Abstract

jats:titleAbstract</jats:title>jats:sec jats:titleBackground</jats:title> jats:pNutrition facts tables (NFTs) on pre-packaged foods are widely used but poorly understood by consumers. Several countries have implemented front-of-package labels (FOPLs) that provide simpler, easier to use nutrition information. In October 2020, Mexico revised its FOPL regulations to replace industry-based Guideline Daily Amount (GDA) FOPLs with ‘Warning’ FOPLs, which display stop signs on foods high in nutrients of concern, such as sugar and sodium. This study examined self-reported awareness, use, and understanding of NFTs and FOPLs among young people in six countries with different FOPLs, with an additional focus on changes before and after implementation of Mexico’s FOPL warning policy.</jats:p> </jats:sec>jats:sec jats:titleMethods</jats:title> jats:pA ‘natural experiment’ was conducted using ‘pre-post’ national surveys in Mexico and five separate comparison countries: countries with no FOPL policy (Canada and the US), countries with voluntary FOPL policies (Traffic Lights in the UK and Health Star Ratings in Australia), and one country (Chile) with mandatory FOPL ‘warnings' (like Mexico). Population-based surveys were conducted with 10 to 17-year-olds in 2019 (jats:italicn</jats:italic> = 10,823) and in 2020 (jats:italicn</jats:italic> = 11,713). Logistic regressions examined within- and between-countries changes in self-reported awareness, use, and understanding of NFTs and FOPLs.</jats:p> </jats:sec>jats:sec jats:titleResults</jats:title> jats:pAcross countries, half to three quarters of respondents reported seeing NFTs ‘often’ or ‘all the time’, approximately one quarter reported using NFTs when deciding what to eat or buy, and one third reported NFTs were ‘easy to understand’, with few changes between 2019 and 2020. In 2020, awareness, use and self-reported understanding of the Warning FOPLs in Mexico were higher than for NFTs in all countries, and compared with GDA FOPLs in Mexico (jats:italicp</jats:italic> < .001). Mandated Warning FOPLs in Mexico and Chile had substantially higher levels of awareness, use, and understanding than the voluntary Traffic Lights in the UK and Health Star Ratings in Australia (jats:italicp</jats:italic> < .001 for all).</jats:p> </jats:sec>jats:sec jats:titleConclusions</jats:title> jats:pMandated easy-to-understand FOPLs are associated with substantially greater levels of self-reported awareness, use and understanding at the population-level compared to NFT and GDA-based labeling systems.</jats:p> </jats:sec>
