摘　　要：目的了解孕妇及其新生儿血液中微量元素的相关性。方法采用原子吸收光谱法对136例产妇及其新生儿血液中铜(Cu)、锌(Zn)、钙(Ca)、镁(Mg)、铁(Fe)5种微量元素进行测定,并做统计学分析。结果孕妇低钙、低铁者占较大比例,分别为44.44%和94.44%,新生儿低钙、低铁者占较大比例,分别为47.22%及22.20%,母婴间微量元素均值比较差异有统计学意义;相关性比较Cu和Mg相关系数(r)为0.3～0.7,呈中度相关;而Ca、Zn、Fer<0.3,无相关性。结论孕妇和新生儿应当定期检测血微量元素并适当补充,特别是孕晚期钙、铁的补充及新生儿钙的补充。胎盘对微量元素具有很强的主动转运功能。Objective To investigate the correlation of trace elements in pregnant women and their neonates. Methods Atomic absorption spectrographic method was employed to measure blood trace elements [including copper （Cu）, zinc （Zn）, calcium （Ca）, magnesium （Mg）, ferrum （Fe）] in 136 pregnant women and their neonates. Then the statistical analysis was performed. Results The pregnant women with low calcium and with low ferrum accounted for 44.44% and 94. 44% respectively; as their neonates were concerned, the percentage with low calcium and with low ferrum was 47.22% and 22.20% respectively. There were significant significance between the pregnant women and their neonates in mean value of each of trace elements. Correlative analysis indicated that the correlation coefficient of Cu and Mg was 0.3-0.7, displaying medium correlative; while the correlation coefficient of Ca, Zn and Fe was lower than 0.3, displaying not correlative. Conclusion Pregnant women and their neonates should receive trace element.measurement periodically and appropriately supply possible scanty trace elements, especially for the supplement of calcium and ferrum in the late trimester of pregnancy. The placenta has very strong active transport function.
