[Objective] To study the relationship between the childhood asthma and the potential risk factors in the living environment.
[Methods] One thousand nine hundred and forty-one primary and high school students were randomly stratified sampled to participate in the survey.
[Results] Univariate analysis indicated premature delivery, the family allergic history and living in the room newly decorated in 3 months were the risk factors of childhood asthma. Multivariate analysis revealed that among the three risk factors, room decoration P=0.001, OR=0.277; the premature delivery P<0.05, OR=1.537; and the family allergic history P<0.001, OR=0.784.
[Conclusion] Living in the room newly decorated in 3 months may easily induce the childhood asthma, so that the newly decorated rooms should be ventilated more than 3 month before moving in.
