目的:探讨婴儿乳糖不耐受症(lactose intolerance,LI)低乳糖饮品适宜的喂养时间。方法:实验组给予短期低乳糖饮品喂养,对照组给予长期低乳糖饮食喂养。结果:实验组3～6个月的体重增长值、身长增长值、呼吸道感染的患病率、奶粉费用等与对照组相比差异均有统计学意义(P<0.05)。结论:给予乳糖不耐受症婴儿短期低乳糖饮品喂养有利于婴儿的生长发育,维护其免疫功能的稳定,同时又经济实惠,值得各级医疗机构推广。
Objective: To investigate the suitable feeding time of lactose intolerance (LI) low lactose drink. Methods: The experimental group was fed with short-term low-lactose drink and the control group with long-term low-lactose diet. Results: The weight gain, height growth, the prevalence of respiratory tract infection and the cost of milk powder in experimental group were significantly different from those in control group (P <0.05). CONCLUSION: The feeding of short-term low-lactose drinks to infants with lactose intolerance is beneficial to the growth and development of infants, maintaining the stability of their immune function and being economical at the same time. It is worth promoting at all levels of medical institutions.
