The Prevalence of Fibromyalgia in the General Population A Comparison of the American College of Rheumatology 1990, 2010, and Modified 2010 Classification Criteria

摘要

Objective. The American College of Rheumatology (ACR) 1990 fibromyalgia classification criteria are based on the presence of widespread pain and tenderness. In 2010, new criteria were proposed that focused more on multiple symptoms, and these criteria were later modified to require only self report of symptoms. The current study aimed to determine the population prevalence of fibromyalgia and to compare differences in prevalence using the alternative criteria.
