Objective:
To assess food supply adequacy within 3 food store types in the Lower Mississippi Delta.
Design:
Regional food store survey to determine availability and quality of 102 food items in 62 supermarkets, 77 small/medium stores, and 86 convenience stores.
Setting:
Lower Mississippi Delta region of the United States.
Participants:
225 food stores in 18 counties.
Main Outcome Measures:
Percentage of Thrifty Food Plan (TFP) food items available and quality ratings of 6 food sections across store types.
Results:
On average, supermarkets carried 96% of the items that compose the TFP. Mean percentage of TFP carried in small/medium stores was 50%. Convenience stores carried 28% of the TFP items. Supermarkets had higher overall quality ratings and quality ratings for fresh and frozen foods compared to small/medium and convenience stores (P<.01).
Implications For Research And Practice:
Although supermarkets carried a large percentage of items surveyed, the number of supermarkets in this region is limited. Community residents with limited transportation to reach supermarkets may experience limited food supply adequacy. Therefore, community-based nutrition interventions should include partnerships with small/medium food retailers while trying to impact residents' food choices within those stores.
