ABSTRACT Chronic pain (CP) is a major health problem with important consequences on people suffering from it, and with a social and economic big impact. However, few studies have been carried out in general Spanish population analyzing this concern. OBJECTIVES The aim of this study was to know the prevalence of CP in the general Spanish population, establish groups of pain patients based on the characteristics of the painful experience and identify factors associated with these groups. RESULTS CONCLUSION This study shows a high prevalence of CP and identifies 2 different groups of patients in pain in the Spanish population. Likewise, it is relevant the increased perception of pain experience observed in women and in subject worried about his/her family.

METHODS Printed by • Design: Cross-sectional study. • Sample: Multistage cluster sampling for a representative sample of the Spanish population over 18 years. • Procedure: Computer Assisted Telephonic Interviews (CATI), between February and June 2011. • Variables: Presence of CP present in 4 or 5 days a week, for at least three months. Characteristics and effect of pain. • Analyses: Descriptive analysis. Cluster analysis to classify individuals in pain according to duration of pain, number and location of pain sites, and intensity of pain. Binary logistic regression model to determine the factors associated with pain in each group previously identified. 16,6 8,2 24,8 9,7 20,3 27,1 0 5 10 15 20 25 30 35 Global Male Female 18-44 45-64 >=65 Percentage Sex Age Prevalence of chronic pain.
