A study in the journal Preventive Medicine, shows that teenagers devote more time to sedentary behaviour (in front of a screen) at the weekend. This, said study author Juan P. Rey-López shows that "a sedentary lifestyle has become one of the major public health problems in developed countries".
Rey-López, a researcher at the University of Zaragoza (UNIZAR), said that "during the week, one-third of teenagers said the watched more than two hours of television per day. At weekends, this figure exceeds 60%".
"Our findings support the recommendation of the American Academy of Paediatrics not to put televisions in teenagers' bedrooms, in order to (theoretically) reduce the amount of time they spend watching the television", says Rey-López.
