Lancet Diabetes Endo:孕妇补充维生素D并不增加后代骨质含量

背景:有研究表明,孕妇维生素D状况与后代骨量有关,但不是所有的观察性研究都可得出这样的结论。在最近的一项随机对照试验中,研究人员发现,孕妇在孕期补充充足的维生素D并不能增加后代骨量。该研究旨在评估孕期补充维生素D比未补充维生素D的孕妇而言,生育的孩子全身骨矿物质含量(BMC)是否会更高。 


方式:母体维生素D骨质疏松研究(MAVIDOS)是一个多中心、双盲、随机、安慰剂对照实验,研究人员从英国三个研究地点(南安普顿、牛津大学和谢菲尔德)招募孕妇参与实验。参与的女性年龄>18岁,单胎妊娠且妊娠周期小于17周,孕10-17周时血清(25(OH)D)浓度为25-100 nmol/L。参与者被随机分配到实验组和对照组(1:1)。从孕14周起至分娩,实验组孕妇口服维生素D3 1000IU/天,对照组孕妇服用等量的安慰剂。参与者和研究人员不知道分配情况(双盲)。主要结果是使用双能X线吸收测定法(dualenergyX-rayabsorptiometry,DXA)探测出生2周的新生儿BMC,同时收集孕妇的分娩结果信息。

结果:2008年10月10日-2014年2月11日,研究人员随机选取了569名孕妇采用安慰剂治疗和565名孕妇口服维生素D3 1000IU/天。对照组中有370(65%)名婴儿、实验组中有367名(65%)新生儿。 实验组和对照组新生儿BMC无明显区别(61.6g[95%CI:60.3-62.8]:60.5g[59.3-61.7,p=0.21)。两组孕妇分娩结果无明显区别,但对照组的孕妇相比实验组而言产后出血发生率更高(96/569[17%]:65/565[12%],p=0.01)。研究期间没有不良事件发生。 

结论:研究表明,补充维生素D3 1000IU/天的的孕妇相比不补充的孕妇而言,后代的BMC并没有明显增加,但孕妇每天补充1000国际单位的维生素D3是安全的。
