Background: Addictive behaviours in adolescents such as alcohol consumption and smoking
are rapidly increasing worldwide.
Objective: No previous study has examined smoking status and alcohol consumption in adolescents of
Northern Greece in relation to their food habits. Therefore, we assessed the smoking status and alcohol
consumption, as well the food habits, of this population.
Method: Adolescents (495 boys and 508 girls) aged 15±1 years old and 15±2 years old respectively,
completed questionnaires regarding smoking, alcohol and food habits.
Results: Tobacco use and alcohol consumption were reported by 9.2% and 48.1% of them, respectively.
Of those that drank alcohol, 13.9% were also smokers. Older adolescents were more likely to consume
foods high in fat and sugar, low in vitamins and minerals as well as foods, considered by them to be less
healthy and prepared in a less healthy way. Moreover, smoker adolescents were less likely to choose
foods considered to be healthy and prepared in a healthy way, whereas they were more likely to choose
foods high in fat content.
Conclusions: Both smoking and alcohol consumption may affect cardiovascular risk and the vasculature.
Poor lifestyle (and risk of vascular events) can start at an early age.
