Objective: To identify the prevalence of and factors associated with: (1) major depressive episodes; (2) minor psychiatric disorders (MPDs); and (3) suicidal ideation among nursing professionals from a municipality in southern Brazil.
Methods: Using a cross-sectional design, we recruited 890 nursing professionals linked to 50 Primary Care units, 2 walk-in clinics, 2 hospital services, 1 emergency room service, 1 mobile emergency care service, and 1 teleconsultation service, in addition to the municipal epidemiological surveillance service and the vacancy regulation center between June and July 2020. We used the Patient Health Questionnaire-9 and the Self-Reporting Questionnaire to evaluate the studied outcomes. Associations between the outcomes and variables related to sociodemographic profile, work, health conditions, and daily life were explored using Poisson regression models with robust variance estimators.
Results: The observed prevalence of depression, MPDs, and suicidal ideation were 36.6%, 44%, and 7.4%, respectively. MPDs were associated with the assessment of support received by the service as 'regular' (PR: 1.48; 95% CI: 1.19-1.85) or 'poor' (PR: 1.54; 95% CI: 1.23-1.94), with a reported moderate (PR: 1.63; 95% CI: 1.29-2.07), or heavy (PR: 2.54; 95% CI: 2.05-3.15) workload, and with suspected COVID-19 infection (PR: 1.44; 95% CI: 1.25-1.66). Major depressive episodes were associated with a reported lack of personal protective equipment (PR: 1.20; 95% CI: 1.01-1.42), whereas suicidal ideation was inversely related to per capita income > 3 minimum monthly wages (PR: 0.28; 95% CI: 0.11-0.68), and positively related to the use of psychotropic drugs (PR: 3.14; 95% CI: 1.87-5.26).
Conclusion: Our results suggest that nursing professionals' working conditions are associated with their mental health status. The need to improve working conditions through adequate dimensioning, support and proper biosafety measures is only heightened in the context of the COVID-19 pandemic.
