Prospettiva coorte svizzera di individui TRAnsgender e di genere diversi: lo studio SPECTRA
L’obiettivo di questo studio osservazionale è comprendere i fattori che influenzano il benessere e la salute delle persone transgender e di genere diverso (TGD) sottoposte a terapie di affermazione di genere in Svizzera. La popolazione in studio comprende individui TGD di età pari o superiore a 16 anni, in varie fasi della loro transizione medica, compresi coloro che hanno interrotto o effettuato la detransizione.
La domanda principale è:
Quali sono i fattori chiave che influenzano il benessere e i risultati sulla salute degli individui transgender e di genere diverso sottoposti a terapie di affermazione di genere?
I ricercatori confronteranno i risultati sanitari tra diversi sottogruppi, come quelli nelle diverse fasi di transizione o detransizione, per esaminare gli effetti delle terapie di affermazione di genere.
I partecipanti:
Completare questionari elettronici che valutano la congruenza di genere, la qualità della vita, la salute mentale e altri risultati.
Fornire campioni biologici (ad esempio sangue, urina, feci e tamponi cutanei) per le analisi di laboratorio.
Sottoporsi a valutazioni cliniche relative a endocrinologia, fertilità, dermatologia e urologia come parte del loro follow-up di routine.

Popolazione di studio
La popolazione in studio per lo studio SPECTRA sarà composta da individui transgender e di genere diverso (TGD) di età pari o superiore a 16 anni, con diagnosi di incongruenza di genere e che riceveranno assistenza presso i centri sanitari svizzeri partecipanti.

Coorti e interventi
Gruppo / Coorte |
Intervento / Trattamento |
|---|---|
|
Group A: Cohort of Transgender and Gender Diverse individuals in Switzerland
Individuals who present before they start GAHT are included in group A
|
The study program consists of assessments at baseline (before the start of GAHT) and subsequent follow-up visits scheduled at routine intervals which are typically every three months for the first year, every six months for the second year and every twelve months thereafter.
Participants' data collection includes a mix of digital and in-person methods.
Demographical information, clinical and laboratory parameters such as hormone levels which are part of standard clinical care
|
|
Group B: Cohort of Transgender and Gender Diverse individuals in Switzerland
Individuals who are already on GAHT are included in group B
|
The study program consists of a yearly assessment as part of the long-term routine follow-up.
Participants' data collection includes a mix of digital and in-person methods.
Demographical information, clinical and laboratory parameters such as hormone levels which are part of standard clinical care
|
|
Group C: Cohort of Transgender and Gender Diverse individuals in Switzerland
Individuals who undergo gender affirming surgery are (additionally or exclusively) included in group C
|
If GAS is administered, additional assessments are performed preoperatively, and postoperatively in analogy with routine clinical visits, e.g. one week after surgery and then three, six and twelve months later (then once yearly) (e.g.
type of surgery, outcome, patient' satisfaction).
If participants undergo gender-affirming genital surgery, a genital swab and urine analysis (from the urine sample taken for routine testing) will additionally be performed for microbiome analyses as part of the study assessment.

Sexual Desire Inventory (SDI).
The scores for the two dimensions of sexual desire are summed up separately.
Dyadic sexual desire: Scores will range from 0 to 62; while there is no universally established cutoff score that applies across all populations, higher scores at around 50 and upward indicate hypersexuality in the dyadic dimension.
Solitary sexual desire: Scores will range from 0 to 39; while there is no universally established cutoff score that applies across all populations, higher scores at around 31 and upward indicate hypersexuality in the solitary dimension.

Dermatology life quality index (DLQI) is calculated by adding the score of each question, resulting in a maximum of 30 and a minimum of 0. The higher the score, the more quality of life is impaired.
A score higher than 10 indicates that the patient's life is being severely affected by their skin disease.
