目的了解兰州市红古区学龄前儿童体内微量元素水平,为学龄前儿童的合理饮食提供指导。方法随机抽取兰州市妇幼保健所体检的0~7岁学龄前儿童1 000例,应用SK-Ⅱ型微量元素分析仪进行血液中钙、锌、铁、铜微量元素检测并做统计分析。结果兰州市学龄前儿童均存在不同程度的微量元素钙、铁、锌和铜缺乏的情况,且除元素铜外各年龄段的差异均具有统计学意义(P<0.05),但性别之间的差异除元素钙外均不具有统计学意义(P>0.05)结论兰州市红古区学龄前儿童微量元素缺乏和过高情况不容乐观,必须注意各种营养素的合理搭配及微量元素的补充。
Objective To understand the levels of trace elements in preschool children in Honggu District of Lanzhou City and provide guidance for the reasonable diet of preschool children. Methods A total of 1 000 pre-school children aged 0-7 years were collected from Lanzhou MCH hospital. Trace elements (calcium, zinc, iron and copper) in the blood were detected by SK-Ⅱ microelement analyzer and analyzed statistically. Results There were different levels of trace elements calcium, iron, zinc and copper in Lanzhou preschool children, and the difference was statistically significant (P <0.05) The differences were not statistically significant except elemental calcium (P> 0.05) .Conclusion The lack of trace elements and excessive condition of preschool children in Honggu district of Lanzhou City should not be optimistic. We must pay attention to the rational collocation of various nutrients and the supplement of trace elements.
