Abstract
Background Pain is common, both as acute and as chronic (long-lasting more than 3 months). Acute pain is normally treated effectively, chronic pain though has a poor prognosis. Chronic pain has a high prevalence, both as localized pain, especially low back pain (CLBP) and as generalized pain (CWP). It has a more complex background including both sensitization, injuries and other disorders. A large number of the patients with localised low back pain have been seen to develop widespread pain. Could the reason behind that be a higher prevalence of widespread pain initially? Aim Is the prevalence of chronic low back pain highest as local pain or in combination with either chronic regional or widespread pain? Methods A questionnaire was sent out 2016 as the 5th follow-up to a study (EpiPain) started in 1995. 1184 responded to the study which contained questions regarding quality of life (SF-36 Health Survey), chronic pain and healthcare consumption. The data was statistically analysed to find the associations between CLBP, the number of locations with pain and quality of life. Results In a general population, the prevalence of CLBP is 50% higher combined with CWP than without. The impact on Quality of life (SF-36) is higher from CLBP than from other sites of pain, but the impact from the number of sites with pain are totally higher. Discussion The higher impact on the SF-36 Index for CLBP compared with other localised pain is in line with other studies. Also the larger impact of many pain locations and widespread pain are supported by other studies.
