JAMA:孕妇补充多种微营养素与铁叶酸合剂对婴儿6个月内健康没有差异

2015-02-23 MedSci译 MedSci原创

孕妇应该补充多元维微营养(如复合维生素)还是补充铁-叶酸对婴儿的健康和存活还有争议,目前也没有严谨的科学证据支持。最近在南亚孟加拉国对此进行的一项研究,旨在阐明在产前补充多种微量营养素,和补充常规的铁-叶酸片对婴儿致死率的影响。 研究采用群组随机双盲的研究方法,从2007年12月开始招募,至2012年8月研究结束,至研究结束,所有婴儿随访达到6个月。在此期间共纳入127282名女性,


孕妇应该补充多元维微营养(如复合维生素)还是补充铁-叶酸对婴儿的健康和存活还有争议,目前也没有严谨的科学证据支持。最近在南亚孟加拉国对此进行的一项研究,旨在阐明在产前补充多种微量营养素,和补充常规的铁-叶酸片对婴儿致死率的影响。

研究采用群组随机双盲的研究方法,从2007年12月开始招募,至2012年8月研究结束,至研究结束,所有婴儿随访达到6个月。在此期间共纳入127282名女性,44567位孕妇,最终28516位活婴被分析。招募时孕妇的中位孕周为9周时。

受试者分别提供一种含有15种微量营养素的补充剂,另外一组给予铁-叶酸合剂,每天补充,从早孕开始到产后12周。主要终点为180天时婴儿的全因死亡率。次要终点包括死胎,早产(<37周),低出生体重(<2500g)。但是次要终点的统计学意义的P值设为<0.01。

结果表明,在22405位孕妇补充了15种微营养素,22162名孕妇补充了铁叶酸合剂,分别出生了活婴14374名和14142名。在6个月时,并没有发现多种微营养补充剂能减少婴儿致死率。在铁叶酸合剂组为764名死亡婴儿(54.0/1000活产),在多种微营养剂组为741名死亡(51.6/1000活产),两组相比RR=0.95,95%CI:0.86-1.06。在死胎方面,多种营养素补充剂没有显著减少死胎发生,两组死胎分别为43.1/1000, 48.2/1000,RR=0.89,95%CI:0.81-0.99,p=0.02,但是显著减少早产(18.6/1000 vs. 21.8/1000, RR=0.85, 95%CI:0.80-0.91, p<0.001),也显著减少低体重儿(40.2/1000 vs. 45.7/1000,RR=0.88, 95%CI:0.85-0.91,p<0.001)

上述结果表明,在孟加拉国,产前无论是补充多种微营养素还是铁叶酸合剂,对于婴儿6个月内的全因死亡率没有显著性差异;但是多种微营养素可以减少早产和低体重儿,但是在死胎方面无统计学意义。
