RESUMEN

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. RESULTS: HIV prevalence was 41.5% (95% CI: 33.9-49.4%), recent syphilis acquisition 19.4% (95% CI: 12.7-28.4), chlamydia 6.3% (95% CI: 3.1-11.1) and gonorrhoea 12.3% (95% CI: 7.9-18.7). Almost half (47.9%) reported condomless anal sex in the past 6 months, 50.7% reported sex work in the past 30 days and 13.7% reported accepting more money for condomless sex. There were no significant differences in reported sexual behaviours by HIV status. Only 60.8% of participants reported ever having been tested for HIV, and 25.6% reported a past 6-month STI test. More than two-thirds (67.8%) had not heard of antiretroviral pre-exposure prophylaxis (PrEP) and only 4.7% had taken PrEP in the past month. Current moderate-to-severe psychological distress was endorsed by 20.3%, 10.0% reported attempting suicide in the past 6 months and 85.4% reported alcohol misuse. CONCLUSIONS: Findings show that the HIV epidemic for YTW in Lima, Peru is situated in the context of widespread social exclusion, including economic vulnerabilities, violence victimization and the mental health sequelae of transphobic stigma that starts early in life. Future research should aim to further understand the intersection of these vulnerabilities. Moreover, there is an urgent necessity to design and evaluate HIV prevention programmes that address the root systems driving HIV vulnerabilities in YTW and that focus on developmentally specific clusters of stigma-related conditions.

RESUMEN

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 Civil (RENIEC) and transgender communities, designed and piloted a group-based intervention to sensitize government officers to the importance of gender-concordant identity documents. Between August 2017 and February 2018, three in-person group intervention sessions were held (each 3-4 hours) with 51 government officers. Guided by Gender Affirmation and Structural Violence Frameworks, the intervention utilized Adult Learning Theory and applied storytelling and testimonials as pedagogy. Pre-/post-test surveys were administered (19 true/false items, summed to create an index score measuring knowledge and attitudes toward transgender people). Within-person changes in pre-/post-intervention scores were evaluated using paired t-tests. Pre-/post-test data were available for 41 participants. After the intervention, there were improvements in knowledge and more favorable attitudes toward transgender people (pre-test mean = 14.09, SD = 2.33 vs. post-test mean = 15.62, SD = 1.82; difference = 1.53, 95% CL = 0.60, 2.67; t-test = 3.30 [df = 46]; p = 0.002). The intervention was feasible to conduct and garnered high acceptability. The results suggest the promise of this brief intervention for future research and testing before potential later implementation and scale-up to increase the capacity of government officers to address legal gender affirmation for transgender people in Peru.


Main findings: A brief group-based theoretically informed intervention designed and piloted by a multidisciplinary cross-sector team in partnership with transgender communities was feasible to conduct, garnered high levels of acceptability, and significantly increased knowledge and favorable attitudes toward transgender people for government officers responsible for identity documents in Peru.Added knowledge: Legal gender affirmation is an important determinant of mental health and wellbeing for transgender people; this evidence-based intervention increased the capacity of government officers to meet health-harming legal gender affirmation needs, specifically legal name and gender marker change, addressing a structural barrier to legal gender affirmation for transgender people in Peru.Global health impact for policy and action: Findings underscore the promise of this intervention for future research and testing before potential later implementation and scale-up in Peru, and for adaptation in other countries and contexts to address the training and capacity of government officials to effectively process and implement legal gender affirmation, a structural barrier to legal gender affirmation for transgender people.

RESUMEN

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 in 2016. We estimated the prevalence of srHIV in prisoners who were male at birth and the association of srHIV with other social conditions, criminal records, and prevalent health conditions. Nested models identified a multivariable parsimonious model for factors associated with srHIV and yielding prevalence ratios adjusted by the included parameters. Results: The census surveyed 71,087 male inmates of whom 0.4% reported srHIV (n = 305), and 82% of whom were receiving antiretroviral treatment (n = 220). In our final multivariable model, srHIV was independently associated with age between 36 and 55 years old vs. >55 years old [parsimonious prevalence ratio (pPR) = 1.98, 95% CI, 0.96-4.08], having a stable partner out of prison (pPR = 1.64, 95% CI, 1.24-2.19), being homosexual (pPR = 4.16, 95% CI, 2.50-6.90), self-report of prevalent tuberculosis co-infection (pPR = 2.55, 95% CI, 1.82-3.58), self-report of prevalent sexually transmitted infections (pPR = 34.49, 95% CI, 24.94-47.70), and self-report of prevalent illicit drug use 30 days before the survey (pPR = 1.91, 95% CI, 1.43-2.56). Conclusion: Self-reported HIV is associated with multiple social, health and prison risks among Peruvian inmates. Deeply understanding these factors would help to design HIV prevention and control strategies in Peruvian prisons.

RESUMEN

BACKGROUND: Globally transgender women (TW) are at heightened vulnerability for HIV infection. In Lima Peru, sharp increases in HIV prevalence are seen among TW ages 25 years and older highlighting the need for early HIV prevention efforts for young TW. This study conducted in-depth qualitative interviews to elucidate the social and developmental contexts of HIV vulnerability for young TW in Lima Peru. METHODS: Between November 2019 and February 2020, young TW ages 16-24 years (n = 21) in Lima Peru were purposively sampled using in-person (e.g., face-to-face outreach) and online (e.g., social media, networking websites) social network-based methods. Interviews were conducted in Spanish and a rapid qualitative analysis was conducted using a modified immersion crystallization methodology to identify themes. RESULTS: Five themes emerged, informing the conceptualization of a Life Course Health Development Model of HIV Vulnerabilities and Resiliencies: (1) interpersonal contexts (family, school, partners, sexual debut, trans mothers); (2) structural vulnerabilities (poverty, educational constraints, migration, hostile environments, sex work, police violence); (3) concomitant mental health and psychosocial factors (discrimination, violence, depression, suicidality, substance use, life hopes/dreams/future expectations); (4) gender affirmation processes (gender identity development, hormones, surgery, legal name/gender marker change); (5) HIV prevention and treatment barriers (PrEP uptake, HIV care, condom use, risk reduction). CONCLUSIONS: Young TW experience formidable developmental challenges associated with transphobia, violence, and pre-maturely facing accelerated milestones. Developmentally and culturally appropriate interventions to mitigate HIV vulnerability in Peru are needed, including those that consider co-occurring stigma-related conditions in adolescence and young adulthood.

RESUMEN

BACKGROUND: Migration is recognized as a key determinant of health. Yet, limited research addresses the arc of intranational migration and, even less, the experiences of transgender (trans) adolescents and women migrants and the associated health vulnerabilities. Using intersectional stigma as a theoretical frame, this study seeks to better understand the sexual health vulnerabilities and needs of trans women migrants in Peru. METHODS: Between October and November 2016, in-depth interviews (n = 14) and two focus groups (n = 20) were conducted in Spanish with trans women in three Peruvian cities. To explore pre- and during migration experiences, focus groups were conducted in Pucallpa and Iquitos, key cities in the Amazon where trajectories often originate. To assess during migration and post-migration experiences, we conducted interviews in Pucallpa, Iquitos, and Lima to better understand processes of relocation. Audio files were transcribed verbatim and analysed via an immersion crystallization approach, an inductive and iterative process, using Dedoose (v.6.1.18). RESULTS: Participants described migration as an arc and, thus, results are presented in three phases: pre-migration; during migration; and post-migration. Intersectional stigma was identified as a transversal theme throughout the three stages of migration. The pre-migration stage was characterized by poverty, transphobia, and violence frequently motivating the decision to migrate to a larger city. Exploitation was also described as pervasive during migration and in relocation. Many participants spoke of their introduction to sex work during migration, as key to economic earning and associated violence (police, clients). CONCLUSION: 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 of violence, which impact and can magnify sexual health vulnerabilities for transgender women in Peru who migrated intranationally.

RESUMEN

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 concerns were found to restrict the health rights of migrants in the region: 1) lack of prioritization of migrants in vaccine distribution; 2) onerous documentation requirements to be eligible for COVID-19 vaccination; and (3) how pervasive anti-migrant discrimination limited equitable health care access. While international human rights law prohibits against discrimination based on migration status, few countries analyzed realized their obligations to provide equal access to COVID-19 vaccines to non-citizens, including displaced Venezuelans. Especially for migrants and displaced people, effective and sustainable vaccination strategies for COVID-19 and future pandemics in Latin America must be guided not only by epidemiological risk but also seek to align with human rights obligations. To achieve this, States must also take special measures to facilitate vaccine access for communities facing systemic discrimination, exclusion, and marginalization.

RESUMEN

Sexual and gender politics inform relational expectations surrounding sexual experiences of Peruvian transgender women (TW) and men who have sex with men (MSM). We used the framework of sexual role strain, or incongruence between preferred sexual role and actual sexual practices, to explore potential conflicts between personally articulated identities and externally defined norms of gender and sexuality and its potential to increase HIV/STI risk. Cross-sectional individual- and dyad-level data from 766 TW and MSM in Lima, Peru were used to assess the partnership contexts within which insertive anal intercourse was practiced despite receptive role preference (receptive role strain), and receptive anal intercourse practiced despite insertive role preference (insertive role strain). Sexual role strain for TW was more common with non-primary partners, while for MSM it occurred more frequently in the context of a primary partnership. Receptive role strain was more prevalent for TW with unknown HIV status (reference: without HIV) or pre-sex drug use (reference: no pre-sex drug use). For homosexual MSM, receptive role strain was more prevalent during condomless anal intercourse (reference: condom-protected) and with receptive or versatile partners (reference: insertive). Among heterosexual or bisexual MSM, insertive role strain was more prevalent with insertive or versatile partners (reference: receptive), and less prevalent with casual partners (reference: primary). Our findings suggest TW and MSM experience different vulnerabilities during sexual role negotiation with different partner-types. Future studies should explore the impact of sexual role strain on condom use agency, HIV/STI risk, and discordances between public and private presentations of gender and sexual orientation.

RESUMEN

In February 2021, the Peruvian 'vaccinegate' scandal broke when the media reported that nearly 500 experimental doses of an ongoing COVID-19 trial were given to key individuals not enrolled in the trial. Indeed, vaccine doses were administered to leading politicians, such as the former President and his wife, and other high-level health officials and academic leaders at the universities overseeing ethical compliance and administration of the trial. The 'vaccinegate' scandal in Peru is but one example of how the lack of a coordinated global response to COVID-19 has allowed countries to act in the best interest of some, ultimately, failing to secure a democratic approach to the right to health for all during a global pandemic. While Peruvian vaccinegate is an example of the egregious use of power to further cronyism amid fear and mounting COVID-19 related death, unfortunately, it is not an anomaly. We argue that the sensationalisation of the event has distracted from the existing precarious health system in Peru and the ways in which long-existing abuses of power evident prior to the pandemic limit a just response to it.

RESUMEN

INTRODUCTION: The entangled health and economic crises fueled by COVID-19 have exacerbated the challenges facing Venezuelan migrants. There are more than 5.6 million Venezuelan migrants globally and almost 80% reside throughout Latin America. Given the growing number of Venezuelan migrants and COVID-19 vulnerability, this rapid scoping review examined how Venezuelan migrants are considered in Latin American COVID-19 vaccination strategies. MATERIAL AND METHODS: We conducted a three-phased rapid scoping review of documents published until June 18, 2021: Peer-reviewed literature search yielded 142 results and 13 articles included in analysis; Gray literature screen resulted in 68 publications for full-text review and 37 were included; and official Ministry of Health policies in Argentina, Brazil, Chile, Colombia, Ecuador, and Peru were reviewed. Guided by Latin American Social Medicine (LASM) approach, our analysis situates national COVID-19 vaccination policies within broader understandings of health and disease as affected by social and political conditions. RESULTS: Results revealed a heterogeneous and shifting policy landscape amid the COVID-19 pandemic which strongly juxtaposed calls to action evidenced in literature. Factors limiting COVID-19 vaccine access included: tensions around terminologies; ambiguous national and regional vaccine policies; and pervasive stigmatization of migrants. CONCLUSIONS: Findings presented underscore the extreme complexity and associated variability of providing access to COVID-19 vaccines for Venezuelan migrants across Latin America. By querying the timely question of how migrants and specifically Venezuelan migrants access vaccinations findings contribute to efforts to both more equitably respond to COVID-19 and prepare for future pandemics in the context of displaced populations. These are intersectional and evolving crises and attention must also be drawn to the magnitude of Venezuelan mass migration and the devastating impact of COVID-19 in the region. Integration of Venezuelan migrants into Latin American vaccination strategies is not only a matter of social justice, but also a pragmatic public health strategy necessary to stop COVID-19.

RESUMEN

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. declined to enrol, voluntarily withdrew, and/or were lost to follow-up). METHODS: Data were derived from 86 trans women (mean age 29 years) participants in the formative (four focus groups (n = 32), 20 interviews) and the evaluation stages (34 interviews) of a social network-based PrEP intervention for trans women in Lima, Peru. The formative stage took place from May to July 2015, while the evaluative stage took place from April to May 2018. Audio files were transcribed verbatim and analysed via an immersion crystallization approach using Dedoose (v.6.1.18). RESULTS: Three paradoxes of trans women's participation in PrEP science as a "key" population emerged as amplifying mistrust: (1) increases in PrEP research targeting trans women but limited perceived improvements in HIV outcomes; (2) routine dismissal by research physicians and staff of PrEP-related side effects and the social realities of taking PrEP, resulting in questions about who PrEP research is really for and (3) persistent limitations on PrEP access for trans women despite increasing involvement in clinical trials, fostering feelings of being a "guinea pig" to advance PrEP science. CONCLUSIONS: Findings highlight the wisdom inherent in PrEP mistrust as a reflection of trans women's experiences that underscore the broken bonds of trust between communities, researchers and the research enterprise. PrEP mistrust is amplified through perceived paradoxes that suggest to trans women that they are key experimental participants but not target PrEP users outside of research settings. Findings highlight the urgent need to reframe mistrust not as a characteristic of trans women to be addressed through education and outreach, but as a systemic institutional- and industry-level problem replicated, manifested and ultimately to be corrected, through global HIV science.

RESUMEN

BACKGROUND: The health of transgender men (trans men)-individuals who identify as men and were assigned a female sex assigned at birth-is overlooked globally. This mixed-methods exploratory study sought to understand the lived experiences, health, and social needs of trans men in Lima, Peru to bring visibility to specific health needs and inform responsive and holistic public health efforts. METHODS: Between July 2016-January 2017, 46 trans men in Lima, Peru participated in a mixed-methods study. Four focus group discussions were conducted, complemented with 10 one-on-one interviews to explore in-depth issues that arose in groups. Two individuals participated in both a focus group and an interview. All participants completed a brief survey assessing sociodemographic characteristics and experiences with healthcare, mental health, and stigma. Audio files were transcribed verbatim and analyzed using an immersion crystallization approach to identify themes. RESULTS: Participants had a mean age of 24 years (range 18-48). Trans men reported a lack of awareness and information among medical providers, avoidance of healthcare due to discrimination and maltreatment, an absence of public services for medical gender affirmation (hormones, surgeries), and unmet mental health needs. Trans men described health as multidimensional and influenced by social, economic, and legal contexts including family, school, employment and work, legal identity recognition, discrimination in public spaces, and peer support. Violence, stigma, and intersecting forms of oppression were described as limiting social and legal recognition of trans identity a central dimension of health. Peer support, often in an online environment, was described as important to resistance and well-being. CONCLUSIONS: Findings demonstrate that the physical and mental health of trans men, as well as unmet needs for healthcare services, are influenced by a complex set of social, economic, and legal challenges due to the social exclusion of trans people in Peruvian society. Results are a call to action for stakeholders in Peru to guarantee the rights, health, and wellbeing of this community.

RESUMEN

INTRODUCTION: Among men who have sex with men (MSM) and transgender women (TW), stimulant use is high and has been associated with an increased risk of HIV infection, suicide and cardiovascular disease (CVD) mortality. We used epidemic modelling to investigate these intersecting health harms among MSM/TW in Lima, Peru and assess whether they could be mitigated by prioritizing HIV pre-exposure prophylaxis (PrEP) and harm reduction interventions among MSM/TW who use stimulants. METHODS: We adapted a dynamic model of HIV transmission among MSM/TW in Lima to incorporate stimulant use and increased HIV risk, suicide and CVD mortality. Among 6% to 24% of MSM/TW using stimulants (mostly cocaine), we modelled an increased risk of unprotected anal sex (RR = 1.35 [95%CI: 1.17 to 1.57]) obtained from local data, and increased risk of suicide (SMR = 6.26 [95%CI: 2.84 to 13.80]) and CVD (SMR = 1.83 [95%CI: 0.39 to 8.57]) mortality associated with cocaine use based on a global systematic review. We estimated the proportion of health harms occurring among MSM/TW who use stimulants in the next year (01-2020/01-2021). We also investigated the 10-year impact (01-2020/01-2030) of: (1) PrEP prioritization for stimulant-using MSM/TW compared to random allocation, and (2) integrating PrEP with a theoretical intervention halving stimulant-associated risk. RESULTS: MSM/TW in Lima will experience high HIV incidence, suicide mortality and CVD mortality (1.6/100 py, and 0.018/100 py, 0.13/100 py respectively) in 2020. Despite stimulant using MSM/TW comprising an estimated 9.5% (95%CI: 7.8 to 11.5) of all MSM/TW, in the next year, 11% 95%CI (i.e. 2.5% to 97.5% percentile) 10% to 13%) of new HIV infections, 39% (95%CI: 18% to 60%) of suicides and 15% (95%CI: 3% to 44%) of CVD deaths could occur among this group. Scaling up PrEP among all stimulant using MSM/TW could prevent 19% (95%CI: 11% to 31%) more HIV infections over 10 years compared to random allocation. Integrating PrEP and an intervention to halve stimulant-associated risks could reduce new HIV infections by 20% (95%CI: 10% to 37%), suicide deaths by 14% (95%CI: 5% to 27%) and CVD deaths by 3% (95%CI: 0% to 16%) over a decade. CONCLUSIONS: MSM/TW who use stimulants experience a disproportionate burden of health harms. Prioritizing PrEP based on stimulant use, in addition to sexual behaviour/gender identity criteria, could increase its impact. Integrated substance use, harm reduction, mental health and HIV care among MSM/TW is needed.

RESUMEN

BACKGROUND: HIV incidence remains high among transgender women in Lima, Peru, most of whom report sex work. On the basis of a stakeholder analysis and health system capacity assessment, we designed a mathematical model to guide HIV programmatic planning among transgender women sex workers (TWSW) in Lima. METHODS: Using a deterministic compartmental model, we modelled HIV transmission among TWSW, their stable partners, and their clients to estimate the impact and cost-effectiveness of combinations of interventions compared with the standard of care on reducing HIV incidence over a 10-year period. We simulated HIV transmission accounting for differences in sexual positioning in anal intercourse and condom use by partner type and fitted the model to HIV surveillance data using Latin hypercube sampling. The interventions we considered were 15% relative increase in condom use with clients and 10% relative increase with stable partners; increase in antiretroviral treatment (ART) coverage at CD4 count lower than 500 cells per mm3 and greater than or equal to 500 cells per mm3; and 15% pre-exposure prophylaxis (PrEP) coverage using generic and branded formulations. We considered a basic scenario accounting for current limitations in the Peruvian HIV services and an enhanced scenario assuming achievement of the UNAIDS 90-90-90 targets and general improvements in HIV services. The 50 best fits according to log-likelihood were used to give the minimum and maximum values of intervention effect for each combination. We used disability-adjusted life-years (DALYs) to measure the negative health outcomes associated with HIV infection that could be averted through the interventions investigated and calculated incremental cost-effectiveness ratios to compare their cost-effectiveness. FINDINGS: Under the basic scenario, combining the four interventions of increasing condom use with clients and stable partners, extending ART to people with CD4 count greater than or equal to 500 cells per mm3, and 15% PrEP coverage with generic drugs would avert 47% (range 27-51) of new infections in TWSW, their clients, and their stable partners over 10 years, with an incremental cost-effectiveness ratio of US$509 per DALY averted. Under the enhanced scenario, this strategy would avert 61% (44-64) of new infections among this population with an incremental cost-effectiveness ratio of $1003 per DALY averted. Under both scenarios, implementation of this strategy approaches or surpasses the 50% incidence reduction goal and would represent a cost-effective use of country resources if generic PrEP drugs are used. The total cost of implementing this strategy under the enhanced scenario would be approximately $1·2 million per year over 10 years, corresponding to 10% of the current Global Fund's yearly contribution in Peru. INTERPRETATION: Investments in HIV services among TWSW in Lima would be cost-effective, even under stringent cost-effectiveness criteria when accounting for setting-specific resource constraints. Notable improvements in HIV testing rates, innovative interventions to increase condom use, and reduced PrEP costs will be key to achieving the 50% incidence reduction goal. Modelling studies incorporating stakeholders' perspectives and health system assessments can bring added value to HIV policy making. FUNDING: National Institutes of Health.

RESUMEN

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. METHODS: Using qualitative methodology to provide an in-depth portrait, we assessed (1) intersections between social marginalization, social capital and HIV vulnerabilities; and (2) community-level resilience strategies employed by TW to buffer against social marginalization and to link to needed HIV-related services in Peru. Between January and February 2015, 48 TW participated (mean age = 29, range = 18-44) in this study that included focus group discussions and demographic surveys. Analyses were guided by an immersion crystallization approach and all coding was conducted using Dedoose Version 6.1.18. RESULTS: Themes associated with HIV vulnerability included experiences of multilevel stigma and limited occupational opportunities that placed TW at risk for, and limited their engagement with, existing HIV services. Emergent resiliency-based strategies included peer-to-peer and intergenerational knowledge sharing, supportive clinical services (e.g. group-based clinic attendance) and emotional support through social cohesion (i.e. feeling part of a community). CONCLUSION: This study highlights the importance of TW communities as support structures that create and deploy social resiliency-based strategies aimed at deterring and mitigating the impact of social vulnerabilities to discrimination, marginalization and HIV risk for individual TW in Peru. Public health strategies seeking to provide HIV prevention, treatment and care for this population will benefit from recognizing existing social capital within TW communities and incorporating its strengths within HIV prevention interventions. At the intersection of HIV vulnerabilities and collective agency, dimensions of bridging and bonding social capital emerged as resiliency strategies used by TW to access needed healthcare services in Peru. Fostering TW solidarity and peer support are key components to ensure acceptability and sustainability of HIV prevention and promotion efforts.

RESUMEN

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., hormone therapy) in Lima, Peru. Perceived acceptability of the integrated care model was high among TW and healthcare professionals alike. Barriers included stigma, lack of provider training or Peruvian guidelines regarding optimal TW care, and service delivery obstacles (e.g., legal documents, spatial placement of clinics, hours of operation). The hiring of TW staff was identified as a key facilitator for engagement in health care. Working in partnership with local TW and healthcare provider organizations is critical to overcoming existing barriers to successful implementation of an integrated HIV services and gender-affirmative medical care model for this key population in Peru.

RESUMEN

Condomless anal intercourse among transgender women (TW) in Peru has been shown to vary by the type of partner involved (e.g. primary vs. casual vs. transactional sex partner), but no previous studies have explored variations in partner-level patterns of condom use according to type of anal intercourse. We evaluated the relationship between partnership characteristics and condom use during insertive (IAI) versus receptive anal intercourse (RAI) among TW with recent, non-female partners. Condomless IAI was more common with transactional and casual sex partners and by TW who self-reported HIV-uninfected serostatus (p < 0.05), alcohol use disorders, or substance use before sex. Condomless RAI was more common with primary partners and by TW who described their HIV serostatus as unknown (p < 0.05). Examining partner-level differences between condomless IAI and RAI reveals distinct patterns of HIV/STI risk among TW, suggesting a need for HIV prevention strategies tailored to the specific contexts of partners, practices, and networks.

RESUMEN

Men who have sex with men (MSM) and transgender women (TW) are key populations in the HIV epidemic. HIV status communication between sex partners can inform decisions regarding sexual behavior. MSM and TW were asked about HIV status communication with sex partners at baseline, 9- and 18-months. GEE models assessed associations with HIV status communication at baseline using prevalence ratios (PRs) and longitudinally using odds ratios (ORs). At baseline, those who had previously had an HIV test, disclosed their HIV status to 42 % of their sex partners. HIV status communication was associated with knowing their sex partner's HIV status at baseline (aPR 5.20) and longitudinally (aOR 1.86). HIV positivity at baseline was negatively associated with HIV status communication during follow-up (aOR 0.55). All reported aPRs and aORs have p < 0.05. Interventions promoting HIV status communication and more frequent HIV testing should be explored as current efforts are insufficient.

RESUMEN

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 TLS in Peru, we summarize challenges encountered in the field and potential strategies to address them. In Brazil, study site selection, cash incentives, and seed selection challenged RDS implementation with MSM. In Peru, expansive geography, safety concerns, and time required for study participation complicated TLS implementation with MSM and transgender women. Formative research, meaningful participation of key populations across stages of research, and transparency in study design are needed to link HIV/AIDS research and practice. Addressing implementation challenges can close gaps in accessing services among those most burdened by the epidemic.
