Advertisements of ultra-processed products outside food outlets: Field evidence from Montevideo, Uruguay.

Abstract

Objectives: To evaluate the prevalence of advertisements of ultra-processed products outside food outlets in Montevideo (Uruguay) and to explore the patterns of these advertisements across areas with different socio-economic status.

Design: Cross-sectional field survey of advertisements of ultra-processed products outside food outlets. The percentage of outlets featuring any type of advertisement of ultra-processed products on the exterior part of the outlets was calculated, at the aggregate level and separately by type of outlet and type of product. Comparisons were made considering the socio-economic status of the tract where outlets were located.

Setting: 106 census tracts in Montevideo, differing in geographical location and socio-economic status.

Participants: Outlets selling foods and beverages, located within the selected census tracts.

Results: 30.7% of the 1,217 food outlets identified in the field survey featured some type of exterior advertisement of ultra-processed products. Sweetened beverages (specifically soda) was the most frequently advertised ultra-processed product category, followed by ice-cream. After adjusting for the type of outlet, medium SES tracts exhibited the highest prevalence of ultra-processed product advertisements outside food outlets (36.0%). Differences in the prevalence of advertisements of specific categories with SES were also found, which may reflect variations in the types and characteristics of food outlets.

Conclusions: Results from the present work suggest frequent exterior advertisements of ultra-processed products and highlight the need to develop effective policies to reduce their use as part of a comprehensive set of strategies to discourage consumption of ultra-processed products.
