[Risk factors for bronchial asthma in school children]

To investigate the roles of the residential environment and eating habits in the pathogenesis of bronchial asthma in school children.

One hundred and twenty-nine children between 6-12 years who were diagnosed with asthma were enrolled. Two hundred and fifty-eight healthy age- and gender-matched children were used as the control group. A questionaire which included 23 factors related to respiratory tract anaphylactic diseases such as residential environment and eating habits were completed by the children's parents.

Logistic regression analysis showed that 6 variances out of 16 agents of the residential environment, the experience of raising pets, the type of floor, the type of pillow, the type of quilts, the heating equipments and the house area, were entered into the regression equation; none of the 7 variances of eating inhabits was entered into it.

The residential environment plays an impotent role in the pathogenesis of bronchial asthma in children. The incidence of bronchial asthma in children can be reduced by the improvement of the residential environment.
