我国城市学龄儿童青少年伤害现状及特征

Status and traits of injury among school children and adolescents in the city of China

目的分析我国近10年城市学龄儿童青少年伤害发生的现状及特征，为有效预防提供依据。方法采用Meta分析方法，根据文献检索策略及纳入、排除标准，检索中国相关生物医学数据库，并结合文献追溯，收集2002年1月-2012年12月过去10年间公开发表有关我国城市学龄儿童青少年伤害现状的研究文献。应用Stata11．0软件进行系统分析。结果最终符合纳入标准的文献有33篇，涉及总样本量146757人，男女比例为1．02：1。Meta分析显示，我国城市学龄儿童青少年伤害人数发生率为29％（95％CI：24．5％～34．3％），人次发生率为53．2％（95％CI：41．7％～67．9％）。跌落伤为首位原因，而交通伤害则倾向于在同一个体身上重复发生。男生伤害人数发生率（35．1％）高于女生（27．6％），中学生伤害人数发生率（31．2％）略高于小学生（30．1%）（P〉0．05）。结论我国城市学龄儿童青少年伤害现状严峻，建议完善符合我国国情的伤害预防监测和干预机制。

Objective To analyze the status and relevant traits of injury among school children and adolescents in the urban areas of China over the past decade and provide the evidence-based strategy. Methods A Meta-analysis was undertaken to comprehensively review the injury of Chinese school children and adolescents based on set criteria. Relevant data published from Jan. 2002 to Dec. 2012 in Chinese electronic databases were identified and retrieved using Stata Version 11.0. Results Thirty-three studies were identified. The overall estimated injury number of people and person time were 2900 （95%CI：24.5%-34. 3%） and 53.2% （95%CI：41.7%-67.9%） respectively. The injuries caused by falling were at the top-one,moreover the road injuries showed a phenomenon of occurring repeatedly. There was difference by the gender and the grade but did not find statistic significance （P〉0.05）. Conclusions The incidence of injuries among school children and adolescents is increasing over the past decade in China. Efficacious monitoring and intervention strategies need to be strengthened.
