Neural correlates of inhibitory control in the context of infant cry and paternal postpartum mental health.

BACKGROUND: Inhibitory control, a form of self-regulation, may support sensitive parenting, but has been understudied in new fathers despite their pronounced risk for stress and mental health challenges. METHODS: This study probed the neural correlates of inhibitory control and its associations to first-time fathers' postpartum mental health, focusing on depressive symptoms, state anxiety, and perceived stress. Six months after their child's birth, 38 fathers self-reported on their mood, anxiety, and stress, and performed a Go/No-Go fMRI task while listening to three sets of sounds (infant cry, pink noise, and silence). RESULTS: Fathers' behavioral inhibition accuracy was consistent across the sound conditions, but their patterns of neural activation varied. Compared to the pink noise condition, fathers showed heightened engagement in prefrontal regulatory regions when self-regulating during the infant cry and silent conditions. When examining correct trials only, results in visual motor area and primary somatosensory cortex emerged only for infant cry and not for pink noise and silence. Moreover, fathers reporting higher levels of postpartum depression, state anxiety, and perceived stress showed greater activation in prefrontal regions when inhibiting during infant cry or silence. CONCLUSION: This study is the first to underscore the complex interplay between the neural mechanisms related to inhibitory control and postpartum mental health and stress across varied auditory context, laying the groundwork for future research.

Maternal prenatal social contact during the COVID-19 pandemic predicts infant birth weight.

BACKGROUND: Social connectedness and mental health have been associated with infant birth weight, and both were compromised by the COVID-19 pandemic. AIMS: We sought to examine whether changes in maternal prenatal social contact due to the COVID-19 pandemic were associated with infant birth weight and if maternal prenatal mental health mediated this association. STUDY DESIGN: A longitudinal study of mothers and their infants born during the first wave of the COVID-19 pandemic. SUBJECTS: The sample consisted of 282 United States-based mother-infant dyads. OUTCOME MEASURES: Depressive symptoms were measured with the Beck Depression Inventory-II, anxiety was measured with the State Anxiety Inventory, and stress was measured using the Perceived Stress Scale 14. We also asked participants about pandemic-related changes in social contact across various domains. Adjusted birth weight was calculated from birth records or participant-report when birth records were unavailable. RESULTS: Decreases in social contact during the pandemic were associated with lower adjusted infant birth weight (B = 76.82, SE = 35.82, p = .035). This association was mediated by maternal prenatal depressive symptoms [Effect = 15.06, 95 % CI (0.19, 35.58)] but not by prenatal anxiety [95 % CI (-0.02, 32.38)] or stress [95 % CI (-0.31, 26.19)]. CONCLUSION: These findings highlight concerns for both mothers and infants in the wake of the COVID-19 pandemic, since birth weight can have long-term health implications and the social restructuring occasioned by the pandemic may lead to lasting changes in social behavior.

The birth of a story: Childbirth experiences, meaning-making, and postpartum adjustment.

The present study investigated how meaning-making around a birth experience predicts relationship quality and parenting stress across the transition to first-time parenthood, a time that many new parents find stressful and challenging. Childbirth experiences may set the stage for these challenges, and how new parents make meaning of childbirth could play a role in their subsequent postpartum adjustment. Meaning-making processes (sense making, benefit finding, and changes in identity) were coded from birth narratives collected from 77 mixed-sex biological parent dyads (n = 154 individuals) shortly after the birth of their first child. Parents reported on their relationship quality during pregnancy and at 6 months postpartum, and on their parenting stress postpartum. Mothers' greater sense making and benefit finding buffered longitudinal declines in their own relationship quality, and maternal sense making also buffered declines for fathers. Fathers' greater sense making and benefit finding predicted lower levels of their own parenting stress, whereas mothers' greater sense making and benefit finding were linked with higher paternal parenting stress. Finally, fathers' discussion of changes in identity predicted lower levels of parenting stress in mothers. These results suggest the importance of meaning-making following childbirth for couples adjusting to parenthood and highlight the value of studying meaning-making processes dyadically. Clinicians may be able to support new parents by facilitating their coconstruction of meaning during their shared birth experience and transition to parenthood.
