目的 了解中国因伤害导致残疾的流行病学现况.方法 利用2006年第二次全国残疾人抽样调查数据,提取因伤害导致残疾的数据资料进行统计描述与分析,采用聚类分析进行地区间比较.结果 全国因伤害导致残疾的现患率为99.68/万,占总体残疾人的15.59%.残疾类别以肢体残疾最高（65.59%）,其次是听力残疾（23.35%）、智力残疾（4.86%）、视力残疾（4.71%）和言语残疾（1.49%）.残疾等级以四级、三级为主,分别占到55.14%和25.83%.因伤害导致残疾的现患率在不同年龄组问差异有统计学意义（x2=23 106.14,P＜0.001）,年龄越高,因伤害导致残疾的现患率越高.男性高于女性（128.35/万和70.23/万;x2=2161.74,P＜0.001）.聚类分析将全国31个省因伤害导致总残疾的现患率分为5类,其中第5类地区（四川）与第4类地区（湖南、重庆、贵州、宁夏）因伤害导致的残疾问题突出.结论 我国因伤害导致残疾人群发生率约为1000/10万.因伤害导致残疾的类别中以肢体残疾和听力残疾为主.高龄、男性的因伤害导致残疾危险增高,不同地区因伤害导致残疾情况不同.

英文摘要：

Objective To describe and analyze the prevalence and epidemiological features of people with disability caused by injury in the Chinese population, and to provide scientific basis for developing the prevention and control programs on injuries. Methods Statistics and infervention measures were used to analyze the data from the Second China National Sample Survey on injury-caused Disability. Cluster analysis was used to analyze the differences in regions. Results The overall prevalence of disability caused by injury was 99.68/10 000 which occupied 15.59% of all the disability, with multiple disability excluded. Physical disability and hearing disability accounted for 65.59% and 23.35% of all the injury-caused disability respectively, while those ranked Grade Ⅳ and Ⅲ making up the majority（55.14% and 25.83%）of the disability, respectively. There were significant differences in the distribution of injury-caused disability among different age groups（x2= 23 106.14,P〈0.001）and gender（x2=2161.74, P〈0.001）. Ageing and being males having a higher risk on injury- caused disability. Five clusters were identified by cluster analysis, in which injury-caused disability were severe in the fifth（Sichuan province）and the fourth clusters（Hunan, Chongqing,Guizhou, Ningxia province）. Conclusion Problems discovered by injury-caused disability in the Chinese population should not be ignored. Both physical and hearing disabilities appeared to be the two main types of disability while age, gender and region were related to injury-caused disability.Targeted strategies should be developed to decrease the injury-caused disability in China.
