Abstract: BACKGROUND: The physical condition of workers’ body structure and assigned duties, can contribute to the prevalence of musculoskeletal disorders. OBJECTIVE: This study aimed to investigate the relationship between body structure status, type of work activity, and the prevalence of musculoskeletal disorders among workers in the detergent industry. METHODS: This cross-sectional study involved 148 industrial workers selected based on inclusion criteria and their medical checkup records. Data collection for the study included a demographic information questionnaire, a body map questionnaire, and an assessment of the workers’ musculoskeletal system conducted by three physiotherapists simultaneously. RESULTS: 54.1% of the participants had a total body structure score classified as poor or fair. The neck region showed the highest prevalence of musculoskeletal disorders (51.4%), followed by the lower back region (35.1%). Significant associations were found between abnormalities in the upper and middle limbs of the body and the prevalence of pain in the right shoulder region (Fisher/F = 9.29, P≤0.05) as well as the intermediate back region (F = 10.28, P≤0.01). Office workers experienced a higher prevalence of neck pain than workers in the product line and technical roles, with a statistically significant Odds Ratio (OR) ranging between 2.7 and 6.6 times. Conversely, industrial workers who operate powered machinery showed a higher prevalence of pain in the left shoulder (OR = 3.93) and left foot (OR = 4.07). Meanwhile, workers involved in loading and unloading tasks had a higher prevalence of pain in the middle back (OR = 3.61) and right foot (OR = 4.5) compared to office workers. CONCLUSIONS: The prevalence of pain in the right shoulder and middle back may be due to abnormalities in the upper and intermediate body structure. Production line workers reported a higher prevalence of pain in the left shoulder, middle back, and foot compared to office workers.
