BMI readings were taken at six months and then at one year. The children were also assessed to see if the increased activity led to a reduction in sedentary behaviour or an increase in physical activity.
The increased level of exercise had little effect on the BMI or the activity behaviours of the children. However, it did help their motor and movement skills.
The researchers suggest that preventing obesity in early childhood may require change in the ‘wider environment’ rather than just at school and at home, and changes to diet are required.
