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.
