Pediatrics:当怀孕遭遇维生素D缺乏,要继续补充D吗?

2015-10-13 Mechront 译 MedSci原创

研究者进行了一项研究,比较以下两种方式补充维生素D3的有效性:给产妇每天补充6400 IU维生素D3;给婴儿每天补充400 IU维生素D3。该研究纳入了产后4-6周的哺乳期产妇,将其随机分到3组,分别给予维生素D3 400、2400、6400 IU/d,持续6个月。对400IU/d组的母乳喂养婴儿给予口服维生素D3 400IU/d;另外两组产妇的婴儿则不额外补充维生素D3。当25(OH)D <

研究者进行了一项研究,比较以下两种方式补充维生素D3的有效性:给产妇每天补充6400 IU维生素D3;给婴儿每天补充400 IU维生素D3。

该研究纳入了产后4-6周的哺乳期产妇,将其随机分到3组,分别给予维生素D3 400、2400、6400 IU/d,持续6个月。对400IU/d组的母乳喂养婴儿给予口服维生素D3 400IU/d;另外两组产妇的婴儿则不额外补充维生素D3。当25(OH)D <50 nmol/L时定义为维生素D缺乏。该研究中产妇补充维生素D3 2400IU/d组在2009年结束试验,因为越来越多的婴儿发生维生素D缺乏。纳入研究时以及研究开始后每个月检测产妇血清维生素D、25(OH)D、钙、磷浓度,以及尿中钙/肌酐清除率。婴儿在纳入研究和4个月、7个月时检测了相关血液指标。

共有334对400IU和6400IU母亲-婴儿参与这项研究,其中216(64.7%)一直母乳喂养;148 (44.3%)纯母乳喂养至4个月;95 (28.4%)至7个月。母乳喂养里维生素D缺乏的婴儿有着严重的种族差异。与400IU/d组相比,6400IU/d组更安全,并且妈妈体内维生素D以及25(OH)D含量较纳入时增高明显(P < .0001)。婴儿之间的比较发现,每天口服维生素D 400IU的婴儿(产妇400IU/d)与每天没有服用维生素D的婴儿(产妇6400IU/d),两组血液相关指标并没有发现有什么统计学意义。

研究结果表明,对哺乳期产妇每天补充6400IU维生素D不仅是安全的,同时通过母乳喂养也能满足婴儿的需求。
