Active rural kids facing battle of the bulge
Dietary imbalance, lack of nutritional education are fueling obesity risk
Limits of 'move more'
Public health messaging in China has long emphasized physical activity. School posters urge students to "strengthen the body". Morning calisthenics remain mandatory in many campuses.
Anthropologist Susan Greenhalgh, professor emerita at Harvard University who specializes in the intersections of science, governance, and society in contemporary China, has traced how this emphasis on exercise became central to China's obesity discourse.
In her research, she has documented how beverage companies supported scientific exchanges and exercise-focused school programs beginning in the late 1990s.
"Coca-Cola succeeded in redirecting China's obesity science and policy to emphasize physical activity," Greenhalgh wrote in an analysis of institutional ties.
Framing obesity primarily as a matter of "energy balance" — calories in versus calories out — aligns neatly with corporate interests.
The new rural study does not examine corporate influence. But its findings complicate the assumption that promoting activity alone can neutralize dietary risk.
At Wanyue Middle School, a physical education teacher surnamed Chen said the school strictly follows national activity guidelines.
"We make sure students exercise every day," he said. "Running, stretching and basketball."
Asked about sugary beverages, he sighed. "We can advise them not to drink too much," he said. "But outside school, we cannot control everything."
Some public health scholars argue that broader measures — clearer labeling, marketing restrictions or taxes on sugar-sweetened beverages — may eventually be necessary.
As the final bell rang, Qian Wei joined his classmates for another round of drills. He moved quickly across the court, laughing, shoulders loose with adolescent energy.
Nothing about him suggested illness. Yet according to national screening data, his waist measurement signals elevated metabolic risk.
"I'll try to drink less soda," he said. "But after running, I really feel like I need it, especially in summer."
