More than 2 hours of screen time a day can damage children

A new Australian study on 2,570 New South Wales school children aged 11 to 15 has found that children who spend more than 2 hours a day in front of the television are less likely to be fit.

With concerns about the link between sedentary lifestyles and health, this study set out to examine the association between sedentary activities (including watching TV, DVDs, videos and recreational computer use) and cardio-respiratory endurance (CRE). Results showed that children who spent more than two hours a day in front of the television were less likely to be fit, with the effects more pronounced in girls than in boys.

The study, by Dr Louise Hardy of  the University of Sydney, is published in the February issue of the American Journal of Preventive Medicine.
