407 Survey of Rhinitis Phenotypes

agnosed children and adults, respectively, were: 13 and 15 times greater for acute respiratory infection; 6 and 9 times greater for otitis media; 6 and 8 times greater for asthma; 6 and 12 times greater for upper respiratory infection; 5 and 8 times greater for conjunctivitis; 5 times greater (both children and adults) for chronic obstructive pulmonary disease/allied conditions; 5 and 8 times greater for strep throat; 4 and 3 times greater for pneumonia/influenza; and 4 and 9 times greater for atopic dermatitis. Differences between ARversus nonAR-diagnosed groups and between children and adults were significant at the P , 0.001 level. Conclusions: Compared to their counterparts who were not diagnosed with AR, children and adults with AR had a significantly greater likelihood for receiving any targeted comorbid allergy-related respiratory condition. Likelihood estimates, which were 3 to 15 times greater for AR-diagnosed patients, varied significantly for children and adults by specific comorbid condition. Given a diagnosis of AR, the likelihood for comorbid respiratory infection, asthma, otitis media, conjunctivitis, atopic dermatitis and strep throat was substantially greater for adults; the likelihood for pneumonia/ influenza was greatest for children; and the likelihood for chronic obstructive pulmonary disease/allied condition was roughly equivalent for the 2 age groups.
