Risk factors for work-related musculoskeletal disorders among workers in the footwear industry: a cross-sectional study
Abstract
The aim of the study was to investigate the influence of biomechanical, psychosocial, environmental and individual factors on local and multisite work-related musculoskeletal disorder (WMSD) symptoms among workers at a footwear manufacturing company. The sample comprised 267 workers. The results showed that: (a) age, sedentary lifestyle, inappropriate posture and perceived effort were associated with symptoms in the shoulders, and the combination of these factors increased the odds four-fold; (b) inappropriate posture, perceived effort and bullying were related to symptoms in the wrists, and the combination of these factors increased the odds seven-fold; (c) inappropriate posture, perceived effort, length of work at the company and low social support were associated with multisite symptoms, and their combination increased the odds up to 30-fold. Therefore, mainly biomechanical and psychosocial factors were associated with WMSD symptoms, and their combinations increased the odds of occurrence.
How strong is the evidence?
Evidence Hub reads this as a cross-sectional, done in people. Its evidence level is 4 of 5 (Low · observational). Observational designs can show an association but not prove cause.
