To analyze the prevalence and differences between gender and grades of suicide ideation among middle school students in China from 2000 to 2012 so as to provide basis for suicide prevention among middle school students.
Electronic search strategy was carried out, using PubMed, Wanfang Database, VIP Database, China National Knowledge Infrastructure (CNKI) and CBM to collect data on suicide ideation among middle school students. Fixed effects model or random effects model was employed according to statistical tests for the homogeneity. Publication bias was assessed by rank correlation test.
40 papers were included for meta-analysis, with a total sample size of 320 375. The combined prevalence of suicide ideation was 17.99% (95%CI: 16.59% - 19.49%). Prevalence rates of suicide ideation were stratified by factors as gender and grade at school. Pooled prevalence rates on suicide ideation were as follows: 14.71% (95%CI: 13.42% - 16.11%) and 19.92% (95%CI: 19.30% - 21.64%), P < 0.05 for boys and girls;16.94% (95%CI: 15.35% - 18.66%) and 19.01% (95%CI: 17.23% - 20.93%), P < 0.05 for senior or junior high school students, respectively.
There were differences in the prevalence of suicide ideation among middle school students between genders and grades in China.
分析2000年至2012年中国中学生自杀意念的发生率及其性别和年级差异,为中学生自杀预防提供依据。
采用电子检索策略,通过PubMed、万方数据库、维普数据库、中国知网(CNKI)和中国生物医学文献数据库(CBM)收集有关中学生自杀意念的数据。根据同质性统计检验采用固定效应模型或随机效应模型。采用秩相关检验评估发表偏倚。
纳入40篇文献进行荟萃分析,总样本量为320375。自杀意念的合并发生率为17.99%(95%CI:16.59% - 19.49%)。自杀意念发生率按性别和年级进行分层。自杀意念的合并发生率如下:男生为14.71%(95%CI:13.42% - 16.11%),女生为19.92%(95%CI:19.30% - 21.64%),P<0.05;高中生为16.94%(95%CI:15.35% - 18.66%),初中生为19.01%(95%CI:17.23% - 20.93%),P<0.05。
中国中学生自杀意念发生率在性别和年级上存在差异。
