Employees from a Brazilian oil company reserach centre (n=993) were interviewed on the occurrence of headache during a 30 days period. Headache prevalence was 49.8%, with a mean frequency of 4 3±7.0 attacks per month, lasting 12.2±21.4 hours each. According to the International Headache Society diagnostic criteria, migraine (5.5%), episodic tension-type headache (26.4%), chronic tension-type headache (1 7%) and headaches not fulfilling the criteria for such disorders (16.2%) were observed. Women suffered comparatively more headache and specifically migraine than men The pain interfered with work productivity in 10% of the subjects, corresponding to 538 75 hours off. According to an indirect costs estimation for each headache, the company may loose up to US$125.98 per employee annually. Since among headaches migraine has the highest indirect cost, migraine prevention and treatment is particularly important at the working environment Migraine frequency may be prevented to a large extent, resulting on positive effects in both the quality of life and productivity. The cost-benefit ratio clearly favours therapeutic and preventive programs against chronic headaches.
