To determine whether there is an association between criminal activity and preference for a particular class of handgun among young adults who purchase handguns legally.
Historical cohort study.
Subjects were 5,360 authorized purchasers of handguns in California in 1988 who were 21 to 25 years of age, divided into two groups: all eligible purchasers with a previous criminal history (n = 2,765), and a random sample of purchasers with no such history (n = 2,595). Handguns were classified as small and inexpensive or larger and expensive. Associations were assessed by relative risks adjusted for gender and race or ethnicity.
Handgun purchasers with a previous criminal history were more likely than those without such a history to purchase a small, inexpensive handgun (relative risk (RR) = 1.28; 95% confidence interval (CI), 1.16-1.42). Among handgun purchasers with no previous criminal history, those who purchased a small, inexpensive handgun were more likely than purchasers of other handguns to be charged with new crimes after handgun purchase (RR = 1.73; 95% CI, 1.34-2.24) and were nearly twice as likely to charged with new crimes involving firearms or violence (RR = 1.93; 95% CI, 1.38-2.69).
In this population, criminal activity both before and after handgun purchase was associated with a preference for small, inexpensive handguns.
确定在合法购买手枪的年轻成年人中，犯罪活动与对特定类型手枪的偏好之间是否存在关联。
历史性队列研究。
研究对象为1988年加利福尼亚州5360名年龄在21至25岁之间的授权手枪购买者，分为两组：所有有犯罪前科的合格购买者（n = 2765），以及无此类前科的购买者随机样本（n = 2595）。手枪分为小型廉价手枪或大型昂贵手枪。通过对性别、种族或族裔进行调整后的相对风险评估关联。
有犯罪前科的手枪购买者比无前科的购买者更有可能购买小型廉价手枪（相对风险（RR）= 1.28；95%置信区间（CI），1.16 - 1.4）。在无前科的手枪购买者中，购买小型廉价手枪的人比购买其他手枪的人在购买手枪后更有可能被指控犯新罪（RR = 1.73；95% CI，1.34 - 2.24），并且被指控犯涉及枪支或暴力新罪的可能性几乎是后者的两倍（RR = 1.93；95% CI，1.38 - 2.69）。
在这一人群中，购买手枪前后的犯罪活动均与对小型廉价手枪的偏好有关。
