Prevalence of musculoskeletal symptoms and associated factors: A cross-sectional study of metal workers in Bangladesh

Abstract

BACKGROUND: There is a scarcity of evidence regarding musculoskeletal symptoms prevalence among metal workers at different worksites in Bangladesh. OBJECTIVE: To determine the prevalence of musculoskeletal symptoms and associated factors among metal workers in Dhaka, Bangladesh. METHOD: This cross-sectional study was performed in 5 out of 12 randomly selected metal tools manufacturing factories in Dhaka, Bangladesh. A total of 60 eligible participants (45 male and 15 female) were asked to complete the short Bengali version of the Dutch Musculoskeletal Questionnaire. In addition, observations within the workplace were performed using a predesigned checklist for identifying ergonomic risk factors. RESULTS: Prevalence of musculoskeletal symptoms during the last 12 months preceding data collection was reportedly 85%. Body regions reported to be most affected were upper back and lower back, then the wrist. Socio-demographic factors were not found to be significantly associated with musculoskeletal symptoms. In contrast, awkward posture and repetitive movement were significantly related to reports of musculoskeletal symptoms for the last 12 months preceding data collection. CONCLUSION: Results conclude that there is a high reported prevalence of musculoskeletal symptoms among metal workers, calling for an action on prevention and promotion in the work environment.
