Background: To devise effective railway suicide countermeasures, it is necessary to identify stations where suicide is likely to occur. Aim: We explored the characteristics of stations where railway suicides have occurred and locations within the stations. Method: (Study 1) Using suicide data from between April 2014 and September 2019 provided by a major railway company in Japan, station-specific suicide was modeled as an outcome variable in a multivariate Poisson regression model. (Study 2) With railway company staff, we visited stations where suicide frequently occurs and conducted fieldwork. Results: (Study 1) Our estimation using a Poisson regression model revealed that railway suicides were more frequent when stations were serviced by passing trains, had a large number of passengers, and were located near psychiatric hospitals. (Study 2) Of 50 suicides, 48.0% occurred in front of benches or waiting rooms, 26.0% occurred at the front end of the platform, 24.0% occurred at the entrance to the platform, and 22.0% occurred at a blind spot for the train driver. Limitations: All data were provided by one railway company in Japan, limiting the generalizability of the results. Conclusion: Stations where suicide occurs frequently have distinct characteristics. Focusing on suicide hotspots may aid suicide prevention.

发生铁路自杀事件的火车站特征和站内位置。

背景：为了制定有效的铁路自杀对策，有必要确定可能发生自杀的车站。目的：我们探索了铁路自杀事件发生的车站的特征和车站内的位置。方法：（研究 1）使用日本一家主要铁路公司提供的 2014 年 4 月至 2019 年 9 月期间的自杀数据，将特定车站自杀建模为多元泊松回归模型中的结果变量。（研究2）我们和铁路公司的工作人员一起走访了自杀多发的车站，并进行了实地考察。结果：（研究 1）我们使用泊松回归模型的估计表明，当车站有过往列车服务、有大量乘客并且位于精神病院附近时，铁路自杀的频率更高。（研究二） 50 起自杀事件中，48.0% 发生在长椅前或候车室前，26.0% 发生在站台前端，24.0% 发生在站台入口处，22.0% 发生在站台盲点。火车司机。局限性：所有数据均由日本的一家铁路公司提供，限制了结果的普遍性。结论：自杀频发的车站具有鲜明的特点。关注自杀热点可能有助于预防自杀。经常发生自杀事件的车站具有鲜明的特点。关注自杀热点可能有助于预防自杀。
