目的了解门诊儿童及孕妇体内镁、锌、铜、铁、钙五种元素的含量,探讨其缺乏或过多的综合防治措施。方法使用原子吸收分光光度法对门诊体检的971例婴幼儿及孕妇末梢血做镁、锌、铜、铁、钙的检测。结果在婴幼儿3个年龄组中缺锌居第1位(44.7%),缺钙居第2位(28.5%);其次为缺铁,而且年龄越小这3种元素含量越低。孕妇中缺钙居第一位(38.5%),其次为缺锌(31.5%)。铜、镁这两种元素在4个年龄组中均比较接近正常水平。结论婴幼儿为生长发育最快时期,易缺乏铁、锌、钙元素,且年龄越小,越易缺乏。孕妇在怀孕期间也容易缺乏某些微量元素。提示各级政府、卫生部门应加大宣传力度,强调饮食合理,营养平衡,做到早期干预,早期治疗。
Objective To understand the contents of five elements of magnesium, zinc, copper, iron and calcium in outpatients and pregnant women, and to explore their lack of or excessive comprehensive prevention and treatment measures. Methods The atomic absorption spectrophotometry was used to detect the contents of magnesium, zinc, copper, iron and calcium in 971 infants and the peripheral blood of pregnant women. Results In infants and young children, the first zinc deficiency (44.7%) and the second calcium deficiency (28.5%) were the highest in the three age groups. The third was iron deficiency. The younger the age, the lower the three elements. Pregnant women in the first place calcium deficiency (38.5%), followed by zinc deficiency (31.5%). Copper and magnesium in the four age groups are closer to normal levels of these two elements. Conclusion The fastest growth and development of infants and young children, easy to lack of iron, zinc and calcium, and the younger, the more likely to lack. Pregnant women also lack certain trace elements easily during pregnancy. Prompted governments at all levels, the health sector should step up publicity efforts, emphasizing a reasonable diet, nutritional balance, so that early intervention, early treatment.
