The intervention is a theory-based multi-channel communications campaign based on qualitative research with the target population: children in grades three and four in public schools in Eastern Massachusetts and their caregivers. Schools were randomized to one of three conditions: (1) a campaign that includes healthy eating and eco-friendly messages; (2) a campaign that includes healthy eating messages only; and (3) a delayed healthy eating eco-friendly campaign after serving as a control group. Foods brought from home and the packaging associated with those foods will be assessed at baseline and at the end of the school year using a photographic technique.
