Abstract:
Objective To explore the correlated risk factors of infants with severe bronchiolitis.Methods Two hundred and nine bronchiolitis children were enrolled in this study.According to the severity of the disease,children were divided into common group (n =182) and severe group (n =27),and then monofactorial analysis and non-conditional logistic analysis were performed to evaluate the risk factors in children with severe bronchiolitis.Results Monofactorial analysis showed that six variables were found on the occurrence of severe bronchiolitis with statistical significance including age (t =3.455 ; P =0.001),passive smoking (x2 =6.119 ; P =0.013),prematurity (x2 =17.124 ; P =0.000),obesity (x2 =5.673 ; P =0.017),allergic constitution (x2 =5.736 ; P =0.017),and congenital heart disease (x2 =20.694; P =0.000).Non-conditional logistic analysis showed that frequent occurrence of young age (OR 0.742 ; 95 ％ CI 0.601 ～ 0.917),passive smoking (OR 3.300 ;95 ％ CI 1.060 ～ 10.276),prematurity (OR 5.265 ;95 ％ CI 1.565 ～ 17.705) and congenital heart disease(OR 13.634 ;95％ CI 3.015 ～ 61.663)were the risk factors in children with severe bronchiolitis.Conclusion The factors that contribute to increase risk of severe bronchiolitis are young age,passive smoking,prematurity,allergic constitution and congenital heart disease.
