Mental Health of Transmasculine Adults Receiving Gender-Affirming Hormone Therapy in Thailand.

Purpose: Many studies have shown conflicting results regarding mental health among transmasculine adults or transgender men (TM). This study aimed to identify the prevalence of depression among Thai TM receiving gender-affirming hormone therapy (GAHT).

Methods: All TM, over 18 years of age, who received GAHT for at least three consecutive months were invited to complete a self-report questionnaire that covered participants' demographic and clinical data. Mental health, including depression, anxiety, and quality of life (QoL), was assessed. We reported the prevalence of mental illnesses and examined the correlations between mental health scores and other associated data.

Results: A total of 84 TM were included in the analysis. Major depression and generalized anxiety disorder were detected in 14.3% and 3.6%, respectively. Depression severity was negatively associated with age and QoL. Depression and anxiety severity were found to be positively associated.

Conclusions: Compared with the general Thai population, the prevalence of mental health problems among Thai TM receiving GAHT was higher. Age of maturity may be a potential mental health protective factor, and assessment in younger individuals may benefit mental health.
