Video games have been named as a main cause of obesity in the young by a World Health Organization study.
One-third of children living in different parts of the world are obese, said the study published in the Journal of Pediatrics.
It reported over 70,000 teenagers from 34 different nations are overweight or obese. It called a sedentary lifestyle - 'spending three hours or more per day watching TV, playing computer games, or chatting with friends' - is the main reason behind the figure.
Only 25 percent of the boys and 15 percent of the girls get enough exercise, said the report.
"With regards to physical activity levels, we did not find much of a difference between poor and rich countries," said WHO official Regina Guthold, adding that "growing up in a poor country does not necessarily mean that kids get more physical activity."
The report comes after a Government-commissioned reportfound video games were 'sexualising children'.
Be warned, then: Mario can make your offspring a corpulent, Jordan wannabe. Yeah, right...
