Energy drink consumption linked to male anxiety

Perth researchers examined associations between frequency and quantity of intake of the caffeine-laced drinks and mental health indicators using DASS-21 questionnaires in about 500 males and 500 females aged 20 years in the Raine birth cohort.

Some 27% of men consumed energy drinks weekly and 3% daily. Those with the highest consumption had increased risk of anxiety but not depressive symptoms.

It is unclear whether the drinks cause anxiety or if anxious people are more likely to drink them. But it is clear that 20-year-old men who regularly consume them are likely to be anxious.

Drinking 250ml or more a day is associated with increased anxiety and the association gets stronger as consumption increases, said lead author Dr Georgina Trapp of the Telethon Institute for Child Health Research.
