Adenomatous polyp recurrence and physical activity in the Polyp Prevention Trial (United States).

Objective: To examine prospectively the association between physical activity and adenomatous polyp recurrence.

Methods: Information on past year total physical activity was collected annually through an interview-administered questionnaire from the 1905 men and women enrolled in a randomized dietary intervention study, the Polyp Prevention Trial. Multiple logistic regression analysis was used to examine the association between physical activity and polyp recurrence in up to three years of follow-up from baseline colonoscopy.
