目的运用Meta分析综合评价2000-2012年中国中学生自杀意念发生情况,并分析其在性别和年级间的差别,为中学生自杀干预提供理论依据.方法系统检索PubMed、万方数据库、维普信息资源系统、中国期刊全文数据库及中国生物医学文献数据库,收集所有关于中国中学生自杀意念发生率的研究文献.资料进行异质性检验,以确定采用固定模型或随机模型进行合并分析,采用秩相关检验法进行发表偏倚的评估,并对性别和年级进行亚组分析.结果共入选相关文献40篇,总样本量为320 375人,总自杀意念发生率为17.99％ (95％ CI:16.59％～19.49％).将自杀意念发生率按照性别和年级分层分析,男、女生自杀意念发生率分别为14.71％(95％CI:13.42％～16.11％)和19.92％(95％ CI:19.30％～ 21.64％),差异有统计学意义(P＜0.05)；初中生和高中生自杀意念发生率分别为16.94％ (95％ CI:15.35％～18.66％)和19.01％(95％CI:17.23％～ 20.93％),差异有统计学意义(P＜0.05).结论中国中学生不同性别和年级间自杀意念发生率存在差别.
