Additional Investigation Leads to Additional Funding for GOPC Project


The STaple food ORdinance Evaluation (STORE) study recently received a new grant to perform further investigation around a new policy that was put into effect last year.


fun factOn October 31st, 2014, the city of Minneapolis approved a staple food ordinance which requires all licensed grocery stores in the area to stock a series of healthy foods and beverages. The healthy foods and beverages options are based off of the Dietary Guidelines for Americans. The ordinance was then put into action the following April which is where STORE's post-policy implementation came into play.

The study aims to collect and analyze data both pre and post-policy implementation.

Pre-Policy Implementation Data Collection

The study randomly selected stores for their pre-baseline assessments which involved evaluating the food availability, food quality and price before the ordinance was put into effect. "Customer intercept surveys" were also conducted in order to record the item names, types and weight/sizes of purchases. Rapid response funding from the GOPC allowed the study to assess 119 small food stores, 71 store owners/ managers and 81 customer intercept surveys. The study was then able to increase the amount of store assessments to 140 with 616 customer intercept surveys due to additional funding from the National Institutes of Health and Centers for Disease Control and Prevention.

Post-Policy Implementation Data Collection

Initially, the study was to assess the data and customer intercept surveys during a 6-month post-policy timeframe, however, the new grant will allow further investigation to extend to 24 months. This will enable the study to evaluate the impact of the ordinance by measuring changes in both the social and home food environments as well as the nutritional quality, specifically the calories purchased, of the consumer purchases. The specific aims of this new grant will assess policy deviations including pricing, supply, and perception of the healthy food and beverage options.
