We have known of the rising obesity and overweight crisis for some time, and researchers have done numerous studies that show the more physically active children are, the more likely they are to have a healthy weight (as measured by body mass index, BMI) and to stay active and maintain a healthy weight through adulthood.

This has led to the development of interventions, or programs that deliberately aim to increase levels of physical activity in children by providing them with extra exercise sessions, for instance in school time or afterwards.

But so far, studies of those interventions show they are not successful in improving children's BMI.

For their review, the authors searched recognized databases and references lists for peer-reviewed journal studies that matched their requirements. They had to be examining interventions designed to increase activity levels in children aged 16 and under that lasted for at least four weeks, and measured results objectively, using accelerometers.

30 randomized controlled trials that took place between January 1990 and March 2012 matched these requirements. All the studies were matched on age, ethnicity, and socio-economic status, and the results were adjusted for gender and activity levels at the start of the intervention period.

Eight of the studies had included only overweight or obese children, while the rest included children from all BMI ranges.

The researchers assessed the effect of interventions on total physical activity and time spent on moderate or vigorous physical activity.
