Objectives: To determine the prevalence of fibromyalgia in Chiclayo district. Methods: A descriptive, exploratory, cross-sectional study was conducted among habitants from 18 to 65years. A random, conglomerate and stratified sample was obtained. The district was divided in 34 zones based on a 2011 census. A Spanish version of a questionnaire that looked for symptoms of fibromyalgia was applied. Individuals with diffuse body aches identified through the questionnaire were evaluated by the principal investigator following the criteria of the American College of Rheumatology of 1990. Results: 548 habitants were interviewed; 504 fulfilled the inclusion criteria; 333 (66.3%) were females. The most common underlying medical conditions were depression (14, 2.5%); hypothyroidism(11, 2%) and anxiety (8, 1.4%). Mean age was 39.7 ± 13.6 years; the prevalence of diffuse body aches was 8.1% (95% CI: 4.9-9.4) and of fibromy algia was 2.99% (95% CI: 1.5-4.4); the prevalence in males was 4.1% and 2.4% in females; there were no sociodemographic differences between patients with diffuse body aches and fibromyalgia. Among those with fibromy algia, there was higher number of painful zones (p=0.0001) and higher frequency of insomnia (p=0.0024). Conclusions: Diffuse body aches and fibromyalgia had similar prevalence rates than previously reported in other studies. There are clinical differences between patients with diffuse body aches and fibromyalgia.
