Abstract

Background
This study investigated the relationship between verbal aggression against school teachers and upper extremity (neck, shoulder, upper limb, and/or upper back) musculoskeletal pain.
Methods
This was a cross-sectional study of 525 elementary school teachers from Jaboatão dos Guararapes, Northeast Brazil.
Results
The prevalence of upper extremity musculoskeletal pain among teachers who reported verbal aggression in the past six months (67.7%) was higher than that among those who did not report verbal aggression (51.7%): (prevalence ratio = 1.21; 95% confidence interval = 1.04-1.40). The prevalence of upper extremity musculoskeletal pain was associated with verbal aggression, sex, and common mental disorders, controlled by skin color, age, monthly income, teachers' education, years working as a teacher, workload, and obesity. Furthermore, the measure of the association between verbal aggression and upper extremity musculoskeletal pain was modified by sex and common mental disorders, considered altogether. Teachers who suffered verbal aggression, of the feminine sex, and also having common mental disorders reported high prevalence (85.4%) of upper extremity musculoskeletal pain.
Conclusion
The association between verbal violence in the school and complaints of upper extremity musculoskeletal pain was strong and modified by teachers' sex and common mental disorders.
