Prevalence of anxiety symptoms and disorders in the transgender population: A systematic review of the literature

ABSTRACT

Introduction: Anxiety disorders are the most common mental illness in the general population, affecting 18% of the population in the United States (12 months prevalence) and 13.6% in Europe (life time prevalence). Several studies have also described high rates of anxiety disorders and symptoms of anxiety among the transgender population. There is, however, a great variation of results (particularly related to gender prevalence), and few studies have described the type of anxiety disorders specific to the transgender population.

Aim: To collect and critically appraise the information from the available studies describing prevalence rates of anxiety disorders and symptoms.

Results: A total of 25 cross-sectional (n = 17) and longitudinal (n = 8) studies were found. Cross-sectional studies described higher prevalence rates of anxiety symptoms in the transgender group than in the cis population. The prevalence of anxiety disorders range from 17% to 68%. The most common anxiety disorders found were specific phobias, social phobias, panic disorders, and obsessive-compulsive disorders. Most of the large studies suggest higher levels of anxiety symptoms and disorders in transgender men compared with transgender women; however, considerable variation in results was found.

Conclusions: The findings identified that there is considerable variation in anxiety disorders and symptoms among transgender people attending transgender health services. These findings are likely to be the result of the tools used, the lack of matching controls, and the lack of homogeneity of the group studied. Overall this review indicates high levels of anxiety symptoms and disorders among transgender people attending gender services, primarily (but not exclusively) before commencement of cross-sex hormone treatment. Anxiety disorders related to social interaction (such as social anxiety) and panic attack appear to be particularly common, however more rigorous studies to confirm those findings are needed.
