Internet addiction in Greek medical students: an online survey.

OBJECTIVE: The authors investigated the prevalence of Internet addiction (IA) in undergraduate medical students to identify possible associations with sociodemographics and Internet habits. METHODS: All students at the Aristotle University of Thessaloniki School of Medicine, Greece, were invited to complete the online Internet Addiction Test (IAT) along with sociodemographics and preferences on Internet activities. RESULTS: The authors received 585 responses after three reminders (23.5 % response rate). Mild IA was found in 24.5 %, moderate in 5.4 %, and severe in 0.2 %. In multivariable analysis, the odds to develop IA were increased with visits in Internet cafes (Odds Ratio [OR] 3.49, 95 % Confidence Interval [CI]: 1.45, 8.46), the use of Facebook (OR 2.43, 95 % CI: 1.35, 4.38), Twitter (OR 2.45, 95 % CI: 1.37, 4.39), and online games (OR 1.95, 95 % CI: 1.29, 2.94). Using e-mails seemed to be protective against IA (OR 0.59, 95 % CI: 0.37, 0.94). CONCLUSION: This is the first IA prevalence study in a European medical school. Early-detection systems and other ways to help students with pathological behaviors should be developed.
