Effectiveness of Educational Interventions on Caffeine Habits Among Adolescents

Abstract

The caffeine consumption is very common among adolescents, often driven by academic stress and lifestyle habits. Excessive intake can lead to sleep disturbances, cardiovascular effects, dependency and poor dietary practices. Despite its widespread use, knowledge regarding safe limits and associated health risks remains limited among young populations. A single-group study was conducted in April 2024 among undergraduate students (aged 18–19). A total of 60 participants were included in the study.  A validated, structured questionnaire assessed baseline knowledge of caffeine and its health effects. Participants received an informative educational booklet followed by a post-test to evaluate changes in awareness. Before the intervention, 30% of participants demonstrated good knowledge, while 13% had poor knowledge. Post-intervention, all students (100%) achieved good knowledge levels. The pre-test score (10.58±2.54) was, significantly increased post-intervention (17.33±1.96) (t = 18.740, p <0.0001). No significant associations were found between knowledge score and demographic variables. The study revealed a lack of baseline knowledge regarding caffeine's adverse effects among adolescents. A structured educational booklet significantly improved awareness, underscoring the need for early educational interventions to promote healthy caffeine habits and informed lifestyle choices.
