摘要
目的 :了解深圳南山 3岁以下儿童血微量元素状况及其对健康的影响。方法 :用原子吸收分光光度计 ,火焰原子吸收法检测血微量元素Cu、Fe、Zn、Ca、Mg、P ,日本东亚SF - 30 0 0五分类血球仪 (SDS法 )测定Hb ,Z评分法、NCHS标准评价儿童生长发育。结果 :2 35名 3岁以下儿童血微量元素除Cu、Mg全部在正常范围外 ,Ca、Zn、Fe、P均有不同程度缺乏 ,儿童缺Ca 71 0 6 % ,缺Zn 5 4 89% ,缺P 2 2 12 % ,缺Fe 6 8%。Zn与Hb正相关 ,Mg与Hb负相关 ,贫血儿童血铁、锌值低 ,而血钙、镁值高于非贫血儿童。生长迟缓儿童血钙 2 .2 7μmol/L ,明显低于正常儿童血钙值。结论 :南山区 3岁以下儿童微量元素缺乏相当严重 ,尤以钙、锌缺乏为甚 。
Objective: To explore trace element situation of children under 3 years of age in Shenzhen Nanshan district and the relationship between trace element and nutrition status. Methods: the contents of serum cuprum(Cu)、Iron(Fe)、zinc(Zn)、calcium(Ca)、Magnesium(Mg)、phosphorus(P) were detected with atomic absorption technique. The concentration of hemoglobin(Hb) was measured by SDS. Children heath situation were assessed by using NCHS standards. Results: 235 children under 3 years of age had a marked deficiency of most mineral materials expect Cu and Mg, the incidence of Ca deficiency、Zn deficiency、P deficiency、Iron deficiency were 71 06%、54 8%、22 12%、6 8%, respectively. There was a negative correlation between Hb concentration and serum Mg level. while a positive correlation between Hb concentration and serum Zn level. In children with anemia, the levels of serum Fe、Zn were decreased while the levels of Cu、Mg were increased as compared with those in normal children. We also observed that serum Ca was significantly low in stunted. Conclusion: there was a marked deficiency of mineral materials in children under 3 years of age, especially in Ca、Zn. It is important for children to improve nutritive status through mineral element supplementation.
