Obesity and the Economics of Prevention : Fit not Fat Before 1980 rates were generally well below 10%. They have since doubled or tripled in many countries and in almost half of the OECD 50% or more of the population is overweight. A key risk factor for numerous chronic diseases obesity is a major public health concern. This book contributes to evidence based policy making by exploring multiple dimensions of the obesity problem. It examines the scale and characteristics of the epidemic the respective roles and influence of market forces and governments and the impact of interventions. It outlines an economic approach to the prevention of chronic diseases that provides novel insights relative to a more traditional public health approach. The analysis was undertaken by the OECD partly in collaboration with the World Health Organization. The main chapters are complemented by special contributions from health and obesity experts including Marc Suhrcke Tim Lobstein Donald Kenkel and Francesco Branca. “a valuable set of results and suggestions about the best preventive interventions to reduce the burden of obesity.” – Julio Frenk Dean Harvard School of Public Health “The positive message of this book is that the obesity epidemic can be successfully addressed.” – Ala Alwan Assistant Director General World Health Organization “innovative and well researched” – Martin McKee Professor London School of Hygiene & Tropical Medicine A timely valuable volume on a critical issue.
