abstract="<b>Objective:</b> Non-suicidal self-injury (NSSI) in adolescents appeared prevalent and multifactorial. This study was to examine the associations between exposure to suicidal behaviors and NSSI in the Chinese adolescents. <b>Methods:</b> Participants included for analyses were 5 154 adolescent students who participated in the baseline survey in 2015 and the first follow-up survey in 2016 of the Shandong Adolescent Behavior and Health Cohort, but with no history of NSSI at the baseline survey. A self-administered structured questionnaire was used to collect data on demographics, behavioral and emotional problems, lifetime and last-year NSSI. Data on the history of exposure to suicide attempt or death of a family member, friend, or close acquaintance were also collected. Multivariate logistic regression methods were used to examine the associations between exposure to suicidal behaviors and NSSI. <b>Results:</b> In the baseline survey, mean age of the 5 154 participants was (14.49±1.48) years, with 48.5<i>%</i> of the participants as girls. Of the participants, 9.0<i>%</i> reported having been exposed to suicidal behaviors, including 6.0<i>%</i> reported to suicide attempt, 4.9<i>%</i> to suicide death, 7.3<i>%</i> to suicidal behaviors of friends/close acquaintances, and 3.1<i>%</i> to suicidal behaviors of relatives. The prevalence rates of NSSI in the last year were significantly higher in adolescents who had been exposed to suicidal behaviors than those who had not (<i>P</i><0.05). <br><br>RESULTS from the multivariate logistic regressions showed that exposure to suicide death (<i>OR</i>=1.91, 95<i>%CI</i>: 1.22-3.01) or to suicidal behaviors of relatives (<i>OR</i>=1.79, 95<i>%CI</i>: 1.02-3.12) were both significantly associated with the increased risk of NSSI. <b>Conclusions:</b> Experiences related to exposure to suicide-death or suicidal behaviors of relatives were associated with increased risk of NSSI in adolescents. After the suicide events, psychological counseling and health education programs set for high-risk groups were helpful in promoting physical and mental health and preventing the attempt of self-injury in teenagers.<p /> <p>Language: zh</p> <b>目的：</b> 青少年群体中，非自杀性自伤（non-suicidal self-injury，NSSI）行为较为普遍且受多种因素影响。本研究旨在探究中国青少年自杀行为暴露与其自身NSSI之间的关系。 <b>方法：</b> 研究对象来自山东省青少年行为与健康队列研究。选取参与了2015年基线调查和2016年第一次随访调查，并且基线调查中不存在NSSI行为史的5 154名学生为研究对象。研究内容通过自填式问卷收集，包括基本人口学信息、社会心理学信息、终生及过去一年NSSI情况、自杀行为暴露史等。采用多因素logistic回归模型分析基线自杀行为暴露与一年后NSSI间的关系。 <b>结果：</b> 5 154名研究对象的基线年龄为（14.49±1.48）岁，女性占48.5<i>%</i>。9.0<i>%</i>的青少年报告曾暴露于自杀行为，其中6.0<i>%</i>暴露于自杀未遂，4.9<i>%</i>暴露于自杀死亡，7.3<i>%</i>暴露于朋友/熟人的自杀行为，3.1<i>%</i>暴露于亲属的自杀行为。自杀行为暴露组的过去一年NSSI发生率高于非暴露组，差异有统计学意义（<i>P</i><0.05）。多因素logistic回归分析显示，与非暴露组相比，暴露于自杀死亡（<i>OR</i>=1.91，95<i>%CI</i>：1.22~3.01）和暴露于亲属自杀行为（<i>OR</i>=1.79，95<i>%CI</i>：1.02~3.12）与NSSI风险增加有关。 <b>结论：</b> 暴露于自杀死亡或亲属自杀行为可能会增加青少年NSSI行为风险。自杀事件发生后，针对高危人群进行心理疏导和健康教育可促进青少年身心健康、预防自我伤害。.<p /> <p>Language: zh</p>",
