Navigating sexual and reproductive health among Venezuelan women sex workers in Peru
Migration to Peru from Venezuela has reshaped engagement in informal labour for many women who turn to sex work as a survival strategy amid legal precarity and systemic exclusion. Yet little is known about how migrant sex workers navigate sexual and reproductive health (SRH) in this context. In 2023, we conducted 34 semi-structured interviews with Venezuelan migrant cisgender women sex workers living in Lima, Peru. Interviews explored migration t…
Transgender stigma
This study analyzes the discursive construction of transgender stigma in depictions of transgender people by the Peruvian press. It provides an important theoretical advancement establishing the press’ disapproving language actions (DLAs) as the nexus between social control and stigma. It connects sociolinguistics, speech act theory, media studies, and transgender research, leveraging the value of prior research informing the speech action of dis…
Estamos Aqui (We Are Here)
Deficit-based public narratives about migrants can be profoundly violent, (re)producing intersectional stigma and exacerbating harm for gay and bisexual migrant sex workers. Migration in Latin America has doubled since 1990, with millions of Venezuelan migrants resettling in neighboring countries like Colombia, where rising xenophobia is fueled by negative portrayals in media, research, and public discourse. Guided by the theoretical movement of …
“We live at the crossroads”
Post-migration sexual health and pleasure among gay and bisexual venezuelan migrant men in Lima, Peru
This paper explores how migration (re)shapes the sexual lives of gay, bisexual, and other men who have sex with men (GBM) from Venezuela now living in Lima, Peru. While global public health discourses have predominantly framed GBM migrant sexualities through narratives of risk, especially in relation to HIV, this study draws attention to the dynamic interplay between pleasure and vulnerability in post-migration sexuality. Based on five focus grou…
Design and pilot evaluation of a brief intervention to reduce transphobia and improve attitudes of government officials to address legal gender affirmation needs of transgender people in Peru
Legal gender affirmation – legal name and gender marker change – is an important health-promoting health determinant for transgender people. In Peru, the state's failure to universally recognize transgender people’s legal identity limits standardized legal affirmation procedures, including the paucity of government officials trained in gender affirmation strategies. This project, in partnership with Registro Nacional de Identificación y Estado Ci…
The “Cycle” of HIV
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. Approaches to the HIV epidemic among TW and adolescents emphasize problem behaviors such as unprotected sex and substance. However, there ha…
Covid-19 violence and the re-making of urban space through solidarity networks among transgender women in Lima, Peru
A Rapid Ethnography to Inform a Biobehavioural HIV Preventions Study Among Venezuelan Migrant Sex Workers in Peru
The Venezuelan refugee crisis has triggered Latin America's largest mass migration, displacing over a fifth of the country's population. A significant number of migrants have sought refuge in neighboring countries like Peru. Within this context, Venezuelan migrants confront an array of vulnerabilities, including xenophobia and economic hardship, which have compelled some to sex work for their livelihoods. Venezuelan sex workers (VSWs) in Peru fac…
Contributing factors for self-reported HIV in male Peruvian inmates
Introduction: Worldwide, prisons are high-risk settings for the transmission of infectious diseases such as HIV. There is a need to understand the health conditions of prisoners to improve and implement timely strategies for HIV diagnosis and control. Hence, we aimed to identify factors associated with self-reported HIV (srHIV) among Peruvian inmates. Methods: This study is a secondary data analysis of the First Peruvian Prison Census conducted i…
Covid-19 vaccine equity and the right to health for displaced Venezuelans in Latin America
Given the magnitude of Venezuelan displacement in Latin America, there is a need to assess how migrants were, and will continue to be, addressed in COVID-19 vaccination policies. To explore migration status as a dimension of vaccine equity in Latin America and in relation to international human rights, we assessed national vaccination plans, peer-reviewed, and gray literature published between January 2020 and June 2021. Three key rights-related …
Intersectional stigma and the arc of intranational migration
Findings advance understandings of intranational migration and forced displacement as key determinants of trans women's health. Dimensions of violence at the intersection of classism and cisgenderism render trans women highly vulnerable at every step of their migratory journeys. Experiences of intranational mobility and relocation were described as uniquely tied to age, intersectional transphobic stigma, engagement in sex work, and multiple forms…
Exploring Contextual Differences for Sexual Role Strain Among Transgender Women and Men Who Have Sex with Men in Lima, Peru
Perceived Barriers and Facilitators to Integrating HIV Prevention and Treatment with Cross-Sex Hormone Therapy for Transgender Women in Lima, Peru
Partner-Level Factors Associated with Insertive and Receptive Condomless Anal Intercourse Among Transgender Women in Lima, Peru
HIV Status Communication with Sex Partners and Associated Factors Among High-Risk MSM and Transgender Women in Lima, Peru
Mind the gap
Sampling strategies such as respondent-driven sampling (RDS) and time-location sampling (TLS) offer unique opportunities to access key populations such as men who have sex with men (MSM) and transgender women. Limited work has assessed implementation challenges of these methods. Overcoming implementation challenges can improve research quality and increase uptake of HIV services among key populations. Drawing from studies using RDS in Brazil and …
HIV risk and preventive interventions in transgender women sex workers
Determinants of unequal HIV care access among people living with HIV in Peru
BACKGROUND: Equity in access to health care among people living with HIV (PLHA) has not been extensively studied in Peru despite the fact there is significant social diversity within this group. We aimed to assess the extent to which health care provision to PLHA, including ARVT, was equitable and, if appropriate, identify factors associated with lower access. METHODS: We conducted a survey among adult PLHA in four cities in Peru, recruited throu…
