Clinical Trial Summary

Data about transgender medical care, especially the gender-affirming hormone therapy (GAHT) is extremely insufficient in China. Few evidence exists in the physical and psychological effects of the hormonal treatment in Chinese transgender population. CGAHT is designed to describe the social and mental condition of transgender people who are seeking for formal GAHT, and to investigate the physical and psychological effects of GAHT on this population in China.

Description:

CGAHT will be conducted in one of the main transgender medical centers in Chinese mainland. Participants who are seeking for the start of GAHT will be enrolled from clinical visitors. Before GAHT, participants will be interviewed with questionaries about their life experience, gender identity and social economic conditions. Evaluations on mental and physical health will be performed at baseline and during the GAHT. Participants will be followed up to 12 months. GAHT will be given to transgender people according to the protocol recommended by the international guideline (doi: 10.1210/jc.2017-01658) .

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change from Baseline Insulin Sensitivity at 12 months	Insulin sensitivity will be assessed with composite insulin sensitivity index (ISI), which is calculated as 10 000/v[(fasting glucose [mg/dL]) ×(fasting insulin [µU/mL]) × (mean glucose [mg/dL]) × (mean insulin [µU/mL])], using 0 min, 60 min, and 120 min values of oral glucose tolerance test (OGTT). Composite ISI will be evaluated at baseline and every 6 months until 12 months of GAHT.	12 months
Primary	Change from Baseline Beta-cell Function at 12 months	Beta-cell function will be assessed with oral glucose tolerance test-derived disposition index (DI). First, 60 min insulinogenic index (IGI60) is calculated as (insulin60 min-insulin0 min[µU/mL])/(glucose60 min-glucose0 min [mmol/L]), using 0 min and 60 min values of OGTT. Then DI is calculated by multiplying IGI60 with composite ISI to reflect beta-cell function adjusting for the insulin sensitivity. DI will be evaluated at baseline and every 6 months until 12 months of GAHT.	12 months
Primary	Change from Baseline Bone Mineral Density at 12 months	Bone mineral densities (g/cm^2) of lumber spine and hip will be evaluated by dual-energy X-ray absorptiometry at baseline and 12 months of GAHT.	12 months
Primary	Depression Changes from Baseline Psychological Questionnaires at 12 months	Patient Health Questionnaire will be tested at baseline and every 3 months until 12 months to understand the effects of GAHT	12 months
Primary	Anxiety Changes from Baseline Psychological Questionnaires at 12 months	Generalized anxiety disorder scale will be tested at baseline and every 3 months until 12 months to understand the effects of GAHT	12 months
Primary	Suicide Ideation Changes from Baseline Psychological Questionnaires at 12 months	Beck scale for suicide ideation will be tested at baseline and every 3 months until 12 months to understand the effects of GAHT	12 months
Primary	Gender Dysphoria Changes from Baseline Psychological Questionnaires at 12 months	Utrecht gender dysphoria scale will be tested at baseline and every 3 months until 12 months to understand the effects of GAHT	12 months
Primary	Social Exclusion Changes from Baseline at 12 months	Cyberball task will be tested at baseline and every 3 months until 12 months to understand the effects of GAHT.	12 months
Primary	Functional brain Change after 6 months of GAHT	Change of functional connectivity will be analyzed to understand at 6 months of GAHT.	6 months
Secondary	Incidence of Treatment-Emergent Adverse Events	The incidence of adverse events during the 12 months of GAHT will be calculated, including thromboembolic events, drug-induced liver injury, hyperkalemia, newly diagnosed cardiovascular disease, erythrocytosis and newly diagnosed tumor.	Up to 12 months
Secondary	Change from Baseline Body Mass Index at 12 months	Body mass index is calculated as [weight (kg) / height (m)^2], which will be evaluated at baseline and every 3 months until 12 months of GAHT.	12 months
Secondary	Change from Baseline Waist-hip Ratio at 12 months	Waist-hip ratio is calculated as [waist (cm)/hip (cm)], which will be evaluated at baseline and every 3 months until 12 months of GAHT.	12 months
Secondary	Change from Baseline Body Composition at 12 months	Fat percentage (%) and lean mass (kg) will be assessed using the InBody S10. The body composition will be evaluated at baseline and 12 months of GAHT.	12 months
Secondary	Change from Baseline Breast Volume of transgender women at 12 months	Breasts of transgender women will be shot in 360° with 3D photography. The volume (ml) of both sides will be measured by the image analysis at baseline and every 6 months until 12 months of GAHT.	12 months
Secondary	Change from Baseline Homeostatic Model Assessment Index (HOMA-IR) at 12 months	HOMA-IR is calculated as [(fasting insulin [µU/mL] × fasting glucose [mmol/L])/22.5]. HOMA-IR will be evaluated at baseline and every 6 months until 12 months of GAHT.	12 months
Secondary	Change from Baseline Homeostatic Model Assessment of Beta-cell function (HOMA-ß) at 12 months	HOMA-ß is calculated as [20 × (fasting insulin [µU/mL]) × (fasting glucose -3·5 [mmol/L])]. HOMA-ß will be evaluated at baseline and every 6 months until 12 months of GAHT.	12 months
