摘要
目的通过分析杭州地区不同年龄段不同孕期孕妇全血中微量元素水平变化情况,为孕妇合理补充微量元素提供临床指导。方法分别按孕周和孕龄将孕妇分组,以健康非妊娠妇女作为对照组,采用原子吸收光谱法测定全血中锌、铜、铁、钙、镁5种微量元素含量。结果孕妇整个孕期全血中5种微量元素与对照组相比,铁和镁含量明显低于对照组,差异有统计学意义（P〈0.01）;铜和钙含量明显高于对照组,差异有统计学意义（P〈0.01）,而锌含量差异无统计学意义（P〉0.05）。按怀孕年龄分组后,发现不同年龄妇女妊娠期内均易缺乏铁和钙,缺铁率为16.13%~19.52%,缺钙率为23.14%~30.45%,而随着年龄的增加钙缺乏越来越严重,31岁~45岁孕妇组中钙缺乏率最高。结论杭州地区不同年龄段不同孕期孕妇体内微量元素含量存在一定差异,提示妊娠期妇女应定期进行微量元素检测,并根据自身孕龄合理补充微量元素,以保证母体和胎儿双方需求,提高优生优育几率。
Objective To analyze the different levels and changes of trace elements in the whole blood of pregnant women in Hangzhou at different ages and various gestation periods,so as to provide clinical guidance on supplementing trace elements for pregnant women. Methods According to gestational age and gestation periods,pregnant women were respectively divided into different groups. Meanwhile,non- pregnant healthy women were selected as a control group for comparison. Atomic absorption spectrophotometry（ AAS） was applied to the determination of the contents of zinc,copper,iron,calcium and magnesium in the whole blood. Results There was statistical significance on the differences in the contents of five trace elements in whole blood between pregnant women and the control group,with the levels of iron and magnesium in pregnant women were significantly lower than that of the control group（ P〈0. 01）; and the levels of copper and calcium in pregnant women were significantly higher than that of the control group,with the differences statistically significant（ P〈0. 01）. While,there was no statistical significance on the difference of zinc（ P〈0. 05）. According to the results from pregnant women at different ages,it is showed that different age groups of pregnant women were all prone to lack of iron and calcium,and the iron- deficiency ratio was within16. 13%- 19. 52%,and the calcium- deficiency ratio was within 23. 14%- 30. 45%. With the increasing of gestational age,the calcium deficiency becomes increasingly serious,and the calcium- deficiency ratio of pregnant women aged 31- 45 was the highest. Conclusion There are differences in the contents of trace elements in the whole blood of pregnant women at different ages or various gestation periods in Hangzhou,and it is suggested that pregnant women should check the levels of trace elements regularly,and reasonably supplement trace elements to their own body in order to meet the maternal and fetal demands,and then the chance for a healthy pregnancy and a heal
