Abstract
Background: The usage of smart-devices has increased considerably both globally and specifically in Middle Eastern countries. Recently, it has been shown that 65% of United Arab Emirates (UAE) residents lack proper sleep. Several health aspects of the relationship between over usage of smart-devices and poor sleep quality have not been thoroughly investigated. This study aims to determine the correlation between smart-device overuse and sleep quality among UAE residents.
Methods: This is a cross-sectional, self-administered questionnaire-based study. Our sample comprised 494 participants, from the three major cities in the UAE. Statistical and regression analyses were conducted using SPSS.
Results: Overall, 47.5% of the population were considered heavy users of smart-devices, of which 81% were poor sleepers. Furthermore, the physical proximity of the smart-device at night affected sleep quality; as the distance decreased, the sleep quality worsened, reaching a value of 86.8%. It was also found that 74.5% of the participants used their smart-device at bedtime.
Conclusion: Poor sleep is strongly correlated with smart-device overuse. Specifically, poor sleepers were five times more likely to be overusers. The intensity and duration of smart-device usage during the whole day impacted sleep quality more drastically than just before bedtime usage. With the increasing dependence and inappropriate use of smart-devices, future studies are needed to further understand the short and long term impact of this trend on the health and wellbeing of younger individuals as well as the whole community.
