Purpose: Various studies have investigated factors related to the prevalence of allergic rhinitis (AR). We studied the correlation between the outbreaks of AR and airborne pollen in September.
Methods: According to data from the National Health Insurance Service, the number of AR cases was increased from 2012 to 2016. During the same period, the number of patients with upper respiratory tract infection, respiratory virus detection rate, air pollutants, and concentration of airborne pollen were correlated with the occurrence of AR in correlation analysis.
Results: The number of patients with AR showed increasing biphasic patters in the spring and fall with the peak reached in September (278,487±12,894), while April marked the fifth-highest figure with 241,570±132,677. The concentration of airborne pollen was highest at 4,450 grains/m3 in May, followed by 3,597 grains/m3 in April, marking its peak in the spring. September marked the third-highest level at 1,619 grains/m3. According to the monthly correlation between the number of patients with AR and pollen, Seoul and Daejeon showed correlations of ρ=0.929 (P=0.022) and ρ=0.955 (P=0.011), respectively, in September. There were no significant correlations among AR, air pollutants, and respiratory virus detection rate.
Conclusion: Based on this study, the monthly number of patients with AR was the highest in September. In September, we found the correlation between allergic rhinitis and pollen, although there are regional limitations, regarding outbreaks in the number of patients with AR. Further research and attention are needed to prepare measures against airborne weed pollen during the fall.
