Background:Behçet’s Disease (BD) is a chronic, inflammatory, rheumatic disease that is characterized by mucocutaneous lesions and can be seen major organ involvement such as eyes, musculoskeletal system, gastrointestinal system and central nervous system. Impaired quality of life, aerobic capacity, respiratory function and life satisfaction, sleep disorders, depression, anxiety and fatigue are seen commonly in BD patients like the other rheumatic diseases. Considering that regular physical activity effects survival for patients and healthy people, it is important to determine the factors affecting physical activity level and exercise barriers.Objectives:The aim of this study is to investigate physical activity level and exercise barriers in patients with BD.Methods:45 patients were included in the study. Physical activity level, exercise barriers, fatigue, depression, pain, quality of life and aerobic capacity were evaluated with International Physical Activity Questionnaire (IPAQ), Exercise Barriers and Benefits Scale (EBBS), Fatigue Severity Scale (FSS), Beck Depression Inventory (BDI), Visual Analog Scale (VAS), Behçet’s Disease Quality of Life Questionnaire (BDQoL) and 6 minutes walk test, respectively. Spaerman’s Correlation Coefficient were used to investigate the relationships between exercise barriers and other parameters.Results:IPAQ demonstrated that 22 (48.8%) of the patients had low level physical activitiy. Additionally, physical activity levels significantly correlated with both exercise barriers (rho= -0.345) and exercise benefits (rho= 0.320) (p<0.05). BDQoL scores also correlated significantly with exercise barrier scores (rho= 0.338), (p<0.05). No significant relationships were observed for other parameters.Conclusion:Exercise and physical activity are of great importance because of its positive contribution to the musculoskeletal system for BD patients’ rehabilitation. Thinking of negative effects of physical inactivity, patients with Behçet disease should be encouraged to exercise. Also, reasons of physical inactivity should be investigated and treated.References:[1]Ilhan B, Can M, Alibaz-Oner F, Yilmaz-Oner S, Polat-Korkmaz O, Ozen G et al.
