Detailed Description
Fruit drinks are widely consumed by 0-5-year-olds. Parents purchase these drinks for their children in part due to misperceptions that they are healthful, which may be driven by front-of-package (FOP) marketing. The FDA is considering changes to FOP marketing regulations but lacks data on how label elements influence consumer behavior. Our study will test the independent and combined effects of FOP claims, imagery, nutrition disclosures, and added sugar warning labels on parents' purchases and perceptions of beverages for their children.
We will conduct an online randomized controlled trial with 5,000 racially/ethnically diverse primary caregivers of children aged 0-5 years. Participants will choose a beverage for their child in an online store and rate health perceptions of different fruit drinks. Participants will be randomized to see high-added-sugar beverages (>20% DV added sugar/serving) with 1 of 7 FOP label conditions: 1) vitamin C claim and fruit imagery (control); 2) imagery only; 3) claim only; 4) no claim or imagery; 5) claim, imagery, and % juice disclosure; 6) claim, imagery, and added sugar warning; or 7) claim, imagery, and added sugar warning w/teaspoons of added sugar.
Primary outcomes will include total calories and added sugar (grams) from chosen online store beverages. Secondary outcomes will include health perceptions and knowledge of added sugar and % juice content in low- and high-added-sugar fruit drinks.
This research will inform federal regulation to correct health misperceptions of sugary drinks.
