Objectives: This study aims to examine associations between changes in physical education, anxiety, cardiorespiratory fitness (CRF), and muscular fitness (MF) in adolescents. Methods: Participants were Finnish students (baseline: n = 1,147; 11.27 [0.32] years). Data were collected over 4 years (2017-2021). CRF was assessed with the 20 m shuttle…

Background: Various psychosocial variables are critical predictors of students' recess experiences. It is still relatively unknown how self-perceptions of bullying and body size impact recess physical activity (PA) for certain groups of students. The purpose of this study was to examine group differences and relationships in levels of…

Ample evidence documents rising student obesity in summer months and falling student obesity during the school year. One theory for this pattern is that out-of-school days lack some of the structure and health-promoting behaviors that schools provide. Given this observed seasonal pattern, a natural question is whether there is room for policies…

Background: Cardiorespiratory fitness (CRF) plays a significant role in health and academic performance in youth. The purpose of this study was to examine the longitudinal relationship between CRF and academic performance from fifth to eighth grade among a large, diverse, and state-wide cohort of students, and to determine the extent to which the…

The paper investigates gender differences in coolness dynamics among early and middle adolescents in a Hungarian panel dataset, which followed students from grade 5 (age 11-12) to grade 8 (age 14-15). Drawing on Gender Prototypicality Theory, we expected significantly different gendered patterns in the association between coolness and various…

Objective: To evaluate the effects of a nutrition education programme conducted during health education lessons on students' adherence to the Mediterranean Diet (MD) and their body mass index (BMI). Design: Quasi-experimental pre-test/post-test research design: two study conditions (intervention and control groups). Setting: Two urban schools, the…

This cross-sectional study was carried out to investigate the self-perception of primary school students aged 10-14 and their attitudes toward obese children (n = 693). There was a weak, positive, and highly significant correlation between the mean scores for the overall Attitude Toward Obese Children Scale, the Self-Perception Profile for…

Digital game addiction was classified as a disease by the World Health Organization. It is characterized by impaired control over gaming and increasing priority given to gaming over other activities. Especially for school-age children, there are concerns about the effects of gaming addiction on health problems that are difficult to treat later and…

Children's health literacy is a crucial pillar of health. This study is aimed to examine the association between health literacy and weight status among Greek schoolchildren aged 10 to 12 years old. A population-based, cross-sectional observational study enrolling 1,728 students (795 boys), aged 10 to 12 years old, was conducted during school…

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…

Background: The accuracy of students' heights and weights measured by school staff for body mass index (BMI) screening/reporting has not been established. This study examined school staffs' measurement accuracy, comparing accuracy by staff- and student-level characteristics. Methods: School staff and researchers measured the height and weight of…

This study evaluated feasibility, acceptability, and preliminary efficacy of a 12-week "Guys/Girls Opt for Activities for Life" (GOAL) intervention on 10- to 13-year-old adolescents' body mass index (BMI), percent body fat, physical activity (PA), diet quality, and psychosocial perceptions related to PA and healthy eating.…

The aim of this study was to analyze the importance of some physical fitness and motor skills for children between 11-13 years at elementary school. A total of 114 primary school children participated as volunteers with a means age of 10.80 ± 0,40 for 5th grade and 12.83 ± 0,38 for 7th grade. In this study, some motor tests were used to detect…

The present study examined associations between effortful control, a trait marker of self-regulation, adaptive hypothalamic-pituitary-adrenal (HPA) system functioning (as reflected by the cortisol awakening response [CAR]), and concurrent and longitudinal depressive problems, in a sample of preadolescent Latino youth (N = 119, mean age = 11.53…
