微量元素与妊娠不良结局的原因分析及饮食护理

Trace Elements and the Adverse Pregnancy Outcome: Cause Analysis and Diet Nursing

目的分析孕妇体内主要微量元素的变化情况,为预防妊娠不良结局和合理指导妊娠期微量元素的饮食提供参考。方法采用原子吸收分光光度法分析我院2009年6月到2012年9月共178例的不同妊娠时期孕妇体内锌、钙、铁、铜、硒的情况。结果随着孕周的增加,孕妇体内锌、钙、铁、硒的含量水平不断降低,而铜的含量水平稍有升高。结论微量元素的变化可影响妊娠结局,根据孕妇体内微量元素含量水平的变化,合理指导补充不同的微量元素饮食,有利于妊娠结局。

Objective To analyze the changes of major trace elements in the pregnant women, to prevent adverse outcomes of pregnancy and reasonably guide the trace elements of diet during pregnancy for a reference. Methods Atomic absorption spectrophotometry was used to detect the calcium, iron, zinc, copper, selenium in the body of 178 pregnant women at different pregnant stages. Results With the increase of gestational weeks, the contents of calcium, iron, zinc and selenium decreased, but the copper level increased slightly. Conclusions Pregnancy outcome can be affected by changes of trace elements. According to the changes in the levels of trace elements in pregnant women, reasonable guidance of supplementary trace elements by different diets is beneficial to pregnancy outcomes.
