Conclusions
PRETERM BIRTH, SECONDARY
In this secondary analysis of the IPISTOSS randomized clinical trial, SSC practiced between a parent and a very preterm infant in the immediate postpartum period after birth enhanced child interactive behaviors and positive affect at 4 months of corrected infant age. Skin-to-skin contact may also benefit the dyadic aspects of interaction. These findings support the existence of a sensitive period after very preterm birth, during which close contact between parent and infant may induce a long-term positive effect on the parent-infant relationship. To support infant long-term development, clinical practices should consider the place of care to be in immediate direct SSC with a parent after birth, alongside other necessary nursing and medical care.
