目的探讨烟气暴露对儿童呼吸系统的影响。方法对2009年6月～2011年6月某院收治的174例3～6岁患呼吸系统疾病患儿进行了系统调查。采用家长填写问卷的方式,调查内容主要包括家长每日吸烟量及吸烟年限。结果烟气暴露儿童感冒、肺炎、支气管炎、哮喘发病率显著高于无烟气暴露的儿童(P﹤0.05);家庭成员的每日吸烟量和吸烟年限与儿童呼吸系统疾病发生率呈正相关(P﹤0.05)。结论烟气暴露与儿童呼吸系统疾病的发生密切相关,家庭成员尽早戒烟可有效减少对儿童呼吸系统的影响。
Objective To explore the effects of smoke exposure on children’s respiratory system. Methods A total of 174 children aged 3 to 6 years with respiratory diseases admitted in a hospital from June 2009 to June 2011 were systematically investigated. The questionnaire was filled in by parents. The survey mainly included the daily smoking amount and smoking years of parents. Results The incidence of colds, pneumonia, bronchitis and asthma in children exposed to smoke was significantly higher than that in children without smoke exposure (P <0.05). The daily smoking and smoking duration of family members were positively correlated with the incidence of respiratory diseases in children P <0.05). Conclusions Smoke exposure is closely related to the occurrence of respiratory diseases in children. Quitting smoking as soon as possible by family members can effectively reduce the impact on children’s respiratory system.
