最新一期《美國流行病學(xué)期刊》(American Journal of Epidemiology)報道,，經(jīng)常久坐的生活型態(tài)，可能會提高罹患大腸癌的風(fēng)險,。
之前曾有醫(yī)學(xué)研究報告指出,，如果工作方式屬于經(jīng)常久坐，得大腸直腸癌的風(fēng)險可能因此提高,。但是,，這些過去調(diào)查的研究對象，多半都是在某段特定時間當(dāng)中針對某種職業(yè)的工作者進(jìn)行調(diào)查,。
最新一期的《美國流行病學(xué)期刊》則刊登澳洲科學(xué)家的最新醫(yī)學(xué)研究指出,，如果在日常生活中常常久坐，也可能會提高罹患大腸癌的風(fēng)險。
在這項研究當(dāng)中,，科學(xué)家以918名大腸癌患者在2005年至2007年之間的就業(yè)數(shù)據(jù),、生活型態(tài)以及體能活動進(jìn)行分析，并以1021名民眾做為對照組,。
統(tǒng)計結(jié)果顯示,，如果超過10年以上都是從事久坐類型的工作，得大腸癌的風(fēng)險比從來不曾從事靜態(tài)工作者高2倍,，得到結(jié)腸癌的風(fēng)險也比不曾從事靜態(tài)工作者增加44%,。（生物谷Bioon.com）

Long-Term Sedentary Work and the Risk of Subsite-specific Colorectal Cancer
Terry Boyle*, Lin Fritschi, Jane Heyworth and Fiona Bull
Research suggests that sedentary behavior may increase the risk of some chronic diseases. The aims of the study were to examine whether sedentary work is associated with colorectal cancer and to determine whether the association differs by subsite. A total of 918 cases and 1,021 controls participated in a population-based case-control study of colorectal cancer in Western Australia in 2005–2007. Data were collected on lifestyle, physical activity, and lifetime job history. The estimated effects of sedentary work on the risk of cancers of the proximal colon, distal colon, and rectum were analyzed by using multinomial logistic regression. Compared with participants who did not spend any time in sedentary work, participants who spent 10 or more years in sedentary work had almost twice the risk of distal colon cancer (adjusted odds ratio = 1.94, 95% confidence interval: 1.28, 2.93) and a 44% increased risk of rectal cancer (adjusted odds ratio = 1.44, 95% confidence interval: 0.96, 2.18). This association was independent of recreational physical activity and was seen even among the most recreationally active participants. Sedentary work was not associated with the risk of proximal colon cancer. These results suggest that long-term sedentary work may increase the risk of distal colon cancer and rectal cancer.
