問題詳情:
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 a study of over 70,000 teens in 34 nations. Regina Gutbold of the World Health Organization in Geneva and her colleagues found most children aren't getting enough exercise and it made no difference if they lived in a rich or a poor country. The study looked 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 2013.
Children who spent three or more hours a day watching TV, playing computer games, or chatting with friends—aside from time in school or time spent doing homework—were classified as sedentary (慣於久坐的人). The researchers found only one quarter of the boys and 15 percent of the girls were getting enough exercise according to these definitions.
Uruguay had the highest percentage of active boys, at 42 percent,while Zambia had the lowest, at 8 percent. Girls from India were the most active, with 37 percent meeting exercise recommendations (建議), while girls from Egypt were the least active, with just 4 percent getting enough exercise. Children in Myanmar were the least sedentary, with 13 percent of boys and 8 percent of girls classified as sedentary. The most sedentary nations were St. Lucia and the Cayman Islands,with 58 percent of boys and 64 percent of girls spending at least three hours a day in sedentary situations.
While the study didn't look at the reasons behind the lack of physical activity in various nations,Gutbold said that urbanization (城市化) could be a factor as well as access to cars and TVs.
