THE RELATIONSHIP BETWEEN FUNCTIONAL STATUS, FATIGUE, AND INSOMNIA IN PATIENTS WITH FIBROMYALGIA

Aim: The aim of our study is to investigate the relationship between functional status, fatigue and insomnia in patients with fibromyalgia syndrome (FMS). Methods: Demographic data, marital status, educational status, smoking, presence of additional disease and exercise habits of the patients participating in the study were questioned. Fibromyalgia functional status was assessed with the Fibromyalgia Impact Questionnaire, fatigue assessment with the 'Functional Assessment of Chronic Disease Treatment-Fatigue', and insomnia with the “Insomnia Severity Index”. Result: The study was completed with a total of 64 patients (age=45.06±12.98 years, body mass index=26.84±4.67kg/m2). 76.6% (n=49) of the patients were women. The mean functional status score of the patients was 58.36±6.81, the mean fatigue score was 26.07±5.70, and the mean insomnia score was 12.64±3.59. Insomnia scores of female patients were significantly higher than males (p=0.016). The insomnia score of those with a body mass index (BMI) above normal (≥25) was also significantly higher than those within the normal range (p=0.007). No correlation was found between the functional status of FMS patients and fatigue and insomnia (p>0.05). Conclusion: The majority of FMS patient sare at the lower threshold of insomnia and their functions are mildly adversely affected. The effect of insomnia in women is higher than in men, especially increased BMI has been determined as one of the predisposing factors of insomnia.
