In this study, we examined the relationship between screen time use, sleep characteristics, daytime somnolence, and academic performance in school-aged adolescents. We surveyed 1,257 12- to 18-year-old adolescents attending 52 schools urban or suburban areas of Argentina. recorded daily exposure various screen-based activities, including video- online-gaming, social media, TV streaming. Screen device type hour before bedtime, patterns during weekdays weekends, somnolence (Pediatric Daytime Sleepiness Scale score), grades language mathematics were also assessed. Structural Equation Modelling was used identify a path connecting latent variables. Results are expressed as standardized regression weights (srw). Missing data present 393 subjects, thus final sample consisted 864 complete responses. (i.e., PDSS score ≥ 15) observed 614 participants (71%), failure < 7/10) 352 them (41%). Time spent using video gaming consoles negatively associated with duration (srw = -0.22, p<0.01) positively connected 0.11, p<0.01). Use mobile devices lower -0.11, Sleep inversely related -0.27, p<0.01), which turn -0.18, p<0.05). Bedtime computer use did not influence any outcome. summary, among adolescents, adversely affected nighttime sleep, performance. These findings call for implementation educational public campaigns aimed at promoting healthy reducing
