Abstract
Most information about fibromyalgia derives from the clinic, and it is not known how persons with fibromyalgia in the community might differ from clinic patients, and whether their illness syndromes might be more or less severe. Additionally, the outcome of fibromyalgia in the community as well as the clinic is not known. Findings: The prevalence of fibromyalgia in the general population appears to around 2%, with more than 90% of those being female. Fibromyalgia occurs more frequently in the elderly than previously supposed. Fibromyalgia in the clinic is associated with self-reported disability, but little is known about fibromyalgia disability in the community. Conclusions: Fibromyalgia can be identified in the community at rates in excess of the rheumatoid arthritis, and constitutes a significant public health concern. Additional studies of fibromyalgia disability and outcome are required.
