Abstract
Abstract School food and physical activity (PA) environments can influence children’s dietary and physical activity behaviors. However, evidence on whether school environment is associated with students’ weight status is less definitive. In this study, we examined the association between students’ body mass index (BMI) and measures of school food and PA environments. We calculated BMI from nurse-measured data collected on 19,188 6-19-year-old students from 90 public schools in four low-income cities in New Jersey in 2015-2016. Based on a questionnaire administered to school nurses, we constructed 6 food and 3 PA indices capturing the healthfulness of key dimensions in the school food and PA environment domains. Multilevel linear models, stratified by school-level (elementary and secondary), examined the association between BMI z-scores and indices of the school environment. The food and PA domains were modeled separately and then combined. Joint significance of indices within each domain was tested. Analyses were conducted in 2019-2020. In the combined model for elementary schools, indices in both the food and PA domains were jointly significant (p=0.005 and p

Abstract Objectives To provide a systematic review of studies that investigated the effects of Active Break (AB) school-based interventions on Physical Activity (PA) levels, classroom behavior, cognitive functions, and academic performance in primary school children. Design Systematic review and meta-analysis. Methods Searches of electronic databases and grey literature, with no time restriction and up to April 2019, resulted in 22 intervention studies meeting the inclusion criteria. Quality ass...

Abstract Purpose Exposures to favorable environments in childhood, including those in schools, are associated with healthy habits among children. In this study, we developed a series of indices aimed at measuring students' exposure to different dimensions of the school food and physical activity (PA) environment. We implemented these indices to investigate how different aspects of the school food and PA environment changed over time and examined their correspondence with known changes in relevan...

Background School food environment policies may be a critical tool to promote healthy diets in children, yet their effectiveness remains unclear. Objective To systematically review and quantify the impact of school food environment policies on dietary habits, adiposity, and metabolic risk in children. Methods We systematically searched online databases for randomized or quasi-experimental interventions assessing effects of school food environment policies on children’s dietary habits, adiposity,...

In the United States, the National School Breakfast (SBP) and School Lunch Program (NSLP) meals are provided for free or at a reduced price to eligible children, and are a nutrition safety net for low income children. Consuming both meals could provide 58% of daily intake. This paper evaluates the contribution of SBP and NSLP meals to the dietary intakes of 5–18 year old children participating in the National Health and Nutrition Examination Surveys (NHANES) from 2007 through 2012. The participa...

OBJECTIVES: To compare adolescents’ physical activity at home, near home, at school, near school, and at other locations. METHODS: Adolescents ( N = 549) were ages 12 to 16 years (49.9% girls, 31.3% nonwhite or Hispanic) from 447 census block groups in 2 US regions. Accelerometers and Global Positioning System devices assessed minutes of and proportion of time spent in moderate to vigorous physical activity (MVPA) in each of the 5 locations. Mixed-effects regression compared MVPA across location...

The Institute of Medicine’s 2005 report, Preventing Childhood Obesity: Health in the Balance, used the Social Ecological Model (SEM) to describe the possible aetiology of the childhood obesity epidemic and also to lay the groundwork for future interventions(1). Based on ecological systems theory, the SEM postulates that changes in individual outcomes are influenced not only by individual-level factors such as age and gender, but also by interactions with the larger social, cultural, economic and...

Importance The latest US Department of Agriculture school meal and competitive venue standards (USDA standards) aim to improve student nutrition and health. However, significant opposition has been raised to their implementation. Objective To examine (1) the percentages of US middle and high school students who currently attend schools that have specific components of the USDA standards; (2) evidence that the identified USDA standard components may be associated with student overweight/obesity; ...

Missing data are a common occurrence in real datasets. For epidemiological and prognostic factors studies in medicine, multiple imputation is becoming the standard route to estimating models with missing covariate data under a missing-at-random assumption. We describe ice, an implementation in Stata of the MICE approach to multiple imputation. Real data from an observational study in ovarian cancer are used to illustrate the most important of the many options available with ice. We remark briefl...
