Epidemiology is fundamental to public health, providing the tools required to detect and quantify health problems and identify and evaluate solutions. Essential Epidemiology is a clear, engaging and methodological introduction to the subject. Now in its fifth edition, the text has been thoroughly updated. Its trademark clear and consistent pedagogical structure makes challenging topics accessible, while the local and international examples, including from the COVID-19 pandemic, encourage students to apply theory to real-world cases. Statistical analysis is explained simply, with more challenging concepts presented in optional advanced boxes. Each chapter includes information boxes, margin notes highlighting supplementary facts and question prompts to enhance learners' understanding. The end-of-chapter questions and accompanying guided solutions promote the consolidation of knowledge. Written by leading Australian academics and researchers, Essential Epidemiology remains a fundamental resource and reference text for students and public health practitioners alike.

Now in its fourth edition, Essential Epidemiology is an engaging and accessible introduction to the foundations of epidemiology. It addresses the study of infectious and chronic diseases, public health and clinical epidemiology, and the role of epidemiology in a range of health monitoring and research activities. Contemporary, historical and hypothetical examples enable students to engage with content, while mathematics is kept understandable with complex mathematics housed in optional material so the book remains accessible. With over ninety questions and answers to work through, this book is an essential resource for students, practitioners and anyone else who needs to interpret health data in their studies or work. Epidemiology's most important goal is to bring rigour to the collection, analysis and interpretation of health data to improve health on a global scale; Essential Epidemiology provides readers the tools to achieve that goal.

What do we do if different studies appear to give different answers? When applying research to questions for individual patients or for health policy, one of the challenges is interpreting such apparently conflicting research. A systematic review is a method to systematically identify relevant research, appraise its quality, and synthesize the results. The last two decades have seen increasing interest and developments in methods for doing high quality systematic reviews. Part I of this book provides a clear introduction to the concepts of reviewing, and lucidly describes the difficulties and traps to avoid. A unique feature of the book is its description, in Part II, of the different methods needed for different types of health care questions: frequency of disease, prognosis, diagnosis, risk, and management. As well as illustrative examples, there are exercises for each of the sections. This is essential reading for those interested in synthesizing health care research.
