目的:调查了解西北地区妊娠妇女全血铜、锌、钙、铁、镁等微量元素水平,为其合理补充微量元素提供临床依据。方法:选择来我院产检妊娠妇女300例为观察组,另选正常育龄非妊娠妇女102例为对照组。采用原子吸收法测定并比较两组铜、锌、钙、铁、镁等微量元素水平。结果:妊娠妇女微量元素缺乏居前3位的是钙38例(12.7%),锌27例(9.0%),铁15例(5.0%);而铜、镁缺乏较少。观察组铜水平非常显著高于对照组(P<0.01),锌、钙水平显著低于对照组(P<0.05),铁、镁水平两组差异不显著(P>0.05)。结论:妊娠妇女应根据微量元素检查结果合理补充微量元素。
Objective: To investigate the level of trace elements copper, zinc, calcium, iron and magnesium in whole blood of pregnant women in Northwest China and to provide the clinical basis for the rational supplementation of trace elements. Methods: 300 pregnant women of our hospital were selected as the observation group. Another 102 non-pregnant women of normal childbearing age were selected as the control group. The levels of trace elements such as copper, zinc, calcium, iron and magnesium in the two groups were determined and compared by atomic absorption spectrometry. Results: In the third trimester of pregnant women with trace elements deficiency, there were 38 cases of calcium (12.7%), 27 cases of zinc (9.0%) and 15 cases of iron (5.0%), while the deficiency of copper and magnesium was less. The levels of copper and copper in the observation group were significantly higher than those in the control group (P <0.01). The levels of zinc and calcium in the observation group were significantly lower than those in the control group (P <0.05). Conclusion: Pregnant women should be based on the trace element test results reasonable trace elements.
