Introduction and objective: Brazil has the highest 12-month prevalence of major depressive disorder in the world. This study explored management of depression by adult Brazilians.
Methods: The National Health Survey, Brazil 2013 data for 60,202 adults who responded to the individual questionnaire was used. Persons with current major depressive syndrome were identified and ascertained with the PHQ-9 (PHQ-MDS) and self-reported diagnosed depression. Self-reported depression management were explored. Factors associated with being diagnosed with depression were investigated using multivariate Poisson regression analysis. Appropriate weights and control for the survey design were incorporated in all analyses.
Results and conclusions: 4.1% (95% CI 3.8-4.4) of the sample population had PHQ-MDS, of whom only 37.8% (95% CI 34.5-41.2) reported being diagnosed with depression (mean age at diagnosis: 36 years). Having superior education, living in the South/Southeast/Midwest, having a physical morbidity, frequently consulting medics in the past 12-months were positively associated being diagnosed with depression. Opposite associations were found for age ≥85 years and living in rural areas. Gender, binge drinking, days with disability and having private health insurance were not associated with being diagnosed. 71.1% of people with PHQ-MDS and diagnosis were currently treated for depression (66.5%: antidepressants, 24.8%: psychotherapy, 1.6%: other) and 70.6% were referred to or seen by a mental-health professional. Half of diagnosed people did not see routinely a doctor/healthcare services about their depression (21.3% because they thought they were no longer depressed). In Brazil, depression is often undiagnosed by healthcare professionals and diagnosed depression is often untreated and unmonitored.
