White trans women. Subjective reporting of discrimination likely undercounts risks among racial/ethnic minorities.

INTRODUCTION: Marginalization of sex work presents numerous risks for trans women (TW) engaged in the sex trade, including criminalization, traumatization, and contracting HIV. We identified socio-economic and HIV risk disparities among trans women sex workers and others who do sex work (TWSW/OWSW), and evaluated these disparities for TWSW/OWSW compared to TW not engaged in sex work from pre- and post-implementation of the US 2018 "Allow States and Victims to Fight Online Sex Trafficking Act" and "Stop Enabling Sex Traffickers Act" (FOSTA-SESTA). METHODS: We analyzed 429 trans women (TW) from the Trans*National cohort study (2016-2019). Generalized estimating equations (GEE) characterized differences in socio-economic and HIV risk outcomes for TWSW/OWSW compared to TW not engaged in sex work over the study period. Adjusted, pre-to-post law changes in these outcomes for TWSW/OWSW versus TW not engaged in sex work were compared using difference-in-differences GEE regression analyses. RESULTS: Over 18 months, TWSW/OWSW had higher adjusted odds of being unstably housed, having income from criminalized sources, experiencing transphobic hate crimes, experiencing discrimination from police/courts, being incarcerated, meeting sex partners in the street/public settings, meeting sex partners on Craigslist or other online forums (except dating apps), or engaging in condomless anal intercourse, (p < 0.01 for all comparisons); TWSW/OWSW also had a higher mean number of income sources (p = 0.03). One difference-in-differences analysis showed additive interaction: the adjusted mean number of income sources reported by TWSW/OWSW compared to those not engaged in sex work decreased from pre-to post-FOSTA-SESTA (from 1.79 to 1.48 for TWSW/OWSW and from 1.52 to 1.47 for TW not engaged in sex work; p = 0.01). CONCLUSIONS: Disparities in socio-economic and HIV-related risk outcomes exist for TWSW/OWSW in San Francisco. There is an urgent need for comprehensive, long-term follow-up data of TW to accurately analyze policy effects, especially given the recent enactment of a number of other policies targeting TW.
