Background:
Disability imposed by headache disorders constitutes an expressive economic burden, mostly from indirect costs due to absenteeism and presenteeism.
Objective:
To estimate indirect costs from absenteeism and presenteeism due to headache disorders in Brazil.
Methods:
In a secondary, descriptive analysis of two nationwide databases, we estimated indirect costs based on headache-related disability and socioeconomic data.
Results:
In the first database analyzed (n = 3838), 12.8% of the employed population with headache disorders missed at least 1 day of work in the last 3 months (mean, 95% CI = 4.2 days [3.7-4.6]). Based on the prevalence of headache disorders, days lost due to headaches and income data, R$ 40.4 billion (Int$ 20 billion) are lost due to headache-related absenteeism annually. For presenteeism, 26.2% of the employed population with headache disorders worked at least 1 day in the last 3 months with 50% reduced productivity (mean, 95% CI = 5.7 days [5.3-6.2]), amounting to R$ 27.3 billion (Int$ 13.5 billion) of financial loss annually. In the other database analysed (n = 205,546), 14,052 (6.8%) respondents missed work/school or household duties in the past 2 weeks due to some disease. Of these, 4.7% attributed their days lost to headaches disorders in the economically active population, which ranked 4th as main cause of days lost due to disease, among 23 common diseases.
Conclusions:
The economic burden of headache disorders in Brazil, mostly due to migraine (55.4%), may cost up to R$ 67.6 billion (Int$ 33.5 billion) annually, and headache disorders represent a leading cause of absenteeism due to disease.
