Prevalence of Work-related Musculoskeletal Symptoms among Iranian Workforce and Job Groups

Musculoskeletal disorders (MSDs) are known to cause occupational injuries. This study aimed to collate the existed relevant data and develop a general feature of MSDs problem among Iranian workforce.

In this study, we used the raw data related to 8004 employees from 20 Iranian industrial settings distributed throughout the country. In all studies, participants were selected based on simple random sampling method, and the data were collected using demographic characteristics and Nordic MSDs questionnaires.

The most prevalent MSDs symptoms were reported in the lower back (48.9%), shoulders (45.9%), neck (44.2%), upper back (43.8%), and knees (43.8%). Prevalence rates of MSDs at least in one body region were found to be the highest (90.3%) among health-care workers. Prevalence rates of MSDs symptoms in all body regions were higher among workers with dynamic activities as compared to those of workers with static activities.

MSDs symptoms were common among the study population. Health-care provider and workers with dynamic activities had the highest rate of MSDs. These results merit attention in planning and implementing ergonomics interventional program in Iranian industrial settings.
