There are an increasing number of studies that discussed suicide ideation (SI), suicide plan (SP), and suicide attempt (SA) among left-behind children (LBC). However, the prevalence of these indicators of LBC has not been synthesized and the true correlation between these indicators and left-behind status remains unclear.
Electronic databases were comprehensively searched, and eligible observational studies were selected to extract useful data. We pooled the rates and their 95% confidence intervals (95% CIs) to determine the prevalence of SI, SP, and SA among LBC. The odds ratios (ORs) and 95% CIs were calculated to reflect the association between left-behind status and risk of SI, SP, and SA.
Among LBC, the pooled prevalence was 18.7% (95% CI: 15.4-21.9) for SI, 6.4% (95% CI: 4.7-8.1) for SP, and 3.1% (95% CI: 2.6-3.6) for SA. Compared to non-LBC, LBC was at higher risk of SI (OR = 1.26), SP (OR = 1.20), and SA (OR = 1.14), but only the effect for SI achieved statistical significance.
Overall, the prevalence of SI, SP, and SA is common among LBC, and parental migration has a significant impact on the SI of LBC. Intervention plans and programs are urgently needed to prevent suicidality of this vulnerable group.
越来越多的研究讨论了留守儿童（LBC）的自杀意念（SI）、自杀计划（SP）和自杀企图（SA）。然而，这些指标在 LBC 中的流行率尚未得到综合，LBC 状态与这些指标之间的真实相关性仍不清楚。
全面检索电子数据库，并选择合格的观察性研究以提取有用数据。我们汇总了比率及其 95%置信区间（95%CI），以确定 LBC 中 SI、SP 和 SA 的流行率。计算比值比（OR）及其 95%CI，以反映 LBC 状态与 SI、SP 和 SA 风险之间的关联。
在 LBC 中，SI 的合并流行率为 18.7%（95%CI：15.4-21.9），SP 为 6.4%（95%CI：4.7-8.1），SA 为 3.1%（95%CI：2.6-3.6）。与非 LBC 相比，LBC 发生 SI（OR=1.26）、SP（OR=1.20）和 SA（OR=1.14）的风险更高，但仅 SI 的影响具有统计学意义。
总体而言，LBC 中 SI、SP 和 SA 的流行率较高，父母迁移对 LBC 的 SI 有重大影响。迫切需要干预计划和方案来预防这一弱势群体的自杀行为。
