Background and Objectives: Computer Vision Syndrome (CVS) has become a major health problem among university students as a result of extensive electronic device use, but there is limited in-depth risk factor analysis by academic disciplines. The purpose of this study was to determine CVS prevalence, identify risk-associated factors, and investigate discipline-specific differences among university students. Methods: A cross-sectional study was conducted at Jazan University among 427 students of six academic disciplines between 2023 and 2024. Questionnaires validated by collecting demographics, electronic device usage patterns, eye care practices, and CVS symptoms were used to assess the data. Statistical analyses involved chi-square tests and multivariable logistic regression with significance at p < 0.05. Results: Prevalence of CVS was at epidemic proportions at 89.7% (95% CI: 86.8–92.6%), which was much higher than global averages. Considerable inter-disciplinary heterogeneity occurred, from 95.3% in Computer Science to 75.4% in Arts and Humanities students. A strong dose–response gradient was found for duration of device use: 3–4 h (OR = 4.13, 95% CI: 1.13–5.57), 5–6 h (OR = 5.31, 95% CI: 1.46–9.86), and ≥7 h per day (OR = 6.25, 95% CI: 1.74–8.01) versus 1–2 h use. Students >24 years old demonstrated a very high risk (OR = 9.73, 95% CI: 1.53–19.65). Headaches were the most common symptom (68.0%), and adoption of protective measures was low. Conclusions: This work demonstrates epidemic-level prevalence of CVS with unequivocal dose–response relationships and discipline-specific risk patterns, offering evidence-based targets for immediate campus-wide interventions and identifying a vital post-pandemic public health challenge meriting immediate attention.

Background/Objectives: Disc herniation, also termed herniated nucleus pulposus (HNP), is a common spinal disorder affecting approximately 10% of the global population, associated with pain, neurological complications, and diminished quality of life. Despite its global burden, regional variations in public awareness and sociodemographic determinants remain inadequately characterized, particularly in Middle Eastern populations. This study aimed to assess the prevalence, public awareness, and sociodemographic determinants of HNP among adults in Saudi Arabia at a nationwide level. Methods: An analytical cross-sectional study was conducted from December 2024 to July 2025. Using a convenience sampling approach via social media platforms, an online questionnaire was distributed nationwide across Saudi Arabia. Data from 1112 participants were analyzed using descriptive statistics and multiple logistic regression. The questionnaire comprised two sections: sociodemographic characteristics and knowledge and awareness of HNP. Results: The prevalence of disc herniation was 8.9%, consistent with global estimates. Overall awareness was relatively high at 67.6%, though knowledge of specific risk factors varied considerably. Most participants recognized obesity (88.0%), poor sitting posture (85.8%), history of lower back trauma (86.2%), and work requiring physical effort (88.8%) as risk factors, while fewer acknowledged smoking (46.4%), diabetes (51.2%), sleeping on a soft bed (36.9%), and increased height (35.9%). Multiple logistic regression, adjusted for all sociodemographic, lifestyle, and health-related covariates, identified significant independent predictors of HNP including marital status (married OR = 2.90), current smoking (OR = 2.91), hyperlipidemia (OR = 1.86), family history (OR = 8.95), and prior knowledge of the condition (OR = 2.28). Knowledge of HNP was significantly associated with university education (OR = 1.70), higher income levels (OR = 2.23 for ≥15,000 SAR; OR = 2.07 for 5000–9999 SAR), and family history (OR = 4.70), while those in low and medium workload jobs demonstrated lower knowledge. Conclusions: Although overall public awareness of HNP is relatively high in Saudi Arabia, substantial gaps persist in knowledge of modifiable risk factors, particularly smoking and diabetes mellitus. Targeted smoking cessation campaigns, diabetes awareness programs, and ergonomic education initiatives delivered through primary healthcare centers, workplaces, and schools are recommended.
