(·山西省運城市教學檢測)American children aren't the only couch potatoes with nearly one third of children globally spending three hours a day or more watching TV or on computers, according to the study of over 70,000 teens in 34 nations.
From Argentina to Zambia, Regina Guthold of the World Health Organization in Geneva and her colleagues found most children weren't getting enough exercise and that it made no difference if they lived in a rich or a poor country. “With regards to physical activities levels, we did not find much of a difference between poor and rich countries,” Guthold said. “Growing up in a poor country does not necessarily mean that kids get more physical activities.” The study was published in The Journal of Pediatrics, looking at 72,845 schoolchildren aged 13 to 15 from North and South America, Asia, Europe, and the Middle East. The children were surveyed between 2003 and 2007.
