Background: Today, millions of computer users around the globe have musculoskeletal disorders (MSDs), highlighting the significant rise in office employees experiencing these conditions and the urgent need for intervention.
Objective: To investigate the ergonomic risk factors and their relationship with musculoskeletal disorders among computer-using administrative staff in a Nigerian University.
Methods: A cross-sectional study of 142 administrative staff of Redeemer's University, Ede, Nigeria, was conducted. Data on respondents' general characteristics were gathered through a self-developed questionnaire. Data on MSDs were derived from the Nordic Musculoskeletal Questionnaire (NMQ), while ergonomic data were collected using the Rapid Office Strain Assessment (ROSA) method.
Results: The highest prevalence rates of MSDs were in the neck (51.4%) and lower back (42.3%) regions. The mean ROSA score at workstations for the chair section was 5.01±1.35, the monitor and telephone section was 2.54±1.05, and the mouse and keyboard section was 2.73±0.84. The mean final ROSA score was 5.06±1.32, indicating that most of the employees were at high risk of musculoskeletal complaints. The chair section was identified as the most significant factor raising the risk level. There was a significant positive and moderate correlation between ROSA final score and MSDs at the neck (r = 0.469) and low back (r = 0.309).
Conclusion: MSDs are prevalent among computer-using office workers, and there is a significant relationship between MSDs and workstation ergonomics. The parameters associated with the chair section should receive priority attention to reduce and eliminate MSDs among university administrative staff who use computers.
