JAMA:捐赠母乳一定优于配方奶吗?

2016-11-10 MedSci MedSci原创

许多极低出生体重儿(VLBW)没有得到足够的母乳,需要额外补充巴氏杀菌的捐赠母乳或早产儿配方奶。 本研究的目的是,营养丰富的捐赠母乳 vs 早产儿配方奶,均作为母乳的补充,能否降低VLBW的新生儿发病率、支持生长、改善其神经发育。 在这种务实、双盲、随机试验中,从加拿大安大略4个新生儿单位招募VLBW婴儿,出生于2010年10月至2012年12月,出生96小时内被纳入研究,随访到201

极低出生体重儿(VLBW)没有足够的母乳喂养,需要额外补充巴氏杀菌的捐赠母乳或早产儿配方奶。那么,相对于母乳,捐赠母乳或早产儿配方奶,能否促进VLBW生长,改善其神经发育呢?
 
尽管现有评估母乳益处的数据有限,但是母乳诸多优点也导致了捐赠母乳的增多。近期,发表在顶级医学杂志JAMA上的一篇研究文章,旨在探讨营养丰富的捐赠母乳 vs 早产儿配方奶,均作为母乳的补充,能否降低VLBW的新生儿发病率、支持生长和改善其神经发育。
 
在这项实用性双盲随机对照研究中,从加拿大安大略4个新生儿单位招募VLBW婴儿,出生于2010年10月至2012年12月,出生96小时内的极低出生体重儿被纳入研究,研究者随访到2015年7月。
 
主要结果是矫正年龄18月龄的贝利婴幼儿发展量表(第三版(Bayley III))的认知综合得分。
次要终点包括Bayley-III语言和运动综合得分、生长和二元发病率和死亡率指数。 
 
840例符合条件的婴儿中,363例(43.2%)被随机化分组(捐赠母乳组和配方奶组分别有181例和182例),对299 (92%)例幸存者进行神经发育评估。
 
平均出生体重和婴儿的胎龄分别为996 (SD, 272) g和27.7 (2.6)周,195 (53.7%)为男婴。组间以下方面的差异无统计学意义:Bayley-III认知总分(捐赠母乳组和配方奶组的调整后的分数分别为92.9和94.5,完全校正后的平均差, −2.0 [95% CI, −5.8 to 1.8]),语言综合评分(87.3 vs 90.3,平均差,−3.1 [95% CI, −7.5 to 1.3]),运动得分(91.8 vs 94.0;平均差, −3.7 [95% CI, −7.4 to 0.09])。二元发病率和死亡率指数(43% vs 40%)或生长z分数变化也没有组间差异。
 
结果表明,对于极低出生体重儿,与应用早产儿配方奶相比,营养丰富的捐赠母乳并不能改善早产儿年龄在校正年龄18月龄的神经发育。

母乳喂养的秘密:生成大量的双核细胞

沃尔特和伊莱扎霍尔研究所的研究人员发现了哺乳期有丰富的奶产量的秘密之一。他们的研究表明,乳腺细胞发育了两个细胞核可以作为乳房开关来哺育新生儿。这种变化在怀孕后期发生,生成大量的两核细胞。 Jane Visvader教授和研究人员发现这些两核细胞在哺乳期停止后就消失了,乳腺细胞回归到单个核状态。该文近期发表在《自然通讯》杂志上。 Rios博士和Fu博士使用独特的三维成像技术发现大量的细胞变成

Am J Clin Nutr:哺乳期女性可以随便吃喝吗?

母乳是婴儿成长最自然、最安全、最完整的天然食物,它含有婴儿成长所需的所有营养和抗体,特别是母乳含有百分之五十的脂肪,除了供给宝宝身体热量之外,还满足宝宝脑部发育所需的脂肪(脑部60%的结构来自于脂肪);丰富的钙和磷可以使宝宝长的又高又壮;免疫球蛋白可以有效预防及保护婴儿免于感染及慢性病的发生;比非得因子和寡糖可以抑制肠道病菌增生和帮助消化。除此之外,哺喂母乳的亲密接触和亲子关系可刺激婴儿脑部及心智

母乳期喂养的婴儿使用抗生素的后果

一项新的研究表明,抗生素的使用可能会影响母乳喂养的一些益处。研究人员发现,处于母乳喂养期的婴儿使用抗生素会引起它们易于感染和肥胖。芬兰赫尔辛基大学免疫学专家Katri Korpela说道,“母乳与奶粉不同,婴儿接受来自母亲的细菌和一些特定的糖类以促进自身的生长。”研究预示着母乳喂养对婴儿的健康益处主要是依赖它是如何帮助婴儿建立起肠道健康的微生物环境。然而,抗生素的使用会打破婴儿体内的这一过程。Ko

Am J Clin Nutr:早期母乳喂养对后代端粒长度的影响

背景:端粒长度(TL)是细胞老化的一个标志,其终身消耗的大部分发生于生命前4年。鲜为知的是,儿童端粒缩短的危险因素。目的:生命早期不同喂养和学龄前儿童TL的关系。方法:纳入了121名拉丁美洲的孩子,评估了饮食、喂养和体重相关危险因素与儿童4岁(n = 108)、5岁(n = 92)大小时的TL长度的关系。有77名儿童的喂养变量进行了重复测量。结果:TL平均长度与下列因素有关:4-6周时纯母乳喂养(

Am J Clin Nutr:配方奶的蛋白含量并不是越高越好

对于不完全母乳喂养的婴儿,在婴儿期摄入高蛋白饮食,可能会增加以后肥胖的风险。降低婴儿配方奶粉中的蛋白质含量,使其更接近成熟母乳,可能会降低配方奶喂养婴儿的超重或肥胖长期风险。 通过与WHO生长标准和母乳喂养婴儿进行比较,我们评估了含1.8 g/100 kcal蛋白(低于目前大多数配方奶,更接近母乳)的乳清蛋白为主的配方奶对婴儿生长发育的影响。 使用来自11项随机对照试验的健康足月婴儿(

Pediatr Obes:不想孩子变胖,请多纯母乳喂养!

众所周知母乳里含有最适合婴幼儿生长的成分和比例,无论是生长发育还是增强免疫力,母乳喂养都是不二首选。当今社会还有一个热点话题“肥胖”,不仅会影响一个人的体型外表,还会增加多种疾病风险,所以“避免肥胖”也是许多人关心的问题。近期有研究表明,增加母乳喂养时间,可降低后代2岁时的肥胖风险。加利福尼亚斯坦福大学医学院医学系教授Sepideh Modrek博士和同事基于2009年出生在俄勒冈和2011-20
