A randomised experimental study comparing perceptions of two energy drink health warning labels

Area of Science:

• Public Health
• Health Psychology
• Consumer Behavior

Background:

• Energy drink consumption is a significant public health issue, especially among adolescents and young adults.
• Understanding consumer responses to warning labels is crucial for developing effective public health interventions.
• Previous research has focused on general health warnings, but specific warnings for energy drinks require further investigation.

Purpose of the Study:

• To compare consumer reactions to energy drink-specific cardiac effect warning labels versus general sugary drink obesity warning labels.
• To assess the impact of different warning labels on intentions to reduce energy drink consumption.
• To evaluate perceived health threat, label effectiveness, and policy support for energy drink warning labels.

Main Methods:

• An online experimental study was conducted with 435 Australian energy drink consumers aged 18-39 years.
• Participants were randomly assigned to view either a cardiac effects warning label or an obesity warning label.
• Key outcome measures included intention to reduce consumption, perceived health threat, perceived label effectiveness, and policy support.

Main Results:

• Intention to reduce consumption scores were similar across both label conditions overall.
• The cardiac effects label showed higher effectiveness for subgroups including females, older adults (25-39 years), and those with higher education levels.
• The cardiac label was perceived as more believable and relevant, and led to greater policy support compared to the obesity label.

Conclusions:

• Energy drink consumers perceive health effect warning labels as impactful and support their implementation.
• Warning labels highlighting energy drink-specific health effects, such as cardiac risks, may offer additional public health benefits.
• Policymakers can be confident in the public health benefits of implementing warning labels on energy drinks.
