Abstract:
Background: Egyptian Generation Z adolescents are heavily engaged with screens for several purposes, including education, entertainment, social media, and gaming. This raises red flags about how screen culture may affect sleep quality, posture-related habits, and health-related quality of life. Objectives: To examine how different types and amounts of weekday and weekend screen time are associated with symptoms of insomnia, body awareness of postural habits, and health-related quality of life among Egyptian Generation Z adolescents. Materials and Methods: A cross-sectional English-language online survey was completed by a self-selected convenience sample of Egyptian adolescents aged 13-18 years from multiple governorates; 530 participants were included in the analysis. Participants reported total screen time, the Insomnia Severity Index, Body Awareness of Postural Habits questionnaire, and the Pediatric Quality of Life Inventory. Multiple linear regression models were adjusted for age, gender, body mass index, level of education, and place of residence. Results: After false-discovery-rate adjustment across 30 comparisons, 13 activity-specific associations met the significance threshold. Higher ISI scores were associated with weekday job or internship-related use, weekday and weekend entertainment use, and weekday and weekend social-media use. Lower Q-BAPHYP scores were associated with weekday and weekend entertainment and social-media use. Lower PedsQL scores were associated with weekday job or internship-related use, weekday entertainment use, and weekday and weekend social-media use. The models explained limited variability in the outcomes. Conclusions: The screen use of Egyptian Generation Z adolescents is associated with insomnia, postural awareness, and overall quality of life; additional unmeasured factors probably influence such outcomes as well.
