Summary

Ubiquitous adoption of screen-based technologies has transformed the behavioral and physiological environment of Generation Z youth. In Egypt, where digital adoption speeds up with apace urbanisation, teens (13-18) have greater exposure to computers, mobile phones, and other screen-based devices. Growing evidence points towards excessive viewing of screens in compromised well-being, including sleep issues, inactive lifestyles, weight loss/gain, and musculoskeletal disturbances. Contextual evidence for the Egyptian teenager is scarce. This study fills the gap by investigating the multi-dimensional influence of screen culture on physical well-being, focusing on sleep quality, body mass index (BMI), posture, physical activity, and disability outcomes.
