Abstract

Background: Fibromyalgia syndrome (FMS) is characterized by widespread musculoskeletal pain and tenderness with associated neuropsychological symptoms such as fatigue, unrefreshing sleep, cognitive dysfunction, anxiety, and depression. Osteoporosis is defined as a reduction of bone density. Previous studies to determine an association of FMS with osteoporosis showed mixed results, partially due to small sample sizes and lack of statistical power. Objectives: To evaluate the association of FMS with osteoporosis. Methods: We conducted a case-control study utilizing the database from Israel's largest health maintenance organization. FMS patients were compared to age- and sex-matched controls. Data were analyzed using chi-square and t-tests. Multivariable logistic regression models assessed the association between osteoporosis and FMS. Spearman's rho test was used for correlation. Results: We utilized data from 14,296 FMS patients and 71,324 age- and sex-matched controls. Spearman's rho test showed a significant correlation between FMS and osteoporosis (correlation coefficient 0.55, P < 0.001). A logistic regression for osteoporosis showed an odds ratio [OR] of 1.94 (95% confidence interval [95%CI] 1.83-2.06, P < 0.001) for FMS compared to controls and found higher body mass index to be slight protective (OR 0.926, 95%CI 0.92-0.93, P<0.001). Conclusions: There is a significant correlation between FMS and osteoporosis. Early detection of predisposing factors for osteoporosis in FMS patients and implementation of suitable treatments and prevention measures (such as dietary supplements, resistance or weight bearing exercise, and bone-mineral enhancing pharmacological therapy) may reduce both occurrence rate and severity of osteoporosis and its complications, such as fractures.
