目的分析毒性元素与营养元素对学龄前儿童生长发育的影响。方法比较分析70例正常血元素儿童、51例高血铅儿童、60例高血钙儿童、55例高血铁儿童、61例高血锌儿童及58例高血铜学龄前儿童的身高、体质量和智商情况。结果正常组儿童智商明显高于高血铅组,差异有统计学意义(P<0.05);正常组儿童身高明显低于高血钙组,差异有统计学意义(P<0.05);正常组儿童身高明显高于高血铁组,差异有统计学意义(P<0.05);正常组儿童身高、智商均明显低于高血锌组,差异有统计学意义(P<0.05);正常组儿童身高明显低于高血铜组,差异有统计学意义(P<0.05)。结论钙、铁、锌、铜可影响学龄前儿童身高发育,铅、锌可影响智商发育,但上述元素对学龄前儿童体质量发育并无明显影响。
Objective To analyze the effects of toxic elements and nutrients on the growth and development of preschool children. Methods A total of 70 children with normal blood, 51 children with hyperlipidemia, 60 children with hypercalcemia, 55 children with hyperlipidemia, 61 children with hyperlipemia and 58 children with hypercholesterolemia were compared and analyzed. Quality and IQ situation. Results The IQ of children in normal group was significantly higher than that of high blood lead group (P <0.05). The height of children in normal group was significantly lower than that in hypercalcemia group (P <0.05) (P <0.05). The height and IQ of children in normal group were significantly lower than those in high blood zinc group (P <0.05), and the height and IQ of children in normal group were significantly higher than those in high blood zinc group Significantly lower than the high blood group, the difference was statistically significant (P <0.05). Conclusion Calcium, iron, zinc and copper can affect the height development of preschool children. Lead and zinc can affect the IQ development. However, these factors have no significant effect on body weight development of preschool children.
