Substance use patterns among a global sample of transgender and non-binary people during the COVID-19 pandemic

Abstract

Abstract Background Transgender and non-binary (TNB) people are at high risk of substance misuse compared to cisgender individuals. Few studies have described substance use among non-binary people, and many studies have focused solely on samples from Western countries. In this global study of TNB people, we sought to identify intra-group differences, risk factors, and COVID-related changes in the use of tobacco, alcohol, and cannabis. Methods We used cross-sectional data from 926 TNB users of the Hornet app across 76 countries between October and November 2020. Participants self-reported the use of tobacco, alcohol, and cannabis in the past 6 months and any changes in use during the pandemic. We generated descriptive statistics and used logistic regression to assess substance use between TNB subgroups, identify risk factors for each substance by gender identity, and identify changes in substance use before and during the pandemic. Results Most TNB participants used tobacco (53.7%, n = 498) and alcohol (66.3%, n = 614). Non-binary participants had increased odds of using cannabis (adjusted odds ratio: 1.62, 95% CI 1.03, 2.55) compared to transfeminine participants. Participants’ geographic region of residence was most associated with higher substance use, compared to other potential factors. Most participants reported increases in at least one substance during COVID-19 (54.2%, n = 276 of 518 responses). Conclusions In this global TNB sample, we found that substance use varied by gender identity, and changes in substance use during the pandemic varied by TNB sub-groups. We join researchers calling for gender-specific tailoring of substance-related services for TNB clients and urge further studies with greater inclusion and disaggregation of non-binary and transmasculine individuals to support better-informed analysis of transgender health.
