Work-related musculoskeletal disorders and risk factors among weavers: A cross-sectional study.

Background: Work-related musculoskeletal disorders (WRMSDs) are a major health issue for low-income countries because of their high prevalence among workers and on account of the scarcity of ergonomic preventative measures in the workplace.

Objectives: To determine the prevalence of WRMSDs among weavers, assess their consequences, and analyse the associated occupational risk factors.

Method: A cross-sectional survey was carried out among 257 handloom weavers using the Nordic questionnaireand the working conditions were assessed through a descriptive analysis using the key indicator method.

Results: The WRMSDs annual prevalence was 85% in all parts of the body, 71% for the low back region, 41% for the shoulders, and 37% for the knees. One quarter of the weavers indicated having stopped work for 1-30 days because of their low back pain (LBP). The prevalence of WRMSDs was associated with the number of hours worked per day, the years of experience, and age. Long working hours, load carrying (> 20 kg - 25 kg), awkward postures, repetitive limb movements, and unfavourable environmental conditions were identified as occupational risk factors.

Conclusion: Work-related musculoskeletal disorders are common among weavers and LBP is the most frequently cited disorder and the primary reason for work interruptions and a decrease of activities. The prevalence of WRMSDs is associated with professional and personal factors. Actions based on ergonomic rules are necessary to prevent WRMSDs.

Clinical implications: Our study highlights the issue of WRMSDs and the need for prevention in the informal sector, which constitutes the major part of economic activity in low-income countries.
