Physical activity clearly is associated with decreased risk of many chronic diseases, as well as with longer life. Utilizing modern epidemiologic methods, studies of physical activity and health have been conducted since the 1940s. However physical inactivity did not gain widespread acknowledgement as a major risk factor for poor health until 1992, when the American Heart Association recognized it as a risk factor for heart disease, on par with risk factors such as smoking. This text includes chapters describing the associations between physical activity and major diseases. With a major emphasis on the methods underpinning studies that can be conducted to elucidate these associations, this book is an important guide for those performing the informative epidemiologic studies needed to reduce the increasing number of people diagnosed with chronic disease due to inactivity.

"Physical Activity Epidemiology, Second Edition," provides a comprehensive discussion of current population-level studies showing the influence of physical activity on disease. Updated with extensive new research collected in the eight years since the previous edition, the second edition adds the expertise of respected epidemiologist I-Min Lee. To assist readers in understanding the public health significance of physical activity, Dishman, Heath, and Lee present a detailed review of research findings and what those findings suggest regarding the relationship between physical activity and a variety of health risks.

The second edition of this groundbreaking text has been exhaustively updated to reflect the wealth of new research published in this fast-moving field of study. With more than 100 pages of additional content, the text also offers more detailed coverage of all-cause and coronary heart disease mortality, expanded coverage of pathophysiology and biological plausibility, new information on physical activity among various racial-ethnic populations, and the effects of physical activity on cognitive function, dementia, and HIV/AIDS. More than 250 tables and figures, twice the number found in the previous edition, highlight the latest epidemiological information in an easy-to-understand visual format.

"Physical Activity Epidemiology, Second Edition," assists readers in understanding how leisure-time physical activity can enhance people's quantity and quality of life by summarizing the available knowledge, detailing the methods used to obtain it, considering its implications for public health, and outlining the important questions that remain. Readers will find comprehensive discussion of these topics:

- Evidence that physical activity protects against the development of coronary heart disease and stroke and premature death from all causes

- Population-based studies and clinical experiments providing evidence that physical activity and exercise play a role in the primary and secondary prevention of mild hypertension, dyslipidemia, and obesity

- Contemporary epidemiologic evidence that physical activity reduces the risk of type 2 diabetes and osteoporosis and protects against the development of breast and colon cancers, some inflammatory diseases, depression, and anxiety disorders

- Considerations in the promotion of a safe, physically active lifestyle among all segments of the population

"Physical Activity Epidemiology, Second Edition," will engage and challenge students by examining the state of current research in all of its variation and even ambiguity. The text details the methodology and findings of classic and contemporary studies and then helps students begin to analyze the results. Special Strength of the Evidence sections found at the end of most chapters summarize the findings to determine the extent to which correlation and causation can be proven. Chapter objectives, chapter summaries, and sidebars in each chapter assist students in focusing on the key points of study, and an extensive glossary with detailed definitions provides a handy reference for review. Instructors will find a new image bank in this edition to enhance their class lecture materials.

"Physical Activity Epidemiology, Second Edition," offers students, sport and exercise scientists, health and fitness professionals, and public health administrators a comprehensive presentation of significant studies, how these studies contribute to understanding the relationship between activity and disease prevention, and how this information can be used in leading individuals, communities, and global society toward increased health and longevity.

Physical Activity Epidemiology, Third Edition, provides a discussion of current studies showing the influence of physical activity on disease. Updated with extensive new content in alignment with the 2018 Physical Activity Guidelines Advisory Committee Scientific Report, the third edition benefits from the expertise of authors Rod Dishman, Gregory Heath, Michael Schmidt, and I-Min Lee. These authors offer insight gained from their professional experiences, which include leadership roles within the Centers for Disease Control and Prevention, contributions to the 2008 Physical Activity Guidelines for Americans, and a combined 1,000 peer-reviewed articles in high-impact journals across each of their disciplines. Physical Activity Epidemiology, Third Edition, explores how physical activity can enhance quality of life. The text summarizes the available knowledge, examines the methods used to obtain these findings, considers the implications for public health, and outlines the important questions that remain. Readers will find comprehensive discussions of these topics: Part I introduces physical activity epidemiology and provides an extensive background in research methods as well as physical activity measurement and surveillance. Part II focuses on the evidence that physical activity protects against premature death from all causes and inhibits the development of coronary heart disease and stroke. Part III offers population-based studies and clinical experiments providing evidence that physical activity plays a role in the prevention of hypertension, dyslipidemia, and obesity. Part IV compiles the latest data on two chronic diseases that are increasing in prevalence worldwide: type 2 diabetes and osteoporosis. Part V describes the evidence that physical activity is associated with reduced risks of certain cancers and explores the use of immunotherapy in cancer treatment. Part VI addresses mental health and the promotion of a safe, physically active lifestyle among all segments of the population. The third edition of this text offers expanded coverage of the measurement of sedentary behavior; the effects of physical activity on osteoporosis and bone health, cancers, and inflammatory diseases; and the potential of exercise to complement immunotherapy in cancer treatment. More than 200 tables and figures highlight information in an easy-to-understand visual format. Physical Activity Epidemiology, Third Edition, examines the methodology and findings of classic and contemporary studies and then helps students analyze the results. The special Strength of the Evidence sections summarize the findings to determine the extent to which correlation and causation can be proven. Chapter objectives, chapter summaries, sidebars, and a glossary assist students in finding key information. Instructors will find a test package, image bank, and downloadable learning activities to assist with student comprehension. Physical Activity Epidemiology, Third Edition, offers a comprehensive presentation of significant studies, discusses how these studies contribute to understanding the relationship between activity and disease prevention, and explores how this information can be used in leading global society toward increased health and longevity.
