Description : This book focuses on the key issues of design and analysis in studies which aim to relate measures of nutritional exposure to disease outcome. The first section discusses how to identify the appropriate measures of exposure and outcome in order to formulate a clear research hypothesis, including the question of power and sample size. This is followed by a detailed discussion of how to measure the exposures and outcomes with a desired degree of accuracy. Particular emphasis is placed on the identification of measurement error and confounding factors, and how to cope with their influence on the observed relationships. The final section addresses the problem of design and interpretation that arise in epidemiological studies - ecological, case control, cohort, and experimental - which include measures of nutritional exposure. The need for this book arises because of the complexity of nutritional exposures. By learning how to identify relevant measures of nutritional exposure and measure them correctly in epidemiological studies, we improve our ability to assess the role of nutrition in disease etiology....

Description : In examining the relationship between nutritional exposure and disease aetiology, the importance of a carefully considered experimental design cannot be overstated. A sound experimental design involves the formulation of a clear research hypothesis and the identification of appropriate measures of exposure and outcome. It is essential that these variables can be measured with a minimum of error, whilst taking into account the effects of chance and bias, and being aware of the risk of confounding variables. The first edition of Design Concepts in Nutritional Epidemiology presented a throrough guide to research methods in nutritional epidemiology. Since publication of the 1st edition, we now have a much better understanding of the characteristics of nutritional exposure that need to be measured in order to answer questions about diet-disease relationships. The 2nd edition has been extensively revised to include the most up-to-date methods of researching this relationship. Included are new chapters on qualitative and sociological measures, anthropometric measures, gene-nutrient interactions, and cross-sectional studies. Design Concepts in Nutritional Epidemiology will be an essential text for nutritionists and epidemiologists, helping them in their quest to improve the quality of information upon which important public health decisions are made....

Description : The thoroughly revised and updated Third Edition of the acclaimed Modern Epidemiology reflects both the conceptual development of this evolving science and the increasingly focal role that epidemiology plays in dealing with public health and medical problems. Coauthored by three leading epidemiologists, with sixteen additional contributors, this Third Edition is the most comprehensive and cohesive text on the principles and methods of epidemiologic research. The book covers a broad range of concepts and methods, such as basic measures of disease frequency and associations, study design, field methods, threats to validity, and assessing precision. It also covers advanced topics in data analysis such as Bayesian analysis, bias analysis, and hierarchical regression. Chapters examine specific areas of research such as disease surveillance, ecologic studies, social epidemiology, infectious disease epidemiology, genetic and molecular epidemiology, nutritional epidemiology, environmental epidemiology, reproductive epidemiology, and clinical epidemiology....

Description : Epidemiology is a population science that underpins health improvement and health care, by exploring and establishing the pattern, frequency, trends, and causes of a disease. Concepts of Epidemiology comprehensively describes the application of core epidemiological concepts and principles to readers interested in population health research, policy making, health service planning, health promotion, and clinical care. The book provides an overview of study designs and practical framework for the geographical analysis of diseases, including accounting for error and bias within studies. It discusses the ways in which epidemiological data are presented, explains the distinction between association and causation, as well as relative and absolute risks, and considers the theoretical and ethical basis of epidemiology both in the past and the future. This new edition places even greater emphasis on interactive learning. Each chapter includes learning objectives, theoretical and numerical exercises, questions and answers, a summary of the key points, and exemplar panels to illustrate the concepts and methods under consideration. Written in an accessible and engaging style, with a specialized glossary to explain and de\'1fne technical terminology, Concepts of Epidemiology is ideal for postgraduate students in epidemiology, public health, and health policy. It is also perfect for clinicians, undergraduate students and researchers in medicine, nursing and other health disciplines who wish to improve their understanding of fundamental epidemiological concepts....

Description : Understanding Epidemiology: Concepts, Skills, and Application teaches undergraduate students the skills required to think critically about public health challenges. The text takes an interdisciplinary approach to solving epidemiological problems that mirrors epidemiology in practice. Students are exposed to the foundational principles of epidemiology and practice applying these principles using multiple methods. Students learn to read and use public health and health science literature to design appropriate epidemiological studies, ultimately becoming intelligent consumers of health information able to make distinctions and connections between public health practice and clinical medicine. The second edition includes additional case studies and examples designed to help undergraduates understand the concepts and applications of the science of epidemiology. New chapters on public health prevention and outbreak investigations, and material on emerging issues in public health have been added to illustrate the impact epidemiology has on the fields of public health and clinical medicine. Each chapter includes a set of comprehension questions to ensure that students understand the key concepts that are presented. There are also challenge questions at the end of each chapter that provide students with application opportunities. Specifically written for undergraduate students, the book does not assume a working knowledge of biostatistics. Understanding Epidemiology can be used in introductory epidemiology courses, as well as in public health study design and health sciences research methods courses....
