The Oxford Textbook of Public Health 4e is unique in its presentation of the breadth and depth of the complex, dynamic field of public health. To accomplish this goal the textbook is divided into three volumes. The first volume presents the scope of public health, the second presents the methodologies and strategies and the third presents the practice of public health. This fourth edition has updated the many changes which have occurred in the field since the third edition was published, has expanded the scope to include issues of developing countries and presents the perspective of public leaders including the Director General of the World Health Organization on startegies to resolve these existing and anticipated public health problems. The textbook tackles such difficult issues as how to prioritize disparate public health problems, how to identify and implement cost effective startegies, the need for mobilizing the community through community involvement and the need for a comprehensive rather than an issue/disease oriented approach for the resolution of public health problems.The Oxford Textbook of Public Health is a comprehensive reference source for postgraduate students in public health, and provides insights into public health for those not primarily in public health but who need access to its expertise. The book is intended as a reference volume for use by public health professionals and academics. It should be included in every comprehensive library serving the health field and be on the shelf of every public health practitioner.
