To describe rates and trends in the incidence of non-fatal and fatal firearm assault among children (16 years old or younger) over an 11 year period in Chicago, Illinois and to identify the socioeconomic characteristics of community areas where assaults are common.
The Chicago Police Department (CPD) records from 1986 through 1996 were reviewed for children assaulted with a firearm. United States census data for 1990 for Chicago were used to calculate incidence rates; census data were also used for community area (defined by census tract) socioeconomic descriptions.
The CPD recorded 11,163 pediatric firearm assaults during the study period: 10,571 non-fatal and 592 (5%) fatal. From 1986 through 1996 non-fatal assaults more than doubled, with the highest rates in 1994; fatal assaults tripled, with rates peaking in 1993-94. Significant increases in non-fatal firearm assaults occurred among black and Hispanic males and females. In 1994, compared with white males, the relative risk of non-fatal assault was 7.0 (95% confidence interval (CI) 5.3 to 9.1) for black males and 3.3 (95% CI 2.5 to 4.4) for Hispanic males; the relative risk was 1.5 (95% CI 1.1 to 2.1) for black females. A handgun was the firearm used in most assaults (88% of non-fatal and 84% of fatal). Within community areas, the correlation between non-fatal and fatal assault incidence was strong (r=0.80, p<0.001). The proportion of families with income below the 1989 poverty level ($12,674) and the per cent black race in the community area together accounted for 70% of the variance in assault rates.
From 1986 to 1994 there were significant increases in both non-fatal and fatal firearm assaults, usually by handguns; thereafter, rates declined. Urban children who were victims of non-fatal firearm assault appear to come from the same population as those who suffer fatal assaults. Black and Hispanic youth living in poverty were at particular risk.
描述伊利诺伊州芝加哥市11年间16岁及以下儿童非致命和致命枪支袭击的发生率及趋势,并确定袭击事件频发的社区区域的社会经济特征。
查阅了芝加哥警察局(CPD)1986年至1996年期间儿童遭受枪支袭击的记录。使用1990年美国芝加哥的人口普查数据计算发病率;普查数据也用于社区区域(由普查区定义)的社会经济描述。
在研究期间,CPD记录了11163起儿童枪支袭击事件:10571起非致命事件和592起(5%)致命事件。从1986年到1996年,非致命袭击事件增加了一倍多,1994年发生率最高;致命袭击事件增加了两倍,发生率在1993 - 1994年达到峰值。非致命枪支袭击事件在黑人及西班牙裔男性和女性中显著增加。1994年,与白人男性相比,黑人男性非致命袭击的相对风险为7.0(95%置信区间(CI)5.3至9.1),西班牙裔男性为3.3(95%CI 2.5至4.4);黑人女性的相对风险为1.5(95%CI 1.1至2.1)。大多数袭击事件中使用的枪支是手枪(非致命袭击事件的88%,致命袭击事件的84%)。在社区区域内,非致命和致命袭击发生率之间的相关性很强(r = 0.80,p < 0.001)。收入低于1989年贫困线(12674美元)的家庭比例以及社区区域内黑人种族的百分比共同占袭击发生率差异的70%。
从1986年到1994年,非致命和致命枪支袭击事件均显著增加,通常是手枪袭击;此后,发生率下降。非致命枪支袭击事件的城市儿童受害者似乎与致命袭击事件的受害者来自同一人群。生活在贫困中的黑人和西班牙裔青年面临特别的风险
