An analysis of data from more than 3.5 million people showed that fibromyalgia is more common in patients with certain diseases such as type 2 diabetes and Behcet syndrome than in the general population overall. The study, “,” was recently published in the journal Rheumatology International . The study's goal was to determine the occurrence of fibromyalgia in the general population worldwide. The researchers pooled statistical information from 65 studies, which included 3,609,810 people. Most of the studies included in the analysis used the American College of Rheumatology (ACR) criteria in assigning a diagnosis of fibromyalgia (namely generalized pain for at least three months with 11 out of 18 tender points during physical examination). In the general population, the study found that 1.78% of people have fibromyalgia, especially women — researchers found that 3.98% of women suffer from the disease while 0.01% of the men analyzed do. There were no significant differences in the rates of fibromyalgia in different regions of the globe. Fibromyalgia was, however, found to be more common in people with some medical conditions in specific studies. Fibromyalgia was seen in 15.2% of patients in internal medicine and rheumatology clinics, leading the authors to propose that patients referred to those clinics need more investigation and consideration regarding a possible fibromyalgia diagnosis. Higher rates of fibromyalgia were also seen in patients with type 2 diabetes (14.8%
