Summary

Researchers at Amsterdam's gender clinic, the largest in the Netherlands, went through the records of everyone referred there over 45 years and checked who had died by suicide. Of 8,263 people, 49 died by suicide, mostly trans women. In recent years the suicide rate was three to four times that of the Dutch population. The rate among trans women fell slightly over the decades, while among trans men it did not change. Suicides happened before, during and after medical transition: 16 were people who had finished genital surgery and only came in for check-ups. The authors conclude that suicide risk stays high at every stage and needs attention throughout care. The study has no matched comparison group and no mental-health data, so it shows the risk but cannot show whether treatment helps or harms.

Key findings

• 1972年から2017年にアムステルダムのクリニックを受診した8,263人（典型的には7.5年追跡）のうち、49人が自殺で亡くなりました（0.6%）。
• 毎年、トランス女性の10万人あたり約64人（41件の死亡、0.8%）とトランス男性の29人（8件の死亡、0.3%）が自殺で亡くなり、トランス女性のリスクは約2倍でした。
• 2013年から2017年の、クリニックの患者の年間の自殺率は10万人あたり40人で、オランダの一般人口では11人でした。
• 自殺のリスクは、トランス女性では年々わずかに下がり、トランス男性では明確な変化は見られませんでした。
• 亡くなった49人のうち、17人は評価中またはホルモンを使用中、2人は手術中、16人は手術を終えて検診のためだけに通っており、14人はもうクリニックと連絡がありませんでした。
• 18歳より前に最初に紹介された人は、自殺の割合（0.2%、4件の死亡）が、成人として紹介された人（0.7%）より低くなっていました。
• 著者らは、自殺のリスクはトランジションのあらゆる段階で続くと結論づけ、ケアの全過程でそれに注意を払うことを勧めています。

Abstract

OBJECTIVE: This study explored the overall suicide death rate, the incidence over time, and the stage in transition where suicide deaths were observed in transgender people. METHODS: A chart study, including all 8263 referrals to our clinic since 1972. Information on death occurrence, time, and cause of death was obtained from multiple sources. RESULTS: Out of 5107 trans women (median age at first visit 28 years, median follow-up time 10 years) and 3156 trans men (median age at first visit 20 years, median follow-up time 5 years), 41 trans women and 8 trans men died by suicide. In trans women, suicide deaths decreased over time, while it did not change in trans men. Of all suicide deaths, 14 people were no longer in treatment, 35 were in treatment in the previous two years. The mean number of suicides in the years 2013-2017 was higher in the trans population compared with the Dutch population. CONCLUSIONS: We observed no increase in suicide death risk over time and even a decrease in suicide death risk in trans women. However, the suicide risk in transgender people is higher than in the general population and seems to occur during every stage of transitioning. It is important to have specific attention for suicide risk in the counseling of this population and in providing suicide prevention programs.

Conclusion

We observed no increase in suicide death risk over time and even a decrease in suicide death risk in trans women. However, the suicide risk in transgender people is higher than in the general population and seems to occur during every stage of transitioning. It is important to have specific attention for suicide risk in the counseling of this population and in providing suicide prevention programs, and to create a safe environment in which these feelings can be discussed at all stages of treatment. Further research is needed into the motives behind suicides to develop adequate prevention programmes.
