This study evaluated the coexistence of asthma and allergic rhinitis in adult patients attending allergy clinics. Over a 10-year follow-up period, 1,271 college freshmen were prospectively evaluated for medical conditions including asthma and allergic rhinitis. The results showed that the frequency of asthma and allergic rhinitis continued to increase as the individuals became older. Allergic rhinitis and positive allergy skin tests were significant risk factors for developing new asthma. Individuals with either of these diagnoses were about three times more likely to develop asthma over the 10-year period than those with negative skin tests.
