This study is the first comprehensive analysis to investigate the potential association between stock market fluctuations and attempted suicide events as measured by self-inflicted injuries treated in hospitalization. Using nationwide, 15-year population-based data from 1998 through 2012, we observe that the occurrences for the hospitalizations of attempted suicides are apparently predicted by stock price movements. A low stock price index, a daily fall in the stock index, and consecutive daily falls in the stock index have been shown to be associated with increased risk of hospitalization in patients with attempted suicide. More specifically, stock price index is found to be significant impact on attempted suicide in the 45-54 age groups of both genders, whilst daily change is significant for both genders in the 25-34 and 55-64 age groups and accumulated change is only significant in female aged 25-44 and above 65. On the basis of the results, relevant organizations should consider the suicidal factors that relate prime-working-age and near-retirement-age people to better carry out specific suicide prevention measures, and, meanwhile, encourage those people to pay less attention towards daily stock price movements.
这项研究首次全面分析了股票市场波动与以住院治疗的自我伤害衡量的自杀未遂事件之间的潜在关联。使用 1998 年至 2012 年 15 年的全国人口基础数据，我们观察到住院自杀未遂事件的发生显然可以通过股票价格走势来预测。低股价指数、股价指数的每日下跌以及股价指数的连续每日下跌与自杀未遂患者住院风险增加相关。更具体地说，发现股价指数对两性中 45-54 岁年龄组的自杀未遂有显著影响，而每日变化对两性中 25-34 岁和 55-64 岁年龄组均有显著影响，累积变化仅在 25-44 岁和 65 岁以上的女性中显著。基于这些结果，相关组织应该考虑与主要工作年龄和接近退休年龄的人相关的自杀因素，以便更好地实施特定的自杀预防措施，同时鼓励这些人减少对日常股价波动的关注。
