Course of ante- and postnatal depressive symptoms related to mothers' HPA axis regulation.

Given high health costs of depression during pregnancy and the first postnatal year, it is important to understand mechanisms involved in the emergence and perpetuation of symptoms during this time. In a series of 2 studies, we aim to clarify bidirectional relations between mothers' physiological stress regulation-stress-related activation of the hypothalamic-pituitary-adrenal (HPA) axis-and their course of depressive symptoms. In Study 1, 230 pregnant women recruited from a women's mental health program gave 3 saliva samples in the context of psychosocial stress at 24, 30, and 36-weeks gestation. They self-reported depressive symptoms across the three trimesters of pregnancy and first year postpartum. Multilevel models revealed women with elevated salivary cortisol during pregnancy showed a course of escalating ante- and postnatal symptoms, implicating HPA hyperactivation as a precursor to worsening mood problems. In Study 2, 54 mothers from a community sample self-reported depressive symptoms at 3, 6, 12, and 18 months postnatal. At 18 months, they participated in a dyadic stress task with their infant and gave 4 saliva samples for cortisol assay. For mothers with a lifetime depression diagnosis, an escalating course of postnatal symptoms predicted a higher, flatter cortisol response profile. Together, the results of these studies suggest that for high-risk mothers, a trajectory of worsening depression may both follow from and give rise to neuroendocrine stress hyperactivation. These findings suggest greater attention is warranted to course of depressive symptoms across the ante- and postnatal period, rather than symptom levels at any given time, to characterize health risks.

Depression and anxiety symptoms of mothers of preterm infants are decreased at 4 months corrected age with Family Nurture Intervention in the NICU.

Preterm delivery can precipitate maternal psychological morbidities. Family Nurture Intervention (FNI) was designed to minimize these by facilitating the emotional connection between mother and infant, beginning early in the infant's neonatal intensive care unit (NICU) stay. We examined depression and anxiety symptoms of mothers of preterm infants at 4 months infant corrected age (CA). One hundred fifteen mothers who delivered between 26 and 34 weeks gestational age were randomized to receive standard care (SC) or standard care plus FNI. Mothers' self-reported depressive symptoms (Center for Epidemiologic Studies Depression Scale: CES-D) and state anxiety (Spielberger State-Trait Anxiety Inventory: STAI) symptoms were assessed at enrollment, near to term age, and 4 months (CA). At 4 months CA, mean CES-D and STAI scores were significantly lower in FNI mothers compared to SC mothers. Effectiveness of FNI can only be evaluated as an integrated intervention strategy as it was not possible to control all aspects of FNI activities. Although there was considerable loss to follow-up, analyses suggest that resulting biases could have masked rather than inflated the measured effect size for depressive symptoms. FNI may be a feasible and practicable way to diminish the impact of premature delivery on maternal depressive and anxiety symptoms.

Family nurture intervention improves the quality of maternal caregiving in the neonatal intensive care unit: evidence from a randomized controlled trial.

OBJECTIVE: This study assessed the impact of Family Nurture Intervention (FNI) on the quality of maternal caregiving behavior (MCB) while in the neonatal intensive care unit (NICU). FNI is a randomized controlled trial conducted in a high-acuity NICU to facilitate an emotional connection between mothers and their premature infants. FNI begins shortly after birth, continues until discharge, and involves mother/infant calming sessions that include scent cloth exchange, vocal soothing and emotion expression, eye contact, skin-to-skin and clothed holding, and family-based support sessions. METHODS: Maternal caregiving behavior was coded during a single holding and feeding session (∼30 min) in the NICU before discharge at approximately 36 weeks gestational age (GA). Sixty-five mothers and their premature infants (34 male, 31 female; 26-34 wk GA) were included in these analyses (FNI, n = 35; standard care [SC], n = 30). RESULTS: Relative to mothers in the SC condition, those in the FNI group showed significantly higher quality MCB, which remained significant when controlling for birth order, twin status, maternal depression, and maternal anxiety. CONCLUSION: This is the first study to demonstrate that in-unit MCB can be enhanced by a hospital-based intervention. FNI provides a new rationale for integrating nurture-based interventions into standard NICU care.
