Comparison of the Frequency of Fibromyalgia Syndrome Between Those with and Without Obstructive Sleep Apnea Syndrome

Abstract

ABS TRACT Objective: Sleep disturbance plays an important role in the etiopathogenesis of fibromyalgia syndrome (FMS). This study aimed to compare the frequency of FMS between those with and without obstructive sleep apnea syndrome (OSAS). In addition, it was aimed to examine the relationship between polysomnography parameters and FMS. Materials and Methods: Twenty participants with OSAS (OSAS group) and 20 participants without OSAS (control group) were included in the study. All participants were evaluated for FMS diagnosis using the American College of Rheumatology FMS criteria. The chronic widespread pain levels of all participants were evaluated by the Numerical Rating Scale (NRS), their depression levels were evaluated by the Beck Depression Inventory (BDI), and their anxiety levels were evaluated by the Beck Anxiety Inventory (BAI). Results: The number of patients diagnosed with FMS, chronic widespread pain NRS levels, BAI scores, and chronic pain durations of the patients in the OSAS group were found to be significantly higher than in the control group. BDI scores of both groups were similar. Among the patients in the OSAS group, no significant difference was detected in terms of polysomnography parameters between patients with FMS and patients without FMS. Conclusion: In this study, the frequency of FMS in patients with OSAS was higher than in those without OSAS. This association should be kept in mind when evaluating patients with FMS and OSAS. In addition, in this study, it was determined that the presence of FMS did not affect the polysomnography parameters of patients with OSAS.
