Relación entre el uso de pantallas y la calidad de sueño en estudiantes de bachillerato de la Unidad Educativa Fiscomisional Río Santiago, cantón Limón Indanza - Ecuador 2024–2025.

Abstract

Background: The use of screen devices has increased significantly, affecting the sleep quality of young people, as screen use before bedtime drastically reduces the recommended 8 hours of sleep. Objective: To examine the relationship between screen use and sleep quality among high school students at the Río Santiago Government-Subsidized Educational Unit in the canton of Limón Indanza, Ecuador, during the 2024–2025 academic year. Methodology: A non-experimental, descriptive observational study was conducted with 151 high school students at the Río Santiago Educational Unit. Two surveys were administered: the Pittsburgh Sleep Quality Index and a questionnaire on screen use. The data were analyzed using SPSS, and Pearson correlation and independent-samples t-tests were employed. Results: Of 151 adolescents, 51% were female, and 49% were male; 92% were between the ages of 15 and 18. A positive correlation was found between screen use and sleep quality (p=0.005). Males reported higher screen use (p=0.006), and females had poorer sleep quality (p=0.009). Conclusions and relevance: It was concluded that there is a relationship between the variables: as screen use increases, sleep quality worsens among adolescents. There is a need to educate about adolescents sleep hygiene as well as the consequences of prolonged screen use; therefore, additional studies should be conducted in larger populations to confirm the results.
