Infant Development and Preterm Care

To explore the interplay of maternal depressive symptoms on the infant limbic-hypothalamic-pituitary axis (LHPA) and neurological development. Pregnant women were monitored for depressive symptoms using the Beck Depression Inventory (BDI) at 28, 32, and 37 weeks of gestation and at delivery. A mixture growth curve analysis divided the women into three risk groups: low/stable, intermediate, and high/increasing depression based on BDI scores. The infant neuroendocrine system was examined using cord blood for adrenocorticotrophic hormone (ACTH) and cortisol measurements. Two-week-old infants were examined using Neonatal Intensive Care Unit Neurobehavioral Scale (NNNS). Infants born to women of the high/increasing depression group had significant ACTH elevation at birth. On NNNS examination, these infants were more hypotonic and habituated to auditory and visual stimuli. When compared to non-depressed women, maternal depressive symptoms, even in the absence of major depressive disorder, appeared to facilitate a different developmental pathway for the infant LHPA and early neurological development.
