The use of electronic screen devices has a negative effect on sleep. The purpose of this study is to longitudinally examine the effects of various screen use on sleep problems in children under 7 years of age. A total of 314 caregivers of children aged 4−7 years from three cities in Korea were recruited and responded to a self-administered questionnaire from 2017 to 2020. As a result of the analysis of the mixed model designed as a two-leveled structure, the use frequency of smartphones significantly predicted children’s sleep problems (β = 0.328, p < 0.001) compared to that of TV, PC, and tablet PC. In addition, the frequency of smartphone screen use showed a weak but significant correlation with bedtime resistance (r = 0.067, p = 0.009), sleep duration (r = 0.089, p <0.001), nighttime awakening (r = 0.066, p = 0.010), and daytime sleepiness (r = 0.102, p < 0.001). The results of this study suggest that screen time education in Korea should focus on smartphones above all else.
电子屏幕设备的使用对睡眠有负面影响。本研究旨在纵向探讨 7 岁以下儿童各种屏幕使用与睡眠问题的关系。本研究共招募了来自韩国三个城市的 314 名 4-7 岁儿童的照顾者，并在 2017 年至 2020 年期间对他们进行了自我管理式问卷调查。由于采用了两级结构的混合模型分析，与电视、个人电脑和平板电脑相比，智能手机的使用频率显著预测了儿童的睡眠问题（β=0.328，p<0.001）。此外，智能手机屏幕使用频率与上床入睡抵抗（r=0.067，p=0.009）、睡眠时间（r=0.089，p<0.001）、夜间觉醒（r=0.066，p=0.010）和日间嗜睡（r=0.102，p<0.001）呈弱但显著相关。本研究结果表明，韩国的屏幕时间教育应特别关注智能手机。
