Suicide on subway systems is a public health challenge that has been reported in urban centers worldwide. Our objective was to analyze studies of suicide on subway systems, develop a profile of characteristics that are suggestive of association with suicides or attempts, and show how this profile can inform prevention. A literature review involving epidemiology studies and studies relating to subway suicide was conducted. Twenty-eight studies were included in this review. Across studies, characteristics were not often assessed for risk factor status, although several characteristics were remarkably similar. Those attempting suicide on the subway appear to be affected by serious mental illness and have contact with mental health services before the suicidal behavior. Several characteristics may be shared among this population, emphasizing the potential for prevention in clinical and public health domains. Well-designed studies that utilize robust data collection and statistical methods are needed to establish the risk status associated with these characteristics.
地铁系统中的自杀行为是一个已在全球各城市中心被报道的公共卫生挑战。我们的目标是分析有关地铁系统自杀行为的研究，梳理出与自杀或自杀未遂存在关联迹象的特征概况，并展示该概况如何为预防工作提供参考。我们开展了一项文献综述，涵盖流行病学研究以及与地铁自杀相关的研究。本综述纳入了28项研究。在各项研究中，尽管有几个特征显著相似，但通常并未对特征进行危险因素状态评估。那些在地铁上企图自杀的人似乎受到严重精神疾病的影响，并且在自杀行为发生前曾与心理健康服务机构有过接触。这一人群可能具有若干共同特征，凸显了在临床和公共卫生领域开展预防工作的潜力。需要精心设计的研究，运用可靠的数据收集和统计方法来确定与这些特征相关的风险状况。
