The U.S. suicide rate has increased 35% since 1999. The role of the Internet has not been thoroughly investigated despite Internet use more than doubling from 1999 to present. The majority of U.S. suicide deaths are by firearm; however, there is no examination of the association between trends in firearm Internet searches and overall and firearm monthly suicide rates. We hypothesized that search strings related to firearm suicide would be significantly associated with monthly suicide rates (both all methods and firearm).

2004-2016 年与枪支相关的 Google 搜索和美国自杀率的时间序列分析

自 1999 年以来，美国的自杀率增加了 35%。尽管互联网使用量从 1999 年到现在增加了一倍多，但互联网的作用尚未得到彻底调查。大多数美国自杀死亡是由枪支造成的。然而，没有研究枪支互联网搜索趋势与总体和每月枪支自杀率之间的关联。我们假设与枪支自杀相关的搜索字符串与月自杀率（所有方法和枪支）显着相关。
