Student experiences with traffic-light labels at college cafeterias: a mixed methods study

Area of Science:

• Nutrition Science
• Public Health
• Behavioral Science

Background:

• College cafeterias offer opportunities to influence student dietary choices.
• Traffic-light labels (TLLs) are a visual tool to simplify nutritional information.
• Understanding student perceptions of TLLs is crucial for effective implementation.

Purpose of the Study:

• To assess college student perceptions of traffic-light labels (TLLs) in cafeterias.
• To evaluate the impact of TLLs on food choices and potential links to disordered eating behaviors.

Main Methods:

• A cross-sectional, mixed-methods study was conducted at a northeastern US college.
• 1,294 students completed surveys, and 57 participated in focus groups.
• A seven-week intervention involved TLLs (green, yellow, red) in two college cafeterias.

Main Results:

• Post-intervention, 60% of students found TLLs helpful, and 57% used them weekly.
• 16% believed TLLs increased eating disorder risk, and 47% felt they could exacerbate existing conditions.
• While some found red labels 'jarring,' most agreed more nutrition information is beneficial.

Conclusions:

• Students generally support TLLs for accessing nutrition information.
• Future college interventions must address student concerns regarding eating disorders.
• Acceptable labels should provide education, avoid negative messaging, and refrain from judgment.
