Brief Summary

Improving healthy food availability and decreasing the availability of high calorie, low nutrient products, particularly in underserved communities, has been identified as a leading strategy for local governments to prevent obesity. However, policy action in this area to date has been limited. This R01 will examine the impact of a local policy change that establishes minimum stocking criteria for a wide array of healthy foods as a requirement of food store licensing. To our knowledge, this is the only policy of its kind in the US. As such, if it is successful, it could serve as an important model policy for other local governments seeking to increase healthy food availability and prevent obesity through local policy action.

Outcome Measures

Primary Outcomes (2)

• Healthy Food Supply (store-level)

  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).

  24 months post-policy implementation (i.e., 12-months post-policy enforcement)

• Calories purchased (customer-level)

  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).

  24 months post-policy implementation (i.e., 12-months post-policy enforcement)

Other Outcomes (1)

• Healthy home food availability/obesogenicity score (customer-level)

  24 months post-policy implementation (i.e., 12-months post-policy enforcement)

Study Arms (2)

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.

Other: Policy

St. Paul, Minnesota Customers

No policy exists in St. Paul, Minnesota. This is the control condition.

Interventions

Policy OTHER

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.
