孕妇毛发矿物质水平与新生儿毛发矿物质水平及体质发育的相关性

Study on relation between concentration of mineral levels in pregnant woman's and neonatal baby's hair, and fetal development

目的了解孕妇毛发中锌、铁、铜、铅、钙、镁6种矿物质的水平及与新生儿毛发中上述矿物质和生长发育指标之间的关系。方法定点抽取医院产科分娩的孕妇,收集孕妇、新生儿的毛发样本进行检测,同时对新生儿身体发育指标进行测量,并将收集的数据进行相关统计分析。结果孕妇毛发中锌、铁、钙含量与新生儿毛发中的锌、铁、钙含量呈正相关,相关系数分别为0.71,0.47,0.46;新生儿发育指标体重、身长、头围和胸围与孕妇毛发中锌、铁、钙元素的含量呈正相关。结论孕期妇女锌、铁、钙元素水平的变化,可以影响新生儿的体质发育,孕妇应该注意适时补充锌、铁和钙元素。

Objective To examine the relation between zinc, iron, copper, magnesium, calcium and plumbum levels in pregnant woman＇s hair and those mineral levels in neonatal baby＇s hair and the development of baby in womb. Methods Some pregnant women and their new born babys in certain hospital were selected as subjects. The hair samples of pregnant woman and their neonatal babys were collected for determining the microelements during hospitalization period, and the development indexes of baby were measured at the same time. Results The zinic, iron and calcium levels in pregnant women＇ hair were positively correlated to those levels in neonatal babys＇ hair, with the correlation coefficients of 0. 71, 0. 47, and 0.46 respectively. The baby＇s weight, body length, head circumference and chest circumference were positively correlated to the zinic, iron and calcium levels in pregnant women＇ hair. Conclusion The nutritional level of zinc, iron and calcum of pregnant woman can influence the fetal development, and the pregnant women should supply these nutrients in time.
