Screen Culture's Impact on Generation Z Adolescents' Physical Activity, Posture and Well-being in Egypt
An observational study of Adolescence and Adolescent, run by Sinai University at 1 site in Egypt.
Trial 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. Read more about this study

About this study
Official title: Screen Culture's Impact on Generation Z Adolescents' Physical Activity, Posture and Well-being in Egypt: A Cross-sectional Study
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.

What is being measured
The primary outcome is the main question the study is designed to answer.
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.
Measured: 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
Measured: 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)
Measured: 1 Day
Secondary outcomes (1)
Postural Habits
The body awareness component of the Q-BAPHYP scale assesses an individual's awareness of their body position, movement, and physical sensations
Measured: 1 Day
