Calories in, Calories Out: Food and Exercise in Public Elementary Schools, 2005

摘要

The rate of obesity among school-age children has become a national concern, with the number of overweight children aged 6 to 11 more than tripling over the past three decades (U.S. Government Accountability Office 2005). One way to address this health issue in schools is to emphasize an 'energy balance'approach-calories consumed versus calories expended-to support healthy eating and an active lifestyle. This report is based on a survey conducted by the National Center for Education Statistics (NCES) in the Institute of Education Sciences, U.S. Department of Education. It presents current national information for public elementary schools on the availability of foods outside of full school meals, the opportunities for students to engage in physical activity, and the physical assessment of students.
