Young adults born at extremely low birth weight (prenatal adversity; = 64 = 23.14 years, = 1.26 years) had a lower alpha/delta ratio score compared to normal birth weight controls ( 76, = 23.60 years, = 1.09 years), while youth exposed to child maltreatment (postnatal adversity; = 39, = 16.18 years, = 1.15) had a higher alpha/delta ratio compared to controls ( = 23, = 16.00 years = 1.50 years).
Our results suggest that being exposed to pre- and post-natal adversity may have different long-term consequences on brain development. We speculate that these differences might be associated with some of the different functional outcomes known to characterize each type of adverse experience.
与正常出生体重对照组( = 76,年龄 = 23.60 岁,标准差 = 1.09 岁)相比,极低出生体重(产前逆境; = 64,年龄 = 23.14 岁,标准差 = 1.26 岁)的年轻人阿尔法/德尔塔比率评分较低,而经历过儿童虐待(后天逆境; = 39,年龄 = 16.18 岁,标准差 = 1.15 岁)的年轻人与对照组( = 23,年龄 = 16.00 岁,标准差 = 1.50 岁)相比,阿尔法/德尔塔比率较高。
我们的结果表明,暴露于产前和产后逆境可能对大脑发育有不同的长期影响。我们推测,这些差异可能与已知每种类型的不良经历所具有的某些不同的功能结果有关。
