研究人员在近期出版的《儿科学杂志》上刊文强调指出,与足月分娩婴儿相比,早产儿的大脑体积明显减小;且早产的这一特别影响取决于婴儿性别,早产男婴对脑白质(WM)的减少更为敏感,而另一方面,早产女婴的神经解剖学变量与认知结果间强烈相关。来自于美国斯坦福大学医学院的 Allan L.Reiss 教授及其同事对此解释指出,高达50%的极低出生体重婴儿有神经发育障碍,在小学期间需要特别帮助并加以治疗;但出现这些差异的潜在机制尚不甚清楚。
In a recent issue of the Journal of Pediatrics, the researchers emphasized that the brain volume of premature babies was significantly reduced compared with full-term babies and that this particular impact of prematurity was dependent on the sex of the infant, Decreased white matter (WM) is more sensitive, whereas on the other hand, the neurological anatomical variables in preterm infants are strongly correlated with cognitive outcomes. Professor Allan L. Reiss and colleagues from the Stanford University School of Medicine in the United States explain that up to 50% of very low birth weight infants have neurodevelopmental disorders that require special help and treatment during primary school; however, these differences The underlying mechanism is not yet clear.
