This study examines correlates of suicidal ideation and attempts in the past 12 months among lesbian, gay, bisexual, pansexual, queer, asexual and questioning (LGB+) youth in Japan, where youth suicide rates are among the highest globally.
Data were drawn from a 2024 national cross-sectional online survey in Japan, analysing 3380 cisgender LGB+ individuals aged 15-25 years. Multivariable logistic regressions were conducted to identify significant correlates regarding suicidal ideation and suicide attempts in the past 12 months.
In total, 30.6 % of participants reported suicidal ideation, and 8.3 % reported suicide attempts in the past 12 months. In the multivariable regression analyses, bisexual and heterosexual-identifying participants had lower odds of experiencing suicidal ideation compared to their gay-identifying peers. Cisgender women showed higher odds of suicidal ideation than cisgender men. Living in rural or remote areas, experiencing verbal, physical or sexual harassment or being socially excluded based on sexuality or gender identity, and homelessness were all associated with increased odds of suicidal ideation. Cisgender women had higher odds of a suicide attempt compared to cisgender men. Harassment and social exclusion based on sexuality or gender identity, and recent homelessness were strongly associated with higher odds of suicide attempts.
This study underscores the need for targeted suicide prevention policies for LGB+ youth in Japan, focusing on anti-harassment measures, LGB+-affirming rural support services, and homelessness prevention. Moreover, these findings highlight the need for LGB+ youth to be explicitly identified as a priority population for suicide prevention in Japan when youth suicide is at record highs.
本研究调查了日本女同性恋、男同性恋、双性恋、泛性恋、酷儿、无性恋及性取向存疑（LGB+）的青少年在过去12个月内自杀意念和自杀未遂的相关因素，日本的青少年自杀率在全球处于最高水平之列。
数据来自2024年日本全国性横断面在线调查，分析了3380名年龄在15至25岁的顺性别LGB+个体。进行多变量逻辑回归以确定过去12个月内自杀意念和自杀未遂的显著相关因素。
总体而言，30.6%的参与者报告有自杀意念，8.3%的参与者报告在过去12个月内有自杀未遂行为。在多变量回归分析中，与自我认同为同性恋的同龄人相比，自我认同为双性恋和异性恋的参与者出现自杀意念的几率较低。顺性别女性出现自杀意念的几率高于顺性别男性。生活在农村或偏远地区、遭受言语、身体或性方面的骚扰或因性取向或性别认同而被社会排斥以及无家可归都与自杀意念几率增加有关。与顺性别男性相比，顺性别女性自杀未遂的几率更高。基于性取向或性别认同的骚扰和社会排斥以及近期无家可归与自杀未遂几率大幅增加密切相关。
本研究强调日本需要针对LGB+青少年制定有针对性的自杀预防政策，重点是反骚扰措施、支持LGB+群体的农村服务以及预防无家可归。此外，这些研究结果凸显，在日本青少年自杀率创历史新高之际，需要明确将LGB+青少年确定为自杀预防的优先人群。
