The second edition of this best selling text is comprehensive introduction to principles applied in the practice of epidemiology in public health. Featuring the most current data and includes new problems, this revision incorporates modern ideas in epidemiological thinking that have been largely omitted in other textbooks. This edition will familiarize readers with terminology and key concepts in the design, analysis, and interpretation of epidemiological research, giving students the tools they need to critically evaluate scientific literature. Broad in scope, the text opens with five chapters covering the basic epidemiologic concepts and data sources. A major emphasis is placed on study design, with separate chapters devoted to each of the three main analytic designs: experimental, cohort, and case-control studies. Full chapters on bias, confounding, and random error, including the roll of statistics in epidemiology, ensure that students are well-equipped with the necessary information to interpret the results of epidemiologic studies. An entire chapter is also devoted to the concept of effect measure modification, an often-neglected topic in introductory textbooks. Up-to-date examples from the epidemiologic literature on diseases of public health importance are provided throughout the book.
