目的了解宝鸡地区儿童体内5种元素(铜、锌、钙、镁、铁)含量的现状,为制定预防措施提供依据。方法选择630名健康体检的儿童(4月~14岁),按年龄分成婴儿、幼儿、学龄前、学龄期4组,采集静脉血,使用BH5100型多通道原子吸收光谱仪检测全血中铜、锌、钙、镁、铁的含量,并对数据进行t检验和方差分析。结果 630例儿童不同性别全血5种元素(铜,锌,钙,镁,铁)水平间差异无统计学意义(P>0.05),不同年龄组铜、锌、钙、铁水平比较差异有统计学意义(P<0.05);而不同年龄组镁水平比较差异无统计学意义(P>0.05)。630例儿童中缺锌268例(42.5%)、缺铜126例(20.0%)、缺铁114例(18.1%)、缺钙84例(13.3%)、缺镁6例(1%)。结论儿童处于生长发育期,易缺乏铁、锌、铜等元素,尤其是缺锌,易被家长忽视。应加大宣传及防治力度,强调饮食合理,营养平衡。
Objective To understand the current status of five elements (copper, zinc, calcium, magnesium and iron) in children in Baoji area, and provide the basis for making preventive measures. Methods 630 healthy children (April to 14 years old) were selected and divided into 4 groups according to age, including infants, toddlers, preschool children and school-age children. Venous blood was collected and analyzed by BH5100 multi-channel atomic absorption spectrometry , Calcium, magnesium, iron content, and t-test data and analysis of variance. Results There was no significant difference in the levels of five elements (Cu, Zn, Ca, Mg, Fe) among 630 children with different genders of whole blood (P> 0.05). The differences of Cu, Zn, Ca and Fe in different age groups were statistically significant (P <0.05). There was no significant difference in magnesium levels between different age groups (P> 0.05). Of the 630 children, 268 were zinc deficiency (42.5%), 126 were copper deficiency (20.0%), 114 were iron deficiency (18.1%), 84 were calcium deficiency (13.3%) and 6 were magnesium deficiency (1%). Conclusion Children are in the growth and development period, easy to lack of iron, zinc, copper and other elements, especially zinc deficiency, easily overlooked by parents. Should increase publicity and prevention efforts, emphasizing a reasonable diet, nutritional balance.
