The
present literature review update presented a significant increase in
fibromyalgia prevalence studies in the world. Quality studies on prevalence had
increased due to the COPCORD methodology.
Fibromyalgia (FM)
is a chronic pain syndrome that is characterised by generalised musculoskeletal
pain, often associated with sleep disorders, fatigue, somatic and cognitive
symptoms.
Marques AP et
al. conducted a literature review on the prevalence of fibromyalgia. For this
study, a bibliographical survey from 2005 to 2014 in the MEDLINE, Web of
Science, Embase, LILACS and SciELO databases was done, and 3274 records were
identified. According to the inclusion criteria, five researchers picked up
studies that obtained the prevalence of fibromyalgia. While fibromyalgia
studies in associated diseases were excluded from the review. Also, based on
the title and abstract screening, around 2073 irrelevant articles were
excluded.
About 210
articles with full texts were assessed for eligibility and finally included 39
studies, described in 41 articles. The studies were divided into 4 categories:
1. Prevalence of
fibromyalgia in the general population
2. Prevalence of
fibromyalgia in women;
3. Prevalence of
fibromyalgia in rural and urban areas;
4. Prevalence of
fibromyalgia in special populations.
The literature
revealed that the prevalence of fibromyalgia in the general population between
found to be 0.2 and 6.6%. The 2.4 and 6.8% women population had fibromyalgia.
In urban areas it was found to be more prevalent, i.e. between 0.7 and 11.4%.
It was less prevalent in rural areas ranging between 0.1 and 5.2%, and in
special populations it was 0.6 and 15%.
Overall, it was
estimated that there is a significant increase in fibromyalgia prevalence throughout the world. The new, 2010 American College of
Rheumatology (ACR) criteria have not been widely used yet. The COPCORD
(Community-oriented program for control of Rheumatic Diseases) methodology has
increased the quality of studies on the prevalence of rheumatic diseases in
general.
