: Lessons Learned from Implementing a Grocery Store Campaign in Michigan Communities at Risk for Neural Tube Defects.

Background: Sisters Together intended to develop and disseminate folic acid (FA) educational materials through a point-of-purchase program in low-income predominantly African American communities in Southeastern Michigan counties with high prevalence of neural tube defects (NTDs).

Methods: Guided by the Theory of Reasoned Action and the Consumer Information Processing Model, 17 supermarkets hosted displays, shelf-signs, and food tastings and tracked purchases of FA sources, alongside customer-intercept and store manager surveys, and observational logs.

Results: Stocking and signage were implemented with moderate-to-high fidelity, and food tastings with high reach and dose.
