背景的主要目的是确定屏幕时间（电视+电脑）和代谢综合征（MetS）在adolescents.Methods的研究样本包括1803名青少年（12-19岁）从1999-04年美国国家健康和营养检查调查之间的剂量反应关系。平均每日屏幕时间（结合电视，电脑和视频游戏的使用）是自我报告的。代谢综合征的定义是根据青少年标准与国家胆固醇教育计划的成人标准相联系（高甘油三酯、高空腹血糖、高腰围、高血压和低HDL胆固醇中>= 3）。在≥ 5小时/天（3.07，1.48-6.34）筛选时间类别中，MetS的优势比（95%置信区间）以剂量-反应方式（P趋势< 0.01）增加。体力活动有一个最小的影响屏幕时间和MetS.Conclusions之间的关系屏幕时间与MetS的可能性增加，在一个独立的体力活动的剂量依赖性的方式。这些研究结果表明，基于生活方式的青年公共卫生干预措施应包括一个旨在减少屏幕时间的具体组成部分。
Background The primary objective was to determine the dose-response relation between screen time (television + computer) and the metabolic syndrome (MetS) in adolescents.Methods The study sample included 1803 adolescents (12-19 years) from the 1999-04 US National Health and Nutrition Examination Surveys. Average daily screen time (combined television, computer and video game use) was self-reported. MetS was defined according to adolescent criteria linked to the adult criteria of the National Cholesterol Education Program (>= 3 of high triglycerides, high fasting glucose, high waist circumference, high blood pressure and low HDL cholesterol).Results After adjustment for relevant covariates, the odds ratios (95% confidence intervals) for MetS increased in a dose-response manner (P-trend < 0.01) across = 5 h/day (3.07, 1.48-6.34) screen time categories. Physical activity had a minimal impact on the relation between screen time and MetS.Conclusions Screen time was associated with an increased likelihood of MetS in a dose-dependent manner independent of physical activity. These findings suggest that lifestyle-based public health interventions for youth should include a specific component aimed at reducing screen time.
