【摘要】 目的 探讨孕妇与新生儿之间维生素D和钙的关系。方法 采用竞争性蛋白结合法(EPBA)对40例正常孕妇及其新生儿血清进行25羟维生素D测定，并同时检测了血清钙。结果 孕妇与其新生儿血清维生素D水平有相关性(r=0.147，P<0.01)，孕妇血清维生素D水平(19.7±18.24)nmol/L高于新生儿(11.79±12.07)nmol/L。孕妇与其新生儿血清钙水平无相关性，(r=0.110，P>0.05)，孕妇血清钙水平(2.34±0.11)mmol/L低于新生儿(2.60±0.16)mmol/L。结论 胎儿的维生素D是母体依从性的，而胎儿的钙离子是掠夺性的。孕妇缺钙是绝对的，缺维生素D是相对的。孕妇应重点补钙，适当补维生素D。
