摘要
目的分析南充市住院小儿哮喘发作与雾霾及空气质量指数(AQI)的关系。方法以2015至2017年南充市嘉陵区人民医院、南充市中心医院收治的2138例住院儿童为调査对象,其中因哮喘发作住院患儿160例,收集患儿临床相关资料,结合同期环境监测资料[大气中细颗粒物(PM2.5).可吸入颗粒物(PM10).二氧化硫(SO2)、相对湿度、雾霾发生率及AQI],分析该地区住院小儿哮喘发作与雾霾、AQI的关系及小儿哮喘发作的空气污染相关因素。结果2015.2017年南充市PM2.5、PM10、SO2、相对湿度、雾霾发生率、AQI年均值分别为(99.87±10.16)μg/m^3、(110.15±16.57)μg/m^3、(15.17±1.64)μg/m^3、(74.65±7.71)%、(43.17±4.75)%、(124.10±13.17),均有增加趋势;2015、2017年南充市住院患儿哮喘比例分别为5.00%、6.85%、10.16%,呈年增长趋势(Х^2=14.051,P值均<0.05);Spearman相关性分析结果显示,住院小儿哮喘发作与大气中PM2.5、相对湿度、雾霾发生率、AQI呈正相关(r=0.282、0.368、0.351、0.410,P<0.05);单因素及多因素Logistic回归分析结果显示,家属吸烟、未安装排油烟机、与污染源近距离、空气污染分区重度污染、花粉接触史、蠟虫接触史为南充市住院小儿哮喘发作的危险因素(WaldХ^2=7.213、5.787、18.685、5.875、4.544、4.668,P值均<0.05)。结论南充市住院小儿哮喘发作与该市雾霾及AQI存在一定关系,随雾霾程度加重及AQI增加,小儿哮喘发作率上升,应加强环境管理,保障儿童生命健康。
Objective To analyze the relationship between asthma attack and haze,air quality index(AQI)in hospitalized children in Nanchong.Methods A total of 2,138 hospitalized children who were admitted to People's Hospital of Jialing District of Nanchong and Central Hospital of Nanchong during the period from 2015 to 2017 were surveyed,including 160 children hospitalized for asthma attacks.The related clinical data of children were collected.Referring to environmental monitoring data[fine particulate matter in the atmosphere(PM2.5).inhalable particulate matter(PM10),sulfur dioxide(SO2),relative humidity,the incidence of haze and AQI],the relationship between asthmatic attacks and haze,AQI in hospitalized children in the area and air pollution related factors for asthma attacks were analyzed.Results The PM2 5,PM10,SO2,relative humidity,incidence of haze and annual average value of AQI in Nanchong from 2015 to 2017 were(99 87±10 16)μg/m^3,(110.15±16.57)μg/m^3,(15.17±1.64)μg/m^3,(74.65±7.71)%,(43.17±4.75)%and(124.10±13.17),respectively.All of them showed an increasing trend.The asthma ratio of hospitalized children in Nanchong from 2015 to 2017were 5.00%,6.85%and 10.16%,showing an annual increasing trend(Х^2=14.051,PV0.05).Spearman correlation analysis showed that asthma attacks in hospitalized children was positively correlated with PM2.5,relative humidity,incidence of haze and AQI(r=0.282,0.368,0.351,0.410,all P<0.05).Univariate and multivariate Logistic regression analyses showed that the family members smoking,do not install the smoke exhaust ventilator,close to the pollution source,severe air pollution,history of contact with pollen and mites were risk factors for asthma attacks in hospitalized children in Nanchong(WaldХ^2=7.213,5.787,18.685,5.875,4.544,4.668,all P<0.05).Conclusions There's a certain relationship asthma attacks in hospitalized children in Nanchong and haze,AQI in the city.With aggravation of haze and the increase of AQI,the incidence of asthma attacks in children increases.Therefore,environme
