广西贺州市孕妇全血微量元素检测结果探讨

ANALYSIS OF BLOOD TRACE ELEMENTS OF PREGNANT WOMEN IN HEZHOU

目的:探索广西贺州市孕妇和健康妇女全血微量元素含量水平,为合理补充微量元素提供参考依据。方法:将968例来自广西贺州市人民医院孕妇按孕周分为早孕组186例,中孕组730例和晚孕组52例,采用原子吸收分光光度法检测早孕组、中孕组、晚孕组及86例来自广西贺州市人民医院正常对照组妇女全血中的微量元素铜、锌、钙、镁、铁的含量,比较4组检测值。结果:早、中、晚孕组与对照组相比,铜随孕期增加而增加,差异有统计学意义(P<0.01),但早、中、晚孕3组间差异无统计学意义(P>0.05);全血锌、钙在早、中孕期随孕周的增加其含量不断降低,与对照组比较,差异有统计学意义(P<0.05),但早、中、晚孕3组比较无明显差异(P>0.05);全血镁、铁随孕周的增加其含量不断降低,早、中、晚孕期检测结果与对照组比较均有差异(P<0.05);其中铁元素早、中、晚孕组均缺乏明显(P<0.01)。结论:广西贺州市孕妇应该根据自身情况适当补充微量元素。

Objective.To compare the levels of serum trace elements between pregnancy women and healthy women in Hezhou, and provide the reference for the replenishment of trace elements. Methods： A total of 968 cases of pregnancy women were divided into three groups according to pregnancy weeks, early pregnan- cy （〈16 weeks, n =186）, middle pregnancy （16 to 28 weeks, n =730）, and late pregnancy （〉28 weeks, n =52）. Serum trace elements in three groups and a normal group （ n =86） were detected by atomic ab- sorption spectrophotometry. Results. As compared with control group, serum copper in group pregnancy increased significantly with the time of pregnancy （ P 〈0.01）, while serum magnesium and iron reduced significantly （ P 〈0.05）. Serum zinc and calcium in groups early pregnancy and middle pregnancy reduced significantly with the time of pregnancy （ P 〈0.05）. Serum iron in groups middle pregnancy and late preg- nancy reduced significantly than those in group early pregnancy with the time of pregnancy （ P 〈0.05）. Conclusion： Pregnancy women should be supplied with trace elements.
