Maternal Prenatal Cortisol Trajectories Predict Accelerated Growth In Infancy, Jennifer Hahn-Holbrook, Elysia Poggi Davis, Curt A. Sandman, Laura M. Glynn

Psychology Faculty Articles and Research

Higher maternal cortisol in pregnancy has been linked to childhood obesity. Much of the previous research has been limited in that cortisol in pregnancy is only measured at one time-point, precluding the ability to examine critical timing effects of prenatal maternal cortisol. To fill this gap, this longitudinal study measured maternal plasma cortisol at 15, 19, 25, and 31 weeks of pregnancy, and assessed infant body mass index percentile (BMIP)1 at birth, 3, 6, 12, and 24 months in 189 mother-infant pairs. Three distinct patterns of maternal cortisol in pregnancy (typical, steep, and flat trajectories) were identified using general growth …

Early Life Exposure To Unpredictable Parental Sensory Signals Shapes Cognitive Development Across Three Species, Elyssia Poggi Davis, Kari Mccormack, Hina Arora, Desiree Sharpe, Annabel K. Short, Jocelyne Bachevalier, Laura M. Glynn, Curt A. Sandman, Hal S. Stern, Mar Sanchez, Tallie Z. Baram

Psychology Faculty Articles and Research

Exposure to early life adversity has long term consequences on cognitive function. Most research has focused on understanding components of early life adversities that contribute to later risk, including poverty, trauma, maltreatment, and neglect. Whereas these factors, in the aggregate, explain a significant proportion of emotional and cognitive problems, there are serious gaps in our ability to identify potential mechanisms by which early life adversities might promote vulnerability or resilience. Here we discuss early life exposure to unpredictable signals from the caretaker as an understudied type of adversity that is amenable to prevention and intervention. We employ a translational approach …

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 Exposure To Maternal Psychological Distress And Telomere Length In Childhood, Stephanie A. Stout-Oswald, Laura M. Glynn, Marco Bisoffi, Catherine H. Demers, Elysia Poggi Davis

Psychology Faculty Articles and Research

Telomere length (TL) is a biological marker of cellular aging, and shorter TL in adulthood is associated with increased morbidity and mortality risk. It is likely that these differences in TL are established long before adulthood, and there is growing evidence that TL can reflect prenatal experiences. Although maternal prenatal distress predicts newborn TL, it is unknown whether the relation between prenatal exposure to maternal distress and child TL persists through childhood. The purpose of the current longitudinal, prospective study is to examine the relation between prenatal exposure to maternal distress (perceived stress, depressive symptoms, pregnancy-related anxiety) and TL in …

The Contribution Of Racism-Related Stress And Adversity To Disparities In Birth Outcomes: Evidence And Research Recommendations, Sabrina R. Liu, Laura M. Glynn

Psychology Faculty Articles and Research

Currently, racial and ethnic differences in adverse birth outcomes and infant mortality are some of the largest and most persistent health disparities in the United States. This narrative review article synthesizes existing literature to present a conceptual model of how racism-related stress and adversity are critical determinants of such disparities. We describe how historical and ongoing racism has created conditions wherein women of color are disproportionately exposed to chronic, multilayered stress and adversity and how the biological consequences of exposure to these stressors confers risk for adverse birth outcomes. Next, we identify important priorities and considerations for future research, including …

Prenatal Diagnosis Of Maternal Serum From Mothers Carrying Β-Thalassemic Fetus, Yumna Fazal, Muhammad Zohaib, Basir Syed, Saqib H. Ansari, Zehra Hashim, Aftab Ahmed, Shamshad Zarina

Pharmacy Faculty Articles and Research

Background

Current study focused on discovering protein biomarkers from the maternal serum of β-thalassemic trait mothers carrying the normal fetus and β-thalassemic major fetus.

Method

Serum samples from β-thalassemic trait mothers carrying major (N=5) and normal fetuses (N=5) were studied. IVS1-5 thalassemia mutation was common among β-thalassemic trait mothers who were carrying homozygous β-thalassemic fetus (IVS1-5/ IVS1-5 mutation) or normal fetus (no mutation). We employed two-dimensional gel electrophoresis and mass spectrometric analysis to explore differentially expressed maternal serum proteins from thalassemia carrier couples having the same β-thalassemia mutation. Western blotting was performed for one of the identified proteins to validate …

Development Of The Infant Gut Microbiome Predicts Temperament Across The First Year Of Life, Molly Fox, S. Melanie Lee, Kyle S. Wiley, Venu Lagishetty, Curt A. Sandman, Jonathan P. Jacobs, Laura M. Glynn

Psychology Faculty Articles and Research

Perturbations to the gut microbiome are implicated in altered neurodevelopmental trajectories that may shape life span risk for emotion dysregulation and affective disorders. However, the sensitive periods during which the microbiome may influence neurodevelopment remain understudied. We investigated relationships between gut microbiome composition across infancy and temperament at 12 months of age. In 67 infants, we examined if gut microbiome composition assessed at 1–3 weeks, 2, 6, and 12 months of age was associated with temperament at age 12 months. Stool samples were sequenced using the 16S Illumina MiSeq platform. Temperament was assessed using the Infant Behavior Questionnaire-Revised (IBQ-R). Beta …

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 …

Aberrant Maturation Of The Uncinate Fasciculus Follows Exposure To Unpredictable Patterns Of Maternal Signals, Steven J. Granger, Laura M. Glynn, Curt A. Sandman, Steven L. Small, Andre Obenaus, David B. Keator, Tallie Z. Baram, Hal S. Stern, Michael A. Yassa, Elyssia Poggi Davis

Psychology Faculty Articles and Research

Across species, unpredictable patterns of maternal behavior are emerging as novel predictors of aberrant cognitive and emotional outcomes later in life. In animal models, exposure to unpredictable patterns of maternal behavior alters brain circuit maturation and cognitive and emotional outcomes. However, whether exposure to such signals in humans alters the development of brain pathways is unknown. In mother–child dyads, we tested the hypothesis that exposure to more unpredictable maternal signals in infancy is associated with aberrant maturation of corticolimbic pathways. We focused on the uncinate fasciculus, the primary fiber bundle connecting the amygdala to the orbitofrontal cortex and a key …

Child Obesity Moderates The Association Between Poverty And Academic Achievement, Ashley W. Kranjac, Dinko Kranjac

Sociology Faculty Articles and Research

Childhood overweight and obesity are major public health problems in the United States. Children who experience poverty are 1.5 times more likely to suffer with overweight and 1.6 times more likely to have obesity. The extent to which overweight or obesity exacerbates the negative influence of socioeconomic inequality on child academic outcomes has not yet been examined. We estimated the effect of poverty on math and reading achievement trajectories using the Early Childhood Longitudinal Study (ECLS) Kindergarten class of 1998−1999 survey data and multilevel growth curve modeling techniques. Our findings indicate that the impact of obesity status is more pronounced …

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 …

Maternal Prenatal Cortisol Programs The Infant Hypothalamic–Pituitary–Adrenal Axis, Jessica L. Irwin, Amy L. Meyering, Gage Peterson, Laura M. Glynn, Curt A. Sandman, Laurel M. Hicks, Elysia Poggi Davis

Psychology Faculty Articles and Research

One of the key proposed agents of fetal programming is exposure to maternal glucocorticoids. Experimental animal studies provide evidence that prenatal exposure to elevated maternal glucocorticoids has consequences for hypothalamic–pituitary–adrenal (HPA) axis functioning in the offspring. There are very few direct tests of maternal glucocorticoids, such as cortisol, during human pregnancy and associations with infant cortisol reactivity. The current study examined the link between maternal prenatal cortisol trajectories and infant cortisol reactivity to the pain of inoculation in a sample of 152 mother-infant (47.4% girls) pairs. The results from the current study provide insight into fetal programming of the 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 …

Cesarean Delivery And Infant Cortisol Regulation, Leticia D. Martinez, Laura M. Glynn, Curt A. Sandman, Deborah A. Wing, Elysia Poggi Davis

Psychology Faculty Articles and Research

Background:
Cesarean delivery reduces the risk of infant and maternal morbidity and mortality when medically indicated, however, the cesarean delivery rate is estimated to be two to three times higher than medically necessary. The World Health Organization and American College of Obstetricians and Gynecologists have expressed concern over the high rates of cesarean delivery, citing evidence that cesarean delivery has negative short- and long-term consequences for the health of the infant, mother, and for future pregnancies. Infants delivered by cesarean are at an increased risk of metabolic disease and immune dysfunction throughout the lifespan. Preliminary research suggests that the …

Fertility Awareness And Parenting Intentions Among Mexican Undergraduate And Graduate University Students, J. M. Place, Brennan D. Peterson, B. Horton, M. Sanchez

Marriage and Family Therapy Faculty Articles and Research

An online, cross-sectional survey was carried out between November 2017 and January 2018 to assess fertility awareness among students attending the National Autonomous University of Mexico (UNAM) in Mexico City. A total of 371 students participated in the survey (n = 228 females, 143 males). 75% of females and 74% of males believed a woman’s fertility begins to decline markedly after age 40. Over 75% of all participants overestimated the probability of couples having a live birth after undergoing one cycle of IVF. With regard to parenting intentions, only 48% of females wished to have children compared to 59% …

Immune Function During Pregnancy Varies Between Ecologically Distinct Populations, Carmen Hové, Benjamin C. Trumble, Amy S. Anderson, Jonathan Stieglitz, Hillard Kaplan, Michael Gurven, Aaron Blackwell

ESI Publications

Background and objectives

Among placental mammals, females undergo immunological shifts during pregnancy to accommodate the fetus (i.e. fetal tolerance). Fetal tolerance has primarily been characterized within post-industrial populations experiencing evolutionarily novel conditions (e.g. reduced pathogen exposure), which may shape maternal response to fetal antigens. This study investigates how ecological conditions affect maternal immune status during pregnancy by comparing the direction and magnitude of immunological changes associated with each trimester among the Tsimane (a subsistence population subjected to high pathogen load) and women in the USA.

Methodology

Data from the Tsimane Health and Life History Project (N = 935) and …

Mode Of Delivery And Infant Cognitive Development, Madison Olson, Laura M. Glynn

Student Scholar Symposium Abstracts and Posters

The rate of nonindicated cesarean births is increasing each year within the United States. Although cesarean delivery can function as a life- saving intervention, emerging evidence suggests that it may also be associated with deleterious developmental consequences for the child. Here we test the hypothesis that mode of delivery is associated with cognitive development during infancy. 229 pregnant women were recruited and their infants’ cognitive development was assessed at 6, 12 and 24 months with the Bayley Scales of Infant Development. Medical charts were reviewed by obstetric nurses to determine prenatal medical risk and birth outcomes, including mode of delivery. …

Maternal Depressive Symptoms Predict General Liability In Child Psychopathology, Danielle A. Swales, Hannah R. Snyder, Benjamin L. Hankin, Curt A. Sandman, Laura M. Glynn, Elyssia Poggi Davis

Psychology Faculty Articles and Research

Objective: The current study examines how maternal depressive symptoms relate to child psychopathology when structured via the latent bifactor model of psychopathology, a new organizational structure of psychopathological symptoms consisting of a general common psychopathology factor (p-factor) and internalizing- and externalizing-specific risk.

Method: Maternal report of depressive symptoms (Beck Depression Inventory – II) and child psychopathological symptoms (Child Behavior Checklist and Children’s Behavior Questionnaire) were provided by 554 mother-child pairs. Children in the sample were 7.7 years old on average (SD = 1.35, range = 5–11 years), and were 49.8% female, 46% Latinx, and 67% …

Characterization Of Extracellular Vesicles Isolated From Human Milk Using A Precipitation-Based Method, Diana C. Bickmore, John Miklavcic

Food Science Faculty Articles and Research

Extracellular vesicles (EV) function in intercellular communication, and those in human milk may confer immunologic benefits to infants. Methods of EV isolation such as ultracentrifugation (UC) may not be feasible for the study of EVs in human milk due to the need for large sample volume. A technique to isolate EVs from a small volume of human milk using a precipitation reagent is described herein. Electron microscopy, nanoparticle tracking analysis, and semi-quantitative antibody array were conducted to confirm isolation of human milk EVs. Count, size, protein content, and fatty acid quantification of EVs were determined. This isolation technique yielded 8.9 …

Unpredictable Maternal Behavior Is Associated With A Blunted Infant Cortisol Response, Amanda N. Noroña-Zhou, Alyssa Morgan, Laura M. Glynn, Curt A. Sandman, Tallie Z. Baram, Hal S. Stern, Elyssia Poggi Davis

Psychology Faculty Articles and Research

Background

Dysregulation of the hypothalamic-pituitary-adrenal (HPA) axis is associated with poor physical and mental health. Early-life adversity may dysregulate cortisol response to subsequent stress. This study examines the association between patterns of maternal behavior and infant stress response to a challenge. Specifically, we test whether infant exposure to unpredictable maternal sensory signals is related to the cortisol response to a painful stressor.

Method

Participants were 102 mothers and their children enrolled in a longitudinal study. Patterns of maternal sensory signals were evaluated at 6 and 12 months during a 10-min mother–infant play episode. Entropy rate was calculated as a quantitative …

Insights Into Novel Infant Milk Formula Bioactives, Jordan Skolnick, Claire Chou, John Miklavcic

Food Science Faculty Articles and Research

Human milk provides optimal infant nutrition for early life development. However, there are situations in which human milk feeding is not the most viable option for infant nutrition. Some factors include maternal illness, lactation insufficiency, storage complications, and time constraints. As a result, modern infant formula has become a substitute or alternative when breastfeeding is not possible or is inadequate for infants. In the optimal design of formula, many factors are considered in creating a product that is safe and provides a nutritional profile either equivalent to human milk or in optimal alignment with infant needs. Human milk composition serves …

Human Milk Omega-3 Fatty Acid Composition Is Associated With Infant Temperament, Jennifer Hahn-Holbrook, Adi Fish, Laura M. Glynn

Psychology Faculty Articles and Research

There is growing evidence that omega-3 (n-3) polyunsaturated fatty-acids (PUFAs) are important for the brain development in childhood and are necessary for an optimal health in adults. However, there have been no studies examining how the n-3 PUFA composition of human milk influences infant behavior or temperament. To fill this knowledge gap, 52 breastfeeding mothers provided milk samples at 3 months postpartum and completed the Infant Behavior Questionnaire (IBQ-R), a widely used parent-report measure of infant temperament. Milk was assessed for n-3 PUFAs and omega-6 (n-6) PUFAs using gas-liquid chromatography. The total fat and the ratio of n6/n-3 fatty acids …

Decomposing Trends In Child Obesity, Ashley Wendell Kranjac, Robert L. Wagmiller

Sociology Faculty Articles and Research

We unravel the absolute level and relative prominence of two demographic processes that are relevant for childhood obesity, and that will ultimately determine the long-term course and pace of change in child obesity rates. We leverage data from the National Health and Nutrition Examination Survey to decompose change in child obesity from 1971 to 2012. We partition change into that attributable to (1) healthier, more nutritionally and economically advantaged cohorts in the population being replaced by cohorts of children who are less advantaged (between-cohort change), and (2) the health habits, nutrition, and social and economic circumstances of all cohorts of …

Across Continents And Demographics, Unpredictable Maternal Signals Are Associated With Children's Cognitive Function, Elyssia Poggi Davis, Riikka Korja, Linnea Karlsson, Laura Glynn, Curt A. Sandman, Brian Vegetabile, Eeva-Leena Kataja, Saara Nolvi, Eija Sinervä, Juho Pelto, Hasse Karlsson, Hal S. Stern, Tallie Z. Baram

Psychology Faculty Articles and Research

Background

Early life experiences have persisting influence on brain function throughout life. Maternal signals constitute a primary source of early life experiences, and their quantity and quality during sensitive developmental periods exert enduring effects on cognitive function and emotional and social behaviors. Here we examined if, in addition to established qualitative dimensions of maternal behavior during her interactions with her infant and child, patterns of maternal signals may contribute to the maturation of children's executive functions. We focused primarily on effortful control, a potent predictor of mental health outcomes later in life.

Methods

In two independent prospective cohorts in Turku, …

Changing Healthcare Provider And Parent Behaviors In The Pediatric Post‐Anesthesia‐Care‐Unit To Reduce Child Pain: Nurse And Parent Training In Postoperative Stress (Np‐Tips), Brooke N. Jenkins, Michelle Fortier, Robert S. Stevenson, Mai Makhlouf, Paulina Lim, Remy Converse, Zeev N. Kain

Psychology Faculty Articles and Research

Background

Children who undergo surgery experience significant pain in the post anesthesia care unit. Nurse and parent behaviors in the post anesthesia care unit directly impact child postoperative pain. Therefore, we have developed and evaluated (Phase 1) and then tested (Phase 2) the feasibility of a new intervention (Nurse and Parent Training in Postoperative Stress) to alter parent and nurse behaviors in a way consistent with reducing child postoperative pain.

Methods

In Phase 1, a multidisciplinary team of experts (physicians, nurses, and psychologists) developed an empirically‐based intervention which was then evaluated by experienced nurses (N = 8) and parents …

Oxytocin Receptor Gene (Oxtr) And Father Support Interact To Predict Depressive Symptoms Postpartum, Parambir Bhatti, Taylor Delaney, Michael Poulin, Jennifer Hahn-Holbrook

Psychology Faculty Articles and Research

Postpartum depression (PPD) is a debilitating mental illness affecting approximately 13% of mothers after birth. Both genetic and psychosocial factors contribute to PPD risk, but very little is known about how these factors interact. We tested whether the rs53576 polymorphism in the oxytocin receptor (OXTR) gene accounts for variation in the impact of low social support as a risk factor for depression among mothers during the perinatal period. New mothers (N = 220) provided saliva or blood DNA samples and completed surveys assessing PPD symptoms and perceived social support. In a significant interaction, social support from the …

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 …
