A local health district in western Sydney surveys its primary schools and finds that one in three children aged 5 to 12 years is above the healthy weight range, against one in four across the state. Kilojoule labelling on menu boards is already mandatory for the state's large chain food outlets. The district's paediatric weight-management clinic sees about 200 children a year and has a fourteen-month waiting list; roughly 40,000 children live in the catchment. Funding exists for one new initiative. Which one of the following initiatives is most likely to reduce the number of children in this district who are above the healthy weight range?
