Epidemiology, second edition, is a methodological and practical guide to conducting evidence-based quantitative research in all health sciences. With a multidisciplinary focus, it integrates a wealth of case studies and examples to demonstrate the application of theory to real-life research and draws from a broad spectrum of health disciplines.The book follows a two level ‘methods based’ approach which clearly differentiates between introductory knowledge that all students of epidemiology should be familiar with and beyond the basics information for the interested or more advanced reader. Each chapter includes tips, key definitions and critical thinking exercises to help readers engage with key concepts and extend their knowledge of epidemiological methodologies.
