Abstract

Background: How reduced sleep impacts screen time in children is unclear.

Objectives: To explore how reduced sleep impacts objectively measured screen use.

Methods: One hundred and five children (8-12 years) with caregiver-reported sleep of 8-11 h/night were randomised to 7 nights sleep extension (go to bed 1 h earlier) or sleep restriction (bed 1 h later) in a crossover trial with a 7-night washout between conditions. Sleep and time awake were measured using waist-worn accelerometry (ActiGraph wGT3X-BT) and screen time using wearable cameras (Brinno TLC130 Timelapse) and questionnaires. Camera images were coded as time spent on screens (raw data), including imputation for blocked images (Rules 1 and 2). Within-person differences (95% CI) were calculated in those with matched camera data across sleep intervention weeks, in minutes and as percentage of awake time.

Results: Screen time before school or on weekends did not differ in the 49 children (10.4 years, 51% female, 41% overweight, 78% European) with suitable camera data. After school, children appeared to have similar screen time using raw data (median difference; 25th, 75th percentiles: 18.7 min; -10.2, 72.5), but greater screen time during sleep restriction compared with extension after allowance for blocked images (Rule 2: 66.3 min; 7.5, 102.9 or 6% of awake time; 0.5, 10.0). Parents (n = 98) reported greater total screen use in children during the sleep restriction week (mean difference; 95% CI: 16.8 min; 1.8, 31.8).

Conclusions: In this secondary analysis, getting less sleep appeared to increase screen time in children during the weekday afternoon and evening hours, compared to when they received more sleep.

睡眠不足对儿童屏幕时间的影响：使用屏幕时间客观测量的随机交叉试验的二次分析。

背景：睡眠减少如何影响儿童的屏幕时间尚不清楚。目的：探讨睡眠减少对客观测量屏幕使用的影响。方法：在一项交叉试验中，105名8-12岁的儿童（照护者报告睡眠时间为8-11小时/晚）被随机分为7晚睡眠延长组（提前1小时睡觉）或睡眠限制组（晚1小时睡觉），两种情况之间有7晚洗脱。采用腰戴式加速度计（ActiGraph wGT3X-BT）测量睡眠和清醒时间，采用可穿戴式相机（Brinno TLC130 Timelapse）和问卷调查测量屏幕时间。相机图像被编码为在屏幕上花费的时间（原始数据），包括对阻塞图像的imputation（规则1和2）。在睡眠干预周内，以分钟为单位，以清醒时间的百分比计算具有匹配相机数据的人体内差异（95% CI）。结果：49名儿童（10.4岁，51%为女性，41%为超重，78%为欧洲人）在上学前或周末看屏幕的时间没有差异。放学后，使用原始数据，儿童的屏幕时间似乎相似（中位数差异；第25，第75百分位数：18.7分钟；-10.2,72.5），但在睡眠限制期间，与考虑阻塞图像后的延长相比，屏幕时间更长（规则2:66.3分钟；7.5,102.9或6%的清醒时间；0.5,10.0）。父母（n = 98）报告说，在睡眠限制周期间，儿童使用屏幕的总次数更多（平均差异；95% CI: 16.8 min; 1.8, 31.8）。结论：在这项二次分析中，与睡眠充足的孩子相比，睡眠不足似乎会增加他们在工作日下午和晚上看屏幕的时间。试验注册：ACTRN12618001671257澳大利亚新西兰临床试验注册中心；ANZCTR。

期刊介绍： Pediatric Obesity is a peer-reviewed, monthly journal devoted to research into obesity during childhood and adolescence. The topic is currently at the centre of intense interest in the scientific community, and is of increasing concern to health policy-makers and the public at large. Pediatric Obesity has established itself as the leading journal for high quality papers in this field, including, but not limited to, the following: Genetic, molecular, biochemical and physiological aspects of obesity – basic, applied and clinical studies relating to mechanisms of the development of obesity throughout the life course and the consequent effects of obesity on health outcomes Metabolic consequences of child and adolescent obesity Epidemiological and population-based studies of child and adolescent overweight and obesity Measurement and diagnostic issues in assessing child and adolescent adiposity, physical activity and nutrition Clinical management of children and adolescents with obesity including studies of treatment and prevention Co-morbidities linked to child and adolescent obesity – mechanisms, assessment, and treatment Life-cycle factors eg familial, intrauterine and developmental aspects of child and adolescent obesity Nutrition security and the "double burden" of obesity and malnutrition Health promotion strategies around the issues of obesity, nutrition and physical activity in children and adolescents Community and public health measures to prevent overweight and obesity in children and adolescents.
