Effect of Electronic Media Use on Sleep Quality in Adolescents: A Cross-Sectional Study

Background and Objective Adolescent sleep deprivation, increasingly driven by digital media, poses a significant threat to cardiovascular health by promoting risks like obesity and hypertension. To address these modifiable factors, this study measures daily screen time duration and sleep patterns among adolescents to identify behavioural precursors to early heart disease.Methods In this cross-sectional study, 483 adolescents aged 12–17 were participated. Pittsburgh Sleep Quality Index and an Electronic Media Use Questionnaire were applied to assess sleep and screen pattern. Chi-square tests and regression analysis were employed to evaluate associations between screen exposure and sleep quality, with significance set at p<0.05.Results Of the 483 participants, 49.7% exhibited poor sleep quality. Poor sleepers reported significantly higher daily media duration and social media frequency compared to good sleepers. Logistic regression identified device usage before sleep (odds ratio OR=1.64, p=0.008), obsessive urge to use devices (OR=1.81, p=0.002), and next-morning tiredness (OR=1.73, p=0.006) as significant predictors of poor sleep quality.Conclusions Excessive and compulsive electronic media use, particularly before bedtime, significantly degrades adolescent sleep quality. Given the established link between sleep deprivation as an early cardiometabolic risk factor, the study founds limiting evening screen exposure creates a vital preventive cardiology strategy to mitigate the future burden of cardiovascular disease.
