Individual Longitudinal Changes In Dna-Methylome Identify Signatures Of Early-Life Adversity And Correlate With Later Outcome, Annabel K. Short, Ryan Weber, Noriko Kamei, Christina Wilcox Thai, Hina Arora, Ali Mortazavi, Hal S. Stern, Laura M. Glynn, Tallie Z. Baram

Psychology Faculty Articles and Research

Adverse early-life experiences (ELA) affect a majority of the world's children. Whereas the enduring impact of ELA on cognitive and emotional health is established, there are no tools to predict vulnerability to ELA consequences in an individual child. Epigenetic markers including peripheral-cell DNA-methylation profiles may encode ELA and provide predictive outcome markers, yet the interindividual variance of the human genome and rapid changes in DNA methylation in childhood pose significant challenges. Hoping to mitigate these challenges we examined the relation of several ELA dimensions to DNA methylation changes and outcome using a within-subject longitudinal design and a high methylation-change threshold. …

Dhea: A Neglected Biological Signal That May Affect Fetal And Child Development, Natasha A. Bailey, Elysia Poggi Davis, Curt A. Sandman, Laura M. Glynn

Psychology Faculty Articles and Research

The stress-sensitive maternal hypothalamic–pituitary–adrenal (HPA) axis through the end-product cortisol, represents a primary pathway through which maternal experience shapes fetal development with long-term consequences for child neurodevelopment. However, there is another HPA axis end-product that has been widely ignored in the study of human pregnancy. The synthesis and release of dehydroepiandosterone (DHEA) is similar to cortisol, so it is a plausible, but neglected, biological signal that may influence fetal neurodevelopment. DHEA also may interact with cortisol to determine developmental outcomes. Surprisingly, there is virtually nothing known about human fetal exposure to prenatal maternal DHEA and offspring neurodevelopment. The current study …

One Size Doesn’T Fit All: Attitudes Towards Work Modify The Relation Between Parental Leave Length And Postpartum Depression, Christine Y. Chang, Sabrina R. Liu, Laura M. Glynn

Psychology Faculty Articles and Research

The present study aimed to investigate the relationship between parental leave length and maternal depressive symptoms at six- and twelve-months postpartum and whether this relation was influenced by women’s attitudes towards leave, whether leave was paid or unpaid, and the reason they returned to work. The sample included 115 working women recruited during pregnancy as part of a larger longitudinal study. Analyses revealed that maternal attitudes toward leave influenced the association between leave length and depressive symptoms. Specifically, longer leaves were associated with increased depressive symptoms for women who missed their previous activities at work. Furthermore, women who missed work …

Experiences Of Covid-19-Related Racism And Impact On Depression Trajectories Among Racially/Ethnically Minoritized Adolescents, Sabrina R. Liu, Elysia Poggi Davis, Anton M. Palma, Hal S. Stern, Curt A. Sandman, Laura M. Glynn

Psychology Faculty Articles and Research

Purpose

In 2020, racially/ethnically minoritized (REMD) youth faced the “dual pandemics” of COVID-19 and racism, both significant stressors with potential for adverse mental health effects. The current study tested whether short- and long-term trajectories of depressive symptoms from before to during the COVID-19 pandemic differed between REMD adolescents who did and did not endorse exposure to COVID-19-era-related racism (i.e., racism stemming from conditions created or exacerbated by the COVID-19 pandemic).

Methods

A community sample of 100 REMD adolescents enrolled in an ongoing longitudinal study of mental health was assessed before and during the COVID-19 pandemic. Participants were 51% girls, mean …

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 …

Most were from the United States (n = 22) and cross-sectional (n = 33), and nearly all evaluated associations among adults. Among studies conducted in LMICs, nearly all were from middle-income countries and only one was carried out in low-income country. Education (n = …

Obesogenic Environments And Cardiovascular Disease: A Path Analysis Using Us Nationally Representative Data, Fangqi Guo, Georgiana Bostean, Vincent Berardi, Alfredo J. Velasquez, Jennifer W. Robinette

Psychology Faculty Articles and Research

Introduction

People living in obesogenic environments, with limited access to healthful food outlets and exercise facilities, generally have poor health. Previous research suggests that behavioral risk factors and indicators of physiological functioning may mediate this link; however, no studies to date have had the requisite data to investigate multi-level behavioral and physiological risk factors simultaneously. The present study conducted serial and parallel mediation analyses to examine behavioral and physiological pathways explaining the association between environmental obesogenicity and cardiovascular disease (CVD).

Methods

This cross-sectional observational study used data from the 2012–2016 Health and Retirement Study, a representative survey of US older …

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 …

The Acute And Persisting Impact Of Covid-19 On Trajectories Of Adolescent Depression: Sex Differences And Social Connectedness, Sabrina R. Liu, Elyssia Poggi Davis, Anton M. Palma, Curt A. Sandman, Laura M. Glynn

Psychology Faculty Articles and Research

Background

The COVID-19 era is a time of unprecedented stress, and there is widespread concern regarding its short- and long-term mental health impact. Adolescence is a sensitive period for the emergence of latent psychopathology vulnerabilities, often activated by environmental stressors. The present study examined COVID-19′s impact on adolescent depression and possible influences of different domains of social connectedness (loneliness, social media use, social video game time, degree of social activity participation).

Methods

A community sample of 175 adolescents (51% boys, mean age = 16.01 years) completed questionnaires once before and twice during the COVID-19 pandemic. Piecewise growth modeling examined the …

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 …

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 …

A Predictable Home Environment May Protect Child Mental Health During The Covid-19 Pandemic, Laura M. Glynn, Elyssia Poggi Davis, Joan L. Luby, Tallie Z. Baram, Curt A. Sandman

Psychology Faculty Articles and Research

Objective

Information about the adverse effects of the COVID-19 pandemic on adolescent and adult mental health is growing, yet the impacts on preschool children are only emerging. Importantly, environmental factors that augment or protect from the multidimensional and stressful influences of the pandemic on emotional development of young children are poorly understood.

Methods

Depressive symptoms in 169 preschool children (mean age 4.1 years) were assessed with the Preschool Feelings Checklist during a state-wide stay-at-home order in Southern California. Mothers (46% Latinx) also reported on externalizing behaviors with the Strengths & Difficulties Questionnaire. To assess the role of environmental factors in …

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 …

Psychology Faculty Articles and Research

Background

This study examined the association between race/ethnicity and health insurance payer type with pediatric opioid and non-opioid ordering in an inpatient hospital setting.

Methods

Cross-sectional inpatient encounter data from June 2013 to June 2018 was retrieved from a pediatric children’s hospital in Southern California (N = 55,944), and statistical analyses were performed to determine associations with opioid ordering.

Results

There was a significant main effect of race/ethnicity on opioid and non-opioid orders. Physicians ordered significantly fewer opioid medications, but a greater number of non-opioid medications, for non-Hispanic African American children than non-Hispanic Asian, Hispanic/Latinx, and non-Hispanic White pediatric …

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% …

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 …

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 …

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, …

Objective: To parameterize and validate two existing algorithms for identifying out-of-bed time using 24-hour hip-worn accelerometer data from older women. Approach: Overall, 628 women (80±6 years old) wore ActiGraph GT3X+ accelerometers 24 hours/day for up to 7 days and concurrently completed sleep-logs. Trained staff used a validated visual analysis protocol to measure in-bed periods on accelerometer tracings (criterion). The Tracy and McVeigh algorithms were adapted for optimal use in older adults. A training set of 314 women was used to choose two key thresholds by maximizing the sum of sensitivity and specificity for each algorithm and data (vertical axis, VA, …

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 …

Delay Discount Rate Moderates A Physical Activity Intervention Testing Immediate Rewards, Christine B. Phillips, Jane C. Hurley, Siddhartha S. Angadi, Michael Todd, Vincent Berardi, Melbourne Hovell, Marc A. Adams

Psychology Faculty Articles and Research

Financial incentives can increase physical activity (PA), but differences in the immediacy of reward delivery and individual differences in delay discount rates (i.e., higher discount values associated with less tolerance for delayed rewards) may explain differential responding. The current study tested whether delay discount rate moderated the relative effectiveness of immediate financial rewards on increasing daily PA. Inactive, overweight adults (ages 18–60, N = 96) were randomized to receive either smaller, immediate goal-contingent rewards or larger, delayed rewards for participation. Delay discount rates were derived for those who completed the Monetary Choice Questionnaire (N = 85). Linear mixed models tested …

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 …

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 …

Measuring Novel Antecedents Of Mental Illness: The Questionnaire Of Unpredictability In Childhood, Laura M. Glynn, Hal S. Stern, Mariann A. Howland, Victoria B. Risbrough, Dewleen G. Baker, Caroline M. Nievergelt, Tallie Z. Baram, Elysia P. Davis

Psychology Faculty Articles and Research

Increasing evidence indicates that, in addition to poverty, maternal depression, and other well-established factors, unpredictability of maternal and environmental signals early in life influences trajectories of brain development, determining risk for subsequent mental illness. However, whereas most risk factors for later vulnerability to mental illness are readily measured using existing, clinically available tools, there are no similar measures for assessing early-life unpredictability. Here we validate the Questionnaire of Unpredictability in Childhood (QUIC) and examine its associations with mental health in the context of other indicators of childhood adversity (e.g., traumatic life events, socioeconomic status, and parenting quality). The QUIC was …

Pregnancy Anxiety Predicts Shorter Gestation In Latina And Non-Latina White Women: The Role Of Placental Corticotrophin-Releasing Hormone, Isabel F. Ramos, Christine M. Guardino, Maxwell Mansolf, Laura M. Glynn, Curt A. Sandman, Calvin J. Hobel, Christine Dunkel Schetter

Psychology Faculty Articles and Research

Objective

Previous research has shown that a woman’s anxiety about her pregnancy predicts gestational length. Placental corticotrophin-releasing hormone (CRH) is a stress-responsive peptide proposed as a mechanism. We examined placental CRH as a physiological mediator of the association between pregnancy anxiety and gestational length in Latina and non-Latina White women to replicate evidence of associations between pregnancy anxiety, placental CRH and gestational length; to test whether placental CRH levels or changes mediate effects of pregnancy anxiety on gestational length; to examine ethnic differences in pregnancy anxiety, placental CRH, and gestational length; and to explore whether the effects of pregnancy anxiety …

Prompts To Increase Physical Activity At Points-Of-Choice Between Stairs And Escalators: What About Escalator Climbers?, John Belletierre, Ben Nguyen, Sandy Liles, Vincent Berardi, Marc A. Adams, Paddy Dempsey, Yael Benporat, Jacqueline Kerr, Andrea Z. Lacroix, Melbourne Hovell

Psychology Faculty Articles and Research

Since 1980, many studies have evaluated whether stair-use prompts increased physical activity by quantifying changes in stair use. To more completely evaluate changes in physical activity, this study addressed the often-overlooked assessment of climbing up escalators by evaluating the degree to which stair-use sign prompts increased active ascent—defined as stair use or escalator climbing. Over 5 months, at an airport stairs/escalator point of choice, we video-recorded passersby (N = 13,544) who ascended either stairs or escalators, on 10 days with signs and 10 days without signs. Ascenders using the stairs, standing on the escalator, and climbing the escalator were …

Maternal Programming: Application Of A Developmental Psychopathology Perspective, Laura M. Glynn, Mariann A. Howland, Molly Fox

Psychology Faculty Articles and Research

The fetal phase of life has long been recognized as a sensitive period of development. Here we posit that pregnancy represents a simultaneous sensitive period for the adult female with broad and persisting consequences for her health and development, including risk for psychopathology. In this review, we examine the transition to motherhood through the lens of developmental psychopathology. Specifically, we summarize the typical and atypical changes in brain and behavior that characterize the perinatal period. We highlight how the exceptional neuroplasticity exhibited by women during this life phase may account for increased vulnerability for psychopathology. Further, we discuss several modes …
