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…

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…

Background: Although many studies found a positive association between physical activity (PA) and academic performance (AP), most did not consider important variables of school setting and students' self-concept. Aims: To analyze the association between moderate-to-vigorous PA (MVPA) and AP in adolescents, considering potential confounding…

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…

The current study was designed to examine one possible weight stigma-reduction mechanism: school-level weight diversity. It was hypothesized that greater weight diversity among same-sex peers at school would attenuate the negative association between weight and academic achievement. Across 26 urban public middle schools, 5,991 sixth-grade students…

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 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…

Guided by the biopsychosocial model, we examined (a) the prevalence of weight control behaviors (WCBs; i.e., trying to stay the same weight, lose weight, gain weight, or do nothing about weight) among early adolescent boys by race/ethnicity and grade level, and (b) how the boys' perceptions of sociocultural pressures (from parents, peers, and…

Emotional eating, defined as eating in response to affect, may increase during early adolescence, a time of heightened emotionality and increased prevalence of emotional disorders. We investigated change in emotional eating, while also testing the influence of social-emotional risk factors. Study participants (N = 379, mean age [M[subscript age]]…
