About this trial
The investigators propose a randomized controlled trial to develop and evaluate the impact of promoting advice on diet and lifestyle recommendations for cancer prevention at colorectal cancer screening among individuals who may be at higher risk for colorectal cancer (CRC). The specific objectives of this study are to 1) develop a lifestyle intervention based on evidenced-based diet and lifestyle recommendations (i.e. those proposed by the World Cancer Research Fund (WCRF) and the French National Cancer Institute); 2) evaluate the effect of the intervention on the adherence to the target diet and lifestyle recommendations as well as other subjective health measures, including quality of life; 3) evaluate the effect of the intervention on anthropometrics.
