摘要
目的 :了解少年儿童营养状况及目前发中锌、铁、钙含量 ,选择客观、科学地补充微 (常 )量元素的技术和方法。方法 :用极谱分析法的模拟单扫描方式 (LSP法 )对发样进行Zn、Fe、Ca含量测定 ,并对有关数据进行统计分析。结果 :在 2 18例有一定临床症状、体征的亚健康状态的研究对象中 ,Ca含量明显偏低者最多 94例( 4 3 12 % ) ,多出现夜间哭闹、盗汗、鸡胸、出牙迟、磨牙等 ;其次为Fe含量明显偏低者 89例 ( 4 0 83% ) ,多出现贫血、偏食、厌食、营养不良等 ;Zn含量明显偏低者最少 35例 ( 16 0 6 % ) ,多出现体质弱、发育差、异嗜、精力不集中等 ;受检者发样中Zn、Fe、Ca的含量均为 0～ 2岁组较高 ,3～ 5岁组最低 ,6～ 15岁组随年龄增长逐年明显升高。结论 :当前少年儿童普遍缺乏微量元素 ,应科学地补充微 (常 )量元素 ,提高营养水平。
Objective: Observe the status of malnutrition among teenage and children and to exam the concentration of zinc, iron and calcium in the hair, then develop a new technique for the trace elements complement objectively and scientifically. Methods : Mensurate the concentration of zinc, iron and calcium in hair samples using LSP, then run a statistic analyze on relevant data. Results: Of all 218 cases under the condition of sub-health who have clinical symptoms , 94 cases(43 12%) whose calcium concentration is lower than that of others significantly appear clinical symptoms of crying at night, night sweat, pectus carinatum, tooth growth late, grinding teeth; 89 cases(40 83%) whose iron concentration is lower appear clinical symptoms of malnutrition, anemia, partial food predilection and anorexia;some cases whose zinc concentration is lower appear weakness, heteroplasia,disconcentration and strange addiction. Of the concentration of zinc, iron and calcium in all cases' hair, the group aged from infant to two is highest; the group aged from three to five is lowest and the group aged from six to fifteen is increased gradually. Conclusion: The trace elements are lack generally among teenage and children at present, so these elements should be complemented properly for them.
