Evaluation of a national supermarket intervention supporting vulnerable families in healthy meal practices: a natural experiment.

ABSTRACT:

Background

Lower socioeconomic status (SES) is linked to diets that do not meet dietary guidelines. The "Dinner is served at 1-2-3 euros" (DS123) supermarket intervention aims to support vulnerable families in cooking more home-made meals, combining food literacy strategies and price incentives. This study evaluated its impact on food purchases.

Methods

Food purchase data (total number of product purchases, n = 260,214) from participating families with lower SES (n = 134) were analyzed over a period of four and a half years, using a longitudinal within-group pre-post design. Binomial generalized linear mixed models assessed changes in the proportion of total food budgets spent on vegetables, prepackaged meals, and sweet and salty snacks.
