Insights

Maternal emotion regulation and autonomic function during pregnancy predict infant neurobehavioral patterns. Lower maternal stress and flexible autonomic responses are linked to better infant regulation.

Area of Science:

  • Developmental Psychology
  • Neuroscience
  • Maternal-Fetal Medicine

Background:

  • Newborn neurobehavior is a key indicator of early development.
  • Perinatal factors can influence infant neurobehavioral outcomes.
  • Understanding these predictors is crucial for early intervention.

Purpose of the Study:

  • To examine perinatal predictors of neurobehavioral patterns in healthy, low-risk infants.
  • To identify distinct infant neurobehavioral profiles using the NICU Network Neurobehavioral Scale (NNNS).
  • To explore associations between maternal emotion dysregulation and autonomic function (respiratory sinus arrhythmia - RSA) and infant neurobehavioral profiles.

Main Methods:

  • Latent profile analysis of NNNS data from 385 mother-infant dyads.
  • Maternal self-reported emotion dysregulation and RSA data collected during the third trimester.
  • Infant neurobehavior assessed ~24 hours after birth.

Main Results:

  • Three NNNS profiles were identified: high-attention/moderate-regulation (P1), low-arousal/high-lethargy (P2), and high-arousal/high-stress (P3).
  • Infants in P3 showed more dysregulated neurobehavior.
  • Lower maternal emotion dysregulation was associated with infants in P3 (vs. P2).
  • More flexible maternal RSA responses were linked to infants in P1 and P2 (vs. P3).

Conclusions:

  • The NNNS reliably identifies neurobehavioral profiles in healthy, term infants.
  • Maternal emotional wellbeing and autonomic flexibility during pregnancy are associated with specific infant neurobehavioral patterns.
  • Findings highlight the complex interplay between maternal state and fetal development.
