The epidemiology of chronic generalized musculoskeletal pain.
Chronic widespread musculoskeletal pain has been subjected to several epidemiological studies during the last decade. According to these, approximately 10% of the general population report such complaints, clearly indicating chronic widespread musculoskeletal pain as a major health problem in the Western world. Almost unanimously, all studies found higher rates of such complaints among women compared with men, but the mechanisms responsible for the skewed gender ratio remain unknown.Chronic widespread musculoskeletal pain is the clinical hallmark of fibromyalgia and has been the subject of numerous epidemiological studies. The prevalence of fibromyalgia is reportedly 3-5%, again with a significant female predominance. Although the aetiopathogenesis of both fibromyalgia and chronic widespread musculoskeletal pain without other features of fibromyalgia remains an enigma, there is a body of evidence suggesting psychological and sociocultural factors as important for contracting such pain syndromes.
