Youth suicide rates in Japan are among the highest globally, highlighting the urgent need for targeted prevention strategies. Within this context, schools can offer significant protective factors by shaping both identity development and mental health outcomes, but such protective effects have not examined in Japanese LGB+ populations. To address this research gap, this examined correlates of suicidal ideation and suicide attempts among LGB+ students in the past 12 months in Japanese educational settings.
Multivariable logistic regression examined associations between recent suicidal ideation and suicide attempt and experiences of sexuality or gender-based harassment, exclusion, and school support structures among 2,095 LGB+ students aged 15-25 years in Japan from an anonymous online survey.
Results revealed high rates of suicidal ideation (32.3 %) and attempts (8.8 %) in the past 12 months. Sexuality and gender identity-based harassment, exclusion and hearing negative remarks about sexuality in educational settings were linked to higher suicidal ideation and suicide attempts. Supportive LGBT clubs and alliances and LGBT-inclusive anti-bullying policies at educational settings were associated with lower rates of suicidal ideation.
The findings highlight the urgent need for school-based interventions to mitigate the elevated risk of suicidality among LGB+ youth in Japan. Establishing safe and supportive educational environments may help reduce the heightened suicide risk faced by this vulnerable population.
日本的青少年自杀率在全球名列前茅，这凸显了制定针对性预防策略的迫切需求。在此背景下，学校可以通过塑造身份认同发展和心理健康结果提供重要的保护因素，但这种保护作用在日本的LGB+人群中尚未得到研究。为了填补这一研究空白，本研究调查了日本教育环境中LGB+学生在过去12个月内自杀意念和自杀未遂的相关因素。
通过多变量逻辑回归分析，对来自一项匿名在线调查的2095名年龄在15至25岁的日本LGB+学生中，近期自杀意念和自杀未遂与性取向或基于性别的骚扰、排斥以及学校支持结构之间的关联进行了研究。
结果显示，在过去12个月内，自杀意念发生率较高（32.3%），自杀未遂发生率为8.8%。在教育环境中，基于性取向和性别认同的骚扰、排斥以及听到有关性取向的负面言论与较高的自杀意念和自杀未遂相关。教育环境中支持性的LGBT俱乐部和联盟以及包含LGBT群体的反欺凌政策与较低的自杀意念发生率相关。
研究结果凸显了在日本开展以学校为基础的干预措施以降低LGB+青少年自杀风险升高的迫切需求。建立安全且支持性的教育环境可能有助于降低这一弱势群体面临的更高自杀风险。
