  • BackgroundHeadache is a common condition, and a common complaint leading patients to emergency departments (ED). There have been a number of studies of the effect of environmental factors on headache, such as weather and air pollutants.MethodsThis retrospective cohort study included data on daily ED visits with a chief complaint of headache in Soroka University Medical Center (SUMC) during 2002–2012. Data on weather and air pollutants were obtained from monitor station in Be'er-Sheva. To estimate the short-term effects of air pollution and temperature on number of daily headache ED visits, we applied generalized linear mixed models (GLMM).ResultsA total of 22,021 ED visits were included in the analysis. An increase in 5℃ in temperature was associated with an increase in ED visits, relative risk (RR) = 1.042, (95% CI 1.009; 1.076). RR for headache was associated with an increase in 10 units of nitrogen dioxide (NO2), RR = 1.110 (95% CI 1.057; 1.167), with a higher effect for older patients.DiscussionThe cu...
