The current study examines the extent to which associations between internalizing problems, body mass index (BMI), and language skills from early (36 months) to late childhood (fifth grade) are due to relatively stable between-child differences, time-specific correlations, or cross-lagged paths. Data from the NICHD study, Early Child Care and…

One of the central goals of school physical education (PE) is to improve physical literacy in youth to nurture their ability, confidence, and desire to be physically active for life. The aim of this study was to examine the stability of the selected PE-centered physical literacy indicators on school students' objectively measured…

Purpose: The purpose of this study was to examine the predictive relationship among physical activity, health-related fitness, and on-task classroom behavior in children using a discriminant function analysis. Method: Participants were a convenience sample of children (N = 533; M[subscript age] = 8.8 ± 1.9 years) recruited from 77 1st- through…

Purpose: Based on the self-determination theory, this study explored the predictive strengths and relative importance of basic psychological needs (BPNs; i.e., autonomy, competence, and relatedness) in physical education in physical, cognitive, and psychological outcomes among Hispanic boys and girls. Methods: Fourth- and fifth-grade Hispanic…

This study was planned in order to analyze adolescent body image by age and gender, evaluate the relationship between adolescent body image and socio-cultural factors, and determine the extent to which variables such as age, gender, and Body Mass Index (BMI) can serve as predictors of the influential habits and strategies needed to achieve a…

Background: We examined prevalence, incidence, and trajectory of obesity from kindergarten through grade 8 in one of the first states to implement annual surveillance. Methods: Participants included 16,414 children enrolled in kindergarten in Arkansas in 2004 with complete body mass index (BMI) measurements in kindergarten and eighth grade.…

Background: We assessed the associations of 5 school and 7 neighborhood variables with fifth-grade students achieving Healthy Fitness Zone (HFZ) or Needs Improvement-Health Risk (NI-HR) on aerobic capacity (AC) and body composition (BC) physical fitness components of the state-mandated FITNESSGRAM® physical fitness test. Methods: Data for outcome…

The purpose of study 1 was to characterize energy expenditure (EE) during academic subjects and activities during an elementary school day. Children in 2nd-4th grades (N = 33) wore the SenseWear Armband (SWA) for five school days to measure EE. Teachers' logs were compared to SWA data to extract information about EE throughout the day. Energy…

Background: Schools are an important environmental context in children's lives and are part of the complex web of factors that contribute to childhood obesity. Increasingly, attention has been placed on the importance of school climate (connectedness, academic standards, engagement, and student autonomy) as 1 domain of school environment beyond…

The self-equilibrium hypothesis underlines the importance of having a strong core self, which is defined as a high and developmentally stable self-concept. This study tested this hypothesis in relation to body image (BI) trajectories in a sample of 1,006 adolescents (M[subscript age] = 12.6, including 541 males and 465 females) across a 4-year…

Background: The high rates of childhood overweight and obesity in the United States have generated interest in schools as sites for monitoring body mass index (BMI) information. This study established baseline values for a 5-year longitudinal assessment of BMI of elementary school children and examined variation across the schools, because little…

We examined the influence of physical and psychosocial variables on math and reading achievement test scores. Between 1 and 5 months prior to taking annual standardized reading and math tests, a sample of (N = 1,211) sixth through eight graders (53.7% girls; 57.2% White) self-reported levels of physical activity, academic self-beliefs, general…

Identifying early precursors of body mass index (BMI) and sports participation represents an important concern from a public health perspective and can inform the development of preventive interventions. This article examines whether kindergarten child self-regulation, as measured by classroom engagement and behavioral regulation, predicts healthy…

The present study examined the role of attachment toward mother and father as a predictor of eating pathology and weight gain among preadolescent boys and girls. Self-report questionnaires and adjusted body mass index (BMI) were administered from a community sample of 601 preadolescents (8-11 years; 48% female) at baseline and once again 1 year…

Our goal was to investigate the role of body mass index (BMI) and motor competence (MC) in children's physical activity (PA) levels during physical education (PE) classes. We assessed PA levels of 5-to-10-year old children ("n" = 264) with pedometers in four PE classes. MC was assessed using the TGMD-2 and BMI values were classified…
