2015年2月27日讯 /生物谷BIOON/-- 近日欧洲几所研究机构Universities of Zaragoza and Sao Paulo 的研究人员在International Journal of Cardiology上发表了一项关于儿童看电视的研究。得出结论表示，每天在屏幕前呆了两个小时足以增加了30%的高血压风险。研究还指出，如果没有任何日常体力活动或每天活动少于一个小时，风险按50％增加。多年来一直有研究寻找久坐看电视的生活方式和年轻人肥胖之间的关系，而这项研究揭露了这一习惯与患高血压风险有更大的关系。

科研人员在来自欧洲八个国家（西班牙，德国，匈牙利，意大利，塞浦路斯，爱沙尼亚，瑞典和比利时）16228位2-9岁的儿童中选定了的5221儿童，检测记录相关参数。两年随访后，再次检测了其中5062位儿童的相关数据，预测并评价了预高血压，高血压的发生率和久坐行为与它们之间的效应关系。通过计算，研究人员发现预高血压和高血压的整体发生率分别为121/1000和110/1000。而每天久坐两小时的儿童高血压发生率明显增加，运动少于1小时每天的儿童患高血压风险比久坐看电视的儿童更大。

作为非传染性疾病之一，高血压在成人发病率相当高。已经有不同研究表明，在婴儿期和青春期的动脉血压水平，对成人高血压风险有巨大的影响。要克服这个情况，专家建议，年轻人应该开展每天至少60分钟的体力活动，并提醒，久坐不动的活动持续时间不能超过每天两小时。（生物谷Bioon.com）

Abstract
& k% V7 j9 {1 V( N2 z- NBackground/objectives
  f5 g& ]/ H. k% IHigh blood pressure (HBP) is one of the most important risk factors for cardiovascular diseases and it has a high prevalence in pediatric populations. However, the determinants of the incidence of Pre-HBP and HBP in children are not well known. i) To describe the incidence of HBP in European children; and ii) to evaluate the effect of physical activity (PA) and sedentary behavior (SB) on the Pre-HBP and HBP.

Methods
6 Q6 J; G  P, O; f3 nThe IDEFICS cohort study. A total of 16,228 children 2–9?years at baseline were recruited by complex sampling population-based survey in eight European countries. At baseline (T0), 5221 children were selected for accelerometer measurements; 5061 children were re-examined 2?years later (T1). We estimated the incidence of Pre-HBP and HBP and evaluate the effect of PA and SB on the Pre-HBP and HBP, by computing relative risks and the corresponding 95% confidence intervals (RR, 95% CI).

Results
Incidences of Pre-HBP and HBP per year were: 121/1000 children and 110/1000 children, respectively. We found that children maintaining SB?>?2?h/d during the two year follow-up showed a RR of having HBP of 1.28 (1.03–1.60). Children in T1 not performing the recommended amount of PA (<60?min/d) have a RR of HBP of 1.53 (1.12 to 2.09). We found no association between pre-HBP and the behaviors.

Conclusion
' a" |' i, L9 d1 EThe incidence of pre-HBP and HBP is high in European children. Maintaining sedentary behaviors during childhood increases the risk of developing HBP after two years of follow-up.
