Assessing diet, exercise, sleep and other lifestyle habits in people with a known increased risk for bowel cancer and who have regular colonoscopies

This study will explore how diet and lifestyle, as well as age and gender (and other non-modifiable risk factors), are involved in the development of bowel cancer and pre-cancerous lesions (adenomas) in people considered at above average risk for bowel cancer due to either family history of bowel cancer or prior history of colorectal adenoma. Who is it for? Individuals are eligible to join this study if they are aged 18 years or older, and are currently enrolled in the Southern Cooperative Program for the prevention of colorectal cancer (SCOOP) Program for a surveillance colonoscopy. Study details: All individuals enrolled in the SCOOP program will be invited to complete and return an online or paper survey at years 1, 2 and 3, which will ask questions on diet, exercise, sleep and other lifestyle factors. The results from each survey and the changes in lifestyle over the 3 years will be compared to the findings at the regular surveillance colonoscopies, in particular the presence of advanced colorectal neoplasia (adenoma or cancer). It is hoped that the results of the study will improve the understanding of the interactions between diet and lifestyle behaviour, with the non-modifiable risk factors on the development of advanced neoplasia. It is hoped that this will be useful for identifying high-risk individuals who may benefit from targeted interventions to reduce their risk of developing bowel cancer and reducing the need for unnecessary colonoscopies for lower risk patients.
