Brief Summary

Sugar-sweetened beverages (SSBs) are a significant contributor to adult and childhood obesity. 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 proposed research will evaluate the impact of different types of sugar-sweetened beverage warning labels relative to standard calorie labels on the purchasing and consumption behaviors of parents and children.

Study Arms (3)

Calorie/Control Label Condition

ACTIVE COMPARATOR

Beverages at the concession stand and in the parent survey in this arm will display solely a calorie label.

Behavioral: Exposure to beverage calorie information

Text Warning Label Condition

EXPERIMENTAL

Sugary beverages at the concession stand and in the parent survey in this arm will display both a text warning and a calorie label.

Behavioral: Exposure to sugar-sweetened beverage warning labels; Behavioral: Exposure to beverage calorie information

Sugar Graphic Label Condition

EXPERIMENTAL

Sugary beverages at the concession stand and in the parent survey in this arm will display a sugar graphic warning label depicting the amount of sugar in the product, the same text warning, and a calorie label.

Behavioral: Exposure to sugar-sweetened beverage warning labels; Behavioral: Exposure to beverage calorie information

Interventions

Exposure to sugar-sweetened beverage warning labels BEHAVIORAL

Graphic images of the amount of sugar (randomly assigned teaspoons, packets, or cubes) and text warning labels

Sugar Graphic Label Condition; Text Warning Label Condition

Exposure to beverage calorie information BEHAVIORAL

Calories for sugar-sweetened and non-sugar-sweetened beverages

Calorie/Control Label Condition; Sugar Graphic Label Condition; Text Warning Label Condition

Model Details: This randomized, controlled lab-based study will capture beverage and snack purchases from a concession stand and measure how much participants consume while watching a television show. Participants will be randomized to 1 of 3 groups: 1) calorie labels (control); 2) text warning labels; or 3) graphic warning labels displaying amounts of sugar.
