The consumption of energy drinks has become increasingly prevalent among high school students, raising concerns about the potential negative effects on their health. Energy drinks contain ingredients such as caffeine, taurine, and sugar, which act as stimulants and can have harmful impacts on the cardiovascular, neurological, and mental systems. The objective of this study was to analyze the prevalence of energy drink consumption among high school students in Varaždin County, and to identify the main reasons for this consumption. Based on these insights, the study aims to provide guidelines for educating young people about the dangers associated with energy drinks. The research was conducted through a survey involving 1987 students from ten high schools in Varaždin County. The questionnaire consisted of 12 questions, two of which were demographic, and the remaining ten focused on the students’ habits and attitudes toward energy drinks. Participation in the survey was voluntary and anonymous. Data were analyzed using descriptive statistics, and the Chi-square test was employed to assess the statistical significance of relationships between variables, such as gender and age. The data analysis was performed using Microsoft Excel, with the results presented in tables and charts. The findings revealed that 86.51% of the high school respondents had consumed energy drinks. Male students were statistically more likely to consume these beverages compared to female students. Additionally, energy drink consumption increased with age, with older students showing a higher propensity for consuming them. The main reasons cited by students for energy drink consumption included fatigue, particularly during academic activities, and the need for refreshment after physical activities such as sports. Interestingly, girls were more likely to cite fatigue as a reason for consumption, while boys more frequently consumed energy drinks for refreshment after physical exertion. The results of this study highlight a concerning trend of high levels of energy drink consumption among high school students in Varaždin County. These findings suggest that young people may not be fully aware of the potential long-term health risks, even though many are aware of the ingredients in the drinks they consume. Education focused on the harmful effects of energy drinks, including cardiovascular issues, sleep disorders, and caffeine dependence, is essential to reducing their use. Additionally, there is a need to promote healthier alternatives, such as water or caffeine-free beverages, particularly in the context of physical activities. Schools and parents should collaborate on educating young people, while policymakers should consider regulating the availability of energy drinks to minors, with the aim of mitigating their long-term negative impact on youth health.
