The PrEP cascade in a sample of HIV-negative or unknown status adolescent and young adult transgender women in Peru.

Background: Transgender women are a key population in the HIV epidemic globally, including in Peru. This cross-sectional epidemiological study characterized the pre-exposure prophylaxis (PrEP) cascade in adolescent and young adult transgender women in Peru to inform roll-out of early HIV prevention efforts.

Methods: Between February-July 2022, a community-recruited sample of HIV-negative or status unknown young transgender women ( = 140) in Peru completed a socio-behavioral survey and biological testing for HIV and bacterial STIs.

The "Cycle" of HIV: Limits of Personal Responsibility in HIV Vulnerability Among Transgender Adolescents and Young Women in Lima, Peru.

Globally, transgender women (TW) face a high burden of the HIV epidemic. In Peru, HIV prevalence among TW rises at age 25, indicating a need to understand HIV vulnerability as adolescents reach adulthood. The life course of TW is often marked by abuse, discrimination and poverty fueled by transphobic stigma.

Social, economic, and physical side effects impact PrEP uptake and persistence among transgender women in Peru.

Introduction: Oral pre-exposure prophylaxis (PrEP) for HIV-1 infection is over 99% effective in protecting against HIV acquisition when used consistently and appropriately. However, PrEP uptake and persistent use remains suboptimal, with a substantial gap in utilization among key populations who could most benefit from PrEP. In Latin America specifically, there is poor understanding of barriers to PrEP uptake and persistence among transgender (trans) women.

HIV vulnerabilities and psychosocial health among young transgender women in Lima, Peru: results from a bio-behavioural survey.

Introduction: Peruvian young transgender women (YTW) ages 16-24 years are a critical but understudied group for primary HIV prevention efforts, due to sharp increases in HIV prevalence among TW ages 25 years and older.

Methods: Between February and July 2022, a cross-sectional quantitative study with YTW ages 16-24 years in Peru (N = 211) was conducted consisting of a bio-behavioural survey accompanied by laboratory-based testing for HIV and sexually transmitted infections (STIs). Bivariate and multivariable Poisson regression models were used to estimate prevalence ratios between socio-demographic and behavioural characteristics and HIV status.

Both/And: Mixed methods analysis of network composition, communication patterns, and socio-economic support within social networks of transgender women involved in sex work in Lima, Peru.

Introduction: Social networks contribute to normative reinforcement of HIV prevention strategies, knowledge sharing, and social capital, but little research has characterized the social networks of transgender women (TW) in Latin America. We conducted a mixed methods analysis of three network clusters of TW in Lima, Peru, to evaluate network composition, types of support exchanged, and patterns of communication.

Methods: We recruited TW residing in or affiliated with three "casas trans" (houses shared among TW) in Lima between April-May 2018.

Social Networks Play a Complex Role in HIV Prevention Knowledge, Attitudes, Practices, and the Uptake of PrEP Through Transgender Women Communities Centered Around Three "Casas Trans" in Lima, Peru: A Qualitative Study.

Transgender women's (TW) social networks may facilitate HIV prevention information dissemination and normative reinforcement. We conducted a qualitative study of social networks among 20 TW affiliated with 3 "casas trans" (houses shared among TW) in Lima, Peru, using diffusion of innovations theory to investigate community-level HIV prevention norms. Participants completed demographic questionnaires, social network interviews, and semistructured in-depth interviews.

A Cross-Sectional Analysis of Self-Reported Needs and Health Service Utilization Among Transgender Women in Lima, Perú.

Globally, transgender women (TGW) experience wide-ranging barriers to health and care, with disproportionately high risks of infectious and chronic diseases. Yet, research on transgender populations' access to care in low- and middle-income countries remains limited, focused on human immunodeficiency virus (HIV) infection, and assesses TGW as a homogenous group. We analyzed morbidity and health service uptake patterns among TGW in Lima, Perú, to understand health outreach and service needs to inform targeting and design of community-level interventions.

Brief Report: Self-Reported Knowledge of HIV Status Among Cisgender Male Sex Partners of Transgender Women in Lima, Peru.

Background: Knowledge of HIV status is a critical first step in the HIV care cascade. Cisgender male sex partners of transgender women (MSTW) are at a disproportionately high risk of HIV, but little is known about their access to HIV testing or knowledge of HIV status.

Methods: We used cross-sectional data from a respondent-driven sampling study to analyze self-reported HIV status and predictors of knowledge of HIV status among MSTW in Lima, Peru.

Self-Identity, Beliefs, and Behavior Among Men Who Have Sex with Transgender Women: Implications for HIV Research and Interventions.

While transgender women have been identified as a global priority population for HIV prevention and treatment, little is known about the cisgender male partners of transgender women, including their sexual behavior and HIV prevalence. Previous research has suggested that these male partners have varied identities and sexual behavior, which make identifying and engaging them in research difficult. This paper describes interviews conducted with fifteen cisgender men who reported recent sexual activity with transgender women in Lima, Peru.

The wisdom of mistrust: qualitative insights from transgender women who participated in PrEP research in Lima, Peru.

Introduction: Although pre-exposure prophylaxis (PrEP) is a remarkable biomedical advance to prevent HIV, ongoing research on PrEP contributes to and interacts with a legacy of HIV experimentation on marginalized communities in resource-limited settings. This paper explores the complexity of PrEP research mistrust among Peruvian transgender (trans) women who completed a PrEP adherence intervention and those who refused participation (i.e.

Decision-Making at the Intersection of Risk and Pleasure: A Qualitative Inquiry with Trans Women Engaged in Sex Work in Lima, Peru.

To inform culturally relevant HIV prevention interventions, we explore the complexity of sex work among Peruvian transgender women. In 2015, we conducted twenty in-depth interviews and demographic surveys with transgender women in Lima, Peru to examine how transgender women enact individual- and community-level resistance strategies within a context of pervasive marginalization. Although 40% self-identified as "sex workers," 70% recently exchanged sex for money.

Exploring HIV risk behavior and sexual/gender identities among transgender women and their sexual partners in Peru using respondent-driven sampling.

HIV prevalence is high among transgender women, but little is known about cisgender men who have sex with transgender women (MSTW). The objective of this study was to investigate characteristics and behavior of MSTW compared to transgender women and men who have sex with men (MSM) using a modified respondent-driven sampling design. Seed participants completed a survey and invited up to three sex partners.

TransPrEP: Results from the Pilot Study of a Social Network-Based Intervention to Support PrEP Adherence Among Transgender Women in Lima, Peru.

We conducted a pilot randomized controlled trial of a social network-based intervention to promote PrEP adherence among transgender women (TW) in Lima, Peru. We enrolled 89 TW from six social networks and cluster-randomized them 1:1 to standard of care (n = 44) or the TransPrEP intervention (n = 45). Core workshops discussed strategies to support PrEP adherence and defined group adherence objectives.

Intimate Partner Violence Against Transgender Women: Prevalence and Correlates in Lima, Peru (2016-2018).

Limited data exists on intimate partner violence (IPV) among transgender women (TW), though global trends suggest IPV is associated with HIV risk in this population. We describe the prevalence of verbal, physical, and/or sexual violence as well as participant- and partner-level correlates of IPV among TW in Lima, Peru. Among 389 respondents, 15.

Integration of Gender-Affirming Primary Care and Peer Navigation With HIV Prevention and Treatment Services to Improve the Health of Transgender Women: Protocol for a Prospective Longitudinal Cohort Study.

Background: Public health strategies are urgently needed to improve HIV disparities among transgender women, including holistic intervention approaches that address those health needs prioritized by the community. Hormone therapy is the primary method by which many transgender women medically achieve gender affirmation. Peer navigation has been shown to be effective to engage and retain underserved populations living with HIV in stable primary medical care.

Perceived Barriers and Facilitators to Integrating HIV Prevention and Treatment with Cross-Sex Hormone Therapy for Transgender Women in Lima, Peru.

Transgender women (TW) represent a vulnerable population at increased risk for HIV infection in Peru. A mixed-methods study with 48 TW and 19 healthcare professionals was conducted between January and February 2015 to explore barriers and facilitators to implementing a model of care that integrates HIV services with gender-affirmative medical care (i.e.

Leveraging social capital: multilevel stigma, associated HIV vulnerabilities, and social resilience strategies among transgender women in Lima, Peru.

Introduction: In Peru, transgender women (TW) experience unique vulnerabilities for HIV infection due to factors that limit access to, and quality of, HIV prevention, treatment and care services. Yet, despite recent advances in understanding factors associated with HIV vulnerability among TW globally, limited scholarship has examined how Peruvian TW cope with this reality and how existing community-level resilience strategies are enacted despite pervasive social and economic exclusion facing the community. Addressing this need, our study applies the understanding of social capital as a social determinant of health and examines its relationship to HIV vulnerabilities to TW in Peru.
