研究人员在审视五个基础研究的过程中剔除了已经患病因而更有可能久坐的病人的数据。
One of the analysis's limitations was that it relied on self-reporting, as people tend to underestimate how much sitting they do, Dr. Katzmarzyk said.
卡兹马兹克说,该项分析的局限之一就是完全依赖自我报告,而人们往往倾向于低估自己坐着的时间。
The study bolsters an emerging body of research that points to a number of dangers associated with leading a sedentary lifestyle.
这项研究为一系列声称久坐的生活方式会导致一系列风险的研究提供了支持。
Last year, scientists found that people who worked 10 years in sedentary jobs, or jobs that don't require a lot of energy expenditure, had twice the risk of colon cancer and a 44% increased risk of rectal cancer, compared with people who had never worked sedentary jobs.
去年,科学家发现,与那些从未从事过需要久坐工作的人相比,那些坐着工作10年的人,或是工作中不需要消耗太多能量的人,罹患结肠癌的风险高出一倍,罹患直肠癌的风险高出44%。
And in March, scientists found that the rate of cancers linked to obesity and lack of physical activity, such as cancers of the kidney, pancreas, lower esophagus and uterus, rose every year from 1999 through 2008.
今年3月份,科学家发现罹患癌症的几率与肥胖程度和缺乏体育运动有关,比如从1999年到2008年间,肾癌、胰腺癌、食道癌和子宫癌的发病率每年都在增加。
