Work-Related Musculoskeletal Disorders: A Systematic Review and Meta-Analysis

background: musculoskeletal disorders (MSDs) involve muscles, nerves, tendons, joints, cartilage, and spinal discs. these conditions can be triggered by both the work environment and the type of work performed, factors that, in some cases, can also exacerbate pre-existing conditions. this systematic review aims to provide an overview of the impact that different work-related activities have on the musculoskeletal system. tmethods: a global search of publications was conducted using the following international bibliographic web databases: pubmed and web of science. the search strategies combined terms for musculoskeletal disorders and workers. In addition, a meta-analysis was conducted to estimate the prevalence of MSDs within the healthcare sector. results: a total of 10,805 non-duplicated articles were identified, and finally, 32 studies were reviewed in this article. once the literature search was completed, occupational figures were categorized into healthcare, farming, industrial, and computer sectors. In the healthcare sector, the prevalence estimate for degenerative diseases of the lumbar spine was 21% (497 out of 2547 physicians and dentists) (95% CI, 17-26%), while for osteoarthritis of the hand, it was 37% (382 out of 1013 dentists) (95% CI, 23-51%). conclusions: musculoskeletal disorders significantly impair workers' quality of life, especially in healthcare sector. these conditions are also associated with high costs for employers, such as absenteeism, lost productivity, and increased costs for healthcare, disability, and workers' compensation.
