BACKGROUND: Migraine can affect adults during their most productive years, yet few studies in Canada have examined the relationship between migraine-related disability and productivity loss. In particular, the impact of migraine on unpaid productivity loss has not been quantified.
METHODS: In this cross-sectional study, employed adults living with migraine were recruited from across Canada to complete a web-based questionnaire. Migraine-related disability was assessed using the Migraine Disability Assessment questionnaire, and productivity loss was evaluated using the Valuation of Lost Productivity questionnaire. Multiple regression models were used to quantify the association between migraine-related disability level and productivity loss after adjusting for relevant clinical, occupational and sociodemographic covariates.
RESULTS: There were 441 participants, of which 60.1% were female, and the mean (SD) age was 37.7 (10.9). Compared to participants with little to no migraine-related disability, hours of total productivity loss were higher among those with moderate disability (54.1 [95% CI: 10.2-98.1] adjusted hours per 3 months) and severe disability (110.5 [95% CI: 65.5-155.6] adjusted hours per 3 months); paid productivity loss was higher among participants with moderate disability (32.4 [95% CI: 3.1-61.8] adjusted hours per 3 months) and severe disability (61.6 [95% CI: 31.5-91.7] adjusted hours per 3 months); and unpaid productivity loss was greater in those with severe disability (43.5 [95% CI: 12.7-74.3] adjusted hours per 3 months).
CONCLUSIONS: Greater migraine-related disability was associated with more total, paid and unpaid productivity loss among employed adults. These data will be valuable when evaluating the cost-effectiveness of emerging migraine therapies.
