This timely book introduces social aspects of the study of sexual health and their application to public health practice. The book addresses five key themes: Conceptual and theoretical aspects of sexual health, Sexual health outcomes of Risk and Vulnerability, Improving sexual health status and Measuring and assessing sexual health status. The authors consider each of these themes within their cultural and historical context and illustrate topics with international examples and case studies.Key features of the book include:O A spotlight on populations rather than individuals, and a focus on the prevention of ill health and promotion of well being. O A global perspective; the book makes the distinction between developing and developed countries, but recognises that inequalities are to be found within as well as between countries. O A view of sexual behaviour as socially learned rather than biologically given and so as amenable to change and intervention to improve sexual health status.O An emphasis on ways in which risk and vulnerability are products, not only of individual behaviours, but of the social context in which they are practiced.Written by authors with a wide range of experience, this book will be a valuable resource for public health practitioners and those studying and working in the area of sexual health. Understanding Public Health is an innovative series published by Open University Press in collaboration with the London School of Hygiene & Tropical Medicine.Series Editors: Ros Plowman and Nicki ThorogoodContributors: Sevgi O Aral, Chris Bonell, Helen Burchett, Joanna Busza, Martine Collumbien, Simon Forrest, Rebecca French, Claudia Garcia-Moreno, Anna Glasier, Jami Leichliter, Kirstin Mitchell, Will Nutland, Thomas Peterman, Elisabeth Pisani, Kaye Wellings, Meg Wiggins and Maria Zuurmond.
