Objectives: This study aims to fill this gap by evaluating sewing workstations and analyzing the prevalence of work-related musculoskeletal disorders and associated risk factors for operators in case company. Methods: The sample included 217 sewing machine operators. Data were collected through standardized Nordic MSDs questionnaire and strain index tool for distal upper extremities on selected garment workers. And also using logistic regression analysis were used to identify the factors that influence the prevalence of work-related Musculoskeletal disorders and associated risk factors for operators. Result: The result showed that the prevalence rate for Musculoskeletal pain in different body regions was 93.9% in the low back, 93.3% in the upper back, 76% in the neck, 65.4% in the hip/thigh/ and buttocks, 52.0% in the shoulder, 45.8% in the elbow, 40.2% in the wrist or hand, 33% in the knee and 36.9% in the ankle or feet. Moreover, the Strain Index (SI) score indicates hazardous (57%) and some risk (29%), uncertain (21.7%), and probably safe (3.5%) of upper extremity disorders during performing their tasks. Conclusion: After analysis of the data using regression models, the result revealed that the suitability of the sitting chair with the sewing workstation, the comfort of the working environment, job satisfaction, medical history in the previous 12 months related to MSDs, working experience, education level, and gender were the most significant factors associated with the prevalence of WRMSDs among various body parts. The finding revealed the workstation of sewing machine operator and emphasized the need for ergonomic interventions to minimize the MSDs among them.
