Analysis & Epidemiology

This course introduces the basic concepts of epidemiology and bio-statistics as applied to specific public health problems around the world. Emphasis is placed on the history and evolution of epidemiolo-gy and biostatistics, the principles and methods of epidemiologic investigation, appropriate summaries and displays of data, and the use of classical statistical approaches to describe the health of popu-lations. Topics include the dynamic behavior of disease; usage of rates, ratios and proportions; methods of direct and indirect adjust-ment, and clinical life table, which measures and describes the extent of disease problems. The global burden of disease will be analyzed based on computer models. Different epidemiologic study designs for investigating associations between risk factors and disease outcomes will be introduced, including criteria for causal inferences. The appli-cation of these disciplines in the areas of health services, screening, surveillance, and environmental policy are discussed, as well as legal and ethical issues in the context of epidemiology and biostatistics.
