辅助喂养指导对新城市人口婴儿营养水平的影响

Influence of assistant feeding guidance on nutrition level of infants

目的：探讨如何提高新城市人口中新生代农民工、外来务工人员所生婴儿的营养水平。方法随机抽取2010年7月至2012年7月年龄别体重在-2SD以下的2～10月龄的婴儿500例（其父母均为新生代农民工、外来务工人员），随访调查喂养状况，针对喂养存在的问题进行干预，定期监测及评估，并对喂养状况及干预前后血清指标检测结果做统计学分析。结果被抽样调查的500例婴儿干预前血清前白蛋白（135．11±19．42） mg/L，血锌（3．24±0．59） mg/L，血清铁（8．38±4．17）μmol/L，通过干预措施，血清前白蛋白达到（214．22±38．20）mg/L（t＝2．23，P＜0．05），血锌（3．97±0．72）mg/L（t＝2．79，P＜0．05），血清铁（12．20±5．10）μmol/L（t＝1．64，P＜0．05），说明干预前后血清前白蛋白、血锌、血清铁指标变化具有统计学意义。结论提高新城市人口婴儿营养水平要从培养家长对婴儿期喂养形成良好的进食行为开始，对不同的家庭状况给予不同的指导，取得家长们很好的配合，从而达到良好效果。

Objective To explore how to improve the nutrition level of infants as the new generation of peasants and migrant workers in city.Methods Totally 500 2-10 months old infants below -2SD were randomly selected from July 2010 to July 2012 （ their parents were the new generation of peasants and migrant workers ） , and their feeding was investigated .Intervention for feeding problems , regular monitoring and evaluation were conducted .The feeding status and serum indexes before and after intervention test were statistically analyzed.Results Infants’ serum prealbumin was 135.11 ±19.42mg/L, serum zinc was 3.24 ±0.59mg/L, and serum iron was 8.38 ± 4.17μmol/L, respectively, before intervention.After the intervention they were 214.22 ±38.20 mg/L, 3.97 ±0.72 mg/L and 12.20 ± 5.10μmol/L, respectively （t value was 2.23, 2.79 and 1.64, respectively, all P＆lt;0.05）.The changes in serum albumin, serum zinc, serum iron indices were statistically significant .Conclusion Improvement of nutrition level of infants of new population in city should start from fostering parents ’ good feeding behavior .Different guidance for different family and gaining parents ’ cooperation will achieve good effect.
