Britain has the highest rate of obesity, and rates of illnesses, amongst teenagers in Europe, two charities have reported.

The Nuffield Trust and the Association for Young People’s Health studied health records from 14 high-income EU countries and found that 8.1% of teens in Britain were classified as clinically obese, with less than half that figure in France, Belgium and Germany, and with British teens having the highest rate of asthma and the greater likelihood of diabetes.
