This report considers the biological and behavioral mechanisms that may underlie the pathogenicity of tobacco smoke. Many Surgeon General's reports have considered research findings on mechanisms in assessing the biological plausibility of associations observed in epidemiologic studies. Mechanisms of disease are important because they may provide plausibility, which is one of the guideline criteria for assessing evidence on causation. This report specifically reviews the evidence on the potential mechanisms by which smoking causes diseases and considers whether a mechanism is likely to be operative in the production of human disease by tobacco smoke. This evidence is relevant to understanding how smoking causes disease, to identifying those who may be particularly susceptible, and to assessing the potential risks of tobacco products.

Since 1980, childhood obesity rates have more than tripled in the United States. Recent data show that almost one-third of children over 2 years of age are already overweight or obese. While the prevalence of childhood obesity appears to have plateaued in recent years, the magnitude of the problem remains unsustainably high and represents an enormous public health concern. All options for addressing the childhood obesity epidemic must therefore be explored. In the United States, legal approaches have successfully reduced other threats to public health, such as the lack of passive restraints in automobiles and the use of tobacco. The question then arises of whether laws, regulations, and litigation can likewise be used to change practices and policies that contribute to obesity. On October 21, 2010, the Institute of Medicine (IOM) held a workshop to bring together stakeholders to discuss the current and future legal strategies aimed at combating childhood obesity. Legal Strategies in Childhood Obesity Prevention summarizes the proceedings of that workshop. The report examines the challenges involved in implementing public health initiatives by using legal strategies to elicit change. It also discusses circumstances in which legal strategies are needed and effective. This workshop was created only to explore the boundaries of potential legal approaches to address childhood obesity, and therefore, does not contain recommendations for the use of such approaches.

Obesity has reached epidemic proportions in countries like the United States. This book provides a comprehensive summary of obesity in America and around the world, discussing the causes and proposing ways to help stem the tide and to help those who are overweight. A highly useful and accessible resource for high school to undergraduate students as well as post-graduate level readers with an interest in health and nutrition, this updated second edition of Obesity: A Reference Handbook offers up-to-date answers to essential questions about obesity and connected societal and health care-related issues. A single-volume, go-to resource, this book addresses difficult questions such as whether obesity is a disease or a moral failing; what factors contribute to obesity; what the economic impacts of obesity are on the health care industry; if and how poverty is a contributor to obesity; how our society encourages obesity; and how changes can be made to improve our society's eating habits as a whole. It presents citations from individuals and peer-reviewed journals and review articles, providing a balance of information sourced from both professionals and informed lay commentators. Also included are dozens of biographies of individuals who have been important in studying, preventing, managing, or increasing awareness about obesity, such as Jared Fogle, longtime Subway sandwiches spokesperson; Kelly Brownell, who coined the phrase "toxic environment" to describe unhealthy food and exercise patterns; researcher Ethan Allen Sims, who examined the relationship between obesity and diabetes; and Oprah Winfrey, well-known celebrity who stated that if there were a pill to lose weight or a magic diet, she would have it.

This Open Access book highlights the ethical issues and dilemmas that arise in the practice of public health. It is also a tool to support instruction, debate, and dialogue regarding public health ethics. Although the practice of public health has always included consideration of ethical issues, the field of public health ethics as a discipline is a relatively new and emerging area. There are few practical training resources for public health practitioners, especially resources which include discussion of realistic cases which are likely to arise in the practice of public health. This work discusses these issues on a case to case basis and helps create awareness and understanding of the ethics of public health care. The main audience for the casebook is public health practitioners, including front-line workers, field epidemiology trainers and trainees, managers, planners, and decision makers who have an interest in learning about how to integrate ethical analysis into their day to day public health practice. The casebook is also useful to schools of public health and public health students as well as to academic ethicists who can use the book to teach public health ethics and distinguish it from clinical and research ethics.

Critical Reasoning and Science is an attempt to eliminate or at least diminish the feeling of estrangement that students may feel toward science. It is divided into three parts--a brief introduction to critical reasoning and science, a critical look at philosophical issues related to science, and a critical look at the practice of science. Overall, this work is unique in aim and functionality, as it is the first book to offer students a critical approach both to the philosophy and to the practice of science. Moreover, it aims to do so in a user-friendly manner by introducing material in short, digestible units (called "modules"). Each module has several history-of-science text boxes throughout as well as key terms, text questions, and text-box questions at its end. There are also ample practice exercises to test students on the material.
