Abstract：Objective To explore the current status of airborne pollen and analyze its correlation with the occurrence of allergic rhinitis (AR) in urban area of Panzhihua City so as to provide a basis for AR diagnosis, treatment and prevention of local patients. Methods The samples were collected on the fifth-floor roof of anatomy building in Clinical Medicine Department of Panzhihua University by standardized air pollen sampler from May 2021 to May 2022. The sampling was performed by gravity sedimentation method to record species and quantity of pollen. 180 AR outpatients treated in otolaryngology department of Panzhihua Hospital of Integrated Traditional Chinese and Western Medicine from May 2021 and April 2022 were selected as the research subjects. All patients underwent skin tests by prick solution, and then they were inquired about the onset seasons. The AR patients’ disease severity was evaluated by visual analogue scale (VAS). Pearson correlation analysis was performed to ascertain the relationship between the content of monthly airborne pollen and the number of monthly onset cases. ResultsBroussonetieae pollen accounted for 59.56% of the total pollen in the whole year, which was the absolutely dominant airborne pollen in Panzhihua City, followed by Moraceae pollen (17.15%) and Cannabis/Humulus pollen (4.37%). The content of airborne pollen in Panzhihua City was the lowest in December, and then gradually increased since February. The first peak occurred in March-April, and then basically disappeared in June. The second peak happened in September-October, but the content of airborne pollen was the lowest in winter. The main onset seasons in the AR patients were March, April, September and October, which were consistent with the dissemination peak of airborne pollen in Panzhihua City. The content of monthly airborne pollen was positively correlated with the number of monthly onset cases (r=0.972, P<0.001). The AR patients’ VAS scores were found to be significantly higher in the months with higher content of airborne pollen, but their VAS scores were significantly lower in the months with lower content of airborne pollen. Conclusion The dominant airborne pollen grains in Panzhihua City include Broussonetieae pollen, Moraceae pollen and Cannabis/Humulus pollen, and there are two peaks, occurring in March-April and September-October. The AR patients’ onset seasons are consistent with the dissemination peak of airborne pollen, suggesting that the content of airborne pollen is correlated with AR onset.
