目的通过检测儿童血液中铁、锌、钙、铜、镁等微量元素的含量,了解其在儿童体内含量,探讨儿童微量元素缺乏的应对措施。方法随机抽取我院自2009年1月至2011年1月140例儿童,根据其年龄分为三个组:婴儿组39例、幼儿组48例和学龄前儿童组53例,采取各组儿童指血0.05ml,通过BH2100型原子吸收光谱仪进行检测微量元素的含量。结果各年龄阶段的儿童都存在不同程度的微量元素缺乏,婴儿组Fe缺乏率最高,与其他两组比较具有统计学意义(P<0.05);幼儿组Zn缺乏率最高,与其他两组比较具有统计学意义(P<0.05),学龄前儿童组Ca缺乏率最高,与其他两组比较具有统计学意义(P<0.05)。结论儿童普遍存在微量元素缺乏,针对各年龄阶段出现的相应微量元素缺乏,应该采取应对措施,合理膳食,提高营养,防止其影响生长发育。
Objective To detect the contents of trace elements such as iron, zinc, calcium, copper and magnesium in children’s blood and to find out the content of trace elements in children and explore the countermeasures for the lack of trace elements in children. Methods A total of 140 children in our hospital from January 2009 to January 2011 were randomly divided into three groups according to their age: 39 infants, 48 infants and 53 preschool children. Totally, Blood 0.05ml, by BH2100 atomic absorption spectrometry for the detection of trace elements. Results There were different degrees of micronutrient deficit in children of all ages, the highest rate of Fe deficiency in infants, which was statistically significant compared with the other two groups (P <0.05), the highest rate of Zn deficiency in infants was compared with the other two groups Statistical significance (P <0.05), Ca deficiency in preschool children group was the highest, compared with the other two groups was statistically significant (P <0.05). Conclusion There is a general lack of trace elements in children. In response to the lack of corresponding trace elements in all age groups, coping measures should be taken to rationally diet to improve nutrition and prevent it from affecting growth and development.
