Health of transgender men in low-income and middle-income countries: a scoping review

Introduction Despite the rapid growth of research on transgender (trans) health globally, the extent of research on trans men and other transmasculine persons assigned the female sex at birth remains unclear. We, therefore, conducted a scoping review on trans men's health in low-income and middle-income countries (LMICs). Methods The review included peer-reviewed articles and conference abstracts, and grey literature published from 1 January 1999 to 5 July 2019 in English, French, Hindi or Spanish and reporting original quantitative and/or qualitative data on the health of trans men or transmasculine persons living in LMIC. Studies were excluded if they did not disaggregate data for trans men or if they only described surgical techniques or laboratory values. Results We included 53 studies (42 peer-reviewed and 11 grey literature) from 19 LMIC. Most were conducted in higher-middle-income countries (n=12) and in Latin America (n=16, 30.2%), the Middle East (n=14, 26.4%) or Sub-Saharan Africa (n=12, 22.6%) and published in 2014 or later (n=44, 83.0%). Approximately half of studies used quantitative methods (52.8%, n=28), of which 64.3% (n=18) had fewer than 50 participants and 14.2% (n=4) had over 150. Across study designs, social determinants of health and gender-affirming care were the most commonly represented domains (49.1% and 47.1% of studies respectively), with common themes including gender-based violence, coercion and discrimination as well as unprescribed hormone use. Other domains represented included mental health (32.1%), sexual and reproductive health (24.5%), general healthcare access (18.9%), physical health (9.4%) and substance use (9.4%). Conclusion Greater inclusion and disaggregation of trans men and transmasculine persons in global health research is needed to support sex- and gender-based analyses of trans health. Community-based research approaches and theoretically driven research may help to increase the relevance and rigour of such research. Funders should invest in research on trans men's health in LMIC.
