The Gates Foundation and WHO recently funded a group of researchers to conduct worldwide comparative analyses of body mass index (BMI) using national health examination surveys. 199 countries and regions were studied. The trends were surprising:
- Since 1980 the global obesity rates have doubled.
- The USA had the highest BMIs in developed countries.
- Worldwide, approximately 1.5 billion people are overweight and of these 205M men and 297M women were obese.
Public health strategies and obesity prevention and treatment best practices need to be shared globally to stem the tide of this pandemic. The fall out from obesity also has huge consequences that result in an increase in high blood pressure and diabetes.
