Issues of health and disease are central to human life, so an understanding of the science of epidemiology, the study of the patterns of disease and injury in human populations, is relevant to everyone. Many areas of study are directly concerned with epidemiological issues, including medicine and nursing, public policy, health administration, and the social and behavioral sciences. The Encyclopedia of Epidemiology presents state-of-the-art information from the field of epidemiology in a less technical and accessible style and format. With more than 600 entries, no single reference provides as comprehensive a resource in as focused and appropriate manner. The entries cover every major facet of epidemiology, from risk ratios to case-control studies to mediating and moderating variables, and much more. Relevant topics from related fields such as biostatistics and health economics are also included. Key Features - Presents a Reader's Guide to organize entries around themes or specific topics and easily guide users to areas of interest - Offers cross-referenced terms, brief listing of further readings, and stable website URLs following most entries - Provides appendices that include a general bibliography to build on "Further Readings," an annotated list of organizations relevant to epidemiology, the standard statistical tables used in epidemiology (t-distribution, F-table, normal [z] distribution, chi-square, etc.), and flow charts to aid researchers in selecting an appropriate study design This resource is a must-have for students, practitioners, researchers, and the informed public who want to know more about health and disease, and related topics.
