Introduction:
Musculoskeletal disorders are the most common occupational disease in the world. They constitute a major health problem.
Methods:
A cross-sectional study was carried out over a period of three months involving the secretaries of the Yopougon University Hospital. The data were collected using a questionnaire inspired by the National Research and Security Institute (INRS) questionnaire.
Results:
The study found an exclusively female population with an average age of 40.6 years ± 8.6, mostly overweight or obese (71%). Almost half of the secretaries had more than ten years of seniority in the post (44.7%) and the absence of an ergonomic chair was noted in 84% of cases. In this population of 38 secretaries, the prevalence of MSDs was 89.5% with pain as the main symptom (89.5%). The preferred locations for MSDs were the dorsolumbar spine (78.9%) and the cervical spine (57.9%). The study showed a predominance of MSDs in the following populations: overweight secretaries (63.1%); more than ten years in the post (39.6%); poor working posture (68.4%); the use of a non-ergonomic seat (81.6%).
Conclusion:
Musculoskeletal disorders are common among secretaries. They are associated with many factors. It is imperative to implement preventive measures to reduce their risk of occurrence.

The Functions of the Skeletal System
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...

Components of the Skeletal System
Bone, or osseous tissue, is a hard connective tissue that forms an internal support structure for the human body. Bones shield vulnerable organs and soft tissue from external forces. For example, the vertebral bones protect and support the spinal cord.

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...
