Food Selection, Obesity
Conditions
Brief 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.
Detailed description
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 study will be conducted in a classroom setting, where participants will be randomly assigned to one of four groups: a no-nudge control group, a health warning group, a hedonic labeling group, and a combined health warning plus hedonic labeling group.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| 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. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Participants' Perceived Intrusiveness of Nudges | day 1 | A 5-point Likert scale (1 = strongly disagree, 5 = strongly agree) was employed. Higher scores indicate greater perceived intrusiveness. |
| Participants' Support for Nudges | day 1 | A 5-point Likert scale (1 = strongly disagree, 5 = strongly agree) was employed. Higher scores indicate greater support for the nudging strategy |
| Participants' Perceived effectiveness of Nudges | day 1 | A 5-point Likert scale (1 = strongly disagree, 5 = strongly agree) was employed. Higher scores indicate greater perceived effectiveness. |
