Obesity rates continue to rise in OECD countries. The majority of inhabitants of OECD countries are overweight or obese, according to the OECD “Obesity Update” study. This study provides recent OECD data and analyses and shows that obesity levels in the majority of countries have continued to rise over the past five years, though at a slower pace than in the past. It is stable in United Kingdom, Korea, the US and Italy but has grown by 2-3% in Australia, Canada, Spain, France, Mexico and Switzerland. On average, one out of five children is overweight in OECD countries but this rate is as high as one in three in countries such as Greece, Italy, Slovenia and the US. However, the majority of countries have succeeded in stabilising or even slightly reducing child obesity rates, though this is not the case for adults. (IL)
