The presence of small screens in the sleep environment has been associated with shorter sleep duration and later bedtimes in children of normal weight, but the role these devices play in the sleep environment of overweight children is unclear. We sought to examine the association of small screen presence in the sleep environment with sleep behaviors among school-age children with obesity.
We surveyed 526 parents of children ages 6 to 12 years old with a body mass index ≥95th percentile who were participating in a randomized trial to treat childhood obesity. Twelve months after enrollment, parents were asked how frequently their child slept with or near a small screen (defined as a cellphone, smartphone, or texting/chat-capable device). We used multivariable linear regression to examine associations of the presence of small screens with sleep duration, waketime, and bedtime.
Compared with children who rarely/never slept with a small screen in their bedroom, children who did so 1 day or more per week had shorter sleep durations and later bedtimes. After we adjusted for television presence in the bedroom, small screen presence was still associated with shorter sleep duration (-9.9 minutes; P = .02) and later weekday (8.8 minutes; P = .03) and weekend (12.0 minutes; P = .03) bedtimes.
Children with obesity and a small screen present in their sleep environment have shorter sleep durations and later bedtimes than children who rarely/never sleep with a small screen. Pediatricians should consider inquiring about small screens in the bedroom when counseling on healthy sleep and weight management habits.
在正常体重的儿童中，睡眠环境中存在小屏幕与睡眠时间缩短和晚睡有关，但这些设备在超重儿童的睡眠环境中所起的作用尚不清楚。我们试图研究睡眠环境中小屏幕的存在与肥胖儿童的睡眠行为之间的关系。
我们调查了 526 名 6 至 12 岁肥胖儿童的父母，这些儿童的体重指数≥第 95 百分位数，他们正在参加一项治疗儿童肥胖的随机试验。入组 12 个月后，父母被问及他们的孩子多久在小屏幕（定义为手机、智能手机或具有发短信/聊天功能的设备）旁或与小屏幕一起睡觉。我们使用多变量线性回归来检查小屏幕存在与睡眠时间、醒来时间和就寝时间的关联。
与卧室中很少/从不放置小屏幕的儿童相比，每周有 1 天或更多天放置小屏幕的儿童睡眠时间更短，就寝时间更晚。在调整了卧室中电视的存在后，小屏幕的存在仍然与睡眠时间更短（-9.9 分钟；P=0.02）和工作日（8.8 分钟；P=0.03）和周末（12.0 分钟；P=0.03）就寝时间更晚有关。
睡眠环境中存在小屏幕的肥胖儿童睡眠时间更短，就寝时间更晚，而很少/从不放置小屏幕的儿童睡眠时间更长。儿科医生在进行健康睡眠和体重管理习惯的咨询时，应考虑询问卧室中小屏幕的使用情况。
