Over the past decades, children have been increasingly using screen devices, while at the same time their sleep duration has decreased. Both behaviors have been associated with excess weight, and it is possible they act as mutually reinforcing behaviors for weight gain. The aim of the study was to explore independent, prospective associations of screen time and sleep duration with incident overweight in a sample of European children.
Data from 4,285 children of the IDEFICS/I.Family cohort who were followed up from 2009/2010 to 2013/2014 were analyzed. Hours per day of screen time and of sleep duration were reported by parents at baseline. Logistic regression analyses were carried out in separate and mutually adjusted models controlled for sex, age, European country region, parental level of education, and baseline BMI z-scores.
Among normal weight children at baseline (N = 3,734), separate models suggest that every hour increase in screen time and every hour decrease in sleep duration were associated with higher odds of the child becoming overweight or obese at follow-up (OR = 1.16, 95% CI: 1.02-1.32 and OR = 1.23, 95% CI: 1.05-1.43, respectively). In the mutually adjusted model, both associations were attenuated slightly ( screen time OR = 1.13, 95% CI: 0.99-1.28; sleep duration OR = 1.20, 95% CI: 1.03-1.40), being consistently somewhat stronger for sleep duration.
DISCUSSION/CONCLUSION: Both screen time and sleep duration increased the incidence of overweight or obesity by 13-20%. Interventions that include an emphasis on adequate sleep and minimal screen time are needed to establish their causal role in the prevention of overweight and obesity among European children.
在过去的几十年中，儿童使用屏幕设备的时间越来越长，而与此同时他们的睡眠时间却减少了。这两种行为都与超重有关，而且它们可能是导致体重增加的相互增强行为。本研究的目的是在欧洲儿童样本中探索屏幕时间和睡眠时间与超重发生率的独立、前瞻性关联。
分析了 IDEFICS/I.Family 队列的 4285 名儿童的数据，这些儿童从 2009/2010 年至 2013/2014 年进行了随访。父母在基线时报告每天的屏幕时间和睡眠时间。在单独和相互调整的模型中进行逻辑回归分析，控制了性别、年龄、欧洲国家/地区、父母的教育水平和基线 BMI z 分数。
在基线时体重正常的儿童中（N=3734），单独的模型表明，屏幕时间每增加 1 小时和睡眠时间每减少 1 小时，与儿童在随访时超重或肥胖的几率增加相关（OR=1.16，95%CI：1.02-1.32 和 OR=1.23，95%CI：1.05-1.43）。在相互调整的模型中，这两种关联都略有减弱（屏幕时间 OR=1.13，95%CI：0.99-1.28；睡眠持续时间 OR=1.20，95%CI：1.03-1.40），而睡眠时间的关联略强。
讨论/结论：屏幕时间和睡眠时间都使超重或肥胖的发生率增加了 13%-20%。需要进行干预，强调充足的睡眠和最小的屏幕时间，以确定它们在预防欧洲儿童超重和肥胖方面的因果作用。
