Trans20

Trans20 is a longitudinal cohort study comprising 620 children and adolescents. The study, which commenced in 2017, is embedded in standard clinical care at the Royal Children’s Hospital Gender Service (RCHGS). Trans20 aims to evaluate clinical outcomes of trans and gender diverse children and adolescents. Data is collected from patient during their episode of care with the service (~ yearly) and also once discharged (~every 24 months). Data is collected across multiple domains, including gender identity, mental health, physical health, quality of life and family functioning. This rich dataset offers tremendous opportunities to address important questions in the field of transgender health.
