目的：探讨小儿支气管炎与气象因子的关系。方法；对1432例小儿支气管炎发病与气象因子关系分析。结果：发现小儿支气管炎发病与月平均气温、月平均最低气温、月极端最高气温、月平均绝对湿度呈负相关（P＜0．01），与月平均气压呈正相关（P＜0．01）。其原因是住在低温寒冷、于燥、气压增高等气象条件下，易导致：①流感病毒及革兰氏阳性菌繁殖增多；②小儿免疫功能下降；③呼吸道气道阻力增大；④呼吸道纤毛运动减弱等因素有关。结论：建立小儿支气管炎与气象因子的多元回归方程式，可作为预测小儿支气管炎发病趋势的参考指标之一。
Objective: To investigate the relationship between pediatric bronchitis and meteorological factors. Methods; 1432 cases of pediatric bronchitis incidence and meteorological factors. Results: The incidence of bronchitis in children was found to be negatively correlated with monthly average temperature, monthly mean minimum temperature, monthly extreme maximum temperature and monthly mean absolute humidity (P <0.01), and was positively correlated with monthly mean air pressure (P <0.01) . The reason is that living in low temperature and cold, dryness, increased atmospheric pressure and other weather conditions, easily lead to: ① influenza virus and Gram-positive bacteria increased; ② decreased immune function in children; ③ respiratory airway resistance increased; ④ respiratory cilia Exercise and other factors related to the decline. Conclusion: The establishment of multivariate regression equations of pediatric bronchitis and meteorological factors can be used as a reference index to predict the incidence of bronchitis in children.
