Summary

Ethiopia is experiencing the type of rapid food system transformation that leads to a double burden of malnutrition and increased non-communicable diseases. Front-of-pack labels on packaged foods are an emerging public health strategy with the potential to address non-communicable diseases by discouraging the purchase and consumption of products with high levels of nutrients of public health concern. The aim of this study is to evaluate and compare the effectiveness of front-of-pack labeling systems to reduce the intent to purchase unhealthy foods among adults in Ethiopia. The study will recruit approximately 1200 adults using a street-intercept methodology. Participants will be randomized to 1 of 4 arms to complete a survey in which the presence and type of front-of-pack label differs across survey arms and asked to rate participants' intent to purchase unhealthy packaged foods.

Detailed description

In 2017, cardiovascular disease was the leading age-standardized cause of death in Ethiopia. The national prevalence of hypertension in Ethiopia in 2015 is estimated to be 16% (Gebreyes et al. 2018). Urban diets are rapidly changing, but not becoming healthier (Wolle et al. 2020). Diet quality remains poor: only 2.4% of the national population meets the WHO recommendation of five servings of fruit and vegetables per day. The mean estimated salt intake of 8.3 g/day exceeds the WHO maximum recommended intake (Challa et al. 2017). Processed foods are penetrating the market at a rapid pace (Melesse et al. 2019; Stuckler et al. 2012). Increasing income has increased demand for convenience foods (Minten et al. 2018). Ethiopia is experiencing the type of rapid food system transformation that leads to a double burden of malnutrition and increased non-communicable diseases (Popkin 2017). Front-of-pack labels on packaged foods are an emerging public health strategy with the potential to address non-communicable diseases by discouraging the purchase and consumption of products with high levels of nutrients of public health concern (Croker et al. 2020). However, front-of-pack labels have not been tested in the Ethiopian context. Additionally, there are multiple types of front-of-pack labeling systems in use around the world, such as Multiple Traffic Light/Guideline Daily Amounts, the Nutri-Score system, and nutrient-specific warning labels. Therefore, the study aims to to evaluate and compare the effectiveness of front-of-pack labeling systems to reduce the intent to purchase unhealthy foods among adults in Ethiopia. The study will recruit approximately 1200 adults using a street-intercept methodology. Participants will be randomized to 1 of 4 arms to complete a survey in which the presence and type of front-of-pack label differs across survey arms and asked to rate participants' intent to purchase unhealthy packaged foods.

Interventions

Type	Name	Description
OTHER	Front-of-pack labeling	The intervention being tested is the effect of front-of-package labeling on consumers' intent to purchase foods which are high in one or more nutrients of public health concern. Participants randomized to the control group will view images of packaged foods and beverages and answer a series of questions about those products. In the intervention arms, participants will view images of the same packaged foods and beverages, but with different front-of-package labels displayed that provide nutrition information about the product. Participants in each arm will be asked the same series of questions about the products shown.
