2003—2007年广州市居民意外死亡情况调查分析

目的了解广州市2003—2007年居民意外死亡情况。方法从广州市卫生局死亡监测中心获取广州市居民2003—2007年4873例死亡个案资料,观察不同人群意外死亡的发生率和原因,采用Poisson回归分析意外死亡随时间的变化趋势。结果 2003—2007年广州市居民意外死亡率每年平均下降7.6%。男性意外死亡率明显高于女性。意外死亡的发生率随年龄呈J型分布,但随年龄增长呈现不对称的抛物线形。交通事故、自杀、中毒、坠落、溺水、他杀是最为常见的意外死因,但不同人群死因分布有所差异。结论意外死亡率逐年下降说明意外死亡是可防可控的,不同人群意外死亡的发生率和死因存在差异,应针对不同人群采取相应的干预措施,以最大限度地降低意外死亡率。

Inquisition and Analysis of Accidental Deaths Situation in Guangzhou (2003-2007)

Objective To learn accidental deaths in Guangzhou from 2003 to 2007. Methods All individual data of 4873 cases of accidental deaths from 2003 to 2007 in Guangzhou was provided by Health Bureau of Guangzhou. Accidental mortality rates and death causes were observed, and tendency with time-variation in accidental deaths was analyzed by Poisson regression model. Results The unintentional mortality rates significantly declined from 2003 to 2007 with a average decrease of 7.6%/one year. The unintentional mortality rate in male was much higher than that in female. The death rate with ages was J-shaped, and was asymmetric parabolic with age increase. The frequent causes were traffic accidents, suicides, poisoning, accidental falls, drowning and murder. The causes distribution of accidental deaths may differ with age groups. Conclusion The accidental mortality rates decreased over the past years, which may indicate that accidental mortality is preventable and avoidable. The rates and causes of accidental mortality differ by different crowds, various interventions should target different crowd to minimize the possibility of accidental mortality.
