孕妇微量元素铁随孕周变化的规律及其意义

目的:了解孕妇在不同孕期微量元素铁的变化规律。方法:按孕周将750名孕妇分为早孕(<12周)、中孕(12~28周)、晚孕(>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铁的含量,比较实验组及对照组微量元素值。结论:随着孕周的增加缺乏铁孕妇比例升高。孕早期应注意铁元素的补充。

Study on the changes regulation and significance of trace elements -iron for pregnant women

Objective:To explore the variety of trace elements- iron from pregnant women in different pregnant week.Methods:The 750 pregnant women were put into three groups by different pregnant week,(the early group:<12 w;the middle group:12-28 w;the lat 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 control group.Results:The percent of pregnant women lacking on iron went up notablely with the increased pregnant week.Conclusion:The pregnant women should be supplied with iron in their early pregnant period.
