孕妇微量元素分析

目的:了解孕妇在不同孕期微量元素的变化规律。方法:按孕周将624名孕妇分为早孕(小于16周)、中孕(16~28周)、晚孕(大于28周)3个实验组,126名正常体检妇女为对照组,采用原子吸收分光光度法检测孕妇及对照组妇女微量元素的含量,比较实验组及对照组微量元素值。结果:随着孕周的增加,缺乏铁和镁的孕妇比例升高,钙元素早孕组缺乏的比例最高,中孕组孕妇缺锌比例最高。结论:孕妇早孕期应注意钙元素的补充,中孕期应加强锌、镁、铁元素的补充。

Analysis the Trace Elements of Pregnant Woman

Objective:To explore the variety of trace elements from pregnant woman in different pregnant week.Methods:The 750 pregnant women were put into three groups by different pregnant week(the early group:<16 w;the middle group:16～28 w;the late group:>28 w= compared with 126 non-pregnant women.The contents of trace elements of these women were determined by atomic absorption spectrophotometry, and the results were analyzed by comparing the values of experimental groups and the group.Results:The percent of pregnant women lacking on iron,zinc and magnesium went up notable with the increased pregnant week;The percentage of the cal-deficiency is largest in the early group and the zinc-deficiency is largest in the middle group.Conclusion:The pregnant women should be supplied with calcium in their early pregnant period,and supplied with zinc,magnesium and iron from middle pregnancy.
