Fifty infants less than 1 year of age with rotavirus gastroenteritis were studied with regard to the protective effect of breast-feeding. The initial incidence of breast-feeding was 64% in the patients infected with rotavirus and 70% in a matched control population. Seven patients were breast-fed at the time of infection, 25 patients had stopped breast-feeding prior to infection, and 18 patients were exclusively formula-fed. There were no significant differences between groups in the average age of infection, mean duration of diarrhea, mean number of bowel movements in 24 hours, or in the frequency of fever or irritability. The only apparent difference between groups was that the frequency of vomiting was significantly decreased in the breast-fed children. The results of this study suggest that breast-feeding offers little protection against rotavirus gastroenteritis.
对50名1岁以下感染轮状病毒胃肠炎的婴儿进行了母乳喂养保护作用的研究。感染轮状病毒的患者中母乳喂养的初始发生率为64%，在匹配的对照人群中为70%。7名患者在感染时进行母乳喂养，25名患者在感染前停止母乳喂养，18名患者完全采用配方奶喂养。各组在平均感染年龄、腹泻平均持续时间、24小时平均排便次数、发热或烦躁频率方面无显著差异。各组之间唯一明显的差异是母乳喂养儿童的呕吐频率显著降低。本研究结果表明，母乳喂养对轮状病毒胃肠炎几乎没有保护作用。
