目的观察不同喂养方式对婴儿身长、体重的影响。方法选择2005年3月～2006年3月出生的小儿282例,42d来院儿科早期教育门诊体检,按喂养方式分成3组:母乳喂养组140例,混合喂养组102例,人工喂养组40例,进行身长、体重的测量。结果3组婴儿出生时体重与身长差异均无显著性(P>0.05);生后42d纯母乳喂养组的身长、体重增长数均明显高于混合喂养组及人工喂养组(P<0.01);混合喂养组42d时身长的增长与人工喂养组比较差异无显著性(P>0.05),但体重的增长较人工喂养组增大(P<0.01)。结论婴儿纯母乳喂养比混合喂养及人工喂养具有明显的优越性,有利于促进婴儿的生长发育。
Objective To observe the effects of different feeding methods on the height and weight of infants. Methods 282 cases of infants born from March 2005 to March 2006 were enrolled in this study. They were divided into three groups according to the mode of feeding: 42 cases of breastfeeding group, 102 cases of mixed feeding group, 40 cases of artificial feeding group, Length, weight measurements. Results There was no significant difference in body weight and body length at birth between the three groups (P> 0.05). The body length and weight gain of the exclusive breastfeeding group at 42 days after birth were significantly higher than those of the mixed feeding group and the artificial feeding group (P <0.01). There was no significant difference in the growth of body length between the fed-fed group and the fed-fed group at 42d (P> 0.05), but the increased body weight increased compared with the fed-fed group (P <0.01). Conclusion Infant exclusive breastfeeding has obvious superiority over mixed feeding and artificial feeding, which is beneficial to promote infant growth and development.
