In a recent research it was found that kids from middle-class families are more likely to be obese than those from poor families.
Researchers say the new findings contradict the conventional 'deprivation theory' which suggests childhood weight problems are linked to poverty.
By charting youngsters' obesity levels and where they lived, the team at Leeds Metropolitan University found that those in 'middle-affluent' areas of Leeds were more likely to be very overweight than those in very poor or very wealthy postcode areas, the Daily Mail reported.
Claire Griffiths, who led the study of 13,333 schoolchildren over three years, concluded that children living in the most deprived and most affluent areas of the city are at the lowest risk.
The research is published in the International Journal of Obesity.
