Optimizing individual health care for children and adolescents with gender dysphoria (GENDA)
2022-2026
Background
This project focuses on evaluating the current health care program for Danish children and adolescents with gender incongruence, which was established in January 2016. There is considerable public and political debate regarding the safety of offering hormonal treatment to young transgender individuals, as this is associated with irreversible changes. Long-term data on physical and psychosocial outcomes are to date sparse. Therefore, systemic unbiased research is much needed. In this project both retrospective and prospective follow-up studies focus on aspects regarding mental health, quality of life, physiological changes, fertility and sexuality.
Aims and Study Design
In this study, we aim to:
- Characterize the psychosocial profile of all children and young people referred for treatment, as well as the natural history of gender identity development and treatment wishes;
- Systematically evaluate biological parameters before, during and under hormonal treatment with GnRH analogues and cross-sex hormones, and to establish a biobank;
- Establish a bio-psycho-social follow-up into adulthood to evaluate treatment satisfaction, quality of life, mental health, somatic health, treatment trajectories in adulthood, possible regrets, fertility and sexuality.
The overall aim is to improve family counseling, clinical care, patient satisfaction, patient safety and ultimately quality-of-life.
The project is registered at clinicaltrials.gov, NCT06573177
