目的：根据世界卫生组织的统计，每一个自杀者至少有20次自杀企图。在过去十年中，尽管中国对青少年自杀未遂的认识不断提高，但一直没有全面的系统报告生命统计数据。因此，在一些研究中报告的自杀企图的流行程度各不相同。因此，本研究的目的是提供第一个荟萃分析的横断面研究自杀企图，以填补这一空白。方法：两名评价者通过PubMed-Medline、Embase、万方数据独立筛选了可能相关的自杀未遂横断面研究，重庆VIP和中国国家知识基础设施数据库，使用核心术语“自杀未遂”/“自杀未遂”1“自杀未遂”和“自杀未遂”* 在文章标题、摘要和关键词中使用“/”青年“/”儿童“/”学生 *“和”中国“/”中国人“。采用卡方Q检验和I-2统计量评价异质性。森林图用于以图形方式显示结果。通过漏斗图、Begg和Egger检验评估潜在的发表偏倚。结果：共有43项研究（200，124名受试者）符合入选标准。中国青少年自杀未遂的合并患病率为2.94%（95%CI：2.53%-3.41%）。发现患病率估计值存在显著异质性。亚组分析显示，男性自杀未遂发生率为2.50%（95%CI：2.08%~ 3.01%），女性自杀未遂发生率为3.17%（95%CI：2.56%~ 3.91%）。应该制定必要的措施，防止今后发生这种情况。(C)2015 Elsevier Inc.

Objective: According to World Health Organization, for every committed suicide there were 20 suicide attempts at least. In the last decade, despite the increasing awareness on suicide attempts among adolescents in China, there has been no comprehensive system reporting vital statistics. Consequently, the prevalence of suicide attempts reported in some studies ranged variedly. Therefore, the purpose of this study was to provide the first meta-analysis of cross-sectional studies of suicide attempts to fill this gap.Methods: Two reviewers independently screened potentially relevant cross-sectional studies of suicide attempts through PubMed-Medline, Embase, Wanfang Data, Chongqing VIP and Chinese National Knowledge Infrastructure databases using the core terms 'suicid*'/'suicide attempt*'1' attempted suicide' and adolescen*'/' youth' /'child*'/' student*' and 'China'/'Chinese' in the article titles, abstracts and keywords. Chi-square based Q test and I-2 statistic assessed the heterogeneity. Forest plot was used to display results graphically. Potential publication bias was assessed by the funnel plot, Begg's and Egger's test.Results: In total, 43 studies with 200,124 participants met the eligibility criteria. The pooled prevalence of suicide attempts among Chinese adolescents was 2.94% (95% CI: 2.53%-3.41%). Substantial heterogeneity in prevalence estimates was revealed. Subgroup analyses showed that the prevalence for males was 2.50% (95% CI: 2.08%-3.01%), and for females was 3.17% (95% CI: 2.56%-3.91%).Conclusions: In sum, abstracting across the literatures, the prevalence of suicide attempts among Chinese adolescents was moderate compared with other countries around the world. Necessary measures should be set out prevent them in the future. (C) 2015 Elsevier Inc. All rights reserved.
