Promoting physical activity in patients with colon adenomas : a randomized pilot intervention trial . BACKGROUND Physical activity decreases risk of colon polyps and colon cancer and might reduce risk of colon cancer recurrence . Focusing on recent calls for translation of epidemiologic evidence into clinical care , our pilot study delivered an evidence-based physical activity intervention in adults with polyps , who are thus at elevated risk of developing colon cancer . The objective was to evaluate change in physical activity , measured by steps per day and minutes of moderate/vigorous physical activity . METHODS Sixteen adults with adenomas detected and removed at screening colonoscopy were recruited to a 12-week physical activity intervention . Participants were randomized to receive a standard ( 30 minutes/day ) or high ( 60 minutes/day ) walking program . Physical activity was measured via blinded pedometer and accelerometer at baseline and follow-up . Intervention messages focused on self-monitoring using pedometers and overcoming barriers to engaging in physical activity . RESULTS Participants in both arms significantly increased objectively measured minutes of moderate/vigorous physical activity over the course of the intervention . Both arms exceeded the intervention goal , but there was not a significant difference between arms at follow-up . Results were similar for pedometer measured physical activity , with a significant overall increase in steps/day from baseline to follow-up , but no between arm difference in change . CONCLUSION Simple interventions of minimal contact time focusing on walking can significantly increase physical activity in individuals at increased risk of developing colon cancer .
