Responses to questions about headache and use of acute pain medications were linked to demographic registries. MOH was defined as headache \u226515 days\/month plus self-report of use of pain medications \u226510 or 15 days\/month, in the last three months. Weighted prevalence proportions were calculated.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Among 55,185 respondents, chronic headache prevalence was 3.0% (95% CI: 2.3\u20133.2) and MOH prevalence was 2.0% (95% CI: 1.8\u20132.1). Both conditions were more common among females and the middle-aged. Respondents on social welfare or receiving early retirement pensions had the highest prevalences. Among those with chronic headache, 44.7% overused over-the-counter analgesics for headache; paracetamol 41.5%; a combination of different pain relievers 25.3%; ibuprofen 21.9%; opioids 17.0%; combination preparations 14.3%; and triptans 9.1%.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>The highest prevalence of chronic headache and MOH was seen among people with low socioeconomic position.
