根据空气污染数据对广州、武汉、兰州、重庆4城市8个点位进行了空气污染的聚类分析,并按空气污染程度进行了排序.在此基础上,分析了空气污染程度与儿童及其父母呼吸系统健康的关系.发现儿童11种患病率随空气污染程度加重而呈上升趋势.污染最重组的患病率是污染较轻组的1.71(3.95倍.污染最重组的比数比(即OR值)是污染较轻组的3.313(6.942倍.空气污染对儿童父母的呼吸系统患病率也有轻度至中度的影响.
According to the air pollution data, the cluster analysis of air pollution in 8 spots in Guangzhou, Wuhan, Lanzhou, Chongqing and 4 cities was carried out, and the air pollution was sorted according to the degree of air pollution.On the basis of this, the relationship between air pollution degree and children and their The relationship between respiratory system health of parents and children found that 11 kinds of prevalence increased with the degree of air pollution increased.The prevalence of the most severe pollution was 1.71 (3.95 times the pollution of the most polluted than the ratio ( OR) was 3.313 (6.942-fold) in the less-polluted group Air pollution also had a mild to moderate effect on the respiratory rate of children’s parents.
