OBJECTIVES
We examined the impact of 3 state laws (permit to purchase a handgun, registration of handguns, license to own a handgun) on suicide rates.
METHODS
We used 2010 data from publicly available databases and state legislatures to assess the relationships between our predictors and outcomes.
RESULTS
Results largely indicated that states with any of these laws in place exhibited lower overall suicide rates and suicide by firearms rates and that a smaller proportion of suicides in such states resulted from firearms. Furthermore, results indicated that laws requiring registration and license had significant indirect effects through the proportion of suicides resulting from firearms. The latter results imply that such laws are associated with fewer suicide attempts overall, a tendency for those who attempt to use less-lethal means, or both. Exploratory longitudinal analyses indicated a decrease in overall suicide rates immediately following implementation of laws requiring a license to own a handgun.
CONCLUSIONS
The results are thus supportive of the potential of handgun legislation to have an impact on suicide rates.
目的
我们研究了三项州法律（购买手枪许可证、手枪登记、拥有手枪许可证）对自杀率的影响。
方法
我们使用了2010年来自公开数据库和州立法机构的数据，以评估预测因素与结果之间的关系。
结果
结果大体表明，实施了这些法律中任何一项的州，总体自杀率和枪支自杀率较低，且此类州中较小比例的自杀事件是由枪支导致的。此外，结果表明，要求登记和许可的法律通过枪支导致的自杀比例产生显著的间接影响。后一个结果意味着，此类法律总体上与更少的自杀未遂事件相关，或与试图自杀者倾向于使用致死性较低手段相关，或两者兼而有之。探索性纵向分析表明，在实施要求拥有手枪许可证的法律后，总体自杀率立即下降。
结论
因此，这些结果支持手枪立法可能对自杀率产生影响的观点。
