スイスのTRAnsgenderおよびジェンダー多様な個人の将来コホート - SPECTRA研究
この観察研究の目的は、スイスでジェンダー肯定療法を受けているトランスジェンダーおよびジェンダーダイバーシティ（TGD）の人々の幸福と健康に影響を与える要因を理解することです。 研究対象集団には、医学的移行のさまざまな段階にある16歳以上のTGD患者が含まれており、これには中断または移行解除した人も含まれます。
主な質問は次のとおりです。
ジェンダー肯定療法を受けているトランスジェンダーや性別の多様な人々の幸福と健康結果に影響を与える主な要因は何ですか?
研究者らは、性別肯定療法の効果を調べるために、移行または脱移行のさまざまな段階にあるグループなど、さまざまなサブグループ間の健康結果を比較する予定です。
参加者は次のことを行います:
性別の適合性、生活の質、精神的健康、その他の結果を評価する電子アンケートに回答します。
臨床検査用に生物学的サンプル（血液、尿、便、皮膚綿棒など）を提供します。
定期的なフォローアップの一環として、内分泌学、生殖能力、皮膚科、泌尿器科に関連する臨床評価を受けます。

グループ/コホート |
介入・治療 |
|---|---|
|
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.
