Sleep disorder is a common problem in children that can jeopardize their health and well-being. With the popularity of electronic devices such as portable tablets and smartphones in the 21st century, children are spending much more time on screen, but the impact of such change on children's sleep disorder has been less investigated so far. This study aims to examine the dose-response association between time spent on different electronic devices and children's sleep disorder.
The design of this study is a cross-sectional study.
We randomly selected 2278 children aged 3-6 years from 15 kindergartens in Tongling, China. The potentially non-linear association between screen-viewing time (i.e. television [TV], computer, iPad, Phone) and the risk of sleep disorder was examined using a logistic generalized additive model.
We observed a J-shaped association between TV viewing time and the risk of sleep disorder, with a threshold of 1 h/day. For each 1 h/day increment in TV viewing time over the threshold, the risk of sleep disorder increased by 12.35% (95% confidence interval: 1.87-23.92%). This association seemed to be greater for girls than boys and for TV viewing at weekend than on weekdays, but the difference was not statistically significant (P-value>0.05). We did not find adequate evidence of an adverse effect of more time spent on computer, iPad and Phone.
This study suggests a positive but non-linear relationship between time spent on watching TV and sleep disorder in Chinese preschool children. Setting the TV viewing time limit less than 1 h/day may help reduce the risk of developing sleep disorder. Further investigation is also needed to examine and compare the effects of heavy use of other electronic devices on sleep disorder.
睡眠障碍是儿童常见的问题，可能会危及他们的健康和幸福。在 21 世纪，随着便携式平板电脑和智能手机等电子设备的普及，儿童花在屏幕上的时间更多，但到目前为止，这种变化对儿童睡眠障碍的影响还没有得到太多的研究。本研究旨在研究不同电子设备的使用时间与儿童睡眠障碍之间的剂量反应关系。
本研究设计为横断面研究。
我们从中国铜陵的 15 所幼儿园中随机抽取了 2278 名 3-6 岁的儿童。使用逻辑广义加性模型检查了屏幕观看时间（即电视[TV]、计算机、iPad、手机）与睡眠障碍风险之间的非线性关系。
我们发现，看电视时间与睡眠障碍风险之间存在 J 形关系，阈值为 1 小时/天。与阈值内每天增加 1 小时的电视观看时间相比，睡眠障碍的风险增加了 12.35%（95%置信区间：1.87-23.92%）。这种关联似乎在女孩中比男孩中更大，在周末看电视比在工作日更大，但差异无统计学意义（P 值>0.05）。我们没有发现足够的证据表明花更多的时间在计算机、iPad 和手机上会产生不良影响。
本研究表明，中国学龄前儿童看电视时间与睡眠障碍之间存在正相关但非线性关系。将每天看电视的时间限制在 1 小时以内可能有助于降低患睡眠障碍的风险。还需要进一步调查，以检查和比较其他电子设备使用过度对睡眠障碍的影响。
