Obese children are far less likely to finish school than peers of normal weight, according to European research that also highlights body image problems in kids as young as six.
And these problems are likely to become bigger and bigger as the waistlines of European children expand - led by Ireland with 27.5 per cent of under-fives classified as overweight, according to findings presented at a European Congress on Obesity in Prague.
Britain had the second-highest rate with 23.1 per cent, followed by Albania with 22 per cent and Georgia with 20 per cent, Bulgaria with 19.8 per cent and Spain with 18.4 per cent, said an analysis of data provided by 32 countries in the World Health Organization's 53-member Europe region.
Kazakhstan had the lowest rate at 0.6 per cent, Lithuania 5.1 per cent, conference host the Czech Republic 5.5 per cent, and Tajikistan six per cent.
People are classified overweight if they have a BMI (body weight index, a ratio of weight to height) of 25 and higher, and obese from a BMI of 30.
