This title is directed primarily towards health care professionals outside of the United States. Designed to help readers understand and evaluate the relationship between exercise, immune function and infection risk, this book presents evidence for the "J-shaped" relationship between exercise load and infection risk. It also describes the components of the human immune system and key functions that protect the body from disease, the impact of acute and chronic psychological stress on immune function, and practical guidelines for minimizing the risk of immunodepression and infection in athletes. Further chapters explore different ways of measuring immune function, as well as the effects of heavy training on innate and specific (acquired) immunity, exercise in environmental extremes, and nutrition. Connections between exercise, infection risk, and immune function in special populations (elderly, obese, diabetic and HIV patients) are also addressed. Authored by a team of highly experienced experts. The "J-shaped" relationship between exercise load and infection risk is described, backed by current research and evidence. Components of the immune system and normal immune function are explained in detail, as well as methods for measuring immune function. The impact of acute and chronic psychological stress on immune function is presented, along with suggestions for minimizing the risk of immunodepression and infection in athletes. The effects of heavy training, exercise in environmental extremes, and nutrition are discussed with regard to their impact on innate and specific (acquired) immunity. Immune function in special populations (elderly, obese, diabetic and HIV patients) is also addressed, exploring links between exercise and infection risk in these groups. Evidence-based coverage includes a list of references in each chapter, as well as suggestions for further reading that direct readers to important texts and review articles. Information is presented in an easily accessible format, following a logical progression of material. LEach chapter begins with a list of learning objectives and ends with a list of key points to reinforce learning. A glossary at the end of the book defines all key terms and abbreviations.
Every aspect of immune function and host defense is dependent upon a proper supply and balance of nutrients. Severe malnutrition can cause significant alteration in immune response, but even subclinical deficits may be associated with an impaired immune response, and an increased risk of infection. Infectious diseases have accounted for more off-duty days during major wars than combat wounds or nonbattle injuries. Combined stressors may reduce the normal ability of soldiers to resist pathogens, increase their susceptibility to biological warfare agents, and reduce the effectiveness of vaccines intended to protect them. There is also a concern with the inappropriate use of dietary supplements. This book, one of a series, examines the impact of various types of stressors and the role of specific dietary nutrients in maintaining immune function of military personnel in the field. It reviews the impact of compromised nutrition status on immune function; the interaction of health, exercise, and stress (both physical and psychological) in immune function; and the role of nutritional supplements and newer biotechnology methods reported to enhance immune function. The first part of the book contains the committee's workshop summary and evaluation of ongoing research by Army scientists on immune status in special forces troops, responses to the Army's questions, conclusions, and recommendations. The rest of the book contains papers contributed by workshop speakers, grouped under such broad topics as an introduction to what is known about immune function, the assessment of immune function, the effect of nutrition, and the relation between the many and varied stresses encountered by military personnel and their effect on health.
In the United States, some populations suffer from far greater disparities in health than others. Those disparities are caused not only by fundamental differences in health status across segments of the population, but also because of inequities in factors that impact health status, so-called determinants of health. Only part of an individual's health status depends on his or her behavior and choice; community-wide problems like poverty, unemployment, poor education, inadequate housing, poor public transportation, interpersonal violence, and decaying neighborhoods also contribute to health inequities, as well as the historic and ongoing interplay of structures, policies, and norms that shape lives. When these factors are not optimal in a community, it does not mean they are intractable: such inequities can be mitigated by social policies that can shape health in powerful ways. Communities in Action: Pathways to Health Equity seeks to delineate the causes of and the solutions to health inequities in the United States. This report focuses on what communities can do to promote health equity, what actions are needed by the many and varied stakeholders that are part of communities or support them, as well as the root causes and structural barriers that need to be overcome.

This book brings together articles on the overarching theme of how the environment shapes the immune system. The immune system is commonly assumed to respond to harmful pathogens such as bacteria and viruses. However, harmless bacteria, chemicals, stress, normal food and other factors can also trigger, shape or interfere with the immune system, often producing adverse effects. Yet, it is also becoming increasingly accepted that some of these interactions are physiological and necessary for a healthy immune system. Examples of negative effects include the immunosuppressive effects of UV irradiation, or the immunotoxic effects of man-made chemicals such as polycyclic aromatic hydrocarbons. Autoimmunity or allergies can be the adverse consequences of interaction between the immune system and chemical compounds such as drugs. Positive effects can come from natural exposure levels to bacteria, healthy life-style or the diet. There is a great need to understand how communication between the environment and the immune system works. This book addresses this need. It covers environmental factors (such as bacteria, sun exposure), human factors (such as age, exercise or stress), and important man-made factors (such as air pollution). A chapter on human rights complements the scientific chapters. The book is intended for immunologists, toxicologists and researchers who want to know how the immune system works and is triggered, as well as for medical doctors in environmental medicine and the general public interested in immunology.
Physical inactivity is a key determinant of health across the lifespan. A lack of activity increases the risk of heart disease, colon and breast cancer, diabetes mellitus, hypertension, osteoporosis, anxiety and depression and others diseases. Emerging literature has suggested that in terms of mortality, the global population health burden of physical inactivity approaches that of cigarette smoking. The prevalence and substantial disease risk associated with physical inactivity has been described as a pandemic. The prevalence, health impact, and evidence of changeability all have resulted in calls for action to increase physical activity across the lifespan. In response to the need to find ways to make physical activity a health priority for youth, the Institute of Medicine's Committee on Physical Activity and Physical Education in the School Environment was formed. Its purpose was to review the current status of physical activity and physical education in the school environment, including before, during, and after school, and examine the influences of physical activity and physical education on the short and long term physical, cognitive and brain, and psychosocial health and development of children and adolescents. Educating the Student Body makes recommendations about approaches for strengthening and improving programs and policies for physical activity and physical education in the school environment. This report lays out a set of guiding principles to guide its work on these tasks. These included: recognizing the benefits of instilling life-long physical activity habits in children; the value of using systems thinking in improving physical activity and physical education in the school environment; the recognition of current disparities in opportunities and the need to achieve equity in physical activity and physical education; the importance of considering all types of school environments; the need to take into consideration the diversity of students as recommendations are developed. This report will be of interest to local and national policymakers, school officials, teachers, and the education community, researchers, professional organizations, and parents interested in physical activity, physical education, and health for school-aged children and adolescents.
This book demonstrates that nutrients play a direct role as co-factors and regulators of the immune system. The book also shows that modulating the immune response with nutrients can provide a fundamental approach to preventive medicine.;Containing nearly 2300 bibliographic citations as well as illustrative figures, tables, and micrographs, this book is designed to be of interest to clinical immunologists, immunology and vitamin researchers, nutrition specialists, paediatricians, neonatologists, and upper-level undergraduate, graduate, and medical school students in these disciplines.
People's desire to understand the environments in which they live is a natural one. People spend most of their time in spaces and structures designed, built, and managed by humans, and it is estimated that people in developed countries now spend 90 percent of their lives indoors. As people move from homes to workplaces, traveling in cars and on transit systems, microorganisms are continually with and around them. The human-associated microbes that are shed, along with the human behaviors that affect their transport and removal, make significant contributions to the diversity of the indoor microbiome. The characteristics of "healthy" indoor environments cannot yet be defined, nor do microbial, clinical, and building researchers yet understand how to modify features of indoor environmentsâ€"such as building ventilation systems and the chemistry of building materialsâ€"in ways that would have predictable impacts on microbial communities to promote health and prevent disease. The factors that affect the environments within buildings, the ways in which building characteristics influence the composition and function of indoor microbial communities, and the ways in which these microbial communities relate to human health and well-being are extraordinarily complex and can be explored only as a dynamic, interconnected ecosystem by engaging the fields of microbial biology and ecology, chemistry, building science, and human physiology. This report reviews what is known about the intersection of these disciplines, and how new tools may facilitate advances in understanding the ecosystem of built environments, indoor microbiomes, and effects on human health and well-being. It offers a research agenda to generate the information needed so that stakeholders with an interest in understanding the impacts of built environments will be able to make more informed decisions.
Children's health has clearly improved over the past several decades. Significant and positive gains have been made in lowering rates of infant mortality and morbidity from infectious diseases and accidental causes, improved access to health care, and reduction in the effects of environmental contaminants such as lead. Yet major questions still remain about how to assess the status of children's health, what factors should be monitored, and the appropriate measurement tools that should be used. Children's Health, the Nation's Wealth: Assessing and Improving Child Health provides a detailed examination of the information about children's health that is needed to help policy makers and program providers at the federal, state, and local levels. In order to improve children's health-and, thus, the health of future generations-it is critical to have data that can be used to assess both current conditions and possible future threats to children's health. This compelling book describes what is known about the health of children and what is needed to expand the knowledge. By strategically improving the health of children, we ensure healthier future generations to come.
