Increasing evidence has shown an increased risk of non-suicidal self-injury (NSSI) in left-behind children and adolescents (LBCAs). However, a systematic summary of studies comparing the risk of NSSI between LBCAs and non-LBCAs in China is lacking.
To investigate the risk of NSSI among LBCAs in China.
We performed a systematic search of Embase, PubMed, and Web of Science from initiation to October 25, 2024, for all relevant studies of NSSI and LBCAs. The effect sizes were reported as odds ratios (ORs) with 95% confidence intervals (CI). Sensitivity analyses were conducted to further confirm the stability of the findings.
A total of 10 studies with 165276 children and adolescents were included in this study. LBCAs had significantly higher rates of NSSI compared with non-LBCAs (OR = 1.33, 95%CI: 1.19-1.49), with high heterogeneity observed ( = 77%, < 0.001). Further sensitivity analyses were consistent with the primary analysis (OR = 1.29, 95%CI: 1.21-1.39, = 0%).
LBCAs are found to be at an increased risk of NSSI compared with children and adolescents of non-migrants. More attention and intervention are urgently needed for LBCAs, especially those living in developing countries.
越来越多的证据表明，留守儿童和青少年（LBCA）出现非自杀性自伤（NSSI）的风险增加。然而，在中国，缺乏对比较留守儿童和非留守儿童NSSI风险的研究进行系统总结。
调查中国留守儿童非自杀性自伤的风险。
我们对Embase、PubMed和Web of Science进行了系统检索，检索时间从数据库建立至2024年10月25日，以查找所有关于非自杀性自伤和留守儿童的相关研究。效应量以比值比（OR）及95%置信区间（CI）表示。进行敏感性分析以进一步确认研究结果的稳定性。
本研究共纳入10项研究，涉及165276名儿童和青少年。与非留守儿童相比，留守儿童的非自杀性自伤发生率显著更高（OR = 1.33，95%CI：1.19 - 1.49），观察到高异质性（I² = 77%，P < 0.001）。进一步的敏感性分析与初步分析结果一致（OR = 1.29，95%CI：1.21 - 1.39，I² = 0%）。
与非流动儿童和青少年相比，发现留守儿童非自杀性自伤的风险增加。迫切需要对留守儿童，尤其是生活在发展中国家的留守儿童给予更多关注和干预。
