Studies find increasing trend among children, adolescents and young adults to spend excessive amounts of time surfing in the Internet. Another serious problem is the increasing proportion of young people who are overweight and obese. There are only few papers trying to correlate these two trends.

Each participant filled in an authors' questionnaire about his/her basic social and medical information. For each participant BMI was calculated.

The study revealed also several statistically significant relationships between the level of Internet addiction and the time spent online, BMI, back pain, headache.
