The Effects of Mobile Electronic Devices Use on the Sleep States of University Students

OBJECTIVE: In this study, the purpose was to evaluate the effect of mobile electronic devices (MEDs) use on the sleep states of university students. METHODS: The study was conducted in a cross-sectional fashion between April 21, 2019 and May 31, 2019 with the participation of the students registered in a public university at medical faculties and faculty of health sciences. Television viewing, MED and desktop computer use form, Morningness-Eveningness Questionnaire, Pittsburgh Sleep Quality Index (PSQI), Epworth Sleepiness Scale (ESS), and Sleepiness Severity Index (SSI) were used as data collection tools. The data of 752 students (56.5% girls, mean age: 20.57 [SD = 1.54] years) were analyzed. RESULTS: In this study, overall MED use times and PSQI, ESS, and SSI total scores were higher in students who had an evening-oriented chronotype. There was a negative relationship between overall and evening MED use times and the chronotype scores of the students. As a result of the regression analyses applied to the PSQI, ESS, and SSI dependent variables, a positive and significant relationship was detected with smartphone use times (P < 0.05, P = 0.05, and P < 0.001, respectively). In addition, there was a positive relationship between PSQI and ESS variables and iPod touch use times (P < 0.001 and P < 0.05, respectively). CONCLUSION: Overall MED use times were determined to be higher in students who had Type E chronotype. It was also determined that their sleep quality was poorer and their insomnia severity was higher, and there was more sleepiness in the students with chronotype E. Comprehensive interventions must be planned by professional healthcare staff for students on the topics of sleep hygiene and conscious media use.
