Abstract: Objective To offer basic data to prevent the unintentional injuries through conducted a systematic evaluation of unintentional-injury mortality among 0~14-year-old rural children in China. Methods Studies published between 1990 and 2012 which consisting of unintentional-injury mortality were searched from CNKI,Weipu,Wanfang,Medline and Google Scholar databases.The pooled mortality was estimated using Meta-analysis.Subgroup analysis was undertaken by gender.Sensitivity analysis was also performed. Results Six valid papers were included for Meta-analysis,with a total sample size of 8 691 760.The pooled unintentional-injury mortality was 25.92 per 100 thousand (95%CI=19.33 to 32.51 per 100 thousand).Moreover,boys had significant higher unintentional-injury mortality (33.29 per 100 thousand) than girls (18.20 per 100 thousand).Sensitivity analysis suggested that the range of mortality changed little. Conclusion The unintentional-injury mortality among 0~14-year-old rural children in China is in high level,and rural boys are the major population for unintentional injury prevention owing to the significant gender difference.

摘要： 目的 综合评价近20余年来我国0~14岁农村儿童意外伤害死亡率的情况,为预防农村儿童意外伤害提供基础资料和依据。 方法 系统检索中国期刊全文数据库(China National Knowledge Infrastructure,CNKI)、维普、万方数据库和Medline、Google Scholar中1990-2012年发表的、有关中国0~14岁农村儿童意外伤害死亡率的研究文献,采用Meta分析合并估计意外伤害的死亡率,按照性别进行亚组分析,并做敏感性分析。 结果 共纳入合格文献6篇,总样本量为8 691 760人,农村儿童意外伤害死亡2 166人,意外伤害死亡率为25.92/10万,95%CI:19.33/10万~32.51/10万。亚组分析显示,农村男童意外伤害死亡率(33.29/10万)高于女童(18.20/10万),差异明显。经敏感性分析,结果改变不大。 结论 我国0~14岁农村儿童意外伤害死亡率处于较高水平,且存在明显性别差异,农村男童应该是意外伤害预防的重点人群。
