Socio-ecological domains and adolescent mental health: An application of the dual-factor model.

Comprehensive assessment of mental health includes wellbeing and psychopathology. Using the dual-factor model of mental health, this study explored associations between socioecological domains and mental health profiles and subsequent moderations by sex, race and ethnicity, and age. Cross-sectional data were from the Environmental influences on Child Health Outcomes (ECHO) Cohort (N = 2826).

PedBE age and age acceleration in umbilical vein endothelial cells: an examination of infant birth outcomes.

The current study examines the application of the Pediatric-Buccal-Epigenetic (PedBE) clock, designed for buccal epithelial cells, to endothelia. We evaluate the association of PedBE epigenetic age and age acceleration estimated from human umbilical vein endothelial cells (HUVECs) with length of gestation and birthweight in a racially and ethnically diverse sample (analytic sample = 333). PedBE age was positively associated with gestational age at birth ( = 0.

Longitudinal patterns of adversity from childhood to adolescence: Examining associations with mental health through emerging adulthood using a random-intercept latent transition analysis.

Childhood adversity can have detrimental impacts on life course mental and physical health. Timing, nature, severity, and chronicity of adversity are thought to explain much of the variability in health and developmental outcomes among exposed individuals. The current study seeks to characterize heterogeneity in adverse experiences over time at the individual, family, and neighborhood domains in a cohort of predominantly Black children (85% Black and 15% White, 46.

Increasing Maternal Anxiety in the Pre- to Postpartum Transition Predicts Infant Feeding Practices and Beliefs.

Objective: Anxiety symptoms increase for some mothers in the perinatal period. Little is known about how increasing anxiety relates to infant feeding beliefs or weight-for-length. We examined relationships between clinically meaningful increases in maternal anxiety symptoms and perceptions of infant feeding behaviors and weight-for-length.

Using Epigenetic Clocks to Characterize Biological Aging in Studies of Children and Childhood Exposures: a Systematic Review.

Biological age, measured via epigenetic clocks, offers a unique and useful tool for prevention scientists to explore the short- and long-term implications of age deviations for health, development, and behavior. The use of epigenetic clocks in pediatric research is rapidly increasing, and there is a need to review the landscape of this work to understand the utility of these clocks for prevention scientists. We summarize the current state of the literature on the use of specific epigenetic clocks in childhood.

The influence of sociodemographic factors and response style on caregiver report of infant developmental status.

Caregiver report is the most feasible way to assess early childhood development but is susceptible to the influences of response style and sociodemographic factors. In a sample of 571 caregiver-infant dyads (47.8% female; 48% White), we compared caregiver reports on the Ages and Stages Questionnaire-Third Edition (ASQ-3) with reports on a novel, web-based assessment, PediaTrac™.

What children do while they wait: The role of self-control strategies in delaying gratification.

Self-control plays an essential role in children's emotional and behavioral adjustment. A central behavioral indicator of self-control is the ability to delay gratification. Few studies have focused on understanding the heterogeneity of self-control behaviors that underlie children's ability to delay gratification.

Fetal heart rate responses to maternal sleep-disordered breathing.

Background: Maternal sleep-disordered breathing is associated with adverse pregnancy outcomes and is considered to be deleterious to the developing fetus. Maternal obesity potentiates sleep-disordered breathing, which, in turn, may contribute to the effect of maternal obesity on adverse fetal outcomes. However, only a few empirical studies have evaluated the contemporaneous effects of maternal sleep-disordered breathing events on fetal well-being.

More than meets the eye: Examining physiological and behavioral regulation during delay of gratification task.

Children continually encounter situations where they must regulate impulsive responses to achieve a goal, requiring both self-control (SC) and delay of gratification. We examined concurrent behavioral SC strategies (fidgeting, vocalizations, anticipation) and physiological regulation (heart rate [HR], respiratory sinus arrhythmia [RSA]) in 126 children (M (SD) = 5.4 (0.

Moving up but not getting ahead: Family socioeconomic position in pregnancy, social mobility, and child cognitive development in the first seven years of life.

Objectives: Understanding when and how socioeconomic position (SEP) influences cognitive development is key to reducing population inequalities in health and achievement. The objective of this study was to determine the unique association between prenatal family SEP and child cognitive development, and to determine whether marked postnatal social mobility was associated with improvements in child cognitive performance to age 7.

Methods: Data were from children enrolled in the US National Collaborative Perinatal Project (NCPP) (n = 28,761) during 1959-1965, a dataset large enough to observe marked mobility, which remains uncommon.

Measuring fetal heart rate and variability: Fetal cardiotocography versus electrocardiography.

Fetal heart rate variability is a key indicator of fetal neurodevelopment and well-being. Most studies have relied on Doppler-based fetal cardiotocography (fCTG) but recent technologies have made fetal electrocardiography (fECG) more widely available. We compared simultaneous recordings of fCTG and fECG in 131 fetuses twice during gestation (28 and 36 weeks) using a commercially available device (Monica AN24).

Children's Attention and Self-Regulatory Behavior Before and During the COVID-19 Pandemic.

Objective: The goal of this study was to investigate changes in children's self-regulatory behavior before and during the COVID-19 pandemic.

Method: Participants were parents of children aged 4 to 13 years (n = 45, mean 7.5, SD: 2.

Fetal neuromaturation in late gestation is affected by maternal sleep disordered breathing and sleep disruption in pregnant women with obesity.

Objective: Maternal sleep disordered breathing and sleep disruption have adverse effects on pregnancy outcomes through multiple potential pathophysiologic pathways. We hypothesize that disordered maternal sleep also adversely impacts the neuromaturation of the fetus.

Methods: Participants in this prospective observational study included 102 obese pregnant women (pre-pregnancy body mass index [BMI] of 30 or higher) at 36 weeks of pregnancy.

Fetal heart rate during maternal sleep.

Despite prolonged and cumulative exposure during gestation, little is known about the fetal response to maternal sleep. Eighty-four pregnant women with obesity (based on pre-pregnancy BMI) participated in laboratory-based polysomnography (PSG) with continuous fetal electrocardiogram monitoring at 36 weeks gestation. Multilevel modeling revealed both correspondence and lack of it in maternal and fetal heart rate patterns.

Risk factors for periventricular white matter injury in very low birthweight neonates.

Background: The development of periventricular white matter injury (PWMI) in the preterm neonate is the most common insult portending neurologic impairment and is linked with the later development of cerebral palsy. The pathogenesis of PWMI targets premyelinating oligodendrocytes of the periventricular region secondary to free radicals, cytokine toxicity, and excitatory neurotransmitters. The primitive nature of the vasculature in the developing fetal cortex lends to its predilection to PWMI and cerebral ischemia with less arterial anastomoses at arterial border zones and failure to compensate for global hypotension, termed the "pressure-passive" circulation.
