Summary
WPATH, the main international trans health body, part-funded Johns Hopkins to review the evidence for its 2022 treatment guidelines. The reviewers found 20 studies, mostly small European clinic studies. These reported better quality of life and less depression and anxiety after starting hormones, and none reported harm to mental health. But the reviewers rated every conclusion as low-quality evidence, because of biased study designs, small numbers and the effects of surgery being mixed in. Only one study looked at suicide, so no conclusion was possible. The authors still called hormones 'essential' care, a stronger claim than their own ratings support. Court documents released in 2024 showed WPATH tried to control what the Hopkins team could publish. This was the only review published after WPATH brought in an approval rule. It shows weak evidence, not proven benefits.
Key findings
- Derleme, 22 makalede 20 çalışmayı içerdi. Yalnızca biri rastgele kontrollü deneydi; çoğu hasta gruplarını zaman içinde izledi ve dördü tek seferlik fotoğraflardı.
- Çoğu çalışmada 60'tan az kişi vardı ve hepsi uzman cinsiyet kliniklerinden geliyordu. 20 çalışmanın sekizi İtalya'dandı ve yalnızca 3'ü ergenlere baktı.
- Hormonlar daha iyi yaşam kalitesi (7 çalışma), daha az depresyon (12 çalışma) ve daha az anksiyete (8 çalışma) ile ilişkiliydi, ancak birkaç çalışma bir değişiklik bulmadı.
- Derlemeciler kanıtı yaşam kalitesi, depresyon ve anksiyete için düşük kaliteli olarak derecelendirdi ve intihar hakkında hiçbir sonuca varamadı.
- Amsterdam kliniğinden gelen tek intihar çalışması, trans kadınların genel nüfus oranının 5,7 katı oranında intiharla öldüğünü buldu. Derlemeciler bunu ciddi yanlılık riskli olarak değerlendirdi.
- Hollandalı ergen grubunda depresyon, ergenlik engelleyiciler (ergenliği durduran ilaçlar) sırasında düzeldi, ancak daha sonraki karşı cinsiyet hormonlarından sonra başlangıca göre genel iyileşme artık net değildi.
- WPATH, tedavi kılavuzlarını bilgilendirmek için derlemeyi sipariş etti ve kısmen finanse etti.
- 2024'te yayımlanan mahkeme belgeleri, WPATH'ın Hopkins ekibinin makalelerini onaylama hakkı aradığını ve bunun, WPATH bu kuralı getirdikten sonra yayımlanan tek makale olduğunu düşündürüyor.
Abstract
We sought to systematically review the effect of gender-affirming hormone therapy on psychological outcomes among transgender people. We searched PubMed, Embase, and PsycINFO through June 10, 2020 for studies evaluating quality of life (QOL), depression, anxiety, and death by suicide in the context of gender-affirming hormone therapy among transgender people of any age. We excluded case studies and studies reporting on less than 3 months of follow-up. We included 20 studies reported in 22 publications. Fifteen were trials or prospective cohorts, one was a retrospective cohort, and 4 were cross-sectional. Seven assessed QOL, 12 assessed depression, 8 assessed anxiety, and 1 assessed death by suicide. Three studies included trans-feminine people only; 7 included trans-masculine people only, and 10 included both. Three studies focused on adolescents. Hormone therapy was associated with increased QOL, decreased depression, and decreased anxiety. Associations were similar across gender identity and age. Certainty in this conclusion is limited by high risk of bias in study designs, small sample sizes, and confounding with other interventions. We could not draw any conclusions about death by suicide. Future studies should investigate the psychological benefits of hormone therapy among larger and more diverse groups of transgender people using study designs that more effectively isolate the effects of hormone treatment.
Conclusion
Hormone therapy was associated with increased QOL, decreased depression, and decreased anxiety, with similar associations across gender identity and age. Certainty in this conclusion is limited by high risk of bias in study designs, small sample sizes, and confounding with other interventions; the strength of evidence for each outcome was graded low. No conclusions could be drawn about death by suicide. Despite these limitations, the authors stated that hormone therapy is likely associated with improvements in QOL, depression and anxiety, that no study showed harm to mental health, and that these benefits make hormone therapy 'an essential component of care'. They called for larger, more diverse studies using designs that better isolate the effects of hormones.
