Associations Between School Readiness and Obesity‐ and Inflammation‐Related Biomarkers in Low‐Income Preschoolers Within the Healthy Kids Study

Previous research suggests obesity is negatively related to cognitive functioning and academic outcomes in addition to physical health. However, not much is known about this association in early childhood or potential physiological underpinnings. Biomarkers related to obesity have been associated with cognition, in particular the adipokine leptin, and pro‐inflammatory cytokines including interleukin‐6 (IL‐6), tumor necrosis factor‐alpha (TNF‐alpha) and C‐reactive protein (CRP). These associations may be further exacerbated for children who experience early life stress. With a sample of low‐income preschoolers, the current study examined associations between obesity‐related biomarkers and aspects of behavioral and cognitive school readiness. Partial correlations controlling for child age show hypothesized negative associations between pro‐inflammatory cytokines and school readiness, while leptin was positively associated with cognitive school readiness and body mass index (BMI) z‐score. Findings suggest connections between obesity, physiology, and school readiness need further examination, but may have implications for early childhood education and health interventions.     

Low‐Income Ethnically Diverse Children's Engagement as a Predictor of School Readiness Above Preschool Classroom Quality

This study examined whether children's observed individual engagement with teachers, peers, and tasks related to their school readiness after controlling for observed preschool classroom quality and children's baseline skills. The sample included 211 predominately low‐income, racially/ethnically diverse 4‐year‐old children in 49 preschool classrooms in one medium‐sized U.S. city. Results indicated that children's positive engagement with (a) teachers related to improved literacy skills; (b) peers related to improved language and self‐regulatory skills; and (c) tasks related to closer relationships with teachers. Children's negative engagement was associated with lower language, literacy, and self‐regulatory skills, and more conflict and closeness with teachers. Effect sizes were small to medium in magnitude, and some expected relations between positive engagement and school readiness were not found.     

Sleep Disturbance and Expressive Language Development in Preschool‐Age Children With Down Syndrome

Recent evidence has suggested that sleep may facilitate language learning. This study examined variation in language ability in 29 toddlers with Down syndrome (DS) in relation to levels of sleep disruption. Toddlers with DS and poor sleep (66%, n = 19) showed greater deficits on parent‐reported and objective measures of language, including vocabulary and syntax. Correlations between sleep and language were found in groups with equivalent medical and social backgrounds and after control for relevant behavioral comorbidities, including autism symptoms. These results emphasize the important role of quality sleep in all children's expressive language development, and may help increase our understanding of the etiology of language deficits in developmental disorders, potentially leading to new treatment approaches.     

Preschool‐Age Problem Behavior and Teacher–Child Conflict in School: Direct and Moderation Effects by Preschool Organization

The hypothesis was tested that the new open‐group Norwegian day‐care centers would more than traditionally organized centers negatively affect (a) current and (b) future teacher–child relationships, and (c) the developmental legacy of preschool problem behavior. The focus was on eight hundred and fifty 4‐year‐olds from 153 centers who were followed up in first grade. Results of this natural quasi‐experiment revealed that children from open‐group centers (a) experienced less teacher–child closeness in preschool and (b) more teacher–child conflict in first grade, and (c) that high levels of preschool problem behavior forecast especially high levels of future teacher–child conflict, but only for children from open‐group centers. Results highlight the importance of spatial and social organization of day care and their translational implications.     

Protective Factors for School Readiness Among Children in Poverty

The economic status of families and their children's learning outcomes are closely related. For example, children living in poverty tend to score worse on measures of reading and math performance than their more affluent peers, and this achievement gap is present by kindergarten. In this study, we identified protective factors associated with school readiness among an Arizona sample of children living at or below the federal poverty line (N = 230). Using multiple linear regression, we examined the association between assessments of school readiness, health status, childcare hours, home language, parent engagement, and parent education. We found that increased weekly childcare hours and better health were associated with higher proficiency in math, literacy, and approaches to learning, and may serve as resilience factors for children in poverty that may contribute to closing the achievement gap.     

Differential Third‐Grade Outcomes Associated With Attending Publicly Funded Preschool Programs for Low‐Income Latino Children

This study examined the third‐grade outcomes of 11,902 low‐income Latino children who experienced public school pre‐K or child care via subsidies (center‐based care) at age 4 in Miami‐Dade County, Florida. Regression and propensity score analyses revealed that children who experienced public school pre‐K earned higher scores on standardized assessments of math and reading in third grade and had higher grade point averages than those who attended center‐based care 4 years earlier. The sustained associations between public school pre‐K (vs. center‐based care) and third‐grade outcomes were mediated by children's kindergarten entry preacademic and social–behavioral skills, and among English‐language learners, English proficiency. Implications for investing in early childhood programs to assist with the school readiness of young Latino children in poverty are discussed.     

Child‐Care Subsidies and School Readiness in Kindergarten

The federal child‐care subsidy program represents one of the government's largest investments in early care and education. Using data from the nationally representative Early Childhood Longitudinal Study–Birth Cohort, this study examines associations, among subsidy‐eligible families, between child‐care subsidy receipt when children are 4 years old and a range of school readiness outcomes in kindergarten (sample n ≈ 1,400). Findings suggest that subsidy receipt in preschool is not directly linked to subsequent reading or social‐emotional skills. However, subsidy receipt predicted lower math scores among children attending community‐based centers. Supplementary analyses revealed that subsidies predicted greater use of center care, but this association did not appear to affect school readiness.

Immediate Effects of a School Readiness Intervention for Children in Foster Care

Research Findings: School readiness is a strong predictor of adjustment in elementary school and beyond. Children in foster care are at particular risk for academic and social difficulties in school. Limitations in self-regulatory skills and caregiver involvement among these children might contribute to a lack of school readiness. This study presents the immediate effects on school readiness of a targeted, short-term intervention designed to improve children's early literacy, prosocial, and self-regulatory skills during the summer before kindergarten entry: Kids in Transition to School. Using a randomized controlled trial design, we assigned 192 children in foster care to either an intervention or services as usual comparison condition. Multimethod, multi-informant assessments were conducted immediately prior to and following the completion of the intervention. The results from structural equation modeling indicated that the intervention had significant positive effects on early literacy and self-regulatory skills. Practice or Policy: An efficacious, short-term, readily scalable, theoretically based intervention targeted at specific vulnerabilities for children in foster care may help to improve the school readiness and eventual school adjustment of these children.

Examining the Relationship Between Neighborhood Environment and School Readiness for Kindergarten Children

In the current research project, the relationship between neighborhood environment and school readiness was investigated. To measure neighbourhood environment, data from the 2001 Canadian Census were used, while school readiness was measured using the Early Development Instrument (EDI). EDI data were collected for kindergarten children across British Columbia, Canada, in the school years 2000/2001 through 2004/2005 by the Human Early Learning Partnership. A hierarchical linear modeling approach to data analysis was taken given the complex structure of the data (children nested within neighborhoods). Results from this study suggest that neighborhood environment is related to children's school readiness outcomes as measured by the EDI. Specifically, all 5 EDI domains were significantly predicted by between 2 and 8 of 13 neighborhood variables that were conceptually grouped into 8 categories accounting for family structure, income, education, Aboriginal status, language, labor force occupations, employment rates, and domestic work. Overall, 3 themes emerged from this study that suggest neighborhood-level sources of social wealth: the importance of neighborhood culture, stability, and heterogeneity in promoting better school readiness outcomes for children. Formulations regarding areas for future research are presented.

Pathways to School Readiness: Executive Functioning Predicts Academic and Social–Emotional Aspects of School Readiness

The current study specified the extent to which hot and cool aspects of executive functioning predicted academic and social‐emotional indicators of school readiness. It was unique in focusing on positive aspects of social–emotional readiness, rather than problem behaviors. One hundred four 3–5‐year‐old children completed tasks measuring executive functioning, social–emotional readiness, academic readiness, and vocabulary. As expected, age predicted executive functioning components and social–emotional readiness. Moreover, working memory and inhibitory control directly predicted academic readiness, whereas delay of gratification predicted social–emotional readiness. Working memory and inhibitory control predicted delay of gratification, consistent with the notion that simpler executive functions may set the stage for more complex executive functions. Interestingly, social–emotional readiness predicted academic readiness. These findings confirm that hot and cool aspects of executive functioning are related to social–emotional and academic school readiness.     

Within‐High‐School Versus Across‐High‐School Scaling of Admissions Assessments: Implications for Validity and Diversity Effects

Previous research has established that SAT scores and high school grade point average (HSGPA) differ in their predictive power and in the size of mean differences across racial/ethnic groups. However, the SAT is scaled nationally across all test takers while HSGPA is scaled locally within a school. In this study, the researchers propose that this difference in how SAT scores and HSGPA are scaled partially explains differences in validity and subgroup differences. Using a large data set consisting of 170,390 students each of whom matriculated at one of 114 separate colleges, the researchers find that awarding SAT scores by ranking SAT within a high school generally results in substantial reduction in the size of subgroup mean differences for this predictor. However, validity for predicting first‐year GPA is also reduced by a small amount. Conversely, placing HSGPA onto a nationally normed metric through the use of multiple regression procedures results in a moderate increase in the size of subgroup mean differences, while also producing a small increase in validity. Taken together, these findings suggest that differences in predictor scaling can partially explain differences in the size of subgroup mean differences between HSGPA and SAT scores and have implications for predictive power.     

Baseline Hypothalamic–Pituitary–Adrenal Axis and Parasympathetic Nervous System Activity Interact to Predict Executive Functions in Low‐Income Children

We examined interactions between baseline hypothalamic–pituitary–adrenal (HPA) axis and parasympathetic nervous system (PNS) activity in relation to executive functions (EF) in a sample (n = 1,005) of children in low wealth, nonurban communities at age 48 months. Salivary cortisol and respiratory sinus arrhythmia (RSA) represented baseline HPA axis and PNS activity, respectively. The interaction between RSA and cortisol predicted EF such that children with either lower RSA and lower cortisol, or higher RSA and higher cortisol had higher EF scores. These findings suggest a potential compensatory relation in which the PNS and HPA axis counterbalance each other to support cognition.     

Early Childhood Predictors of Severe Youth Violence in Low‐Income Male Adolescents

Using a cohort of 310 low‐income male adolescents living in an urban community and followed prospectively from 18 months through adolescence (ages 15–18 years), the current study examined whether individual, family, and community risk factors from ages 18 to 42 months were associated with adolescents' violent behavior, as indexed by juvenile petitions. Results of multivariate analyses indicated that although family income was the only factor to discriminate those with no arrest record from those with nonviolent arrests, rejecting parenting, child oppositional behavior, emotion regulation, and minority status during the toddler period contributed unique variance in distinguishing male adolescents arrested for violent behavior compared to those never arrested and those arrested for nonviolent behavior. Implications for prevention efforts are discussed.
