门诊儿童1438例微量元素检测结果分析

目的了解散居儿童末梢血中铜、锌、钙、镁、铁5种元素含量及缺乏情况,为散居儿童合理营养指导提供依据。方法选择儿保门诊入园体检儿童及定期体检儿童1438例作为调查样本,采末梢血用原子吸收光谱法检测血中5种微量元素的含量。结果 7岁以下不同性别儿童末梢血中5种微量元素含量差别不大,3岁以下儿童铁、锌两种元素含量随年龄而增高,而钙含量随年龄而降低,铁、锌缺乏在0～1岁最高分别为18.10%和57.14%,钙缺乏在3～4岁最高为18.44%。结论年龄不同,微量元素含量不同,微量元素缺乏的情况不同。建议在不同年龄阶段,儿童保健医生适时给予合理营养指导,减少微量元素的缺乏,促进儿童体格发育。
