Work with visual display units and musculoskeletal disorders: A cross-sectional study

Area of Science:

• Occupational Health
• Ergonomics
• Epidemiology

Background:

• Epidemiological studies indicate a higher incidence of musculoskeletal disorders (MSDs) among visual display unit (VDU) workers.
• Individual and work-related factors are suspected contributors to MSDs in this population.

Purpose of the Study:

• To evaluate the associations between MSDs and individual/work-related factors in VDU workers.
• To identify risk factors contributing to MSDs in the VDU workforce.

Main Methods:

• A study assessed 1032 VDU workers, collecting data on personal factors (age, smoking, activity) and work factors (job tasks, posture).
• Work environment compliance with ISO 9241-5:1998 was evaluated through direct observation of participants and workstations.
• Logistic regression analysis was used to calculate adjusted odds ratios (ORa) for MSD risk factors.

Main Results:

• The prevalence of MSDs was 53%.
• Significant associations were found between MSDs and female sex (OR=2.832), age ≥ 50 (OR=2.231), and extended VDU exposure (working history and time).
• Inappropriate workstation design was identified as a significant risk factor for MSDs (ORa=2.375).

Conclusions:

• MSDs in VDU workers are significantly linked to individual characteristics and work environment factors.
• Optimizing workstation design is crucial for reducing the prevalence of MSDs among VDU users.
