Aging populations are generating both challenges and opportunities for societies around the globe. Increases in longevity and improvements in health raise many questions. What steps can be taken to optimize physical and cognitive health and productivity across the life span? How will older people finance their retirement and health care? What will be the macroeconomic implications of an aging population? How will communities be shaped by the shift in age structure? What global interconnections will affect how each society handles the aging of its population? To address these questions, the National Academies organized a symposium, summarized in the present volume, to determine how best to contribute to an evidence-based dialogue on population aging that will shape policies and programs. Presentations in the fields of biology, public health, medicine, informatics, macroeconomics, finance, urban planning, and engineering approached the challenges of aging from many different angles. The presenters reviewed the current state of knowledge in their respective fields, identifying areas of consensus and controversy and delineating the priority questions for further research and policy development.

The role of public health in the planning, coordination, and delivery of health promotion and disease prevention services to older people living outside of institutional settings. Selected by Choice Magazine as an Outstanding Academic Title Current issues in the public health arena have challenged the system to broaden its traditional focus on infectious disease to include chronic disease as well. As this change in emphasis takes place, professionals must be prepared to address the special chronic health concerns of older people living in the community. This textbook meets the training needs of those professionals. Public Health and Aging examines the role of public health in the planning, coordination, and delivery of health promotion and disease prevention services to older people living outside of institutional settings. Here, experts in the areas of health care policy and care of aged persons analyze the scientific basis for the practice of public health in an increasingly aging society. Reviewing a wide range of the social, cultural, financial, and environmental factors that influence the health experiences of older population groups, the authors delve into the epidemiology of age-related chronic illnesses, program development, methodological issues, data collection and analysis, strategies for intervention, and ethics. From outlines for community-based program planning and development to discussions about the future challenges for health care systems and services, this book is an ideal reference for gerontology, public policy, and public health professionals and professionals in training.
As the United States and the rest of the world face the unprecedented challenge of aging populations, this volume draws together for the first time state-of-the-art work from the emerging field of the demography of aging. The nine chapters, written by experts from a variety of disciplines, highlight data sources and research approaches, results, and proposed strategies on a topic with major policy implications for labor forces, economic well-being, health care, and the need for social and family supports.
The United States is in the midst of a major demographic shift. In the coming decades, people aged 65 and over will make up an increasingly large percentage of the population: The ratio of people aged 65+ to people aged 20-64 will rise by 80%. This shift is happening for two reasons: people are living longer, and many couples are choosing to have fewer children and to have those children somewhat later in life. The resulting demographic shift will present the nation with economic challenges, both to absorb the costs and to leverage the benefits of an aging population. Aging and the Macroeconomy: Long-Term Implications of an Older Population presents the fundamental factors driving the aging of the U.S. population, as well as its societal implications and likely long-term macroeconomic effects in a global context. The report finds that, while population aging does not pose an insurmountable challenge to the nation, it is imperative that sensible policies are implemented soon to allow companies and households to respond. It offers four practical approaches for preparing resources to support the future consumption of households and for adapting to the new economic landscape.
In sub-Saharan Africa, older people make up a relatively small fraction of the total population and are supported primarily by family and other kinship networks. They have traditionally been viewed as repositories of information and wisdom, and are critical pillars of the community but as the HIV/AIDS pandemic destroys family systems, the elderly increasingly have to deal with the loss of their own support while absorbing the additional responsibilities of caring for their orphaned grandchildren. Aging in Sub-Saharan Africa explores ways to promote U.S. research interests and to augment the sub-Saharan governments' capacity to address the many challenges posed by population aging. Five major themes are explored in the book such as the need for a basic definition of "older person," the need for national governments to invest more in basic research and the coordination of data collection across countries, and the need for improved dialogue between local researchers and policy makers. This book makes three major recommendations: 1) the development of a research agenda 2) enhancing research opportunity and implementation and 3) the translation of research findings.
Does a longer life mean a healthier life? The number of adults over 65 in the United States is growing, but many may not be aware that they are at greater risk from foodborne diseases and their nutritional needs change as they age. The IOM's Food Forum held a workshop October 29-30, 2009, to discuss food safety and nutrition concerns for older adults.
Traditionally, the natural sciences have been divided into two branches: the biological sciences and the physical sciences. Today, an increasing number of scientists are addressing problems lying at the intersection of the two. These problems are most often biological in nature, but examining them through the lens of the physical sciences can yield exciting results and opportunities. For example, one area producing effective cross-discipline research opportunities centers on the dynamics of systems. Equilibrium, multistability, and stochastic behavior-concepts familiar to physicists and chemists-are now being used to tackle issues associated with living systems such as adaptation, feedback, and emergent behavior. Research at the Intersection of the Physical and Life Sciences discusses how some of the most important scientific and societal challenges can be addressed, at least in part, by collaborative research that lies at the intersection of traditional disciplines, including biology, chemistry, and physics. This book describes how some of the mysteries of the biological world are being addressed using tools and techniques developed in the physical sciences, and identifies five areas of potentially transformative research. Work in these areas would have significant impact in both research and society at large by expanding our understanding of the physical world and by revealing new opportunities for advancing public health, technology, and stewardship of the environment. This book recommends several ways to accelerate such cross-discipline research. Many of these recommendations are directed toward those administering the faculties and resources of our great research institutions-and the stewards of our research funders, making this book an excellent resource for academic and research institutions, scientists, universities, and federal and private funding agencies.
Compared to other regions, Europe and Central Asia are by far the oldest. Moreover, population aging is set to accelerate further over the coming decades as large segments turn old. Additionally, some countries such as Russia and certain Eastern European countries are facing a shrinkage of their population. Against this backdrop, this report investigates what stands in the way of societies reaping the full benefits of increased longevity--that is, longer lives and potentially prolonged payoffs from human capital--and what can help to mitigate the possible negative impacts of a smaller and older workforce. Beginning with a focus on demographic trends, the report puts the rapid decline in fertility and contrasting migration trends in the region in a historical perspective and looks forward to the varying paths that population change may follow in the region. Next, it examines the evidence on the likely impact of demographic change on growth and savings, the labor force, firm and economy-wide innovation, poverty and inequality, and intergenerational solidarity. Finally, the report goes beyond diagnostics and puts an emphasis on what we know regarding successful policy interventions, presenting evidence on what has and has not worked in the past.--Publisher description.
Social isolation and loneliness are serious yet underappreciated public health risks that affect a significant portion of the older adult population. Approximately one-quarter of community-dwelling Americans aged 65 and older are considered to be socially isolated, and a significant proportion of adults in the United States report feeling lonely. People who are 50 years of age or older are more likely to experience many of the risk factors that can cause or exacerbate social isolation or loneliness, such as living alone, the loss of family or friends, chronic illness, and sensory impairments. Over a life course, social isolation and loneliness may be episodic or chronic, depending upon an individual's circumstances and perceptions. A substantial body of evidence demonstrates that social isolation presents a major risk for premature mortality, comparable to other risk factors such as high blood pressure, smoking, or obesity. As older adults are particularly high-volume and high-frequency users of the health care system, there is an opportunity for health care professionals to identify, prevent, and mitigate the adverse health impacts of social isolation and loneliness in older adults. Social Isolation and Loneliness in Older Adults summarizes the evidence base and explores how social isolation and loneliness affect health and quality of life in adults aged 50 and older, particularly among low income, underserved, and vulnerable populations. This report makes recommendations specifically for clinical settings of health care to identify those who suffer the resultant negative health impacts of social isolation and loneliness and target interventions to improve their social conditions. Social Isolation and Loneliness in Older Adults considers clinical tools and methodologies, better education and training for the health care workforce, and dissemination and implementation that will be important for translating research into practice, especially as the evidence base for effective interventions continues to flourish.
