Intergenerational Risk And Resilience Pathways From Discrimination And Acculturative Stress To Infant Mental Health, Sabrina R. Liu, Curt A. Sandman, Elyssia Poggi Davis, Laura M. Glynn

Psychology Faculty Articles and Research

Preconception and prenatal stress impact fetal and infant development, and women of color are disproportionately exposed to sociocultural stressors like discrimination and acculturative stress. However, few studies examine links between mothers’ exposure to these stressors and offspring mental health, or possible mitigating factors. Using linear regression, we tested associations between prenatally assessed maternal acculturative stress and discrimination on infant negative emotionality among 113 Latinx/Hispanic, Asian American, Black, and Multiethnic mothers and their children. Additionally, we tested interactions between stressors and potential pre- and postnatal resilience-promoting factors: community cohesion, social support, communalism, and parenting self-efficacy. Discrimination and acculturative stress were related …

Prenatal Maternal Mood Entropy Is Associated With Child Neurodevelopment, Mariann A. Howland, Curt A. Sandman, Elysia Poggi Davis, Hal S. Stern, Michael Phelan, Tallie Z. Baram, Laura M. Glynn

Psychology Faculty Articles and Research

Emerging evidence indicates that the predictability of signals early in life may influence the developing brain. This study examines links between a novel indicator of maternal mood dysregulation, mood entropy, and child neurodevelopmental outcomes. Associations between prenatal maternal mood entropy and child neurodevelopment were assessed in 2 longitudinal cohorts. Maternal mood was measured several times over pregnancy beginning as early as 15 weeks’ gestation. Shannon’s mood entropy was applied to distributions of mothers’ responses on mood questionnaires. Child cognitive and language development were evaluated at 2 and 6–9 years of age. Higher prenatal maternal mood entropy was associated with lower …

Prenatal Maternal Psychological Distress And Fetal Developmental Trajectories: Associations With Infant Temperament, Mariann A. Howland, Curt A. Sandman, Elyssia Poggi Davis, Laura M. Glynn

Psychology Faculty Articles and Research

Associations between prenatal maternal psychological distress and offspring developmental outcomes are well documented, yet relatively little research has examined links between maternal distress and development in utero, prior to postpartum influences. Fetal heart rate (FHR) parameters are established indices of central and autonomic nervous system maturation and function which demonstrate continuity with postnatal outcomes. This prospective, longitudinal study of 149 maternal–fetal pairs evaluated associations between prenatal maternal distress, FHR parameters, and dimensions of infant temperament. Women reported their symptoms of psychological distress at five prenatal visits, and FHR monitoring was conducted at the last three visits. Maternal report of infant …

Characterizing Prenatal Maternal Distress With Unique Prenatal Cortisol Trajectories, Gage Peterson, Emma V. Espel, Elyssia Poggi Davis, Curt A. Sandman, Laura M. Glynn

Psychology Faculty Articles and Research

Objective: It is widely assumed that glucocorticoids represent a primary mechanism through which exposure to adversity and maternal psychological distress shape prenatal developmental trajectories of both mother and fetus. However, despite repeated investigations and the fact that prenatal cortisol has been reliably linked to developmental outcomes, the empirical evidence supporting an association between prenatal cortisol and maternal distress is scarce. In this study, a novel approach to assessing links between maternal prenatal psychological distress and gestational cortisol profiles, general growth mixture modeling (GGMM), was applied. Method: Measures of pregnancy anxiety, perceived stress, and state anxiety and depressive symptoms as well …

The Influence Of Unpredictable, Fragmented Parental Signals On The Developing Brain, Laura M. Glynn, Tallie Z. Baram

Psychology Faculty Articles and Research

Mental illnesses originate early in life, governed by environmental and genetic factors. Because parents are a dominant source of signals to the developing child, parental signals - beginning with maternal signals in utero - are primary contributors to children’s mental health. Existing literature on maternal signals has focused almost exclusively on their quality and valence (e.g. maternal depression, sensitivity). Here we identify a novel dimension of maternal signals: their patterns and especially their predictability/unpredictability, as an important determinant of children’s neurodevelopment. We find that unpredictable maternal mood and behavior presage risk for child and adolescent psychopathology. In experimental models, fragmented/unpredictable …

Prenatal Risk For Autism Spectrum Disorder (Asd): Fetal Cortisol Exposure Predicts Child Asd Symptoms, Sheena Ram, Mariann A. Howland, Curt A. Sandman, Elyssia Poggi Davis, Laura M. Glynn

Psychology Faculty Articles and Research

The etiology of autism spectrum disorder (ASD) is multifactorial, complex, and likely involves interactions among genetic, epigenetic, and environmental factors. With respect to environmental influences, a growing literature implicates intrauterine experiences in the origin of this pervasive developmental disorder. In this prospective longitudinal study, we examined the hypothesis that fetal exposure to maternal cortisol may confer ASD risk. In addition, because ASD is four times more prevalent in males than in females, and because sexually dimorphic responses to intrauterine experiences are commonly observed, we examined whether or not any associations differ by fetal sex. Maternal plasma cortisol was measured at …

Gestational Hormone Profiles Predict Human Maternal Behavior At 1-Year Postpartum, Laura M. Glynn, Elyssia Poggi Davis, Curt A. Sandman, Wendy A. Goldberg

Psychology Faculty Articles and Research

In many non-human species, including primates, gestational reproductive hormones play an essential role in the onset of maternal motivation and behaviors. We investigated the associations between prepartum estradiol and progesterone and maternal behavior at 1-year postpartum in 177 women. Blood was obtained at five gestational time points and an index of quality of maternal care was determined using a well-validated mother-child interaction protocol. Women who exhibited higher quality maternal care at 1-year postpartum were characterized by unique gestational profiles of estradiol, progesterone and the estrogen to progesterone ratio; specifically by slower accelerations and levels of these hormone trajectories beginning in …

Antenatal Glucocorticoid Treatment Is Associated With Diurnal Cortisol Regulation In Term-Born Children, M. N. Edelmann, Curt A. Sandman, Laura M. Glynn, D. A. Wing, Elyssia Poggi Davis

Psychology Faculty Articles and Research

Due to the rapid developmental changes that occur during the fetal period, prenatal influences can affect the developing central nervous system with lifelong consequences for physical and mental health. Glucocorticoids are one of the proposed mechanisms by which fetal programing occurs. Glucocorticoids pass through the blood-brain barrier and target receptors throughout the central nervous system. Unlike endogenous glucocorticoids, synthetic glucocorticoids readily pass through the placental barrier to reach the developing fetus. The synthetic glucocorticoid, betamethasone, is routinely given prenatally to mothers at risk for preterm delivery. Over 25% of the fetuses exposed to betamethasone will be born at term. Few …

Prenatal Maternal Stress Programs Infant Stress Regulation, Elyssia Poggi Davis, Laura M. Glynn, Feizal Waffarn, Curt A. Sandman

Psychology Faculty Articles and Research

Objective: Prenatal exposure to inappropriate levels of glucocorticoids (GCs) and maternal stress are putative mechanisms for the fetal programming of later health outcomes. The current investigation examined the influence of prenatal maternal cortisol and maternal psychosocial stress on infant physiological and behavioral responses to stress.

Methods: The study sample comprised 116 women and their full term infants. Maternal plasma cortisol and report of stress, anxiety and depression were assessed at 15, 19, 25, 31 and 36 + weeks' gestational age. Infant cortisol and behavioral responses to the painful stress of a heel-stick blood draw were evaluated at 24 hours after …

Development Of Fetal Movement Between 26 And 36 Weeks’ Gestation In Response To Vibroacoustic Stimulation, Marybeth Grant-Beuttler, Laura M. Glynn, Amy L. Salisbury, Elyssia Poggi Davis, Carol Holliday, Curt A. Sandman

Psychology Faculty Articles and Research

BACKGROUND: Ultrasound observation of fetal movement has documented general trends in motor development and fetal age when motor response to stimulation is observed. Evaluation of fetal movement quality, in addition to specific motor activity, may improve documentation of motor development and highlight specific motor responses to stimulation.

AIM: The aim of this investigation was to assess fetal movement at 26 and 36-weeks gestation during three conditions (baseline, immediate response to vibro-acoustic stimulation (VAS), and post-response).

DESIGN: A prospective, longitudinal design was utilized.

SUBJECTS: Twelve normally developing fetuses, eight females and four males, were examined with continuous ultrasound imaging.

OUTCOME MEASURES: …
