Summary
This cross-sectional study found that rotating night shift workers showed statistically significant negative changes in visual evoked potential parameters compared to day workers, suggesting circadian disruption may impair the visual pathway over time. These findings are relevant for occupational health planning in healthcare facilities, indicating that prolonged night shift schedules may have underappreciated neurological and visual consequences for staff.
Key Findings
- Rotating night shift workers (>6 months) showed statistically significant changes in VEP latency and amplitude compared to non-night-shift controls (p < 0.05).
- Pearson correlation indicated that as head circumference increased, VEP latency increased and amplitude decreased.
- Study sample: 80 security guards aged 20â40, split into 40 night-shift and 40 day-shift workers.
