In Switzerland a rapid increase in the total overweight population (BMI > or = 25) from 30.3% to 37.3% and in the obese segment (BMI > or = 30) from 5.4% to 8.1% was observed between 1992 and 2007. The objective of this study is to produce a projection until 2022 for the development of adult overweight and obesity in Switzerland based on four National Health Surveys conducted between 1992 and 2007. Based on the projection, these prevalence rates may be expected to stabilize until 2022 at the 2007 level. These results were compared with future projections estimated for France, UK, US and Australia using the same model.
