Affect Regulation And Allostatic Load Over Time, Amanda E. Ng, Tara Gruenewald, Robert-Paul Juster, Claudia Trudel-Fitzgerald Aug 2024

Affect Regulation And Allostatic Load Over Time, Amanda E. Ng, Tara Gruenewald, Robert-Paul Juster, Claudia Trudel-Fitzgerald

Psychology Faculty Articles and Research

Objective

Emerging work suggests that affect regulation strategies (e.g., active coping, anger expression) predict disease and mortality risk, with sometimes divergent estimates by sex or education levels. However, few studies have examined potential underlying biological mechanisms. This study assessed the longitudinal association of affect regulation with future allostatic load.

Method

In 2004–2006, 574 participants from the Midlife in the United States study completed validated scales assessing use of nine general and emotion-specific regulatory strategies (e.g., denial, anger expression). As a proxy for how flexibly participants regulate their affect, variability in the use of regulatory strategies was operationalized using a standard …

Neighborhood Socioeconomic Context Predicts Pediatric Asthma Exacerbation, Ashley W. Kranjac, Zeev N. Kain, Louis Ehwerhemuepha, Michael Weiss, Brooke N. Jenkins Jul 2024

Neighborhood Socioeconomic Context Predicts Pediatric Asthma Exacerbation, Ashley W. Kranjac, Zeev N. Kain, Louis Ehwerhemuepha, Michael Weiss, Brooke N. Jenkins

Sociology Faculty Articles and Research

Causes of asthma exacerbation in children have been studied extensively at the individual level, but contributions of neighborhood-level factors are less explored. We test which distinctive residential characteristics produce variation in uncontrolled asthma among pediatric patients. We extracted electronic medical record data from pediatric patients living in Southern California and used multilevel modeling techniques to isolate which neighborhood characteristics drive inequitable asthma control. Above and beyond the individual-level factors known to predict inadequate disease control, neighborhoods with greater concentration of non-Hispanic black residents (odds ratios [OR] = 1.02; 95% confidence interval [CI]: 0.99-1.03; P < .05), higher proportions of female-headed households (OR = 1.01; 95% CI: 0.99-1.01; P < .05), and higher levels of ambient air pollution (OR = 1.05; 95% CI: 1.01-1.10; P < .001) associate with greater odds of asthma exacerbation. The interplay between community characteristics and asthma management during childhood is complex, and place-based initiatives are needed to narrow the gap in asthma exacerbation.

The Role Of Positive Affect In Asthma Control And Symptom Severity In Adolescents, Brooke N. Jenkins, Logan T. Martin, Jill S. Halterman, Judith T. Moskowitz, Laura M. Glynn, Pornchai Tirakitsoontorn, Sunil Kamath, Zeev N. Kain

Psychology Faculty Articles and Research

Introduction

We test the effects of positive affect and its arousal subscale components of calm, wellbeing, and vigor on asthma control and symptom severity in adolescents with moderate to severe asthma. Additionally, we test whether positive affect (and its arousal components) moderate how stress impacts asthma control and symptom severity.

Methods

Adolescents with asthma (N = 66, ages 12–17) completed brief surveys 4 times a day for 7 days reporting on their positive affect, stress, and asthma symptom severity and conducted a morning peak expiratory flow assessment each day. Asthma control and psychological asthma triggers were assessed at the …

Mean Affect Moderates The Association Between Affect Variability And Mental Health, Brooke N. Jenkins, Lydia Q. Ong, Anthony D. Ong, Hee Youn (Helen) Lee, Julia K. Boehm

Psychology Faculty Articles and Research

Increasing evidence suggests that within-person variation in affect is a dimension distinct from mean levels along which individuals can be characterized. This study investigated affect variability’s association with concurrent and longitudinal mental health and how mean affect levels moderate these associations. The mental health outcomes of depression, panic disorder, self-rated mental health, and mental health professional visits from the second and third waves of the Midlife in the United States Study were used for cross-sectional (n = 1,676) and longitudinal outcomes (n = 1,271), respectively. These participants took part in the National Study of Daily Experiences (NSDE II), …


Pediatric Obesity In The United States: Age–Period–Cohort Analysis, Ashley W. Kranjac, Dinko Kranjac, Roxanne I. Aguilera Jun 2024

Pediatric Obesity In The United States: Age–Period–Cohort Analysis, Ashley W. Kranjac, Dinko Kranjac, Roxanne I. Aguilera

Sociology Faculty Articles and Research

The rates of obesity among American children aged 2–5 years has reached a historic high. It is crucial to identify the putative sources of population-level increases in obesity prevalence among preschool-aged children because early childhood is a critical window for obesity prevention and thus reduction of future incidence. We used the National Health and Nutrition Examination Survey data and hierarchical age–period–cohort analysis to examine lifecycle (i.e., age), historical (i.e., period), and generational (i.e., cohort) distribution of age- and sex-specific body mass index z-scores (zBMI) among 2–5-year-olds in the U.S. from 1999 to 2018. Our current findings indicate that period effects, …

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. …

Sufferance For Snuff Puffs: The Acceptability And Behavior Of Smoking Marijuana And Tobacco Inside The House, Eusabeia Silfanus, Oliver Lopez, Vincent Berardi

Student Scholar Symposium Abstracts and Posters

Secondhand smoke (SHS) released from indoor smoking contributes to household air pollution, releasing large quantities of fine particulate matter which can pose negative health outcomes, especially for developing children who spend most of their time at home. The increased legalization of marijuana increases its recreational and medicinal use along with its acceptability. With tobacco use remaining prevalent, the use of marijuana and/or tobacco remains common and may occur inside the home. Project Fresh Air conducted in San Diego County studies the air quality in households (n = 298) with at least one adult smoking tobacco and/or marijuana living with at …

Adolescent Marijuana Use And The Contribution To The Development Of Schizophrenia, Jocelyn Spandikow Apr 2024

Adolescent Marijuana Use And The Contribution To The Development Of Schizophrenia, Jocelyn Spandikow

Psychology Student Papers and Posters

Schizophrenia is an often debilitating mental condition that has become a popular topic of psychological research in recent years. Current research examines the correlation between drug use, genetics, and environment on the development of schizophrenia. Research looks at the structure of the brain in individuals with and without schizophrenia. However, research has failed to look at the specific correlation between marijuana use in adolescent youth and the developmental impact on the brain, including in the development of schizophrenia. The legalization of many recreational drugs, including marijuana, has come to fruition in recent years. This has raised concerns over adolescent access …

INTRODUCTION

We address the extent to which adolescent cognition predicts dementia risk in later life, mediated by educational attainment and occupational complexity.

METHODS

Using data from Project Talent Aging Study (PTAS), we fitted two structural equation models to test whether adolescent cognition predicts cognitive impairment (CI) and Ascertain Dementia 8 (AD8) status simultaneously (NCognitive Assessment = 2477) and AD8 alone (NQuestionnaire = 6491) 60 years later, mediated by education and occupational complexity. Co-twin control analysis examined 82 discordant pairs for CI/AD8.

RESULTS

Education partially mediated the effect of adolescent cognition on CI in the cognitive assessment aample and …


Annual Research Review: The Power Of Predictability – Patterns Of Signals In Early Life Shape Neurodevelopment And Mental Health Trajectories, Elysia Poggi Davis, Laura M. Glynn Feb 2024

Annual Research Review: The Power Of Predictability – Patterns Of Signals In Early Life Shape Neurodevelopment And Mental Health Trajectories, Elysia Poggi Davis, Laura M. Glynn

Psychology Faculty Articles and Research

The global burden of early life adversity (ELA) is profound. The World Health Organization has estimated that ELA accounts for almost 30% of all psychiatric cases. Yet, our ability to identify which individuals exposed to ELA will develop mental illness remains poor and there is a critical need to identify underlying pathways and mechanisms. This review proposes unpredictability as an understudied aspect of ELA that is tractable and presents a conceptual model that includes biologically plausible mechanistic pathways by which unpredictability impacts the developing brain. The model is supported by a synthesis of published and new data illustrating the significant …


Temporal Relation Between Pubertal Development And Peer Victimization In A Prospective Sample Of Us Adolescents, Jessica A. Marino, Elysia Poggi Davis, Laura M. Glynn, Curt A. Sandman, Jennifer Hahn-Holbrook Feb 2024

Temporal Relation Between Pubertal Development And Peer Victimization In A Prospective Sample Of Us Adolescents, Jessica A. Marino, Elysia Poggi Davis, Laura M. Glynn, Curt A. Sandman, Jennifer Hahn-Holbrook

Psychology Faculty Articles and Research

Peer victimization typically peaks in early adolescence, leading researchers to hypothesize that pubertal timing is a meaningful predictor of peer victimization. However, previous methodological approaches have limited our ability to parse out which puberty cues are associated with peer victimization because gonadal and adrenal puberty, two independent processes, have either been conflated or adrenal puberty timing has been ignored. In addition, previous research has overlooked the possibility of reverse causality—that peer victimization might drive pubertal timing, as it has been shown to do in non-human primates. To fill these gaps, we followed 265 adolescents (47% female) prospectively across three-time points …


Infant Hedonic/Anhedonic Processing Index (Hapi-Infant): Assessing Infant Anhedonia And Its Prospective Association With Adolescent Depressive Symptoms, Jessica L. Irwin, Elysia Poggi Davis, Curt A. Sandman, Tallie Z. Baram, Hal S. Stern, Laura M. Glynn Feb 2024

Infant Hedonic/Anhedonic Processing Index (Hapi-Infant): Assessing Infant Anhedonia And Its Prospective Association With Adolescent Depressive Symptoms, Jessica L. Irwin, Elysia Poggi Davis, Curt A. Sandman, Tallie Z. Baram, Hal S. Stern, Laura M. Glynn

Psychology Faculty Articles and Research

Background

Anhedonia, an impairment in the motivation for or experience of pleasure, is a well-established transdiagnostic harbinger and core symptom of mental illness. Given increasing recognition of early life origins of mental illness, we posit that anhedonia should, and could, be recognized earlier if appropriate tools were available. However, reliable diagnostic instruments prior to childhood do not currently exist.

Methods

We developed an assessment instrument for anhedonia/reward processing in infancy, the Infant Hedonic/Anhedonic Processing Index (HAPI-Infant). Exploratory factor and psychometric analyses were conducted using data from 6- and 12-month-old infants from two cohorts (N = 188, N = 212). …

Perceived Neighborhood Disorder And Type 2 Diabetes Disparities In Hispanic, Black, And White Americans, Min Ying Yu, Alfredo J. Velasquez, Belinda Campos, Jennifer W. Robinette

Psychology Faculty Articles and Research

Introduction: Approximately 32 million Americans have type 2 diabetes, and that number continues to grow. Higher prevalence rates are observed among certain subgroups, including members of marginalized racial/ethnic groups as well as residents of disordered neighborhoods (i.e., those with more trash and vandalism). Institutionalized discriminatory practices have resulted in disproportionate representation of marginalized racial/ethnic groups in disordered neighborhoods compared to non-Hispanic Whites. These neighborhood disparities may partially contribute to health disparities, given that signs of neighborhood disorder often relate to a general withdrawal from the neighborhood, minimizing opportunities for both physical and social engagement. Yet, research suggests variability across …

Psychology Faculty Articles and Research

High unpredictability has emerged as a dimension of early-life adversity that may contribute to a host of deleterious consequences later in life. Early-life unpredictability affects development of limbic and reward circuits in both rodents and humans, with a potential to increase sensitivity to stressors and mood symptoms later in life. Here, we examined the extent to which unpredictability during childhood was associated with changes in mood symptoms (anhedonia and general depression) after two adult life stressors, combat deployment and civilian reintegration, which were assessed ten years apart. We also examined how perceived stress and social support mediated and /or moderated …

Communication Sciences and Disorders Faculty Articles and Research

Like speech, signs are composed of discrete, recombinable features called phonemes. Prior work shows that models which can recognize phonemes are better at sign recognition, motivating deeper exploration into strategies for modeling sign language phonemes. In this work, we learn graph convolution networks to recognize the sixteen phoneme “types” found in ASL-LEX 2.0. Specifically, we explore how learning strategies like multi-task and curriculum learning can leverage mutually useful information between phoneme types to facilitate better modeling of sign language phonemes. Results on the Sem-Lex Benchmark show that curriculum learning yields an average accuracy of 87% across all phoneme types, outperforming …

Theories Of Consciousness And A Life Worth Living, Liad Mudrik, Myrto Mylopoulos, Niccolo Negro, Aaron Schurger

Psychology Faculty Articles and Research

What is it that makes a life valuable? A popular view is that life’s moral worth depends in some way on its relationship to consciousness or subjective experience. But a practical application of this view requires the ability to test for consciousness, which is currently lacking. Here, we examine how theories of consciousness (ToCs) can help do so, focusing especially on difficult cases where the answer is not clear (e.g. fetuses, nonhuman animals, unresponsive brain-injured patients, and advanced artificial systems). We consider five major ToCs and what predictions they offer: Integrated information theory, Higher-Order Thought Theory, Recurrent Processing Theory, Global …


The Impact Of Vaccinations And Chronic Disease On Covid Death Rates, James L. Doti Aug 2023

The Impact Of Vaccinations And Chronic Disease On Covid Death Rates, James L. Doti

Economics Faculty Articles and Research

This study presents a theoretical and empirical regression model to measure the efficacy of vaccinations in reducing COVID death rates across states over the 3/10/21 to 12/28/22 period. During that period, it was estimated that the availability of vaccinations resulted in a reduction of 427,000 COVID deaths in the nation. To arrive at that estimate, other covariants were held constant. In particular, it was found that chronic disease should be included as an explanatory variable to arrive at unbiased measures of the efficacy of vaccinations in reducing deaths. In addition, the percentage of people over the age of 65 was …

The severity of infectious disease outbreaks is governed by patterns of human contact, which vary by geography, social organization, mobility, access to technology and healthcare, economic development, and culture. Whereas globalized societies and urban centers exhibit characteristics that can heighten vulnerability to pandemics, small-scale subsistence societies occupying remote, rural areas may be buffered. Accordingly, voluntary collective isolation has been proposed as one strategy to mitigate the impacts of COVID-19 and other pandemics on small-scale Indigenous populations with minimal access to healthcare infrastructure. To assess the vulnerability of such populations and the viability of interventions such as voluntary collective isolation, we …
