Although the independent effects of childhood adversities and of recent negative events on suicidality have been well-documented, the combinative role of childhood and recent adversities on risk for suicidality is still underexplored, especially in the context of Chinese culture and in consideration of specific types of negative events.
5989 students, randomly sampled from six universities in central China, completed the online survey for this study. Suicidal behavior, life adversity during childhood and stressful events in recent school life were assessed with designed questionnaires.
Students experiencing recent stressful life events more often reported an experience of life adversity during childhood. While recent stressful life events and childhood life adversity both were associated with an increased risk for suicidal behavior, the two exposures presented conjunctively and acted interactively to increase the risk. There was noticeable variation of effects associated with specific childhood life adversities, and sexual abuse, poor parental relationship, divorce of parents and loss of a parent were among the adversities associated with the highest increased risk. Recent conflicts with classmates, poor school performance and rupture of romantic relationships were the recent school life stressors associated with the highest increased risk.
Childhood adversity and recent school life stressors had a combinative role in predicting suicidality of young people studying in Chinese colleges. Unhappy family life during childhood and recent interpersonal conflicts in school were the most important predictors of suicidality in this population.
尽管童年逆境和近期负面事件对自杀倾向的独立影响已有充分记录，但童年逆境与近期逆境对自杀风险的综合作用仍未得到充分研究，尤其是在中国文化背景下以及考虑到特定类型的负面事件时。
从中国中部六所大学随机抽取5989名学生，完成本研究的在线调查。使用设计好的问卷评估自杀行为、童年时期的生活逆境以及近期学校生活中的压力事件。
经历近期压力生活事件的学生更常报告童年时期有生活逆境经历。虽然近期压力生活事件和童年生活逆境均与自杀行为风险增加相关，但这两种暴露因素共同且相互作用地增加了风险。与特定童年生活逆境相关的影响存在显著差异，性虐待、亲子关系不佳、父母离异和失去双亲是风险增加最高的逆境因素。近期与同学的冲突、学业成绩差和恋爱关系破裂是近期学校生活中与风险增加最高相关的压力源。
童年逆境和近期学校生活压力源在预测中国大学生的自杀倾向方面具有综合作用。童年时期不幸福的家庭生活和近期学校中的人际冲突是该人群自杀倾向最重要的预测因素。
