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.

发生铁路自杀的火车站的特点以及火车站内的位置。

背景：为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：我们探讨了发生铁路自杀的车站的特点以及车站内的位置。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月之间的自杀数据，在多元Poisson回归模型中将特定于站的自杀建模为结果变量。（研究2）我们与铁路公司的工作人员一起，参观了自杀频繁发生的车站并进行了实地调查。结果：（研究1）我们使用Poisson回归模型进行的估算显示，当火车站通过火车服务，有大量乘客并位于精神病医院附近时，铁路自杀的发生率更高。（研究2）在50处自杀中，48.0％发生在长凳或候诊室前，26.0％发生在平台的前端，24.0％发生在平台的入口，22.0％发生在自杀的盲点火车司机。局限性：所有数据均由日本的一家铁路公司提供，这限制了结果的推广性。结论：自杀事件频繁发生的站点具有鲜明的特点。关注自杀热点可能有助于预防自杀。经常发生自杀的站点具有鲜明的特征。关注自杀热点可能有助于预防自杀。经常发生自杀的站点具有鲜明的特征。关注自杀热点可能有助于预防自杀。
