The scientific debate on longevity and its determinants is lively and involves researchers from different some people live longer than others is not an easy task. Variables that are shown to be significant for longer survival in certain populations are not always relevant to individuals of other populations. Recently, researchers have identified in Sardinia the Blue Zone (BZ), thus denominated due to the significant number of cases of centenarians recorded as well as a low sex ratio value. A village located in this area was selected for the carrying out of a more detailed analysis at individual level and socio-demographic determinants of longevity were examined. A family reconstructed database was created using a multi-source approach. Historical data was therefore used to study today's population, establishing a unique bridge between historical demography and the current level of longevity. The study focused on survival of newborns in the selected village during a period of 50 years – from 1866 to 1915 – and also took into consideration information on related family members. Each individual included in the database was followed from birth to death, as he/she went through marriage and family formation. Complete survival of all newborns was observed until the present. Based on careful review of the existing literature, the empirical model considered factors such as sex differential, the contribution of familial transmission both in terms of genes, biological, and shared environment, and the role played by environment operationalised considering early-life conditions. Concepts were organized into a life-course approach for survival analysis. The analysis of the data enabled to the estimation of mortality trajectories, which in turn confirmed the exceptional longevity of the population understudy and in particular of males. The investigation of differential survival among members of the same community brought to light the relevance of certain familial variables on survival, which are not exclusively genetic. The results achieved open the way to further studies.

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.

The average age of the world’s population is increasing at an unprecedented rate and this increase is changing the world. This “Silver tsunami” emphasizes the need to provide advanced training in epidemiology and increase the cadre of experts in the study of aging. This book is designed to summarize unique methodological issues relevant to the study of aging, biomarkers of aging and the biology/physiology of aging and in-depth discussions of the etiology and epidemiology of common geriatric syndromes and diseases. Contributing authors in the book represent many disciplines, not only epidemiology and clinical geriatrics, but also demography, health services, research, cardiovascular disease, diabetes, psychiatry, neurology, social services, musculoskeletal diseases and cancer. The aim of the book is to provide a broad multidisciplinary background for any student/researcher interested in aging. The material in the book is organized and comprehensive. It represents the most up-to-date information on the scientific issues in aging research written by academics who specialize in research and training in the broad field of aging. The structure and organization of the book reflects our course series in the Epidemiology of Aging starting with the broad issues of demography and methodology, and then addressing specific health conditions and geriatric conditions common to older persons.

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.

Epigenetics of Aging and Longevity provides an in-depth analysis of the epigenetic nature of aging and the role of epigenetic factors in mediating the link between early-life experiences and life-course health and aging. Chapters from leading international contributors explore the effect of adverse conditions in early-life that may result in disrupted epigenetic pathways, as well as the potential to correct these disrupted pathways via targeted therapeutic interventions. Intergenerational epigenetic inheritance, epigenetic drug discovery, and the role of epigenetic mechanisms in regulating specific age-associated illnesses—including cancer and cardiovascular, metabolic, and neurodegenerative diseases—are explored in detail. This book will help researchers in genomic medicine, epigenetics, and biogerontology better understand the epigenetic determinants of aging and longevity, and ultimately aid in developing therapeutics to extend the human life-span and treat age-related disease. - Offers a comprehensive overview of the epigenetic nature of aging, as well as the impact of epigenetic factors on longevity and regulating age-related disease - Provides readers with clinical and epidemiological evidence for the role of epigenetic mechanisms in mediating the link between early-life experiences, life-course health and aging trajectory - Applies current knowledge of epigenetic regulatory pathways towards developing therapeutic interventions for age-related diseases and extending the human lifespan

Featuring extensive references, updated for this paperback edition, Longevity, Senescence, and the Genome constitutes a landmark contribution to biomedicine and the evolutionary biology of aging. To enhance gerontology's focus on human age-related dysfunctions, Caleb E. Finch provides a comparative review of all the phyla of organisms, broadening gerontology to intersect with behavioral, developmental, evolutionary, and molecular biology. By comparing species that have different developmental and life spans, Finch proposes an original typology of senescence from rapid to gradual to negligible, and he provides the first multiphyletic calculations of mortality rate constants.

In 1950 men and women in the United States had a combined life expectancy of 68.9 years, the 12th highest life expectancy at birth in the world. Today, life expectancy is up to 79.2 years, yet the country is now 28th on the list, behind the United Kingdom, Korea, Canada, and France, among others. The United States does have higher rates of infant mortality and violent deaths than in other developed countries, but these factors do not fully account for the country's relatively poor ranking in life expectancy. International Differences in Mortality at Older Ages: Dimensions and Sources examines patterns in international differences in life expectancy above age 50 and assesses the evidence and arguments that have been advanced to explain the poor position of the United States relative to other countries. The papers in this deeply researched volume identify gaps in measurement, data, theory, and research design and pinpoint areas for future high-priority research in this area. In addition to examining the differences in mortality around the world, the papers in International Differences in Mortality at Older Ages look at health factors and life-style choices commonly believed to contribute to the observed international differences in life expectancy. They also identify strategic opportunities for health-related interventions. This book offers a wide variety of disciplinary and scholarly perspectives to the study of mortality, and it offers in-depth analyses that can serve health professionals, policy makers, statisticians, and researchers.

How do some people avoid the slowing down, deteriorating, and weakening that plagues many of their peers decades earlier? Are they just lucky? Or do they know something the rest of us don’t? Is it possible to grow older without getting sicker? What if you could look and feel fifty through your eighties and nineties? Founder of the Institute for Aging Research at the Albert Einstein College of Medicine and one of the leading pioneers of longevity research, Dr. Nir Barzilai’s life’s work is tackling the challenges of aging to delay and prevent the onset of all age-related diseases including “the big four”: diabetes, cancer, heart disease, and Alzheimer’s. One of Dr. Barzilai’s most fascinating studies features volunteers that include 750 SuperAgers—individuals who maintain active lives well into their nineties and even beyond—and, more importantly, who reached that ripe old age never having experienced cardiovascular disease, cancer, diabetes, or cognitive decline. In Age Later, Dr. Barzilai reveals the secrets his team has unlocked about SuperAgers and the scientific discoveries that show we can mimic some of their natural resistance to the aging process. This eye-opening and inspirational book will help you think of aging not as a certainty, but as a phenomenon—like many other diseases and misfortunes—that can be targeted, improved, and even cured.
