Background: Transgender and gender diverse (TGD) individuals have elevated mental and physical health disparities and a greater mortality risk compared to their cisgender (non-TGD) counterparts.
Methods: We assessed differences in the association of depression with all-cause and cardiovascular disease (CVD) mortality among TGD and cisgender Veterans Administration patients. A sample of 8981 TGD patients, matched 1:3 with cisgender patients (n = 26,924) patients, was created from administrative and electronic health record data from October 1, 1999 to December 31, 2016. Cox proportional regression models stratified by gender modality (i.e., TGD and cisgender) were used to assess the hazard of all-cause and CVD mortality associated with a history of depression.
Results: Adjusted models demonstrated that depression was significantly associated with a greater hazard of all-cause mortality among both TGD (aHR:1.18, 95 % CI: 1.04-1.34) and cisgender (aHR:1.22, 95 % CI: 1.17-1.28) patients. Similar to all-cause mortality, depression was significantly associated with a greater hazard of CVD mortality among cisgender patients ≥65 years (aHR = 1.23, 95 % CI = 1.13-1.35). Findings for TGD patients showed a similar pattern, though results were not significant.
Limitations: Hazards may be underestimated since depression may be underdiagnosed. Further, we were unable to adjust for other health-related risk factors tied to mortality (e.g., smoking).
Conclusion: Overall, depression was associated with a greater hazard of all-cause mortality among both TGD and cisgender patients. Future work should assess the equity of reach, quality, and outcomes of treatment for depression for TGD populations given the lack of attention to addressing the needs of this important patient demographic.
