Prevalence of Work Related Musculoskeletal Disorders and Associated Factors Among Bank Staff in Jimma City, Southwest Ethiopia, 2019: An Institution-Based Cross-Sectional Study

BACKGROUND: Work-related musculoskeletal disorder is one of the most important public health problems throughout the world. However, there is a paucity of knowledge on work-related musculoskeletal disorders among bank staff in Ethiopia. Therefore, this study aimed to assess the prevalence of work-related musculoskeletal disorders and associated factors among bank staff in Jimma city, Ethiopia. METHODS: Institution-based cross-sectional study was conducted from July 20 to August 20, 2019. A simple random sampling technique was used. Data were collected by pre-tested interviewer-administered standardized Nordic musculoskeletal questionnaires. Data were entered into Epi Data version 3.1 and exported to SPSS version 20 for analysis. A logistic regression analysis was done. A variable having a p-value <0.25 in a bivariate analysis was taken into multivariate analysis to avoid the potential effects of confounders. Adjusted odds ratios (AOR) were calculated at a 95% confidence interval to see the strength of association. A significant association was set at a p-value <0.05. RESULTS: Data were collected from 335 study participants. The overall prevalence of work-related musculoskeletal disorders during the last 12-months was 245 (73.1%). The most affected body parts were lower back 181 (54%), neck 152 (45.4%), upper back 143 (42.7%), and shoulder 127 (37.9%). Work experience [AOR: 2.16, 95% CI: 1.05–4.43], alcohol consumption [AOR: 3.44, 95% CI: 1.29–9.18], awkward posture [AOR: 4.09, 95% CI: 2.20–7.61], working in the same position for two or more hours [AOR: 2.02, 95% CI: 1.05–3.89] and job stress [AOR: 3.20, 95% CI: 1.67–6.15] were factors associated with work-related musculoskeletal disorders. CONCLUSION: The prevalence of work-related musculoskeletal disorders was common among bank staff. Preventive strategies such as using ergonomic guidelines and giving awareness on the effect of bad posture, avoiding prolonged working in the same position were recommended. Using ergonomic guideline is helpful to create a suitable working environment that fit employee’s physical capability.
