Background: Musculoskeletal disorders (MSDs) are a common problem among carpet weavers. This
study was undertaken to introduce affecting personal and occupational factors in developing the number
of MSDs among carpet weavers.
Methods: A cross-sectional study was performed among 862 weavers in seven towns with regard to
workhouse location in urban or rural regions. Data were collected by using questionnaires that contain
personal, workplace, and information tools and the modified Nordic MSDs questionnaire. Statistical
analysis was performed by applying Poisson and negative binomial mixed models using a full Bayesian
hierarchical approach. The deviance information criterion was used for comparison between models and
Results: The majority of weavers (72%) were female and carpet weaving was the main job of 85.2% of
workers. The negative binomial mixed model with lowest deviance information criterion was selected as
the best model. The criteria showed the convergence of chains. Based on 95% Bayesian credible interval,
the main job and weaving type variables statistically affected the number of MSDs, but variables age, sex,
weaving comb, work experience, and carpet weaving looms were not significant.
Conclusion: According to the results of this study, it can be concluded that occupational factors are
associated with the number of MSDs developing among carpet weavers. Thus, using standard tools and
decreasing hours of work per day can reduce frequency of MSDs among carpet weavers.
