目的评价陕西省神木县气象因素与儿童下呼吸道感染住院人数的关系.方法收集2009年1月至2012年12月神木县气象因素(气温、气压、降雨量、光照时间、风速和相对湿度)及≤16岁儿童的住院资料.利用SAS 9.3对气象、下呼吸道感染住院人数、总住院人数和下呼吸道感染住院率进行描述性分析.了解各气象因素与下呼吸道感染住院率之间的相关程度,并探讨气象因素与下呼吸道感染住院率之间相关性.结果纳入研究的对象19 772例,其中下呼吸道感染住院患者4 449例,占 22.5％下呼吸道感染住院率与气温(r=-0.651,P＜0.001)、气压(r=0.560,P＜0.001)、降雨量(r=-0.614,P ＜0.001)和相对湿度(r=-0.470,P＜0.001)呈显著相关,而与光照强度、风速无相关性.多重线性回归分析发现,下呼吸道感染住院率随着平均气温和平均湿度的上升而逐渐下降(F=38.30、15.58,P均＜0.001). 结论平均气温和平均湿度是影响神木县儿童下呼吸道感染住院率的主要气象因素.

Objective To evaluate the relationship between Shenmu County's meteorological factors and the number of children's hospitalization due to lower respiratory tract infection.Methods Data collection was performed during Jan.2009 to Dec.2012,concerning Shenmu countv's meteorological factors (temperature,pressure,rainfall,light intensity,wind velocity and relative humidity)for the hospitalization of children under 16 years of age.The statistical software SAS 9.3 was used to detect and analvze the correlations of the lower respiratory tract diseases with the hospitalization rate with respect to meteorological factors,and to compare the total number of hospitalization due to lower respiratory tract diseases.Degree of correlation and the regression relationship were explored among various meteorological factors and the rate of hospitalization because of respiratory infections.Results There were 19 772 patients in this study,including 4 449 lower respiratory tract infection hospitalizations,accounting for 22.5％.The hospitalization rate of lower respiratory tract infection was significantly associated with air temperature (r =-0.651,P ＜ 0.001),barometric pressure(r=0.560,P＜0.001),rainfall (r=-0.614,P＜0.001) and relative humidity (r=-0.470,P＜0.001),while it was not statistically associated with the light intensity and the wind velocity.Multiple linear regressions indicated that the lower respiratory tract infection hospitalization rate decreased with the gradual increase of temperature and relative humidity(F =38.30,15.58,all P ＜ 0.001).Conclusion Temperature and relative humidity are the major influencing factors for lower respiratory tract infection hospitalization rate in Shenmu County's children.
