Sitting Increases the Risk of Dying Early
久坐易早逝,赶紧站起来

Sitting too much may increase the risk of dying prematurely, while replacing sitting time with just standing or moderate physical activity could counteract the effect.

久坐的生活习惯会提高早逝的风险,而要降低这种风险,仅仅需要多花一些时间站立或者进行一些温和的活动。

Researchers used survey data from 54 countries, analyzing time spent sitting more than three hours a day along with data on population size, actuarial tables and overall deaths. The study is in the American Journal of Preventive Medicine.

研究人员收集了来自54个国家的调查数据,分析每天静坐超过3小时与人口数量、保险报表以及死亡率之间的关系。这篇研究文章发表在《美国预防医学杂志》(American Journal of Preventive Medicine)上。

More than 60 percent of people worldwide spend more than three hours a day sitting down, and the researchers calculated that sitting time contributed to some 433,000 deaths from 2002 through 2011.

全世界超过60%的人口每天静坐的时间超过了3小时,研究者的计算表明,从2002年到2011年,这种静坐的生活习惯至少与433,000例死亡有关。

They estimated mean sitting time across countries at 4.7 hours a day. Reducing that time by 50 percent, they calculated, would result in a 2.3 percent decline in all-cause mortality.

估算表明这些国家中的人口每天平均静坐时间为4.7个小时。如果将该时间减少一半,人口死亡率将降低大约2.3个百分点。

The association between time spent sitting and mortality has been found in other studies, and the link persists even after accounting for other physical exercise.

久坐的习惯与死亡率的关系在别的研究中已有报道,即便排除运动带来的健康增益效应,前者的联系依旧存在。

“This is the best data we have for now,” said the lead author, Leandro Rezende, a doctoral candidate at the University of São Paulo School of Medicine, “but we don’t know if it’s a causal relationship.

“这些数据就是我们目前所知的全部,”来自圣保罗大学医学院的博士研究生,莱安德罗·雷森德(Leandro Rezende)如是说,“我们还不清楚这是不是因果关系。”

“There are things we can do,” he continued. “Stand up, and go have a drink of water instead of keeping the water bottle at your desk. Or just stand up every so often. Standing alone increases your energy expenditure.”

“我们不是无能为力,”他接着解释说。“站起来,去喝一杯水,而不要把水壶放在你的桌子上。或者就是单纯地站一会儿。仅仅是站立本身就可以增加你的体力消耗。”
