To Much Sitting May Raise Risk of Colorectal Cancer Risk For Men

Men who sit to much may have a higher risk of experiencing colorectal cancer according to a new study. Researchers at the Columbia University Mailman School of Public Health reported their findings at a meeting of the American Association for Cancer Reaserch. The researchers found an association between time spent being sedentary and risk of recurrence of colorectal adenomas, which are also known as colorectal adenomatous polyps. Colorectal adenomas usually give way to colorectal cancer; the adenomas, once detected, are typically removed during a colonoscopy.

“Given the substantial increase in risk of colorectal adenoma recurrence we observed for men with the highest sedentary time, we believe it would be beneficial to see ‘reduce prolonged sitting time’ added to the list of public health recommendations currently in place for health promotion and disease prevention,” study researcher Christine L. Sardo Molmenti, Ph.D., M.P.H., a postdoctoral research fellow in the Department of Epidemiology at the university, said in a statement.

The study is based on data from 1,730 people who were a part of trials conducted at the University Of Arizona. All of the study participants had had at least one colorectal adenoma removed in the six months before starting in the study.

The study discovered that men who spend 11.38 or more hours a day participating in sedentary activities (like reading or watching TV) had a 45 percent higher risk of recurrence of colorectal adenoma, versus men who spend 6.9 or fewer hours a day engaged in sedentary activities.

The researchers also found that high participation in sedentary activities and low participation in physical activities was linked with a 41 percent higher risk of recurrence of colorectal adenomas. This is compared with men who had low participation in both sedentary activities and physical activities,

According to a report presented at a 2011 meeting of the American Institute for Cancer Research, more than 170,000 cancer cases might be the result of extended time spent sitting each year, MyHealthNewsDaily reported. And that’s not good, considering other research presented at the meeting showed that in the U.S., adults spent 15.5 hours, on average, sitting each day.

And this is just one more recent study linking prolonged sitting with a major health risk. To read more and learn how to protect yourself from the dangers of sitting read Is Your Chair Killing You? Available on
