A study of school children conducted by University of Rochester Medical Center researchers has found that the majority of children with asthma also reported having allergic rhinitis, or hay fever. Symptoms of hay fever include runny nose, sneezing, congestion and sinus pressure, and can contribute to asthma. The study, led by Jessica Stern, M.D., an assistant professor in the department of Pediatrics and division of Pediatric Allergy and Immunology, found that children with both asthma and hay fever had worse asthma outcomes.
