The purpose of the study was to investigate the level ofexerciseparticipationin patients withinflammatoryboweldisease(IBD) and to investigate their intention,attitudeand preferencetowardexercise. The data of 158 IBD patients that participated in a self-administered survey at Severance Hospital between March 2013 and November 2013 were included in this cross sectional and descriptive analysis. Questionnaires included 3 sections to determine the IBD patient's currentexerciseparticipation,attitudetowardexercise, andexercisepreferences. This study investigated IBD patients both collectively, and according to their specificdisease: Crohn'sdisease(CD) (n=62), Ulcerative colitis (UC) (n=73) and intestinal Behçet'sdisease(BD) (n=23). IBD patients currently participate in 103 min/week ofexerciseincluding mild, moderate and strenuous intensity, with BD patients being the least active, followed by CD, and UC being most active. The majority of IBD patients foundexerciseto be pleasant (57.7%), beneficial (80.5%), sensible (71.8%), uplifting (61%) and good (70.5%), and 44.4% foundexerciseto be enjoyable. This study shows the IBD patients'participation,attitudeandpreferencestowardexerciseand provides much needed information for the development of evidence basedexerciseprograms that are specific to IBD.
