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…

We estimate the effect of universal free school meal access through the Community Eligibility Program (CEP) on child body mass index (BMI). Through the CEP, schools with high percentages of students qualified for free or reduced-priced meals can offer free breakfast and lunch to all students. With administrative data from a large school district…

We estimate the effect of universal free school meal access through the Community Eligibility Program (CEP) on child BMI. Through the CEP, schools with high percentages of students qualified for free or reduced-priced meals can offer free breakfast and lunch to all students. With administrative data from a large school district in Georgia, we use…

This paper investigates the impact of extending free school lunch to all students, regardless of income, on academic performance in New York City middle schools. Using a difference-in-differences design and unique longitudinal, student-level data, we derive credibly causal estimates of the impacts of "Universal Free Meals" (UFM) on test…

Sport Education is a curriculum model designed to provide all students with authentic sport experiences, regardless of their individual characteristics. Research showing the effectiveness of the model in promoting physical activity (PA) levels is still scant. In addition, interventions have mostly included invasion games as the main content, thus…

Background: Associations between school participation in an academic medical center-supported school-based wellness initiative and programmatic components implemented with change in average student body mass index (BMI) over time were examined. Methods: This was an observational study of 103 K-12 South Carolina schools over school years 2014-2018,…

Background: Moderate-to-vigorous physical activity (MVPA) declines during adolescence, particularly among girls. In this randomized control trial, we examined MVPA in a physical activity intervention compared to physical education (PE) class as usual (TAU), stratified by sex and weight classification. Standardized BMI (zBMI) overtime was also…

This study examined the effect of a 10-week activity tracker, companion social website, and text messaging intervention on body mass index (BMI), body fat percentage, physical fitness, and physical activity (PA) self-efficacy of children. Children (n = 98) were assigned to one of three groups: activity tracker group, text messaging group, and…

College students often experience and report feeling stressed within the context of their daily lives. This empirical study examines the effect of personal stress on academic performance in an introductory economics course at a representative regional university. 105 students were surveyed and completed a standardized psychometric instrument…

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.…

Background: Overweight and obese body mass index (BMI) status affects an increasing number of children in the United States. The school setting has been identified as a focus area to implement obesity prevention programs. Methods: A database search of PubMed, Education Search Complete, and Cumulative Index to Nursing and Allied Health Literature…

The aim of this study was to investigate the effect of a body image group counselling program on adolescent girls in the context of Positive Psychology and Positive Psychotherapy. The sample set consisted of 22 female students, 11 in the experimental group and the other 11 in the control group, and they are all in the 9th grade and have negative…

Background: Motivating Adolescents with Technology to CHOOSE Health™ (MATCH) is an educational and behavioral intervention in seventh grade. Methods: Teachers in 2 schools delivered the MATCH curriculum, with 1 control school. Using a quasi-experimental design, outcome measures included lessons completed, body mass index (BMI), BMI z-score (zBMI),…

Participation in the federally-subsidized school breakfast program often falls well below its lunchtime counterpart. To increase take-up, many districts have implemented Breakfast in the Classroom (BIC), offering breakfast directly to students at the start of the school day. Beyond increasing participation, advocates claim BIC improves academic…
