Abstract

Objective: To evaluate the association between ergonomic risks, musculoskeletal disorders (MSDs), and work-related fatigue in employees of three public libraries in Mexico City.

Materials and methods: A cross-sectional, analytical, and correlational study was conducted with 65 employees, selected using non-probability convenience sampling. A structured questionnaire was administered, and the EST-UNAM test was used to assess musculoskeletal hazards, the Yoshitake Test for work-related fatigue, and the Health and Safety Executive tool for workplace demand and control. Ergonomic risk identification was performed according to ISO/TR 12295.

Results: Ergonomic risks were identified among librarians. The results showed high ergonomic exposure, particularly in the Vasconcelos Library, where trunk postures reached 96%, repetitive movements 67%, and manual handling 63%. 87% of library employees were overweight or obese, and 32.3% experienced work-related fatigue. The main musculoskeletal complaints were related to the back, neck, and hand/wrist

Conclusions: The results demonstrate the presence of ergonomic factors and work-related fatigue, thus requiring comprehensive interventions aimed at improving ergonomic conditions and work organization.
