To estimate the protective effect of storing firearms locked or unloaded, or both, on the risk of suicide by firearms among people with relatively low intention to die.
Cross sectional survey. The 1993 National Mortality Followback Survey of 22 957 deaths in the United States, representing 2.2 million people, conducted by the National Center for Health Statistics.
Decedent's next of kin answered questions regarding various aspects of decedent's life to supplement information from death certificates.
Compared with decedents who stored their firearm unlocked or loaded, those who stored their firearms locked or unloaded, or both, were less likely to commit suicide by firearms (locked: OR = 0.39, 95% CI = 0.24 to 0.66; unloaded OR = 0.30, 95% CI = 0.18 to 0.49).
This study further supports the utility of devices and practices intended to reduce the likelihood of unauthorised or impulsive use of firearms.
评估将枪支上锁、不上膛或两者兼用对死亡意愿相对较低人群中枪支自杀风险的保护作用。
横断面调查。由国家卫生统计中心开展的1993年美国全国死亡率追踪调查,涉及22957例死亡病例,代表220万人。
死者的近亲回答有关死者生活各方面的问题,以补充死亡证明中的信息。
与枪支未上锁或上膛存放的死者相比,枪支上锁、不上膛或两者兼用的死者通过枪支自杀的可能性较小(上锁:比值比=0.39,95%置信区间=0.24至0.66;不上膛:比值比=0.30,95%置信区间=0.18至0.49)。
本研究进一步支持旨在降低枪支未经授权或冲动使用可能性的装置和做法的效用。
