Fitness time bomb ticking for Chinese children

Youngsters in China are eating more and exercising less, and that's leaving them open to the risk of chronic illnesses, such as heart disease, high blood pressure and obesity, as Yang Wanli reports.

In June, as the end of the spring semester approached, the parents of hundreds of students at Tianjin Mofan Primary School were busy choosing the classes their children would take during a six-week summer camp.

Classes focusing on the arts, sports, English and written Chinese were among the favorites because most parents believe their children need to learn cast-iron skills early on if they are to gain an advantage in adult life.
