Abstract
PurposeThe purpose of this scoping review was to summarise the general results of the Chilean Food Law implementation to help to understand how this policy has changed consumer's behaviour.Design/methodology/approachPreferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) extension for scoping reviews (PRISMA-ScR) guidelines were followed. Five databases were searched for studies published from January 2015 to February 2020 evaluating the Chilean population's perception, behaviour and purchasing habits of processed foods.FindingsThe results showed that consumers support the implementation of a front-of-package warning label (FOPWL) and thought it a good strategy to help make healthier food choices for themselves. However, even with a positive perception about these products, the intention-to-change the purchase of unhealthy food occurred only for sugar-sweetened beverages. Meanwhile, children did not stop eating foods that had a FOPWL, although the mothers' perception was that the presence of FOPWLs could be important to differentiate unhealthy from healthy products. The availability of products with FOPWLs at schools decreased, indicating that the law was being complied with and that the child-directed marketing strategy showed a reduction after the first phase of implementation.Practical implicationsThis evidence will guide other countries about in understanding and improving this policy.Originality/valueThis is the first study to gather research available in international databases that evaluated the results of the Chilean Law on the advertising of children's food and the perception, purchase intention, reformulation of products and consumption behaviour of the Chilean population.
Highlights
Obesity is a global public health concern, and its prevalence is increasing in low- and middleincome countries as well as in high-income countries
Two studies (Olivares-Cortes et al, 2017; Olivares et al, 2018), including 812 children from 3 private schools and 3 public schools located in Santiago, Chillan and Temuco cities investigated critical factors associated with the efficacy of the front-of-package warning label (FOPWL) strategy
Our results showed that in the first phase of Chilean Food Law (CFL) implementation, most of the adult and child consumers understood the purpose of FOPWL
Summary
Obesity is a global public health concern, and its prevalence is increasing in low- and middleincome countries as well as in high-income countries. The main risk factors associated with obesity include socioeconomic, sociodemographic, behaviour and genetic aspects, which vary across nations and interact in a complex and multidimensional manner. To develop with effective prevention strategies for obesity, all nations must take this complexity into account (Endalifer and Diress, 2020). Foods rich in substances such as saturated fats, sodium and sugars are often classified as unhealthy since their excessive intake has shown an association with increasing levels of noncommunicable diseases and weight gain over time (Pagliai et al, 2021). Nutritional labelling normally shown in the back part of the food package is wellestablished worldwide. The adoption of front-of-package nutritional labelling (FOPNL), outlining the content of critical nutrients, has been recently encouraged as a public policy to help prevent and control obesity and related diseases
