Prevalence of minor psychiatric disorders among primary healthcare workers in the South and Northeast regions of Brazil

Mental health problems are among the most prevalent conditions in health workers. We evaluated the prevalence of minor psychiatric disorders and associated factors among primary healthcare workers. The study design was cross-sectional and services-based, in 240 primary healthcare units in 41 municipalities (counties) with more than 100 thousand inhabitants in seven States in the South and Northeast regions of Brazil. A total of 4,749 primary healthcare workers were interviewed, and prevalence of minor psychiatric disorders was 16%, with no statistical differences according to region or primary care model. The rate was higher in community health workers and other workers with secondary education (18%) and lower in health professionals with university training (10%); while physicians (15%) and nurses and nurse technicians (14.6%) were in an intermediate situation (p < 0.001). Occupational characteristics showed the strongest association with the occurrence of minor psychiatric disorders according to the adjusted analysis, suggesting that their reduction requires improvements in work conditions in primary healthcare and in the management of the Unified National Health System.
