目的:了解不同孕期孕妇微量与常量元素缺乏情况,为其合理补充提供依据。方法:按孕周将孕妇分为3个组,正常育龄非孕妇女为对照组;采用原子吸收光谱法检测孕妇及对照组妇女血清微量元素含量。结果:3776例妊娠妇女主要以缺钙、铁为主,各组间差异显著(P<0.01),与对照组比较差异显著(x2=348.46,x2=182.96,P<0.01);锌在中孕组缺乏比例增高,晚孕组缺乏明显,铜、镁元素缺乏比例与对照组比较无差异(P>0.05)。结论:应加强孕妇微量与常量元素的监测,了解其缺乏情况及时补充缺乏的微量与常量元素,做好孕期保健工作。
OBJECTIVE: To understand the lack of trace elements and macronutrients in different pregnant women and provide the basis for their rational supplementation. Methods: Pregnant women were divided into 3 groups according to gestational age, and normal non-pregnant women of childbearing age served as control group. The contents of serum trace elements in pregnant women and control group were detected by atomic absorption spectrometry. Results: 3776 pregnant women were mainly calcium-deficient and iron-dominated, with significant difference between the groups (P <0.01), with significant difference compared with the control group (x2 = 348.46, x2 = 182.96, P <0.01) Lack of proportion of the group increased, lack of obvious late pregnancy group, the ratio of copper and magnesium deficiency compared with the control group no difference (P> 0.05). Conclusion: We should strengthen the monitoring of trace elements and macronutrients in pregnant women, understand the lack of them, and replenish the lack of trace elements and macronutrients in time to do the health care during pregnancy.
