Improving the Measurement of Late-Life Disability in Population Surveys summarizes a workshop organized to draw upon recent advances to improve the measurement of physical and cognitive disability in population surveys of the elderly population. The book questions whether or not the measures of activities of daily living and instrumental activities of daily living used in many population surveys are sufficient as the primary survey-based indicators of late-life disability. If not, should they be refined or should they be supplemented by other measures of disability in surveys? If yes, in what ways should disability measures be changed or modified to produce population estimates of late-life disability and to monitor trends? The book also discusses what further research is needed to advance this effort.

Over the past several decades, fertility rates have fallen substantially in low- and middle-income countries, and efforts to limit fertility, primarily through the implementation of family planning programs, have become increasingly widespread. Although there is a substantial scholarly literature on the determinants of contraceptive use and other measures to limit fertility and on the resulting differentials in fertility, relatively little is known about the role played by women''s empowerment as both a determinant and a consequence of fertility decline. In addition, there continues to be little consensus about the link between fertility decline and broader societal impacts, including economic development.

The National Academies of Sciences, Engineering, and Medicine convened a workshop, "Family Planning, Women''s Empowerment, and Population and Societal Impacts," in September 2020. This event brought together experts and stakeholders to discuss conceptual, methodological, and policy issues regarding the relationships among family planning, women''s empowerment, fertility decline, and population and societal impacts. The discussion was intended to inform research and policy focused on the issues of women''s roles and empowerment and on longstanding questions surrounding the determinants and consequences of fertility reduction behavior. This publication summarizes the presentations and discussion of the workshop.

Recent years have seen a growing tendency for social scientists to collect biological specimens such as blood, urine, and saliva as part of large-scale household surveys. By combining biological and social data, scientists are opening up new fields of inquiry and are able for the first time to address many new questions and connections. But including biospecimens in social surveys also adds a great deal of complexity and cost to the investigator''s task. Along with the usual concerns about informed consent, privacy issues, and the best ways to collect, store, and share data, researchers now face a variety of issues that are much less familiar or that appear in a new light. In particular, collecting and storing human biological materials for use in social science research raises additional legal, ethical, and social issues, as well as practical issues related to the storage, retrieval, and sharing of data. For example, acquiring biological data and linking them to social science databases requires a more complex informed consent process, the development of a biorepository, the establishment of data sharing policies, and the creation of a process for deciding how the data are going to be shared and used for secondary analysis—all of which add cost to a survey and require additional time and attention from the investigators. These issues also are likely to be unfamiliar to social scientists who have not worked with biological specimens in the past. Adding to the attraction of collecting biospecimens but also to the complexity of sharing and protecting the data is the fact that this is an era of incredibly rapid gains in our understanding of complex biological and physiological phenomena. Thus the tradeoffs between the risks and opportunities of expanding access to research data are constantly changing. Conducting Biosocial Surveys offers findings and recommendations concerning the best approaches to the collection, storage, use, and sharing of biospecimens gathered in social science surveys and the digital representations of biological data derived therefrom. It is aimed at researchers interested in carrying out such surveys, their institutions, and their funding agencies.

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.

The book looks carefully at the diverse populations encompassed by theterm "Hispanic," representing immigrants and their children and grandchildrenfrom nearly two dozen Spanish-speaking countries. It describes thetrajectory of the younger generations and established residents, and it projectslong-term trends in population aging, social disparities, and socialmobility that have shaped and will shape the Hispanic experience.

The challenges for young people making the transition to adulthood are greater today than ever before. Globalization, with its power to reach across national boundaries and into the smallest communities, carries with it the transformative power of new markets and new technology. At the same time, globalization brings with it new ideas and lifestyles that can conflict with traditional norms and values. And while the economic benefits are potentially enormous, the actual course of globalization has not been without its critics who charge that, to date, the gains have been very unevenly distributed, generating a new set of problems associated with rising inequality and social polarization. Regardless of how the globalization debate is resolved, it is clear that as broad global forces transform the world in which the next generation will live and work, the choices that today''s young people make or others make on their behalf will facilitate or constrain their success as adults. Traditional expectations regarding future employment prospects and life experiences are no longer valid.

Growing Up Global examines how the transition to adulthood is changing in developing countries, and what the implications of these changes might be for those responsible for designing youth policies and programs, in particular, those affecting adolescent reproductive health. The report sets forth a framework that identifies criteria for successful transitions in the context of contemporary global changes for five key adult roles: adult worker, citizen and community participant, spouse, parent, and household manager.

Selection processes play a role: selective migration, for instance, or selective survival to advanced ages. Health differentials originate early in life, possibly even before birth, and are affected by events and experiences throughout the life course. Differences in socioeconomic status, risk behavior, social relations, and health care all play a role. Separate chapters consider the contribution of such factors and the biopsychosocial mechanisms that link them to health. This volume provides the empirical evidence for the research agenda provided in the separate report of the Panel on Race, Ethnicity, and Health in Later Life.

As the population of older Americans grows, it is becoming more racially and ethnically diverse. Differences in health by racial and ethnic status could be increasingly consequential for health policy and programs. Such differences are not simply a matter of education or ability to pay for health care. For instance, Asian Americans and Hispanics appear to be in better health, on a number of indicators, than White Americans, despite, on average, lower socioeconomic status. The reasons are complex, including possible roles for such factors as selective migration, risk behaviors, exposure to various stressors, patient attitudes, and geographic variation in health care.

This volume, produced by a multidisciplinary panel, considers such possible explanations for racial and ethnic health differentials within an integrated framework. It provides a concise summary of available research and lays out a research agenda to address the many uncertainties in current knowledge. It recommends, for instance, looking at health differentials across the life course and deciphering the links between factors presumably producing differentials and biopsychosocial mechanisms that lead to impaired health.

Fertility and reproductive health issues more broadly have tended to be of low priority in humanitarian crises. Public attention is drawn by information concerning the magnitude of refugee flows, of death tolls, and of numbers of injuries. Reproductive health has been regarded as a longer term issue that could safely be put on the back burner during the crisis phase of an emergency, when issues of providing adequate food, clean water, and shelter, plus treating acute infectiousdiseases of crowding, take priority. This report reviews what evidence there is concerning the effects of humanitarian crisis on fertility, with a view to identifying common patterns that may exist across settings and be of value in guiding responses to future crises.

In May 2002 Timor Leste (East Timor) emerged as a new nation after centuries of foreign rule and decades of struggle for independence. Its birth was a painful one; a United Nations-brokered Popular Consultation in August 1999, in which an overwhelming majority of the people opted for independence, was followed by several weeks of vengeful violence, looting, and destruction by pro-Indonesia militias. It left the territory and all of its essential services devastated. In this context, the United Nations Transitional Administration in East Timor (UNTAET), with the country''s leaders and people and many other partners, set about restoring order and services, building a government structure, and preparing for independence. This paper summarizes the rehabilitation and development of the health sector from early 2000 to the end of 2001.

This report is concerned with reviewing psychosocial concepts in research related to humanitarian work, with particular emphasis on research related to children affected by prolonged violence and armed conflict.

Drawing from a wide variety of data sources, many of them previously inaccessible, Cities Transformed explores the implications of various urban contexts for marriage, fertility, health, schooling, and children''s lives. It should be of interest to all involved in city-level research, policy, planning, and investment decisions.

Admittedly, the world and the nature of forced migration have changed a great deal over the last two decades. The relevance of data accumulated during that time period can now be called into question. The roundtable and the Program on Forced Migration at the Mailman School of Public Health of Columbia University have commissioned a series of epidemiological reviews on priority public health problems for forced migrants that will update the state of knowledge. Malaria Control During Mass Population Movements and Natural Disasters— the first in the series, provides a basic overview of the state of knowledge of epidemiology of malaria and public health interventions and practices for controlling the disease in situations involving forced migration and conflict.

Hispanics are defined as people of Spanish-speaking origin from Latin America, the Caribbean, or Europe. Hispanics vary in terms of socioeconomic status, race, religion and/or more. A common occurrence among the Hispanics, however, are the emerging issues concerning their health.It is estimated that by 2050 Hispanics will make up more than 25% of the United States'' population. It is thus important that they have the resources to contribute maximally to American society. This can come about by first understanding and dealing with issues surrounding their health.

In hopes of examining these issues and as a part of its continuing commitment to promote a national dialogue on race and diversity in the United States, the National Academies organized an expert meeting on Emerging Issues in Hispanic Health on April 10, 2002.

Emerging Issues in Hispanic Health: Summary of a Workshop includes a review of key demographic data, such as population statistics, that characterize the Hispanic population in the United States; research on the socioeconomic, sociocultural, and behavioral determinants of health; effects of selective migration; the apparent epidemiological paradox : the relatively positive health outcomes observed in some Hispanic populations despite their relatively poor socioeconomic status or other types of disadvantage such as discrimination; and more.

The Roundtable on the Demography of Forced Migration was established by the Committee on Population of the National Research Council in 1999. The roundtable is composed of experts from academia, government, philanthropy, and international organizations. The roundtable''s purpose is to serve as an interdisciplinary, nonpartisan focal point for taking stock of what is known about demographic patterns in refugee situations, to apply this knowledge base to assist both policy makers and relief workers, and to stimulate new directions for innovation and scientific inquiry in this growing field of study.

Situations involving conflict and forced migration have become increasingly commonplace in today''s world. The need to understand the causes, consequences, and characteristics of these situations is creating a burgeoning field of research. But given the nature of complex emergency settings, traditional research guidelines may be inappropriate. The research and policy community has recognized this problem and has begun to address issues surrounding the ethics of doing research in emergency settings and among conflict-affected and displaced populations. The Roundtable on the Demography of Forced Migration, under the aegis of the Committee on Population of the National Research Council, held a workshop to examine some of these issues. This report to the roundtable summarizes the workshop presentations and discussion.

Longitudinal data collection and analysis are critical to social, demographic, and health research, policy, and practice. They are regularly used to address questions of demographic and health trends, policy and program evaluation, and causality. Panel studies, cohort studies, and longitudinal community studies have proved particularly important in developing countries that lack vital registration systems and comprehensive sources of information on the demographic and health situation of their populations. Research using data from such studies has led to scientific advances and improvements in the well-being of individuals in developing countries. Yet questions remain about the usefulness of these studies relative to their expense (and relative to cross-sectional surveys) and about the appropriate choice of alternative longitudinal strategies in different contexts.

For these reasons, the Committee on Population convened a workshop to examine the comparative strengths and weaknesses of various longitudinal approaches in addressing demographic and health questions in developing countries and to consider ways to strengthen longitudinal data collection and analysis. This report summarizes the discussion and opinions voiced at that workshop.

This volume is part of an effort to review what is known about the determinants of fertility transition in developing countries and to identify lessons that might lead to policies aimed at lowering fertility. It addresses the roles of diffusion processes, ideational change, social networks, and mass communications in changing behavior and values, especially as related to childbearing. A new body of empirical research is currently emerging from studies of social networks in Asia (Thailand, Taiwan, Korea), Latin America (Costa Rica), and Sub-Saharan Africa (Kenya, Malawi, Ghana). Given the potential significance of social interactions to the design of effective family planning programs in high-fertility settings, efforts to synthesize this emerging body of literature are clearly important.

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 populations—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.

In recent years the number of complex humanitarian emergencies around the world has been steadily increasing. War and political, ethnic, racial, and religious strife continually force people to migrate against their will. These forced migrants create a stream of new challenges for relief workers and policy makers. A better understanding of the characteristics of refugee populations and of the population dynamics of these situations is vital. Improved research and insights can enhance disaster management, refugee camp administration, and repatriation or resettlement programs.Forced Migration and Mortality examines mortality patterns in complex human- itarian emergencies, reviewing the state of knowledge, as well as how patterns may change in the new century. It contains four case studies of mortality in recent emergencies: Rwanda, North Korea, Kosovo, and Cambodia. Because refugees and internally displaced persons are likely to continue to be a significant humanitarian concern for many years, research in this field is critical. This is the first book to comprehensively explore forced migration and mortality and it provides useful material for researchers, policy makers, and relief workers.
