  • Fetal Cortisol Exposure and Offspring Socioemotional Development

    Open AccessElla‐Marie P Hennessey, Danielle A Swales et al.ARTICLEDevelopmental Psychobiology2026References: 100

    Glucocorticoids are a commonly proposed pathway through which offspring socioemotional development is shaped by the prenatal environment. However, studies have primarily assessed fetal cortisol exposure indirectly. We examine whether neonatal hair cortisol concentrations, an index of fetal cortisol exposure during the third trimester, are associated with early markers of offspring socioemotional development (negative affectivity and attention to …

  • Neonatal Hair Cortisol and Birth Outcomes

    LillyBelle K Deer, Catherine Demers et al.ARTICLEPsychosomatic Medicine2024

    OBJECTIVE: Prenatal stress physiology is often posited as a predictor of birth outcomes, including gestational age at birth and birthweight. However, research has predominantly relied on indicators in the maternal system, with few studies examining hormones of the fetal system. The current study focuses on fetal cortisol in the third trimester, as measured in neonatal hair, as a biological factor that might be associated with birth outcomes (gest…

  • Biological and behavioral pathways from prenatal depression to offspring cardiometabolic risk

    Open AccessJenalee R Doom, LillyBelle K Deer et al.ARTICLEDevelopmental Psychology2024

    Given prior literature focused on the Developmental Origins of Health and Disease framework, there is strong rationale to hypothesize that reducing depression in the prenatal period will cause improvements in offspring cardiometabolic health. The current review outlines evidence that prenatal depression is associated with offspring cardiometabolic risk and health behaviors. We review evidence of these associations in humans and in nonhuman animal…

  • Latent class analysis of maternal depression from pregnancy through early childhood

    Open AccessDaniel Ewon Choe, LillyBelle K Deer et al.ARTICLEDevelopmental Psychology2023Cited by: 1

    Prenatal and postpartum depression are highly prevalent worldwide, and emerging evidence suggests they contribute to impairments in children's executive functions. Studies of maternal depression, however, have focused on the postpartum and postnatal periods with relatively less consideration of prenatal influences on child development. This study of the large population-based Avon Longitudinal Study of Parents and Children U.K. cohort estimates l…

  • Respiratory Sinus Arrhythmia as a Physiological Resilience Marker for Children’s Health

    Nicholas V Alen, LillyBelle K Deer et al.ARTICLEPsychosomatic Medicine2022

    OBJECTIVE: The current study aimed to test parasympathetic nervous system activity, indexed through resting respiratory sinus arrhythmia (RSA) as a resilience factor that moderates the associations between socioeconomic status (SES), circulating cytokines, and somatic health in children. METHODS: The sample included 181 parent-child dyads (mean [standard deviation] child age = 9.91 [0.57] years; 50.3% boys). Parents reported on family income, par…

  • Associations of air pollution with peripheral inflammation and cardiac autonomic physiology in children

    Open AccessAnna M Parenteau, Nicholas V Alen et al.ARTICLENew Directions for Child and…2022

    Climate change-related disasters have drawn increased attention to the impact of air pollution on health. 122 children ages 9-11 years old, M(SD) = 9.91(.56), participated. Levels of particulate matter (PM2.5) near participants' homes were obtained from the Environmental Protection Agency. Cytokines were assayed from 100 child serum samples: IL-6, IL-8, IL-10, and TNFα. Autonomic physiology was indexed by pre-ejection period (PEP), respiratory si…

  • The Role of Childhood Executive Function in Explaining Income Disparities in Long-Term Academic Achievement

    Open AccessLillyBelle K Deer, Paul D Hastings et al.ARTICLEChild Development2020

    This study utilized data from the Avon Longitudinal Study of Parents and Children (N = 14,860) to examine whether early-life family income (age 0–5) predicted long-term academic achievement (age 16–18) and to investigate the role of executive function (EF) assessed multiple times across age 7–11 in explaining this association. Task-based EF was a significant mediator between early-life family income and later academic achievement in every model. …
