This study will examine the impact of the opening of a new grocery store in a lower-income, multi-ethnic neighborhood in San Francisco. This research team has already collected two sets of baseline data from the neighborhood prior to the opening of the grocery store. This new project will allow for a final wave of endpoint data collection following the August 2011 store opening. Specific aims include: 1) assessing the impact of the opening of a full-service grocery store on healthy food and beverage availability in an underserved community, 2) assessing the impact of the store opening on the food purchasing and eating practices of local families living in the area within one year of the opening, and 3) assessing community perceptions related to the advantages and/or disadvantages of a new grocery store in their community.
