Exploring the Association Between Internet Use and Dietary Habits of Adolescents and University Students in Greece: A...

Background/Objectives: Adolescents and university students appear to be at increased risk for internet addiction (IA), while disordered eating behavior (DEB) is common in these age groups. At the same time, adherence to the Mediterranean diet (MD) has declined in many countries. This study aimed to explore the potential association between IA, DEB and MD compliance among high school and university students. Methods: A total of 212 students aged 15-24 years participated in this cross-sectional study conducted in Greece. Data were collected via an online questionnaire including the Internet Addiction Test (IAT), KIDMED, and EAT-26 scales. Descriptive statistics, chi-square tests, and univariate and multivariate logistic regression analyses were performed. Results: Most participants demonstrated normal internet use (69.8%), while 23.1% showed mild IA and 7.1% moderate IA. Regarding dietary habits, 9.4% had low MD adherence, 52.8% moderate and 37.7% high adherence. A total of 15.6% scored above the EAT-26 cut-off, indicating risk for disordered eating behavior. IA was only significantly associated with urbanization (p = 0.014). MD adherence was not associated with gender, urbanization, financial or education status. Multivariate logistic regression showed that female gender (OR = 9.28, 95% CI: 2.10-40.91, p = 0.003) and moderate IA (OR = 6.70, 95% CI: 1.71-26.35, p = 0.006) were significant predictors of disordered eating, while educational status and MD adherence were not significant predictors. Conclusions: Moderate IA and female gender were strongly associated with an increased risk for disordered eating. Further qualitative and clinical studies are needed to better understand the interaction between IA, eating behaviors, and dietary patterns in young people.
