Evaluation of Related Risk Factors in Number of Musculoskeletal Disorders Among Carpet Weavers in Iran

Abstract

BackgroundMusculoskeletal 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.MethodsA 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 model selection.ResultsThe 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.ConclusionAccording 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.

Determining the Prevalence of Musculoskeletal Disorders in Tailors in Kermanshah, Iran Using the Nordic Questionnaire (2018)

“…Non-ergonomic conditions of the work environment and incorrect conditions of the body during the work had caused high levels of MSDs. The discrepancy of results observed in different studies can be explained by the differences in factors such as age range, gender, sample size and work experience (29,30). Corrective measures are therefore required to lower the high risk associated with these disorders.…”

Risiko Ergonomi dan Keluhan Musculoskeletal Disorders (MSDs) pada Pengrajin Tenun di Palembang

“…Hal ini sesuai dengan penelitian yang dilakukan pada pengrajin tenun karpet di Iran yang menyatakan bahwa faktor usia, jenis kelamin, dan masa kerja tidak berpengaruh terhadap keluhan MSDs. 28 Walaupun hasil analisis multivariat menunjukkan tidak adanya pengaruh dari faktor jenis kelamin, usia, dan masa kerja terhadap keluhan MSDs tetapi banyak penelitian lain yang menunjukkan hal sebaliknya. Penelitian yang dilakukan pada pengrajin tenun lakilaki di Bangladesh menunjukkan bahwa terdapat hubungan yang siginifikan antara usia dan masa kerja dengan keluhan MSDs.…”

Musculoskeletal pain and associated factors among waste collectors in Hanoi, Vietnam: A cross-sectional study.

“…MSDs are the leading cause of disability (2), result in impairing body function, affecting the workers' quality of life and reducing their working capability (3), which in turn will have significant economic ramifications for the workers (1). Although high prevalence of MSDs has been reported in various occupations (3)(4)(5)(6)(7)(8)(9)(10)(11), many employees with pain have to keep working for a living, hence continuously expose to specific occupational hazards which aggravate their pain conditions. Evidence on factors of persistent musculoskeletal pain is needed to develop effective prevention and control measures.…”

“…the neck/back bent for a prolonged time at an angle of over 45º without supportive equipment, medial rotation while walking and carrying >5kg with one hand) would elevate the risk of persistent MSDs. Empirical evidence was available to support the association between the increased risk of MSDS and poor working postures, quick motion and continuous bending or twisting while carrying or lifting heavy objects(1,7,10,26).…”
