Issues in Public Health, second edition is a text for those who want to answer the questions, 'What is public health?' and 'Why is it important?'. This book looks at the foundations of public health, its historical evolution, the themes that underpin public health, the increasing importance of globalization and the most important causes of avoidable disease and injury, including environmental factors, tobacco and other personal lifestyle factors, nutrition and infectious disease. Part of the Understanding Public Health series, Issues in Public Health is an introductory text for higher education students, primarily at MSC level but studying public health in depth for the first time. The second edition includes two new chapters on the expanding role of public health and the impact of climate change on health. It also features expanded examples of the impact of globalization on higher and lower income countries and explores the tension between the population approach and the personal behaviour change model of health promotion.
