Introduction: Intake of caffeine containing beverages such as coffee, tea or energy drinks is on a rise among children and adolescents. Children are considered more sensitive to caffeine because of continued brain development involving myelination and pruning processes. Children may develop agitation, tachycardia, gastrointestinal disturbance, nausea and diuresis because of caffeine toxicity. This study was conducted to find out the daily consumption of caffeine in adolescents and to determine the reasons that prompt its intake.

The mean caffeine intake of group of participants was 103mg, of which coffee and tea contributed the most. The most common reasons for taking caffeine items were along with adults as part of daily routine (60%), to tackle drowsiness and be alert full (20%), to increase concentration (18%) followed by to reduce headache (15%). Conclusion: In our study we found that the most common caffeinated items consumed were tea and coffee.
