矮身材儿童血铅镉锌钙铁铜镁水平分析

目的探讨血铅、镉、锌、钙、铁、铜、镁水平对儿童生长发育的影响。方法通过采用钨舟原子吸收光谱仪测定我院儿保门诊53例矮身材儿童（矮身材组）及53例正常儿童（对照组）末梢静脉血中铅、镉、锌、钙、铁、铜、镁水平，并对其与儿童生长发育关系进行分析。结果矮身材儿童血铅明显高于正常对照组，锌、钙、铁明显低于正常对照组（P〈0．05）。而血镉、铜、镁与对照组则无明显差异。矮身材组血铅男童明显高于女童（P〈0．05）。结论矮身材儿童的生长发育迟缓可能与高血铅，低血锌、钙、铁密切相关。儿童铅中毒防治和合理的膳食结构是降低儿童矮身材发生率的重要措施。

Analysis on serum lead, cadmium, zinc, caicium, iron, copper, magnesium level of microsomia children

Objective To assess the effect of serum lead, cadmium, zinc, calcium, iron, copper,magnesium level on children's growth and development. Methods Use Wu Zhou atomic absorption spectrometer to detect the periphery vein serum of lead, cadmium, zinc, calcium, iron, copper, magnesium level in fifty three microsemia children (microsomia children group) and fifty three normal height children (control group), and analysis the relation to the children's growth. Results The serum lead of the microsomia children group was significant higher than the control group. The serum zinc, calcium and iron were signif-icant lower in the mierosomia children group than the control group, all(P<0.05). While the serum copper and cadmium and magnesium were not significant different comparing with the control group. In the microsemia children group between the male and feinale children, except that the serum lead was significant higher in, the male children than the female, while the others were not significant different. Conclusion As the serum level of high lead, and low fine, calcium, iron and magnesium may affect the growth and development of mierosomia children, we should adjust dietary pattern of microsemia children and prevent and cure lead poisoning of chidren.
