Limited data are available on the contributory and compensatory relationships between physical education and physical activity in children. Four hundred eighty-five (280 girls) children in first through sixth grades wore sealed pedometers during waking hours, including normally scheduled physical education lessons. The least, moderately, and most…

Objective and Participants: The authors investigated the effect of physical activity (PA), fruit and vegetable intake, and alcohol use on 6-month weight change in 193 college freshmen (78.8% white, 88.2% women, 94.5% on a meal plan). Methods: The authors administered a Web-based survey in fall 2002 (baseline) and spring 2003 (follow-up). Results:…

Objective: To evaluate a modified curriculum for the 6-session Texas Expanded Food and Nutrition Education Program (EFNEP) promoting healthful home food environments and parenting skills related to obesity prevention. Design: Two-group randomized control trial; intervention versus usual EFNEP curriculum. Setting: Texas EFNEP classes. Participants:…

The purpose of this investigation was to examine overweight students' perceptions of and experiences in physical education. Specifically, the applicability of learned helplessness as a framework to understand their experiences was explored. Participants were seven female and five male high school students whose body mass index was at or higher…

Background: Childhood obesity is a major public health threat. Increased fitness may have a positive influence on cognitive performance in both adults and children. Purpose: To examine which aspects of children's fitness assessment are associated with their performance on four different academic areas. Methods: FITNESSGRAM measures aerobic…

To investigate the role of body size in social networks, this study estimated cross-nested multilevel network models (p2) with longitudinal data from the 16 saturated schools in the National Longitudinal Study of Adolescent Health. As body mass index increased, the likelihood of being nominated by schoolmates as friends--but not the likelihood of…

Adolescent girls with body dissatisfaction (N = 481, SD = 1.4) were randomized to a dissonance-based thin-ideal internalization reduction program, healthy weight control program, expressive writing control condition, or assessment-only control condition. Dissonance participants showed significantly greater decreases in thin-ideal internalization,…

Introduction: The present study reports cross-cultural comparisons of body mass index (BMI) and growth in Prader-Willi syndrome, a neurodevelopmental disorder associated with obesity, growth restriction and mild learning disability. Our objectives were to: (1) compare rates of obesity in adults with Prader-Willi syndrome (PWS) in France, with data…

Background: Childhood obesity is an impending epidemic. This article is an overview of different interventions conducted in school settings so as to guide efforts for an effective management of obesity in children, thus minimizing the risk of adult obesity and related cardiovascular risk. Methods: PubMed and OVID Medline databases were searched…

The Institute of Medicine recommends school-based body mass index (BMI) screening as an obesity prevention strategy. While school nurses have provided height/weight screening for years, little has been published describing measurement reliability or process. This study evaluated the reliability of height/weight measures collected by school nurses…

Background: This study assessed parent reactions to school-based body mass index (BMI) screening. Methods: After a K-8 BMI screening program, parents were sent a letter detailing their child's BMI results. Approximately 50 parents were randomly selected for interview from each of 4 child weight-classification groups (overweight, at risk of…

One-third of the population of US children is considered obese and two-thirds of the adult population falls into the same category. These figures have tripled over the last 30 years. This demonstrates that the existing strategies to combat obesity do not work and it is time to look for alternatives. The recommendation is to turn the problem into a…

The authors reviewed the evidential basis of three environmental approaches to reducing population obesity: What are the effects of (a) taxing or subsidizing foods, (b) manipulating the ease of food access, and (c) restricting access to certain foods? A narrative review evaluated evidence using National Heart, Lung, and Blood Institute criteria.…

Understanding and promoting physical activity is critical to combat the growing obesity epidemic in the U.S. This study was designed to compare two 10-week physical activity programs among college students. One hundred and thirty-six undergraduate college students participated in this randomized posttest only control group study. Seventy-seven…

Parents of children in most elementary grades in Minnesota's Independent School District 191 receive an annual notice with potentially life-altering data for their children--and they are not state test scores, attendance rates, or grades. The notice contains the child's body mass index (BMI) score, which estimates whether the student has excess…
