Study Importance

Improving access to healthy food has been identified by the Institute of Medicine, CDC and other national and scientific authorities as a strategy for local governments to help prevent obesity.

.
In the Fall of 2014, the City of Minneapolis revised an ordinance requiring all stores with grocery licenses to carry a wide array of healthy foods and beverages in order to better align with the Dietary Guidelines for Americans and stocking requirements for WIC (Women, Infants and Children) program vendors.

To date, Minneapolis is the only city in the U.S. to have a policy of this kind in place. This type of policy action may have an important impact on food access, particularly in under-served neighborhoods and small food stores that do not currently stock these types of items. This policy is expected to have the greatest impact on small-scale food retailers, such as corner stores and convenience stores, as well as non-traditional food retailers, such as gas-marts, dollar stores and pharmacies.

.

Study Purpose

The purpose of this STaple foods ORdinance Evaluation (STORE) study, therefore, is to evaluate the impact of this local policy change (i.e., the Minneapolis Staple Foods Ordinance) that establishes minimum stocking criteria for a wide array of healthy foods as a requirement of food store licensing.

.
In this study, the impact of the Minneapolis Staple Foods Ordinance will be evaluated by assessing objectively measured changes in:

  • Food environments among small- to mid-sized, urban food stores, including availability, promotion, advertising, quality, price, and placement of both healthy and unhealthy foods and beverages
  • Nutritional quality of consumer purchases at small- to mid-sized food stores, including assessment of energy density and calories via customer intercept surveys and direct observation of purchases
  • Home food environments, including availability of healthy and unhealthy foods/beverages and an overall home food obesogenicity score, among households that frequently shop at small- to mid-sized food stores.

These changes are being assessed pre-policy implementation, as well as 4-, 12- and 24-months post-policy implementation, in two Minnesota cities: Minneapolis and St. Paul (the control community).

Collaboration with the Minneapolis Health Department

This research would not be possible without the collaborative efforts in place with the Minneapolis Health Department.  To learn more about the involvement with the Minneapolis Health Department in regard to this policy, please visit: http://www.minneapolismn.gov/health/living/eating/staple-foods

 

In particular, Ms. Kristen Klingler and Ms. Nora Gordon, who work with the Healthy Living Initiative at the Minneapolis Health Department, have been critical partners in these efforts.

Funding Sources

This policy impact evaluation is funded by the National Institutes of Health (Grants 1R01DK104348-01A1, U54-HD070725 and 5R25CA057711) and the Centers for Disease Control and Prevention (3U48DP005022-01S1) through the NOPREN (Nutrition and Obesity Policy Research and Evaluation Network). For more information on NOPREN, please visit: http://nopren.org

 

Early support from the Center for Urban and Regional Affairs (CURA) Faculty Interactive Research Program at the University of Minnesota allowed us to set the stage for this large-scale funding (much of which was not available until after the revised ordinance was passed) and build infrastructure so that we were poised to conduct this large-scale policy evaluation at the appropriate point in time.
