This study aimed to clarify the effects of television/digital versatile disc (TV/DVD) viewing time and portable electronic device (PED) usage time on sleep duration and bedtime and the difference between the effects of TV/DVD and PED on sleep. The effect of TV/DVD viewing time or PED usage time on sleep duration and bedtime was analyzed using a multiple logistic regression analysis adjusted for covariates. A total of 74,525 participants were included in the analysis, using data from Japan Environment and Children's Study. TV/DVD viewing was not associated with short sleep duration, but PED usage was associated with short sleep duration. In addition, the risk of short sleep duration increased as PED usage time increased. We also investigated the effects of sleep habits at age 1 year on sleep at age 3 years. This study showed that late bedtime at age 1 year posed a significant risk of late bedtime at age 3 years. In summary, particular caution should be paid to PED use from a child's health perspective, and sleep habits should be focused on bedtime from the age of 1 year.
本研究旨在阐明电视/数字多功能光盘(TV/DVD)观看时间和便携式电子设备(PED)使用时间对睡眠时间和就寝时间的影响,以及 TV/DVD 和 PED 对睡眠影响的差异。使用协变量调整的多因素逻辑回归分析,对 TV/DVD 观看时间或 PED 使用时间对睡眠时间和就寝时间的影响进行了分析。使用来自日本环境与儿童研究的数据,对 74525 名参与者进行了分析。看电视/ DVD 与睡眠时间短无关,但使用 PED 与睡眠时间短有关。此外,随着 PED 使用时间的增加,短睡眠时间的风险也会增加。我们还研究了 1 岁时的睡眠习惯对 3 岁时睡眠的影响。本研究表明,1 岁时的晚睡时间会显著增加 3 岁时的晚睡时间。总之,从儿童健康的角度来看,应特别注意 PED 的使用,并且应从 1 岁开始关注睡眠习惯的就寝时间。
