Background: Many commercial infant and toddler foods (CITFs) contain added sugars, which contribute to tooth decay, unhealthy weight gain, and lifelong chronic disease risk. CITFs are often marketed as healthy, nurturing and convenient. Displaying front-of-pack Added Sugar Warning Labels (ASWLs) on CITFs with added sugar could help counter misleading marketing and raise awareness of potential product harms.
Aims: Test whether mandatory Added Sugar Warning Labels (ASWLs) prompt parents to select CITFs without added sugar for their infant/toddler to consume.
Methods: In a naturalistic, between-subjects experiment, 533 Australian parents were assigned to an infant or toddler food study arm, then randomly allocated to a warning label condition: no ASWL (control) or ASWL. Within each of three product categories, parents were shown four CITFs (two with added sugars, two without) – with ASWLs displayed accordingly. Analyses examined effects of ASWLs on perceived added and total sugar content, perceived healthiness, purchase intentions and purchasing choices
Findings: Compared to the control condition, ASWLs significantly decreased perceived healthiness of CITFs containing added sugar (M: 3.3 vs. 2.9), increased perceived total sugar content (M = 4.3 vs. 4.9), and increased the likelihood of parents identifying that these products contained added sugar (61% vs. 89%). ASWLs also significantly reduced parents' likelihood of choosing
Conclusions: Displaying ASWLs on CITFs with added sugar increased awareness of total sugar content and the presence of added sugars, and reduced perceptions of product healthiness, curbing parents’ preferences and purchasing intentions for CITFs with added sugar. Findings indicate that warning labels offer a promising strategy for discouraging parents from purchasing CITFs with added sugar and reorienting them towards choosing options without added sugar for their children.
