龙津街婴儿辅食添加与微量元素含量的关系

Relation between Supplementary Food Additions of for Infants in Longjin Street and Trace Elements Content

为了解荔湾区龙津街婴儿辅食添加时间及结构对其体内微量元素含量有无影响 ,减少微量元素失衡对婴儿生长发育的影响 ,采用分层抽样方法对龙津街内进行“4-2 -1”体检的 3 98名3～ 1 2个月散居婴儿进行辅食添加情况了解 ,同时检测其头发中碘、锌、铁、钙、铜、锰的含量。用 χ2 求得两者关系P <0 0 1、P <0 0 5 ,表明辅食添加的时间正常与否、添加辅食结构是否合理对其头发中微量元素含量有密切关系。科学地进行辅食添加对平衡婴儿体内微量元素含量 ,促进其健康生长有重要意义。

In order to identify the in fluence of the time and structure of supplementary food addition on trace elements of infants growth in Liwan district,the application of supplementary food additions to 398 infants at the age of 3 months to 12 months randomly,who have the `4-2-1'body examination in Longjin street was studied by the graditional sampling method.Meanwhile,the content of iodine ,zinc,iron,calcium,copper and manganese contained in the infants'hair was determined and the formular χ 2 was used to draw a conclusion that the relation between them in P <0 01, P <0 05 It indicates that wether the time of supplementary food addition is normalized and the structure is rational has intimate connection with the trace elements content contained in the infants'hair.It is important that add supplementary food scintifically to balance the trace elements in infants and improve their healthy growth.
