目的：枪支死亡率在美国是一个严重的问题。以前的研究主要集中在国家或州一级的枪支死亡率，留下了州内差异的问题。这项研究调查了加利福尼亚州的枪支死亡率。方法：我们使用多个死因数据文件来确定2000年至2015年加州所有的枪支死亡人数。我们描述了枪支死亡率和随时间推移的计数，按年龄和县，按意图、性别和种族/族裔分层。结果：从2000年到2015年，加州发生了24,922起枪杀案和23,682起枪杀案。自2000年代中期以来，枪杀率下降了30%，自杀率上升了1%，但这些趋势因县而异。由于大都市地区的枪杀率下降，到2015年，城市和农村县之间的枪杀率没有显著差异。非西班牙裔黑人男性的枪杀率最高，但西班牙裔男性的死亡人数最多。结论：我们发现加州的枪支死亡率在州内存在相当大的差异。我们的研究结果将引起研究人员、政策制定者和公共卫生从业者的兴趣。其他州的枪支死亡率也有类似的流行病学特征。(C)2018 Elsevier Inc.保留所有权利。
Purpose: Firearm mortality is a significant problem in the United States. Previous studies have largely focused on firearm mortality at the national or state level, leaving open the question of within-state variation. This study examined firearm mortality within California.Methods: We used Multiple Cause of Death data files to identify all firearm fatalities in California from 2000 to 2015. We described firearm mortality rates and counts over time, by age and county, stratifying by intent, gender, and race/ethnicity. County-level rates were smoothed with empirical Bayes estimates from random-effect Poisson models.Results: From 2000 to 2015, there were 24,922 firearm homicides and 23,682 firearm suicides in California. Rates of firearm homicide decreased 30% and suicide rates increased 1% since the mid-2000s, but these trends varied substantially by county. Due to a decline in firearm homicides in metropolitan areas, there was no significant difference in these rates between urban and rural counties by 2015. Non Hispanic black men had the highest rate of firearm homicide, but Hispanic men had the greatest number of deaths.Conclusions: We found considerable intrastate variation in firearm mortality in California. Our results will be of interest to researchers, policymakers, and public health practitioners. Similar epidemiologic profiles of firearm mortality are warranted for other states.
