核心提示:假定一个人休闲时花在屏幕前的时间代表他总共坐着的时间,那么我们的研究结果支持这样的结论:坐着的时间长,会提高得心血管疾病和过早死亡的风险。。该研究报告提出一种理论,就是坐着的时候,人体内的“脂蛋白脂酶”活性会下降,最严重的可能下降90%之多,以致血液中的脂肪(如三酸甘油酯)增多,同时可能影响到葡萄糖代谢,因而可能与二型糖尿病的发病有关。


it turns out your overprotective mother may have been right: too much television may, in fact, kill you. a new international study is suggesting that anyone who spends more than four hours a day in front of any "screen-based entertainment" - be it television, videogames or the internet - is increasing their chance of heart attack or stroke by 113%, regardless of any exercise routine to the contrary.

the problem, however, isn't the screen-based entertainment itself, but that it means the participant is spending that time sitting down, according to the report's lead author, emmanuel stamatakis from the department of epidemiology and public health at university college in london:

“assuming that leisure-time screen time is a representative indicator of overall sitting, our results lend support to the idea that prolonged sitting is linked to an increased risk for cardiovascular disease and premature mortality... i would speculate that the list of sitting-specific health harms will be getting longer and longer in the years to come; this area of research is in its infancy.”

the report puts forward the theory that sitting reduces the activity of an enzyme called lipoprotein lipase by up to 90%, which can lead to an increase in fats like triglycerides in the blood, as well as potentially impair glucose metabolism, suggesting a possible link to type two diabetes. ideally, according to stamatakis, we should try and move towards a way of life where standing and moving is more common in our daily routine than sitting. somewhere, kinect and wii makers are planning brand new "play our games or die" ad campaigns as you read these very words.

原来你那位喋喋不休过分关顾你的妈妈可能真的说对了:看太多电视可能会要你的命!一项新的国际研究显示,每天沉迷于“屏幕上的娱乐”——如电视、电子游戏、上网——超过4小时的人,爆发心脏病或中风的几率会增加113%,即使经常锻炼身体也于事无补。

据研究报告的第一作者、伦敦大学学院流行病学和公共卫生系的 emmanuel stamatakis 指出,问题不在哪一种屏幕上的娱乐,而是在于长时间坐着不动。他说:

“假定一个人休闲时花在屏幕前的时间代表他总共坐着的时间,那么我们的研究结果支持这样的结论:坐着的时间长,会提高得心血管疾病和过早死亡的风险。...... 我相信,将来我们会陆续发现越来越多因为坐的时间太长而对身体健康造成的伤害。这方面的研究才刚刚起步。”

该研究报告提出一种理论,就是坐着的时候,人体内的“脂蛋白脂酶”活性会下降,最严重的可能下降90%之多,以致血液中的脂肪(如三酸甘油酯)增多,同时可能影响到葡萄糖代谢,因而可能与二型糖尿病的发病有关。stamatakis 认为,最理想的应对是试图改变我们的生活方式,在日常生活中多些时间站着和走动,减少坐着不动的时间。当你还在读这篇文章的时候,也许 kinect 和 wii 的制造商已经在策划推出以“不玩我们的游戏你会早死”为主题的新广告攻势呢!
