Screen Culture's Impact on Generation Z Adolescents' Physical Activity, Posture and Well-being in Egypt

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.

Treatment and study plan

BMI Measurement

Diagnostic Test

BMI Measurement: Self-report height/weight (compared with age/sex standard BMI percentiles).

Screen Time Questionnaire (QUEST)

Diagnostic Test

Screen Time Questionnaire (QUEST): Assess length, purpose, and pattern of device use.

Insomnia Severity Index (ISI)

Diagnostic Test

Insomnia Severity Index (ISI): 7-item sleep disturbance severity measure (score range: 0-28).

Q-BAPHYP

Diagnostic Test

Q-BAPHYP: 20-item scale measuring body awareness, postural habits, and ergonomic behaviors.

PedsQL™

Diagnostic Test

PedsQL™: Pediatric Quality of Life Inventory

Primary outcomes

  1. sleep disturbance severity

    Time frame: 1 day

    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.

  2. body awareness

    Time frame: 1 Day

    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

  3. Pediatric Quality of Life

    Time frame: 1 Day

    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)

Secondary outcomes

  1. Postural Habits

    Time frame: 1 Day

    The body awareness component of the Q-BAPHYP scale assesses an individual's awareness of their body position, movement, and physical sensations
