目的:了解不同喂养方式对两月龄婴儿生长发育的影响。方法:通过选取北京市某些社区儿童保健手册中两月龄婴儿喂养记录及体检了解婴儿的喂养情况。结果:三种喂养方式下的两月龄婴儿体重、身长的差异具有统计学意义。人工喂养的两个月婴儿体重大于母乳喂养的,母乳喂养的两个月婴儿身长大于混合喂养和人工喂养的婴儿,P<0.05。三种喂养方式对两月龄婴儿贫血的发病率没有显著的影响,母乳喂养下两个月龄婴儿的精细动作-适应性通过率高于其他两种喂养方式。结论:母乳喂养对两月龄婴儿生长发育某些方面的影响优于人工喂养和混合喂养。 Objective: To understand the effects of different feeding methods on the growth and development of two-month-old infants. Methods: To understand the feeding status of infants through selecting two-month-old infant feeding record and physical examination in some community health care manuals in Beijing. Results: The differences of body weight and body length of two-month-old infants under three feeding modes were statistically significant. Two-month, artificially fed infants were heavier than breastfeeding and two months of breastfeeding infants older than mixed and artificially infants, P <0.05. The three feeding regimens had no significant effect on the incidence of anemia in two-month-old infants, and the fine motor motivation of two-month-old infants under breastfeeding - the adaptive pass rate was higher than the other two feeding regimes. CONCLUSIONS: Breastfeeding had a greater effect on certain aspects of two-month-old infants than artificial feeding and mixed feeding.
