TOPLINE:
Long-term gender-affirming hormone treatment with testosterone increases the risk for metabolic syndromes in transmasculine individuals, whereas transfeminine individuals receiving estradiol have a lower risk.
METHODOLOGY:
Many transgender individuals receive exogenous sex hormone therapy to reduce gender dysphoria and improve quality of life. These treatments, however, may influence the development of metabolic syndrome.This retrospective, longitudinal cohort study investigated the association between gender-affirming hormone treatment and metabolic syndrome scores in transfeminine and transmasculine individuals compared with cisgender men and women not receiving the treatment.Overall, 645 transgender participants (mean age at index date, 41.3 years; 494 transfeminine and 151 transmasculine) were matched with 645 cisgender participants (280 women and 365 men) from the Veterans Health Administration.Metabolic syndrome scores were calculated based on blood pressure, body mass index (BMI), and levels of high-density lipoprotein (HDL) cholesterol, triglycerides, and blood glucose.Changes in metabolic syndrome scores before and after hormonal transition were compared among transgender and cisgender individuals for the corresponding dates.
TAKEAWAY:
After hormonal transition, all measured metabolic syndrome components significantly worsened in the transmasculine group (P <.05 for all contrast the systolic blood pressure and triglyceride levels decreased hdl cholesterol increased bmi showed no significant change in transfeminine group after hormonal transition.the increase metabolic syndrome scores vs before date of transition was highest transmasculine individuals p followed by cisgender women men>IN PRACTICE:
“This is relevant for the management of metabolic syndrome risk factors in cisgender and transgender individuals and to potentially predict the risk of atherosclerotic cardiovascular disease, type 2 diabetes, systolic hypertension, insulin resistance, and nonalcoholic fatty liver disease,” the authors wrote.

LIMITATIONS:
Causal inferences could not be drawn due to the study’s observational nature. The transmasculine and cisgender female groups were limited in size, and military veterans have special circumstances not representative of the general population. Minority stress among the transgender veterans was also not considered, which may have affected the health and well-being outcomes.
DISCLOSURES:
This study was supported by the National Institutes of Health and Office of Research on Women’s Health grants. One author received grants from the National Institutes of Health.
