为了评估英国儿童使用屏幕媒体(电视和电脑时间，卧室里有一台电视)与身体肥胖之间的纵向联系。参与者是来自英国千年队列研究的12名 556名儿童，他们从7岁到11岁进行了跟踪调查。评估了屏幕媒体使用与以下结果之间的关联：身体质量指数(BMI)、脂肪质量指数(FMI)和超重。在完全调整的模型中，在7岁时拥有卧室电视与显著更高的BMI和FMI(男孩的超重BMI=0.29，95%可信区间(CI)0.06-0.52；女孩的超重BMI=0.57，95%CI 0.31-0.84；男孩的超重FMI=0.20，95%CI 0.04-0.37；女孩的超重FMI=0.39，95%CI 0.21-0.57)和超重风险的增加(相对风险=1.21，95%CI 1.07-1.36；与没有卧室电视相比，11岁女孩的相对危险度为1.31，95%可信区间为1.15~1.48。看电视或数字多功能光盘的时间只与女孩超重的风险增加有关。无论男女，7岁时使用电脑与后来的身体肥胖都没有关系。在这项具有全国代表性的英国儿童样本中，在孩子的卧室里放一台电视是超重和体脂增加的独立风险因素。儿童肥胖预防策略应将儿童卧室中的电视视为肥胖的风险因素。
To assess longitudinal associations between screen-based media use (television (TV) and computer hours, having a TV in the bedroom) and body fatness among UK children. Participants were 12 556 children from the UK Millennium Cohort Study who were followed from age 7 to age 11 years. Associations were assessed between screen-based media use and the following outcomes: body mass index (BMI), fat mass index (FMI), and overweight. In fully adjusted models, having a bedroom TV at age 7 years was associated with significantly higher BMI and FMI (excess BMI for boys=0.29, 95% confidence interval (CI) 0.06–0.52; excess BMI for girls=0.57, 95% CI 0.31–0.84; excess FMI for boys=0.20, 95% CI 0.04–0.37; excess FMI for girls=0.39, 95% CI 0.21–0.57) and increased risk of being overweight (relative risk (RR) for boys=1.21, 95% CI 1.07–1.36; RR for girls=1.31, 95% CI 1.15–1.48) at age 11 years, compared with having no bedroom TV. Hours spent watching TV or digital versatile disks were associated with increased risk of overweight among girls only. Computer use at age 7 years was not related to later body fatness for either gender. Having a TV in the child’s bedroom was an independent risk factor for overweight and increased body fatness in this nationally representative sample of UK children. Childhood obesity prevention strategies should consider TVs in children’s bedrooms as a risk factor for obesity.
