A Mediational Evaluation of Smartphone Addiction Effect on Insomnia and Sleepiness in Adolescents and Young Adults

Objective: Good sleep quality is an important factor for a healthy life. The aim of this study was to investigate the factors affecting insomnia and daytime sleepiness in adolescents and young adults. Materials and Methods: This cross-sectional study was conducted on 394 adolescents and young adults aged between 15 to 30 years. Our questionnaire consisted of a sociodemographic section, questions about factors affecting sleep quality, Smartphone addiction scale-short form, Epworth Sleepiness Scale, and Insomnia Severity Index Scale. Results: The mean age of the 394 participants was 20 +/- 3.65 years. Risk factors for insomnia in adolescents and young adults were found to be smoking, caffeine consumption between the hours of 18:00-24:00, pre-sleep eating habits, and possible smartphone addiction. Risk factors for daytime sleepiness included being female, daytime sleeping habits, lack of regular physical activity habits, and possible smartphone addiction. The rates of sleepiness and insomnia were higher in both those under the age of 18 and those with possible smartphone addiction. A weak positive correlation was found between smartphone addiction, daytime sleepiness, and insomnia. Smartphone addiction increased the risk of daytime sleepiness by Odds ratio (OR)=2.652 times and moderate-clinical insomnia severity by OR=2.102 times, while lack of physical activity habit increased daytime sleepiness by OR=1.801 times. Smartphone addiction was found to be a partial mediator of sleepiness. Conclusion: Smartphone addiction is directly and indirectly associated with sleep problems in adolescents and young adults.
