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.

sleep disturbance severity
Scale Used: Insomnia Severity Index (ISI) Description: The ISI is a 7-item self-report questionnaire that assesses the severity of insomnia and its impact on daily functioning. Each item is scored on a 0-4 scale, with total scores ranging from 0 to 28. Higher scores indicate more severe sleep disturbance.
Time frame: 1 day
body awareness
Scale Used: Q-BAPHYP Description: The body awareness component of the Q-BAPHYP scale assesses an individual's awareness of their body position, movement, and physical sensations. It may include items related to: Recognition of poor posture Awareness of physical discomfort during screen use Sensitivity to bodily signals (e.g., fatigue, muscle tension) Attention to ergonomic positioning
Time frame: 1 Day
Pediatric Quality of Life
Scale Used: PedsQL™ (Pediatric Quality of Life Inventory) Description: The PedsQL™ is a modular instrument designed to measure health-related quality of life in children and adolescents. It covers multiple dimensions of well-being across: Physical Functioning (e.g., ability to engage in physical activities) Emotional Functioning (e.g., feeling anxious or sad) Social Functioning (e.g., interactions with peers) School Functioning (e.g., ability to concentrate and attend school)
Time frame: 1 Day
Postural Habits
The body awareness component of the Q-BAPHYP scale assesses an individual's awareness of their body position, movement, and physical sensations
Time frame: 1 Day
