Minneapolis, Minnesota Customers
Minneapolis, Minnesota has a policy in place whereby minimum quantities and varieties of healthy food are required for all licensed food stores. The policy is our "intervention" condition.
This local policy change (i.e., the Minneapolis Staple Foods Ordinance) establishes minimum stocking criteria for a wide array of healthy foods as a requirement of food store licensing. To our knowledge, it is the first and only policy of its kind in the U.S. This Staple Foods Ordinance requires stores to stock specific types of foods in minimum quantities and varieties, including fruits and vegetables, low-fat dairy, and whole grains. A full list of all requirements can be found online through the City of Minneapolis: http://www.minneapolismn.gov/health/living/eating/staple-foods.
St. Paul, Minnesota Customers
No policy exists in St. Paul, Minnesota. This is the control condition.
- Healthy Food Supply (store-level) [ Time Frame: 24 months post-policy implementation (i.e., 12-months post-policy enforcement) ]To assess changes in healthy and unhealthy food availability, we will use a tool developed at the Yale Rudd Center for Food Policy and Obesity to evaluate the impact of 2009 Special Supplemental Nutrition Program for Women, Infants, and Children policy revisions in small stores, with minor adaptations to suit the needs of our study (See Andreyeva et al, J Acad Nutr Diet. 2012;112(6):850-858). As detailed in Andreyeva et al, we will create and use an an adapted Healthy Food Supply (HFS) score that summarizes availability, price, quality, and variety in the stores in our sample.We will examine changes in healthy food supply scores over time in stores in our sample in Minneapolis (where the policy is in place, i.e., our "intervention" community) versus those in St. Paul (where no such policy exists, i.e., our "control" community).
- Calories purchased (customer-level) [ Time Frame: 24 months post-policy implementation (i.e., 12-months post-policy enforcement) ]Our staff will examine all foods and beverages purchased (via a "bag check") by participating customers existing stores in our sample and will record item names, product types and weights/sizes. We will conduct detailed nutrient analyses on these purchases to assess total calories purchased and possible changes in calories purchased over time, comparing relative changes in purchasing among participants recruited outside of stores in Minneapolis (where the policy is in place, i.e., our "intervention" community) versus those in St. Paul (where no such policy exists, i.e., our "control" community).
- Healthy home food availability/obesogenicity score (customer-level) [ Time Frame: 24 months post-policy implementation (i.e., 12-months post-policy enforcement) ]Trained staffers will visit the homes of participants who report frequently shopping in small- and non-traditional food stores to complete a home food inventory using a validated assessment tool. (See Fulkerson et al, International Journal of Behavioral Nutrition and Physical Activity 2008;5(55).) Data collected using this tool will be used to create a validated summative obesogenicity score, as detailed in Fulkerson et al 2008. Changes in this score will be examined over time.
