Abstract
Objective
To evaluate a multifaceted supermarket intervention promoting healthier alternatives
to commonly purchased foods.
Design
Sales of 385 foods promoted between July and October, 2012 in the Eat Right–Live Well! intervention supermarket were compared with sales in a control supermarket.
Setting
Two supermarkets in geographically separate, low-income, urban neighborhoods.
Participants
One control and 1 intervention supermarket.
Intervention
Product labeling, employee training, community outreach, and in-store promotions,
including taste tests.
Main Outcome Measures
Number of items sold; absolute and percent differences in sales.
Analysis
Difference-in-difference analyses compared absolute and percent changes between stores
and over time within stores. Sub-analyses examined taste-tested items and specific
food categories, and promoted items labeled with high fidelity.
Results
Comparing pre- and postintervention periods, within-store difference-in-differences
for promoted products in the intervention store (25,776 items; 23.1%) was more favorable
than the control (9,429 items; 6.6%). The decrease in taste-tested items' sales was
smaller in the intervention store (946 items; 5.5%) than the control store (14,666
items; 26.6%). Increased sales of foods labeled with high fidelity were greater in
the intervention store (25,414 items; 28.0%) than the control store (7,306 items;
6.3%).
Conclusions and Implications
Store-based interventions, particularly high-fidelity labeling, can increase promoted
food sales.
