不同喂养方式对婴儿发生反复呼吸道感染的影响

Effect of different feeding patterns on infants with recurrent respiratory tract infections

目的探讨不同喂养方式对婴儿呼吸道感染性疾病发生及转归的影响。方法对2008年1月至2009年12月江门市结核病防治所门诊治疗的0-12月龄的呼吸道感染性疾病的患儿,按喂养方式分为纯母乳喂养组、混合喂养组和人工喂养组,分析其呼吸道感染性疾病的发生率和预后情况,观察其相关性。结果纯母乳喂养的婴儿其呼吸道感染性疾病发病率明显低于其他两组（χ^2=58.84,P〈0.01）,尤低于人工喂养的婴儿（χ^2=8.075,P〈0.01）;在有呼吸道感染性疾病的患儿中,纯母乳喂养和混合喂养的婴儿呼吸道感染天数较同期的人工喂养婴儿少（χ^2=21.00,P〈0.05;χ^2=25.24,P〈0.01）,慢性呼吸道症状也较少发生。结论母乳喂养有利于减少婴幼儿呼吸道感染性疾病的发生,并缩短其病程。

Objective To study the incidence of respiratory tract infections and prognosis implications of different feeding pat-terns on infants. Methods From January 2008 to December 2009,0 to 12 months children with respiratory tract infection were di-vided into exclusive breast feeding group,mixed feeding group and the artificial feeding group by feeding,the incidence of respira-tory tract infections and prognosis implications of the three group were analyzed,and examined their relevance. Results The inci-dence of respiratory tract infection of exclusive breastfeeding group was significantly lower than that of the other two groups（χ^2 =58. 84,P ﹤0. 01）,especially lower than that of artificial feeding group（χ^2 =8. 075,P ﹤0. 01）;During the respiratory tract infec-tious diseases in children,the number of days of exclusive breastfeeding group and mixed feeding group were less than those of arti-ficial feeding group（χ^2 = 21. 00,P ﹤ 0. 05;χ^2 = 25. 24,P ﹤ 0. 01）,and the chronic respiratory symptoms occurred was less. Conclusion The breastfeeding infants are good to reduce the incidence of respiratory tract infection,but also shorten its duration.
