Prevalence of Musculoskeletal Disorders and Associated Factors among View Screen Workers in Benin In 2020

Introduction: Musculoskeletal disorders (MSDs) are a real health problem at work. They drastically affect workers on the display screen. Objective: Studying the prevalence and associated factors of MSDs among workers on display screens in Benin.

Methodology: This was a cross sectional, analytical, descriptive study carried out from October 1 to December 31, 2020, among workers on display screens in Benin. The sampling was non-probability. The data collected were analysed using R software version 3.6.1. The comparison of frequencies was made using the Chi2 test. In multivariate analysis, a multiple logistic regression was carried out to find the associated factors. An odds ratio (OR) with a 95% confidence interval (95% CI) was calculated. A p ≤ 0.05 was considered statistically significant.

Results: The overall prevalence of MSDs was 93.1%. For the neck, upper back, lower back, shoulders, elbows and left right wrists, the prevalence was 69.9%, 70.3%, 77.3%, 46.1%, 34%, 8%, 20.7%, 16.8%, 45.7%, 26.2% respectively. Factors associated with MSDs were the use of a bad keyboard (p=0.028), use of corrective lenses (p=0.048), female gender (p=0.039), symptoms of stress type: cardiovascular disorders (p=0.001), gastrointestinal disorders (p=0.008), anxiety (p=0.031) and anxiety (p=0.035).

Conclusion: This study shows a high prevalence of MSDs among workers on display screens in Benin. The implementation of appropriate preventive measures could help reduce this prevalence.
