Implementation of the Healthy Hunger-Free Kids Act of 2010 will provide an opportunity for school nurses to intervene in the serious childhood obesity problem in the United States. Major changes in the management of the National School Lunch Program (NSLP) will likely challenge schools yet may provide the impetus for a collaborative effort by the…

Problem: Priority health-risk behaviors contribute to the leading causes of morbidity and mortality among youth and adults. Population-based data on these behaviors at the national, state, and local levels can help monitor the effectiveness of public health interventions designed to protect and promote the health of youth nationwide. Reporting…

Children in the United States are less active and more overweight today than at any time in history, and there has been a dramatic increase in obesity. Obesity can lead to physical and psychological health issues. Many adults recognize the health issues that can stem from childhood obesity, but may not be aware of the clear implication of the…

Background: Environmental and policy influences are potentially the most powerful and yet the least understood strategies for reversing the current childhood obesity epidemic. Methods: This essay focuses on the school lunch environment and examines the key legal and policy factors that affect competitive foods or foods of minimal nutritional value…

Liliana Escobar-Chaves and Craig Anderson investigate two important trends among American youth and examine the extent to which the two trends might be related. First, the authors note that U.S. youth are spending increasing amounts of time using electronic media, with the average American youngster now spending one-third of each day with some…

The national Youth Risk Behavior Survey (YRBS) monitors priority health risk behaviors that contribute to the leading causes of death, disability, and social problems among youth and adults in the United States. The national YRBS is conducted every two years during the spring semester and provides data representative of 9th through 12th grade…

Statewide physical fitness testing is gaining popularity in the United States because of increased childhood obesity levels, the relations between physical fitness and academic performance, and the hypothesized relations between adult characteristics and childhood physical activity, physical fitness, and health behaviors. Large-scale physical…

This dissertation evaluates the impact of elementary school policies on child health behaviors and obesity in the United States. Two chapters address nutrition policies, two chapters address physical activity policies, and a final chapter estimates the health care cost savings associated with a decline in childhood obesity prevalence. The use of…

America has a serious weight problem. Two-thirds of adults and nearly one-fifth of children in the United States are overweight, placing them at greater risk for heart disease, diabetes, and other chronic diseases including cancer and arthritis. Furthermore, obesity and its related health problems are placing a major strain on the U.S. health care…

A critique of the role of various sports-related initiatives that have been developed to address the obesity epidemic currently…

Associations between sleep and the body mass index (BMI) and overweight status of children and adolescents were estimated using longitudinal data from a nationally representative sample of 2,281 children aged 3-12 years at baseline. Controlling for baseline BMI, children who slept less, went to bed later, or got up earlier at the time of the first…

The study of physical activity behavior in youth generally lacks a sufficient theoretical foundation for examining variables that influence that behavior. This is a major limitation because theory guides the search for determinants of behavior and the subsequent interplay between research findings and application. Theory offers a systematically…
