N Engl J Med:妊娠期补充维生素D宝宝长的高?然并卵

2018-08-29 佚名 环球医学网

当前,环境和饮食对胎儿和婴儿身高的影响,仍有很多未知。观察性研究表明,产前营养干预早期暴露与后来的人体测量结局有关,但是其对儿童线性生长影响的证据有限。小于胎龄儿(SGA)和产后线性增长受限,仍然是低和中等收入国家的主要公共卫生问题。

当前,环境和饮食对胎儿和婴儿身高的影响,仍有很多未知。观察性研究表明,产前营养干预早期暴露与后来的人体测量结局有关,但是其对儿童线性生长影响的证据有限。小于胎龄儿(SGA)和产后线性增长受限,仍然是低和中等收入国家的主要公共卫生问题。

维生素D可能通过影响钙吸收、甲状旁腺激素(PTH)表达、磷酸盐代谢、生长板功能、胰岛素样生长因子轴的调节,影响胎儿和出生后婴儿的生长。观察性研究和临床试验的Meta分析表明,维生素D或对胎儿生长具有有益作用,但既往的大多数研究有严重的方法学局限性。

在孟加拉共和国,约30%的新生儿是SGA,5岁以下儿童36%发育不良(身长-年龄z评分<?2)。孟加拉共和国育龄期女性普遍缺乏维生素D。

在常见维生素D缺乏的地区,母亲妊娠期和哺乳期补充维生素D是否能改善胎儿和婴儿生长,目前仍不清楚。2018年8月,发表在《N Engl J Med》的一项在孟加拉共和国进行的随机、双盲、安慰剂对照试验对此进行了分析。

在该项研究中,根据世界卫生组织(WHO)儿童生长标准,研究人员每周评估产前补充维生素D(从17~24孕周直到出生或产后6个月),合并和不合并产后补充维生素D,对主要结局1岁时婴儿身长-年龄z评分的影响。

研究对象被随机分成5组:产前或产后未接受维生素D(安慰剂组)、产前补充4200 IU(产前4200组)、产前补充16800 IU(产前16800组)、产前补充28000IU(产前28000组)、产前及产后26周补充28000 IU(产前和产后28000组)。

结果显示,在1岁时评估的1164名婴儿(1300例妊娠的89.5%)中,各组间的平均(±SD)身长-年龄z评分没有显着差异。评分如下:安慰剂组,?0.93±1.05;产前4200组,?1.11±1.12;产前16800组,?0.97±0.97;产前28000组,?1.06±1.07;产前+产后28000组,?0.94±1.00(P=0.23)。各组间的其他人体测量指标、出生结局和发病率也没有显着差异。

对于母亲和婴儿血清25-羟基维生素D和钙浓度、母亲尿钙排泄和母亲甲状旁腺激素浓度,维生素D补充剂有预期的影响。

各组间不良事件的频率没有显着差异,但在接受最高剂量的女性中高钙尿症的发生率较高。

作者认为,在普遍孕前维生素D缺乏和胎儿和婴儿生长受限的人群中,孕中期至出生或产后6个月,母亲补充维生素D不会改善胎儿或婴儿生长。

自从怀孕后,爸爸妈妈们就一直为宝宝的营养问题伤透脑筋,维生素D补充剂是大多数孕妇的必选之一,但该研究结果却表明无效!

看来,决定宝宝身高最重要的因素,还是先天基因。人为施加影响,无论如何努力,都效果甚微。
