Ethnoepidemiology, a new area of study in the field of cancer prevention and treatment, considers characteristic behavior patterns and physical and cultural factors that may be associated with some types of cancers. This exciting new field, which brings aspects of epidemiology, ethnology, ecology, virology, immunology, and molecular biology together in search of global cancer patterns, was the subject of a recent symposium of the Japanese Cancer Association. This book reports and expands upon the topics discussed at the symposium.
The digestive organs are the most frequent site of cancer in the world, accounting for approximately 30% of all malignant tumors. This prominent position has been present for many decades in spite of marked shifts in the freq uency of cancer of specific organs. The most remarkable shift has been the decrease in gastric cancer rates occurring concomitantly with an increase in colon cancer rates in most 'western' industrialized societies. Important exceptions to this rule, as well as other epidemiologic evidence, indicate that the opposite trends for gastric and colon cancers are not inevitable consequences of each other. Although genetic ally determined precancerous syndromes are well recognized, it is generally agreed that environmental factors play an overriding role in digestive cancer causation. The most obvious environmental factors seem to be the result of what we eat, drink, or smoke. Although the nutritional component of the diet is of unquestionable importance, the nonnutrient elements in our diet have also proven to be influential causative factors. Several studies have focused on the microenvironment at the level of the mucosa or the digestive organs as a micro cosmos where forces promoting and inhibiting carcinogenesis are operating for a prolonged period of time. Their interaction eventually determines the presence or absence of a malignant tumor. Our understanding of such modulating forces, hopefully, will someday allow us to modify the microenvironment in a favorable way and attain the goal of cancer prevention.
In their later years, Americans of different racial and ethnic backgrounds are not in equally good-or equally poor-health. There is wide variation, but on average older Whites are healthier than older Blacks and tend to outlive them. But Whites tend to be in poorer health than Hispanics and Asian Americans. This volume documents the differentials and considers possible explanations. 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.
Critical Medical Anthropology presents inspiring work from scholars doing and engaging with ethnographic research in or from Latin America, addressing themes that are central to contemporary Critical Medical Anthropology (CMA). This includes issues of inequality, embodiment of history, indigeneity, non-communicable diseases, gendered violence, migration, substance abuse, reproductive politics and judicialisation, as these relate to health. The collection of ethnographically informed research, including original theoretical contributions, reconsiders the broader relevance of CMA perspectives for addressing current global healthcare challenges from and of Latin America. It includes work spanning four countries in Latin America (Mexico, Brazil, Guatemala and Peru) as well as the trans-migratory contexts they connect and are defined by. By drawing on diverse social practices, it addresses challenges of central relevance to medical anthropology and global health, including reproduction and maternal health, sex work, rare and chronic diseases, the pharmaceutical industry and questions of agency, political economy, identity, ethnicity, and human rights.
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.
This book reveals unexamined assumptions and shows how sociocultural context influences measurement of disease.
Research on oncogenic viruses and related human cancers has advanced rapidly in the past decade. Most articles, however, focus on a specific oncogenic virus and cancer. There is consequently a need for a comprehensive, up-to-date monograph that offers broad and integrated knowledge. Viruses and Human Cancer – From Basic Science to Clinical Prevention is designed to meet this need by providing an advanced overview on the basic and clinical aspects of oncogenic viruses and the human cancers that they cause. Virology, virus-induced inflammation and tissue injuries, oncogenic mechanisms, epidemiology, and current and emerging preventive and therapeutic strategies are all discussed in detail. In addition, the book covers the individual aspects of seven oncogenic viruses, i.e., hepatitis B virus, hepatitis C virus, human papilloma virus, Epstein-Barr virus, human T-cell lymphotropic virus, Kaposi sarcoma-associated herpes virus, and Merkel cell polyomavirus, and the related human cancers.
Bringing the hard-to-quantify aspects of lived experience to analysis, and emphasizing what might be lost in interventions if cultural insights are absent, this book includes case studies from across the Asia and Pacific regions –Bangladesh, Malaysia, New Guinea, Indonesia, Thailand, South Korea, Australia, New Zealand, Tuvalu and the Cook Islands. When Culture Impacts Health offers conceptual, methodological and practical insights into understanding and successfully mediating cultural influences to address old and new public health issues including safe water delivery, leprosy, Attention Deficit Hyperactivity Disorder and body image. It contains useful methodological tools – how to map cultural consensus, measure wealth capital, conduct a cultural economy audit, for example. It provides approaches for discerning between ethnic and racial constructs and for conducting research among indigenous peoples. The book will be indispensible for culture and health researchers in all regions. - Discusses global application of case descriptions - Demonstrates how a cultural approach to health research enriches and informs our understanding of intractable public health problems - Covers methods and measurements applicable to a variety of cultural research approaches as well as actual research results - Case studies include medical anthropology, cultural epidemiology, cultural history and social medicine perspectives
As the drug abuse epidemic evolves, so do the tools needed to understand and treat it. Accordingly, Epidemiology of Drug Abuse takes the long view, cogently outlining what the book calls "the natural history of drug abuse" and redefining its complex phenomena to reflect our present-day knowledge. Twenty-six eminent contributors discuss the state and future of the field, balancing the practical concerns involved in gathering drug abuse data with the ethics of using the information. - Current thinking on pathways and etiology, as well as medical, psychological, and social sequelae of drug abuse - Proven, up-to-date methodologies for assessment - Challenges of gathering data from high-risk and other user populations - Sampling and application issues - Uses, sources, and limitations of treatment data - Analytical papers applying the methodologies to specific and global studies - The role of epidemiology studies in developing prevention strategies With this multifaceted approach to the subject, Epidemiology of Drug Abuse provides researchers and educators with a reference that sheds significant light on infrequently covered areas. In addition, its breadth and accessibility of coverage make it a teaching text suitable to courses in epidemiology, public health, and drug abuse.
Over the past two decades increasing interest has emerged in the contribu tions that the social sciences might make to the epidemiological study of patterns of health and disease. Several reasons can be cited for this increasing interest. Primary among these has been the rise of the chronic, non-infectious diseases as important causes of morbidity and mortality within Western populations during the 20th century. Generally speaking, the chronic, non infectious diseases are strongly influenced by lifestyle variables, which are themselves strongly influenced by social and cultural forces. The under standing of the effects of the behavioral factors in, say, hypertension, thus requires an understanding of the social and cultural factors which encourage obesity, a sedentary lifestyle, non-compliance with anti-hypertensive medica tions (or other prescribed regimens), and stress. Equally, there is a growing awareness that considerations of human behavior and its social and cultural determinants are important for understanding the distribution and control of infectious diseases. Related to this expansion of epidemiologic interest into the behavioral realm 'has been the development of etiological models which focus on the psychological, biological and socio-cultural characteristics of hosts, rather than exclusive concern with exposure to a particular agent or even behavioral risk. Also during this period advances in statistical and computing techniques have made accessible the ready testing of multivariate causal models, and so have encouraged the measurement of the effects of social and cultural factors on disease occurrence.
