To find the prevalence of "Generalised Pain of the Locomotive System" (GPLS) in the Principality of Asturias.
A crossover study, consisting of an interview and a medical examination.
Urban and rural population throughout the Autonomous Community of the Principality of Asturias.
The population group under study was chosen at random by multi-stage and proportional sampling. Criteria validated for the diagnosis of GPLS were applied.
The response was 75.6% (702 people), in whom 9.2% prevalence of GPLS was found, with a significant preponderance of women. A statistical association of GPLS both with limitations in daily activities and with the presence of anxiety or depression was found.
GPLS shares many features with Fibromyalgia syndrome. Its high prevalence and its association with functional and psychological disturbances indicate the important social repercussions of this disorder.
