Background: Labels are a key element of the marketing strategies of infant formula companies, and often include text or images that idealize their use, undermining efforts to promote breastfeeding.
Research aims: To evaluate the prevalence of marketing cues that idealize infant formula on labels of products commercialized in Uruguay and to assess changes after a periodic monitoring of compliance with the International Code of Marketing of Breast-Milk Substitutes (IC).
Method: This study is a descriptive, observational, and longitudinal assessment of the information included on infant formula labels. The first data collection was in 2019, as part of a periodic assessment to monitor the marketing of human-milk substitutes. In 2021, the same products were purchased to evaluate changes in their labels. Thirty-eight products were identified in 2019, of which 33 were still available in 2021. All information available on the labels was analyzed through content analysis.
Results: Most products included at least one textual or visual marketing cue idealizing infant formula in both 2019 (n = 30, 91%) and 2021 (n = 29, 88%). This represents a violation of both the IC and national regulations. References to nutritional composition were the most frequent marketing cue, followed by references to child growth and development. No relevant changes were observed after the periodic assessment conducted by the Uruguayan government.
Conclusions: Monitoring compliance with the IC per se cannot be expected to trigger changes in the marketing strategies of infant formula companies. More explicit regulations and strong enforcement mechanisms are needed to end the inappropriate marketing practices on infant formula labels.
