Comprehensive in its coverage and suitable for graduate or upper-division undergraduate students in a wide range of health-related disciplines, this latest offering by William A. Oleckno is a full-scale, pedagogically rich introduction to fundamental ideas and procedures in epidemiology. The text covers the major concepts, principles, methods, and applications of both conventional and modern epidemiology using clear language and frequent examples to illustrate important points and facilitate understanding. While Oleckno provides thorough treatment of the more customary aspects of conventional and modern epidemiology, he also introduces several important design and analytical issues that are only rarely approached in fundamental epidemiology textbooks.
