研究：男性長期看電視更易患腸癌
Too much TV may raise men's colorectal cancer risk
Men who watch more than four hours of TV a day significantly increase their risk of developing bowel cancer, researchers have found.
研究人員發現,男性每天看電視超過4小時,患腸癌的風險明顯增加.
Experts tracked 500,000 British people for six years - and found a significant link between sedentary behavior and bowel cancer risk.
專家們對50萬名英國人進行了6年的追蹤研究,發現了久坐行為與腸癌風險之間存在的重要聯系.
But the strongest risk was found among men, particularly those who watched lots of television.
而患病風險最大的是男性,尤其是那些經常看電視的男性.
The scientists, from the University of Oxford, Imperial College London and the UN International Agency for Research on Cancer, found men who sat in front of the television for more than four hours a day were 35 percent more likely to develop bowel cancer.
牛津大學、帝國理工學院和聯合國國際癌癥研究中心的科學家們發現,男性每天坐著看4小時電視,其患腸癌的可能性要增加35%.
For women the increased risk of television watching was just 11 percent - but when they examined the figures they found this was not statistically significant.
長期看電視的女性患腸癌的風險只增加11%,但科學家們對該數據進行檢測后發現并沒有統計學意義.
Intriguingly, they found no link between computer screen time and bowel cancer risk.
有趣的是,他們發現在電腦屏幕前久坐與患腸癌的風險沒有關聯.
The researchers suspect men are more likely to smoke, drink and eat junk food than women while watching TV.
研究人員認為,男性在看電視時比女性更容易抽煙、喝酒、吃垃圾食品.
The findings, published in the British Journal of Cancer, revealed 2,391 people of the 500,000 went on to develop bowel cancer.
這項發表在《英國癌癥期刊》的研究顯示,50萬人中有2391人患上了腸癌.
Dr Neil Murphy, lead researcher based at IARC in France, said: 'Previous research suggests that watching TV may be associated with other behaviors, such as smoking, drinking and snacking more, and we know that these things can increase the risk of bowel cancer.
法國國際癌癥研究中心首席研究員尼爾•墨菲博士稱："此前的研究表明,看電視可能與抽煙、喝酒、吃零食等其他行為聯系在一起,而我們知道這些行為會增加患腸癌的風險."
'Being sedentary is also associated with weight gain and greater body fat. Excess body fat may influence the blood levels of hormones and other chemicals which affect the way our cells grow, and can increase bowel cancer risk..'
"久坐還會導致體重體脂增加.體脂過量會影響血液中的激素以及其他影響細胞生長的物質,增加患腸癌的風險."
Professor Linda Bauld, Cancer Research UK's prevention expert, said: 'This study poses interesting questions such as why screen time from computers didn't increase the risk of bowel cancer but watching TV did.
