A study to see if people change behaviours that can affect their health after having a colonoscopy (CATALYST)

This study collected information about changes in smoking, diet, drinking alcohol and physical activity in people who had a colonoscopy. They also collected information from their partners.

People who have a colonoscopy and are then diagnosed with bowel cancer, or other conditions such as diverticulitis or polyps, may choose to make changes to their lifestyle. They may stop smoking, change their diet, reduce the amount of alcohol they drink or increase the amount of physical activity they do. These are called health related behaviours.

The researchers doing this study looked at health related behaviours of people who had a colonoscopy that showed abnormal cells. They compared them with people who had a colonoscopy that showed normal bowel cells. They also looked at the health related behaviours of the partners of people in both groups.

The aim of the study was to understand more about health related behaviours in these groups of people and their partners.
