目标.本研究的目的是确定是否购买手枪从持牌经销商与杀人或自杀的风险，以及是否有任何协会变化的时间，因为购买。在一个大型健康维护组织的成员中进行了病例对照研究。研究对象为1980年至1992年的353名自杀者和117名杀人者。五名对照组受试者与每个病例受试者的年龄、性别和居住地的邮政编码相匹配。手枪购买信息是从许可证部获得的。对于有家庭手枪购买史的人，自杀的校正相对风险为1.9（95%置信区间[CI] = 1.4，2.5）。考虑到家庭手枪购买史，调整后的杀人相对风险为2.2（95%CI = 1.3，3.7）。无论是自杀还是他杀，购买后5年以上的相对风险持续升高。法律的购买手枪似乎与暴力死亡风险的长期增加有关。
Objectives. The purpose of this study was to determine whether purchase of a handgun from a licensed dealer is associated with the risk of homicide or suicide and whether any association varies in relation to time since purchase.Methods. A case-control study was done among the members of a large health maintenance organization. Case subjects were the 353 suicide victims and 117 homicide victims among the members from 1980 through 1992. Five control subjects were matched to each case subject on age, sex, and zip code of residence. Handgun purchase information was obtained from the Department of Licensing.Results. The adjusted relative risk for suicide was 1.9 (95% confidence interval [CI] = 1.4, 2.5) for persons with a history of family handgun purchase from a registered dealer. The adjusted relative risk for homicide, given a history of family handgun purchase, was 2.2 (95% CI = 1.3, 3.7). For both suicide and homicide, the elevated relative risks persisted for more than 5 years after the purchase.Conclusions. Legal purchase of a handgun appears to be associated with a long-lasting increased risk of violent death.
