Taken from Morris JN, Uses of Epidemiology.4. Epidemiology is “the study of how disease is distributed in populations and the factors that influence or determine this distribution.” 1 Clinical epidemiology “denotes the application of epidemiologic methods to questions relevant to patient care” and “provides a highly useful set of principles and methods for the design and conduct of quantitative clinical research.” 2 PowerPoint Version Cdc-ppt [PPT-880KB]. The parameter of interest may be a disease rate, the prevalence of an exposure, or more often some measure of the association between an exposure and disease. Rates are typically expressed as a measure of the frequency with which an event occurs in a defined population in a defined time (eg, the number of foodborne Salmonella infections per 100,000 people annually in the USA). Define epidemiology and biostatistics, in terms of their relationship to each other, and discuss their roles in collecting, describing, and evaluating data The person: characteristics—age, sex, race, and occupation—of descriptive epidemiology used to characterize the populations at risk. Epidemiology consists of research methods and specific strategies for counting and calculating the occurrence and risk of disease. Establishing a case definition is an imperative step in quantifying the magnitude of disease in a population. In addition to the adenoma to carcinoma sequence, colorectal carcinogenesis can occur via the serrated pathway. Therefore, epidemiological studies of drug use employ these methods and statistical measures to study the occurrence and distribution of drug use … ... Student learns to propose research questions and hypotheses, review the literature, and use basic epidemiology and statistical techniques to answer the research questions posed. » Lecture 1: Biostatistics and Epidemiology within the Paradigm of Public Health (Diener-West) Describe the role quantitative methods play in addressing public health questions . epidemiology [ep″ĭ-de″me-ol´o-je] the science concerned with the study of the factors determining and influencing the frequency and distribution of disease, injury, and other health-related events and their causes in a defined human population for the purpose of establishing programs to prevent and control their development and spread.
