Using Nudge Strategies to Promote Healthier Beverage Intake Among College Students

The primary objective of this study was to examine whether four nudging strategies influence beverage consumption behavior among Chinese university students. These interventions included sugar content information, health warning messages, hedonic labeling, and default option nudge. 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.

About this study

As the prevalence of overweight, obesity, and chronic diseases continues to escalate, excessive consumption of sugar-sweetened beverages (SSBs) has emerged as a growing public health concern globally. One approach to reducing beverage intake while conserving resources is the utilization of nudge strategies. Nudge strategies, characterized by their low cost and ease of implementation, facilitate individuals in making more accurate and beneficial choices in a predictable manner, through subtle interventions that do not prohibit any options or significantly alter incentives. This nudge experiment will be conducted in a classroom setting, where participants will be randomly assigned to one of five groups for beverage selection, completing a menu-based choice task: a no-nudge control group, a default option group, a hedonic labeling group, a sugar content information group, and a health warning nudge group.

Treatment and study plan

Choice Architecture

Behavioral

Display the sugar content of the drink on the platform.

Primary outcomes

  1. The proportion (or likelihood) of selecting sugar-free beverages

    Time frame: day 1

    The probability of choosing a sugar-free beverage (binary outcome: sugar-sweetened = 0, sugar-free = 1) across five menu-selection tasks.

Secondary outcomes

  1. Participants' Perceived Intrusiveness of Nudges

    Time frame: day 1

    A 5-point Likert scale (1 = strongly disagree, 5 = strongly agree) was employed. Higher scores indicate greater perceived intrusiveness.

  2. Participants' Support for Nudges

    Time frame: day 1

    A 5-point Likert scale (1 = strongly disagree, 5 = strongly agree) was employed. Higher scores indicate greater support for the nudging strategy

  3. Participants' Perceived effectiveness of Nudges

    Time frame: day 1

    A 5-point Likert scale (1 = strongly disagree, 5 = strongly agree) was employed. Higher scores indicate greater perceived effectiveness.
