Mental distress in workers at two metallurgical companies in the state of São Paulo, Brazil.

This study aimed to map the prevalence of mental distress among employees at two metallurgical companies and to analyze differences according to the sex of workers and the employing company. An analytical cross-sectional study was conducted using the 20-item Self-Reporting Questionnaire to map the prevalence of mental distress. A total of 439 workers participated in the study. The overall prevalence was 10.0%, being 4 times higher in women (32.3%) than in men (8.3%) (p < 0.001). There was no significant difference between the prevalence rates of mental distress according to employing company (p = 0.271) or sector (p = 0.239). The most frequent complaint was 'nervousness, tension, and worry' (48.7%). These results indicate the need for management of workers' mental health, especially among women.
