The purpose of this book is to explain and illustrate the key concepts which underpin the science of epidemiology and its applications to research, policy making, health service planning and health promotion. The book emphasizes theory, ideas, and epidemiological axioms. In doing this I hope to counter the mounting criticism that epidemiology is an atheoretical discipline. A concept is an idea, but the word is usually reserved for complex, or interrelated, ideas.A concept is the idea behind the word or phrase we use to describe something. This book, then, aims to explain the ideas underlying the language, principles, and basic methods in epidemiology. For example, the attributable risk and odds ratios are not considered merely as arithmetical equations or tools,but also in terms of the ideas underlying their calculation,applications,strengths,and limitations. This book is primarily written for postgraduates beginning courses on epidemiology anywhere in the world,for the concepts are the same everywhere.Only the examples will differ. The book may be of interest to public health and other epidemiological practitioners interested in revisiting the fundamental ideas of their discipline.Undergraduates who are keen on epidemiology may find it helpful in deepening their understanding generally,or while studying some topics in a little depth.Health professionals (including busy doctors) may find this material an interesting adjunct to their use of epidemiological techniques or data.Finally,health service managers and policy makers may find this book a source of insights into the world of epidemiology.
