Screen media usage has become increasingly commonplace in daily life with children initiating themselves to screen media at an early age. Given the high prevalence of screen viewing among children worldwide, its impact on children's health has become a cause for concern. Unfortunately, little information on the independent association between sleep habits and screen time in French children is currently available. The main aim of this study was to assess possible relationships between screen time and sleep habits (quality, duration, etc.) among young middle school students in France.
A total of 448 (55 % girls) 11-to-12-year-olds from 5 schools were included. Body weight and height were measured according to standard procedures and BMI percentiles were determined based on international reference values. Sleep parameters were obtained by sleep diaries and visual estimations. A sleep diary was maintained for one week to record sleeping and waking times and related information. Information on lifestyle habits (sedentary behaviours, physical activity, and dietary intake) was obtained via standardised questionnaires.
Participants were 11.5 (±0.4) years of age. From total sample, 25.5 % reported screen time ≥2hours/d during school days and 62.7 % during school-free days. High screen time was associated with significantly poorer sleep habits and these results remained valid after adjustment for several confounding factors (body mass index, sex, center and parental level of educational attainment) (P<0.05).
This study highlights an association between longer screen time and shorter sleep duration in French middle school students aged 11 to 12 years. Preventive measures on use of and exposure to screens are called for. Further studies are necessary to confirm our findings.
屏幕媒体的使用在日常生活中越来越普遍，儿童在很小的时候就开始接触屏幕媒体。鉴于全球儿童中屏幕观看的高普及率，其对儿童健康的影响已成为一个令人担忧的问题。不幸的是，目前关于法国儿童睡眠习惯与屏幕时间之间独立关联的信息很少。本研究的主要目的是评估法国初中学生屏幕时间与睡眠习惯（质量、时长等）之间的可能关系。
纳入了来自5所学校的448名11至12岁的学生（55%为女孩）。按照标准程序测量体重和身高，并根据国际参考值确定BMI百分位数。通过睡眠日记和视觉评估获得睡眠参数。维持一周的睡眠日记以记录入睡和醒来时间及相关信息。通过标准化问卷获取生活方式习惯（久坐行为、体育活动和饮食摄入）的信息。
参与者的年龄为11.5（±0.4）岁。在总样本中，25.5%的人报告在上学日屏幕时间≥2小时/天，在非上学日为62.7%。高屏幕时间与明显较差的睡眠习惯相关，在对几个混杂因素（体重指数、性别、中心和父母教育程度）进行调整后，这些结果仍然有效（P<0.05）。
本研究强调了法国11至12岁中学生屏幕时间较长与睡眠时间较短之间的关联。需要采取关于屏幕使用和接触的预防措施。有必要进行进一步研究以证实我们的发现。
