Abstract:

Objective To investigate the onset patterns of pollinosis, and to analyze the correlation between onset time of pollinosis patients and atmospheric pollen concentration. Methods A total of 14 426 cases that were diagnosed with allergic rhinitis(AR) underwent a skin prick test, pollen allergens and the onset patterns were assessed. Pollen concentration and category in Beijing area were monitored from March to September every year. The correlation between onset patterns of pollinosis patients and atmospheric pollen concentration were analyzed. Results In 14 426 cases of skin prick test positive patients, 8 127 had pollinosis(55.9%); The main age of pollinosis patients were generally 15-18 and 31-40 years of age. The onset time of pollinosis patients showed significant correlation with pollen concentration(r=0.787, P<0.01). Conclusion Pollens are important allergens of AR; onset time of pollinosis patients was significantly associated with the pollen concentration, these results can make a basis for prediction of pollinosis.
