Study of the Impact of a Physical Activity Programme on the Quality of Life of Patients With Inflammatory Bowel Disease

Crohn's disease and haemorrhagic rectocolitis are Chronic Inflammatory Bowel Diseases (CIBD) which evolve by flare-ups interspersed with periods of remission . The incidence of these two diseases is increasing in France in adults but also and especially in children and adolescents. Indeed, according to data from the EPIMAD registry, from 1988-1990 to 2009-2011, a significant increase in the incidence of both Crohn's disease and haemorrhagic rectocolitis was observed in adolescents (10-16 years): for Crohn's disease from 4.2 to 9.5/10 5 (+126%; P <0.001) and for UC from 1.6 to 4.1/10 5 (+156%; P <0.001). Over the long term, Crohn's disease can progress to intestinal destruction that can be complicated by stricture(s), obstruction(s), fistula(s) and/or abscesses leading to surgical treatment estimated at 50% after 10 years of Crohn's disease progression 1.

Anti-TNFα therapies are widely prescribed for Crohn's disease because they control symptoms, heal the mucosa, reduce hospital admissions and improve quality of life. However, they are associated with side effects often reported by patients, such as asthenia, weight gain and joint pain, symptoms that could be improved by regular physical activity.

Regular physical activity at a mild to moderate intensity can control inflammation in general and intestinal inflammation in particular during IBD. The effectiveness of a physical activity programme has been evaluated during IBD, but the data are limited to a few studies. Overall, PA improves quality of life but also improves control of disease symptoms and fatigue . The aim of the present work is to evaluate the impact of a physical activity programme on quality of life in patients with IBD. This programme will also evaluate the impact of physical activity on 1) anxiety-depression, 2) fatigue (a frequent and difficult to manage symptom in IBD), 3) IBD activity, 4) smoking cessation.
