目的了解本地区孕妇的微量元素水平变化,为孕期保健及优生优育提供参考数据。方法将324名孕妇按孕周分为早孕(<12周)、中孕(12-28周)和晚孕(>28周)3组,120名正常妇女为对照组,采用原子吸收光谱法测定各组样本的铅(Pb)、镉(Cd)、铜(Cu)、锌(Zn)、钙(Ca)、镁(Mg)、铁(Fe)共7种元素,并对其结果进行对比分析。结果孕妇组的Zn、Ca含量明显低于对照组,有显著性差异(P<0.05);晚孕组的Pb含量明显高于其它3组,有显著性差异(P<0.05)。结论女性妊娠期应定期进行微量元素的监测,根据不同孕周及时进行调整。
Objective To understand the changes of trace elements in pregnant women in this area and provide reference data for health care and prenatal and postnatal care during pregnancy. Methods 324 pregnant women were divided into three groups according to gestational age: first trimester (<12 weeks), second trimester (12-28 weeks) and second trimester (> 28 weeks), and 120 normal women as control group. The contents of Pb, Cd, Cu, Zn, Ca, Mg and Fe in each group were compared and the results were compared . Results The levels of Zn and Ca in pregnant women were significantly lower than those in the control group (P <0.05). The levels of Pb in pregnant women were significantly higher than those in the other three groups (P <0.05). Conclusion The monitoring of trace elements in women during pregnancy should be carried out regularly and adjusted according to different gestational weeks.
