Little is known about risk factors of suicidal behavior among Chinese adolescents. This study examined the associations between negative life events, psychopathology, and suicidal behavior in rural adolescents of China.
A total of 1362 adolescent students in a rural prefecture of China completed a self-administered questionnaire concerning suicidal behavior, psychopathology, life events, and demographics. Data analyses were conducted using multivariate logistic regression modeling.
Females were more likely to report suicidal ideation than males (22.0% vs. 17.5%). While the rate of suicide attempt was slightly higher in younger males (12-15 years) than in females (4.7% vs. 3.1%), the rate was higher in older females (16-18 years) than in males (12.7% vs. 9.5%). Suicide attempters reported more negative life events during the past year than suicidal ideators and non-suicidal adolescents. Academic stress and family conflicts were the major stress domains of adolescents at risk for suicidal behavior. A significant dose-response relationship was observed between the number of life events and suicidal behavior. Negative life events were also associated with increased risk for internalizing and externalizing problems. Both internalizing and externalizing problems were significantly associated with elevated risk for suicidal behavior after negative life events were controlled.
This is a cross-sectional study. Longitudinal study is warranted to examine the roles of life stress in adolescent suicidal behavior.
Adolescents who experienced more negative life events are at increased risk for suicidal behavior. Both internalizing and externalizing problems mediate the effect of life events on adolescent suicidal behavior.
关于中国青少年自杀行为的风险因素，人们了解甚少。本研究探讨了中国农村青少年中负面生活事件、精神病理学与自杀行为之间的关联。
中国一个农村地区的1362名青少年学生完成了一份关于自杀行为、精神病理学、生活事件和人口统计学的自填问卷。采用多因素逻辑回归模型进行数据分析。
女性比男性更有可能报告有自杀意念（22.0%对17.5%）。虽然较年轻男性（12 - 15岁）的自杀未遂率略高于女性（4.7%对3.1%），但年龄较大女性（16 - 18岁）的自杀未遂率高于男性（12.7%对9.5%）。自杀未遂者报告在过去一年中经历的负面生活事件比有自杀意念者和无自杀行为的青少年更多。学业压力和家庭冲突是有自杀行为风险的青少年的主要压力领域。观察到生活事件数量与自杀行为之间存在显著的剂量反应关系。负面生活事件还与内化和外化问题风险增加有关。在控制负面生活事件后，内化和外化问题均与自杀行为风险升高显著相关。
这是一项横断面研究。需要进行纵向研究以检验生活压力在青少年自杀行为中的作用。
经历更多负面生活事件的青少年自杀行为风险增加。内化和外化问题均介导了生活事件对青少年自杀行为的影响。
