Abstract: 【Objective】 To analyze the environmental factors that might affect chronic cough in children,especially those living environment for the etiology of chronic cough in children and to provide intervention clues. 【Methods】 October 2006~April 2011,3~14 years children diagrosed chronic cough(observer group 102 cases,control group of 143 cases),basic materials included respiratory infections family tobacco exposure,an allergy per capita dwelling space,indoor decoration and indoor pets,planting flowers were collected to analyze. 【Results】 After the intervention,children cough frequency changes had taken place,observer group decreased significantly,with were differences obvious of two group (χ²=13.05,P<0.01).Logistic regression analysis showed:respiratory infection family of tobacco exposure,indoor decoration too,indoor pets as the major factors influencing chronic cough in children. 【Conclusion】 For children with chronic cough,we should increase the prevention of respiratory tract infection,avoid indoor tobacco exposure,control room excessive decoration and indoor pets sparingly.

摘要： 【目的】 对可能影响儿童慢性咳嗽的环境因素,特别是生活环境进行分析,为儿童慢性咳嗽的病因学研究和干预提供线索。 【方法】 对2006年10月-2011年4月符合慢性咳嗽诊断标准的3~14岁的儿童,观察组102例,对照组143例的基础资料包括呼吸道感染,家庭烟草暴露,过敏史,人均居住面积,室内装潢及室内养宠物、养植花草等因素进行分析。 【结果】 采取干预措施后,两组儿童咳嗽的频率都发生了变化,观察组明显下降,两组具有明显的差异性(χ²=13.05,P<0.01)。Logistic回归分析显示:家庭烟草暴露,呼吸道感染,居室装潢过度,室内养宠物为影响儿童慢性咳嗽的主要因素。 【结论】 对慢性咳嗽的儿童,应加大呼吸道感染的预防,避免室内烟草暴露,控制居室装潢过度,室内尽量少养宠物。
