OBJECTIVE:
This study tested the efficacy of a multicomponent supermarket point-of-purchase intervention featuring in-person nutrition education on the nutrient composition of food purchases.

DESIGN:
The design was a randomized trial comparing the intervention with usual care (no treatment). 

SETTING AND PARTICIPANTS:
A supermarket in a socioeconomically diverse region of Phoenix, AZ. One hundred fifty-three adult shoppers were recruited onsite.

INTERVENTION:
The intervention consisted of brief shopping education by a nutrition educator and an explanation and promotion of a supermarket point-of-purchase healthful shopping program that included posted shelf signs identifying healthful foods, sample shopping lists, tips, and signage.

MAIN OUTCOME MEASURES:
Outcomes included purchases of total, saturated, and trans fat (grams/1,000 kcal), and fruits, vegetables, and dark-green/yellow vegetables (servings/1,000 kcal) derived through nutritional analysis of participant shopping baskets. ANALYSIS: Analysis of covariance compared the intervention and control groups on food purchasing patterns while adjusting for household income.

RESULTS:
The intervention resulted in greater purchasing of fruit and dark-green/yellow vegetables. No other group differences were observed.

CONCLUSIONS AND IMPLICATIONS:
Long-term evaluations of supermarket interventions should be conducted to improve the evidence base and to determine the potential for influence on food choices associated with decreased chronic disease incidence.
