Does Sedentary Behavior Influence the Recurrence of Precancerous Colorectal Tumors?

logo1267406_mdA new study presented at the 12th Annual AACR International Conference concluded that men who spend the most time engaged in sedentary behaviors are at the greatest risk of recurrent colorectal adenoma (benign tumors or polyps known to be  precursors of colorectal cancer)  Researchers believe this is the first study to look at the relationship between sedentary behavior and recurrence of colorectal adenoma. .

There were 1,730 participants who had had one or more colorectal adenoma removed during colonoscopy in the six months before the study enrollment and who also completed a self-administered questionnaire including questions about leisure, recreation,. household, and othe categories of activity at enrollment in the study.

When researchers evaluated all data they found no association between sedentary behaviors and colorectal adenoma recurrence. However, when they looked at the data by gender they found that men who reported spending more than 11.38 hours a day engaged in sedentary behaviors such as writing, typing, or working on a computer and reading, were 45 % more likely to experience colorectal adenoma recurrence compared to men who spent fewer than 6.9 sedentary hours a day. No association between sedentary behavior and colorectal adenoma recurrence for women was found. In addition, men reporting high levels of sedentary behavior and low levels of participating in recreational activities such as walking, jogging, and playing golf . were 41 percent more likely to experience colorectal adenoma recurrence than men who reported low levels of both sedentary behaviors and recreational recreational activities. More research is planned by the group.
