BACKGROUND
Asthma has been linked to stroke, but it is unknown if hay fever is related to stroke. This study was designed to investigate if there is an association between a reported history of hay fever and stroke during a 4.4-year study period.
METHODS
Analysis was performed of the Atherosclerosis Risk in Communities study, a cohort of middle aged and elderly adults. We examined the association of a reported history of hay fever to the development of stroke.
RESULTS
There were 9272 participants meeting our criteria, of which 125 had strokes. Of those with a history of hay fever, 2.2% had a stroke. Of those without a history of hay fever, 1.25% had a stroke. Participants with a history of hay fever had an unadjusted hazard ratio of 1.72 (95% CI, 1.08-2.27) for stroke versus participants without hay fever. Risk of stroke remained significant (hazard ratio, 1.87 [95% CI, 1.17-2.99]) after controlling for age, sex, race, smoking status, body mass index, diabetes, hypertension, alcohol use, and hyperlipidemia.
CONCLUSIONS
A history of hay fever seems to be a risk factor for stroke, and this association may be an area for future research and intervention.
