中国青少年非自杀性自伤检出率的Meta分析

目的 了解中国青少年非自杀性自伤检出率及其影响因素，为有效降低青少年非自杀性自伤检出率提供参考。方法检索CNKI、VIP、Wan Fang、Springer、Pub Med、Wiley Online library、Science Direct中外文数据库进行检索，检索时限为建库至2022年8月。严格按照纳入及排除标准筛选相关文献进行meta分析。结果 共纳入43篇文献，253 264名被试。Meta分析结果显示，中国青少年非自杀性自伤检出率为21.9%(95%CI:17.9%～26.0%)]。亚组分析结果显示，女性21.6%(95%CI:17.5%～25.6%)]、农村20.5%(95%CI:13.7%～27.3%)]、独生子女21.7%(95%CI:15.9%～27.5%)]、高中生28.2%(95%CI:24.8%～31.7%)]、中部23.5%(95%CI:17.7%～29.3%)]、2015年及之后调查22.5%(95%CI:17.5%～27.4%)]的青少年非自杀性自伤检出率更高。测量工具的检出率存在统计学意义（P<0.001）。结论 青少年非自杀性自伤...

Meta-analysis of the detection rate of non-suicidal self-injury among Chinese adolescents

Objective To investigate the detection rate of non-suicide self-injury among Chinese adolescents and its influencing factors, and to provide reference for effectively reducing the detection rate of non-suicide self-injury among adolescents. Methods Chinese and foreign language databases including CNKI, VIP, WanFang, Springer, PubMed, Wiley Online library, and ScienceDirect were searched, and the search time was until August 2022. According to the inclusion and exclusion criteria, relevant literatures were screened for meta-analysis. Results A total of 43 articles and 253 264 participants were included. The detection rate of non-suicidal self-injury among Chinese adolescents was 21.9% (95%CI: 17.9%-26.0%). Subgroup analysis showed that higher detection rate of non-suicidal self-injury among adolescents was found in those females (21.6%, 95%CI: 17.5%-25.6%), in rural areas (20.5%, 95%CI: 13.7%-27.3%), being the only child (21.7%, 95%CI: 15.9%-27.5%), high school students (28.2%, 95%CI: 24.8%-31.7%), in central China (23.5%, 95%CI: 17.7%-29.3%), and surveyed in and after the year of 2015 (22.5%, 95%CI: 17.5%-27.4%) .The detection rate of measuring instruments was statistically significant (P<0.001). Conclusion The detection rate of non-suicide self-injury among adolescents is high, and there are differences to varying degrees in gender, place of origin, only child, school section, investigation area, measuring instruments, and survey period.
