Assessment of relationship between the use of cell phone and social networks and sleep quality in students of medical sciences: A cross-sectional study.

Introduction: Sleep quality is an essential aspect in human health and function. Considering high prevalence of using smartphones and social networks among students and their impact on sleep quality, this study was conducted to determine the relationship between the overuse of cell phone and addiction to social networks and students' sleep quality.

Materials and methods: This cross-sectional study was conducted in Kermanshah University of Medical Sciences, Kermanshah, Iran in 2018. Using cluster sampling, 321 students from different disciplines were selected. Data gathering tools consisted of the questionnaire of Pittsburgh Sleep Quality Index (PSQI). Cell phone use and addiction to social networks were assessed using Cell Phone Overuse Scale and a researcher-made questionnaire, respectively. Data were analyzed using SPSS software (version 19) and Pearson's correlation test.

Results: The mean total score of sleep quality in students was 6.58 ± 1.05. There was a positive and significant correlation between sleep quality and social networks addiction score (p < 0.05, r = 0.5) and cell phone overuse (p < 0.05, r = 0.44); this is an inverse correlation, because higher scores of the total PSQI denote a lower sleep quality and, in Cell Phone Overuse Scale, higher scores shows overuse.

Conclusions: According to the findings of this study, there was a significant statistical relationship between the overuse of cell phone and social networks and students' sleep quality. In other words, students who have had overuse of cell phones had poorer sleep quality. Therefore, providing effective educational programs to improve the sleep quality in this group is essential.
