Finnish register: psychiatric needs did not subside after medical gender reassignment

Ruuska, Tuisku, Holttinen, and Kaltiala compared 2,083 under-23s referred to Finnish gender services (1996–2019) with 16,643 matched controls. Specialist psychiatric care was already higher before referral and still higher two or more years later. It rose among those who received medical gender reassignment. The authors: psychiatric needs do not subside after that pathway.

Psychiatric need did not go away after the clinic pathway. That is what this Finnish register shows.

On 4 April 2026, Acta Paediatrica e-published Ruuska, Tuisku, Holttinen, and Kaltiala: Psychiatric Morbidity Among Adolescents and Young Adults Who Contacted Specialised Gender Identity Services in Finland in 1996–2019. Same nationwide cohort as their 2024 suicide-death paper: 2,083 gender-referred people under 23 vs 16,643 matched controls.

The outcome here is specialist-level psychiatric treatment, not suicide deaths. It was already higher before referral (45.7% vs 15.0%) and still higher two or more years after (61.7% vs 14.6%). Among those who received what the authors call medical gender reassignment — sex-rejecting procedures — the share in specialist psychiatric care rose: 9.8% to 60.7% after feminising reassignment, 21.6% to 54.5% after masculinising. The authors: psychiatric needs do not subside after medical gender reassignment.
