Sammanfattning

Background: A novel biomarker of aging at birth, namely epigenetic
gestational age (GA) based on DNA methylation in fetal cord
blood, has been recently developed to accurately estimate GA at
birth. We examined whether this aging biomarker prospectively
predicted psychiatric problems during early childhood.
Methods: 407 mothers from the PREDO Study filled in the Child
Behavior Checklist at child’s mean age of 3.7 (SD = 0.75) years. DNA
was extracted from cord blood and methylation was analyzed with
Illumina 450k array. DNA methylation (DNAm) GA of fetal cord
blood DNA was calculated from 148 CpG sites shown to have high
accuracy in predicting chronological GA. Epigenetic GA was calculated
as arithmetic difference betweenDNAmGAand chronological
GA.
Results: In boys only child lower epigenetic GA (lower DNAm
GA compared to chronological GA) was prospectively associated
with higher total behavioral (p = 0.047), emotionally reactive
(p = 0.035), and withdrawn (p = 0.004) problems in models adjusting
for chronological GA, cord blood cell-type composition, genetic
population stratification, and child age at the time of testing.
Conclusions: Epigenetic GA immaturity seems to be developmentally
disadvantageous for boys, who in early childhood show
higher psychiatric problems in maternal reports.
