目的:了解孕妇在不同孕期微量元素的变化规律,及时合理为孕妇补充微量元素提供依据。方法:将750名孕妇按周期分为早孕(<16周)、中孕(16～28周)、晚孕(>28周)三个实验组,252名未孕体检妇女为对照组,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钙、铁的值。结果:随着孕周的增加缺乏铁的孕妇比例升高,钙元素早孕组缺乏的比例最高。结论:孕妇应定期检测,在医生的指导下早期应注意钙元素的补充,中孕期应加强铁元素的补充。
Objective: To understand the changes of trace elements in different pregnant women in pregnant women in a timely and reasonable manner to provide trace elements for pregnant women. Methods: 750 pregnant women were divided into three groups: pregnancy (<16 weeks), middle pregnancy (16-28 weeks), late pregnancy (> 28 weeks), 252 pregnant women without pregnancy as control group, The contents of trace elements in pregnant women and control group were detected by absorption spectrophotometry, and the contents of trace elements calcium and iron in experimental group and control group were compared. Results: With the increase of gestational age, the proportion of pregnant women who lack iron increased, and the proportion of calcium deficiency in early pregnancy group was the highest. Conclusion: Pregnant women should be regularly tested, under the guidance of a doctor should pay attention to the early calcium supplement, iron supplement should be strengthened in the second trimester.
