Preventing Non-communicable Diseases in Guatemala Through Sugary Drink Reduction

Phase 3

Completed

• Conditions: Food Preferences
• Interventions: Behavioral: Exposure to beverage calorie information; Behavioral: Exposure to beverage health information

• Registration Number: NCT04022694
• Lead Sponsor: University of Pennsylvania

Brief Summary

Sugar-sweetened beverages are a significant contributor to adult and childhood obesity in Guatemala. Policies to place health warning labels on sugar-sweetened beverages are being pursued, but there is little empirical data on how such labels influence people. The primary aim of this study is to test the association between sugar-sweetened beverage (SSB) warning posters compared to control posters and change in SSBs purchased compared to baseline by adolescents shopping at school cafeterias in Guatemala City, Guatemala. The hypothesis is that posters with information warning people of the health harms associated with overconsuming SSBs and promoting low sugar beverages will be associated with greater reductions in SSB purchases compared to a control poster.

Arm && Interventions

Group	Intervention	Description
Calorie/Control Poster	Exposure to beverage calorie information	This poster will display images of both SSBs and low or no sugar beverages with calories listed below the beverages. It will simply state that those beverages are sold in the school store.
SSB Warning and Non-SSB Promotion Poster	Exposure to beverage calorie information	This poster will display images of both SSBs and low or no sugar beverages with calories listed below the beverages. In addition, the message will state that SSBs are high in sugar and should be avoided, while low or no sugar beverages are healthier options and should be chosen.
SSB Warning and Non-SSB Promotion Poster	Exposure to beverage health information	This poster will display images of both SSBs and low or no sugar beverages with calories listed below the beverages. In addition, the message will state that SSBs are high in sugar and should be avoided, while low or no sugar beverages are healthier options and should be chosen.

Primary Outcome Measures

Name	Time	Method
Volume of SSBs Per Transaction	Through study period (either 4 weeks baseline, or 4 weeks intervention)	Total milliliters of SSBs per transaction from sales data
Beverage Calories Per Transaction	Through study period (either 4 weeks baseline or 4 weeks intervention)	Total number of calories for all beverages (SSBs and non-SSBs) per transaction from sales data

Secondary Outcome Measures

Name	Time	Method
Total Calories Per Transaction	Through time frame (either 4 weeks baseline, or 4 weeks intervention)	Total number of calories for all food and beverages (SSBs and non-SSBs) per transaction from purchase assessments (e.g., calories from Coke + bag of chips)
