研究：“屏幕时间”过多会影响儿童健康
<p>英国卫生部下属机构——英国公共卫生日前发布研究报告称，看电视、碟片，以及玩电脑游戏时间过长会影响儿童的身心健康。有证据表明，长时间“盯屏幕”的孩子出现情绪沮丧、焦虑和抑郁等状况的几率更高。此前已有医生指出，儿童缺乏锻炼会导致更多不健康的生活方式，目前英国11岁的儿童中有三分之一为超重或肥胖。研究发现，每天玩电脑游戏时间在一小时以内的孩子幸福感是每天玩游戏四小时以上孩子的三倍。卫生部意在通过这一系列研究证据让人们知道，参加体育活动会让孩子学习时注意力更集中，与同学关系更融洽，同时减少忧虑、抑郁等状况的出现。</p><p>该报告还引述联合国儿童基金会近期发布的一份报告称，全球29个富裕国家中，英国儿童的健康状况排名第16位。报告指出，英国11岁、13岁和15岁的青少年每个工作日看电视时间超过2小时的比例分别为62%、71%和68%；而瑞士三个年龄段青少年的这一比例均低于35%。</p><p><span word="Spending">Spending</span> <span word="too">too</span> <span word="much">much</span> <span word="time">time</span> <span word="in">in</span> <span word="front">front</span> <span word="of">of</span> <span word="television">television</span>, <span word="DVDs">DVDs</span> <span word="and">and</span> <span word="computer">computer</span> <span word="games">games</span> <span word="is">is</span> <span word="taking">taking</span> <span word="its">its</span> <span word="toll">toll</span> <span word="on">on</span> <span word="children">children</span>'<span word="s">s</span> <span word="physical">physical</span> <span word="and">and</span> <span word="mental">mental</span> <span word="health">health</span>, <span word="according">according</span> <span word="to">to</span> <span word="a">a</span> <span word="government">government</span>-<span word="commissioned">commissioned</span> <span word="report">report</span> <span word="published">published</span> <span word="on">on</span> <span word="Wednesday">Wednesday</span>.</p><p><span word="Public">Public</span> <span word="Health">Health</span> <span word="England">England</span> <span word="says">says</span> <span word="there">there</span> <span word="is">is</span> <span word="evidence">evidence</span> <span word="that">that</span> <span word="children">children</span> <span word="who">who</span> <span word="spend">spend</span> <span word="more">more</span> <span word="time">time</span> <span word="watching">watching</span> <span word="screens">screens</span> <span word="tend">tend</span> <span word="to">to</span> <span word="have">have</span> <span word="higher">higher</span> <span word="levels">levels</span> <span word="of">of</span> <span word="emotional">emotional</span> <span word="distress">distress</span>, <span word="anxiety">anxiety</span> <span word="and">and</span> <span word="depression">depression</span>.</p>
