Identifying individual and work-related risk factors of musculoskeletal disorders in an industrial organization

Musculoskeletal disorders (MSDs) are the main causes of work related injuries and disabilities in developed as well as developing countries. Few studies have considered different interactive effects of individual and work-related factors on MSDs، simultaneously. Methods and Materials: Data were gathered by Nordic questionnaire and Quick Exposure Check (QEC) method; and were analyzed using logistic regression model in order to study the correlation between the prevalence and intensity of MSDs and individual and work-related factors. More than half of all participants (61. 6%) reported suffering from one form of MSDs during the past 6 months. Results showed that risk factors such as work stress، sleeping position، lifestyle and poor posture had an important role in the prevalence and intensity of MSDs. The effect of a risk factor is constantly in interaction with other risk factors، and is modified by other factors. Participatory ergonomic intervention programs، work station intervention، ergo stress intervention and life-style interventions were suggested in order to decrease the prevalence and intensity of MSDs.
