Caffeine intake from carbonated beverages among primary school-age children

The aim of the study was to assess caffeine intake from cola beverages and energy drinks, as well as the consumption frequency among primary-school-age children in relation to other dietary habits.

The study included 329 children (aged 11-13 years) from five randomly selected schools in Warsaw. Caffeine intake was assessed from a food frequency questionnaire. The face-to-face interview method was selected.

89.7% of the children consumed carbonated beverages whom caffeine, of which nearly 24% consumed energy drinks. The median caffeine intake from carbonated beverages was 0.12 mg/kg body weight/day, accounting for 4.8% of the recommended maximum daily intake from all dietary sources. Frequent consumers of cola drinks were often found to eat fast foods, as well as salty snacks.

Caffeine intake in the studied group of children turned out to be at a safe level. The safe dose of caffeine does not mean that consumption of carbonated drinks should not raise any concerns. The recently established legal ban on selling unhealthy foods at school is a good idea, since the school should not be a place for improper dietary models.
