A study on the relationship between the number of headaches, quality of life, and labor productivity (Cross-sectional study using receipt data and questionnaire survey results) - A study on the relationship between the number of headaches, quality of life, and labor productivity (Cross-sectional study using receipt data and questionnaire survey results)

The target population was a health insurance association, and approximately 90% of the participants were workers. There was a weak correlation between MHD and MS-QOL. MHD and Absenteeism did not differ by headache day category. WPAI (except Absenteeism) differed between MHD (0-7 days) and MHD (8 or more days). There was a difference in MS-QOL between MHD (0-14 days) and MHD (15 days or more). MHD (0-3 days) also had lower MS-QOL and greater WPAI.
