Leading causes of unintentional and intentional injury mortality: United States, 2000-2009.

We have described national trends for the 5 leading external causes of injury mortality. We used negative binomial regression and annual underlying cause-of-death data for US residents for 2000 through 2009. Mortality rates for unintentional poisoning, unintentional falls, and suicide increased by 128%, 71%, and 15%, respectively. The unintentional motor vehicle traffic crash mortality rate declined 25%. Suicide ranked first as a cause of injury mortality, followed by motor vehicle traffic crashes, poisoning, falls, and homicide. Females had a lower injury mortality rate than did males. The adjusted fall mortality rate displayed a positive age gradient. Blacks and Hispanics had lower adjusted motor vehicle traffic crash and suicide mortality rates and higher adjusted homicide rates than did Whites, and a lower unadjusted total injury mortality rate. Mortality rates for suicide, poisoning, and falls rose substantially over the past decade. Suicide has surpassed motor vehicle traffic crashes as the leading cause of injury mortality. Comprehensive traffic safety measures have successfully reduced the national motor vehicle traffic crash mortality rate. Similar efforts will be required to diminish the burden of other injury.

我们描述了导致伤害死亡的5大主要外部原因的全国趋势。我们使用负二项回归以及2000年至2009年美国居民的年度根本死因数据。意外中毒、意外跌倒和自杀的死亡率分别上升了128%、71%和15%。意外机动车交通事故死亡率下降了25%。自杀作为伤害死亡的原因排名第一，其次是机动车交通事故、中毒、跌倒和他杀。女性的伤害死亡率低于男性。调整后的跌倒死亡率呈现出正的年龄梯度。黑人和西班牙裔调整后的机动车交通事故和自杀死亡率低于白人，调整后的他杀率高于白人，且未调整的总伤害死亡率较低。在过去十年中，自杀、中毒和跌倒的死亡率大幅上升。自杀已超过机动车交通事故，成为伤害死亡的首要原因。全面的交通安全措施已成功降低了全国机动车交通事故死亡率。要减轻其他伤害的负担，也需要类似的努力。
