Abstract

This study reports on a clinical and statistical examination of 628 outpatients who visited our medical department and were diagnosed with allergic rhinitis in the six years between 1996 and 2001. Among all patients, 46.5% suffered from nasal allergy with mites, 42.4% had Japanese cedar pollinosis, and 46.7 % of patients had grass weed pollinosis. Grass weed pollinosis was most common and pollinosis tended to shift into a much older generation. With regard to patients with Japanese cedar pollinosis under the age of 19, there were significantly more male than female patients. Among grass weed pollinosis sufferers under age 29 also male patients outnumbered females. Japanese cedar pollinosis and grass weed pollinosis patients had serious grade symptoms significantly more commonly in environments where air pollution in the daytime was much worse than elsewhere, and it is worth noting that more than 50% of patients had lower airway symptoms.
