Abstract: Objective To comprehensive evaluat traffic injuries incidence among children and adolescents in China from 2002 to 2012 using the method of Meta-analysis,and provide evidence for preventing traffic injuries. Methods CNKI、WangFang database,CBM,VIP and PubMed database were searched to collect the studies that were included between 2002 and 2012 about the traffic injuries incidence among children and adolescents in China.The pooled incidence was estimated using Meta-analysis and analyzed the differences between sex,urban/rural,research region and injury standards,Sensitivity analysis and Publication bias were performed. Results Strict accordance with the inclusion criteria and exclusion criteria,39 studies were selected with a total sample size of 637 330.The pooled incidence of traffic injuries was 1.38%(95%CI:0.90%~2.12%).Subgroup analysis showed the following results:1.97% and 1.66% for boys and girls,1.26% and 1.32% for urban and rural,1.43% and 0.64% for injury standards of 1996 and 2004,0.94%,2.30% and 2.38% for eastern,central and western region differences were significant (P<0.05) for each group. Conclusion The traffic injuries incidence among children and adolescents has differences in sex,urban/rural,research region and injury standards,we should be put focus on boys,rural and the western to take some measures to protect them.At the same time,it is necessary to further unify injury standards about children and adolescents.

摘要： 目的 采用Meta分析的方法综合评价我国儿童青少年2002-2012年交通伤害发生率的情况,为预防儿童青少年交通伤害提供依据。方法 系统检索中国知网、万方数据库、中国生物医学文献数据库、维普信息资源系统及PubMed数据库,收集2002-2012年收录的有关我国儿童青少年交通伤害发生率的文献,采用Meta分析合并估计交通伤害发生率,按照性别、城/乡、研究地区和伤害标准进行亚组分析,并对结果进行敏感性分析和发表偏倚的评价。结果 严格按照纳入、排除标准,共筛选出39篇,总样本量为637 330人,合并交通伤害发生率:1.38%(95%CI:0.90%~2.12%),亚组分析显示:交通伤害发生率男、女童分别为1.97%、1.66%,城市、农村分别为1.26%、1.32%,1996、2004版伤害标准分别为1.43%、0.64%,东部、中部、西部地区分别为0.94%、2.30%、2.38%,各组之间差异均有统计学意义(P<0.05)。结论 我国儿童青少年交通伤害发生率在性别、城/乡、研究地区和伤害判定标准之间存在差异,应将男童、农村地区以及经济不发达的西部作为交通伤害的重点预防对象,同时有必要进一步统一儿童青少年意外伤害判定标准。
