This study explores the associations between maternal stress, breastmilk composition, and feeding and neurodevelopment for preterm infants in the NICU and at 4 months corrected age.
The proposed study will address our novel hypothesis that maternal stress is associated with feeding outcomes and markers of impaired neurodevelopment for preterm infants and alters human milk and infant gut profiles in ways that affect preterm neurodevelopment. Mothers and their preterm infants (28-34 weeks gestation at birth) will be recruited to determine if: (1) variation in postnatal stress among mothers of very preterm infants relates to the total volume or proportion of maternal milk provided to her infant in the NICU and if (2) variation in maternal postnatal stress relates to her pre…
