美国的自杀率在1981年至1986年间上升了6%，在1986年至1999年间下降了18%。对自杀的最新趋势缺乏详细的描述，特别是关于自杀的方法。近年来（1999-2005），特定人群自杀率的主要变化需要信息：死亡率数据来自基于Web的伤害统计查询和报告系统。1981年至2005年期间的自杀趋势按年龄、种族、性别和方法进行了分析，重点是1999年至2005年期间的增加。线性回归被用来检验自杀死亡率趋势的意义。自杀死亡率的年度百分比变化被用来衡量自杀死亡率的线性趋势。自杀率在1999年后上升，主要是由于40-64岁的白人自杀率上升，1999年至2005年期间，男性自杀率每年上升2.7%，女性自杀率每年上升3.9%。上吊/窒息死亡率分别上升了6.3%和2.3%，中毒死亡率分别上升了2.8%和19.3%，枪支死亡率分别上升了1.5%和1.9%。其他年龄或种族组的自杀率没有增加。结论：年龄、种族、性别和方法的差异增加强调了自杀流行病学的变化。40-64岁的白人最近成为自杀的新的高风险群体。虽然火器仍然是最常见的自杀方法，但男性上吊/窒息自杀和女性中毒自杀的显著增加值得注意。
Background: The overall suicide rate in the U.S. increased by 6% between 1981 and 1986 and declined by 18% between 1986 and 1999. Detailed descriptions of recent trends in suicide are lacking, especially with regard to the method of suicide. Information is needed on the major changes in rates Of suicide in specific population groups in recent years (1999-2005).Methods: Mortality data came from the Web-based Injury Statistics Query and Reporting System. Suicide trends during 1981-2005 were analyzed by age, race, gender, and method, with an emphasis on increases between 1999 and 2005. Linear regression was used to examine the significance of trends in suicide mortality. The annual percentage change in rates was employed to measure the linear trend in suicide mortality.Results: The suicide rate increased after 1999, due primarily to an increase in suicide among whites aged 40-64 years, whose rate of completed suicide between 1999 and 2005 rose by 2.7% annually for men and by 3.9% annually for women, with increases of 6.3% and 2.3% for hanging/suffocation, 2.8% and 19.3% for poisoning, and 1.5% and 1.9% for firearms for trien and women, respectively. Rates did not increase for other age or racial groups.Conclusions: The differential increases by age, race, gender, and method underscore a change in the epidemiology of suicide. Whites aged 40-64 years have recently emerged as a new high-risk group for suicide. Although firearms remain the most common method of suicide, the notable increases in suicide by hanging/suffocation in men and by poisoning in women deserve preventive attention.
