title: The nutrition transition: worldwide obesity dynamics and their determinants.
abstract: OBJECTIVE
  This paper explores the major changes in diet and physical activity patterns around the world and focuses on shifts in obesity.
  
  
  METHODS
  Review of results focusing on large-scale surveys and nationally representative studies of diet, activity, and obesity among adults and children.
  
  
  METHODS
  Youth and adults from a range of countries around the world.
  
  
  METHODS
  The International Obesity Task Force guidelines for defining overweight and obesity are used for youth and the body mass index > or =25 kg/m(2) and 30 cutoffs are used, respectively, for adults.
  
  
  RESULTS
  The nutrition transition patterns are examined from the time period termed the receding famine pattern to one dominated by nutrition-related noncommunicable diseases (NR-NCDs). The speed of dietary and activity pattern shifts is great, particularly in the developing world, resulting in major shifts in obesity on a worldwide basis. Data limitations force us to examine data on obesity trends in adults to provide a broader sense of changes in obesity over time, and then to examine the relatively fewer studies on youth. Specifically, this work provides a sense of change both in the United States, Europe, and the lower- and middle-income countries of Asia, Africa, the Middle East, and Latin America.
  
  
  CONCLUSIONS
  The paper shows that changes are occurring at great speed and at earlier stages of the economic and social development of each country. The burden of obesity is shifting towards the poor.
