摘　　要：目的：探讨不同孕期、不同年龄段孕妇母血微量元素钙、镁、锌、铁、铜含量水平的差异性,及其与孕期和年龄相关性。方法：检测10 131例孕早、中期孕妇血清的钙、镁、锌、铁、铜含量,早、中期妊娠分别按年龄分为3个阶段（≤25岁、25～35岁、≥35岁）进行分析。结果：（1）孕早、中期相比,铜水平较低,锌、镁、铁水平较高,差异均有统计学意义（P〈0.05）,钙水平比较差异无统计学意义（P〉0.05）。（2）孕早期不同年龄段5种微量元素比较,只有锌差异有统计学意义,25～35岁及≥35岁年龄段比≤25岁高（P〈0.05）,其余4种微量元素差异无统计学意义（P〉0.05）。（3）孕中期不同年龄段5种微量元素比较,锌和铁差异有统计学意义,25～35岁及≥35岁年龄段比≤25岁高（P〈0.05）,其余3种微量元素差异无统计学意义（P〉0.05）。结论 ：（1）孕早、中期孕妇体内微量元素镁、锌、铁、铜存在差异,钙没有明显差异;（2）不同年龄阶段孕妇体内微量元素存在差异;（3）根据孕妇不同孕期不同年龄阶段各种微量元素含量特点补充微量元素,满足母儿需求。Objective To investigate the levels of trace element in calcium, magnesium, zinc, iron and copper in maternal blood of pregnant women of different pregnancy and ages of pregnant women, and its relation to the pregnancy the age of pregnant women. Methods Calcium, magnesium, zinc, iron and copper in serum in 10 131 cases of pregnant women（3 565 cases in the first pregnancy, 6 566 cases in second pregnancy） were measured. All cases（both first pregnancy and second pregnancy） were analysed according to three age periods（less than or equal to 25, 25 to 35 years old, more than or equal to 35）. Results （1）Comparing to the cases in second pregnancy, Copper in serum of the cases in first pregnancy was lower, while zinc, magnesium and iron were higher（P〈0.05）. But the level of calcium had no difference（P〉0.05）.（2） For the cases in the first pregnancy in different age periods, all 5 kinds of trace elements were compared. Only the zinc level in serum in the groups of 25 ～ 35 years old and more than or equal to 35 years old was higher than that in the group of less than or equal to 25 years old（P〈0.05）. No difference was found in the rest of trace elements in different age groups（P〉0.05）.（3） For the cases in the first pregnancy in different age stages, all 5 kinds of trace elements were compared basis on the age periods. the zinc and iron levels in serum in the groups of 25 to35 years and more than or equal to 35 years old were higher than those in less than or equal to 25 years old（P〈0.05）. No difference（P〉0.05） was found in the other three kinds of trace elements in different age periods. Conclusions（1）There are differences in trace elements, magnesium, zinc, iron and copper, and no difference in calcium in the first and second pregnancy.（2）Trace elements in serum of pregnant women in different age periods are different.（3）According to the characteristics of various trace elements in serum of pregnant women of different pregnancy and age periods, trace
