Physical activity does not alter children's BMI

A physical activity intervention designed to prevent obesity in children did not alter body mass index or sedentary behaviour, according to Reilley and colleagues (doi: 10.1136/bmj.38979.623773.55). The authors randomised 545 preschool children either to follow an exercise programme at nursery and at home or to no extra activity. Follow-up at six and 12 months showed that the exercise programme improved children's motor skills, which may affect future participation in sport, but had little effect on obesity in the short term.
