225名育龄妇女孕前、孕中及产后微量元素调查

Survey on Microelements of Pre-pregnancy,Pregnancy and Postpartum Periods Among 225 Childbearing Age Women

目的了解育龄妇女在孕前、孕中及产后微量元素水平变化及影响因素,为育龄妇女营养保健提供科学依据。方法连续收集2009年1月-2011年5月在本院孕前、孕中检查及产后体检的225例育龄妇女血样,用原子吸收光谱分析仪检测Ca、Mg、Fe、Zn、Cu的含量。结果不同时期妇女全血中Ca、Mg、Fe、Zn、Cu含量呈偏态分布,孕期及产后铁缺乏常见(P<0.05)。另外,孕期和产后妇女锌、钙也总体偏低(P<0.05)。结论孕期及产后妇女微量元素营养状况处在一个较低的水平,提示应注意合理营养摄入,根据饮食习惯科学补充必需的微量元素,适当加强锻炼,对体内胎儿发育及自身恢复都有一定的意义。

Objective To investigate the levels and influencing factors of the microelements in pre-pregnancy,pregnancy,and postpartum periods among the childbearing age women,and to offer the scientific evidence for the health care of childbearing age women. Methods We collected the blood samples of 225 childbearing age women who received the examination during the pre-pregnancy,pregnancy,and postpartum periods in the Maternal and Child Health Hospital of Hunan Province from January 2009 to May 2011.Atomic absorption spectrometer was used to detect the contents of Ca,Mg,Fe,Zn,and Cu in serum. Results The levels of Ca,Mg,Fe,Zn,and Cu showed a skewed distribution in different periods.The deficiency of Fe was common in the pregnancy and postpartum periods（P0.05）;and moreover,the levels of Zn and Ca were generally lower in the pregnancy and postpartum periods（P0.05）. Conclusions The levels of the microelements in the pregnancy and postpartum periods are lower,which suggest that it has significance to the growth of fetus and the recovery of puerpera through scientific intake of the nutrition and necessary microelements according to the eating habits and strengthening the physical exercises.
