目的:探讨不同喂养方式对婴儿体格发育的影响。方法:选择健康婴儿304例,根据出生后前4个月喂养方式分为母乳喂养组、混合喂养组和人工喂养组,测量4月龄时的体重、身长和血骨碱性磷酸酶(BALP)。结果:3组婴儿的体重和身长差异无统计学意义(P>0.05);3组婴儿佝偻病发生率比较差异有统计学意义(P<0.05),母乳喂养组与人工喂养组佝偻病发生率比较差异有统计学意义(P<0.01)。结论:不同喂养方式对4月龄婴儿体重、身长影响差异不大;母乳喂养婴儿补充维生素D不合理,佝偻病发生率会增加,倡导母乳喂养的同时需要合理添加维生素D。
Objective: To investigate the effect of different feeding methods on baby physical development. Methods: A total of 304 healthy infants were selected and divided into breastfeeding group, mixed feeding group and artificial feeding group according to the first 4 months after birth. The body weight, body length and blood alkaline phosphatase (BALP) . Results: There was no significant difference in body weight and body length between the three groups (P> 0.05). The incidence of rickets in the three groups was significantly different (P <0.05). The incidence of rickets in breastfeeding group and artificial feeding group was significantly different There was statistical significance (P <0.01). Conclusion: Different feeding methods have little effect on body weight and body length of 4-month-old infants. Infant vitamin D supplementation in breastfeeding infants is unreasonable and the incidence of rickets is increased. Addition of vitamin D to breast-feeding is reasonable.
