Healthy lifestyle info fails to change kids' behaviour
The study, in 60 schools with more than 2200 children in South-West England, provided teacher training and special information for children and parents and compared outcomes after a year against a control group of children receiving standard teaching.
Accelerometers worn by the children showed no difference between the groups in time spent in vigorous activity or time spent in sedentary behaviour, although the intervention did reduce screen time. It failed to boost consumption of fruit and vegetables although snacks and sugary drink consumption was reduced.
