Answer

Cases of fibromyalgia have been reported by researchers from around the world. Fibromyalgia exhibits no race predilection. Researchers have reported the condition in all ethnic groups and cultures.

In the United States, chronic pain and fatigue are extremely prevalent in the general population, [63, 76, 77] especially among women and persons of lower socioeconomic status. The prevalence of regional pain is 20%; widespread pain, 11%; and chronic fatigue, approximately 20%.

Fibromyalgia, as defined by the 1990 American College of Rheumatology (ACR) classification criteria, [9] has a prevalence of 3-5% in females and 0.5-1.6% in males. Because the ACR criteria are insensitive, the actual prevalence of fibromyalgia is higher, particularly in men.

Fibromyalgia is the second most common disorder that rheumatologists encounter, seen in 15% of evaluated patients. Approximately 8% of patients cared for in primary care clinics have fibromyalgia.

The annual economic burden of fibromyalgia in 2005 was $10,199 per patient per year, nearly double that of matched controls. [78] It has been estimated that overall, fibromyalgia costs the US economy over $9 billion annually. [79]
