Eur J Nutr:妊娠期母体补充叶酸对1月龄婴儿神经发育的影响

2019-07-15 sunshine 译 MedSci原创

本研究旨在探讨孕期补充母体叶酸(FA)对1月龄婴儿神经发育的影响,并确定其影响是否与母体循环炎性细胞因子的浓度有关。这项出生队列研究于2015年7月至2017年7月期间在中国天津招募了1186对母婴参与者。这些女性在怀孕期间完成了关于其生活方式和FA补充的访谈者管理问卷。使用标准神经心理学检查表评估1月龄婴儿的神经发育。选择192名女性,在其妊娠16-18周测量血清同型半胱氨酸(Hcy)和炎性细胞

本研究旨在探讨孕期补充母体叶酸(FA)对1月龄婴儿神经发育的影响,并确定其影响是否与母体循环炎性细胞因子的浓度有关。

这项出生队列研究于2015年7月至2017年7月期间在中国天津招募了1186对母婴参与者。这些女性在怀孕期间完成了关于其生活方式和FA补充的访谈管理问卷。使用标准神经心理学检查表评估1月龄婴儿的神经发育。选择192名女性,在其妊娠16-18周测量血清同型半胱氨酸(Hcy)和炎性细胞因子的浓度。

结果显示,母亲怀孕期间服用FA补充剂的婴儿的发育商(DQ)明显高于母亲未服用者(P <0.05)。校正母体特征后,与未补充FA的女性相比,使用补充性FA使用1-3个月,3-6个月和> 6个月与其婴儿DQ评分比例分别增加7.7,11.0和7.4个单位相关(P <0.05)。FA补充与血清Hcy浓度降低相关(β= 0.19),这与妊娠16-18周时女性血清炎症细胞因子浓度相关(β= 0.57)。母体血清炎性细胞因子浓度与1月龄婴儿后代的DQ评分呈负相关(β= 0.22)。

总之,该研究结果表明,怀孕期间母亲FA补充有利1月龄婴儿后代的神经发育。这种关联是通过整个妊娠期间血清Hcy和炎性细胞因子浓度的变化来介导。
