研究的主要作者Robert Boyle表示:“儿童食物过敏和湿疹是世界各地日益严重的问题。虽然有建议称女性在怀孕期间服用的膳食补充剂可能会影响婴儿过敏或湿疹的风险,到现在为止还从来没有这样的数据综合分析。”

来自伦敦帝国学院的一个研究小组分析了大量有关妊娠期、哺乳期或婴儿出生后第一年各种膳食补充剂的影响以及它们与未来宝宝过敏或自身免疫性疾病的风险之间的联系。研究发现孕妇食用鱼油和益生菌会对婴儿产生积极影响。

研究人员在分析益生菌,主要是鼠李糖乳杆菌时发现,当女性在孕晚期或是哺乳期服用胶囊形式的益生菌时,一个孩子患湿疹的风险降低了22%。该研究指出,任何可以解释这种相关性的机制仍然未知。

在鱼油方面,研究发现强有力的证据表明,女性在怀孕期间服用OMEGA-3脂肪酸补充剂可使婴儿鸡蛋过敏减少30%,并使花生过敏减少38%。虽然OMEGA-3摄入提供了好处,但OMEGA-6脂肪酸对婴儿的过敏风险没有任何影响。

这项研究的最终建议是怀孕女性在怀孕36周和前六个月哺乳期期间每日服用益生菌补充剂。另外在怀孕20周后开始服用鱼油补充剂,并持续到约前4个月哺乳期。

该研究发表在《PLOS Medicine》杂志上。
