目的:了解西宁地区婴幼儿体内微量元素的含量水平。方法:采用BH5100plus五通道原子吸收光谱仪,对我院门诊390例健康体检婴幼儿末梢指血微量元素(Cu、Zn、Ca、Mg、Fe)值进行检测。结果:男女间婴幼儿指血5种微量元素水平比较差别均无显著性P>0.05,5个年龄段的血5种微量元素含量之间比较铜、钙、镁、铁均无差别P>0.05。锌元素水平有较大的年龄阶梯,呈递增趋势,其中3岁~<4岁段和≥4岁段与其他三组锌元素含量比较差别有显著性(P<0.01)。结论:根据地区环境及生活习惯合理摄取营养,科学补充微量元素,建议应把微量元素检查列为常规项目,以便了解婴幼儿营养状况,为指导矫正提供参考依据。
Objective: To understand the content of trace elements in infants and young children in Xining area. Methods: The trace elements of blood (Cu, Zn, Ca, Mg, Fe) in the peripheral blood of 390 infants and young children in our hospital were detected by BH5100plus five-channel atomic absorption spectrometer. Results: There was no significant difference in the levels of 5 trace elements in blood between boys and girls, P> 0.05. There was no significant difference in the content of 5 trace elements in blood between 5 and 5 age groups . The level of zinc had a larger age ladder, showing an increasing trend. The content of zinc in the 3-year-old to 4-year-old group and the 4-year-old group was significantly different from the other three groups (P <0.01). Conclusion: According to the regional environment and living habits, it is reasonable to take nutrition and supplement the trace elements scientifically. It is suggested that the trace element examination should be listed as a regular item in order to understand the nutritional status of infants and toddlers and provide reference for guiding the correction.
