【摘要】 目的　分析1996～2001年郑州市大气单因子污染指数(Pi)与上呼吸道感染住院人数(Y)之间的相关性,并找出其中的主要致病污染物。方法　用化学分析法测定大气各污染物,用单纯整群抽样法进行上呼吸道感染住院人数的调查,用多元线性回归和多元逐步回归分析法分析Pi和Y的相关关系,确定主要污染物。结果　1996年～2001年间郑州市大气中各污染物的单因子污染指数PSO2、PNOX、PTSP与Y的相关系数分别为0.496(P=0.000),0.285(P=0.015),0.266(P=0.024),经多元线性回归和多元逐步回归分析提示郑州市大气污染物中SO2与Y有密切关系,PSO2与Y的线性回归方程为Y=35.55+42.55PSO2。结论:郑州市大气污染物中SO2为主要致病因子,PSO2与Y存在线性回归方程。TSP与NOX有协同致病作用。本研究可为医疗卫生部门提供郑州市区上呼吸道感染住院人数的预报,病因分析以及防治措施建议。更多还原

【Abstract】 <Abstrcat>Objective:To study the correlation between air single factor pollution Pi and Y of the infection of the upper respiratory tract in zheng zhou city since 1996,and decide its main pathogenic pollutant substance.Methods: using chemical analysable ways determine each pollutant substance in the air.Using the simple hole sample method investigates Y of the infection of the upper respiratory tract Using pluralism linear regression and pluralism progressive regression analyse the ralationship between pi and Y·Results: From 1996 to 2001,in zhengzhou city the sequence of pollutants by contributing was TSP>NOx>SO2,to pollution The relationship coefficients between PSO2.PNOx.PTsp and .Partly was 0.496(P=0.000),0.285(P=0.015),0.266(P=0.024).Prompted by plualism linear regression and pluralism progressive regression in Zhengzhou City,SO2 and Y in aie pollution has cloesd relationship.TSP and NOx has coordinated action.PSO2 and Ys linear regression equation is Y=35.33+42.55PSO2,Coclusion:In air pollutant substance of zhengzhou City SO2 is the main pathogenic factor PSO2 and Y contain Linear regression equation TSP and NOx has coordinated pathogenic action.This studying can provide the forecast for Y of the inecfion of the upper respiratory tract,the pathogenic analysing and the suggestion about prevention and cure for medical and health departments.更多还原
