Evidence on the association between different screen behaviours and cardiometabolic biomarkers in children is limited. We examined the independent relationship of TV time and PC time with cardiometabolic biomarkers in Dutch 5-6 year old children.
Cross-sectional analyses were conducted December 2012-March 2013 using data from a multi-ethnic cohort (the ABCD study, n = 1,961). TV and PC time and physical activity were assessed by parent-report. Body weight, height, waist circumference and blood pressure were measured using a standard protocol. Fasting capillary blood samples were collected. A cardiometabolic function score was computed as the mean of the inverted standardised values of waist circumference, mean of systolic and diastolic blood pressure, glucose, HDLC (not inverted), and triglycerides.
Mean TV time was 1.2 (± 0.8) hr/day and mean PC time was 0.2 (± 0.4) hr/day. After adjustment for birth weight, height, maternal education, PC time, and physical activity, excessive TV time (>2 hrs/day) was adversely associated with waist circumference (b = 0.39, 95% CI: 0.004;0.78) while PC time was beneficially associated with HDLC levels (b = 0.04, 95% CI: 0.001;0.08). We found no additional significant associations of TV time, or PC time with any of the cardiometabolic biomarkers.
We found no convincing evidence for an association between TV or PC time and cardiometabolic function in apparently healthy 5-6 yr olds.
关于儿童不同屏幕行为与心脏代谢生物标志物之间关联的证据有限。我们研究了荷兰5至6岁儿童看电视时间和玩电脑时间与心脏代谢生物标志物之间的独立关系。
2012年12月至2013年3月进行了横断面分析,使用了来自多民族队列(ABCD研究,n = 1,961)的数据。通过家长报告评估看电视和玩电脑的时间以及身体活动情况。使用标准方案测量体重、身高、腰围和血压。采集空腹毛细血管血样。计算心脏代谢功能评分,为腰围标准化值倒数的均值、收缩压与舒张压均值、血糖、高密度脂蛋白胆固醇(未取倒数)和甘油三酯的均值。
平均每天看电视时间为1.2(± 0.8)小时,平均每天玩电脑时间为0.2(± 0.4)小时。在对出生体重、身高、母亲教育程度、玩电脑时间和身体活动进行调整后,看电视时间过长(> 2小时/天)与腰围呈负相关(b = 0.39,95%可信区间:0.004;0.78),而玩电脑时间与高密度脂蛋白胆固醇水平呈正相关(b = 0.04,95%可信区间:0.001;0.08)。我们未发现看电视时间或玩电脑时间与任何心脏代谢生物标志物之间存在其他显著关联。
在看似健康的5至6岁儿童中,我们未找到令人信服的证据证明看电视或玩电脑时间与心脏代谢功能之间存在关联。
