医学专科学生童年期虐待经历近期生活事件与非自杀性自伤行为的关联

Childhood abuse experiences,recent life events and non-suicidal self-injury among college students

目的了解医学专科大学生非自杀性自伤行为(non-suicidal self-injury,NSSI)现状,分析童年期虐待和近期生活事件对大学生NSSI的影响,为促进大学生身心健康提供参考。方法采用分层整群抽样方法,抽取安徽省某医学专科学校大一、大二年级1 875名学生,调查其童年期虐待、近期生活事件和NSSI等信息,建立多因素Logistic回归模型分析童年期虐待和生活事件对NSSI的影响。结果大学生NSSI的检出率为14.7%,男生(16.1%)高于女生(14.1%),差异无统计学意义(P>0.05)。有童年期虐待经历者NSSI的检出率(17.3%)高于无虐待经历者(11.6%),差异有统计学意义(χ~2=11.992,P<0.01);随近期生活事件水平的升高,大学生NSSI检出率呈增高趋势(χ~2=61.798,P<0.01)。有童年期虐待经历学生中,高水平的生活事件会增加NSSI的发生风险[OR(95%CI)=3.32(1.99~5.53)];无童年期虐待经历学生中,其发生风险亦增加[OR(95%CI)=5.66(2.75~11.68)]。低水平近期生活事件学生中,童年期虐待会增加NSSI风险[(OR(95%CI)=2.52(1.19~5.32)];而在中高水平生活事件学生中,童年期虐待对NSSI的影响无统计学意义。结论童年期虐待和近期生活事件是大学生NSSI的重要影响因素,减少童年期虐待特别是近期生活事件的发生有益于大学生NSSI的防控。

Objective To determine the relationship between childhood abuse,recent life events,and non-suicidal self-injury（ NSSI） among college students. Methods A total of 1 875 students involved freshman and sophomore were recruited from a college. We assessed childhood abuse exposure,life events（ Multidimensional Life Events Rating Questionnaire for Middle School Students,MLERQ）,and the prevalence of NSSI. Logistic regression was used to analyze the relationship between childhood abuse,life events,and non-suicidal self-injury. Results The prevalence of NSSI was 14. 7%,and no gender difference was found（ P〈0. 05）. The rates of NSSI was higher with childhood abuse exposure（ 17.3% vs 11.6%） or more life event（ 24.6% vs 13.8% vs6. 8%）. Among adolescents reporting childhood abuse,those in the highest tertile of life events increased the risk of NSSI than those in the lowest tertile [adjusted prevalence ratio（ 95% confidence interval） = 3.32（ 1.99,5.53） ]; for those reporting no CA,the ratio was 5.66（ 2.75,11.68）. Among students with lowest tertile of life events,those with childhood abuse increased the risk of NSSI [adjusted prevalence ratio（ 95% confidence interval） = 2.52（ 1.19,5.32） ]; for those reporting moderate and highest tertile of life events,the effect of childhood abuse on NSSI were not found. Conclusion Childhood abuse and recent life events are determinants of NSSI among college students. Prevention of childhood abuse,especially recent life events could be used to control the NSSI of adolescents.
