简要总结
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.
详细描述
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.

盲法说明
This experiment will invite university students under the pretext of conducting other surveys. The content of this nudge intervention experiment will appear at the end of the Questionnaire Star platform, framed as a token of appreciation for participants' time and effort, offering a gift choice between cola and mineral water. This approach aims to prevent participants from guessing the true purpose of the experiment, which could potentially bias the experimental results.

研究组 & 干预措施
choice architecture (hedonic label Information)
Students are exposed to hedonic information about sugar-free beverages on the Wenjuanxing platform to "nudge" students towards healthier choices
干预措施: choice architecture (Behavioral)
Control
In this group, no nudge interventions were implemented, only data were collected.
choice architecture (default option)
Setting sugar-free options as the default to "nudge" students towards healthier choices.
干预措施: choice architecture (Behavioral)
choice architecture (Sugar Content Information)
Students are exposed to information about the sugar content of sugar-sweetened beverages on the Questionnaire Star platform to "nudge" students towards healthier choices
干预措施: choice architecture (Behavioral)
choice architecture (health warning Information)
The platform presented information outlining the potential health risks associated with excessive consumption of sugar-sweetened beverages.
干预措施: choice architecture (Behavioral)
结局指标
主要结局
Percentage of students who chose cola
时间窗: 1 day
Investigators will collect online records of beverage choices submitted by students on the Questionnaire Star platform. If the participant chooses a bottle of mineral water, the participant will receive a value of one. Otherwise, the participant will receive a value of zero. Investigators will use this binary measure to estimate the proportion of students who choose mineral water.
The proportion (or likelihood) of selecting sugar-free beverages
时间窗: 1 day
The probability of choosing a sugar-free beverage (binary outcome: sugar-sweetened = 0, sugar-free = 1) across five menu-selection tasks.
The proportion (or likelihood) of selecting sugar-free beverages
时间窗: day 1
The probability of choosing a sugar-free beverage (binary outcome: sugar-sweetened = 0, sugar-free = 1) across five menu-selection tasks.
