perjantai 26. kesäkuuta 2026 päivittänyt: Bettina Winzeler, University Hospital, Basel, Switzerland
Sveitsin potentiaalisten transsukupuolisten ja sukupuolten välisten erilaisten yksilöiden kohortti – SPECTRA-tutkimus
Tämän havainnointitutkimuksen tavoitteena on ymmärtää tekijöitä, jotka vaikuttavat Sveitsissä sukupuolta vahvistavia hoitoja saavien transsukupuolisten ja sukupuolidiversiteettien (TGD) hyvinvointiin ja terveyteen. Tutkimuspopulaatio sisältää 16-vuotiaita ja sitä vanhempia TGD-henkilöitä, jotka ovat lääketieteellisen siirtymävaiheen eri vaiheissa, mukaan lukien ne, jotka ovat lopettaneet tai lopettaneet siirtymisen.
Pääkysymys on:
Mitkä ovat tärkeimmät tekijät, jotka vaikuttavat sukupuolta vahvistavia hoitoja saavien transsukupuolisten ja sukupuoliltaan erilaisten yksilöiden hyvinvointiin ja terveyteen?
Tutkijat vertailevat terveystuloksia eri alaryhmissä, kuten siirtymä- tai siirtymävaiheen eri vaiheissa, tutkiakseen sukupuolta vahvistavien hoitojen vaikutuksia.
Osallistujat:
Täytä sähköiset kyselylomakkeet, joissa arvioidaan sukupuolten yhteensopivuutta, elämänlaatua, mielenterveyttä ja muita tuloksia.
Anna biologisia näytteitä (esim. veri-, virtsa-, uloste- ja ihonäytteitä) laboratorioanalyysiä varten.
Käy läpi endokrinologiaan, hedelmällisyyteen, ihotautiin ja urologiaan liittyviä kliinisiä arviointeja osana rutiiniseurantaansa.

Ryhmä/Kohortti |
Interventio / Hoito |
|---|---|
|
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.
