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…

Children's motor competence (MC) levels tend to be low, and the investigation of variables that facilitate skillfulness is an important concern. The socioecological model is a useful framework to explore factors that influence MC and to inform the development of targeted interventions. This cross-sectional study aimed to perform an exploratory…

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…

Objective: Children's lifestyle behaviours significantly affect childhood obesity. The impact of a body mass index reduction intervention applied to secondary school students on their eating behaviour, physical activity, sleep quality and obesity was in the focus of this research. Method: A quasi-experimental pre-post design was employed. The…

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…

Sport involvement may offer physical and psychological benefits to early adolescents beyond those accrued through physical activity (PA). Those benefits, though, may be moderated by gender. The purpose of this study was to examine these potential benefits in a middle school population. The sample consisted of 629 sixth graders enrolled in a…

School-age children with overweight or obesity continue to be problematic in the United States, and are associated with many health, social, and financial problems. Schools provide an excellent venue in which to promote healthy weight in students, and school nurses are well-positioned to play an essential role in controlling obesity. The number of…

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…

Purpose: Schools provide opportunities for children to accumulate recommended daily moderate to vigorous physical activity (MVPA). This study aimed to determine physical activity (PA) across the school day among elementary school children in Qatar. Methods: This cross-sectional study recruited 181 Grade 1 (5.8 ± 0.4 years) and Grade 4 (9.0 ± 0.5…
