Introduction:

Work-related musculoskeletal disorders are injuries resulting from the excessive use of the musculoskeletal system. This study analyzed musculoskeletal symptoms and associated factors in primary school teachers in the municipal public network in Cuiabá, Mato Grosso.

Methods:

A cross-sectional study was conducted with 326 teachers. Data collection instruments included the Vocal Production Condition, Self-Reporting Questionnaire, and Nordic Musculoskeletal Questionnaire. The dependent variable was the presence or absence of musculoskeletal symptoms. Bivariate analysis using chi-square test and prevalence ratios with 95% confidence intervals, as well as multiple analysis using Poisson regression model, were performed.

Results:

In the multiple analysis, it was found that the presence of musculoskeletal symptoms was significantly associated (p<0.05) with the following risk factors: common mental disorders (PRa=1.45), regularly lifting weights (PRa=1.26), and performing intense physical effort (PRa=1.22). Additionally, a significant association was identified between these symptoms and contracted teachers (PRa=0.82), as well as an interaction between performing intense physical effort and regularly lifting weights (PRa=0.75), which acted as protective factors for symptom presence.

Conclusion:

It is concluded that work characteristics were important risk factors for the development of musculoskeletal symptoms in the last twelve months. The results of this study are believed to provide a basis for decision-making by managers and stakeholders in implementing preventive measures in the work environment of these teachers.
