Examining Differences in Substance Use Outcomes and Related Correlates among Transfeminine and Transmasculine Adults...

Background: Transgender persons in the U.S. experience high levels of violence and discrimination which have been linked to adverse substance use outcomes. Despite transgender women's higher exposure to such deleterious events compared to transgender men, studies have often aggregated both transgender women and men, obfuscating potentially unique differences between these groups. The current study, guided by the Minority Stress Model, examines differences in substance use outcomes and related correlates among transfeminine and transmasculine adults. Methods: A secondary data analysis was conducted using the 2017 Patient Characteristics Survey of public mental health facilities in the state of New York (N = 1387). Controlling for theoretically relevant factors, logistic regression models were estimated to examine differences between transfeminine and transmasculine adults in alcohol-related disorder (ARD) and drug use-related disorder (DURD) diagnoses, and tobacco use. Correlates of substance use disparities were also examined within gender identity groups. Results: Overall, 35% of participants were documented as using tobacco products whereas 14 and 19% were diagnosed with ARDs and DURDs, respectively. Transfeminine participants were 1.44-times more likely to be diagnosed with ARDs relative to transmasculine adults. Compared to transmasculine and White participants, transfeminine and Black participants were 1.64- and 1.59-times more likely to be diagnosed with DURDs. Conclusions: Recognizing the observed higher hazardous substance use risk among transfeminine and Black participants, findings indicate the potential role of minority stress in health outcomes of stigmatized communities. Our findings emphasize the need for identifying prevention and treatment strategies aimed at mitigating the implications of minority stress.
