During the past twenty years there has been a dramatic increase in obesity in the United States. An estimated thirty percent of adults in the US are obese; in 1980, only fifteen percent were. The issue is gaining greater attention with the CDC and with the public health world in general. This book will offer practical information about the methodology of epidemiologic studies of obesity, suitable for graduate students and researchers in epidemiology, and public health practitioners with an interest in the issue. The book will be structured in four main sections, with the majority of chapters authored by Dr. Hu, and some authored by specialists in specific areas. The first section will consider issues surrounding the definition of obesity, measurement techniques, and the designs of epidemiologic studies. The second section will address the consequences of obesity, looking at epidemiologic studies that focus on cardio-vascular disease, diabetes, and cancer The third section will look at determinants obesity, reviewing a wide range of risk factors for obesity including diet, physical activity and sedentary behaviors, sleep disorders, psychosocial factors, physical environment, biochemical and genetic predictors, and intrauterine exposures. In the final section, the author will discuss the analytical issues and challenges for epidemiologic studies of obesity.

Promotes the recognition, treatment, and prevention of conditions of overweight and obesity in the United States.

Obesity continues to accelerate resulting in an unprecedented epidemic that shows no significant signs of slowing down any time soon. The World Health Organization reports that in 2016, nearly 2 billion adults were overweight and that worldwide obesity has nearly tripled since 1975. Obesity: Global Impact and Epidemiology is an important tool in proving a link to new knowledge, serving researchers and clinicians. The field of obesity is evolving very quickly and there is an abundance of scientific data that has emerged and is emerging constantly. Researchers and physicians need new updated information about the epidemiology and global impact of obesity that come from authors that have a wide perspective in the field. For health professionals and researchers, there is a need to understand how obesity begins. While a simple question, the answer is very complex. - Serves as a starting point for in-depth discussions in academic settings, leading to revised and updated treatment options for practicing obesity-treatment specialists - Offers practical information about the methodology of epidemiologic studies of obesity - Updated important source of information for clinicians and scientists in the field of obesity

Despite adults’ best preventive efforts, childhood obesity is on the rise in most areas of the world, and with it the prevalence of Type 2 diabetes, hypertension, cardiovascular disease, and other formerly adult-onset conditions. Epidemiology of Obesity in Children and Adolescents takes the global ecological approach that is needed to understand the scope of the problem and its multiple causes and mechanisms, and to aid in developing more effective prevention and intervention programs. In the book’s first half, experts present a descriptive summary of youth obesity trends in ten world regions, broken down by age group, gender, socioeconomic status, and risk factors. Complementing these findings, part two reviews the evidence base regarding the variables, separately and in combination, having the most significant impact on young people’s development of obesity, including: • Genetic and nutrigenomic factors. • Environmental and psychosocial factors, such as family shopping and eating habits and access to healthful foods. • Neuroendocrine regulation. • Prenatal and neonatal factors (e.g., gestational diabetes of the mother). • Dietary factors, from nutrient content to young people’s food preferences. • Physical activity versus sedentary behavior. Epidemiology of Obesity in Children and Adolescents is necessary reading for the range of professionals involved in curtailing this epidemic, including public health specialists, epidemiologists, pediatricians, nurses, nutritionists, psychologists, health educators, and policymakers.

For the first time in decades, promising news has emerged regarding efforts to curb the obesity crisis in the United States. Obesity rates have fallen among low-income children in 18 states, the prevalence of obesity has plateaued among girls, regardless of ethnicity, and targeted efforts in states such as Massachusetts have demonstrably reduced the prevalence of obesity among children. Although the reasons for this turnaround are as complex and multifaceted as the reasons for the dramatic rise in obesity rates in recent decades, interventions to improve nutrition and increase physical activity are almost certainly major contributors. Yet major problems remain. Diseases associated with obesity continue to incur substantial costs and cause widespread human suffering. Moreover, substantial disparities in obesity rates exist among population groups, and in some cases these disparities are widening. Some groups and regions are continuing to experience increases in obesity rates, and the prevalence of severe obesity is continuing to rise. The Current State of Obesity Solutions in the United States is the summary of a workshop convened in January 2014 by the Institute of Medicine Roundtable on Obesity Solutions to foster an ongoing dialogue on critical and emerging implementation, policy, and research issues to accelerate progress in obesity prevention and care. Representatives of public health, health care, government, the food industry, education, philanthropy, the nonprofit sector, and academia met to discuss interventions designed to prevent and treat obesity. The workshop focused on early care and education, schools, worksites, health care institutions, communities and states, the federal government, and business and industry. For each of these groups, this report provides an overview of current efforts to improve nutrition, increase physical activity, and reduce disparities among populations.

This report issues a call for urgent action to combat the growing epidemic of obesity, which now affects developing and industrialized countries alike. Adopting a public health approach, the report responds to both the enormity of health problems associated with obesity and the notorious difficulty of treating this complex, multifactorial disease. With these problems in mind, the report aims to help policy-makers introduce strategies for prevention and management that have the greatest chance of success. The importance of prevention as the most sensible strategy in developing countries, where obesity coexists with undernutrition, is repeatedly emphasized. Recommended lines of action, which reflect the consensus reached by 25 leading authorities, are based on a critical review of current scientific knowledge about the causes of obesity in both individuals and populations. While all causes are considered, major attention is given to behavioural and societal changes that have increased the energy density of diets, overwhelmed sophisticated regulatory systems that control appetite and maintain energy balance, and reduced physical activity. Specific topics discussed range from the importance of fat content in the food supply as a cause of population-wide obesity, through misconceptions about obesity held by both the medical profession and the public, to strategies for dealing with the alarming prevalence of obesity in children. "... the volume is clearly written, and carries a wealth of summary information that is likely to be invaluable for anyone interested in the public health aspects of obesity and fatness, be they students, practitioner or researcher." - Journal of Biosocial Science
