Analysis of risk factors of childhood asthma

Objective To analyze risk factors of childhood asthma. Methods Clinical data of 100 cases of children with asthma (case group) aged 0-14 in our hospital from March 2010 to March 2012 were analyzed retrospectively. At the same time, 100 cases of healthy children were selected as control group. Questionnaire survey of asthma related risk factors was carried out to all children, and the results were analyzed in statistics. Results Single factor analysis showed that acute respiratory infection history, family history of asthma, feeling depression, strenuous exercise, breast feeding and decorated houses were related with childhood asthma (P 0.05). Multiple Logistic regression analysis showed that acute respiratory infection history, feeling depression, strenuous exercise and decorated houses were risk factors of childhood asthma; breast feeding was the risk factor of childhood asthma. Conclusion Breast feeding should be advocated, related risk factors should be avoid, and prevention awareness of parents and doctors should be enhanced, in order to prevent childhood asthma.
