title: Eat Right-Live Well! Supermarket Intervention Impact on Sales of Healthy Foods in a Low-Income Neighborhood.
abstract: OBJECTIVE
  To evaluate a multifaceted supermarket intervention promoting healthier alternatives to commonly purchased foods.
  
  
  METHODS
  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.
  
  
  METHODS
  Two supermarkets in geographically separate, low-income, urban neighborhoods.
  
  
  METHODS
  One control and 1 intervention supermarket.
  
  
  METHODS
  Product labeling, employee training, community outreach, and in-store promotions, including taste tests.
  
  
  METHODS
  Number of items sold; absolute and percent differences in sales.
  
  
  METHODS
  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
  Store-based interventions, particularly high-fidelity labeling, can increase promoted food sales.
