Non-suicidal self-injury (NSSI) is a significant predictor of completed suicide and is increasingly recognized as a serious public health concern. Multiple factors, including social, familial, mental, and genetic factors could influence the occurrence of this behavior. Identifying the early risk factors is important for screening and preventing this behavior.
Here, we recruited a total of 742 adolescent inpatient participants from a mental health center and conducted a series of diagnostic interviews and questionnaires to assess NSSI behavior and other events. Bivariate analysis was used to detect differences between groups in NSSI and non-NSSI. Then, binary logistic regression was fitted to identify predictors of NSSI as a function of these questionnaire scores.
Of the 742 adolescents examined, a total of 382 (51.5%) participants engaged in NSSI. Bivariate analysis showed that age, gender, depression, anxiety, insomnia, and childhood trauma was significantly associated with NSSI. Logistic regression results suggested that females had 2.43 higher odds of engaging in NSSI when compared to their male counterparts (OR = 3.43, 95%CI = 2.09-5.74, = 1.70 × 10). Depression was a primary risk predictor for NSSI with each additional increase in symptoms of depression increasing the odds of engaging in NSSI by 18% (OR = 1.18, 95%CI = 1.12-1.25, = 2.25 × 10).
More than half of the adolescent inpatients with psychiatric disorders have NSSI experience. Depression and gender were the risk factors for NSSI. Age at a specific range had a high prevalence of NSSI.
非自杀性自伤（NSSI）是自杀既遂的一个重要预测指标，并且越来越被视为一个严重的公共卫生问题。多种因素，包括社会、家庭、心理和遗传因素，都可能影响这种行为的发生。识别早期风险因素对于筛查和预防这种行为很重要。
在此，我们从一家心理健康中心共招募了742名青少年住院参与者，并进行了一系列诊断性访谈和问卷调查，以评估NSSI行为及其他事件。采用双变量分析来检测NSSI组和非NSSI组之间的差异。然后，拟合二元逻辑回归以确定作为这些问卷分数函数的NSSI预测因素。
在接受检查的742名青少年中，共有382名（51.5%）参与者有NSSI行为。双变量分析表明，年龄、性别、抑郁、焦虑、失眠和童年创伤与NSSI显著相关。逻辑回归结果表明，与男性相比，女性发生NSSI的几率高2.43倍（比值比[OR]=3.43，95%置信区间[CI]=2.09 - 5.74，P = 1.70×10⁻¹⁰）。抑郁是NSSI的主要风险预测因素，抑郁症状每增加一分，发生NSSI的几率增加18%（OR = 1.18，95%CI = 1.12 - 1.25，P = 2.25×10⁻⁹）。
超过一半的患有精神疾病的青少年住院患者有NSSI经历。抑郁和性别是NSSI的风险因素。特定年龄段的NSSI患病率较高。
