每天坐8小時(shí)中風(fēng)風(fēng)險(xiǎn)高7倍

Adults under 60 who spend most of their days sitting have a higher risk of stroke compared to those who spend more time being physically active, a new study finds. People who reported sitting eight or more hours daily and were not very physically active otherwise were seven times more at risk of having a stroke than people who spent fewer than four hours being sedentary and at least 10 minutes exercising each day, according to a study published in Stroke from the American Heart Association.

一項(xiàng)發(fā)表在美國(guó)心臟協(xié)會(huì)出版的期刊《卒中》上的最新研究發(fā)現(xiàn)，對(duì)于年齡在60歲以下的成年人來(lái)說(shuō)，如果每天絕大多數(shù)的時(shí)間都是坐著的，那么與經(jīng)常鍛煉的人相比，中風(fēng)的風(fēng)險(xiǎn)會(huì)高出數(shù)倍。報(bào)告稱(chēng)，那些每天坐8小時(shí)或以上、且極少鍛煉的人，中風(fēng)的可能性要比那些每天坐著的時(shí)間不超過(guò)4小時(shí)、且每天至少鍛煉10分鐘的人高出7倍。

Researchers included the health information of 143,000 adults from the Canadian Community Health Survey in their analysis. The scientists followed the participants, who were 40 years and older with no prior history of stroke, for an average of 9.4 years.

研究人員對(duì)來(lái)自加拿大社區(qū)健康調(diào)查項(xiàng)目的14.3萬(wàn)名成年人的健康信息進(jìn)行了平均長(zhǎng)達(dá)9.4年的跟蹤調(diào)查，參與者年齡均在40歲以上，且無(wú)中風(fēng)病史。

"Sedentary time is thought to impair glucose, lipid metabolism and blood flow, and increase inflammation in the body," said lead study author Dr. Raed Joundi, clinical scholar at McMaster University in Ontario, Canada. "These changes, over time, may have adverse effects on the blood vessels and increase the risk of heart attack and stroke."

研究報(bào)告的主要作者、加拿大安大略省麥克馬斯特大學(xué)臨床學(xué)者瑞德•瓊迪博士說(shuō)："久坐被認(rèn)為會(huì)影響血糖、脂質(zhì)代謝和血液流動(dòng)，增加體內(nèi)炎癥。時(shí)間一長(zhǎng)，這些身體變化可能會(huì)給血管帶來(lái)負(fù)面影響，增加心臟病發(fā)作和中風(fēng)的風(fēng)險(xiǎn)。"
