Parent-Training with Kangaroo Care Impacts Infant Neurophysiological Development & Mother-Infant Neuroendocrine Activity

Abstract

A randomized control trial was conducted to investigate the effects of skin-to-skin, chest-to-chest contact (kangaroo care, KC) in mother-infant dyads on patterns of infant brain activity and associated mother-infant neurohormone releases. 33 mother-infant dyads participated during pregnancy (29–38 weeks gestation), at neonatal and 3-month periods. Overall, analyses indicated that: 1) infants in the KC group showed left frontal brain activation patterns (asymmetry and coherence) associated with KC training; 2) KC produced moderate to large increases in oxytocin levels; and 3) KC yielded moderate decreases in cortisol reactivity. Findings suggest KC may garner favorable neuro-maturational and neurobiological outcomes for dyads.
