Objective: To analyze the risk factors of family environment inducing childhood asthma. Methods: Four hundred children with asthma who were diagnosed in outpatient department and inpatient department of the hospital from January 2009 to January 2011 were selected as study objects,the ill children without respiratory tract diseases during the same period were selected as control group.Questionnaire investigation was performed to survey the related factors of childhood asthma. Results: Univariate analysis showed that family history of asthma,family history of allergy,allergic constitution,raising animals,passive smoking,using air-conditioning,exposure to pollen,educational levels of parents,the proportion of often being depressed in asthma group were significantly higher than those in control group(P0.01).Non-conditional multivariate regression analysis showed that family history of asthma,family history of allergy,educational levels of parents,passive smoking,and raising animals had great significances(P0.05). Conclusion: Family history of asthma,family history of allergy,educational levels of parents,passive smoking,and raising animals were risk factors of childhood asthma,which indicate that controlling and correcting the related risk factors of asthma and onset of asthma timely have important actual significances for preventing and controlling asthma.
