Condition(s) studied

Investigational drug(s) / intervention(s)

choice architecture: Showing the various harms that can come from long-term excessive consumption of sugary beverages on the platform.

choice architecture: The platform shows the hedonic information about sugar-free beverages.

choice architecture: The platform shows both hedonic information about sugar-free beverages and information on the various harms of long-term excessive sugary beverage consumption.

Study summary

The primary objective of this study was to examine whether three nudging strategies influence beverage consumption behavior among Chinese university students. These interventions included health warning messages, hedonic labeling, and a combination of health warning and hedonic labeling. A between-subjects experimental design with a single factor was employed to assess the effects of these strategies on students' choices between sugar-sweetened and sugar-free beverages, thereby evaluating their effectiveness in promoting healthier beverage selections.

Eligibility

Primary outcome measure(s)

• The proportion (or likelihood) of selecting sugar-free beverages — day 1
  The probability of choosing a sugar-free beverage (binary outcome: sugar-sweetened = 0, sugar-free = 1) across five menu-selection tasks.
