BACKGROUND Suicide is a leading cause of death in adolescents. Problematic internet use (PIU) has been associated with suicidal behavior in this age group. To assess this association, we reviewed population-based studies that examined the relationship between PIU and suicidal behavior. METHODS We searched PubMed, PsycINFO, and Web of Science for studies published in English from 1995 through 2021. Only studies with the stated aim to examine the relationship between PIU and suicidal behavior in participants age 13 through 18 were included. Also, each study had to include a measure of internet overuse with resultant impairment/distress. To minimize selection bias, studies with convenience samples were excluded. RESULTS Seven cross-sectional studies with at least 9,500 participants each met the inclusion/exclusion criteria. Five assessed both suicidal ideation and suicide attempts and 2 examined suicidal ideation only. All studies found a statistically significant association between suicidal behavior and PIU. Effect sizes were mostly in the minimal to small range. CONCLUSIONS All 7 studies supported a positive relationship between PIU and suicidal ideation and suicide attempts, which could be clinically important. Longitudinal studies with improved methodology are needed to identify risk factors and determine whether PIU is causally related to suicidality.

青少年有问题的互联网使用和自杀行为：综述。

背景技术自杀是青少年死亡的主要原因。有问题的互联网使用（PIU）与这个年龄段的自杀行为有关。为了评估这种关联，我们回顾了基于人群的研究，这些研究检验了 PIU 与自杀行为之间的关系。方法 我们检索了 PubMed、PsycINFO 和 Web of Science，查找 1995 年至 2021 年以英文发表的研究。仅纳入了旨在检查 13 至 18 岁参与者自杀行为与 PIU 之间关系的研究。此外，每项研究都必须包括对互联网过度使用造成的损害/困扰的衡量。为了尽量减少选择偏差，排除了使用方便样本的研究。结果 七项横断面研究至少有 9,500 名参与者，每项研究均符合纳入/排除标准。其中 5 名同时评估了自杀意念和自杀企图，2 名仅评估了自杀意念。所有研究均发现自杀行为与 PIU 之间存在统计学显着关联。效应大小大多在最小到较小的范围内。结论 所有 7 项研究都支持 PIU 与自杀意念和自杀企图之间存在正相关关系，这可能具有重要的临床意义。需要采用改进的方法进行纵向研究来识别风险因素并确定 PIU 是否与自杀有因果关系。
