Psychosocial Factors, And Ergonomic Analysis Musculoskeletal Symptoms Management Personnel In A Public University

Abstract

Introduction. Musculoskeletal disorders have increased exponentially, affecting various occupations, including administrative staff exposed to prolonged postures and repetitive movements. This study aimed to evaluate psychosocial factors, ergonomic conditions, and their relationship to musculoskeletal symptoms among administrative staff at a public university. Methods. A cross-sectional study with an ergonomic approach and mixed design was conducted. The sample included 149 employees (71% women, 29% men) from 22 departments. Voluntary consent was obtained. The Nordic Questionnaire of Musculoskeletal Symptoms, the Copenhagen Psychosocial Questionnaire (ISTAS 21), and the Helsinki Method for ergonomic assessment were used. Data were analyzed using SPSS 19.0. Results. The average age was 39 years, with 29% overweight and an average tenure of 9 years. Musculoskeletal symptoms were reported in the neck (78%), right shoulder (38%), back (36%), and right wrist (42%). Adverse psychosocial risks included "psychological requirements," "insecurity," "double presence," and "esteem," while favorable factors were "active work," "development potential," and "social support and quality of leadership." The ergonomic analysis indicated a trend of 4 (very inadequate) in workplace design. Conclusions. Musculoskeletal symptoms are highly prevalent, particularly in the neck, shoulders, back, and wrists. Adverse psychosocial conditions and poor ergonomic design contribute to these issues. While some positive psychosocial aspects were observed, it is necessary to optimize job positions through ergonomic interventions and stress management strategies to reduce these risks and improve working conditions.
