婴儿喂养方式与儿童哮喘相关性的前瞻性研究

目的通过婴儿喂养方式与儿童哮喘相关性的前瞻性研究,探讨母乳喂养是否能够减少儿童哮喘的发生率。方法收集我市城镇及农村年龄为6个月内的婴儿3 005例（列入统计者1 442例）,将列入统计者根据喂养方式的不同分为纯母乳组和纯人工组,对两组进行随访,比较两组儿童支气管哮喘发生率。结果纯母乳组有92例诊断为支气管哮喘,哮喘发生率为11.5%;纯人工组有148例诊断为支气管哮喘,哮喘发生率为23.1%。纯母乳组的哮喘发生率明显低于纯人工组,两组哮喘发生率比较差异有统计学意义（P〈0.05）。结论婴儿母乳喂养6个月能够减少儿童哮喘的发生率。

Prospective study of correlation between infant feeding method and child asthma

Objective To investigate whether breastfeeding can reduce the incidence of child asthma through analyzing the correlation between the infant feeding method and the child asthma.Methods 3 005 infants(1 442 infants were included in statistics) aged less than 6 months old in the urban and rural areas of Jieyang City were collected,of which the included infants were divided into the pure breastfeeding group and the pure artificial group according to the feeding method.The two groups were followed up and the incidence of child bronchial asthma was compared between the two groups.Results In the pure breastfeeding group,92 infants were diagnosed with bronchial asthma,with the asthma incidence rate of 11.5%. In the pure artificial group,148 infants were diagnosed with bronchial asthma,with the asthma incidence rate of 23.1%. The asthma incidence rate of the pure breastfeeding group was significantly lower than that of the pure artificial group,with statistically significant difference between the two groups(P<0.05).Conclusion Six months of breastfeeding can reduce the incidence of child asthma.
