目的：审查实行更严格的火器立法的影响（1992年《武器法》修正案）在新西兰关于涉及枪支的自杀事件的规定。方法：对立法实施前8年和立法实施后10年的全国自杀数据进行了审查。结果：立法后，与枪支有关的自杀率平均每年下降了46%（p < 0.0001），青年（15-24岁; p < 0.0001）为66%，成人（≥ 25岁; p < 0.01）为39%。与枪支有关的自杀占所有自杀事件的比例也在所有三个人群中下降（p < 0.0001）。然而，枪支立法的引入与所有三个population.Conclusions的自杀率的整体下降并不相关：引入立法限制拥有和获得枪支后，与枪支有关的自杀事件显着减少，特别是在年轻人中。在此期间，青少年自杀的总体比率也有所下降，但无法确定这在多大程度上是由于枪支立法的变化或其他原因造成的。
Objective: To examine the impact of introducing more restrictive firearms legislation (Amendment to the Arms Act, 1992) in New Zealand on suicides involving firearms.Method: National suicide data were examined for 8 years before, and 10 years following the introduction of the legislation.Results: After legislation, the mean annual rate of firearm-related suicides decreased by 46% for the total population (p < 0.0001), 66% for youth (15-24 years; p < 0.0001) and 39% for adults (>= 25 years; p < 0.01). The fraction of all suicides accounted for by firearm-related suicides also reduced for all three populations (p < 0.0001). However, the introduction of firearms legislation was not associated with reductions in overall rates of suicide for all three populations.Conclusions: Following the introduction of legislation restricting ownership and access to firearms, firearm-related suicides significantly decreased, particularly among youth. Overall rates of youth suicide also decreased over this time but it is not possible to determine the extent to which this was accounted for by changes in firearms legislation or other causes.
