Exercise Decreases Risk of Future Active Disease in Patients with Inflammatory Bowel Disease in Remission.
It is well known that being physically active impacts on quality of life for patients with IBD, however very little is known about its role in disease activity. This study examines whether exercise affects the chance of flares of disease in IBD patients who are in remission.
A total of 6626 adults completed an internet based survey organised through the Crohn’s and Colitis Foundation of America. The online survey asked about the patients’ disease; medication use; overall quality of life; overall health status and physical activity. Patients in remission were identified based on a scoring system (disease activity index) widely used by gastroenterologists and level of exercise was measured using another scoring system (Godin leisure-time activity index). Only 1857 patients met the criteria for being included in the study.
The researchers found that for patients in remission a higher exercise level was associated with a reduced chance of having a flare of active disease for both Crohn’s and Ulcerative Colitis. This study highlights the role of exercise as a potential factor influencing disease behaviour.
One of the problems with this study is that patients who do more exercise were more likely to complete the online survey so the results may not be the same in a different group of patients. It is interesting to note that not even 30% of the 6626 adults were included in the analysis.
