Energy Drinks in Youth: Cardiovascular Risk and a Call to Action

Area of Science:

• Cardiovascular health
• Adolescent medicine
• Public health

Background:

• Energy drinks are stimulant formulations, distinct from sports drinks, increasingly used by adolescents in athletics and social settings.
• These products contain high levels of caffeine, taurine, guarana, and other bioactive ingredients, with potential synergistic effects.
• Existing research indicates acute cardiovascular effects, including changes in blood pressure and cardiac rhythm, even at typical doses.

Purpose of the Study:

• To review the cardiovascular risks associated with energy drink consumption in adolescents.
• To understand the mechanisms by which energy drinks may trigger adverse cardiovascular events.
• To provide recommendations for clinicians, schools, and regulators regarding energy drink use.

Main Methods:

• Systematic review of randomized pediatric trials, poison-center data, and sudden cardiac arrest case series.
• Application of a trigger-substrate-context model to explain event causality.
• Analysis of ingredient interactions and dose-dependent effects.

Main Results:

• Consistent cardiovascular signals identified, including acute changes in blood pressure, autonomic regulation, and cardiac rhythm.
• Rare but severe adverse events, such as sudden cardiac arrest, have been linked to energy drink consumption.
• The trigger-substrate-context model highlights risks during exercise, dehydration, illness, or co-ingestion of other stimulants.

Conclusions:

• Clinicians must inquire about energy drink consumption, assess total stimulant exposure, and counsel minors to avoid these products.
• Recommendations include ending youth-targeted promotion, ensuring transparent labeling, and enhancing adverse event surveillance.
• Multisectoral action involving schools, athletic organizations, manufacturers, and regulators is crucial to mitigate risks.
