【摘要】 目的 :探讨本地区学龄前儿童 Zn、Fe、Ca营养状况。方法 :采用原子吸收分光光度法对本地区 497例学龄前儿童头发中 Zn、Fe、Ca含量进行检测。结果 :本地区学龄前儿童发中 Zn、Fe、Ca含量分别为 1 1 4± 7.7,44.9± 4.3 ,447.2± 5 0 .8μg/g。不同年龄段、不同性别之间发Zn、Fe、Ca含量无显著差别 ;Zn、Fe、Ca缺乏率分别为 3 1 .6%、1 0 .7%、2 5 .4% ;随年龄增长 ,Fe、Ca缺乏率逐渐增高 ,差别有显著意义。结论 :本地区小儿 Zn、Fe、Ca营养状况仍处于一个较低水平 ,各年龄组这些元素的营养不良状况不尽相同 ,预防 Zn、Fe、Ca营养不足 ,仍是目前小儿时期最主要的健康问题更多还原

【Abstract】 Objective To investigate the nutritional status of Zn,Fe,Ca among preschool children in Puchen district.Methods:Using atom absorption spectrophotometry.in the measurements of hair Zn,Fe,Ca concentration,We studied a total of 497 healthy preschool children in Puchen district.Results:Of the 497 subjects,the hair zinc,iron and calcium content was114.2±7.7 μg/g,44.9±4.3 μg/g,447.2±50.8 μg/g,respectively.The hair Zn,Fe,Ca content did not relate to age and gender.The prevalence of Zn,Fe,Ca deficiency was 31.6%,10.7%,25.4%,respectively.The prevalence of Fe,Ca deficiency increased with age and the difference is significant in statistics.Conclusions,The zinc,iron,calcium nutritional status among preschool children in Puchen district was still in a lower lever,the prevalences of zinc,iron,calcium deficiency among different age groups were variant.The prevention of zinc,iron calcium deficiency is still one of the most crucial healthy tasks in childhood today.更多还原
