ABSTRACT
BACKGROUND: Work-related musculoskeletal disorders are one of the most common public health problems throughout the world. It is a major cause of occupational injury, illness, and disability that leads to an increased rate of sick leave, financial costs for both individuals and society and the health care system. Weavers are among the populations exposed to musculoskeletal disorders due to a lack of occupational safety, health services, and poor working conditions. Yet, little is known about WMSD among weavers in Africa particularly in Ethiopia. Thus, this study aimed to assess the prevalence and associated factors of work-related musculoskeletal disorders among weavers. METHOD: A multi-centered institutional-based cross-sectional study was conducted in Bahir Dar City, Ethiopia among 424 weavers with a response rate of 97.7%. Participants were recruited randomly after proportional allocation was done for each institution and face-to-face interviews were employed to collect data using a well-structured questionnaire adopted from the Nordic musculoskeletal questionnaire and different literature. The data were entered into Epidata and analyzed using SPSS version (Choobineh A, Lahmi M, Shahnavaz H, Khani Jazani R, Hosseini M. Int J Occup Saf Ergon, 10:157-68, 2004). Variables with a P-value < 0.25 in the bivariate logistic regression were entered into a multivariable logistic regression model. Finally, variables with an AOR, a 95% confidence interval, and a P-value of < 0.05 were reported. RESULT: The annual prevalence rate of work-related musculoskeletal disorders among weavers was 76.3% [CI = 72.2 to 80.2%]. Longer working hours [AOR = 3.48, CI = (1.96-6.21)] lack of back support during sitting [AOR = 2.50 (1.293-4.480)], having repetitive movement in weaving [AOR = 4.11(2.029-8.324)], attaining awkward posture [AOR = 3.37(1.875-6.059)] and job stress [AOR = 4.37(2.447-7.816)] was significantly associated with work-related musculoskeletal disorders. CONCLUSIONS: This study revealed a high prevalence of WMSDs among weavers. Our study findings reported that longer working hours, lack of back support during sitting, having repetitive movement in weaving attaining awkward posture, and having job stress were significantly associated with work-related musculoskeletal disorders.
