Abstract

Lower back pain is a common occurrence among mine workers due to the nature of their work. Globally, workplace (occupational) and ergonomic risk factors have been reported to influence the prevalence of lower back pain among workers. This study aimed to determine ergonomic risk factors associated with lower back pain and associated risk factors (workplace and ergonomics) among mineworkers in a nickel mine in Zimbabwe. A cross-sectional study design was employed, and participants were randomly selected to complete a questionnaire that included the Dutch Musculoskeletal Questionnaire (DMQ). A total of 420 mine workers were interviewed, with the majority being male (n = 259, 61.7%) and aged between 31 and 44 years old (n = 159, 37.9%). The study found that the prevalence of lower back pain was 41.43% (n = 174). Several risk factors were found to be associated with lower back pain, including working overtime (AOR = 1.13, p < 0.01; 95% CI: 0.07–0.22), performing repetitive tasks (AOR = 8.06, p < 0.01; 95% CI: 4.67–13.93), bending (AOR = 7.77, p < 0.01; 95% CI: 3.97–15.22), and twisting (AOR = 3.32, p < 0.01; 95% CI: 1.83–6.03). Based on these findings, it is recommended that an ergonomic risk assessment and prevention program be implemented, which should include educational awareness about lower back pain and its prevention among mine workers.
