According to another survey tracking the health of 36,962 college and high school students in Beijing, about 40 percent of them did not get enough exercise, 42.1 percent spent more than two hours in front of the computer, and 37.4 percent regularly skipped breakfast.

Public health authorities believed that the results may shed some light on prime culprits in the obesity epidemic.

Authorities also said they are rolling out programs to promote healthier eating and allocate more time for physical activities in schools to prevent kids from becoming overweight.
