Air Pollution and Daily Emergency Department Visits for Migraine and Headache in Edmonton, Canada

Szyszkowicz M, Stieb DM, Rowe BH

In this study, the authors “analyzed associations between air pollution and emergency department (ED) visits for migraine and headache.”

The study found that, “An interquartile range (IQR) increase (6.2 microg/m3) in daily average particulate matter of median aerodynamic diameter less than 2.5 microm (PM2.5) was associated with increases in visits of 3.3% for migraine (95% confidence interval [CI]: 0.6-6.0), lagged 2 days, and 3.4% for headache (95% CI: 0.3-6.6), lagged 0 days, among females in the cold season (October-March). PM2.5 was also associated with cold season migraine visits among females at lag 0 and 1 day (P < .1).”

The authors conclude, “Findings provide preliminary evidence of an association between air pollution and E[mergency]D[epartment] visits for migraine and nonspecific headache. Findings were most consistent for particulate matter.”
