Suicide is a significant public health burden in the United States. There is little understanding how policies regarding gun purchasing affects suicide rates. Wisconsin state legislature rescinded a 48-hour waiting period for handgun purchases, which took effect in June 2015.
To determine whether firearm-related suicide increased with the repeal of the 48-hour waiting period for handgun purchases in 2015.
We obtained data through the Wisconsin Department of Health Services via the Wisconsin Interactive Statistics on Health Query System. Suicide rates were compared by Comparative Mortality Figures (CMF).
We reviewed all suicides in Wisconsin between 2012-2014 and 2016-2018. The rate ratios () and second generation P values (p) comparing deaths between 2012-2014 and 2016-2018 indicate significant increases in firearm-related suicide among people of color ( = 1.927; p = 0.0) and among Wisconsinites residing in urban counties ( = 1.379, p = 0.0). There was no significant increase in non-firearm-related suicide ( = 1.117, p = 0.092), nor in firearm-related suicide among White non-Hispanics ( = 1.107, p = 0.164) or Wisconsinites residing in rural counties ( = 1.085, p = 0.500).
Our findings suggest that the repeal of the 48-hour waiting period on handgun purchases in 2015 is correlated with the increase of firearm-related suicides among Wisconsin residents of color and Wisconsinites residing in urban counties.Key Messages:Firearm policies are associated with changes in suicide rates.
自杀在美国是一个严重的公共卫生负担。对于枪支购买政策如何影响自杀率，人们知之甚少。威斯康星州立法机关废除了购买手枪的 48 小时等待期，该等待期于 2015 年 6 月生效。
确定 2015 年废除购买手枪的 48 小时等待期后，与枪支相关的自杀是否增加。
我们通过威斯康星州卫生服务部通过威斯康星州互动健康查询系统获得数据。通过比较死亡率图（CMF）比较自杀率。
我们回顾了 2012-2014 年和 2016-2018 年期间威斯康星州的所有自杀事件。2012-2014 年和 2016-2018 年之间的死亡率比值（ ）和第二代 P 值（ p ）表明，有色人种（ = 1.927； p = 0.0 ）和居住在城市县的威斯康星州居民（ = 1.379，p = 0.0 ）中与枪支相关的自杀率显著增加。非枪支相关自杀（ = 1.117，p = 0.092）或白人非西班牙裔（ = 1.107，p = 0.164）或居住在农村县的威斯康星州居民（ = 1.085，p = 0.500）中与枪支相关的自杀率没有显著增加。
我们的研究结果表明，2015 年取消购买手枪的 48 小时等待期与威斯康星州有色人种居民和居住在城市县的威斯康星州居民中与枪支相关的自杀率增加有关。关键信息：枪支政策与自杀率的变化有关。
