Energy drink intake and metabolic syndrome: A prospective investigation in young adults.

BACKGROUND AND AIMS

There are concerns that energy drinks (EDs) are contributing to upward trends in overweight, obesity, and cardiometabolic conditions in young people. We investigated cross-sectional and prospective associations between frequency of ED-intake in young-adults and (i) body mass index (BMI) and (ii) Metabolic Syndrome (MetS) and its components.

METHODS AND RESULTS

Participants from the Raine Study at 20-years (n = 1236) and 22 years (n = 1117) self-reported ED-intake, dietary intake, and physical activity, and had blood and anthropometric measures taken. Regression modelling examined associations between ED-intake and BMI, MetS and its components. There was a positive, but not significant, cross-sectional association with BMI and likelihood of MetS with frequent ED use at 20-years (BMI: β = 0.19; MetS: OR = 1.11) and 22-years (BMI: β = 0.51; MetS: OR = 1.28). There were no associations in the prospective analysis. After adjustment, significant associations existed between occasional ED-intake and lower HDL-cholesterol (β = -0.07) and higher fasting triglycerides (β = 0.16) at 20-years, and lower fasting triglycerides at 22-years (β = -0.10), but no significant associations in the prospective analyses.

CONCLUSION

No significant associations existed between frequency of ED-intake, and BMI, MetS or its individual components over two years (ages 20-22 years). Future studies should include volume of EDs consumed and longer follow-up.
