2014年江阴市手足口病与气象因素相关分析

Correlation between Hand-Foot-Mouth Disease and Meteorological Factors in Jiangyin City in 2014

目的探讨江阴市手足口病的发病情况与气候因素的关系。方法收集2014年江阴市手足口病日发病数据和同期气象资料,包括日平均气温、平均气压、风速、相对湿度和日照时间。运用SPSS22.0软件对气象因素与手足口病发病资料进行单因素和多因素线性回归分析。结果手足口病好发于春夏季,4-7月为发病高峰。单因素相关分析显示,手足口病日发病数据与气温正相关(r=0.567,P<0.01),与气压负相关(r=-0.613,P<0.01),而与风速、相对湿度和日照时间无相关关系(P>0.05)。结论高气温、低气压的气象条件是手足口病发病的危险因素。气象条件与手足口病发病的关系对科学防控手足口病具有重要意义。

Objective To analyze the correlation between meteorological factors and incidence of Handfoot-mouth disease(HFMD).MethodsIncidence data of HFMD cases in 2014 and meteorological data average temperature,barometric pressure,wind speed,relative humidity and sunlight in the same period were collected and analyzed by univariate and multivariate linear regression for the correlation between meteorological factors and incidence of HFMD.ResultsThe cases were highly incident in spring and summer,and the occurrence reached the peak during April to July.The incidence of HFMD positively correlated with temperature(r=0.567,P <0.01)and negatively correlated with barometric pressure(r=-0.613,P<0.01).However,no correlation was found between incidence of HFMD and wind speed,relative humidity and sunlight(P>0.05).ConclusionHigh temperature and low barometric pressure are risk factors for incidence of HFMD.Understanding the relationship between meteorological factors and epidemic trend of HFMD is of great significance for preventing and controlling HFMD efficiently.
