北京秋冬季空气质量指数与老年变应性鼻炎门诊量的短期相关性研究

摘要

Objectives To determine the short term relationship between the number of old allergic rhinitis(AR) patients and the air quality index(AQI) data in autumn and winter in Beijing.Methods Between October 2015 and December 2015,the AQI index data and the number of old outpatients with AR in Beijing Hospital were collected and the relation between them was evaluated by Pearson correlation analysis.Results The AR patients aged over 60 were 1 892 cases (36.72％ of the total number of outpatients).The males were 953 (50.4％),The females were 939 (49.6％).The number of old outpatients with AT changed from 4/d to 39/d.When the AQI rised,the total number of old outpatients was increased;however,when the AQI rised to a certain extent,especially to the serious pollution value (＞300),the number of old outpatients was declined.Pearson correlation analysis showed that there was a negative correlation between the amount of old AR patients and the AQI in the high incidence of air pollution seasons in Beijing (r=0.311,P＜0.01).Conclusions Air pollution is one of the most important reasons for the increased rate of AR patients in the elderly.%目的 研究北京市秋冬季空气质量指数与老年变应性鼻炎(AR)门诊量的短期相关性. 方法 统计2015年10月至12月北京医院耳鼻咽喉头颈外科的老年AR门诊量与同期北京AQI指数进行综合分析. 结果 ≥60岁AR患者1892例(约占同期总患病数36.72％),其中男953例,女939例,比例为1∶1.老年AR门诊量在4～39例/d区间变化.当AQI指数上升时,当日AR门诊量总数相应上升,当AQI指数上升到一定程度,尤其是上升达到严重污染数值(＞300),当日变应性鼻炎门诊量却有所下降.在空气污染高发季节变应性鼻炎门诊量与AQI指数呈一定程度的负相关性(r=-0.311,P＜0.01). 结论 空气污染是老年AR患者增加的重要原因之一.
