Summary In the United States, data from the 2007-2008 National Health and Nutrition Examination Survey indicate that nearly 34 percent of adults aged 20 years or older are obese and about 68 percent are overweight or obese. Among children and adolescents aged 2 to 19, nearly 17 percent are obese and close to 32 percent are overweight or obese. The epidemic reflected by these figures poses major challenges for policy makers, public health professionals, and other decision makers. Federal health authorities have called for decisive action to address this epidemic for more than a decade, and their appeals have increased in urgency in recent years. Their alarm is linked to the adverse health outcomes of obesity and overweight, including potential negative effects on quality of life and life expectancy. It is also triggered by the negative economic impact of these levels of obesity. Automation studio 5.7 professional edition pdf. A recent analysis calculated that the annual national medical burden of obesity is nearly 10 percent of all medical spending and could have risen to $147 billion per year by 2008. INTRODUCTION Policy makers and practitioners who take action to address this epidemic need evidence to explain why the actions are needed and to help determine what actions to take and how to go about them. They also need evidence to determine whether the intended results are obtained, who benefits, and whether there are positive or negative side effects that deserve attention. Summary Bridging Report Template WordIdeally, there would be ready sources of such evidence at hand relevant to these information needs. Unfortunately, a review of the existing evidence base reveals a striking contrast between the high prevalence and consequent importance of addressing obesity and the paucity of the knowledge base with which to inform prevention efforts. Specifically for evidence-based obesity prevention efforts, a body of intervention research on policy and environmental approaches is largely absent from the literature. THE NEED FOR A NEW FRAMEWORK The scenarios in Boxes and, respectively, illustrate the need to assist decision makers in finding evidence to inform decisions and to help researchers determine useful areas of study. Considerable progress has been made in building on the strengths of methods used in evidence-based medicine to develop research methods and evidence standards applicable to decision making about other population-level health problems. Leveraging these accomplishments holds the potential to advance understanding of how to develop and evaluate evidence for use in decision making on obesity prevention. The Institute of Medicine Committee on an Evidence Framework for Obesity Prevention Decision Making was formed to address these challenges.
