Abstract: Objective　To analyze the correlation between the network attention，the actual outpatient volume and the pollen index of allergic rhinitis in children in Beijing based on Baidu index. Methods　The study used Baidu index to search children with allergic rhinitis，and obtained internet attention data in Beijing from January 1，2013 to June 30，2019. 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. Results　（1）From January 1，2013 to June 30，2019，the monthly average network attention of children with allergic rhinitis in Beijing increased year by year. 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）. Conclusion　The network attention of children with allergic rhinitis in Beijing is increasing year by year，and the attention is related to the outpatient volume and meteorological index of pollen allergy.

摘要： 目的　基于百度指数， 对北京地区儿童过敏性鼻炎的网络关注度与真实就诊量及花粉指数进行相关性分析。方法　利用百度指数搜索平台， 以“儿童过敏性鼻炎、 儿童变应性鼻炎”等为搜索关键词， 获取了自2013年1月1日至2019年6月30日间北京地区的网络关注度数据， 同时调取了同一时段每日至首都儿科研究所附属儿童医院就诊并诊断为过敏性鼻炎的患儿数以及中国气象局发布的花粉过敏气象指数， 分析北京地区儿童过敏性鼻炎网络关注度与门诊量、 花粉过敏气象指数间的相关性。结果　（1）自2013年1月1日至2019年6月30日，北京地区儿童过敏性鼻炎的月均网络关注度逐年升高， 依次为1884， 2123， 2475， 2635， 2859， 3001；（2）关注度最高峰均在每年8～9月， 其次为3～6月；（3）关注人群以30～39岁女性为主；（4）每年网络关注度与周门诊量（r值分别为0.804、 0.402、 0.703、 0.762、 0.674、 0.716、 0.545、 0.637， P＜0.05）呈正相关趋势， 2016年、 2018年及2016～2019年整体网络关注度与月花粉过敏气象指数呈正相关趋势（r值分别为0.640、 0.647、 0.391， P＜0.05）。结论　北京地区儿童过敏性鼻炎的网络关注度呈逐年上升趋势， 且关注度与门诊量、 花粉过敏气象指数相关。
