Effects of Gender-Affirming Hormone Therapy on Cardiovascular, Metabolic, and Mental Health Outcomes in Transgender Adults.

The objective of this observational study is to examine the impact of gender-affirming hormone therapy (GAHT) on mood in transgender individuals and to explore its potential association with early atherosclerotic processes. The main questions it aims to answer are: * Whether GAHT in transgender individuals has a psychological and functional impact, assessed through mood, stress, and self-esteem. Additionally, the study will analyze whether morphofunctional changes (including body composition, muscle strength, cardiorespiratory fitness, and metabolic flexibility) are related to inflammatory responses and psychological well-being. * Whether the administration of GAHT poses a cardiovascular risk by influencing biochemical, inflammatory, and oxidative markers, mitochondrial function, and the activation of the NLRP3 inflammasome in leukocytes. Participants will undergo evaluation of early stages of the atherosclerotic process through the analysis of leukocyte-endothelial interactions, adhesion molecule expression, and ankle-brachial index (ABI), as well as periodontal parameters. Overall, this study aims to contribute to improving healthcare delivery and promoting more equitable and gender-affirming medical services tailored to the needs of transgender individuals.

Swiss ProspectivE Cohort of TRAnsgender and Gender Diverse Individuals - the SPECTRA Study

The goal of this observational study is to understand the factors influencing the well-being and health of transgender and gender-diverse (TGD) individuals undergoing gender-affirming therapies in Switzerland. The study population includes TGD individuals aged 16 and older, at various stages of their medical transition, including those who have discontinued or detransitioned. The main question is: What are the key factors influencing the well-being and health outcomes of transgender and gender-diverse individuals undergoing gender-affirming therapies? Researchers will compare health outcomes across different subgroups, such as those at different stages of transition or detransition, to examine the effects of gender-affirming therapies. Participants will: Complete electronic questionnaires assessing gender congruence, quality of life, mental health, and other outcomes. Provide biological samples (e.g., blood, urine, stool, and skin swabs) for laboratory analysis. Undergo clinical evaluations related to endocrinology, fertility, dermatology, and urology as part of their routine follow-up.
