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 investigate the relationship between the incidence of hand-foot-mouth disease and climatic factors in Jiangyin City. Methods The incidence data of hand-foot-mouth disease in Jiangyin in 2014 and the meteorological data of the same period were collected, including the average daily temperature, average air pressure, wind speed, relative humidity and sunshine time. SPSS22.0 software was used to analyze the data of meteorological factors and hand-foot-mouth disease by single factor and multi-factor linear regression analysis. Hand-foot-mouth disease occurs in spring and summer, peak from April to July. Univariate correlation analysis showed that the data of hand-foot-mouth disease onset was positively correlated with air temperature (r = 0.567, P <0.01) and negatively correlated with air pressure (r = -0.613, P <0.01) No correlation (P> 0.05). Conclusion The meteorological conditions of high temperature and low pressure are the risk factors for HFMD. The relationship between meteorological conditions and the incidence of HFMD is of great importance for the prevention and control of HFMD.
