53 MATERNAL STRESS REFLECTED IN NEONATAL HAIR GC LEVELS CONCLUSION Maternal stress during pregnancy seems associated with suppressed fetal HPA axis activity, resulting from increased maternal HPA axis activity. Persistent maternal stress throughout pregnancywas associatedwith the largest decrease in neonatal hair GCs. Further studies are needed to estimate the clinical relevance of these findings on neurodevelopment, and mental and physical health.
