摘要:
系统评价中国大学生非自杀性自伤的检出率及其分布特征,为了解我国大学生NSSI检出率的分布情况提供更可靠的信息.方法 计算机检索PubMed、CNKI、万方数据库和VIP数据库,搜集关于我国大学生非自杀性自伤检出率研究的文献,检索时限为1989年1月至2015年8月.英文检索词包括undergraduate/college/university;self-injury/self-harm/self-mutilation/self-abuse/autolesion/autotomy/autosadism等,中文检索词包括大学生/大学/高校、自(我)伤(害)/自残/自虐.由2名研究者独立进行文献筛选、资料提取和评价纳入研究的偏倚风险后,采用CMA 2.0软件进行Me-ta分析.结果 共纳入23个研究,总样本量73 677人,非自杀性自伤检出率为16.6%(95%CI=10.7%~24.7%).亚组分析显示,中国大学生非自杀性自伤检出率男生(16.2%)低于女生(17.8%),差异有统计学意义(X2=18.609,P<0.01);东部、中部、西部地区高校大学生非自杀性自伤检出率分别为21.9%,23.0%,2.1%,差异有统计学意义(x2=9 373.879,P<0.01).敏感性分析显示,文献质量对结果改变不大.结论 中国大学生非自杀性自伤检出率较高,且在性别、研究地区间存在一定差异.
Abstract:
Objective To systematically review the epidemiology and distribution characteristics of non-suicidal self-injury (NSSI) among undergraduates in China.Methods PubMed,CNKI,Wanfang and VIP databases was used to collect studies related to NSSI among college students in China from January 1989 to August 2015.Two reviewers screened literature,extracted data and evaluated the risk of bias of included studies,and then meta-analysis was performed by using CMA 2 software.Results A total of 23 studies were included,with 73 677 individuals.The report rate of NSSI was 16.6% [95%CI(10.7%-24.7%)].Subgroup analysis showed that the report rate of NSSI among male college students in China (16.2%) was lower than that of female (17.8%),the difference was statistically significant(P<0.01).Report rate of NSSI among college students in the eastern,central and western regions in China was 21.9%,23.0% and 2.1%,respectively,with statistically significant differences(P<0.01).Sensitivity analysis detected that the quality of the literature had a little effect on the results.Conclusion The detection rate of non-suicidal self-injury among college students in China was higher with significant gender and regional characteristics.
