Improve Colorectal Cancer Prevention by Motivational and Community-based Approaches

It has been estimated that 19,000 Colorectal Cancers (CRC) could be prevented each year in France by changing individual risk behaviours (sedentary lifestyle, overweight, diet, alcohol). The cancer screening appears to be an opportune moment for health promotion and to inform about CRC risk factors. The PRECÔTION study proposes an innovative scheme based on informative, motivational and community-based approaches. The objectives are to take advantage of patients' visits for colonoscopy to raise awareness and initiate individual prevention actions according to their own risk in order to modify individual risk behaviour. Patients who come for a colonoscopy at the Centre Léon Bérard and who are negative (80% of cases) will benefit from an evaluation to identify their individual risk factors, determine their level of risk level for CRC and their motivation to change their behaviour. Participants with a low level of risk will receive remote support in physical activity and nutrition via digital media based on a motivational approach. Participants will be proposed a monthly collective physical activity session, which will allow them to interact with each other and develop a community approach. Participants with an intermediate level of risk will be offered a collective health education session, in addition to the the support offered to participants with a low level of risk. Participants with a high level of risk will receive, in addition to the the support offered to participants with an intermediate level of risk, an individual motivational coaching and a connected watch. A logbook will also be given to all participants to accompany them on the different tools, especially for monitoring their goals. The PRECÔTION study aims to evaluate these tools as innovative means of prevention before evaluate their effectiveness on a larger scale.
