Dependency on the Internet in daily life is increasing, and the negative consequences this dependence may have on mental health are not sufficiently understood. The aim of this study was to investigate the relationship between Korean adolescents' Internet usage time and their mental health. This cross-sectional study included 29,811 high school students ages 16-18 from the 2018 Korea Youth Risk Behavior Web-Based Survey. Participants' mean Internet usage time was 193.4±1.6 min/day. Internet usage time was associated with sex, grade level, type of school, living arrangement, economic status, academic achievement, and experience of school violence. With regard to mental health, subjective health status, stress, feelings of sadness, and suicidal ideation were also related to Internet usage time. The group with more than average Internet usage had poorer subjective health, higher level of stress, and had feelings of sadness and suicidal ideation compared to the group with less than average Internet usage. To effectively manage Internet usage time, interventions to lower Internet usage and leisure programs that could replace Internet usage need to be developed.
日常生活对互联网的依赖程度正在不断提高，而这种依赖可能对心理健康造成的负面影响尚未得到充分认识。本研究旨在调查韩国青少年上网时间与心理健康之间的关系。本横断面研究纳入了 2018 年韩国青少年风险行为网络调查中年龄在 16-18 岁的 29811 名高中生。参与者平均每天上网 193.4±1.6 分钟。上网时间与性别、年级、学校类型、居住安排、经济状况、学业成绩和校园暴力经历有关。就心理健康而言，主观健康状况、压力、悲伤感和自杀意念也与上网时间有关。与上网时间少于平均水平的组相比，上网时间超过平均水平的组主观健康状况较差，压力水平较高，并且感到悲伤和有自杀意念。为了有效管理上网时间，需要制定降低上网时间的干预措施和可以替代上网的休闲计划。
