Abstract: (3251 Views)
Objectives: Work-related musculoskeletal disorders are multifactorial conditions that result in time loss, disability, and increased economical costs. The aim of the current study was to evaluate the role of the physical, environmental and psychosocial factors in the development of musculoskeletal disorders in workers in the production and assembly of auto parts in Qom city in 2021.
Methods: In this cross-sectional study, 211 participants through an inconvenience sampling method entered the study. The demographic characteristics of participants and the prevalence of musculoskeletal disorders were assessed by a self-report questionnaire and the Extended Nordic questionnaire, respectively. The mental workload was evaluated by the NASA-TLX index and the physical, environmental and psychosocial risk factors were evaluated by the Structured Multidisciplinary Work Evaluation Tool (SMET). The binary logistic regression method was used to show the role of the different risk factors in the development of MSDs.
Results: Participants had an average age of 33.9 years (SD = 6.9). The lifetime prevalence of MSDs was obtained at about 77.72% in at least one area of the body. The neck, back, and shoulder areas were the most common regions. Gender, smoking history, surgery history, age, past surgery history, and sports history were most effective in the development of MSDs. In addition, subscales of mental workload play a role in causing pain in the shoulders, upper back, back and knees. SMET subscales play an effective role in the neck (OR = 1.396), upper back (OR = 1.663), hip, and knee, wrist/hand, and ankle/foot pain.
Conclusion: According to the role of various factors in developing disorders, the physical, psychosocial, and environmental factors should be considered simultaneously in planning preventive programs and ergonomics interventions.
