In the 2001 Surgeon General's Call to Action to Prevent and Decrease Overweight and Obesity, former Surgeon General David Satcher, MD, PhD, warned of the negative effects of the increasing weight of American citizens and outlined a public health response to reverse the trend. The Surgeon General plans to strengthen and expand this blueprint for action created by her predecessor. Although the country has made some strides since 2001, the prevalence of obesity, obesity-related diseases, and premature death remains too high.

To battle the obesity epidemic in America, health care professionals and policymakers need relevant, useful data on the effectiveness of obesity prevention policies and programs. Bridging the Evidence Gap in Obesity Prevention identifies a new approach to decision making and research on obesity prevention to use a systems perspective to gain a broader understanding of the context of obesity and the many factors that influence it.

The increasing prevalence and burden of obesity transcends borders, straining populations worldwide. Data shows that 50 million girls, 74 million boys, 390 million women, and 281 million men were estimated to have obesity in 2016 (NCD-RisC, 2017). The National Academies of Sciences, Engineering, and Medicine convened a workshop on October 9, 2018 to address the status of the global obesity pandemic and discuss diverse approaches to manage this problem. Speakers examined the collective prevalence, costs, and drivers of obesity around the world using cross-cultural comparisons. Panels and group discussions emphasized the need to reduce disparities in prevention and treatment efforts and to generate new policy and system initiatives related to nutrition and physical activity worldwide. This publication summarizes the presentations and discussions from the workshop.

Children's health has made tremendous strides over the past century. In general, life expectancy has increased by more than thirty years since 1900 and much of this improvement is due to the reduction of infant and early childhood mortality. Given this trajectory toward a healthier childhood, we begin the 21st-century with a shocking developmentâ€"an epidemic of obesity in children and youth. The increased number of obese children throughout the U.S. during the past 25 years has led policymakers to rank it as one of the most critical public health threats of the 21st-century. Preventing Childhood Obesity provides a broad-based examination of the nature, extent, and consequences of obesity in U.S. children and youth, including the social, environmental, medical, and dietary factors responsible for its increased prevalence. The book also offers a prevention-oriented action plan that identifies the most promising array of short-term and longer-term interventions, as well as recommendations for the roles and responsibilities of numerous stakeholders in various sectors of society to reduce its future occurrence. Preventing Childhood Obesity explores the underlying causes of this serious health problem and the actions needed to initiate, support, and sustain the societal and lifestyle changes that can reverse the trend among our children and youth.

In a broad ranging review of current thinking on obesity, the authors criticise much of the existing research for being biased by ideological and moral assumptions.

Nearly one out of every three adults in America is obese and tens of millions of people in the United States are dieting at any one time. This has resulted in a weight-loss industry worth billions of dollars a year and growing. What are the long-term results of weight-loss programs? How can people sort through the many programs available and select one that is right for them? Weighing the Options strives to answer these questions. Despite widespread public concern about weight, few studies have examined the long-term results of weight-loss programs. One reason that evaluating obesity management is difficult is that no other treatment depends so much on an individual's own initiative and state of mind. Now, a distinguished group of experts assembled by the Institute of Medicine addresses this compelling issue. Weighing the Options presents criteria for evaluating treatment programs for obesity and explores what these criteria mean--to health care providers, program designers, researchers, and even overweight people seeking help. In presenting its criteria the authors offer a wealth of information about weight loss: how obesity is on the rise, what types of weight-loss programs are available, how to define obesity, how well we maintain weight loss, and what approaches and practices appear to be most successful. Information about weight-loss programs--their clients, staff qualifications, services, and success rates--necessary to make wise program choices is discussed in detail. The book examines how client demographics and characteristics--including health status, knowledge of weight-loss issues, and attitude toward weight and body image--affect which programs clients choose, how successful they are likely to be with their choices, and what this means for outcome measurement. Short- and long-term safety consequences of weight loss are discussed as well as clinical assessment of individual patients. The authors document the health risks of being overweight, summarizing data indicating that even a small weight loss reduces the risk of disease and depression and increases self-esteem. At the same time, weight loss has been associated with some poor outcomes, and the book discusses the implications for program evaluation. Prevention can be even more important than treatment. In Weighing the Options, programs for population groups, efforts targeted to specific groups at high risk for obesity, and prevention of further weight gain in obese individuals get special attention. This book provides detailed guidance on how the weight-loss industry can improve its programs to help people be more successful at long-term weight loss. And it provides consumers with tips on selecting a program that will improve their chances of permanently losing excess weight.
