Objective: The study aimed to map the epidemiological profile of chronic musculoskeletal disorders and the ergonomic risks of body posture in the office environment. Methods: Data were collected using an electronic form consisting of sociodemographic questions and adapted versions of the Nordic Musculoskeletal Symptom and Rapid Office Strain Assessment questionnaires. Results: The mean age of the 73 participants in the extension project was 25.3 years and most had higher education. Of these, 86.3% felt pain, numbness or tingling in the last 12 months and of these, 90.5% had more than one body part affected by the symptoms. Of the thirteen body postures evaluated (sitting, leaning, position of the knees, feet, elbows, forearms and head), all were identified as ergonomically inadequate, especially those related to the chair used. Conclusion: There is a clear need for immediate health care actions for this population, since the office environments were not ergonomically adequate and the workers were already ill. Ergonomic intervention and health education actions are essential to guide the risks of this environment and propose behavioral changes to reduce/prevent musculoskeletal disorders. A limitation of the study may be that the sample was affected by the healthy worker effect, that is, those who were already affected by chronic musculoskeletal disorders were interested in participating in the project.
