大气污染与儿童急性中耳炎、急性扁桃体炎就诊人数的相关性调查

Correlations Between Air Pollution and Number of Patients of Acute Otitis Media and Acute Tonsillitis in Children

目的探讨空气污染与解放军第306医院儿童急性中耳炎、急性扁桃体炎就诊人数之间的相关性。方法收集2015年1月1日-2015年12月31日期间该院所有儿童急性中耳炎、急性扁桃体炎的门诊与急诊病例及此期间的空气质量指数(air quality index,AQI)及6项大气污染物空气质量指标(由北京市环境监测中心提供),并进行相关性分析。结果儿童急性中耳炎、急性扁桃体炎与PM2.5、PM10、SO_2、CO、NO_2间具有相关性。对于全年数据分析儿童急性中耳炎相关性以SO_2、CO、NO_2较明显,对于儿童急性扁桃体炎相关性以CO、PM10、NO_2、PM2.5较明显。结论冬春季儿童急性中耳炎、急性扁桃体炎日就诊人数与AQI、PM2.5、SO_2、CO、NO_2的相关性远高于夏秋季,以累积3日相关性最好,从而推测大气污染与两种疾病的发生密切相关。

Objective To study the correlations between air pollution and the number of children with acute otitis media and acute tonsillitis treated at the 306th Hospital of PLA. Methods Clinical data was collected on children with acute otitis media and acute tonsillitis treated at our hospital between Jan 1,2015 and Dec 31, 2015. The AQI and six atmospheric pollutant inde- xes during the same period were also analyzed. Results The incidence of acute otitis media and acute tonsillitis in children was correlated with levels of PM2.5 ,PM10 ,SO2 ,CO andNO2. There was a high correlation between acute otitis media and levels of SO2 ,CO,NO2 while acute tonsillitis was linked to levels of PM2.5 ,NO2 ,CO and PM10. Acute otitis media and acute tonsillitis were more significantly correlated with these indexes in winter than in summer. Cumulative 3 days had the best correlation. Condusion Air pollution might be closely related to the occurrence of the two diseases.
