This population-based cross-sectional study describes self-harm (SH) behaviors and associated factors in 2898 Chinese left-behind children (LBC).
Descriptive statistics were used to present and compare the distributional characteristics of SH behaviors. Binary and ordinal logistic-regression models for survey data were applied to explore associated factors of SH.
Among the LBC, 48% (95% CI: 42%-54%) reported SH behaviors. SH was prominently associated with suicidal ideation. Boys, junior high-school students, and LBC whose fathers were poorly educated were observed to have higher prevalence of SH. Boys, local ethnic minorities, junior high-school students, and LBC whose fathers were comparatively well educated were observed to be at increased risk of more medically serious SH behaviors.
SH is a substantial public health problem among rural Chinese LBC. Targeted intervention measures should be developed to reduce future suicide risk.
本基于人群的横断面研究描述了 2898 名中国留守儿童（LBC）中的自伤（SH）行为及其相关因素。
采用描述性统计方法展示和比较 SH 行为的分布特征。采用二项逻辑回归和有序逻辑回归模型对调查数据进行分析，以探讨 SH 的相关因素。
在所调查的 LBC 中，有 48%（95%CI：42%-54%）报告存在 SH 行为。SH 与自杀意念显著相关。男孩、初中生和父亲文化程度较低的 LBC 中 SH 的发生率更高。男孩、本地少数民族、初中生和父亲文化程度较高的 LBC 中，更严重的 SH 行为的风险更高。
SH 是中国农村留守儿童面临的一个严重的公共卫生问题。应制定有针对性的干预措施，以降低未来的自杀风险。
