Results: There was no statistically significant difference in the incidence rate of asthma between boys and girls( P 0. 01), the incidence rate of asthma in children with family history of asthma and allergic constitution increased significantly( P 0. 01),the incidence rate of asthma in children with BCG vaccination,immunoglobulin usage,and breastfeeding decreased significantly( P 0. 01). Conclusion: The risk factors of bronchial asthma include family history of asthma and allergic constitution; BCG vaccination,immunoglobulin usage,and breastfeeding are protective factors of bronchial asthma.
