呼和浩特市区儿童肺炎与气象因素关系研究

Correlation between pneumonia and meteorological factors in children from Hohhot

摘要:

目的：探讨呼和浩特市区儿童肺炎发病季节性及其与气象因素的关系，为预防和减少儿童肺炎的发生提供理论依据。方法：以2004年1月至2009年12月5087例呼和浩特市区儿童肺炎住院患儿作为调查对象。应用圆形分布法对肺炎发病进行季节性分析；应用相关分析与多元逐步回归分析调查肺炎发病与各种气象因素之间的关系。结果：儿童肺炎发病有明显的季节性规律，冬春季节多发，高峰在3月份；儿童肺炎发病多于低气温、高气压、降水量少、低湿度、风速偏高的气象条件下发生。结论：气象因素是呼和浩特市区儿童肺炎发病的影响因素，在儿童肺炎的预防工作中应充分考虑其发病的季节特点。

Abstract:

OBJECTIVE: To study the correlation between the morbidity of pneumonia and meteorological factors in children from Huhhot, in order to provide a basis to prevent and decrease the morbidity of childhood pneumonia. METHODS: A total of 5087 hospitalized children with pneumonia from Huhhot between January 2004 and December 2009 were enrolled. The Circular Distribution method was applied to analyze the seasonal characteristics of the morbidity of pneumonia. The Linear Stepwise Regression Analysis was applied to investigate the relationship between the morbidity of childhood pneumonia and meteorological factors. RESULTS: The morbidity of childhood pneumonia displayed an obvious seasonal trend. Childhood pneumonia was common in winter and spring and its peak morbidity was noted in March. The higher morbidity of pneumonia was related to low air temperature, high air pressure, low precipitation, low humidity and high wind velocity. CONCLUSIONS: Meteorological factors affect the morbidity of childhood pneumonia in Hohhot, and should be considered in the prevention of the disease.
