“…This review builds upon limited existing work summarizing associations between air pollution and migraine and/or headache. [13][14][15] Specifically, we believe this review represents the first systematic search for studies of air pollution and migraine, assessment of risk of bias, and synthesis of the available data. Reflecting the studies to date, our review includes short-and long-term studies and a wide variety of air pollution exposures and migraine outcomes.…”

ObjectiveTo systematically synthesize evidence from a broad range of studies on the association between air pollution and migraine.BackgroundAir pollution is a ubiquitous exposure that may trigger migraine attacks. There has been no systematic review of this possible association.MethodsWe searched for empirical studies assessing outdoor air pollution and any quantified migraine outcomes. We included short‐ and long‐term studies with quantified air pollution exposures. We excluded studies of indoor air pollution, perfume, or tobacco smoke. We assessed the risk of bias with the World Health Organization's bias assessment instrument for air quality guidelines.ResultsThe final review included 12 studies with over 4,000,000 participants. Designs included case‐crossover, case–control, time series, and non‐randomized pre–post intervention. Outcomes included migraine‐related diagnoses, diary records, medical visits, and prescriptions. Rather than pooling the wide variety of exposures and outcomes into a meta‐analysis, we tabulated the results.Point estimates above 1.00 reflected associations of increased risk. In single‐pollutant models, the percent of point estimates above 1.00 were carbon monoxide 5/5 (100%), nitrogen dioxide 10/13 (78%), ozone 7/8 (88%), PM2.5 13/15 (87%), PM10 2/2 (100%), black carbon 0/1 (0%), methane 4/6 (75%), sulfur dioxide 3/5 (60%), industrial toxic waste 1/1 (100%), and proximity to oil and gas wells 6/13 (46%). In two‐pollutant models, 16/17 (94%) of associations with nitrogen dioxide were above 1.00; however, more than 75% of the confidence intervals included the null value.Most studies had low to moderate risks of bias. Where differences were observed, stronger quality articles generally reported weaker associations.ConclusionsBalancing the generally strong methodologies with the small number of studies, point estimates were mainly above 1.00 for associations of carbon monoxide, nitrogen dioxide, ozone, and particulate matter with migraine. These results were most consistent for nitrogen dioxide.
