Since 1980 the average body mass index (BMI) has increased in all regions, but now middle income countries have caught up with high income countries. The highest levels of obesity in the world are found in Pacific Island nations.
The research, supported by the Bill and Melinda Gates Foundation and the World Health Organization, shows that systolic blood pressure is currently highest in low income and middle income countries.
