Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Eligible schools utilising an online lunch ordering system will be randomised to receive the following intervention to their online canteen menu. All fruit and vegetable items (i.e. fresh, frozen, tinned, dried) will be grouped together in a single category by a dietitian. The category will be listed multiple times within the online menu, and will be moved to more prominent positions within the menu i.e. the first and last category of foods displayed on the online menu. Intervention schools will be required to maintain these menu changes throughout the 4-week duration of the intervention.

Intervention Delivery and Duration: For schools allocated to receive the intervention, the re-designed menu will be uploaded at one time point and will remain in place for 4 weeks.

Intervention Fidelity: The provider of the online canteen service will send through a mid-intervention report listing any changes that have been made to the online menu since the launch of the intervention, in order to determine intervention fidelity. Any deviations from the original intervention positioning will be corrected.

Location: The online intervention will be delivered via the online lunch ordering system. Users of the system (primary school children and their parents) will access the online menu (to make their selection and pay) via their mobile devices (phone or tablet) or their computer.
