目的了解本地区婴儿生长发育状况，母乳与人工喂养对生长发育的影响，探讨生长发育的“标准”适用性。方法以体重、身高、头围、胸围等指标，两组比较，以t检验进行统计分析。结果监测对象初生时体重、身高与全国现执行标准基本一致，经统计差异无显著性（P＞0．05），头围、胸围在3月、6月时亦基本一致；但监测对象男、女婴儿身高、体重差异明显（P＜0．05-0．001）；不同喂养方式监测表明，母乳喂养组男、女婴儿3个月体重均高于人工喂养组（P＜0．05），女婴身高6个月时高于人工喂养组（P＞0.05）。结论全国现行儿童生长发育标准适用于遵义。遵义目前以全国男童标准统一作为男女儿童生育发育标准不太适宜，母乳喂养对儿童生长发育有较大益处。
Objective To understand the status of infant growth and development in this area, the effects of breast-feeding and artificial feeding on the growth and development, and to explore the “standard” applicability of growth and development. Methods Weight, height, head circumference, chest circumference and other indicators, the two groups were compared by t test for statistical analysis. Results The body weight and height of the monitoring subjects at birth were basically the same as those in the whole country. There was no significant difference (P> 0.05) between the body weight and height of the monitoring subjects. The head circumference and the chest circumference were basically the same in March and June. However, The height and weight of female infants were significantly different (P <0.05-0.001). The monitoring of different feeding methods showed that the body weights of male and female infants in breastfeeding group were higher than those in artificial feeding group (P <0.05) The height of baby girl was higher than that of artificial feeding group at 6 months (P> 0.05). Conclusion The current national children’s growth and development standards apply to Zunyi. Zunyi now the national standard of boys as a standard reproductive development of boys and girls is not appropriate, breast-feeding on child growth and development have greater benefits.
