A scoping review examining measurement of anti-transgender stigma in low- and middle-income countries.

Globally, transgender and other gender diverse (trans) people experience widespread prejudice, discrimination, violence, and other forms of stigma, which contribute to negative health outcomes. Most anti-trans stigma research has been conducted in high-income countries. Measurement of anti-trans stigma in low- and middle-income countries (LMICs) is important for understanding and improving the health of trans populations globally. Accordingly, this scoping review explores the use of quantitative anti-trans stigma measures in LMICs. This scoping review follows the guidance of the PRISMA extension for Scoping Reviews (PRISMA-ScR) Checklist and examines empirical research with trans populations in LMICs published in English, Spanish, Arabic, and Russian between 2001-2024. Study eligibility criteria included: 1) trans study population, 2) LMIC study location, 3) quantitative or mixed-method study design, and 4) quantitative measurement of anti-trans stigma. The search yielded 82 articles (representing 65 unique studies) from 34 LMICs. Most articles were published since 2018. No articles focused exclusively on trans men. About 62% of articles included a primary focus on stigma; health outcomes primarily examined HIV and mental health. Nearly all articles (95%) measured enacted stigma; other forms of stigma (e.g., internalized and anticipated) were less commonly measured, and structural stigma was only measured in 4 articles. More than half of the articles (55%) measured stigma both broadly and within specific contexts (e.g., from family, in health care). More research exploring anti-trans stigma is needed, especially with trans-masculine and other gender diverse people, measuring outcomes beyond HIV and mental health, and measuring forms of stigma beyond enacted stigma. Expanding and improving measurement of anti-trans stigma in LMICs can improve our understanding of the mechanisms shaping health equity to inform context specific and tailored health interventions to support trans communities worldwide.
