Of the students, 57.3% had poor sleep quality and 82.5% had normal daytime sleepiness. Daily smartphone use duration, owning of a smartphone duration, daytime sleepiness and academic success were significant influencing factors for smartphone addiction (p < 0.05). Daily sleep duration, daytime sleepiness and school region were found significant risk factors for sleep quality (p < 0.05). Sleep quality and smartphone addiction significantly influenced daytime sleepiness (p < 0.05).Conclusions: The study revealed that almost half of nursing students presented smartphone addiction and more than half of them had poor sleep quality. The prevalence of normal daytime sleepiness among nursing students was high.
