Sisters Together: 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. Purchases of black beans, spinach, orange juice, and supplements showed increases, although only a third of the women identified them as sources of FA. Only 21/122 women (17%) surveyed reported seeing the shelf-signs. CONCLUSIONS: Theory-driven, grocery store-centric interventions are effective strategies to address gaps in FA education, with the key behavior change mechanism appearing to be modeling "procedural knowledge."

Folic acid and the prevention of neural tube defects: A survey of awareness among Latina women of childbearing age residing in southeast Michigan.

Periconceptional intake of folic acid is known to reduce the risk for neural tube defects (NTDs). To inform southeast Michigan Latina women of childbearing age about the benefits of food and supplemental sources of the micronutrient in the prevention of NTDs, Spanish-English bilingual health educators carried out 20 education events in supermarkets and community organizations serving Latina women. One hundred and sixty Latina women ages 19 to 50 years indicated their current folic acid awareness and stated their future intentions regarding folic acid. Of 160 women surveyed, 114 (71%) had heard of folic acid, 84 (74%) knew that folic acid prevents birth defects, 63 (55%) knew the critical time to take folic acid, and 76 (67%) identified at least one source of folic acid. After participating in the education events, 136 women (85%) reported planning to eat more folate and/or folic acid-rich foods. Although general folic acid awareness is fairly high, health promotion efforts must be coordinated at community locations serving Latina women to share folic acid's specific protective effects in the prevention of NTDs, the critical timing of intake, and its food and supplement sources.
