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.

Disorders of the Skeletal Muscle
Musculoskeletal disorders
Musculoskeletal disorders involve injuries and conditions affecting the skeletal muscles and associated connective tissues. These disorders can arise from acute biomechanical stresses or chronic overuse and can occur across different age groups. Common injuries include sprains, fractures, and muscular strains, often resulting from...
Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
