Smartphone usage is indispensably beneficial to people's everyday lives. However, excessive smartphone usage has been associated with physical and mental health problems. This study aimed to evaluate the association of smartphone usage with depressive symptoms, suicidal thoughts, and suicide attempts in Korean adolescents.
This cross-sectional study was conducted in 54,603 Korean adolescent participants (26,930 male and 27,673 female) in the Korea Youth Risk Behavior Survey in 2017 who reported their smartphone use. We performed multiple logistic regression analysis to evaluate the association of smartphone use with mental health after adjusting for relevant covariates.
Among the participants, 25.6% of male students and 38.4% of female students reported using their smartphone for at least 30 hours per week. As time duration of smartphone usage increased, the risk of experiencing depressive symptoms, suicidal thoughts, and suicide attempt tended to increase, with odds ratios (95% confidence interval) of 1.18 (1.10-1.26), 1.18 (1.08-1.29), and 1.34 (1.11-1.60), respectively, for high smartphone usage compared with low smartphone usage. These associations remained significant with only slight change in odds ratios after consideration of problems that may be caused by smartphone usage, such as conflicts with family members or peers, or disturbance in school work.
Smartphone overuse was independently associated with an increased risk of mental health problems, which did not seem to be mediated by the problems caused by smartphone usage.
智能手机的使用对人们的日常生活有着不可或缺的益处。然而，过度使用智能手机与身心健康问题相关联。本研究旨在评估韩国青少年智能手机使用与抑郁症状、自杀念头及自杀未遂之间的关联。
这项横断面研究在2017年韩国青少年风险行为调查的54,603名韩国青少年参与者（26,930名男性和27,673名女性）中进行，这些参与者报告了他们的智能手机使用情况。我们进行了多因素逻辑回归分析，以在调整相关协变量后评估智能手机使用与心理健康之间的关联。
在参与者中，25.6%的男学生和38.4%的女学生报告每周使用智能手机至少30小时。随着智能手机使用时长的增加，出现抑郁症状、自杀念头和自杀未遂的风险倾向于增加，与低智能手机使用量相比，高智能手机使用量的比值比（95%置信区间）分别为1.18（1.10 - 1.26）、1.18（1.08 - 1.29）和1.34（1.11 - 1.60）。在考虑到智能手机使用可能引发的问题，如与家人或同伴的冲突或学业干扰后，这些关联仍然显著，比值比仅有轻微变化。
智能手机过度使用与心理健康问题风险增加独立相关，这似乎并非由智能手机使用引发的问题所介导。
