背景 2001 年 9 月 11 日美国发生的恐怖袭击影响了两个欧洲国家的自杀率，而美国总体自杀率保持稳定。然而，尚未研究对袭击地点发生率的影响。目的是检查三个航空公司坠机地点周围地区的袭击后自杀率。方法使用时间序列技术对每日死亡率进行建模。在费率变化显着的情况下，对持续时间和地理范围进行分析。结果在世界贸易中心周围，袭击后 180 天费率显着下降（t=2.4，P=0.0046），而比较条件费率保持稳定。五角大楼或 93 号航班坠机地点没有观察到任何变化。结论 地点的差异效应表明，邻近性可能不如其他事件特征那么重要。哨兵事件后利率波动的时间和地理方面似乎都是可测量的，进一步的分析可能有助于了解社会力量如何影响这些利率。
BackgroundThe terrorist attacks in the USA on 11 September 2001 affected suicide rates in two European countries, whereas overall US rates remained stable. The effect on attack site rates, however, has not been studied.AimsTo examine post-attack suicide rates in areas surrounding the three airline crash sites.MethodDaily mortality rates were modelled using time series techniques. Where rate change was significant, both duration and geographic scope were analysed.ResultsAround the World Trade Center, post-attack 180-day rates dropped significantly (t=2.4, P=0.0046), whereas comparison condition rates remained stable. No change was observed for Pentagon or Flight 93 crash sites.ConclusionsThe differential effect by site suggests that proximity may be less important that other event characteristics. Both temporal and geographic aspects of rate fluctuation after sentinel events appear measurable and further analyses may contribute valuable knowledge about how sociological forces affect these rates.
