In utero infant’s stress response system impacted by mother’s psychological & physiological state
Developmental origins of infant stress reactivity profiles: A multi-system approach.
Author: Rash JA, et al (2016), Developmental Psychobiology
This study tested the hypothesis that maternal physiological and psychological variables during pregnancy discriminate between theoretically informed infant stress reactivity profiles. The sample size included 254 women and their infants. Maternal mood, salivary cortisol, respiratory sinus arrhythmia (RSA), and salivary alpha-amylase (sAA) were assessed at 15 and 32 weeks gestational age. Maternal stress biomarkers, along with self-reported psychological distress during pregnancy, discriminated between infant stress reactivity profiles. These results suggest that maternal psychological and physiological states during pregnancy have broad effects on the development of the infant stress response systems.
