Discapacidad funcional en pacientes con fibromialgia en un hospital en Lima, Perú

Background: Fibromyalgia is a rheumatological disorder characterized by generalized pain of imprecise localization that mainly affects women. It is associated with fatigue, anxiety, depression, and functional capacity is greatly affected by the coexistence of these disorders. Methods: It is a series of cross-sectional cases, using secondary data from 126 patients with fibromyalgia who attended the outpatient clinic of a hospital at Lima at the rheumatology service during February 2020.We try to determine the frequency of functional disability and explore associated factors in patients diagnosed with fibromyalgia with or without depression. Functional capacity and the presence of depressive symptoms were measure by validated scales. A multivariate multiple logistic regression analysis was performed to assess whether depression is an independent risk factor for disability. Results: The age had a median of 53.5 (IQR: 46-60) years, 122 participants were women. In addition, 42 (33.33%) patients had depression and 76 (60.32%) patients had functional disability. In the multivariate analysis, it was found that depression is an independent risk factor for functional disability after adjusting for diabetes, presence of 3 or more comorbidities, intensity of fatigue and associated symptoms [OR 3.09 (1.24 - 7.70); p: 0.015]. Conclusions: Depression is an independent factor for functional incapacity in patients with fibromyalgia.
