三亚地区0～6岁儿童外周指血钙、铁、锌检测的临床意义

Clinical significances of calcium,iron,and zinc detection in finger blood of 0-6-year-old children in Sanya area

目的:了解三亚地区0～6岁不同年龄段儿童外周指血钙、铁、锌的变化。方法:将2009年10月～2010年3月健康体检的5 000名儿童,按年龄段分成7组,体检儿童由经培训的检验师用定量毛细血管取无名指末梢血0.04 ml,检测钙、铁、锌水平。结果:铁、锌浓度在2岁内均较低,尤其是6个月以内,随年龄的增长存在增加的趋势,铁锌各组间差异有统计学意义(P<0.01),但各组间钙含量变化不大(P>0.05)。结论:三亚地区学龄前儿童,强调生后半月补充维生素D,多晒太阳,不要盲目大量、过早补钙。4～5月后应从膳食中补充富含铁、锌的食物,如肝泥、蛋黄、婴儿配方食品等。做到科学补给,避免过度。

Objective： To understand the changes of calcium, iron, and zinc contents in finger blood of 0 - 6 - year - old children in Sanya area. Methods： A total of 5 000 children who received physical examination from October 2009 to March 2010 were divided into seven groups according to age, 0. 04 ml ring finger blood samples of the children were obtained by laboratorians after training with quantitative capillaries to detect the levels of calcium, iron, and zinc. Results： The contents of iron and zinc in children under two years old was relative- ly low, especially in the children under six months, showing an increasing trend with age; there was statistically significant difference in the levels of iron and zinc among the children at different age groups （P 〈 O. Ol ） , but there was no statistically significant difference in the level of calcium among the children at different age groups （ P 〉 0. 05 ） . Conclusion ： For the preschool children in Sanya area, it is emphasized to supply vitamin D and sun within 15 days after birth, calcium should not be supplied blindly, largely, and too early. The foods containing iron and zinc should be supplied to the children after 4 - 5 months, such as liver paste, yolk, and infant formula. Scientific replenishment should be performed, and too excessive replenishment should be avoided.
