Healthy aging is defined as the process of developing and maintaining the functional ability that enables well-being in older age. As population aging accelerates rapidly worldwide, healthy aging has become a major public health challenge. However, in later life, several metabolic diseases such as diabetes and hypertension and their complications (cardiovascular and renal diseases et al.) impose significant barriers to healthy aging. These conditions are influenced by various metabolic risk factors, such as smoking, high-calorie diet, and obesity. Moreover, these risk factors can also affect the aging process itself, by disrupting the balance of metabolic regulation in the body. Therefore, understanding the complex interactions between aging and metabolic diseases is essential for improving public health outcomes in older populations. This Research Topic aims to explore the links between metabolic risk factors, chronic and metabolic diseases, and healthy aging. We wish to unveil evidence on how to prevent, treat, and manage metabolic risk factors and diseases in older adults, in order to offer recommendations for future research and policy interventions toward healthy aging and public health.

Trends such as shifting dietary patterns and an increasingly sedentary lifestyle combined with smoking and alcohol consumption are major risk factors for noncommunicable chronic diseases such as obesity, diabetes, cardiovascular diseases such as hypertension and stroke, cancer dental diseases and osteoporosis. This report reviews the scientific evidence on the effects of diet, nutrition and physical activity on chronic diseases and makes recommendations for public health policies and programmes. Issues considered include the macro-economic implications of public health on agriculture and the global supply and demand for fresh and processed foods.

Young adulthood - ages approximately 18 to 26 - is a critical period of development with long-lasting implications for a person's economic security, health and well-being. Young adults are key contributors to the nation's workforce and military services and, since many are parents, to the healthy development of the next generation. Although 'millennials' have received attention in the popular media in recent years, young adults are too rarely treated as a distinct population in policy, programs, and research. Instead, they are often grouped with adolescents or, more often, with all adults. Currently, the nation is experiencing economic restructuring, widening inequality, a rapidly rising ratio of older adults, and an increasingly diverse population. The possible transformative effects of these features make focus on young adults especially important. A systematic approach to understanding and responding to the unique circumstances and needs of today's young adults can help to pave the way to a more productive and equitable tomorrow for young adults in particular and our society at large. Investing in The Health and Well-Being of Young Adults describes what is meant by the term young adulthood, who young adults are, what they are doing, and what they need. This study recommends actions that nonprofit programs and federal, state, and local agencies can take to help young adults make a successful transition from adolescence to adulthood. According to this report, young adults should be considered as a separate group from adolescents and older adults. Investing in The Health and Well-Being of Young Adults makes the case that increased efforts to improve high school and college graduate rates and education and workforce development systems that are more closely tied to high-demand economic sectors will help this age group achieve greater opportunity and success. The report also discusses the health status of young adults and makes recommendations to develop evidence-based practices for young adults for medical and behavioral health, including preventions. What happens during the young adult years has profound implications for the rest of the life course, and the stability and progress of society at large depends on how any cohort of young adults fares as a whole. Investing in The Health and Well-Being of Young Adults will provide a roadmap to improving outcomes for this age group as they transition from adolescence to adulthood.

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.

Promotes the recognition, treatment, and prevention of conditions of overweight and obesity in the United States.

Epidemiology and Demography in Public Health provides practical guidance on planning and implementing surveillance and investigation of disease and disease outbreaks. Exploring contributing factors to the dynamics of disease transmission and the identification of population risks, it also includes a discussion of ehtics in epidemiology and demography including important issues of privacy vs. public safety. With a chapter on H1N1 and Bird flu, this book will be important for students and professionals in public health and epidemiology. - Focuses on the techniques of surveillance and investigation of disease - Includes biostatistics and analysis techniques - Explores the ethics of disease studies - Includes chapter discussing H1N1 and Bird Flu

The U.S. population of older adults is predicted to grow rapidly as "baby boomers" (those born between 1946 and 1964) begin to reach 65 years of age. Simultaneously, advancements in medical care and improved awareness of healthy lifestyles have led to longer life expectancies. The Census Bureau projects that the population of Americans 65 years of age and older will rise from approximately 40 million in 2010 to 55 million in 2020, a 36 percent increase. Furthermore, older adults are choosing to live independently in the community setting rather than residing in an institutional environment. Furthermore, the types of services needed by this population are shifting due to changes in their health issues. Older adults have historically been viewed as underweight and frail; however, over the past decade there has been an increase in the number of obese older persons. Obesity in older adults is not only associated with medical comorbidities such as diabetes; it is also a major risk factor for functional decline and homebound status. The baby boomers have a greater prevalence of obesity than any of their historic counterparts, and projections forecast an aging population with even greater chronic disease burden and disability. In light of the increasing numbers of older adults choosing to live independently rather than in nursing homes, and the important role nutrition can play in healthy aging, the Institute of Medicine (IOM) convened a public workshop to illuminate issues related to community-based delivery of nutrition services for older adults and to identify nutrition interventions and model programs. Nutrition and Healthy Aging in the Community summarizes the presentations and discussions prepared from the workshop transcript and slides. This report examines nutrition-related issues of concern experienced by older adults in the community including nutrition screening, food insecurity, sarcopenic obesity, dietary patterns for older adults, and economic issues. This report explores transitional care as individuals move from acute, subacute, or chronic care settings to the community, and provides models of transitional care in the community. This report also provides examples of successful intervention models in the community setting, and covers the discussion of research gaps in knowledge about nutrition interventions and services for older adults in the community.

Cardiovascular, respiratory, and related conditions cause more than 40 percent of all deaths globally, and their substantial burden is rising, particularly in low- and middle-income countries (LMICs). Their burden extends well beyond health effects to include significant economic and societal consequences. Most of these conditions are related, share risk factors, and have common control measures at the clinical, population, and policy levels. Lives can be extended and improved when these diseases are prevented, detected, and managed. This volume summarizes current knowledge and presents evidence-based interventions that are effective, cost-effective, and scalable in LMICs.

Aging is a process that encompasses virtually all aspects of life. Because the speed of population aging is accelerating, and because the data needed to study the aging process are complex and expensive to obtain, it is imperative that countries coordinate their research efforts to reap the most benefits from this important information. Preparing for an Aging World looks at the behavioral and socioeconomic aspects of aging, and focuses on work, retirement, and pensions; wealth and savings behavior; health and disability; intergenerational transfers; and concepts of well-being. It makes recommendations for a collection of new, cross-national data on aging populationsâ€"data that will allow nations to develop policies and programs for addressing the major shifts in population age structure now occurring. These efforts, if made internationally, would advance our understanding of the aging process around the world.
