To examine the association between internet addiction and suicidal behaviors in adolescence and to explore whether the association could be partly or fully accounted by depression or/and behaviors related to the impulsivity.
A total of 3507 urban adolescent students in Hefei were administered to complete the questionnaire concerning interact addiction disorder (IAD), suicidal behaviors during the 12 months preceding the survey, behaviors related to the impulsivity, Center for Epidemiologic Studies Depression Scale and early childhood adversities, respectively. Hierarchical logistic regressions were used to evaluate the associations and possible roles of depression and behaviors related to the impulsivity between internet addition and suicidal behaviors after adjustment for confounding factors.
Of the 3507 participants, 5.2% were diagnosed as IAD, 27.4% reported suicidal ideation during the 12 months preceding the survey, with another 9.5% had a plan and 2.6% had an attempt. Internet addition was associated with suicidal ideation (OR = 1.79, 95%CI: 1.32 - 2.44), plan (OR = 2.32, 95%CI: 1.57 - 3.42), and attempt (OR = 2.08, 95%CI: 1.03 - 4.22). After adjustment for potential confounding factors, the association between internet addition and attempt was insignificant. When depression and behaviors related to the impulsivity were entered into Hierarchical regression respectively, the associations between internet addition, suicidal ideation and plan were substantially reduced. While internet addition was enter into Hierarchical regression, the associations between depression, behaviors related to the impulsivity, suicidal ideation and plan were not reduced.
Adolescent internet addition seems to be associated with suicidal ideation and plan, and the association is possibly mediated by depression and behaviors related to the impulsivity.
探讨青少年网络成瘾与自杀行为之间的关联，并探究这种关联是否能部分或完全由抑郁及/或冲动相关行为来解释。
对合肥市3507名城市青少年学生进行问卷调查，内容分别涉及网络成瘾障碍（IAD）、调查前12个月内的自杀行为、冲动相关行为、流行病学研究中心抑郁量表以及童年期逆境。采用分层逻辑回归分析，在调整混杂因素后评估抑郁及冲动相关行为在网络成瘾与自杀行为之间的关联及可能作用。
在3507名参与者中，5.2%被诊断为网络成瘾，27.4%报告在调查前12个月内有自杀意念，另有9.5%有自杀计划，2.6%有自杀未遂行为。网络成瘾与自杀意念（比值比[OR]=1.79，95%置信区间[CI]：1.32 - 2.44）、自杀计划（OR = 2.32，95%CI：1.57 - 3.42）和自杀未遂（OR = 2.08，95%CI：1.03 - 4.22）相关。调整潜在混杂因素后，网络成瘾与自杀未遂之间的关联无统计学意义。分别将抑郁和冲动相关行为纳入分层回归后，网络成瘾与自杀意念及自杀计划之间的关联大幅降低。而将网络成瘾纳入分层回归时，抑郁、冲动相关行为与自杀意念及自杀计划之间的关联未降低。
青少年网络成瘾似乎与自杀意念和自杀计划相关，且这种关联可能由抑郁和冲动相关行为介导。
