56 % of the medical students reported a daily mobile phone use of of less than 30 min, 28 % of 30 to 60 min, 11.5 % of 60 to 90 min, and 4.5 % of more than 90 min. 30.8 % of the students reported their health status as very good, 62.2 % as good and 7 % as fair. The mostly reported symptoms among mobile phone users were memory disturbances (40.6 %), sleeplessness (38.8 %), and hearing problems (23.1%). 44.4 % of the students related their symptoms to mobile phone use. The author concluded that the results showed that mobile phones play a great part in the daily life of medical students, and therefore the impact on psychology and health should be discussed to prevent harmful effects of mobile phone use.
