AbstractPain has become the most common accompanying symptom in patients seeking medical advice, and it is one of the main issues in public health. In Spain, there are no reliable data about the impact of pain in general population. The aim of the study was to estimate the prevalence of acute and chronic pain in the Spanish general population. An epidemiological observational population-based cross-sectional study was carried out by means of a telephone survey. Multistep stratified quota-adjusted sampling was performed with people aged 18-95 years. A computer-assisted questionnaire was administered, covering physical pain symptoms, site, frequency, perceived cause, therapeutic measures and interference with daily life activities. There were 11,980 useful contacts, with 5000 effective interviews (42% of useful sample). Of the interviewees, 29.6% (95% confidence interval, 28.3-30.8%) reported having had pain the day before (women, 37.6%; men, 20.9%) and 43.2% the week before. Most common pain sites were lower extremities (22.7%) and back (cervical and lumbar levels) (21.5%), followed by head (20.5%). Frequency of pain increased with age, reaching 42.6% for people older than 65 years. Among people complaining of pain during the last day or week, duration of symptoms was higher than 3 months in 54% (chronic pain), representing 23.4% of the Spanish general population; most common causes of chronic pain were arthritis, rheumatism and migraine. Regarding treatment, 61.7% of people complaining of pain said they were taking drugs. Source of drug treatment advice was a physician or a nurse in 66.4% of cases and self-prescription in 29%. It is concluded that pain, particularly chronic pain, has a high prevalence in the Spanish general population and a significant impact on occupational and social relationships.Copyright 2002 European Federation of Chapters of the International Association for the Study of Pain.
