Adaptation of the U.S.-oriented evidence-based intervention TransAction for transgender women in Vietnam.

Background: Trans women in Vietnam are among the most vulnerable groups with high HIV risk and limited access to care. TransAction is an evidence-based intervention to reduce trans women's HIV risks and increase social support and access to care.Aims: The aim of this study was to adapt TransAction to the specific needs of trans women in Vietnam. Methods: This study was conducted in Ho Chi Minh City from November 2020 through June 2021 Using the ADAPT-ITT framework, interviews, focus groups, and community advisory board meetings were conducted with trans women, service providers, and community members to better understand Vietnamese contexts of gender transition, HIV risks, and service gaps. Feedback was solicited on TransAction content and format adaptation. Results: Trans women in Vietnam faced unique challenges related to family norms, policy and regulatory constraints, and limited transgender-specific or gender-inclusive services. TransAction was modified to accommodate identified challenges and needs, and intervention components to enhance family support were added. Strategies to cope with stigma and seek support and services were adapted to Vietnamese culture and policies. Discussion: Post-adaptation interviews and focus groups demonstrated strong feasibility and acceptability for the adapted intervention, which can potentially be used to reduce Vietnamese trans women's HIV risks and increase their social support.

An adaptive design to screen, treat, and retain people with opioid use disorders who use methamphetamine in methadone clinics (STAR-OM): study protocol of a clinical trial.

BACKGROUND: Methamphetamine use could jeopardize the current efforts to address opioid use disorder and HIV infection. Evidence-based behavioral interventions (EBI) are effective in reducing methamphetamine use. However, evidence on optimal combinations of EBI is limited. This protocol presents a type-1 effectiveness-implementation hybrid design to evaluate the effectiveness, cost-effectiveness of adaptive methamphetamine use interventions, and their implementation barriers in Vietnam. METHOD: Design: Participants will be first randomized into two frontline interventions for 12 weeks. They will then be placed or randomized to three adaptive strategies for another 12 weeks. An economic evaluation and an ethnographic evaluation will be conducted alongside the interventions. PARTICIPANTS: We will recruit 600 participants in 20 methadone clinics. ELIGIBILITY CRITERIA: (1) age 16+; (2) Alcohol, Smoking and Substance Involvement Screening Test (ASSIST) scores ≥ 10 for methamphetamine use or confirmed methamphetamine use with urine drug screening; (3) willing to provide three pieces of contact information; and (4) having a cell phone. OUTCOMES: Outcomes are measured at 13, 26, and 49 weeks and throughout the interventions. Primary outcomes include the (1) increase in HIV viral suppression, (2) reduction in HIV risk behaviors, and (3) reduction in methamphetamine use. COVID-19 response: We developed a response plan for interruptions caused by COVID-19 lockdowns to ensure data quality and intervention fidelity. DISCUSSION: This study will provide important evidence for scale-up of EBIs for methamphetamine use among methadone patients in limited-resource settings. As the EBIs will be delivered by methadone providers, they can be readily implemented if the trial demonstrates effectiveness and cost-effectiveness.

HIV Prevalence and Factors Related to HIV Infection Among Transgender Women in Vietnam: A Respondent Driven Sampling Approach.

Transgender women are at higher risk of HIV infection, however, there is a lack of information about HIV infection and related factors among transgender women in Vietnam. From February 2018 to June 2018, 456 transgender women were recruited in the study using Respondent-Driven Sampling technique. Participants completed the computer-based questionnaire and were tested for HIV serostatus. Multivariable logistic regression was used to identify factors related to HIV infection. The prevalence of HIV infection was 77 (16.5%), of which 19 (24.7%) were not aware of their HIV-positive status prior to the study. Factors associated with HIV infection included popper use (aOR 2.01, p = 0.044) and having regular male partner(s) (aOR 0.42, p = 0.006). More efforts are needed to reduce the high prevalence of HIV infection, such as expanding the reach of HIV screening and prevention programs to the transgender women population, particularly for substance users.
