The prevalence and characteristics of handgun purchasers' criminal charge histories have never been described for a large population of firearm owners, but such information is critical to understanding risk factors for subsequent violence in this population. We sought to characterize legal handgun purchasers in California and compare this group to the state population, to quantify the proportion with a criminal charge history at purchase, and to identify modifiable factors associated with of having such a history.
This cross-sectional study of all 79,927 legal handgun purchasers aged 21-49 years in California in 2001 used log-linear generalized additive models to identify factors associated with having a criminal charge history at purchase. Subjects are from a longitudinal study of incident criminal activity among handgun purchasers.
The majority (91.03%) of purchasers were male; whites were overrepresented and Hispanics were underrepresented relative to their population size. At the time of purchase, 16.68% had a criminal charge history and 10.71% had a criminal conviction. Among men with such a history, 31.28% had been charged with a violent crime and 16.54% had been charged with a firearm-related crime. The strongest factor associated with having a criminal charge history was redeeming a pawned handgun (prevalence ratio: 1.82; 95% confidence interval: 1.71, 1.93).
Despite California's stringent firearm purchase laws, more than 1-in-6 handgun purchasers had a criminal charge history at purchase. This proportion may be higher in states with less restrictive firearm purchasing eligibility criteria.
从未有过针对大量枪支拥有者群体描述手枪购买者犯罪指控历史的患病率及特征，但此类信息对于理解该群体后续暴力行为的风险因素至关重要。我们试图描述加利福尼亚州合法手枪购买者的特征，并将该群体与该州人口进行比较，以量化购买时具有犯罪指控历史的比例，并确定与有此类历史相关的可改变因素。
这项对2001年加利福尼亚州所有79927名年龄在21至49岁的合法手枪购买者的横断面研究，使用对数线性广义相加模型来确定与购买时具有犯罪指控历史相关的因素。研究对象来自一项关于手枪购买者犯罪活动事件的纵向研究。
大多数（91.03%）购买者为男性；相对于其人口规模，白人占比过高，西班牙裔占比过低。购买时，16.68%的人有犯罪指控历史，10.71%的人有犯罪定罪记录。在有此类历史的男性中，31.28%曾被指控犯有暴力犯罪，16.54%曾被指控犯有与枪支相关的犯罪。与有犯罪指控历史相关的最强因素是赎回典当的手枪（患病率比：[1.82]；95%置信区间：[1.71, 1.93]）。
尽管加利福尼亚州有严格的枪支购买法律，但超过六分之一的手枪购买者在购买时有犯罪指控历史。在枪支购买资格标准限制较少的州，这一比例可能更高。
