Some weight-loss camps, which are rare in China just a few years ago, have sprouted（萌芽） in Beijing, Qingdao, Shenzhen, and other cities. Today about 15 percent of adults, or 200 million Chinese, are reportedly overweight. Of these, 90 million—about 7 percent—are obese（极肥胖的）.
Experts say the obesity epidemic is spreading to children, though more slowly than in adults. The trend, they say, will have a huge impact on the health of China's citizens and economy. "We're seeing a very large proportion（比例） of children and adolescents who are quite heavy and aren't moving much," said Barry Popkin, a nutrition professor. Popkin carries out an ongoing health-and-nutrition survey of 16,000 households in China. He says more kids today are overeating and putting on weight "quite quickly." In just ten years China's childhood obesity rate has doubled, with the greatest gains coming in urban(城市的) areas. "In big cities it's a big problem."
Some experts blame the extra fat on a range of factors, many of them tied to China's rapidly changing economy and culture. The diets of Chinese adults and children are far higher in calorie-laden meats, fish, eggs, dairy products, fats, and sugars than ever before. __________, kids—especially city dwellers—are more sedentary(久坐的) today and spend more time indoors in front of homework, television, computer games, and the Internet.
Shuwen Ng, a health economist, says that kids in China now have pocket money, and they spend a portion of it on junk food. Ng adds that advertising and peer groups influence kids' food choices. Certain foods, such as new candies or fast food, have attractive features.
China's childhood obesity rate still lags that of the United States, where some 15 percent of kids are said to be obese. But the long-term effects are equally serious.
