In 4234 college students, PSQI scores differed between those holding the phone >10 cm vs <10 cm from the eyes (P=0.002). Poor sleep quality risk was 1.21–1.53 times higher among students using phones >5 h/day and 1.41–1.59 times higher among those using phone…

Association between the pattern of mobile phone use and sleep quality in Northeast China college students. Sleep Breath. 2021 Feb 2. doi: 10.1007/s11325-021-02295-2. Abstract Objectives: Currently, mobile penetration is high amongst college students. The aims of this study were to investigate the characteristics of mobile phone use and to explore the influence of mobile phone use characteristics on sleep quality amongst college students. Methods: From December 2016 to January 2017, we collected mobile phone use characteristics and sleep quality data using the Pittsburgh Sleep Quality Index (PSQI) and standardised questionnaires that were answered by 4500 medical university students in Liaoning Province (actual response rate of 94%, n = 4234 college students). This study used the SPSS 21.0 software to establish the database and perform the statistical analysis. Results: One hundred percent of the college students had mobile phones and used mobile phones for entertainment (91%), work (51%), obtaining information (61%), and other purposes (23%). Additionally, there was a statistically significant difference in the PSQI score between students who held the phone at a distance of more than 10 cm from their eyes and those who held it a distance of less than 10 cm (P = 0.002). Multiple logistic regression analysis showed that the risk of poor sleep quality was 1.21-1.53 times higher for those who spent more than 5 h a day using their phones and 1.41-1.59 times higher for those who used their phones for more than half an hour before going to bed when the lights were off. Conclusions: Daily cumulative mobile phone use and use with the lights off before sleep are associated with poorer sleep quality. pubmed.ncbi.nlm.nih.gov
