Assessing the Risk of Sexually Transmitted Infections among Men who have Sex with Men in San Francisco during COVID-19: A Socio-ecological Analysis.

Background: Men who have sex with men (MSM) are disproportionately affected by sexually transmitted infections, a disparity that has only worsened in recent years. During the COVID-19 pandemic, an overall increasing trend remained.

Methods: We utilized data from the MSM cycle of the National HIV Behavioral Surveillance (NHBS) study in San Francisco, California, conducted from June 2021 through December 2021, to identify socio-ecological disruptions during the COVID-19 pandemic that were associated with sexually transmitted infections.

High interest for long-acting injectable PrEP among men who have sex with men at most risk for HIV in San Francisco, 2021.

Background Men who have sex with men (MSM) represent a disproportionate total of incident HIV cases. Oral pre-exposure prophylaxis (PrEP) has contributed to significant declines in total HIV incidence. Barriers to PrEP include individual and structural factors that can prevent PrEP adherence and persistence.

Sample composition and HIV prevention indicator differences using physical vs. virtual venue recruitment of men who have sex with men in San Francisco.

During the COVID-19 pandemic, the sampling method for the National HIV Behavioral Surveillance (NHBS) in San Francisco changed from physical venue time-location sampling (TLS) to online or virtual venue TLS for men who have sex with men (MSM). We present differences in the samples of MSM recruited using physical venue TLS in 2017 and virtual venue TLS in 2021. We further assess changes in preventive and risk behaviors from 2017 to 2021 after controlling for differences in the sample compositions with multivariable Poisson models using GLM with robust standard errors.

HIV and hepatitis C virus infection and co-infection among trans women in San Francisco, 2020.

Background: Transgender women (hereafter "trans women") face social marginalization, stigma, and discrimination and experience a high burden of HIV. More recently, trans women have been identified as having a high risk for hepatitis C (HCV) infection. The interaction between these two diseases and the risks for HIV/HCV co-infection among trans women are understudied.

Structural disadvantage and HIV risk - comparing risk factors between trans women's partnerships with cis men and trans women sexual partners.

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.

Detectable viral load associated with unmet mental health and substance use needs among trans women living with HIV in San Francisco, California.

Background: Substance use and mental distress are known barriers to HIV care engagement among trans women. Less is known about access and utilization of mental health and substance use care among trans women and the relationship between unmet behavioral health needs and HIV viral suppression. We examined the relationship between mental health and substance use on HIV viral load among trans women living with HIV.

The association between religiosity and resilience among young trans women.

Introduction: Young transgender women (trans women) experience poor health in part due to discrimination. Factors that promote resilience may help young trans women positively adapt to discrimination, resulting in attenuation of poor health outcomes. While religion is sometimes a source of stigma and transphobia, qualitative studies have identified religiosity as an important resilience resource for young trans women.

Through a Different Lens: Occupational Health of Sex-Working Young Trans Women.

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 (=263, San Francisco).

Results: Overall, 41.

Stigma as a barrier and sex work as a protective factor for HIV testing among trans women in Nepal.

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.

Disparities in Sexually Transmitted Infection Testing and the Need to Strengthen Comprehensive Sexual Health Services for Trans Women.

Purpose: Few studies have examined the importance of improving the sexual health delivery system beyond HIV among trans women. We assessed survey data from the National HIV Behavioral Surveillance Transgender Woman (NHBS-Trans) Study in San Francisco to characterize the utilization of sexual health services among HIV-negative trans women and to explore opportunities to improve sexual health services for trans women.

Methods: Trans women were recruited through respondent-driven sampling from July 2019 to February 2020.

The Dose Response Effects of Digital HIV Care Navigation on Mental Health and Viral Suppression Among Young People Living With HIV: Single-Arm, Prospective Study With a Pre-Post Design.

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.

HIV prevalence, engagement in care, and risk behavior among trans women, San Francisco: Evidence of recent successes and remaining challenges.

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.

Prevalence and Correlates of Violence Experienced by Trans Women.

To measure the prevalence and correlates of intimate partner, physical, and sexual violence experienced by trans women. A National HIV Behavioral Surveillance (NHBS) Study of 201 trans women was conducted in San Francisco from July 2019 to February 2020 using respondent-driven sampling. Prevalence ratio tests were used to test differences in the prevalence of violence by demographic characteristics including housing status.

A global cautionary tale: discrimination and violence against trans women worsen despite investments in public resources and improvements in health insurance access and utilization of health care.

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.

In Their Own Words: How Trans Women Acquired HIV Infection.

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.

A Technology-Based Intervention Among Young Men Who Have Sex With Men and Nonbinary People (The Conectad@s Project): Protocol for A Vanguard Mixed Methods Study.

Background: In many parts of the world, including Brazil, uptake for biomedical interventions has been insufficient to reverse the HIV epidemic among key populations at high risk for HIV, including men who have sex with men. Young MSM (YMSM), particularly Black YMSM, have high HIV incidence, low viral suppression, and low preexposure prophylaxis (PrEP) uptake and adherence. Therefore, novel approaches to increase the HIV biomedical interventions uptake by YMSM are urgently needed.

Expanding the Pie-Differentiated PrEP Delivery Models to Improve PrEP Uptake in the San Francisco Bay Area.

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.

Improved PrEP Awareness and Use among Trans Women in San Francisco, California.

Transgender women face a serious risk of HIV infection. Despite this, there is limited knowledge and use of Pre-exposure prophylaxis (PrEP). We measured the continuity of prevention across services in the PrEP cascade and correlates of PrEP use among trans women in San Francisco enrolled in the 2019/20 National HIV Behavioral Surveillance Study.

Experiences and factors associated with transphobic hate crimes among transgender women in the San Francisco Bay Area: comparisons across race.

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.

Population-based HIV prevalence, stigma and HIV risk among trans women in Nepal.

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.

Disparities in HIV-related risk and socio-economic outcomes among trans women in the sex trade and effects of a targeted, anti-sex-trafficking policy.

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).

Intercategorical and Intracategorical Experiences of Discrimination and HIV Prevalence Among Transgender Women in San Francisco, CA: A Quantitative Intersectionality Analysis.

To examine differences in HIV prevalence and experiences of discrimination within the trans women community in California's San Francisco Bay Area. 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).

Prevalence and Correlates of Nonprescription Hormone Use Among Trans Women in São Paulo, Brazil.

The purpose of this study was to determine the prevalence and correlates of nonprescription hormone use among Brazilian trans women. This study is a cross-sectional survey of trans women in São Paulo, Brazil, recruited by respondent-driven sampling in 2017-2019. Of 790 trans women, 36.
