Meanwhile，the authors obtained the daily outpatient volume of children who were diagnosed as allergic rhinitis in Children’s Hospital Affiliated to Capital Institute of Pediatrics in the same period of time. According to the meteorological index of pollen allergy released by China Meteorological Administration，the authors analyzed the correlation between the network attention of children with allergic rhinitis in Beijing and the outpatient volume and the meteorological index of pollen allergy.

The Baidu index were 1884，2123，2475，2635，2859，3001；（2）The peak of attention was from August to September every year，followed by March to June；（3）The focus group was mainly women aged 30-39；（4）There was a positive correlation between the annual network attention and weekly outpatient volume（r values were 0.804，0.402，0.703，0.762，0.674，0.716，0.545，0.637，P＜0.05）. And there was a positive correlation between overall network attention and monthly meteorological index of pollen allergy in 2016，2018 and 2016-2019（r values were 0.640，0.647，0.391，P＜0.05）.
