Homicide disproportionately affects persons aged 10-24 years in the United States and consistently ranks in the top three leading causes of death in this age group, resulting in approximately 4,800 deaths and an estimated $9 billion in lost productivity and medical costs in 2010. To investigate trends in homicide among persons aged 10-24 years for the period 1981-2010, CDC analyzed National Vital Statistics System data on deaths caused by homicide of persons in this age group and examined trends by sex, age, race/ethnicity, and mechanism of injury. This report describes the results of that analysis, which indicated that homicide rates varied substantially during the study period, with a sharp rise from 1985 to 1993 followed by a decline that has slowed since 1999. During the period 2000-2010, rates declined for all groups, although the decline was significantly slower for males compared with females and for blacks compared with Hispanics and persons of other racial/ethnic groups. By mechanism of injury, the decline for firearm homicides from 2000 to 2010 was significantly slower than for nonfirearm homicides. The homicide rate among persons aged 10-24 years in 2010 was 7.5 per 100,000, the lowest in the 30-year study period. Primary prevention strategies remain critical, particularly among groups at increased risk for homicide.
在美国,凶杀事件不成比例地影响 10-24 岁的人群,且一直位列该年龄段前三大主要死因,导致 2010 年约有 4800 人死亡,并估计损失 90 亿美元的生产力和医疗费用。为了调查 1981-2010 年间 10-24 岁人群凶杀事件的趋势,CDC 分析了国家生命统计系统关于该年龄段人群因凶杀而死亡的数据,并按性别、年龄、种族和受伤机制对趋势进行了检查。本报告介绍了该分析的结果,结果表明,在研究期间,凶杀率差异很大,1985 年至 1993 年急剧上升,之后自 1999 年以来下降速度放缓。在 2000-2010 年期间,所有人群的凶杀率都有所下降,尽管与女性相比,男性和与西班牙裔以及其他种族/族裔群体相比,黑人的下降速度明显较慢。按受伤机制,2000 年至 2010 年枪支凶杀的下降速度明显慢于非枪支凶杀。2010 年,10-24 岁人群的凶杀率为每 10 万人 7.5 人,是 30 年研究期间的最低水平。初级预防策略仍然至关重要,尤其是对处于凶杀高风险的群体。
