Book Description
Two thousand years ago, the average life expectancy from birth to death of a Roman citizen, an individual better off than most people at that time, was about 22 years (wars, infectious diseases, trauma, etc.). This progressively increased to about 47 years in the U.S. and most European countries by 1900. Today, the average life expectancy in the U.S. is 78 years (women about five years more than men). However, unless the obesity pandemic is reversed and lifestyles improved, the average life expectancy will likely decrease significantly. conversely, if our lifestyles improve, the average life expectancy could reach 85 or more years. Growing older does not necessarily mean growing sicker. Thus, "don't just add years to your life, add life to your years" (Hans Selve). Indeed, of the 15 major causes of death in the U.S., 65-70% are lifestyle-related. In this book, the following documented topics that are associated with diseases and mortality are discussed in detail: theories of aging; diseases and mortality associated with obesity, physical inactivity and poor nutrition; psychological stress (anxiety, depression); addiction (alcohol, tobacco, drugs); violence (suicide, homicide); food-borne and infectious diseases (viral, bacterial, parasitic); and various other conditions (air pollution, asbestosis, trace metals).

Book Description
Recent studies have indicated that epigenetic processes may play a major role in both cellular and organismal aging. These epigenetic processes include not only DNA methylation and histone modifications, but also extend to many other epigenetic mediators such as the polycomb group proteins, chromosomal position effects, and noncoding RNA. The topics of this book range from fundamental changes in DNA methylation in aging to the most recent research on intervention into epigenetic modifications to modulate the aging process. The major topics of epigenetics and aging covered in this book are: 1) DNA methylation and histone modifications in aging; 2) Other epigenetic processes and aging; 3) Impact of epigenetics on aging; 4) Epigenetics of age-related diseases; 5) Epigenetic interventions and aging: and 6) Future directions in epigenetic aging research. The most studied of epigenetic processes, DNA methylation, has been associated with cellular aging and aging of organisms for many years. It is now apparent that both global and gene-specific alterations occur not only in DNA methylation during aging, but also in several histone alterations. Many epigenetic alterations can have an impact on aging processes such as stem cell aging, control of telomerase, modifications of telomeres, and epigenetic drift can impact the aging process as evident in the recent studies of aging monozygotic twins. Numerous age-related diseases are affected by epigenetic mechanisms. For example, recent studies have shown that DNA methylation is altered in Alzheimer’s disease and autoimmunity. Other prevalent diseases that have been associated with age-related epigenetic changes include cancer and diabetes. Paternal age and epigenetic changes appear to have an effect on schizophrenia and epigenetic silencing has been associated with several of the progeroid syndromes of premature aging. Moreover, the impact of dietary or drug intervention into epigenetic processes as they affect normal aging or age-related diseases is becoming increasingly feasible.

Book Description
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.

Book Description
How do communities protect and improve the health of their populations? Health care is part of the answer but so are environmental protections, social and educational services, adequate nutrition, and a host of other activities. With concern over funding constraints, making sure such activities are efficient and effective is becoming a high priority. Improving Health in the Community explains how population-based performance monitoring programs can help communities point their efforts in the right direction. Within a broad definition of community health, the committee addresses factors surrounding the implementation of performance monitoring and explores the "why" and "how to" of establishing mechanisms to monitor the performance of those who can influence community health. The book offers a policy framework, applies a multidimensional model of the determinants of health, and provides sets of prototype performance indicators for specific health issues. Improving Health in the Community presents an attainable vision of a process that can achieve community-wide health benefits.

Book Description
The Director of this study, Abraham Kagan, has comprehensively summarized the design and main finndings of the study in this book. The Honolulu Heart Program compared and contrasted ethnic Japanese men living in different cultural environments--Honolulu and mainland Japan--assessed their relative risk factors. The study supported many of the existing views on risk factors but also showed suprising trends. One of the trends shows moderate alcohol consumption is a preventative factor. In recent years the risk factors for cardiovascular diseases have become common knowledge. The recently completed Honolulu Heart Program is the largest targeted study to evaluate scientifically such risk factors.

Book Description
The proportion of elderly people continues to increase in the western world-nearly a quarter of the population will be over 65 years by the year 2050. Since aging is accompanied by an increase in diseases and by a deterioration in well-being, finding solutions to these social, medical and psychological problems is necessarily a major goal for society. Scientists and medical practitioners are therefore faced with the urgent task of increasing basic knowledge of the biological processes that cause aging. More resources must be put into this research in order to achieve better understanding of the cellular mechanisms that underlie the differences in life span between species and to answer the difficult questions of why some individuals age more quickly than others, and why some develop liver problems, some have heart problems, and others brain problems. The results of such a wide program of research will provide important information about the causes of many life-threatening and/ or debilitating diseases of old age; it will help find ways to prevent some of the ailments that result from aging, and it may well lead to discoveries enabling the prolongation of human life.

Book Description
“An outstanding contribution to the study of aging” from a psychiatrist and professor at Harvard Medical School (Publishers Weekly). In an unprecedented series of studies, Harvard Medical School has followed 824 subjects—men and women, some rich, some poor—from their teens to old age. Harvard's George Vaillant now uses these studies—the most complete ever done anywhere in the world—and the subjects' individual histories to illustrate the factors involved in reaching a happy, healthy old age. He explains precisely why some people turn out to be more resilient than others, the complicated effects of marriage and divorce, negative personality changes, and how to live a more fulfilling, satisfying and rewarding life in the later years. He shows why a person's background has less to do with their eventual happiness than the specific lifestyle choices they make. And he offers step-by-step advice about how each of us can change our lifestyles and age successfully. Sure to be debated on talk shows and in living rooms, Vaillant's definitive and inspiring book is the new classic account of how we live and how we can live better. It will receive massive media attention, and with good reason: we have never seen anything like it, and what it has to tell us will make all the difference in the world. “A respected researcher. . . . offers suggestions for successful and happy aging. Highly recommended.” —Library Journal “Astonishing observations. . . . [Aging Well] provides the only available longitudinal assessment of the factors that will permit us to age well.” —New England Journal of Medicine “Perceptive, understanding, and often tinged with delightful humor.” —Booklist

Book Description
During the last 25 years, life expectancy at age 50 in the United States has been rising, but at a slower pace than in many other high-income countries, such as Japan and Australia. This difference is particularly notable given that the United States spends more on health care than any other nation. Concerned about this divergence, the National Institute on Aging asked the National Research Council to examine evidence on its possible causes. According to Explaining Divergent Levels of Longevity in High-Income Countries, the nation's history of heavy smoking is a major reason why lifespans in the United States fall short of those in many other high-income nations. Evidence suggests that current obesity levels play a substantial part as well. The book reports that lack of universal access to health care in the U.S. also has increased mortality and reduced life expectancy, though this is a less significant factor for those over age 65 because of Medicare access. For the main causes of death at older ages-cancer and cardiovascular disease-available indicators do not suggest that the U.S. health care system is failing to prevent deaths that would be averted elsewhere. In fact, cancer detection and survival appear to be better in the U.S. than in most other high-income nations, and survival rates following a heart attack also are favorable. Explaining Divergent Levels of Longevity in High-Income Countries identifies many gaps in research. For instance, while lung cancer deaths are a reliable marker of the damage from smoking, no clear-cut marker exists for obesity, physical inactivity, social integration, or other risks considered in this book. Moreover, evaluation of these risk factors is based on observational studies, which-unlike randomized controlled trials-are subject to many biases.

Book Description
"Among the most influential models in contemporary behavioral science, self-determination theory (SDT) offers a broad framework for understanding the factors that promote human motivation and psychological flourishing. In this authoritative work, SDT cofounders Richard M. Ryan and Edward L. Deci systematically review the theory's conceptual underpinnings, empirical evidence base, and practical applications across the lifespan. Ryan and Deci demonstrate that supporting people's basic needs for competence, relatedness, and autonomy is critically important for virtually all aspects of individual and societal functioning."--Jacket.
