Abstract
BACKGROUND: When performed in unfavorable conditions, work can lead to the development of musculoskeletal disorders and decrease in work ability. OBJECTIVES: To identify the differences between three groups of workers (professors, technicians and outsourced workers) as for the sociodemographic profile, work ability, prevalence of musculoskeletal disorders, activity restrictions, and the correlation between the presence of musculoskeletal disorders and activity restrictions with each domain of the Work Ability Index. METHODS: The sample consisted of 67 university workers assessed by a Sociodemographic Data Questionnaire, the Nordic Musculoskeletal Symptoms Questionnaire and the Work Ability Index. Descriptive statistics and Kendall's Tau correlation coefficient were used. RESULTS: Professors presented more favorable sociodemographic and lifestyle aspects and higher work ability, while outsourced workers had less favorable sociodemographic and lifestyle aspects and lower work ability. The correlation between activity restrictions and work ability was found in only one domain of Work Ability Index among professors. Among outsourced workers were found correlations on presence of musculoskeletal disorders and activity restrictions with six domains of Work Ability Index. Technicians did not show significant correlation. CONCLUSIONS: Outsourced workers presented worse work ability and less favorable sociodemographic and lifestyle aspects among the workers in the study, requiring the maintenance and improvement of work ability in this population.
