Abstract

Purpose: The purpose of this study was to investigate the mediating effect of fatigue on the relationship between pain and sleep disturbance in patients with ankylosing spondylitis. Methods: The subjects of this study were 109 patients with ankylosing spondylitis who visited the rheumatology department in a university hospital. Subjects completed structured questionnaires measuring pain, sleep disturbance, and fatigue. Data were analyzed using t-test, Pearson's correlation coefficients, and 3-step regression analysis. Results: Pain was positively correlated with fatigue (r=.60, p<.001) and sleep disturbance (r=.45, p<.001). Fatigue was positively correlated with sleep disturbance (r=.55, p<.001) and had a mediating effect on the relationship between pain and sleep disturbance. Conclusion: The findings confirm that pain in patients with ankylosing spondylitis affects fatigue and its accumulation has a mediating effect on increasing the level of sleep disturbance. In clinical practice, education on symptom management for patients with ankylosing spondylitis needs to be provided for encouraging proper exercise and rest. Patient education should also include strategies to reduce fatigue and promote sleep in daily lives in addition to pain management.
