摘要:	Background: Using electronic devices before bedtime has an impact on sleep quality and has been concerned as a major public health issue. It's also a growing health issue in developing countries as Vietnam. Recent studies have investigated excessive electronic devices used on sleep in children and adolescents population worldwide. However, a little research deal with young adults and very little is known that using electronic devices within two hours before bedtime may relate to sleep problems. Objectives: The purpose of this study was to investigate the association between electronic devices usage before bedtime and sleep quality in a sample of Vietnamese young adults. The association of lifestyle factors and depression symptoms on sleep quality were also explored. Method: A cross-sectional study design was used in this study. The convenient sample technique was set out to recruit 369 students from three departments of Nursing, Economic Law, and Electronic at the Duy Tan University. Participants completed four sections of the self-report survey including general information, lifestyle, and electronic devices usage behaviors, the Pittsburgh Sleep Quality Index and the Center for Epidemiologic Studies Depression Scale. Data were analyzed by using descriptive statistics, One-way ANOVA test, Pearson correlation coefficient, and multiple linear regressions analysis. Results: Around half (48.8%) of the students had poor sleep quality. Approximately every student (98.1%) reported using at least one type of electronic devices every day within two hours before bedtime. The smartphone is the most used device (92.3%) and 79.4% of students keep their device within arm's reach while sleeping. Electronic device usage within two hours prior to bedtime is a risk factor for poor sleep quality (F = 4.696, p = .031), so as no exercise (F = 7.611, p = .006), alcohol consumption (F = 5.055, p = .025) and coffee intake after 4 pm (F = 5.655, p = .018). Multiple linear regression showed that duration of electronic device use within 2 hours before bedtime and depression were significant predictors of university students' sleep quality. Using electronic devices more than 2 hours is a factor for the worst PSQI score, which was highly significant with sleep quality (B = 1.974, p < .001). Conclusion: Electronic device use within two hours before bedtime is associated with poor quality of sleep in the university students. The results of the present study suggest that raising awareness about the importance of avoiding electronic devices use near bedtime is necessary to improve students' sleep quality.
