Objective: The aim of this study was to investigate the relationship between the level of smart phone addiction and the pain in cervical region-upper extremity among university students. Materials and Methods: One hundred and eighty- seven students attending the School of Health Sciences and the School of Physical Education and Sports at a public university participated in the study voluntarily. The demographic variables of the students and the amount of time they spent on a smartphone per day were recorded. Smartphone addiction level and cervical region-upper extremity pain were evaluated using Smartphone Addiction scale-short version and Visual Analog Scale, respectively. Findings: The mean age of the participants was 20,06±1,95 years, the mean age at starting using smartphone was 15,11±2,35 years and the average amount of time spent on smartphone per day was 4,36±1,79 hours. It was found that 84% of the participants did not switch off their smartphone during classes. There was a statistically significant correlation between smartphone addiction level and cervical-upper extremity pain (p<0.01). A statistically significant correlation was identified between the duration of smartphone use per day and smartphone addiction level (p<0,01), and cervical-upper extremity pain (p<0,05). CONCLUSİON: It was thought that the training programs for university students on the negative effects of smartphone addiction on the body may provide significant gains in terms of health protection and promotion.
