目的观察儿童体内锌、铁、钙、铜、镁、铅这6种微量元素的含量并分析其影响因素,保障儿童健康成长。方法将我院2012年1月-2013年3月700例进行微量元素检测的儿童按照年龄分为4组:A组:<1岁;B组:1-3岁;C组:3-6岁;D组:>6岁。同时根据不同地区儿童分为E组(乡村儿童)、F组(城镇儿童)。分别采用微量元素检测仪及血铅分析仪对其进行检查并分析结果。结果不同年龄组间锌、铁、钙、铅含量差异显著(P<0.05),而铜、镁含量差异不显著(P>0.05);锌、铁含量随着年龄增长而增高,钙含量则逐渐降低。城镇儿童和乡村儿童微量元素缺乏差异较显著,乡村儿童微量元素缺乏率远高于城镇儿童。结论在儿童生长发育期易发生锌、铁、钙、铜、镁等微量元素缺乏,年龄越小越容易导致微量元素缺乏,而血铅含量则正好相反。
Objective To observe the contents of six trace elements such as zinc, iron, calcium, copper, magnesium and lead in children and analyze the influencing factors to ensure the healthy growth of children. Methods 700 children with microelement detection in our hospital from January 2012 to March 2013 were divided into 4 groups according to their age: Group A: <1 year old; Group B: 1-3 years old; Group C: 3-6 years old Group D:> 6 years old. At the same time, children in different regions are divided into group E (rural children) and group F (urban children). They were examined by trace element detector and blood lead analyzer and the results were analyzed. Results The contents of zinc, iron, calcium and lead in different age groups were significantly different (P <0.05), while the contents of copper and magnesium were not significantly different (P> 0.05). The content of Zn and Fe increased with age, reduce. The differences of trace elements in urban children and rural children are significant, and the lack of trace elements in rural children is much higher than that of urban children. Conclusion It is easy to occur the deficiency of trace elements such as zinc, iron, calcium, copper and magnesium during the growth and development of children. The younger the age, the easier to cause the lack of trace elements, while the blood lead content is the opposite.
