EPIDEMIOLOGICAL ANALYSIS OF WORK-RELATED MENTAL DISORDERS ACCORDING TO GENDER AND AGE GROUP IN BRAZIL AND PARANÁ BETWEEN 2015 AND 2025

Abstract

The psychological illness results from the combined effect of personal factors, occupational demands, and institutional neglect in addressing mental health, leading to chronic stress with cortisol secretion and cognitive exhaustion, resulting in Burnout, generalized anxiety, and depression. The main objective of this study is to analyze work-related mental disorders in the context of gender and age group using data from Brazil and Paraná (2015 to 2025) extracted from SINAN/DATASUS and SmartLab. Data collection filtered the variables Sex, Brazil, Paraná, and Age group. Between 2015 and 2025, the country recorded 26,685 notifications, distributed heterogeneously with a predominance of adults aged 35 to 49 years (48.80% nationwide and 40.11% in Paraná), followed by those aged 20 to 34 years (32.70% nationwide and 36.68% in Paraná). Females were the most affected in all regions, totaling 18,173 cases in Brazil (68.10%) and 962 cases in Paraná (73.21%), a pattern associated with multiple work shifts, domestic workload, and lower healthcare-seeking behavior among men in primary care. Data from INSS/SmartLab revealed a predominance of anxiety disorders (30.3%), severe stress reactions (28.2%), and depressive episodes (23.7%). To control this condition, monitoring and training primary healthcare teams, combined with adequate epidemiological and governmental support, reduce the rate of new cases and improve the quality of life of affected individuals.
